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. [STANDARDS TRACK]
