The IESG has approved the following document: - 'RTP Payload Format for 1-D Interleaved Parity FEC ' <draft-ietf-fecframe-interleaved-fec-scheme-09.txt> as a Proposed Standard This document is the product of the FEC Framework Working Group. The IESG contact persons are Magnus Westerlund and Lars Eggert. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-fecframe-interleaved-fec-scheme-09.txt Technical Summary This document defines a new RTP payload format for the Forward Error Correction 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 new payload format defined in this document is used (with some exceptions) as part of the DVB Application-layer FEC specification. Working Group Summary There were no seriously contentious issues during the WG process. The only controversy stemmed from some individuals who did the work in SMPTE and didn't want the IETF redefining their work. But the problem is that RFC 2733 did not protect some fields in the header and SMPTE was based on RFC 2733. SMTPE spec also made mistakes with SSRC, CSRC and timestamps which are corrected in this document. Additionally, RTP validity checks fail in RPF 2733/SMTPE specs. Document Quality Current implementations follow SMTPE and not yet this specification.
