Agenda+ Assign Roles

 

Chair: Nigel Megitt

 

Scribe: [to assign during meeting]

 

Regrets: 

 

Activity since last meeting: 

 

Agenda+ Prioritise discussion for this meeting

 

Check-point for order of topics – I'd suggest:

1. MIME codecs parameter if we're quorate on this topic

2. SMPTE liaison,

3. Change proposal 2,

4. Pending Review actions and issues,

5. Raised issues

6. Overdue actions.

 

And stop when time runs out – I'm happy to set and impose time limits on
these topics if members would like to take that approach.

 

Agenda+ MPEG liaison re MIME Codecs parameter

 

This is scheduled for a major discussion for this topic since all main
contributors will hopefully attend.
