2 Unit Overview
The unit is designed to offer operators a high level of reliability and flexibility. It
consists of a chassis in which a number of hot-swappable modules can be installed.
In order to match specific system requirements, the chassis can be configured to host
the functional modules best suited for a given scenario.
Appear TV products can be delivered in two different chassis variations; a 1 RU
chassis and a 4 RU chassis. The product description DC1000, SC2000 and MC3000
represents the 4 RU chassis, while the product description DC1100, SC2100 and
MC3100 represents the 1 RU chassis. Both chassis variations use the same HW
modules and run the same SW.
The 4RU chassis consists of a total of 18 slots which can all host functional modules.
Slot number zero is dedicated to host the switch module and slot number 17 can only
host multi-slot functional modules except the HP DUAL DECODER RF MOD STEREO
and the QAM OUTPUT modules. Alternatively, in a DC1000 configuration, a second
switch module can be placed in slot 17. The remaining 16 slots are identical and can
be occupied by any of the functional modules available. A 4 RU chassis including a
mandatory switch module, power supply connectors, and module slots is shown in
Figure 1. Power modules and switch modules are inserted from the back (not shown).
Figure 1 – 4RU chassis with power connectors, switch module and available slots.
The 1RU chassis consists of a total of 9 slots plus a slot for the switch module.
Modules can be inserted from the front and from the back. The modules inserted in
the front are not hot-swappable and can only be serviced by factory or by authorized
service facilities. The modules inserted in the back can be services in the field. The
mandatory switch module is placed in slot 0 located in the front upper right corner
behind the front cover. Slot 1 is in the front below the switch module and slot 8 and 9
are in the front on the right side. Slot number 2 to 7 is in the back as illustrated in
Figure 2. Slot 1 can only support IP IO module or a descrambler module. Slot 8 and 9
can only support descrambler modules. Slot 2 to 7 can hold any 1 or 2 slot wide
module available.

3 Installation
This chapter describes the installation procedure for the unit.
3.1 General Considerations
Rack size:
The chassis is designed to be installed in a standard 19” rack.
Ventilation:
The 4RU chassis with Telco mounting has forced air flow from front to back in the
chassis, allowing for multiple units to be stacked above each other with no space in
between. However, adequate space must be provided in front of and behind the unit
for effective ventilation to take place. For a Broadcast mounting, the airflow will be
from the back to the front.
The 1RU chassis has forced air flow from left to right side allowing for multiple units to
be stacked above each other with no space in between. However, adequate space
must be provided on the sides for effective ventilation to take place.
3.2 Connecting Power
Power supply rating:
The 4 RU chassis can be supplied with a 100-240 V AC 50/60 Hz power or -48V DC
power. The 100-240 V AC 50/60 Hz power supply is rated for maximum 325W. The
-48 V DC power is rated for maximum 300W.
The 1 RU chassis can be supplied with a 100-240 V AC 50/60 Hz power rated for
maximum 200W.
Power supply module replacement:
The 4RU can be fitted with either one or two power supply modules. Power supply
modules can be hot-swapped from the back of the unit. A chassis delivered with
single power can later be upgraded in the field by purchasing an additional power.
The 1RU chassis is delivered with single power. In case of failure, the chassis must be
returned to factory for service.
Dual power supply units:
For units with dual redundant hot-swappable power supplies, if a power fails the
remaining power supply will handle the power consumption of a full chassis. The
recommendation is to connect the two power inlets to different mains power circuits.
3.3 Connecting Input Signals
Please refer to Appendix A. Hardware Modules for module identification.
3.3.1 IP Input
The IP input module is equipped with 2 electrical connectors (RJ45) and one optical
connector (via SFP module). One of the RJ45 electrical connectors and the optical
connector are for data, while the second electrical RJ45 connector is for management.
SW Version 2.04
30-January-2009
Page 4 of 128
Automatic sensing of 10/100/1000 Mbit Ethernet connections is supported. For a
1000 Mbit connection, the Ethernet cable must be a category 6 cable.
The IP address for both the electrical (RJ45) and the optical (SFP) connectors for data
is the same: consequently both cannot be used simultaneously. Both inputs are
automatically activated by IP connection. The first port activated (establishing a link
towards the router) will be the active port. To activate the other port, the cable on the
active port must first be removed.
3.3.2 ASI Input
Each ASI input module has 3 independent ASI inputs. The ASI connector is a 75Ω
BNC connector. The maximum input rate per connector is 213 Mbit/s in burst mode.
The ASI module is equipped with an electrical (RJ45 connector) for management.
Automatic sensing of 10/100/1000 Mbit Ethernet connections is supported. For a
1000 Mbit connection, the Ethernet cable must be a category 6 cable.
3.3.3 QPSK Input
Each QPSK input module has 4 independent QPSK L-Band inputs. Each input can
either be connected directly to an LNB, or alternatively to an L-Band distribution
amplifier or a switch. Each input is a 75Ω F connector. The maximum input level is 25 dBm. The recommended input level is between -30 dBm and -40 dBm.

3.4.5 Decoder with RF Output
3.4.5.1
Dual Decoder with RF Modulation
For modules with built-in modulation and RF up-conversion, the RF up-converted
output is a female F-connector, one for each TV channel. The upper connector is
channel A while the lower connector is channel B.
The standard version of the RF output covers the complete band from 47 MHz to 862
MHz. Alternatively the RF modules can be delivered with a low spurious option. For
the low spurious option, the frequency range is divided into the following three bands:
Low Band
47 MHz to 340 MHz
Medium Band
330 MHz to 620 MHz
High Band
500 MHz to 862 MHz
For the low spurious option, each output is marked with frequency band. The
available frequency range is reflected in the GUI by only presenting legal values.
The RF output can be muted by an eternal system by applying 5 V to the mute
connector. Channel A and channel B can be muted individually. The dual decoder with
RF modulation is 2 slots wide.
3.4.5.2
Dual Decoder with RF Modulation and Stereo Sound
The RF output is the same as in for section 3.4.5.1 with the addition of a NICAM
stereo sound carrier or A2 stereo modulation.
SW Version 2.04
30-January-2009
Page 8 of 128
In addition to the RF output described in section 3.4.5.1, the module has a female
DSUB9 interface connector that can be used for controlling redundancy switching. If a
critical alarm is detected, the DSUB9 interface will go from OK state to ALARM state
after a set period and the built in relay will change its pin configuration according to
the following table:
OK
Pin 1-6 open
Pin 2-6 closed
Channel A

Table 1 - Alarm relay states.
In order to avoid unnecessary switching on the output, a hysteresis scheme has been
implemented.
If the initial relay state is OK and a critical alarm condition is detected for more than 5
seconds, the relay state will signal an ALARM condition, and the DSUB9 interface
configuration will change according to Error! Reference source not found..
If the initial relay state is ALARM and all critical alarm conditions are cleared for at
least 60 seconds the relay state will go back to OK, and the DSUB9 interface
configuration will change according to Error! Reference source not found..
The RF output can be muted by an eternal system by applying 5 V to the mute
connector. Channel A and channel B can be muted individually. The Dual Decoder
with RF Modulation and Stereo Sound is 3 slots wide.
3.4.5.3
High Performance Dual Decoder with RF Modulation and
Stereo sound
The High Performance Dual Decoder Module will provide the same output as the
standard RF up converter, but with improved RF specifications. The RF up-converted
output for the two channels are combined internally and presented on a single female
F-connector.
The module has a test output with both channels. The test output connector is a
single female F-connector and the power level is -23 dB from the main output.
The module covers the complete VHF/UHF band from 47 MHz to 862 MHz and NICAM
or A2 stereo is provided as a SW option. A module delivered as mono can later be
upgraded to support NICAM or A2 stereo by purchasing a SW licences.
The RF output can be muted by an external unit by applying 5 V to the mute
connector. Channel A and channel B can be muted individually. The High Performance
Dual Decoder with RF Modulation and Stereo sound is 2 slots wide.
SW Version 2.04
30-January-2009
Page 9 of 128
The High Performance Dual Decoder card replaces the Dual Decoder RF module as of
end Q4 2008, and will also be used as the up-converter module for Dual Decoder RF
with stereo sound.
3.4.6 FM Radio output
For the FM radio module, with built-in FM modulation and up-conversion to the FM
band, the FM up-converted output is a female F-connector.
Each module can offer up to eight channels. The FM output can cover the complete
band from 47 MHz to 862 MHz.
The options to enable RDS or insert RDS information, as well as enable outside
management are presented in the GUI.
The RF output can be muted by an external system by applying 5 V to the mute
connector. Muting the input mutes all channels available on the RF output connector.
The FM radio module is 1 slot wide.

4 Configuration
4.1 Administrative Settings
This chapter describes how to do the initial configuration of the unit such as setting
the unit IP address, changing the GUI password and setting the unit time.
4.1.1 Accessing the Web Interface
All modules in the unit are controlled via the web interface provided with the unit.
The unit management software runs on the module configured as Man Machine
Interface (MMI). Normally the MMI is installed on the module in slot 1, however any
input module can be configured as the MMI module. Only one module in the chassis
should be configured with the MMI option.
All modules with MMI are configured with a default IP address of 192.168.1.100. To
change the network settings of the device please follow the steps described below.
Connect a PC directly to the device (the Ethernet port marked “control” on the master
module – usually in slot 1) with an Ethernet cable
Set the IP address of the Ethernet adapter of the PC to a fixed address in the same
segment (e.g. 192.168.1.99). Please refer to the operating system manual for setting
the IP address on the PC.
Start an internet web-browser and type 192.168.1.100 in the address field.
The following screen will appear (exact configuration of the unit will vary):

Type in the password and press Set. Then press close to exit the dialog.
4.1.5 Optional Languages
It is possible to specify one or two default languages which will always be available
when configuring a decoder module. Since the drop-down list of available languages
only includes the languages currently present in the transport stream, this enables the
operator to select languages expected to be present in the transport stream at a later
point in time.
Open the Admin folder in the navigation pane and select the module hosting the
management interface (MMI).
Figure 8 - Optional Languages
Enter up to two additional languages in the Optional Languages box. Language

