Hi,

During the Vancouver meeting we had an ad-hoc meeting to discuss how to progress the SVC payload specifications in draft-ietf-avt-rtp-svc-03.

In the ad0hoc meeting we had Stephan Wenger, Ye Kui Wang, Thomas Schierl, Jonathan Lennox, Thomas Wiegand, Geoff Hunt and the AVT chairs.

Currently the open issues as was summarized in the ad-hoc and based on the email discussion and other feedback include:

1.	Cross layer decoding order dependency - two suggested solutions on the table. Need to agree if use one or both. In the case of both how to resolve interoperability. Initial step is to update text explaining the usage. 
2.	Backward compatibility to H264 enabling H264 (RFC 3984 single NAL unit) to interoperate with H.264SVC using base layer. Need more definition. 
3.	Clarify the PACSI packet since there were changes between the draft revision 
4.	Fix the format of the document and review the SDP parameters. 
5.	Changed semantics between RFC 3984 and svc like sprop-deint-buf-req - probably will need new parameters. 
6.	What to do with bugs in RFC 3984 
7.	Clarify the usage of the new parameters like sprop-scalability-info, relation to SEI and usage in offer/answer 
8.	The text should be clear enough to allow an implementer to use it for creating the payload without having to read the H.264 SVC document. 

It was decided to form a design team that will meet (audio conference) every two weeks in order to expedite the work and address the above open issues.  The objective is to have a version ready for WGLC before the next IETF meeting.

The first meeting of the design team will be on January 8th at 7:00 AM PST, 17:00 Israel/Finland, 16:00 Germany. See the link for your time

Anyone that would like to contribute to this effort is invited to join the design team.

Please send an email to the AVT working group chairs if you intend to contribute and would like to be part of the design team.

Roni Even
