Abstract :
This paper demonstrates robust video streaming for IPTV over WiMAX. In the proposed method, an H.264/AVC video bit-stream is data partitioned according to data priority. Raptor channel coding is adaptively applied to the partitioned data. In the event of outright packet drops, redundant partition bearing packets serve to protect priority data. Further, to guarantee a minimum acceptable level of video quality, additional intra-refresh macro-blocks reduce the effect of temporal error propagation.