4.2 Licensing
Some of the features are licensed. You will get a warning when accessing functions
with licensed features. In the future these pages will be completely locked for users
without the proper licenses. Use the ‘License’ tab to find which licenses are acquired
and which are available.
4.2.1 Installation
A license file must be acquired to get a license. It contains one or more serial
numbers. The serial number of the MMI card must be included for the license file to
be valid. The file format is human readable but signed, and it is invalidated by
changing the file. This might happen if the file is transferred with ftp in ASCII mode.
Figure 9 - Licensing
When the file is available from a machine with access to the web GUI, select the file
and ‘Install License’. If no warnings are received, the additional privileges should now
be available.
4.3 Configuring Inputs
The unit can be configured to host a number of different input modules. Open the
Inputs folder from the navigation pane to view all the available input modules. See
Figure 10.
SW Version 2.04
30-January-2009
Page 16 of 128
Figure 10 - Inputs view
The following information is displayed in the Inputs main display pane:
Slot
Slot position in the chassis
Type
Type of input module
Services
The number of services present in the transport stream
Total Rate [Mbps]
The total bandwidth of the incoming transport stream
CC Errors
The number of CC errors detected on all input ports
For each input module available in the unit they all have some common analysis
features and they all support manual definition of input PSI. The next sections will first
describe these common features, before the configuration of each available input
module will be described.
4.3.1 Input Analysis
For each listed input module the unit provides detailed MPEG/DVB transport stream
analysis for all the available input streams. The following information is provided by
the input analysis engine.
Port specific status
PSI/SI analysis of all input services
PID display: listing all input PIDs for each input, with implicit highlighting of CC
errors, PCR flag and scrambling bits (odd/even)
This information is accessible by drilling down into the Inputs node in the navigation
tree. The following example is based on a QPSK input, but the same applies for all
input modules.
SW Version 2.04
30-January-2009
Page 17 of 128
Highlighting the input module will display all the ports with their input configuration in
the top pane, and it will list all the services detected for the entire input card in the
lower pane. This upper pane shows the total input rate for each port, the number of
CC errors and the configuration parameters currently set for each port.
4.3.1.1
Input Port Analysis
From the input card view it is possible to access the next level of information such as
for the port specific information. For all the input cards with demodulators click on the
port letter on the left hand side in the top pane and the port specific information will
be displayed. For the IP input card there is no more information available then the
one shown on the top pane only.
The QPSK port detailed view:
For a description of the actual parameters please refer to the configuration section for
the respective input type in this chapter.
4.3.1.2
Input Service Analysis
It is possible to apply filters on the information displayed in the lower pane. Selecting
the QPSK service view (by clicking the “view” link in the “Service” column), only the
services associated with the selected input will be displayed in the service listing view.
To access detailed PSI/SI analysis of the input services just click the respective
service in the lower pane. The detailed analysis result will appear on the right hand
side in the lower pane.
SW Version 2.04
30-January-2009
Page 18 of 128
Note that this is not a 100% DVB Compliant analysis but it does support the most
interesting tables and descriptors.
The Audio language descriptor is decoded, but if no language descriptor is present the
unit will auto-generate a descriptor for internal usage; as shown above the audio is
listed as A0. If more audio PIDs had been present without a language descriptor they
would get the named A1, A2 etc.
4.3.1.3
Input PID Analysis
For each port the PID view lists all PIDs detected for the given port. This list is
accessible by pressing the PIDs view column in the top pane.
For an input containing scrambled services the colour of the scrambled PIDs will
toggle between Blue and Read as the ODD / EVEN bit toggles.
In the above view wee can see that PID 2101 is scrambled (it is coloured) and that it
contains PCR (it is in bold), and that one or more CC errors has occurred for PID 20.
It is possible to reset the CC error counters. This reset is a global operation for all
inputs and is done with the “Reset CC” button in Inputs tab view in the navigation
tree. See figure at the start of this chapter.
Further more it is possible to click on a PID in the PID view to get PID specific details.
Selecting PID 20 we see that this is the TDT PID, and that the bitrate and the number
of CC errors are presented.
Selecting PID 2101 gives a slightly different info as this is a video PID:
SW Version 2.04

Page 19 of 128
4.3.2 Manual PSI
The Manual PSI feature allows manual definition of input PSI. This feature is normally
not used as most inputs do contain correct PSI. In some cases however it is beneficial
to define the PSI manually.
The input does not contain PSI, or in-correct PSI.
The input is not available, and a pre-definition of the PSI is necessary in order to
configure a service that is occasionally available. This could for instance be used to
predefine some services for a dynamic VOD usage.
To manually define input PSI go to the Inputs->Manual PSI tab in the Navigation tree.
Enter the appropriate values matching the incoming stream. Note that the PMT PID
may be defined to any value between 32->8190, but make sure it is unique in an
MPTS configuration scenario. Also be aware if this input is part of an outgoing digital
stream the PMT PID entered here is the PID value that will be assigned for the
outgoing PMT.
When an input service is defined the following tables are generated:
PAT
PMT
1 Video PID
1 Audio PID with Language descriptor from audio
All other table analysis is cancelled.
SW Version 2.04
30-January-2009
Page 20 of 128
And the result is listed in the GUI. This entry may then be edited later or deleted by
pressing the appropriate icons to the left in the list.
MPTS Support: If multiple services are defined for one input it effectively represents
a MPTS.
To check that the manually defined input has entered the systems correctly go to the
inputs view and check that the service information is present. In the below example
input 20 is represented with PSI even if the input is not yet added into the system.
Note:
If manual PSI is defined for an input port, then all the incoming services must
be defined. It is not possible to define one service manually, and use the
incoming PSI to represent the rest.
4.3.3 QPSK Input
Each QPSK module can receive up to 4 individual QPSK input streams. To configure
the module, please:
Open the Inputs folder in the navigation pane, open (click on) the QPSK tab and the

4.3.8 IP Input
4.3.8.1
General Configuration
The unit can be equipped with a number of different IP input modules. Each IP input
module is capable of receiving up to 250 individual input streams. The input streams
can be either SPTS or MPTS encoded.
In order to add new inputs, remove input or view info regarding existing inputs:
Open the Inputs page from the navigation pane and choose the IP input module you
wish to configure. See Figure 21. The services available on all inputs will be listed in
the same view by default (in the bottom half of the main display window).
Figure 21 - IP input page
The IP input window shows all configurable settings as well as the current bit rate and
service information. The following parameters are available:
Input
Shows the input number
IP
Shows the IP address of the multicast/unicast.
Port
Shows the port.
Service

De-Jitter
This check box activates the de-jitter algorithm on the input
port. Normally this should be enabled in order to achive the
best results. In some cases if the input quality is very poor a

better result may be achieved by disableing this feature,
note however then the output from the streamer will be very
poor as well.
Adding a new input stream
In the Input Control pane (on the extreme right of the main display window), add the
multicast/unicast IP address and port.
Click the Add button. The input module will now issue an IGMP join for the selected
multicast and start to analyze the incoming stream. The service found on the selected
multicast will be listed in the service view in the lower part of the input page.
Removing a multicast input
Select the input to be removed by activating the tick box on the left hand side of the
input entry (in the “Existing IP inputs” pane).
Click the Selected button under the Remove input part of the input control.
It is possible to apply filters on the information displayed in the GUI. Selecting the
Service View for a selected multicast, only the services associated with this multicast
will be displayed and clicking on one of the listed services will display more detailed
information about the different PIDs like PMT, PCR, video, audio, etc. Selecting the
ASI PID View will display only the PIDs associated with the selected input. It is also
possible to click on any of the PIDs to get more detailed information about that PID.
4.3.8.2
Overview
IP Input Redundancy
Input redundancy is designed to handle redundancy on the input streams. Input
redundancy will remedy failures from outside the system, such as with a cable breakdown, which result in link loss on the IP input module and the absence of a bitrate on
the dataport.
The chassis will have two IP input modules. One IP input module will be configured to
serve as the main module while the other will be configured to serve as backup. In
the event of input source failure, the IP input source will switch automatically.
It must be noted that input redundancy configuration is only supported for IP input
modules.
Hardware requirements
The system must be equipped with at least two IP input modules. If there are only
two IP input modules, the main module must have MMI functionality. One module is
designated the main module and must have MMI functionality, while the other is
designated the spare module.
If there more than two input modules in the chassis, any module can host the MMI
functionality without affecting redundancy.
The redundant module must have the same input configuration as the main input
module (configuration is mirrored). The selected redundant IP input card cannot be
configured manually, and is not available for separate use.
Alarms that cause switching
The system will automatically switch from main source to backup source based on the
presence of the following two alarms:
SW Version 2.04
30-January-2009
Page 33 of 128
NO LINK ALARM on
data interface
The NO LINK alarm will be raised if the GigaBit IP input
module detects no link over a period of 1 second.
Possible causes for the alarm are link loss or no-lock on
input card.
NO SIGNAL ALARM on
data interface
The NO SIGNAL alarm will be raised if the GBIP input
card detects no bit rate on all the configured IP inputs
over a period of 1 second.
Note:
These alarms and the switching hysteresis are not configurable
When an alarm leading to a switch has been triggered on the main card, all
routed streams are switched from the main module to the spare module. The
switch will be effectuated even if an alarm is active on the spare card.
MMI functionality remains on the same card after a switch
Switching can be done manually from GUI
There is no automatic switching from spare to main module if/when alarms are
cleared. This must be done manually.
Alarms which are filtered through the alarm filter GUI will not trigger source
switching.
MMI
Input redundancy does not affect MMI functionality. If the main input module is
configured as supporting the Man Machine Interface (MMI), this configuration will
remain even though all input sources are switched from Main to Backup card. It is for
that reason that there is always a mirror configuration on both cards.
Before implementing redundancy
Before configuring input redundancy, it is necessary to configure the main IP input
module. This is done through the Inputs->IP tab in the navigation pane. The
configuration of the main input module will then automatically be mirrored to the
redundant IP input module in the redundancy configuration – the operator need not
do any manual configuration of the redundant IP card.
Configuring an input module as either main or backup:
Once IP modules are inserted, and the main module configured, clicking the Input
tab under the Redundancy tab in the navigation pane will open the Input
Redundancy setup display
Figure 22 - Source redundancy setup
To configure input redundancy, select the modules to be used as main source and
spare source from the pull down menus. Then click Add to add the redundancy
configuration to the system.
SW Version 2.04
30-January-2009
Page 34 of 128
Note:
All SPTS/MPTS inputs that are configured on the main input module will
automatically be mirrored to the backup input module when configuring main
and backup sources.
Clicking Add shows the redundancy pair configuration.
Figure 23 - Input redundancy pair
On this page the modules paired as main source and spare source are displayed.
The Status field shows the current redundancy status, which can be either:
main – Inputs are routed from the main input module.
backup - Inputs are routed from the backup input module.
Clicking the Switch button will change the current active input. If current active input
is main, the input source will switch to backup and vice versa.
Clicking the Remove button will remove the redundancy pair.
Switching from main to backup
Changing the input source from main to backup (either automatically through the
presence of the alarms above, or due to user interaction), will raise an alarm
indicating the cause of the switch. This alarm will remain active until a manual switch
from backup to main is performed.
In addition, when an alarm leading to a switch has been triggered on the main
module, all routed streams are switched from the main input module to the spare
input module. The switch will be implemented even if an alarm is active on the spare
input module.
Switching from backup to main
Changing status from backup to main (switching inputs from the backup module to
the main module) will clear the alarm generated when switching.
There is no automatic status change from backup to main even if or when alarms are
cleared. This has to be done manually through the GUI.
A word about IP input module configuration
IP inputs for the main and backup sources are done through the IP inputs page for
the main input module. All added/removed inputs will automatically be
added/removed from the backup input module. Accessing the inputs page for the
backup module will only show the status of the inputs on the backup module.

