11 The FCC and DLNA produces open industry standards
The FCC output requirements will come into effect on June 1, 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. Reference: Implementation of Section 304 of the Telecommunications Act of 1996; Commercial Availability of Navigation Devices, CS Docket No ; Audiovisual Output Requirement of Section (b)(4)(iii). https://apps.fcc.gov/edocs_public/attachmatch/DA A1.pdf As discussed below, we clarify the elements of an “open industry standard” for purposes of Section (b)(4)(iii). We conclude that the processes that the Digital Living Network Alliance (“DLNA”)23 uses to develop and adopt its home networking specifications satisfy the elements of an “open industry standard.” We thus believe that the home networking solution that DLNA is working on now — a successor to the current “DLNA Premium Video profile”24 — will meet the output requirements in Section (b)(4)(iii) as long as it supports the required features of recordable high-definition video, closed captioning data, service discovery, video transport, and remote control command pass-through. Although other standards may also meet these elements, we do not express a view on those here

20 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.

21 DTCP-IP: Protecting Streaming Content
Service Providers DTCP-IP protects the link over which the content is transferred. Thus enabling secure sharing of content between products in a consumer’s home that supoprt DTCP-IP.

22 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.

32 Authentication: Verifying Certification
Are you really a VidiPath client? Service Providers 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

33 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 Device Profiles, Annex A.3): 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).

34 Authentication: DTCP Method In-Home Authentication Server
Client provides DTCP VidiPath Certificate in TLS Supplemental Data signed with Client’s DTCP Private Key Service Providers HTTPS (HTTP over TLS 1.2) In-home Server provides A self-signed server X.509 Certificate With DTCP VidiPath Certificate in TLS Supplemental Data signed with Server’s DTCP Private Key DLNA Guidelines Part 5 – Device Profiles, Annex A.3, B.3, B.4

35 Authentication: X.509 Method Cloud Authentication Server
Client provides DTCP VidiPath Certificate in TLS Supplemental Data signed with Client’s DTCP Private Key Service Providers HTTPS (HTTP over TLS 1.2) Cloud Server provides Trusted X.509 VidiPath Certificate DLNA Guidelines Part 5 – Device Profiles, Annex A.4, B.1, B.2

Test Tools

42 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. 

43 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. 

44 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.
