Annex E of the Digital Video Broadcasting - IPTV (DVB-IPTV) technical
specification defines an optional Application-Layer Forward Error
Correction (AL-FEC) protocol to protect the streaming media
transported using RTP. The DVB-IPTV AL-FEC protocol uses two layers
for FEC protection. The first (base) layer is based on the 1-D
interleaved parity code. The second (enhancement) layer is based on
the Raptor code. By offering a layered approach, the DVB-IPTV AL-FEC
protocol offers good protection against both bursty and random packet
losses at a cost of decent complexity. This document describes how
one can implement the DVB-IPTV AL-FEC protocol by using the 1-D
interleaved parity code and Raptor code that have already been
specified in separate documents. This document is not an Internet
Standards Track specification; it is published for informational purposes.
This document is a product of the FEC Framework Working Group of the IETF.
