Abstract



This document specifies a payload format for generic forward error

correction of media encapsulated in RTP. It is engineered for FEC

algorithms based on the exclusive-or (parity) operation. The payload

format allows end systems to transmit using arbitrary block lengths

and parity schemes. It also allows for the recovery of both the

payload and critical RTP header fields. Since FEC is sent as a

separate stream, it is backwards compatible with non-FEC capable

hosts, so that receivers which do not wish to implement FEC can just

ignore the extensions.
