Title : An RTP Payload Format for Erasure-Resilient
Transmission of Progressive Multimedia Streams
Author(s) : G. Liebl, et al.
Filename : draft-ietf-avt-uxp-07.txt
Pages : 29
Date : 2004-10-26
This document specifies an efficient way to ensure erasure-
resilient transmission of progressively encoded multimedia
sources via RTP using Reed-Solomon (RS) codes together with
interleaving. The level of erasure protection can be explicitly
adapted to the importance of the respective parts in the source
stream, thus allowing a graceful degradation of application
quality with increasing packet loss rate on the network. Hence,
this type of unequal erasure protection (UXP) schemes is intended
to cope with the rapidly varying channel conditions on wireless
access links to the Internet backbone. Furthermore, protection of
non-progressive multimedia streams is ensured, since equal
erasure protection (EXP) represents a subset of generic UXP. By
applying interleaving and RS codes a payload format is defined,
which can be easily integrated into the existing framework for
RTP.

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