4.3.8.3
Overview
Internal Redundancy
Internal redundancy refers to the process by which decoder can receive configuration
from two different MMI boards, but not at the same time.
The chassis will have two switches. One switch will be configured as the main switch
while the other switch will be configured to be the redundant switch.
There will be two input cards, one for each switch. It must be noted that decoder
redundancy configuration is currently only supported for IP input modules.
Hardware requirements
The following hardware is required for the implementation of decoder-controlled input
handling redundancy:
2 IP input modules
The unit must be equipped with at least two IP input modules.
2 switches
Decoder cards.
For decoder-controlled input handling redundancy to be
implemented, switching configuration must be known at set
up. Therefore both IP input cards must have MMIs (though
one will be redundant). It should be noted that both IP input
modules do not need to have the same configuration.
Input redundancy: it should be noted that dual input and decoder-controlled input
handling redundancy on one unit is not supported.
Alarms that cause switching:
Decoder-controlled input handling redundancy will be implemented with the following
alarm:
Transport Stream Missing
Internal link down
No contact with input card
Switch alarm
It should be noted that should a problem on one stream causes one decoder to
switch, the other decoder on the decoder module will also switch.
Alarms displayed as a result of the switch
Switched, reason: link
down
This refers to internal link failure.
Switched, reason: logout
The decoder card is logged out from the input card
hosting the MMI.
Switched, reason: alarm
This alarm refers to input stream failure having caused
the switch.
Switched, reason: operator
This alarm refers to the operator having performed a
SW Version 2.04
30-January-2009
Page 36 of 128
manual switch
There is a delay of 60 seconds before the alarm appears. When both channels are
configured with a service, the decoder card will switch if both Channel A and Channel
B meet switch criteria. If just one channel is configured, then the decoder will switch if
that channel (A or B) meets the switch criteria. There will be only one alarm when
the decoder switches (not from both channels).
Signal flow within the unit when having two backplanes
The figure below shows the signal flow within the unit when having two backplanes,
one MMI card connected to backplane 1 and second MMI card to backplane 2
respectively.
Decoder switch reasons
If decoder looses link with the switch to which it is currently connected, it will try to
switch. This can be simulated by actually removing the switch for Backplane 1 (The
blue one). The effect will be that the Decoder will stop communicating on the blue link
and connect to the second backplane (the red one)
If a problem is detected in the configured Decoder Channels, i.e. if transport stream is
missing on both the channels when both are configured, then decoders will switch to
the other backplane. This can be simulated by actually removing the data cable for
Input card or by stopping the input signal.
Note 1:
Internal redundancy must be enabled to be able to switch.
Note 2:
If both channels, A and B, are configured with a service in the GUI, it requires
both of them to have a problem. If just one channel is configured, it requires
just the configured channel to have a problem for meeting the criteria for
switching to the other backplane.
Note 3:
Removing inputs from GUI will not cause decoder cards to switch.
Example when switching does not occur
When you remove the inputs, i.e. you remove the configuration of the input streams
you have a system with the following configuration.
SW Version 2.04
30-January-2009
Page 37 of 128
This causes the input card to no longer subscribe to the multicast input, and also tells
the system to not configure the decoder. And a decoder without a configuration will
not try to switch, as nothing is wrong.
Configuring modules for internal redundancy through the user interface
Configuring internal redundancy is done through the Redundancy tab in the
navigation pane. From there, open the Internal tab in the sub-tree - this will open
the configuration page in the web GUI.
General display
The configuration page shows two sections: Twin MMI card and Internal
redundancy supported cards. First section is used to add IP address of the twin
MMI board second section lists a row for each decoder on the module. The decoded
service is displayed, and can take the values of either “the service name” or “off”.
Twin MMI card
In order for the internal redundancy GUIs to know about each other it is important to
enter the IP address of the other MMI board in the dialog below. The other MMI board
is referred to as the “Twin MMI”. The effect of adding the Twin MMI is that the MMI
boards exchange the card list between each other. All other configuration MUST be
done separately on each MMI board.
Note that in order for this to work it is essential that the two MMI cards have an IP
connection.
SW Version 2.04
30-January-2009
Page 38 of 128
Figure 24 – MMI correlation
The purpose of MMI Correlation is to get rid of the card missing alarms on the spare
MMI board. The “Status” column displays whether the module in the slot is logged
into the MMI board or not. On spare MMI board card status “Logged in to twin MMI”
shows that this card is logged in to the other MMI board.
Figure 25 - MMI correlation (spare MMI)
An alarm with the message Unable to communicate with TWIN MMI is generated
whenever connection breaks between MMI Input cards.
This alarm will be triggered if the twin MMI IP address from the GUI is removed, one
of the input cables is disconnected, or one of the MMI cards is removed.
Enabling redundancy
The “Enabled” check box must be selected to enable redundancy on the card. Each
Decoder can be configured at anytime no matter which backplane is logged in to.
Switch Delay
Once the decoder meets the described conditions to log in to the twin MMI
automatically, it still needs to wait a determined switch delay period of time. This
hysteresis period is configurable for each decoder card in the Switch Delay text field
located in the Internal redundancy supported cards section.
The value is captured by the MMI in seconds. The minimum value allowed is 8
seconds, and the default value is 15 seconds. If it is needed, the same decoder can
have a different Switch Delay value for each backplane, and it can be modified in the
MMI even when the Decoder is connected to the other backplane.
After the switch delay time is reached, the Decoder card will switch to the twin MMI. If
the login succeeds and the input signal is correct, the video and sound will be back on
the screen.
SW Version 2.04
30-January-2009
Page 39 of 128
Performing a manual switch (by operator through GUI)
The “Switch” button enables the operator to perform a manual switch from the GUI.
This button is available when Internal Redundancy is enabled. The Decoder will switch
right after the operator clicks the button without waiting any Switch Delay time.
Figure 26 - Internal redundancy
Reboot
The decoders are designed to log into the first available MMI board. They will always
try to login to the Main MMI board first, which is connected to default backplane. But
only during the boot process, if login fails through the default backplane, it will try to
connect to the backup even if internal redundancy is disabled.
4.4 Conditional Access
The unit supports descrambling and scrambling given the required modules are
installed in the unit. These functions are regarded as processing elements and
therefore not listed in the input or output sections in the. The configuration of these
functions is found as part of the output service configuration.
4.4.1 Descrambling
The unit is capable of descrambling a number of incoming services with the
installation of a descrambler module. The descrambler module comes with two
Common Interface slots and can therefore host two Conditional Access Modules
(CAM’s). Each Common Interface slot supports descrambling one or more services
depending on the CAM module used. Please note that all for each CAM the services
must originate from the same input source. A descrambled service may be sent to
one or more output modules.
4.4.1.1
Descrambling a service
To descramble a service first insert the CAM into an available Common Interface slot,
then insert your Smart Card into the CAM.
Assign the Common Interface slot to a service that needs to be descrambled. This is
done in the service edit box in the output configuration page.
SW Version 2.04
30-January-2009
Page 40 of 128
4.4.1.2
Descrambled service to multiple output modules
A descrambled service may be sent to up to 4 individual outputs. I.e. if the unit is
configured with an IP-out and a QAM-out card, then the descrambler card will be able
to copy the descrambled service and send it to both the IP out and QAM-out
destinations. The configuration of this is automatically performed by the system when
an input service is configured to be sent to different outputs, and when the same
descrambler is selected.
The copy function is per service, hence if a smartcard is able to descramble up to 10
services, then the maximum number of streams out from the descrambler will be 40
(10 x 4).
4.4.2 CAM Configuration / Interaction
Inside the CAM Configuration page (Figure 27) the user can find a list of available
CAM Modules with its corresponding module name, the chassis slot where the
DDM/Descrambler card is placed and the CAM Slot (each DDM/Descrambler has two
CAM slots, named A and B). If there is not any CAM Module inside the
DDM/Descrambler card, the CAM Name will be displayed as not available. The CAM
Configuration page can be opened by clicking on the CAM Tab located under the
Conditional Access tab in the navigation tree.
The Alt CAM Mode, CAM Interface, Reset and Max TS Rate are the configuration
fields available in this page (Figure 27).
SW Version 2.04
30-January-2009
Page 41 of 128
Figure 27 – CAM Configuration page
4.4.2.1.1
Alt CAM Mode
The operator can enable/disable the Alt CAM Mode from this page (Figure 27).
Normally a single PID is sent to the CAM, but with the Alt CAM Mode the whole input
stream is sent directly without doing any PID filtering.
4.4.2.1.2
CAM Interface
Each CAM Module has its own menu structure defined by its manufacturer to
access module information such as subscriptions status and to insert
configuration data such as a new PIN Code, maturity rate, or even a key to
descramble a service.
The CAM Interface feature allows the operator to access and interact with these
menus with ease through the Web GUI. By clicking on Open under the CAM
Interface column, a pop-up box appears over the CAM Configuration page. This
is the CAM Interface dialog.
Navigation
As can be seen on Figure 28, the standard CAM Interface dialog provides two
buttons in the bottom and a list of clickable menu options. The Back/Exit button
cancels the current menu and shows the previous menu. If the Back/Exit button
is pressed on the top-level menu, the same menu screen will be returned. The
Close button stops the interaction with the CAM Module, closes the CAM
Interface dialog, and makes the CAM Configuration page controls available
again.
SW Version 2.04
30-January-2009
Page 42 of 128
Figure 28 - Example of menu from PowerCam_HD V2.0.4
During menu navigation, the operator may see other types of dialogs besides the
menu style on Figure 28. After choosing a menu option, the operator may get to
menu screens which do not allow interactions. These are called Lists. Lists are
bottom-level menu items and for that reason, the only possible operations are to
go back to previous menu, or to close the CAM Interface (Figure 29).
Figure 29 - Example of List from CryptoWorks.
Another type of dialog is the Enquiry (Figure 30). This dialog is displayed when
the CAM Module requires user input such as a PIN code. The CAM defines the
maximum length of the input data and whether the actual characters are
displayed as the user types.
Figure 30 - Example of Enquiry from CryptoWorks.
SW Version 2.04
30-January-2009
Page 43 of 128
Multiple Users
The CAM Interface supports multiple users but not multiple sessions. This means
that it is possible to access the CAM Interface of the same CAM Module from
different computers or browsers simultaneously, but users can not be on different
levels of the menu. For this reason the CAM Interface gets refreshed every 10
seconds to request the current valid menu screen.
Due to this synchronization scheme the menu screen will change for all current
users even if just one of them interacts with the CAM Interface dialog.
Multiple users interacting with a single CAM Module can lead to synchronization
errors. For instance, when one user tries to access a menu that has not been
refreshed after another user has interacted with it, a synchronization error will
occur. This will display a “Status” error. These and other errors are handled by
the CAM Interface to provide a safe and consistent interaction.
Error Handling
When a situation results to be problematic, and does not permit to have the
correct communication with the CAM Module, an error message will be displayed.
There are different conditions that can lead to an error, and the error messages
that correspond to it.
Error Message
Description
"Error: No session.
Refresh to recover
communication"
"Error: Session ID.
Refresh to recover
communication"
"Error: Status. Refresh
to recover
communication"
The user is trying to answer a menu or
enquiry and the session has been closed.
"Error: Invalid message
format"
The message parsing process is not
successful.
"Error: CAM No
response. Refresh to
recover communication"
"No CAM/PC Card in slot"
Within a specified timeout, the CAM Interface
failed to respond.
"CAM/PC Card needs
reset"
Is sent when CAM Card needs reset.
"PC Card not identified,
or identified as nonCAM"
The PC Card is not identified, or identified as
non-CAM.
"DVB CAM detected but
block size negotiation
failed"
The DVB CAM is detected but the block size
negotiation failed.
SW Version 2.04
The user is trying to access a session that is
no longer available.
The status count value received from GUI is
not the same as the one in the CAM Interface.
This means that the GUI could be in another
level of the menu which can lead to a non
desired operation
There is No CAM Card in the slot.
30-January-2009
Page 44 of 128
When an error message is displayed, the Back/Exit button is replaced by a
Refresh button while the Close button remains (Figure 31). The operator can
just close the CAM Interface, or can try to refresh the session. The latter is the
ideal solution if a synchronization error occurs. Alternatively, the operator can
just wait for the CAM Interface to request a Refresh automatically.
Figure 31 – Error message.
4.4.2.1.3
CAM Reset
There could be situations when resetting the CAM module is necessary. For example,
if the CAM is not responding. To solve this kind of problems the operator can reset a
CAM from the GUI. The operator can reset the CAM with the Reset button located in
the CAM Configuration page.
4.4.2.1.4
Max TS Rate [Mbps]
The Maximum transport stream rate allowed for the CAM is the last element listed in the CAM
Configuration page. The user can choose among three values: 43 (default), 58 and 68 Mbps.
4.4.3 Scrambling
This section gives a brief overview of how scrambling is performed within the unit. It
introduces the different modules required and their purpose. It explains how to do the
initial setup of the CA cards required for establishing the ECM and EMM channel
connection to the CA system, and what to do to set up the actual ECM streams and
the EMMs. This chapter does not explain how to start scrambling, or how to add an
EMM to an output transport stream. For details regarding output configuration please
refer to section 4.7 Configuring Transport Stream Outputs.
4.4.3.1
Overview
Version 1.09 of the software introduces a new scrambling card with both the SCS and
the scrambler functionality on one single card, whilst the previous GBIO_SCS/DDMSCR platform has these two modules on dedicated cards. The functional overview
shown below describes both platforms.
SW Version 2.04
30-January-2009
Page 45 of 128
Figure 32 - GBIO_SCS / DDM-SCR scrambler architecture
Figure 33 - New ASIO based scrambler architecture
The SCS module is the master of the scrambling system. It is aware of the ECMG and
the scrambler module. Upon configuration the SCS card generates a CW, sends it to
the ECMG, which returns the ECM. The SCS then sends the CW to the selected
scrambler and transfers the ECM to the correct output card for play out.
Before it is possible to define an output stream with the scrambling properties it is
necessary to define the ECM generator, as the SCS needs to know where to contact
the encryption system. Next step is to define an ECM. The ECM definition associates a
CW id and access criteria. The output can now be defined and scrambled. When
configuring the output to be scrambled the ECM selection list implicitly represents the
CW and access criteria while the scrambler indicates which scrambler card to use, for
the new platform the scrambler must match the card which provides the ECM.
4.4.3.2
DDM-Scrambler Card Configuration
The DDM-scrambler runs on a dedicated card which supports the CSA and the AES
scrambling algorithm. The algorithm is implemented in separate FPGA images which
are loaded during boot. Consequently the card cannot support both algorithms
simultaneously. The algorithm to use is defined by the card options which are
described by an option file.
SW Version 2.04
30-January-2009
Page 46 of 128
SCR option file
To change between the AES and the CSA algorithm it is necessary to load an option
file. This file describes the desired characteristics of the card, and is read during boot.
There are two option files:
DDM_SCRAMBLER_AES_MQ.img
DDM_SCRAMBLER_CSA_MQ.img
Below is a sample option file for the AES scrambler:
<atvHeader protocol="ddmOptionsProtocol" version="1.0"/>
<atvBody>
<DDM_HWDef>
<SCRAMBLER is_scrambler_card="Yes" algorithm="aes"/>
<MQ use_mq_protocols="Yes"/>
</DDM_HWDef>
</atvBody>
To load an option file, please follow the same procedure as applied for loading
application software to the scrambler card.
Selective scrambling / Partial scrambling
The scrambler card supports selective and partial scrambling. This implies that parts
of the content are sent in clear. This selection is done per service and is enabled
during the configuration of the output stream.
4.4.3.3
ASIO-Scrambler Card Configuration
The ASIO-scrambler card runs both the SCS functionality and the scrambler
functionality on one single card. The Scrambler supports both the CSA and AES
scrambling algorithms. The algorithm is implemented in separate FPGA images which
are loaded during boot. Consequently the card cannot support both algorithms
simultaneously and the card needs to be predefined to run either of the images using
the atvcardsetup program on the command prompt on the card.
The scrambler card supports up to 250 scrambled services, with a maximum total
bitrate of 850 Mbps.
An overview of the scramblers present in the unit is available in the “scramblers” tab
in the navigation tree.
Figure 34 - Scramblers overview
This pane gives a general overview of how many ECMs and EMMs has been
configured as well as providing a dialog to select which scrambling algorithm to run on
the card. The options provided here are based on the information reported by the
scrambler card during startup.

