Technical Summary

This document describes Fully-Specified Forward Error Correction
(FEC) Schemes for the Raptor and RaptorQ codes and their application
to reliable delivery of media streams in the context of FEC
Framework. The Raptor and RaptorQ 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
Raptor and RaptorQ codes offer close to optimal protection against
arbitrary packet losses at a low computational complexity. Six FEC
Schemes are defined, two for protection of arbitrary packet flows,
two that are optimised for small source blocks and another two for
protection of a single flow that already contains a sequence number.
Repair data may be sent over arbitrary datagram transport (e.g. UDP)
or using RTP.

Working Group Summary

There has been controversy over this document in the past, but by now it
represents WG consensus.

IPR was declared, and announced in 2009
http://www.ietf.org/mail-archive/web/fecframe/current/msg00514.html
updated in 2011 http://www.ietf.org/mail-archive/web/fecframe/current/msg00886.html,
and updated in 2012 http://www.ietf.org/mail-archive/web/fecframe/current/msg00985.html
The WG is aware of the IPR and is fine with the situation.
