Title : An Adaptive FEC to Protect RoHC and UDP-Lite Vital Video Data
Author(s) : Z. Chen
Filename : draft-chen-afec-01.txt
Pages : 20
Date : 2007-3-22
This document generally describes how to use an Adaptive Forward
Error Correction (AFEC) algorithm to efficiently protect the
compressed header vital data as well as UDP-Lite?s vital data for
data transport in the radio-link layer of an error-prone wireless
connection. Augmented with RoHC and UDP-Lite, for video
transmissions over wireless channels in a heterogeneous wired-
wireless environment, the erroneous packet payloads can be useful
and the applications better able to cope with lost packets (native
UDP case), by adopting some of the erasure and error resilient
modes in the latest video codecs, such as H.264. The context
transfer in the inter/intra handover is also covered.

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
