Thanks for fixes.   I assume Dave will update before posting.

As for the your second point, I am not sure that I follow.  We must define the new media type parameter formally in TTML2 or our decisions and this communication are meaningless.  Is your point that we did not agree as a group to register the update with IANA?  I agree, but I also did not say that to MPEG (although I personally think we should).


I was expecting the MIME type parameter to be external to TTML2 and defined on the registry page. I'm not against updating the IANA registration if that's useful but we haven't decided to do that. If we do, then clearly the relevant part of the TTML 2 spec would need updating to match. If we don't, then there may be no changes resulting, in TTML2.

Since there may therefore be no change in TTML 2 I don't want to give the wrong impression.

Thanks for the quick turnaround Mike. 3 things:

typo: s/medaType/mediaType
correction: s/procProfile/processorProfiles

Query: do we want the sentence "Its parameters will be extended in TTML2 to include the proposed syntax above." ? Unless we're changing the IANA registration then I do not think we have agreed to do this.

Kind regards,

Nigel

Per my action item from today, please see the attached.

Over to Dave and Nigel for review to see if I captured where we ended up in today’s call; then over to Dave to upload to MPEG (or I can if needed).

Time is very short and should be posted Sunday morning CEDT.
