Abstract

MPEG video decoding algorithm has been embedded into many consumer electronic products. In this paper, we demonstrate that the completion ratio (CR) does not represent well the quality of presentation (QoP) of MPEG video. We then propose a new QoP metric, which 1) is based on frame completion ratio but 2) differentiates firm and soft deadlines and also 3) considers the frame dependency. We show that, on a set of simulates MPEG movies; the proposed QoP metric measures the QoP of the movies much better than completion ratio. We then present a set of online scheduling algorithms that enhance QoP significantly, particularly for overloaded systems.