Configure an ECM Generator Channel
A connection to an ECM generator is defined in the ECMG tab located under the
“scramblers->SCS” tab in the navigation tree. The connection to an ECMG will
establish a channel over which ECMs will be sent.

It is possible to add more than one ECMG connection. These connections may be to

vendor. Note however if the same system ID is used a real Simulcrypt will not work
as the CA Descriptor in the PMT will be the same for both ECMs.

4.5 Configuring Decoders
Information about the various Decoder modules available can be found in 3.4.4 and
3.4.5. As of end Q4 2008 all RF Decoders shipped will be the High Performance Dual
Decoder with RF modulation described in 3.4.5.3, referred as HP RF Decoder in this
section.
The decoder modules are configured using the “Decoders” tab in the navigation pane.
All available decoder modules will be listed by their slot position. The two channels for
each decoder module are identified with ‘Channel A’ and ‘Channel B’.
4.5.1 Channel Configuration
The chassis can be configured with multiple dual decoder modules. Please follow the
procedure below to configure the module.
Open the “Decoders” folder in the navigation pane and the window in Figure 43 will be

4.5.4 RF Parameter Configuration
For Decoder modules with up-converter the configuration page will display an Upconverter
section as in Figure 44.
RF Frequency sets the modulation frequency of the service. It is possible to select from a set of
predefined frequencies (according to the selected RF Channel list), or alternatively by entering a
specific frequency in the text box.
The following up-converter configuration parameters can be changed:
RF Channel list
Select which channel plan to use. The available options are ITU
(C.C.I.R), OIRT and User defined.
RF Frequency
Sets the carrier frequency of the output. It is possible to select
from a set of predefined frequencies (according to the selected
RF Channel list), or alternatively by entering a specific frequency
in the text box.
RF Power Level
Determines the power of the output signal. Power level boundary
values will depend on the Decoder module, and is shown by
hovering the mouse cursor over the text box.
RF Enable
Enables the RF signal on the output. The RF output signal will be
turned off when this is not enabled.
AVCR
This parameter adjusts the Audio carrier output level compared
to the video carrier output level. The resulting output level will be
the selected value down from the video carrier. Please note that
this is power and not amplitude. Nominal value and range will
depend on the Decoder module being configured.
VMD
Video Modulation depth. This level can be adjusted from 80 to
90%. This parameter is only available for the HP RF Decoders.
Clipping
Determines how video is clipped before modulation. Enabling
clipping result in video being clipped 5% above configured
modulation depth. Off means video is not clipped. This
parameter is only available for the HP RF Decoders.
CW mode
Continuous Wave Mode. The output will be an un-modulated
video carrier with no audio carriers present. This parameter is
only available for the HP RF Decoders.
Fine level adjust
Fine tune the output power level, see 4.5.4.1. This parameter is
not available for HP RF Decoders.
The decoder will perform an auto calibration of the power level to match the selected
power output level every time the system boots or a change has been applied to the
RF Frequency, the RF Power Level or the RF Enable.
4.5.4.1
Fine level adjust
This section is not applicable for HP RF Decoder modules.
SW Version 2.04
30-January-2009
Page 57 of 128
After the decoder has performed the calibration described above it is possible to finetune the power level through the Fine Level Adjust parameter. The slider makes it
possible to adjust the power level ±1dB. Fine level adjustment should only be used in
conjunction with an external power measurement (for example a power meter). The
following steps should be used to fine calibrate power:
Select RF Power Level and RF frequency and click the Change button. This will
configure the decoder and RF calibration will be performed (picture is automatically
turned to black while calibration is being performed). The power accuracy will be ±
1.0 dB. Please note that the unit should be warm to assure accurate power setting.
If accuracy higher than ± 1.0 dB is required, fine level adjustment must be
performed. Before starting fine level adjustment, turn the channel off on the main
input page. Turning the channel off will provide a black picture.
Click the checkbox next to the Fine Level Adjust slider-bar. Adjust the power setting
using external power measurements and click the Apply button. The fine level adjust
setting will not be activated before clicking the Apply button. Please also note that
fine level adjustment should only be performed when the unit is at operational
temperature (allow 15-30 minutes operation before performing fine calibration).
When the fine level adjustment has been completed, turn back on the service from
the main input page.
When the fine level adjustment has been enabled, the automatic calibration is turned
off since this only have an accuracy of ± 1.0 dB. All power calibration settings are
stored in the flash. At a power recycle, these power calibration settings are recovered.
When the unit comes back to the operational temperature, the power accuracy is
within ± 0.25 dB assuming same operational temperature.
Since the fine calibration is only valid for the selected frequency, frequency selection
and course power setting is disabled when fine level adjustment has been selected. To
change frequency or course power level, please deselect the Fine Level Adjustment
box and adjust the settings as required. A new automatic calibration will be performed
when the frequency or the course power level settings are changed.

