THE FCC AND
The FCC output requirements will come into effect on June 1, 2015. The requirements are
designed to enable connectivity with the multitude of IP devices in consumers’ homes and
comply with an open industry standard.
The FCC has determined that…
– DLNA produces open industry standards
– VidiPath meets the output requirements that come into
effect on June 1, 2015.

of additional boxes,
cords, remotes and
other service provider
specific devices.
VidiPath clients will work
with the billions of DLNA
Certified devices on the
market today.
Enables a consistent
service provider user
interface across
devices.
The VidiPath logo helps
consumers purchase
devices that access service
provider content

DTCP-IP: Protecting Streaming Content
•
•
•
•
•
•
Under this reliable technology content can be shared securely between products in a consumer’s home and not
accessible by third parties outside the consumer’s home network.
DTCP-IP is automatically negotiated between DLNA Certified Protected Streaming products and has been designed
to protect content as it moves across the local home network.
Legal protection provided by chain of licensing where DTCP-IP license mandates robustness (tamper resistant
enclosures, no clear text on user-accessible buses, buried traces, secure key storage, tamper resistant software for
host/client software).
Licensing that perpetuates protection on all home network devices and links together a chain of protection
technologies that permits a variety of marketplace technologies that support current and future content delivery
business models.
Utilizes well known/standard cryptographic algorithms which provides the following functionality:
– Authenticated Key Exchange (AKE)
– Mutual authentication using public key crypto
– Advanced Encryption Standard (AES)
– Copy Control Information (CCI) integrated
– Revocation (SRM)
– Strong license provisions
Motion picture studio support with three studios as “content participants” and others relying on DTLA’s “IP
Statement” to require use of DTCP-IP through their content licenses.

DLNA HTTP ADAPTIVE DELIVERY: MPEG-DASH
•

•
Extensibility of DLNA HTTP streaming to deliver adaptive and dynamic multimedia content by
dynamically requesting different “representations” of the same content item from a server.
Client adapts to varying access and streaming channel conditions to dynamically select suitable
representation for the best viewing experience.
Based on MPEG DASH ISO Live, ISO On Demand, and MPEG2-TS Simple profiles.
Other Organizations adopting MPEG DASH: 3GPP, OIPF, HbbTV, DECE, DTG, W3C.
Added MPEG-DASH Media Format Profiles:
– In addition to MPEG2, H.264, etc.
– ISO base file format and MPEG2 TS
– Common set of codecs: AVC, AAC
Dynamic Adaptive Content is identified by new DLNA Media Profile – DASH_MPD, describing MPEG
DASH Media Presentation Document (MPD).
Transparent support for DLNA Link Protection (DTCP-IP).

AUTHENTICATION: VERIFYING
Service Providers
CERTIFICATION
Are you really a
VidiPath client?
Are you really a
VidiPath server?
Both client and server (in-home or cloud) implement HTTPS (HTTP over
TLS 1.2) to exchange X.509 and DTCP VidiPath certificates using
Supplemental Data
AUTHENTICATION:
•
•
CERTIFICATE EXCHANGE
VidiPath Clients shall use DTCP VidiPath Certificate:
– Same certificate is used for DTCP Link Protection and VidiPath Authentication.
– This certificate has the VidiPath bit set, which indicates that the Client is VidiPath certified.
VidiPath Servers shall use one of the following:
– Option 1: In-home Authentication Server with DTCP VidiPath Certificate (DLNA Guidelines Part 5
- Device Profiles, Annex A.3):
• Same certificate is used for DTCP Link Protection and VidiPath Authentication.
• Also, a self-signed (non-trusted) X.509 Certificate is used to setup the TLS connection with
a VidiPath client for exchange of DTCP VidiPath Certificate.
– Option 2: Cloud Authentication Server with VidiPath X.509 Certificate (DLNA Guideline Part 5 –
Device Profiles Annex A.4):
• Authentication Server uses trusted VidiPath X.509 cert provided by DTLA, which is used for
both encrypted tunnel establishment between client and server and for server
authentication (since it is trusted).

REQUIREMENTS
• A VidiPath device submitted for DLNA VidiPath certification shall include
Production DTCP VidiPath Certificate/Key with the “VidiPath Certified” bit set:
– The same Certificate/Key is used for DLNA Link Protection capability & VidiPath
Authentication
• DLNA Member company requests VidiPath Production Certificate/Key from
DTLA prior to Certification testing:
– Required in order to submit device for DLNA VidiPath certification testing at an
Independent Certification Vendor (ICV)
– DTLA Adopter’s Agreement includes protections against using VidiPath production
keys in non-VidiPath Certified devices in the marketplace.

Test Tools
CONFORMANCE TEST TOOL
• The CTT is an easy-to-use tool that tests each DLNA Guideline supported
by the product in development.
• With the help of this tool, the test operator can check if the device
complies with the DLNA Guidelines based on the feature set supported by
the product.
• Implements media alignment and scaled files to realistically simulate
actual devices.
42
MEDIA CAPABILITY VERIFICATION TOOL
•
The MCVT is used to verify if the device correctly implements the operations performed
during media playback.
– For example, if the device can perform operations such as play, stop, pause, seek
and scan, this tool will verify if the device correctly performs the operations using
DLNA methods such as connection stalling, byte-based seek, time-based seek, and
play speed as supported.
•
The MCVT allows device vendors the ability to verify that each media format profile will
perform all operations successfully for all possible methods that the device supports.
•
Implements media alignment and scaled files to realistically simulate actual devices.
43
LINK PROTECTION TEST TOOL
•
The LPTT tests the Link Protection Guidelines (DLNA DTCP-IP Guidelines) for
compliance.
•
The LPTT is based on CTT, but the CTT covers Architecture and Protocols and
the LPTT covers the Link Protection Guidelines.
•
Note: LPTT is provided only to Members who have a current DTLA license and
hold Adopter Status.
•
LPTT also has tests similar to MCVT for testing the operations and methods
implementation of a device during media playback, for DTCP-IP media format
profiles.
