In 2007, the IP Infrastructure (IPI) Technical Module (TM) of the Digital Video Broadcasting (DVB) consortium published a technical specification [ETSI-TS-102-034v1.3.1] through the European Telecommunications Standards Institute (ETSI). [ETSI-TS-102-034v1.3.1] covers several areas related to the transmission of MPEG2 transport stream-based services over IP networks.

 Guidelines for Implementing Digital Video Broadcasting - IPTV (DVB-IPTV)    Application-Layer Hybrid Forward Error Correction (FEC) Protection


   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.