4.6.3 Configuring RDS Output
The FM Radio module supports a subset of RDS data transmission as specified in EN
50067. The currently supported subset consists of the following RDS data signaling
elements: PS, PTY, RT, PIN, MS, “Clock-Time and Date” and “Slow labeling codes”.
RDS transmission is enabled when the appropriate input data source is selected from
the RDS Mode dropdown-list, the default is no RDS transmission (Off). Three
different sources of data are supported, Manual, Auxiliary UECP and Ancillary
UECP.
Manual enables the operator to enter PTY, PS and RT data.
Ancillary requires that UECP information has been inserted in-band into the MPEG
stream according to CENELEC European Standard EN 50067 (“Specification of the
radio data system (RDS) for VHF/FM sound broadcasting in the frequency range from
87,5 to 108,0 MHz”).
Auxiliary requires that UECP data has been inserted in a separate PID in a
proprietary format. Please contact sales for information about supported formats.
4.6.3.1
Manual RDS
PTY – Manual Programme TYpe: Offers all 31 programme types predefined in the
RDS specification.
PS – Programme Service: The field for the 8 character static display of the station

Ancillary and Auxiliary RDS
The configuration alternatives for ancillary and auxiliary RDS differs in that a data pid
may need to be specified for the auxiliary stream. When the auxiliary option is
enabled an extra parameter, Data PID, is visible on the configuration page. If a data
pid is not specified, the device will make an effort to select the pid automatically.
Figure 54 – Auxiliary RDS configuration
The Advanced UECP Site/Encoder Addressing choice enables access to UECP
data filtering settings. If the auxiliary/ancillary data only contains information about
one service this should not need to be used. If there is more than one radio service
signalled in the UECP data the following optional filtering elements can be specified to
obtain the correct RDS information.

Only enough information to uniquely identify a single set of service information is
required. If there is insufficient filtering information specified, the transmitted RDS
data will contain all unfiltered information. The effects of this on a receiver are
unspecified.
As a precaution we recommend that the RDS data transmission should be verified by
a test receiver if a complete filter specification is unavailable.
4.6.4 FM Radio Module-Controlled Input Handling Redundancy
Overview
FM radio module-controlled input handling redundancy refers to the process by which
the FM radio module can receive configuration from two different MMI boards, but not
at the same time.
The chassis will have two switches. One switch will be configured as the main switch
while the other switch will be configured to be the redundant switch.
There will be two FM radio modules, one for each switch. It must be noted that FM
radio module redundancy configuration is currently only supported for IP input
modules.
Hardware requirements
The following hardware is required for the implementation of FM radio modulecontrolled input handling redundancy:
2 IP input modules
The unit must be equipped with at least two IP input
modules
2 Switches
FM radio cards
For FM radio module-controlled input handling redundancy
to be implemented, switching configuration must be known
at set up. Therefore both IP input cards must have MMIs
(though one will be redundant). It should be noted that
both IP input modules do not need to have the same
configuration.
Alarms that cause switching:
FM radio module-controlled input handling redundancy will be implemented with the
following alarms:
No Data Input
An alarm that originates from the FM radio module when
no selected services are received.
No Contact with MMI
Board
The FM radio card periodically polls the MMI card. If a
certain number of polls fail contact with the MMI is
assumed lost.

Configuring modules for FM radio module-controlled input handling redundancy
through the user interface
FM radio module-controlled input handling redundancy is automatically implemented
by the FM radio modules and as such does not need configuration.
However, there is provision in the GUI to switch redundancy off.
Switching FM radio module-controlled input handling redundancy off is done through
the FM Radio tab in the navigation pane. From there, open the Redundancy tab in
the sub-tree - this will open the configuration page in the web GUI.
Figure 56 – FM radio module redundancy
General display
The configuration page lists the FM radio modules by location (i.e. slot number), and
whether it is enabled or not. The status is displayed, and can take the values of
either “logged in” or “off”. In addition, a “Switch” button is present.
Enabling redundancy
The “Enabled” check box must be selected to enable redundancy on the card.
The “Status” column displays whether the module in the slot is logged into the MMI
board or not. To enable FM radio module switching to occur, the status of the card
must be “logged in”. It should be noted that this occurs automatically when the FM
radio module is inserted.
Performing a manual switch (by operator through GUI)
The “Switch” button enables the operator to perform a manual switch from the GUI
Automatic backplane-switching at board boot time
The FM radio modules are designed to log into the first available MMI board. They will
always try to log in to the main MMI board first. If FM radio module-controlled input
handling redundancy is enabled, the FM radio module will try the backup if login fails
on the main. If FM radio module-controlled input handling redundancy is switched off,
they will only try to log into the main board.
Automatic switching
It is a non configurable hysteresis of 10 seconds from the switch criteria happening to
the actual switch.
SW Version 2.04

The total switch time depends on the configuration of the boards - It is 10 seconds
from the switch to the return of the sound on the radio receiver.
4.7 Configuring Transport Stream Outputs
The unit can be configured to host a number of different output modules. Select the
Outputs folder from the navigation pane to view all available output modules
showing key information about the current configuration for each card.
Figure 57 - Outputs view
The following information is available from the Outputs view:
Slot
slot position in the chassis
Type
type of output module
Services
the number of services assigned to the output module
Output Rate [Mbps]
the total data rate of all configured services. The rate shown
includes all overhead data such as IP headers.
The creation of an output transport stream is easily done from the outputs
configuration view present for each output card. Before an output can be created, the
input card(s) must be configured correctly such that the list of input services is
present. Then adding a service to an output is done via drag-and-drop from the list of
available inputs.
The unit supports two types of output streams, SPTS and MPTS. The difference
between the two is that the MPTS streams are always CBR streams while the SPTS
streams are the same as the input. Additionally the MPTS output has a better support
for PSI/SI compared to the SPTS output.
A configuration of an output will automatically cause the system to generate PSI/SI as
well as adding the service related PIDs to the output. The next paragraph gives a
detailed description of which PSI/SI tables are supported.
4.7.1 PSI Base Value Settings / Defaults
This equipment offers PSI/SI support. The tables shown below are supported by the
streamer. Other tables, as defined by the DVB standard, that are not shown below,
are not currently supported.

4.7.1.2
NorDig Logical Channel Descriptor Support
From the NorDig NorDig Rules of Operation.
“The logical_channel_descriptor is a privately defined descriptor (i.e. not DVB
specified) intended for use in cable, satellite and terrestrial networks. If used, this
descriptor shall be inserted in the second descriptor loop in NIT. The descriptor is used
to comply to the fact that some services are to the viewers related to a specific
channel position”.
The Logical Channel Descriptor (LCN) implementation in the SC2000 supports both
version 1 and version 2 of the LCN.
The LCN configuration is accessible via the edit field to the right of the NIT in the PSI
table’s base values dialog shown above. Press the edit field and the following dialog
will appear.
SW Version 2.04
30-January-2009
Page 73 of 128
For version 2 the SC2000 supports a single list only. For more details on the usage of
list please refer to the NorDig standard.
To add channel assignments it is possible to import all the outgoing services
automatically by pressing the “Import Local Services” button. Then all the services will
be listed and it is possible to edit the channel numbers directly. Alternatively it is
possible to press the Green “+” and insert manual all the required data for each
service. The annual insertion is required in order to include services generated in
other units.
The dialog shows a LCN with two services, the first one was detected via the “Import
Local Services” button while the other was added manually. The Service name is not
part of the LCN but is displayed for local services for convenience only.
To change an existing setup just change the channel number and press apply.
To remove an existing channel number entry, press the x symbol to the right of the
entry and press apply.
4.7.2 PSI Settings for Individual Outputs
In some scenarios, it is necessary to configure individual table settings. To configure
the individual settings, open the Enter Multiplex dialog. This is achieved by clicking
Outputs Æ IPAddÆMPTS. The dialog is shown below.
SW Version 2.04
30-January-2009
Page 74 of 128
Figure 59 - The Enter Multiplex dialog
In the PSI screen, fields for the Table Id, Table Type, Mode and Playout Rate are
displayed. One additional parameter is available compared to the PSI dialog shown for
the base value settings.
Use Base Value – this check box allows user to select if the base values should be
used, or if these values should be specified separately for this output. Check this box
to enable the generation and broadcast of that table type based on the global settings
described above. Uncheck the box to make local changes.
Click Apply to store the changes.
4.7.2.1
Service Order in MPTS PAT
The sorting algorithm for the service order in PAT for MPTS streams is relatively
simple. However in most cases this is not of that great interest. If a specific channel
line-up is required consider to add the NorDig Logic Channel Descriptor in NIT. This is
found in the PSI base value settings for the NIT.
The order of appearance is based on three values.
Input slot
Input port
Output service ID

4.7.3 Generation of IP-OUT SPTS Streams
A Single Program Transport Stream (SPTS) output is only supported by the IP output
card. The key difference between an SPTS and an MPTS is really the way the GUI
provides a simplified setup for the SPTS output, and that the SPTS does not allow to
configure the Network and TS id. For an SPTS output the Network ID is hardcoded to
8000 + slot id of the output card, and the TS ID is automatically selected from the
range 1-250. Hence the first SPTS output on an IP output card in slot 16 would
typically be NETWID=8016, TSID=1.
The following procedure shows how to create an SPTS.
Navigate to the Outputs folder, click on the IP module you want to configure and a
window similar to the one in Figure 60 will be displayed.
Figure 60 - IP SPTS output
Before assigning a service to the IP output some default parameters may be specified
such as the IP address, port number, etc. These settings can be found under the
Default Stream Properties heading. The following parameters can be configured by
the operator:
IP
Set the IP address of the SPTS
Port
Set the Port number

Scrambler
If a scrambler module is installed you can choose to
scramble the selected service by selecting one of the
available scramblers from the pull down menu
ECM
If scrambling has been selected, assign the output stream
to the appropriate scrambled subscriber package. Please
refer to chapter on scrambling to set up subscriber
packages.
MPEG Packets/Frame
Number of MPEG packets per UDP frame. Default is 7.
Type of Service
Specifies the Type-of-Service (TOS) value to prioritize
between Delay, Throughput and Reliability. Please refer to
the IP protocol specification for details.
Time to Live
Set the time-to-live (TTL) value defined for the IP
multicast protocol:
0
restricted to the same host
1
restricted to the same subnet
32
restricted to the same site
64
restricted to the same region

SPTS Enabled
Enable SPTS
RTP
Enable Real Time Protocol
EMM Passthrough
Forward CAT/EMM tables for service that are received
scrambled and not descrambled in the chassis.
Next, add an input service to the IP output. Under the Input Services heading you
will find all the available services. Just drag-and-drop the service you want to assign
to output over to the Output window and the service is assigned to the IP address
specified under Default Stream Properties. Please notice that the IP address under
the Default Stream Properties is incremented for every service you assign to the
output.
Add all required services to the IP output field (Output). Remember to adjust the
default parameters if required.

