摘要

视频源编码和传输都可能导致视频内容失真，而这两种失真通常是相互影响的。为了获得最佳的视频传输质量，它们之间有一个基本的权衡。分析了源编码失真和传输失真对视频质量的影响，提出了一种基于喷泉码和不等保护的视频传输方案。提出了一种速率失真模型，用于构建带宽有限网络下的视频传输系统。研究了可扩展视频编码不同层的不均等保护问题，提出了一种确定视频编码源率和各层冗余量的算法。实验结果表明，采用该方法可以获得最佳的视频传输质量，并能显著降低视频传输失真。

A Novel Approach to Joint Source-Channel Coding for Scalable Video Transmission

Video source coding and transmission may both cause distortion of the video content, and these two types of distortions usually influence each other. There is a fundamental tradeoff between them for achieving the best video transmission quality. We analyze the effect of the source coding distortion and transmission distortion to video quality, and propose a video transmission scheme based on fountain code and unequal protection. A rate distortion model is presented to formulate the video transmission system in a bandwidth limited network. The unequal protection for different layers of scalable video coding is investigated, and an algorithm that can be used to determine the source rate of the video coding and the redundancy amount assigned to each layer is proposed. The experimental results show that, using this method, the optimal quality of video transmission can be achieved and the distortion of the video transmission can be reduced dramatically.
