Lacan, et al. Standards Track [Page 1]RFC 5510 Reed-Solomon Forward Error Correction April 2009Abstract
This document describes a Fully-Specified Forward Error Correction
(FEC) Scheme for the Reed-Solomon FEC codes over GF(2^^m), where m is
in {2..16}, and its application to the reliable delivery of data
objects on the packet erasure channel (i.e., a communication path
where packets are either received without any corruption or discarded
during transmission). This document also describes a Fully-Specified
FEC Scheme for the special case of Reed-Solomon codes over GF(2^^8)
when there is no encoding symbol group. Finally, in the context of
the Under-Specified Small Block Systematic FEC Scheme (FEC Encoding
ID 129), this document assigns an FEC Instance ID to the special case
of Reed-Solomon codes over GF(2^^8).
Reed-Solomon codes belong to the class of Maximum Distance Separable
(MDS) codes, i.e., they enable a receiver to recover the k source
symbols from any set of k received symbols. The schemes described
here are compatible with the implementation from Luigi Rizzo.