Service Properties
In order to change the settings for an assigned service just double-click the service
and the Service Properties for that service will be displayed (see above for
parameter details).
The Service tab displays the Service Name, Service Id, Monitor Port, and
Component Mode for PID Settings. The original Service Name can be enabled
using the checkbox, or the operator can configure their own by unchecking the
checkbox.
The Service Id can be configured.
The Monitor Port option is intended as a way to monitor a descrambled service by
configuring the system to send the descrambled stream to a decoder card within the
chassis. The stream sent to the decoder is an exact copy of the outgoing stream. The
packet copying is done on the descrambler card to ensure that the monitored stream
is identical to the outgoing one.
It is possible to change the PID Component Mode. Here the mode manual is added
compared to the default parameter list described above. In the manual mode it is
possible to select which PIDs to include. It is also possible to remap PIDs to a different
output value.
In the above example the pid filter is used to stop the ecm and three DVB Subtitling
pids. In the manual PID mapping mode the system will not handle dynamic changes
of the input pids. This implies that if the input has dynamic characteristics it is adviced
to use one of the automatic modes, (auto all, A/V, A/V/TTX), which will handle
dynamic input changes.

Port Settings
The Port Settings tab is used to change the IP specific parameters. The Output
Redundancy fields are to be used in a system configuration where two IP cards are
configured in a redundancy scenario. Please refer to “IP output redundancy chapter”
for details.
Default values for Rate, RTP, Source Port, Time to Live, Type of Service, MPEG
packets/Frame?
In addition to the port parameters explained for the default configuration explaned
above the following parameters may be configured for each output port.
CBR Mode
The Constant-Bit-Rate option enables an SPTS output to be
sent with constant bit rate. The user will need to provide the
desired output rate. If the service exceeds this rate, then the
system will report an output-buffer overflow alarm and drop
packets.
Source Port
The IP Source port of the output multicast. In a output
redundancy configuration this value will be replaced with the
virtual source address.
4.7.3.3
Port Settings - IP FEC Support
A new generation IP output card will support IP FEC. Except for a Larger FPGA chip
this card is identical to the standard IP output cards. Given this option is available the
Port configuration page will include the IP FEC configuration parameters.
SW Version 2.04

FEC Mode
Forward error correction (FEC) mechanism that can be used
to correct errors than can occur during the transport.
COP3 Level A: Use FEC Columns only. Protects against Burst
loss.
COP3 Level B: Use both FEC Columns and Rows. Provides
an additional protection against Random Packet Loss.
A FEC matrix is generated and transmitted on two separate
UDP ports:
FEC columns on UDP port + 2
FEC rows on UDP port + 4
The importance of this is that when FEC is enabled it is
important the UDP ports reserved for the FEC system is not
occupied by other traffic.

above specified point.
Note:
This option is available for selected customers only.
PVR Mode
This field should be used if the headers of the packets should
be left in the clear – typically used for trick mode applications.
EMM Passthrough
Used if an incoming service shall be transmitted with its
original CA without being descrambled in the unit, such that
receivers further down the chain can do the descrambling.

Available EMMs
A list of the EMMs that is received from a CA system over the
Simulcrypt protocol. Multiple EMMs may be added.
Available ECMs is a list of the predefined ECMs. Use this dialog to select which ECM to
use for the encryption. Multiple ECMs may be selected, but only if the ECMs is defined
with the SAME control word, i.e they are created with the same SCG_ID. When an
ECM is selected all ECMs not containing the same control word will be tagged red, and
will not be possible to select.
It is possible to reconfigure all parameters from the Default Service Properties as well
as adding a monitor port for monitoring the service (requires an available decoder
module to be present in the chassis). It is possible to stream and decode the same
service up to 4 times.
Save and activate the settings by pressing the Apply button at the bottom of the
page.
4.7.4 Generation of MPTS Streams
The streamer is capable of generating MPTS outputs. First step is to set the
Transport related parameters which is done in the Edit Multiplex dialog. The next
step is to add services to the MPTS. Adding services is drag and drop based.
An MPTS stream provides some more PSI options than SPTS, as well as it provides
the option to map through External PIDs which will not be signaled in the PSI.
The next paragraph describes how to create a Multiple Program Transport Stream
(MPTS) for an IP output card. This description is also applicable for the ASI output,
except the port settings dialog. Please refer to paragraph 4.7.4.2 “ASI Output” for a
description of the port settings, for all other parameters refer to the description of the
IP MPTS.
4.7.4.1
IP Output MPTS
Navigate to the Outputs folder in the navigation pane, click on the output module
you want to configure and a window similar to the one displayed in Figure 42 below
will be displayed.
Figure 62 - IP MPTS output
The check box to the left of the MPTS stream, on the right hand Output pane,
provides an easy way to stop the transmission of the output, without having to delete
the configuration of the MPTS.
Click the Add MPTS button to create a new MPTS stream. A new window will open
where the MPTS parameters can be entered.

PID
Input PID to be forwarded
Out PID
Input PID is mapped to this output PID number. Note that each output
PID occupies one channel through the output card like any other channel.
The maximum number of channels through the output card is 250.
The Port Settings tab is card-specific and will differ according to whether it is for an
IP or an ASI output card. For the IP output card the following dialog yields.
This dialog is identical to the one for the IP SPTS configuration. Please refer to the
SPTS configuration description for details.
The CA Settings
In MPTS mode it is possible to add EMM streams from the connected CA system. Add
the desired EMM(s) and click Apply.
SW Version 2.04
30-January-2009
Page 84 of 128
The PSI Settings
The PSI tab allows the base values earlier defined to be overwritten for each specific
output stream. The list of the tables displays the currently selected mode. To change
uncheck the base value check box and change the new mode as desired. Note that if
this change is applicable to all outputs it is cleaner and easier to cheng it from the PSI
navigation tree where the base values are configured. A change in the base values will
automatically be updated to all the outputs using them.
In order to add services to the Multiplex just created, just drag and drop services from
the Input pane to the output pane.
As for the IP SPTS mode it is possible to edit a service which has been added to an
MPTS. To edit expand the MPTS node on the right hand pane of the output window.
The following dialog will appear.
The service dialog allows for the change of both service name and service ID. These
changes will be reflected in the SDT and PMT respectively. For the other parameters
please refer to the IP SPTS configuration description.
The CA settings tab is similar to the one of the SPTS configuration. Note that the
EMM configuration is not available in this dialog as is the case for the SPTS setup. For
MPTS’s the EMM is entered on transport level.
SW Version 2.04

4.7.4.2
ASI Output
The ASI output card can output up to 4 separate MPTS’s. The ASI output
configuration is similar to the configuration of an IP MPTS output, except that the Port
Settings tab in the Multiplex dialog is different. For a description on all parameters
except the Port Settings please refer to paragraph 4.7.4 “Generation of MPTS
Streams”.
The configuration of an ASI output port consist of first defining port specific setting
such as total bite rate, whether the port shall be enabled or not etc. This setup is done
in the Edit Multiplex dialog. This dialog is activated by double-clicking on the
respective port on the ASI output card. The next step is to configure the services to
be mapped to this port. This service setup is drag and drop based.
The following procedure shows how to configure ASI Output Port Settings
Navigate to the Outputs folder, click on the ASI module you want to configure and a
window similar to the one in Figure 64 will be displayed.
Figure 64 - ASI output
The check box to the left of the 4 ports in the Output pane on the right hand side
enables/disables each respective port.
To change port specific parameters double-click on the Port node on the right hand
pane to open the dialog shown below.
SW Version 2.04
30-January-2009
Page 86 of 128
This dialog is like the Edit Multiplex dialog in the IP out card except that the ASI
settings field has replaced IP settings field. The ASI parameters are:
Rate [Mbps]
The total ASI output rate. The stream will be stuffed with NULL
packets to maintain the correct fixed bitrate.
Packet Size
The TS packet size (188/204)
Byte Mode
The byte mode specifies how the TS data is transported over the ASI
link.
Burst/Byte Mode
In burst mode all the TS-data-bytes are sent without any idle symbols in between. In
spread mode the ASI specification requires at least one idle byte between each databyte, and that each packet start indicator (0x47) is preceded with at least two idle
bytes. The ASI output stream in spread mode guarantees that each data-byte is
preceded with two idle symbols. This effectively reduces the maximum data rate to
1/3 of the maximum ASI output rate, i.e. (213/3) Mbps. If higher rates are required
use burst mode.
4.7.4.3
QAM Output
The QAM output card can output up to 8 separate MPTS’s. The QAM output
configuration is similar to the configuration of an IP MPTS output, except that the Port
Settings tab in the Multiplex dialog is different. For a description on all parameters
except the Port Settings please refer to paragraph 4.7.4 “Generation of MPTS
Streams.
Although the QAM output has one physical plug it carries up to 8 transport-streams.
Internally these streams are modulated by two QAM modulators (see figure in chapter
3.4.3). The configuration of the QAM modulator parameters has been put into a
separate node in the navigation tree below the QAM output, called Device Setup.
SW Version 2.04
30-January-2009
Page 87 of 128
When the Device Setup is selected both the modulators can be configured from the
dialog that appears.
The QAM symblorate and RF level is applicable to both modulators; while the other
parameters may be configured individually for each internal modulator. Change the
values and press Apply to activate the changes.
The Frequency may only be tuned for the first carrier of the modulator; the remaining
three will automatically be tuned as an offset from the first, with the channel spacing
specified by the user.

4.7.4.4
NIT Generation for QAM Networks
The SC2000 is able to generate the NIT including Cable Delivery System Descriptor
for QAM networks. The Cable Delivery System descriptor is defined as part of the
MPTS setup, and the inserted data will be included in the NIT. The fact that the Cable
Delivery descriptor is added in the MPTS node it implies that this descriptor may be
added not only for the QAM output module, but also for the IP MPTS output and ASI
output for streams which will eventually be part of a QAM network.
For an IP output this is possible by adding MPTS nodes, and inserting the QAM
parameters which for the relevant transport streams which then will be added to the
NIT.
For the QAM output the virtual QAM output provides this feature. The virtual output
may be added from the QAM output page (top right in the picture below.)
In the dialog that appears, insert the Network ID, Transport ID and the QAM
information.
Then press Apply.
4.7.4.5
MPTS Transparent Mode
With MPTS Transparent Mode, an input stream is forwarded to the output without any
processing, i.e. output equals input, including null packets (for ASI and QAM, which
are CBR, null packets will be added).
SW Version 2.04
30-January-2009
Page 89 of 128
When setting up a transparent stream, the “Add MPTS” button is not used. As with an
SPTS, one simply drags an MPTS from the list of available MPTS’s over to the output
pane. In the output pane, the name of a stream will indicate if it is transparent.
For IP Output, one can configure Port Settings. This is as described for SPTS in
4.7.3. For ASI and QAM, make sure to configure sufficient bit rate to transport the
inputs payload and null packets. If packets have to be dropped, it is unpredictable
whether this will be done to payload or null packets.
4.7.5 IP Output Redundancy
The IP output redundancy functionality makes it possible to have multiple units with
IP output cards multicasting the same services, and letting the network handle data
loss.
A service may not reach the destination STB for a number of reasons: The source unit
may have an input rate of zero, a descrambling failure, a missing input or output
card, or an error in path to the STB. By adding one or more redundant units with IP
output cards service outage may be prevented given the error is a isolated error.

