Abstract

In this research, a video delivery system is proposed by integrating the layered codec and the proposed corruption model. In the system, it is assumed that the base layer packets are delivered without loss since they are assigned the most reliable service level. Then, packets in the enhancement layer are analyzed with the corruption model and categorized for differentiated delivery services. The corruption model for generating the relative priority index (RPI) is extended to layered bitstreams. In addition to taking into account the initial error and the propagation error due to packet loss, the dependency between the same and different layers is reflected in the modified macroblock corruption model. In order to facilitate the prioritized delivery of the enhancement layer, the RPI-based corruption model for each packet as well as coordinated delivery of packetized video over QoS networks are 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 extensive simulations.
