compressed video bitstream can be partitioned according to the coding priority of the\ndata, allowing prioritized wireless communication or selective dropping in a congested channel.\nKnown as data partitioning in the H.264/Advanced Video Coding (AVC) codec, this paper introduces\na further sub-partition of one of the H.264/AVC codec�s three data-partitions. Results show a 5 dB\nimprovement in Peak Signal-to-Noise Ratio (PSNR) through this innovation. In particular, the data\npartition containing intra-coded residuals is sub-divided into data from: those macroblocks (MBs)\nnaturally intra-coded, and those MBs forcibly inserted for non-periodic intra-refresh. Interactive\nuser-to-user video streaming can benefit, as then HTTP adaptive streaming is inappropriate and the\nHigh Efficiency Video Coding (HEVC) codec is too energy demanding.
