[AVT] RTP payload format for H.264

[Magnus Westerlund <magnus.westerlund at ericsson.com>]

Hi,

As you might have seen a new version of the RTP payload format for H.264 
is now available. It can be fetched here:
http://www.ietf.org/internet-drafts/draft-ietf-avt-rtp-h264-05.txt

We have tried to address all known issues, including updating the 
offer/answer section which is the only major change. Please review and 
send any comments ASAP.

We authors are also requesting a WG last call. We authors feel the 
version is good enough, and there are also a rather tight timeschedule 
if we are going to meet 3GPP Release 6 deadline.

The list of changes are:

 Annex A: Changes relative to draft-ietf-avt-rtp-h264-04.txt

    [This section will be removed in a future version of this draft.]

    This memo contains the following technical changes relative to the
    previous I-D:

    o Updated all the boiler plate text to reflect RFC 3667 and RFC
      3668.

    o Rewrote the abstract.

    o Simplified the chapter on RTP header usage to remove fields that
      are not directly used by the RTP payload format.

    o Clarified the usage of the RTP sequence number to determine the
      decoding order for single NALU and non-interleaved mode.

    o Clarified the usage of FU-A also in interleaved mode for any
      fragment after the first, which uses FU-B.

    o Added a new MIME parameter "max-rcmd-nalu-size" that is a hint to
      the largest NALU sizes in bytes that work efficiently for the
      receiver.  Intended usage is gateways.

    o Split MIME parameter "deint-buf-size" into two different
      parameters, a capability part "deint-buf-cap", and stream property
      part "deint-buf-req".

    o Updated the offer-answer consideration section to provide better
      guidelines to ensure interoperability and how offer-answer will
      work with different parameters.

    o Added an IANA consideration section, requesting registration of
      the MIME type.

    o The text for section 11.5 has been updated.

    o Updated the text for the F bit of the NALU header by removing
      normative implementation rules.  Now only informative parts
      remain.

    o Added table in Section 5.3 re recommended NRI values for different
      NAL unit types

    o removed MS-Office hyperlinks (underscores) in the on-line
      references

    o Added a section (8.4) with considerations regarding the handling
      of parameter sets.



Cheers
