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 the 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 the protection of arbitrary packet flows,
two that are optimized for small source blocks, and two for the
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.  [STANDARDS-TRACK]
