Dear Philippe:

The SMPTE believes it would be beneficial to the industry if W3C were to re-charter the WG for the following activities:

1. Maintenance of the Recommendation and related schemas;

2. Development of additional common constraint profiles as required by industry;

3. Consider adding the extensions designed by SMPTE and others; 

4. Consider improving the extensibility of elements; and 

5. Consider specifying synchronized delivery of live encoded captions with video, where short packets of video and text are encoded and delivered, and those segments of TTML must add to or replace elements in a document currently being presented.

Regards,
	Michael Dolan, 24TB Committee Co-Chair
	for Hans Hoffman, SMPTE Engineering VP

Subject: TTML after March

The charter of the TTML Working Group will expire at the end of March
2012 [1] (it was extended for one year in 2011). I'm curious about the thoughts from individuals here about what to do, if anything, beyond the end of March.

For example, SMPTE did some extensions to SMPTE-TT back in 2010. Should we look at those and fold them back in the specification?

Dynamic flow was removed from the specification due to lack of implementation experience. Should it be reconsidered?

Should we switch from XSL FO to CSS?

Should we do a profile of TTML as well and retaining features that are the most deployed?

Or should the group just declare victory and go home?

Thank you,

Philippe

PS: if someone wants to ask the Timed Text Community Group for feedback on this matter as well, feel free to forward this message. Input is welcome!
