Abstract :
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.
