This group is chartered to develop formats used for the representation of streamable text synchronized with other timed media, like audio and video. Such formats MUST be useable for online media captioning, described video (aka video/audio description) and should address the media accessibility user requirements.

The new work is expected to be broadly available and should be provided on a timely fashion. This charter features a tightly constrained scope designed to ensure that the Working Group will meet its schedule and objectives.
The Working Group is expected to demonstrate at least two interoperable implementations of all available features in the specification.
The Working Group will update the test suite intended to promote implementations of the above specification(s) and to assess interoperability between these implementations. The Group will also produce an implementation report for each deliverable.
The Working Group may also propose a new charter for follow on work on the specification.
Note: The group will document significant changes from this initial schedule on the group home page. | ||||||

As part of the Video in the Web Activity, the Timed Text Working Group will be represented in the Hypertext Coordination Group.
To be successful, the Timed Text Working Group is expected to have 5 or more active participants for its duration. Effective participation to Timed Text Working Group is expected to consume one half-day per week for each participant; one day per week for editors. The Timed Text Working Group will allocate also the necessary resources for building Test Suites for each specification.
Participants are reminded of the Good Standing requirements of the W3C Process.
This group primarily conducts its work on the public mailing list public-tt@w3.org (archive).
A Member-only mailing list, member-tt@w3.org (archive) is available for administrative purposes such as liaison with Member-only Working Groups.
Information about the group (deliverables, participants, face-to-face meetings, teleconferences, etc.) is available from the Timed Text Working Group home page.
As explained in the Process Document (section 3.3), this group will seek to make decisions when there is consensus. When the Chair puts a question and observes dissent, after due consideration of different opinions, the Chair should record a decision (possibly after a formal vote) and any objections, and move on. This charter is written in accordance with Section 3.4, Votes of the W3C Process Document and includes no voting procedures beyond what the Process Document requires.
This Working Group operates under the W3C Patent Policy (5 February 2004 Version). To promote the widest adoption of Web standards, W3C seeks to issue Recommendations that can be implemented, according to this policy, on a Royalty-Free basis.
For more information about disclosure obligations for this group, please see the W3C Patent Policy Implementation.
This charter for the Timed Text Working Group has been created according to section 6.2 of the Process Document. In the event of a conflict between this document or the provisions of any charter and the W3C Process, the W3C Process shall take precedence.
Please also see the previous charter for this group.
The previous charter is also available.