Overview
The IP output card sends the services out as IP multicasts, and relies on OSPF and
PIM messages to configure the network. The routers use this information to route the
multicasts. The network will automatically detect the presence of more than one route
and the redundant packets are thrown away by the routers before they reach the
STBs.
A typical scenario is to broadcast a Digital TV service from two locations using the
same multicast destination address. The network is designed to route one copy only
of the multicast stream to the receiver. In case a source failure occurs, with IP output
SW Version 2.04
30-January-2009

redundancy implemented, the network should automatically switch to the spare
source.
In order for the network to understand that two multicasts are the same, both the
source and destinations IP address need to be the identical. This is important and
must be taken care of during configuration of the unit.
4.7.5.2
Multicast Configuration
Each subnet must have a designated PIM router (PIM DR). By default, the router is
the DR. But when output redundancy is enabled, the IP output card takes over the
role as the sub network’s DR. All multicasts with different IP addresses than the
multicasts from the IP output cards are stopped by the router. Hence, all IP output
cards must have a separate subnet.
The configuration of these source addresses is a two step process. The first step is to
define which network subnet to use as the source address. The second step is to
specify the unique source for the actual multicast.
4.7.5.3
OSPF Configuration
4.7.5.4
Defining the Source Subnet
OSPF is used to configure the routers. The routing decision is made on every step in
the path. The choice is based on the metric. The metric is based on the number of
hops taken and the cost added manually. The redundancy scheme does currently not
support any other routing protocols.
In the context of IP output redundancy the source subnet refers to the network
segment which is to be used as the source network. This network needs to be the
same for both output cards, which shall be configured as redundant to each other.
The source subnet is a network parameter that is applicable to each output card.
Therefore it is configured as part of the IP address setup for each output card on the
ipout page. Go to the Admin node in the navigation tree and click on the IP output
card to be configured. This will open the ipout page displayed in Figure 51 below.

4.7.5.5
Defining the OSPF Area
One of the most important features of OSPF is the concept of an Area. An OSPF
network can be broken up into areas that are connected by Area Border Routers
(ABR). Routing information can then be summarized at the ABR before being passed
along to the next area. This means that routers in one area don't need to worry about
the LSA information from routers in other areas, which drastically improves network
stability and convergence times, as well as reducing the amount of resources required
to support OSPF on the routers.
For OSPF to work well, you need to allocate your IP addresses appropriately among
the Areas. In particular, you want to be able to summarize the routes for an Area
when you pass this information along to the next Area. The summarization doesn't
need to reduce perfectly to a single route for each Area. But the fewer LSAs you need
to pass between Areas, the better OSPF will scale.
Each Area has a 32-bit identifier number, which is often represented in dotted decimal
notation, similar to IP addresses. Every OSPF network should have an Area 0 (or
0.0.0.0), and every ABR must be a member of Area 0. This enforces a hierarchical
design model for OSPF networks. The one exception to this rule happens in a network
with only one Area. In this case, you can actually give this Area any number, we
recommend using an Area 0.
4.7.5.6
Defining the RP Point
In IGMP-v2 networks you will have to enable PIM and set a RP Point, disable PIM on
networks using IGMP-v3.
An RP is a router somewhere in the network that acts as a central distribution point
for one or more multicast groups. When the last-hop router receives an IGMP-v2
message from a device asking to join a group, it has to go looking for that group. The
best place to start looking is the RP.
4.7.5.7
MD5 Authentication
You may want to authenticate your OSPF neighbor relationships to ensure that no
unauthorized equipment is allowed to affect routing.
SW Version 2.04
30-January-2009
Page 92 of 128
The cryptographic method uses the open standard MD5 (Message Digest type 5)
encryption standard. MD5 is a one-way irreversible cipher. Two devices exchange only
the MD5-encrypted versions of the password. Both devices know the same password.
Each router is able to verify that the encrypted password that it receives is correct by
using the same algorithm to encrypt the password that it already knows. To make
sure that nobody can just intercept and use the encrypted version of the password
directly, a time value that the receiving router also knows is added to the password
before encrypting. Anybody else listening on the network is only able to see the
encrypted version of the password, but they cannot deduce the original password.
If you use authentication in an OSPF area, you must configure all of the routers in the
area to support authentication. Every interface on a router doesn't have to be
configured with authentication. But if you require authentication in any part of an
area, you must include authentication support throughout the area.
4.7.5.8
Defining the Source IP Address
The source address must be in the same subnet as the Source net defined above. The
actual address is defined as part of the configuration of the IP output multicast (SPTS
or MPTS). To open the configuration page, click OutputsÆIP
In the configuration dialog it is possible to define the last digit in the network address,
which together with the source network gives the complete source IP address.
Then click Add MPTS Æ Port Settings and tick the Output Redundancy check box
to enable output redundancy

5.1.5 Alarm Filter
The alarm module provides filtering based on slot, port and alarm ID. If an
incoming alarm does not pass the filter the alarm is discarded, i.e. it is not shown in
the active alarms view; it is not recorded in the alarm history and not indicated on the
LED on the module.
To define an alarm filter, go to the Alarm Filter page.
Figure 70 - Alarm filter
The alarm filter page lists all the relevant alarms for the card type selected (if no
specific card is selected all alarms are listed). When an alarm filter is removed any
active alarms which are filtered will re-appear with the timestamp according to when
the filter was removed.
SW Version 2.04
30-January-2009
Page 98 of 128
Note:
The filter also applies for the SNMP trap system.
Note that the alarms shown in the alarm drop down list are all the alarms that are
registered by each module in the system. A module is most often represented by a
card. From the above list the SCR module equals a scrambler card. When an alarm is
raised by the respective module detecting an error condition it is possible for the
module reporting the alarm to override the alarm description, in order to add some
extra info. This may in some cases cause the alarm text displayed in the alarm filter
list not to match the actual alarm text, but it should be obvious which alarm it is.
Figure 52 and Figure 53 list the alarms for the SCS cards Channel Errors alarm.
During boot the SCS card registers a general ECMG Channel Error alarm. This alarm is
visible in the filter list as shown below. Then when the card detects a problem with
the channel the alarm is triggered, with some additional information conveyed in the
alarm description, in this case the channel error is no connection with the CA system.

5.2 SNMP
5.2.1 Overview:
The SNMP agent is located on the MMI module, and uses the same IP address. A
number of variables can be configured, including the SNMP configuration file
(containing the public and private community strings, for user access and alarms);
and the trap destination table. This is explained below.
5.2.2 Configuring Public and Private Community Strings:
The SNMP agent supports changing the read and write community strings for
incoming requests and outgoing traps. The incoming community strings are defined in
the configuration file for the SNMP system located on the MMI card.
SNMP configuration file: /etc/snmp/snmp.conf

DO NOT CHANGE
When the snmp.conf is changed the SNMP daemon must be restarted in order for the
changes to take effect. To do this change to superuser and do:
stop atvsnmpd
start atvsnmpd
The SNMP agent uses the same IP address as the MMI. All alarms are forwarded as
SNMP traps. The Appear TV sub tree in the MIB contains a table with the trap
destinations where traps are sent, a table of active alarms, and the sequence
numbers of the newest, oldest and maximum possible active alarms.
5.2.3 Configuration of the Trap Destination Table
The trap destination table must be edited to receive traps. It has five entries, hence
allowing five different trap destinations to be used at the same time. Additional rows
cannot be created. The tdIpAddr field contains the IP address of the NMS, while the
tdRowStatus field is used to determine whether traps should be forwarded. To
enable traps towards a specified address the corresponding tdRowStatus field must
be set to active (1). To disable traps, set the tdRowStatus field to notInUse (2).
Errors are reported when trying to send traffic towards IP address 0.0.0.0, which is
the default IP address.
5.2.4 Interpretation of Traps
Each trap is uniquely identified with the combination of msgId, msgSlot, msgPort,
and msgInstance fields. The type of error is specified with the msgId field, while
the location is specified with the rest, where the msgSlot field is the slot, msgPort is
the port on the slot, while the msgInstance field is used when further differentiation
is necessary.
The other fields correspond to the fields in the GUI: the msgSeverity field to Level,
the msgSourceName field to Application, the msgText field to Error Code, and the
msgGenerationTime field to Set.
5.2.5 Worked Example on SNMP Usage
To test the SNMP implementation with net-SNMP, install the mibs in the mibs
directory. This directory may be "/usr/share/snmp/mibs", depending on the
installation.
To browse the entire mib tree for the mmi on IP address <src ip address> (note the
dot at the end of the line):
snmpwalk -m ALL -v 2c -c public <src ip address> .
To only browse the subtree:
SW Version 2.04
30-January-2009
Page 100 of 128
snmpwalk -m ALL -v 2c -c public <src ip address> appeartv
To send traps to ip address <dest ip address> First set the trap destination address:
snmpset -c private -m ALL -v 2c <src ip address> APPEARTV-TRAPDESTINATIONMIB::tdIpAddr.1 a <dest ip address>
Then set the community string may be changed if needed to <new community
string>:
snmpset -c private -m ALL -v 2c <src ip address> APPEARTV-TRAPDESTINATIONMIB::tdCommunityString.1 s <new community string>
Finally the entry must be activated with:
snmpset c private m ALL v 2c <src ip address> APPEARTV-TRAPDESTINATIONMIB::tdRowStatus.1 i 1
To send the traps to stderr without forking the shell:
snmptrapd m ALL f Le
5.3 Soap XML Interface
The Soap XML interface can be used for external control and monitoring of the unit.

