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.", "pub_date": "August 2012", "keywords": [ "DVB", "FEC", "AL-FEC", "IPTV", "parity codes", "Raptor codes" ], "obsoletes": [], "obsoleted_by": [], "updates": [], "updated_by": [], "see_also": [], "doi": "10.17487/RFC6683", "errata_url": null }
