• Graphics Activity: SVG (video element/API)
• Semantic Web Activity: SWD, SWEO
• Architecture Activity: EXI (container formats)

Video in the Web Activity

http://www.w3.org/2008/WebVideo

• Timed Text Working Group (captioning, video description)
• Media Fragments Working Group (video, audio, and images)
• Media Annotation Working Group: Develop a simple lingua franca ontology and map it to existing formats
• Best Practices and Guidelines for Media Content on the Web (proposal)

Timed Text: Online Captioning

Chairs: Sean Hayes (Microsoft), David Kirby (BBC)

For more information, visit the Working Group page

Media Fragments: Spatial and Temporal

Will provide URI-based mechanisms for uniquely identifying temporal and spatial fragments for media objects on the Web, such as video, audio, and images.

Media Fragments Working Group

Chairs: Erik Mannens (IBBT), Raphaël Troncy (CWI)

Address a region of a media object and the impact at the application level (allow full or partial media retrieval using the HTTP protocol).

Metadata

• Many standards: MPEG 7, SMIL, iTunes XML, Yahoo! MediaRSS, CableLabs VOD Metadata Content, Video sitemaps, etc.
• Different sources: Content Creator, Publisher, Professional Content, Users.
• Survivability: allowing the metadata to survive along the delivery chain (transcoding, republication, syndication, etc.).
• Ability to add metadata without touching the data

Goals:

• Search
• Discover

Related: Metadata Working Group (Canon, Sony, Apple, Microsoft, Adobe)

Media Annotations Working Group: Core Ontology

Chair: Soohong Daniel Park (Samsung), Joakim Söreberg (Ericsson)

simple lingua-franca ontology

Media Annotations Working Group: Metadata API

Client side read-only media annotations API

var vid = document.getElementById("vid");
vid.getTitle();
vid.getAuthor();
vid.getRights();
vid.getLicense();
vid.getCreationDate();

Guidelines for Media Content on the Web (proposal)

• Scope is deployment, use, and manipulation of media content.
• Targeted towards user agents, authoring tools, protocols, and formats.

Potential items on the list:

• Transport protocol guidelines, e.g. bandwidth, use of the HTTP protocol.
• content-adaptation guidelines, e.g. video resolution
• Dealing with media annotations
• User experience guidelines, e.g. localization, captioning, video description, user interface
• Video API guidelines
• Linking from Video content

So, What's in the Web for IPTV and Mobile?

Web technologies are getting deployed on mobiles and televisions.

• Integration Computer/HD Television (e.g. agenda)
• Rich Web Applications: HTML/SVG, CSS, JS
• Widgets
• Bookmarking
• Leveraging the Web and its social networks (imdb, wikipedia, etc.)

Video on the Web is not just what you see

— it's what you can search, discover, create, distribute and manage.