6 Maintenance
This chapter describes how to perform maintenance tasks such as software upgrades,
replacing faulty modules, etc.
6.1 Software Upgrades
Software can be uploaded to the unit remotely using the Maintenance Center (MC).
Please refer to the MC users manual for details.
Required software upgrades for units the will be provided together with instructions
by.
6.2 Configuration Back-up System
The ASIO-based software platform enables automatic backup of the service
configuration. It consists of a Linux cron job set to run every night at 04:00. A history
of 4 copies will be preserved before the system starts to override backup files. The
script looks for other ASIO cards, and exports the database to a text file and copies it
to the remote cards found. In case the backup is needed there is a script provided to
retrieve the backup. This script will erase the current configuration and create a new
database with the exported data.
Note:
A module reboot is necessary for the new configuration to be activated – this is
automatically done by the “restore” script.
Some useful commands
atvdbsnapshot dist
dumps the live configuration to file on a
remote card within the unit
atvsdbsnapshot restore <database>
restores the earlier files dumped to the
remote card. For ex:ample:
atvsdbsnapshot restore atvconfig.db
6.3 Configuration backup guidelines
Although the internal backup system will automatically back up the configuration
database it is good practice to keep a copy of the database somewhere externally to
the unit, the more importantly so the larger the configuration.
To make an external backup of the configuration please refer to section 6.6
If the external copy is to be used it is necessary to stop the application process on the
card before the configuration database may be copied. To do this log into the MMI
board using telnet or SSH. Then type
stop asio
Check that the processes are stopped
ftp atvconfig.db to /etc/atv/atvconfig.db
(If this fails, stop the boa server, it may occupy the database.)
SW Version 2.04
30-January-2009
Page 102 of 128
reboot
Reboots the card to activate the new configuration
6.4 Hot-Swapping
The platform supports module hot-swapping, i.e. the different modules (the decoder
modules, the input module and the switch-module) can be replaced during operation.
Removing a module and replacing it with a new one will not cause any damage to the
module. Hot-swapping a module will only directly affect the signal through the
relevant module. The direct and indirect effects of a module hot-swap are explained in
detail in the sections below.
6.4.1 Performing a Hot-Swap
A module is removed by first loosening the screws on the top and bottom of the
module (one is located in the ejector). This is followed by pressing the white button
inside the card ejector and pushing the ejector down. This will release the module
from the chassis.
When inserting the new module into the chassis it is important to align the module’s
edges with the module-guides in the chassis. Make sure the jack on the module is in
open position as illustrated in Figure 73. Slide the module into the unit on the moduleguides until the jack touches the chassis. Move the jack upwards. This will insert the
module all the way into the unit.
Figure 73 - Module jack in open position
6.4.2 Input Module Hot-swap
Support for the hot-swapping of all input modules allows modules to be replaced
during normal operation only affecting the services related to the relevant modules.
The unit will automatically re-configure the new input module with identical values to
the board that has been replaced.
One of the available input modules will always be configured as the Man Machine
Interface (MMI). This module manages all the other modules in the unit and stores all
configuration information in a database. Replacing the input module with the MMI will
cause all services to stop. Hence replacement of the MMI board must be performed
with care, and a full backup of the configuration database is recommended.
SW Version 2.04
30-January-2009
Page 103 of 128
6.4.3 Switch Module Hot-swap
All communications between different modules in unit are facilitated by the switchmodule. Removing this module will disable all backplane communication. The effect of
this is loss of all services. The color of the status LED on the modules will change to
blue. Once a replacement switch card is inserted into the device the LED changes
back to red/green and the services resume automatically. No configuration of the
switch module is required.
6.4.4 Decoder Module Hot-swap
Decoder modules can be replaced during normal operation only affecting the relevant
modules with minimum disruption of services. The unit will automatically re-configure
the new module with identical values to the module that has been replaced. The
module will therefore automatically start decoding the same service which was
decoded previously.
NOTE:
It is important to insert the new decoder module in the same slot as the
decoder module it is replacing and that the new decoder module has the same
configuration (same options).
6.4.5 Output Module Hot-swap
Output modules can be replaced during normal operation only affecting the services
related to the relevant modules. The unit will automatically re-configure the new
output module with identical values to the board that has been replaced.
6.5 Adding / Replacing /Removing Modules
Before upgrading a unit with additional channels, please check that there is sufficient
space in the chassis to support the additional module(s).
The left-most slot seen from the front (slot 0) can only hold the switch card, while the
right-most slot (slot 17) contains power connectors only designed for multiple slot
modules, i.e. it may not be used for single slot modules.
Before inserting a new module into the chassis, please remove the required front
plates. With a screwdriver open the air vents in the bottom of the chassis as
illustrated in Figure 74. Each air vent is opened by pushing down on the left side (as
seen from the front). Each air vent should be opened 90 degrees. Make sure that the
air vents both in the front and in the back of the unit are open for each module in use.
Please make sure the air vents on both side of a module guide is open. For decoder
modules which are 2 slots wide, air vents in two slots must be opened. For decoder
modules which are 3 slots wide, air vents in three slots must be opened.
SW Version 2.04
30-January-2009
Page 104 of 128
Figure 74 - Opening of air vents
When all the new modules have been inserted into the chassis, please make sure that
the front is completely closed using front panels. Leaving a slot position open without
a module or front panel will cause the unit to draw false air and consequently could
result in over-heating of the modules in the chassis.
To permanently remove modules from a specific slot position, the modules should first
be removed from the chassis. Next, select the About folder in the navigation tree. All
missing modules will be shown as red. To permanently remove the configuration of
the module from the chassis, select Accept Changes. This will permanently remove
the missing modules from the database.
When replacing an existing card, please note that a module configuration always
follows the slot position and not the module itself. Consequently, if a module is moved
from one slot in the chassis to a new slot, the unit will report the original slot position
as hardware missing, while the new slot position will be configured as a new card with
default configuration. Hence if a card is to be replaced it is important that the same
slot is re-used for the replaced card.
6.6 Configuration Import and Export
The configuration of a unit can be saved to file for later retrieval. The file contains the
entire configuration, except the MMI IP address. Right click on ‘Save to file’ to save
the current configuration.
To retrieve the configuration from a file, select the file, mark ‘Include Data Port IP
Addresses’ if the data port IP addresses should be included, and press ‘Restore’.
SW Version 2.04
30-January-2009
Page 105 of 128
Figure 75 - Saving and restoring configuration
The two main purposes for exporting and importing configurations are to bring a unit
back to a previous state, and to use the same setup on multiple boxes.
The ‘Include Data Port IP Addresses’ option should be used if a unit should be brought
back to a previous state when lots of changes need to be undone, or if a upgrade has
been unsuccessful. The configuration ought to be stored before each upgrade, and
restored after a downgrade if the upgrade was unsuccessful.
The ‘Include Data Port IP Addresses’ option should be unchecked if the same
configuration should be used on different decoders. This way only one decoder needs
to be configured, and all the other boxes should use the same configuration.
6.7 Restoring the Default IP Address
It is possible to restore to the factory-configured IP address on the MMI module. This
can be useful if the software-configured IP address is lost. The restore is done by
setting a jumper on the two pins identified in Figure 76 or in Figure 77 depending on
which module the MMI is installed. Please note that your PCB layout can be slightly
different. When the jumper has been added, the MMI will be configured according to
the tables below regardless of what is stored in memory.
The default IP settings are:
IP Address
192.168.1.100
Subnet Mask
255.255.255.0
Default Gateway
192.168.1.1
VLAN
turned off
After connecting the jumper, the MMI card has to be rebooted. The factory default IP
settings will be active as long as the jumper is connected. While the jumper is
inserted, all IP parameters in memory can be changed and saved via the web
interface. Once the jumper is removed and the card is rebooted, the IP settings in
memory will be activated.

7 Troubleshooting
The following chapter provides hints and advice to the most commonly know issues
an operator may experience when operating the unit.
7.1 Unable to Connect to Device
Check the LED on the Ethernet port of the input module. If there is activity it will be
blinking. If there is no activity on the LED it means the input module has no
connection to the network. Try to connect to the unit from a PC as explained in
section 4.1.1 (use the IP address that was set during the initial configuration). If the
unit responds, it indicates the problem is a network problem. Try a new Ethernet
cable and troubleshoot the network.
If the unit is unresponsive but there is LED activity, check IP settings by restoring
default IP settings as described in 6.7.
7.2 Missing Video/Audio Output From a Decoder
Module
The status LED on the DDM front panel provides information about whether the
module has active alarms. If the LED is red, consult the web interface for detailed
error messages. The error messages will provide more information about why the
DDM card is not operating properly.
If the status LED is green, there might be issues with the configuration of the
module. Verify that the input stream is set up correctly. Access the inputs list as
described in section 4.2. Ensure there is incoming data on the input stream which is
serving the decoder module in question. If the bit-rate entry in the list reports 0
Mbps there is no data in the input stream and it is necessary to examine the stream
source.
Verify that correct service has been configured for the decoder.
Check all cabling. Make sure it is not damaged.
7.3 Missing Video/Audio Outputs From All Output
Modules
Verify that the device is connected to the network as described in section 7.1. If the
unit is connected to the network, check whether the status LEDs on the modules are
all blue. If they are all blue, it may be that the switch module is experiencing
difficulties. Try rebooting the unit. If all the status LEDs remains blue after the
reboot, the switch module needs to be replaced.
If the status LEDs are all green, use the web interface to check that input and
outputs are configured properly.
Check all cabling. Make sure it is not damaged.
SW Version 2.04

Page 108 of 128
7.4 No Audio but Video Present
Verify that the correct audio language is selected in the configuration page as
discussed in section 4.5.2. If the audio is configured correctly, check the alarm LED
and the status page in the web interface. If the module has problems decoding the
audio it will be reported here.
7.5 Unable to Descramble a Service
Please make sure you have inserted the CA-module correctly into the common
interface slot. Also make sure the smart card is properly inserted and capable of
descrambling the service in question. Please follow the procedure below:
Make sure your smart card has been updated with the necessary entitlements.
Please refer to section 4.4.2 for details on how to read smartcard info. Alternatively
Contact your CA provider for further instructions on how to do this.
Given the access criteria’s are correct it may be necessary restart the CAM or the
descrambler/Decoder board itself. The CAM may be rest from the GUI, while the
board may be reset from the Maintenance Center (see separate users manual for
details).
After a reset of the board or CAM pleas wait for approximately 15 seconds and check
if your problem still exists.
Pull out the complete decoder module and re-insert it. Allow a few seconds for it to
boot up again.
Contact the CA supplier for further assistance

QAM channel restarted,

Alarm Level
CRITICAL
Description
The QAM module does not manage to synch properly to the
signal received from the internal IP-output card. This causes
the QAM module to restart the channel.
The reason could be either:
1)
No services are configured, such that only NULL packets are
sent to the QAM, hence the QAM does not find a PCR.
2)
The PCR that it receives is too jittery – which may happen
when the services being sent to the modulator has been
descrambled from an IPIN MPTS. If this is the case try to use
the Alt CAM descrambling mode for the services being
descrambled
