摘要

本文提出了一种利用相位置乱来降低视频序列通信中数据丢失影响的方法。相位置乱用于将视频序列的每个像素的数据分散到置乱视频的所有像素上。在我们的实验中，我们研究了不同损失模式的影响。与不利用相位置乱的数据丢失情况相比，采用该方法获得的结果有很大的改进。这种技术可以很容易地用于在不可靠的网络上传输视频片段。

Multiple Description Coding Of Video Using Phase Scrambling

In this paper, we proposed a method to decrease the effects of data loss in communication of a video sequence using phase scrambling. Phase scrambling is used to spread the data of each pixel of a video sequence over all pixels of the scrambled video. In our experiments we studied the effects of different loss patterns. The results obtained by employing this method shows great improvements compared to cases of data loss without exploiting phase scrambling. This technique can be readily used in transmission of video segments over unreliable networks.
