Abstract
In recent years the forward error correction (FEC) schemes at the 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 the link layer or Raptor codes at the application layer. Recently an enhanced decoding method for RS codes was presented. The enhanced-decoding scheme is a combination of erasure and error decoding. In this paper we consider the performance comparison of the enhanced-decoding RS code at the link layer and Raptor code at the application layer in the burst mode transmission to give a guidance of FEC scheme for IPTV application. It is noted that the efficient Raptor decoding algorithm makes it possible to broadcast multimedia data more reliable and faster.
