Title : RTP Payload Format for Generic Forward Error Correction
Author(s) : A. Li
Filename : draft-ietf-avt-ulp-16.txt
Pages : 45
Date : 2006-3-2
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, and it is a
generalized algorithm that includes Uneven Level Protection
(ULP). The payload format described in this draft allows end
systems to apply protection using arbitrary protection lengths
and levels, in addition to using arbitrary protection group
sizes. 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 backward
compatible with non-FEC capable hosts. The receivers that do not
implement FEC can still work by simply ignoring the protection
data. This specification obsoletes 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.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
