Abstract

This document extends the Forward Error Correction (FEC) header defined in [RFC2733] and uses this new FEC header for the FEC that is generated by the 1-D interleaved parity code from a source media encapsulated in RTP [RFC3550]. The resulting new RTP payload format is registered by this document.

Abstract

   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.
