Re: [AVT] SVC ad-hoc meeting , February 19 remind +1-678-7955235



I’ve had a quick scan of the e-mails on the list since I sent some comments on the draft on 8th February. Of those comments, the following five perhaps need some discussion.

 

1. Introduction and Scope – should some of the text in the Scope be moved to the introduction?

 

6. Timestamps across sessions. These should have different offsets, but should they be sampled from the same clock?

 

11. Various bits in PACSI, such as the A bit. Can these bits be defined in a meaningful way without specifying constraints on the contents of other aggregation packets than the one in which the actual PACSI is present?

 

15. Repeated SEI messages in PASCI and the other NAL units in an aggregation packet. These should be discouraged, but there appears to be no restriction in H.264/AVC/SVC on repeated SEI messages.

 

25. In which stream should repeated SEI messages be present (and other non-VCL NAL units). This is also open issue 9 in the draft.

 

 

Also, Alex raised the issue of whether the S and E bits and TL0PICIDX should use the same flag rather than the X and Y flags; and Jonathan and Colin mentioned the possibility of defining a generic RTP extension for cross-session decoding.

 

 

 

Best regards

 

Mike
