Abstract

In this work, each packet is associated with a varying degree of significance based on the impact of its loss, which is estimated with a corruption model. For a compressed video stream, initial and propagation errors are first described by the macroblock (MB)-based corruption model by taking into account error concealment, temporal dependency, and loop filtering. Next, at the packet-level, a corruption model using the relative priority index (RPI) is constructed by integrating MB-based models. Furthermore, the effect of multiple-packet loss is analyzed and the associated RPI is calculated to improve the model accuracy at a higher packet loss rate. With the RPI-based corruption model for each packet, coordinated delivery of packetized video over QoS networks is investigated. Finally, a per-packet optimization framework with unequal error protection (UEP) is realized to consider both end-to-end video performance and pricing. The performance of the proposed solution is verified with intensive simulations.
