RTP Payload Format for 1-D Interleaved Parity Forward Error Correction (FEC), October 2010
Discuss this RFC: Send questions or comments to email@example.com
This document defines a new RTP payload format for the Forward Error Correction (FEC) that is generated by the 1-D interleaved parity code from a source media encapsulated in RTP. The 1-D interleaved parity code is a systematic code, where a number of repair symbols are generated from a set of source symbols and sent in a repair flow separate from the source flow that carries the source symbols. The 1-D interleaved parity code offers a good protection against bursty packet losses at a cost of reasonable complexity. The new payload format defined in this document should only be used (with some exceptions) as a part of the Digital Video Broadcasting-IPTV (DVB- IPTV) Application-layer FEC specification.
