| 摘 要： | H.264/AVC标准引入的灵活宏块排列机制可以显著改善解码重建视频的质量。为进一步增强在不可靠信道上传输视频的鲁棒性,提出了在运动向量搜索的率失真优化框架下,结合灵活宏块排列容错机制,对差错隐藏失真进行优化。实验结果表明该方法能有效地提高灵活宏块排列的容错性能。

| Abstract: | Flexible Macroblock Ordering(FMO) feature of the H.264/AVC codec improves the decoded video quality remarkably.In order to further increase the robustness of the transmitted video over unreliable channels,distortion introduced by error concealment is taken into consideration under R-D optimized motion vector selection framework in the presence of FMO mechanism,this allows optimization of concealment distortion at the encoder.Experiment result is given to show the performance of the proposed method. |

| Keywords: | Flexible Macroblock Ordering(FMO) error concealment optimal motion vector selection |
