RE: proposed updated response to MPEG on codecs

In spirit I agree - thanks.  But you removed the tie-back to refinement of the communication of 30-April.  I think it is important to note that we are clarifying that.

Sorry I could not attend today's call. The liaison is good. I just think it should be clear that:

- the first part (stpp.mediaType) is a proposal to MPEG but the final decision is left to MPEG.

- the second part ( application/ttml+xml;procProfile=dialect1…dialectn)
is the responsability of the TTWG.

So, I'd suggest the following changes (or similar):

s/We offer to refine the proposal that the codecs parameter be of the form:/We recommend MPEG to define the codecs parameter for subtitle and timed text tracks of the form:/ and s/Where “/medaType/” is a fully qualified media type string, including parameters/Where “/mediaType/” is a fully qualified media type string, including parameters, as defined by the IANA registry for the data carried in the track/

s/, of the form:/To assist ISOBMFF players in identifying the flavor of TTML documents from the above proposed codecs value, the W3C TTWG will
define: a) a new parameter to the TTML MIME to specify and combine short identifiers for profiles, b) a registry for the association between the short identifier and the associated specification of the TTML profile.

Regards,
Cyril
