| Popis: | 93 We analysize the problem of optimal data partitioning of H.264 coded video in operational rate-distortion context. Traditionally, we partitioned the syntax element to fixed partitions. But fixed partitioning does not fit well with the different network. We try to do adaptive data partition by Lagrange multiplier to partition H.264 encoded bitstream into two partition. Because of intra prediction of H.264, the MBs in a frame has relationship with other MBs in the same frame, especially for the first column and the first row. So we put these MB data to partition 0 which is transmitted on a perfect channel with no losses. On average, the experiment results by the Lagrange multiplier with putting special MBs in partition 0 and Lagrange multiplier, the former is superior at the same bitrate. |
