| 摘 要： | 根据H．264标准的数据分类功能，提出一种数据的不平等保护策略。该策略利用信道的反馈信息预测信道丢包率，调整H．264视频码流各分类区的信道码率。实验结果表明，该策略能有效的提高视频码流的误码鲁棒性。

| Abstract: | According to the data portioning of the H.264 video compression standard, an Unequal Error Protection （UEP） scheme is proposed in this paper. This scheme predicated the packet loss ratio by the feedback information of the wireless channel and adjusts the channel rate for each partition of the H.264 video stream adaptively, Experiments show that this scheme can improve the error robustness of the video stream effectively. |
