| 摘 要： | 提出一种基于数值比特高低位的视频码流划分方式。根据视频码流中信息位置和重要性的不同,对视频序列进行归类,对划分所得的各类信息进行不等差错保护仿真实验,经仿真表明,基于数值比特高低位的视频码流划分方式,相比层次划分及传统图像帧划分方式,经不等差错保护后有更好的视频恢复效果

| Abstract: | A bit based video stream division scheme is proposed.The video series is cataloged on the basis of importance and location of the information in the video stream.The cataloged information is transmitted by unequal error protection.The simulation results shows that the proposed scheme can obtain better performance than the traditional video division scheme |
