Title : 1-D and 2-D Parity FEC Scheme for FEC Framework
Author(s) : A. Begen, R. Asati
Filename : draft-begen-fecframe-1d2d-parity-scheme-00.txt
Pages : 22
Date : 2008-02-18
This document describes a Fully-Specified Forward Error Correction
(FEC) Scheme for the one-dimensional (1-D) and two-dimensional (2-D)
parity codes and its application to reliable delivery of media
streams in the context of FEC Framework. The 1-D and 2-D parity
codes are systematic codes, where a number of repair symbols are
generated from a set of source symbols and sent in one or more repair
flows in addition to the source symbols that are sent to the
receiver(s) within a source flow. The 1-D and 2-D parity codes offer
a good protection against random and bursty packet losses at a cost
of decent complexity. This document also specifies an RTP payload
format for the FEC that is generated by the 1-D and 2-D parity codes
from a source media encapsulated in RTP. The FEC defined in this
document is not backward compatible with RFC 5109.

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.
