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...
This paper demonstrates that growth codes, based on Raptor channel coding, allow incremental protection of H.264 video codec data-partitioned network adaption layer units. When combined with increased protection of video reference frames, in an ADSL erasure channel up to 10 dB in video quality (PSNR) can be gained through this scheme compared to equal error protection with rateless codes. Equivalent...
