Comparison of FEC strategies in IPTV

In recent years the forward error correction (FEC) schemes at a binary erasure channel have been researched for many applications including DVB-H and IPTV systems. In most cases the packet-level (FEC) strategies are implemented by either Reed-Solomon (RS) codes at a link layer or Raptor codes at an application layer. Recently an enhanced decoding method for RS codes was presented in. In this paper we consider the performance comparison of the enhanced-decoding RS code at a link layer and Raptor code at an application layer in a burst transmission environment to give a guidance of FEC schemes for IPTV application.
