CONNECTING THE FUTURE OF SUBSCRIPTION TV CONTENT THROUGH

Benefits

Allows consumers to access the full range of

service provider content on multiple devices in

the home.

Eliminates the hassle of additional boxes, cords, remotes and

other service provider specific devices.

Enables a consistent service provider user

interface across devices.

The VidiPath logo helps consumers purchase

devices that access service provider content

VidiPath clients will work with the billions of DLNA Certified devices on the

market today.

VidiPath devices have low power capabilities

built in, reducing consumer’s energy

consumption.

Consumer Benefits

Preserves content provider rights through

protected streaming using DTCP-IP and

Authentication.

Reduces service provider capital expenditure by enabling the move to

headless gateways and reducing the number of

set top boxes in the home.

Enables a consistent service provider user

interface across devices.

Allows SPs to build a single UI which eliminates the need to manage multiple unique

applications for devices (i.e., TV, tablet, phone, PC, etc.).

Remote diagnostics allows service

providers to optimize user experience.

A Common product logo gives service providers a

way to communicate which devices can access

full subscription TV content.

Service Provider Benefits

Gives CE devices access to the full range of subscriber HD

programs, movies, DVR content, channel guides, and

other premium features.

Utilize DLNA’s formal test suite and certification

program to ensure interoperability amongst

devices.

Leverages existing DLNA implementations with

minimal enhancements.

Having a common profile minimizes the need to

support individual service provider applications.

VidiPath logo provides CE manufacturers a way to

differentiate their products.

HTML5 RUI: RENDERS SERVICE PROVIDER USER INTERFACE ON DEVICES

• Enables service providers to render their UIs (e.g. program guide) onto VidiPath Clients.

• HTML5 RUI profile for DLNA Clients conformant to commercial browsers implementations.

• HTML5 provides a consistent user experience.• HTML5 allows for a single unified user interface adapted to screen resolution. • Discovery is based on UPnP Remote User Interface specification.• Pixel-accurate relies on CANVAS, a HTML5 tag for dynamic, scriptable rendering

of 2D shapes and bitmap images.• Supports the same mandatory trick modes and media format profiles as DLNA

Device Classes DMS/DMP/DMR.

DTCP-IP: PROTECTING STREAMING CONTENT

Service Providers

• 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.

NETWORKED DEVICES POWER SAVE: CONSERVING ENERGY

• For tighter power regulations and voluntary initiatives.

• Provides mechanism for DLNA devices to convey energy management capabilities and mode for each of its network interfaces.

• Technology-based on UPnP Energy Management service.

• Clients are enabled to provide wakeup or reservation mechanism to manage devices (Optional):

• To wake up end point devices on demand. • To request an end point device to be on for a given period of time.

• Allows devices to proxy knowledge of energy management capabilities and mode for other devices.

Adapts to network conditions inside and outside the home

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 CERTIFICATION

Are you really a VidiPath client?

Are you really a VidiPath server?

Service Providers

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

• 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).

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.
