To improve the end-to-end QoS guarantee for video applications, this paper presents a content-aware packet scheduling scheme for the pre-encoded video over wireless networks. The scheme can be used with the wireless standard such as HSDPA. A distortion based estimation method (EM) is proposed to measure the contribution of each packet in terms of received quality, with the packet quality contribution index (PQCI). We consider both the complex error concealment techniques and the quality distortion, made for current frame and the frames related with it. Simulation results show that the proposed EM scheme provides a viable and useful approach for pre-encoded video streams and it can significantly outperform other existing algorithms.
