摘 要
就DVBoverIP的网络电视传输,提出了一种针对传输流的不等差错保护算法,还提出了一种新的视频质量评估标准——预期受损条块数和基于该评估标准的一种数据交织策略,实验结果表明,该算法有效地提高了视频传输的可靠性,减少了网络丢包对视频质量的影响。

An Unequal Error Protection Method for Transport Stream

()

Abstract
In this paper a new unequal error protection method for IPTV transport stream is introduced. We also proposed a new evaluation standard (ENCS), and based on ENCS, a new interlacing strategy. It efficiently improved the transportation reliability over packet-loss network, and reduced the impact from packet loss on video quality.
