Hi

This is the summary of open issues to be discussed for the H.264 RTP 
payload format:

o The security section needs review.

o An optional MIME/SDP parameter, max-don-diff, was added as an option 
to control the receiver buffering in the interleaved packetization mode. 
  max-don-diff is specified similarly to the maximum displacement 
parameter in the draft-ietf-avt-mpeg4-simple Internet Draft, but instead 
of using a maximum difference in terms of RTP timestamps a maximum 
difference in terms of decoding order numbers is used.  Does 
max-don-diff bring benefits that justify the complicated receiver 
description?

o ITU-T H.241 provides a way for decoders to signal capability for 
greater processing speed or memory amount than required in the profile 
and level that is used.  H.241 specifies CustomMaxMBPS, CustomMaxFS, 
CustomMaxDPB, and CustomMaxBRandCPB.  Should similar parameters be 
specified as optional MIME/SDP parameters to enhance the capability 
exchange procedure of SIP-based video conferencing?

Please send any comment to the AVT list.

Best Regards
