Abstract:
   This document defines new RTP payload formats for the Forward Error
   Correction (FEC) packets that are generated by the non-interleaved
   and interleaved parity codes from source media encapsulated in RTP.
   These parity codes are systematic codes, where a number of FEC repair
   packets are generated from a set of source packets from one or more
   source RTP streams.  These FEC repair packets are sent in a
   redundancy RTP stream separate from the source RTP stream(s) that
   carries the source packets.  RTP source packets that were lost in
   transmission can be reconstructed using the source and repair packets
   that were received.  The non-interleaved and interleaved parity codes
   which are defined in this specification offer a good protection
   against random and bursty packet losses, respectively, at a cost of
   decent complexity.  The RTP payload formats that are defined in this
   document address scalability issues experienced with the earlier
   specifications, and offer several improvements.  Due to these
   changes, the new payload formats are not backward compatible with
   earlier specifications, but endpoints that do not implement this
   specification can still work by simply ignoring the FEC repair
   packets.
