Multimedia services including IPTV require huge multimedia data transmission on the Internet. In order to improve a throughput of data transmission, network coding has been proposed to use network bandwidth (=throughput) efficiently with error free channel assumption. However, when the channel is not error free, network coding may not increase the throughput. In this case, effective erasure recovery codes such as Raptor codes have to be used with the network coding. We present the advantage of Raptor codes combined with network coding for high throughput multimedia data transmission services like IPTV. For the applications allowing retransmission, hybrid-ARQ combined with network coding is also considered.
