摘要

本文提出了一种在支持qos的网络上传输立体H.264/MVC视频的速率失真优化框架。通过综合分析的方法计算每个编码单元损失引起的失真，然后在速率失真优化框架内使用该方法来选择最佳传输策略。仿真结果表明，相对于参考先验优化策略，所提出的速率失真优化策略显著提高了通信质量。

Rate-distortion optimized H.264/MVc video communications over QoS-enabled networks

This paper presents a rate-distortion optimized framework for the transmission of stereoscopic H.264/MVC video on QoS-enabled networks. The distortion caused by the loss of each encoding unit is computed by means of the analysis-by-synthesis approach, which is then used within a rate-distortion optimization framework to select the best transmission strategy. Simulation results, evaluated using an objective quality measure accounting for the peculiarities of the human visual system in stereoscopic video quality perception, show that the proposed rate-distortion optimized strategy significantly improves the communication quality with respect to a reference a priori optimization strategy.
