Day to day Contingencies
ADC Main Failure
1. Turn automation off in Dashboard and switch to VTR (backup promo) in case commercial is
on-air or switch manually to PCR PGM if live content is on-air.
2. Switch ADC toggle switch to backup.
3. Save playlists in main air-client and close.
4. Open backup air-client application and append playlist and normalize operation.
Nexio Main Failure
1. Switching to backup server happens automatically within 2 secs. If not do it manually by
clicking the “PROTECT’ button on the air-client.
2. Check the server out, if needed restart the nexio device and start Nexio application.
Important:- if the nexio device is being restarted it will affect multiple channels so the same
process needs to be followed for corresponding channels.
Main MC-1/16x4 router failure
1. For Tamil, Malayalam, NE, Gujarati, Bangla, Kannada (BKP MC-1 present) channels switch to
B-chain through DSS.
2. Take the current on-air source (live/server) manually through Dashboard and then on the
playlist select B channel. (Logo and ticker on air through BKP MC-1)
3. For PHH, Oriya, Urdu (BKP MDK-111 present) channels switch to the B-chain through DSS.
4. Route the current on-air source through the router panel and then on playlist select B
channel. (Logo and ticker on air through MDK-111)
5. For UP/UK, MP/CG, Bihar/Jharkhand, Rajasthan channels, the PCR will key the logo and ticker
and also switch between commercials and live content.
6. MCR will switch to B-Chain through DSS.
DSS card (A/B switch) Failure
First input of the card is pass-through but before removing the card, the output of MC-1
needs to be hard patched to water mark input.
Ticker failure
1. If main ticker fails take backup ticker from Dashboard.
2. When backup ticker is on air, following elements will not be available (commercial bugs,
commercial astons, L bands)
Leased lines failure
If both leased lines are down at the same time, MCR needs to play the backup content and
contact the branch/feedroom to provide the backup source (RTMP, WOWZA, LIVEU, DSNG)
Total Power Failure in MCR
1. TX VTR is from a separate power source, so it can play the backup content and it needs to be
patched to watermark input for transmission.
2. Teleport needs to be informed to be ready to play standby content in case of total blackout.
Riedel Failure
1. Hotline to be used for communication between MCR and PCR.
2. Hotline to be used between desk and PCR.
3. RTS to be used for communication between feedroom and PCR
4. RTS to be used for communication between PCR and anchor
Shifting to Common PCR (in case of power failure in one PCR)
1. Viz content pilot, inews needs to be called to common PCR.
2. TP (samwad) needs be used by copying the script manually.
3. Airspeed needs to be hard-patched to common PCR airspeed.
4. Router tie-lines for common PCR are separate and can be used immediately.
5. Audio video sources (Studio camera, breaking news PC, anchor mic, aux for anchor EP) needs
to be hard patched to common PCR from CAR.


Failure of Switcher/Audio Mixer in one PCR
1. The first option can be to shift to common PCR as in case of power failure. All the procedures
as in case of power failure to be followed.
2. Second option can be to physically shift the failed device from common PCR to the
corresponding PCR. Physical connections need to be done.
PCR PGM MUX failure
PCR clean is available on the router. It can be taken on air by MCR and PCR will change the
output from clean to PGM through switcher panel.
Studio Power failure
1. Shift to common studio (camera output from common studio to PCR to be patched).
2. Anchor command from Riedel to common studio.
3. Audio output of common PCR to be patched into PCR audio mixer input.
SPG failure
1. SPG 8000 main fails then ECO 8000 will take input automatically from backup SPG 8000 and
distribute in the chain.
2. If automatic changeover does not happen, it can be done manually from front panel.
3. If the whole chain fails, we need to generate sync using a standby sync generator and
distribute in the existing chain.
Station/Feed Router failure
There is no backup for station router or feed router. The only option is to hard patch sources
and destinations through patch panel.
Power failure of feedroom
1. All the equipment are on dual source and single input equipment are on ATS. Even then if
there is a failure, the following points need to be taken care of.
2. Transmission of Tamil, Malayalam, NE, Bangla, Kannada, PHH channels is from feedroom
racks, so the first step is to ensure backup content from the teleport on these channels.
3. Restoration of power and services to be done by arranging alternate power from newsroom
power sources to these equipment.
Transmission rack-1
Network racks
Remaining baseband racks and workstations
Uplink from a location fails
Feedroom needs to arrange backup source (RTMP, WOWZA, LIVEU, DSNG) and route it
to MCR.
ILL failure
Out of 10 Servers, 5 connected in Power grid ILL & 5 in Airtel.
In case of Hardware/ILL Service failed, we can utilise existing servers by changing IP Address
of alternate ILL Service.
We can receive LiveU sources by connecting at other branches in case of both ILL down and
hardware failure.
Failure of Ingest Ports
On priority basis, we can ingest the important signals in other branches and get the feeds
through FTP in RFC common storage.
RF Failure (Dish antenna or RF cable issues) at RFC for DSNG at RFC
We can lock the DSNG source at other branch feed rooms and get the signal through Leased
lines & WOWZA/RTMP.
Failure of ANI & ANI Live select hardware/incoming Leased line
We can get both sources through ETT-Noida & CNBC Mumbai through NLD leased lines and
distribute to branches.
Distribution of ANI and ANI LIVE select to Major Branches (Presently through multi-cast)
1. If multicast fails, due to hardware failure we can use the standby encoder.
2.
If there is a leased line problem we can route the ANI signal to branches through
RTMP/WOWZA.
Counting Day Contingencies
MCR
Common for all channels
Any RFC PCR fails


If PCR output fails than RUT PCR output to taken through Router from MCR.
After resolving the problem (either move to common PCR or normalise the error) get back to normal
operations.
Main Ticker fails

Hard patch the backup common ticker into the relevant chain. When backup ticker is on-air we will
not get commercial bugs.
Channel Specific Plans
Oriya/Urdu/PHH

FEED ROOM
RUT set uplink to ETT



Total 3 IP encoders are being planned (1 existing + 2 additional) for uplink of RUT feeds to ETT. These
are as follows
o 3 cam switched output (embedded audio)
o Single cam output (embedded audio)
o Standby for (a) and (b)
In case of total NLD failure we can send both set outputs to ETT via wowza/RTMP.
In case of failure of both ILL and NLD we will have one Ku band DSNG and one C band DSNG as the last
backup.
Failure of feed router





For ETT feeds, output of ETT RUT-1 (3 cam switched out) needs to be patched into ETT encoder 1,
output of ETT RUT-2 (Single cam out) needs to be patched to ETT encoder 2, output of ETT decoder
(return signal from ETT) needs to be patched into SP-2 monitoring line.
For ANI 1 multicast, we need to take the DVDA output and patch it directly to ANI RTMP system, the
branches can receive ANI 1 through RTMP. RFC PCRs have ANI directly in their switchers and mixers.
LiveU and DSNGs to RFC PCRs: we can dedicate 2 LU server ports and one RF decoder per PCR and
patch these to the switcher DMUX inputs.
Critical feeds will be ingested at the branches and they can be shared with RFC via FTP.
ENG-1 and ENG-2 from SP-2 will be hard patched to wowza inputs to be available to branches.
