摘要：

The effect of cell loss on ATM video is investigated. It is shown that the quality of affected pictures mainly depends on the position of the lost cells in an image sequence. Picture degradation at scene cuts is much more objectionable than in areas without scene cuts. The effect of such degradation may last for more than 5s, requiring either a lightly loaded network, or video codecs that can tolerate high cell loss rates.
