Internet Television Interoperability RequirementsNew Interoperability requirements from the video transformation of the Internet.

19-Oct-2011 Microsoft Corp 9

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

23001-7 Common encryption in ISO base media file format filesFinal Draft Amendment - ~ July 2011

For broadband television, this standard needs to be compatible with an adaptive streaming standard.

Digital Entertainment

Content Ecosystem

A standard encryption algorithm is the best way to achieve DRM-interoperability.

This leaves the business decision of the DRM technology to use outside the standard.

Encoding

2011-07-19 Microsoft Corporation 15

The UltraViolet CFF Container based on the fragmented form of the 14496-12 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 muxed – which is an important feature for Internet television.‘moo

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

AuthorizationThe IETF OAuth 2.0 specification is becoming the standard token-based 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.

The Future of Internet Television

19-Oct-2011 Microsoft Corp 20

1890s Victorian Trading Card

The Victorian Telephotoscope The futurists predicting

the ‘Telephotoscope’ expected it would be used it to do familiar things in a new way.

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.

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 Internet-delivered video will transform television

International receiver standards will shape this transformation
