摘　　要：定义了数字电视传送流丢包,并通过实验指出丢包对电视信号有重要影响,建议把定义的丢包率作为评价数字电视信号传输质量的客观指标之一。为此,提出了两种分析丢包和统计丢包率的算法,并进行了实验验证。This paper defines Packet Loss of DTV Transport Stream, through experiments indicates the significant influence of Packet Loss to TV signal and suggests that Packet Loss Rate of DTV TS defined in this paper should be as one objective index to evaluate the transporting quality of DTV signal. Two algorithms are presented and validated through related experiments on how to analyze Packet Loss and count Packet Loss Rate.
