This draft is a work item of the Audio/Video Transport Working Group of the IETF.

	Title		: RTP Payload Format for Generic Forward Error Correction
	Author(s)	: A. Li
	Filename	: draft-ietf-avt-ulp-19.txt
	Pages		: 42
	Date		: 2006-10-25

This document specifies a payload format for generic Forward
   Error Correction (FEC) for media data encapsulated in RTP. It is
   based on the exclusive-or (parity) operation. The payload format
   described in this draft allows end systems to apply protection
   using various protection lengths and levels, in addition to
   using various protection group sizes to adapt to different media
   and channel characteristic. It enables complete recovery of the
   protected packets or partial recovery of the critical parts of
   the payload depending on the packet loss situation. This scheme
   is completely compatible with non-FEC capable hosts, so the
   receivers in a multicast group that do not implement FEC can
   still work by simply ignoring the protection data. This
   specification obsoletes RFC 2733 and RFC 3009. The FEC specified
   in this document is not backward compatible with RFC 2733 and
   RFC 3009.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
