The FEC Framework [RFC6363] defines a general framework for the use of Forward Error Correction in association with arbitrary packet flows, including flows over UDP and RTP [RFC3550]. Forward Error Correction operates by generating redundant data packets ("repair data") that can be sent independently from the original flow. At a receiver, the original flow can be reconstructed provided a sufficient set of redundant data packets and possibly original data packets are received.

       RTP Payload Format for Raptor Forward Error Correction (FEC)


   This document specifies an RTP payload format for the Forward Error    Correction (FEC) repair data produced by the Raptor FEC Schemes.    Raptor FEC Schemes are specified for use with the IETF FEC Framework    that supports the transport of repair data over both UDP and RTP.    This document specifies the payload format that is required for the    use of RTP to carry Raptor repair flows.
