2 I want you to meet these guys they have the hottest new stupid thing on the Internet.

3 Agenda A Brief Historical Perspective The Video Transformation of the Internet Internet Television Interoperability Requirements Emerging Internet Television Receiver Standards The future of Internet television 19-Oct-2011 Microsoft Corp 3

4 A Brief Historical Perspective Standardization, interoperability and the growth of horizontal markets. 19-Oct-2011 Microsoft Corp 4

5 Average Annual U.S. Television Set Sales ( ) FCC adopts NTSC Standards, May Oct-2011 Microsoft Corp 5

6 U.S. DVD RENTAL & SELL THROUGH (Billions) DVD Format in Japan DVD Format in US DVD Format in Europe DEG: The Digital Entertainment Group 19-Oct-2011 Microsoft Corp 6

7 The Video Transformation of the Internet How broadband-broadcast convergence is transforming the Internet. 19-Oct-2011 Microsoft Corp 7

8 IP traffic video will represent 90 percent of all Internet traffic by Cisco Oct-2011 Microsoft Corp 8

9 Internet Television Interoperability Requirements New Interoperability requirements from the video transformation of the Internet. 19-Oct-2011 Microsoft Corp 9

10 Baseline Internet TV Receiver Requirements Ubiquity of the Internet argues for International standards Encoding DRM-interoperable - minimum number of encoding formats Common encoding for download to own, on-demand, live and multicast Easy transcoding to other formats Track delivery Adaptive delivery with effective edge caching Independently addressable tracks 19-Oct-2011 Microsoft Corp 10

11 Central interoperability issues Adaptive bitrate streaming Hybrid television Application portability Digital Rights Management Internet Televisio n Authenticati on and authorization 19-Oct-2011 Microsoft Corp 11

12 Internet Television Receiver Standards Meeting the Internet TV interoperability issues has led to the emergence of Internet Television Receiver Standards. 19-Oct-2011 Microsoft Corp 12

13 Internet television Receiver Standards Application Authorization Transport W3C HTML Enhancements for Television * Video Authorization Profile of IETF OAuth 2.0 * IETF Simple Web Discovery (SWD) ISO MPEG Dynamic Adaptive Streaming over HTTP (DASH), Live Profile Encoding Encryption ISO MPEG DRM-Interoperable fragmented MP4 (e.g. UltraViolet Common File Format) for live, ondemand, DTO ISO MPEG Common Encryption (CENC) 19-Oct-2011 Microsoft Corp 13

14 A standard encryption algorithm is the best way to achieve DRMinteroperability. This leaves the business decision of the DRM technology to use outside the standard. Contribute Publish Under Community Promise (royalty free) Protected Interoperable File Format Sept 2009 Encryption Digital Entertainment Content Ecosystem Liaison MPEG - ISO/IEC JTC1/SC29 WG11 Publish Common File Format Q For broadband television, this standard needs to be compatible with an adaptive streaming standard Microsoft Corporation Common encryption in ISO base media file format files Draft Amendment - January Common encryption in ISO base media file format files Final Draft Amendment - ~ July

15 Encoding 1-3 Seconds moo v moo f traf mdat Audio moo f traf The UltraViolet CFF Container based on the fragmented form of the ISO Base Media File Format. Each fragment individually decodable and decryptable, 1-3 seconds of video time - optimal for adaptive bitrate streaming. Each fragment contains only one track type samples are not mdat Video muxed which is an important feature moo for Internet television. f traf mdat Audio mfra Microsoft Corporation 15

16 Trans port Media Preparatio n Media Origin Servers HTTP Servers HTTP over Fixed and Mobile Networks Common encryption means the same short fragment of video can be decrypted and decoded by devices using different DRMs. CFF single track per fragment means tracks can be combined at the client device Improved encoding, network cache (origin vs. edge server) and CDN efficiencies Short segments of video stored as CFF movie fragments, requested with HTTP and spliced together by client. Uses existing Internet CDNs traverses NAT/Firewalls fixed-mobile convergence. 19-Oct-2011 Microsoft Corp 16

17 Authorization The IETF OAuth 2.0 specification is becoming the standard tokenbased authorized access to protected web resources RESTful - only client software requirement is HTTP. Token discovery for native and web applications. Secure encryption and digital signature. Profile to incorporate the MVPD-broadcaster and MVPD-Subscribers relationships TV Everywhere. Support for multiple authorization providers long tail, niche verticals. IETF Simple Web Discovery (SWD) for Authorization provider discovery. 19-Oct-2011 Microsoft Corp 17

18 Application W3C Web and Television Interest Group Home Networking Task Force Media Pipeline Task Force Large attendance from broadcaster, television industry Requirements setting activities Adaptive Streaming, Digital Rights Management, Authorization, Device Discovery Specification work will happen in W3C working groups 19-Oct-2011 Microsoft Corp 18

19 Summary W3C Web and TV enhancements to HTML (in discussion) An IETF OAuth 2.0 Profile for Internet Television (drafting begun) ISO MPEG Dynamic Adaptive Streaming over HTTP (under ballot, 2011) IETF Simple Web Discovery (under ballot, 2011) UltraViolet Common File Format (published, 2011) ISO MPEG DRM-Interoperable Common Encryption (under ballot, 2011) 19-Oct-2011 Microsoft Corp 19

20 The Future of Internet Television 19-Oct-2011 Microsoft Corp 20

21 The Victorian Telephotoscope The futurists predicting the Telephotoscope expected it would be used it to do familiar things in a new way. 1890s Victorian Trading Card They could not anticipate television channels, networks, affiliates and commercial breaks. We face an equal challenge predicting the future of television in the era of internet television receivers.

22 Impact of Internet Television Receiver Standards Internet TV will become more than an alternative pipe for delivering broadcast television content Internet and broadcast TV will become relatively indistinguishable to consumers Video is transforming the Internet and Internetdelivered video will transform television International receiver standards will shape this transformation 07/13/2011 Microsoft Corporation 22
