Video in the Web Activity Statement

The goal of this activity is to make video a first class citizen of the Web. Video on the Web (and this includes audio, as the two are typically used together) has seen explosive growth, improving the richness of the user experience but leading to challenges in content discovery, searching, indexing and accessibility. Enabling users (from individuals to large organizations) to put video in the Web requires that we build a solid architectural foundation that enables people to create, navigate, search, link and distribute video, effectively making video part of the Web instead of an extension that doesn't take full advantage of the Web architecture.

Highlights Since the Previous Advisory Committee Meeting

The mission of the Timed Text Working Group is to provide a language that represents timed text media. Timed text is textual information that is intrinsically or extrinsically associated with timing information used for the purpose of transcoding or exchanging timed text information among legacy distribution content formats presently in use for subtitling and captioning functions.

The group has published the following documents:

Timed Text Markup Language (TTML) 1.0 a W3C Recommendation,18 November 2010. No feature has been removed from the 2006 version of the specification but dynamic flow was significantly rewritten.
Timed Text Markup Language 1 (TTML1) (Second Edition), a W3C Recommendation, 24 September 2013.
The group is now working on the new TTML2 specification.
