Data partitioning is a way of separating out data from a compressed bitstream according to its importance in reconstructing a video stream. This paper notices that this procedure also results in relatively smaller packets for more important data if the quantization parameter (QP) is set accordingly. Raptor channel coding is then applied and the quality of the video is improved by distributing a significant proportion of intra-coded macroblocks within predictively coded frames. When this scheme is applied to an IEEE 802.16e (mobile WiMAX) system, according to frame size a number of trade-offs arise in respect to balancing the number of packet drops, corrupted packets through channel conditions, overall video quality, and data latency.
