Title : DVB Application-Layer Hybrid FEC Protection
Author(s) : A. Begen, T. Stockhammer

This document describes the Application-layer Forward Error
Correction (FEC) protocol that was developed by the Digital Video
Broadcasting (DVB) consortium for the protection of media streams
over IP networks. The DVB 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 AL-FEC offers a good
protection against both bursty and random packet losses at a cost of
decent complexity. The 1-D interleaved parity code and Raptor code
have already been specified in separate documents and the current
document normatively references these specifications.
