Re: [MMUSIC] I-D Action: draft-ietf-mmusic-sdp-simulcast-04.txt

This new version contains the following changes:

   o  Changed to only use RID identification, as was consensus during
      IETF 94.

   o  ABNF improvements.

   o  Clarified offer-answer rules for initially paused streams.

   o  Changed references for RTP topologies and RTP taxonomy documents
      that are now published as RFC.

   o  Added reference to the new RID draft in AVTEXT.

   o  Re-structured section 6 to provide an easy reference by the
      updated IANA section.

   o  Added a sub-section 7.1 with a discussion of bitrate adaptation.

   o  Editorial improvements.

> Abstract:
>    In some application scenarios it may be desirable to send multiple
>    differently encoded versions of the same media source in different
>    RTP streams.  This is called simulcast.  This document describes how
>    to accomplish simulcast in RTP and how to signal it in SDP.  The
>    described solution uses an RTP/RTCP identification method to identify
>    RTP streams belonging to the same media source, and makes an
>    extension to SDP to relate those RTP streams as being different
>    simulcast formats of that media source.  The SDP extension consists
>    of a new media level SDP attribute that expresses capability to send
>    and/or receive simulcast RTP streams.
