TPAC 2023 is planned to be held in Seville from 11 to 15 September 2023. These will be hybrid meetings with in-person and remote attendance, as last year.

Groups are being asked to give an indication of their meeting plans, by 8 May.

My suggestion would be we do the same as last year: 4 hours of meetings, in two 2-hour sessions.

If we were to plan a hybrid Media WG meeting, would you want (or be able to) join in person in Seville?

Please indicate your preference on whether you'd plan to travel. This is to get a sense of the number of people who would be there in person, so we have an appropriate sized room. I realize this is very early, so not looking for you to commit right now.

  • 👍 if you would plan to join in person
  • 👎 if you can only join a virtual meeting

We can also organize joint meetings with other groups as needed, such as Audio WG, Web RTC WG, Timed Text WG, Media & Entertainment IG, Please leave a comment with your suggestions.

I would propose that we try to schedule media-related topics at the beginning of the week to allow travel time for any folk heading to Amsterdam for IBC (begins on the Friday of TPAC week).

I agree. I also would like to coordinate the requests for meeting times across the various media related groups. (I have emailed group chairs about that.)

Last call for topics is this Friday the 4th of August! Agenda is pretty settled based on above.

It would be great to have a list of issues for each spec. But getting status update on each spec would be amazing.
