Description: This document specifies a payload format for generic Forward Error
Correction (FEC) for media data encapsulated in RTP. It is based on
the exclusive-or (parity) operation. The payload format described in
this document allows end systems to apply protection using various
protection lengths and levels, in addition to using various
protection group sizes to adapt to different media and channel
characteristics. It enables complete recovery of the protected
packets or partial recovery of the critical parts of the payload
depending on the packet loss situation. This scheme is completely
compatible with non-FEC-capable hosts, so the receivers in a
multicast group that do not implement FEC can still work by simply
ignoring the protection data. This specification obsoletes RFC 2733
and RFC 3009. The FEC specified in this document is not backward
compatible with RFC 2733 and RFC 3009.
