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 discusses the
   best way of accomplishing simulcast in RTP and how to signal it in
   SDP.  A solution is defined by making an extension to SDP, and using
   RTP/RTCP identification methods to relate RTP streams belonging to
   the same media source.  The SDP extension consists of a new media
   level SDP attribute that expresses capability to send and/or receive
   simulcast RTP streams.  RTP/RTCP identification using either payload
   types or a separately defined method for RTP stream configuration are
   defined.
