摘要

丢失或解码错误的帧会降低视频的呈现质量(QoP)，这可以通过正确解码帧的数量来方便地测量。我们证明了帧完成率(CR)不能很好地代表MPEG视频的QoP。然后，我们提出了一个新的QoP度量和一组在线调度算法，以实现更好的QoP，特别是对于过载系统。

QoP-driven scheduling for MPEG video decoding

Dropped or incorrectly decoded frames degrade a video's quality of presentation (QoP), which can be conveniently measured by the number of correctly decoded frames. We demonstrate that the frame completion ratio (CR) does not represent well the QoP of an MPEG video. We then propose a new QoP metric and a set of online scheduling algorithms that achieve better QoP, particularly for overloaded systems.
