摘要

分布式视频编码(DVC)作为新一代的视频编码方法正在不断发展,它适用于移动视频、无线摄像机、无线监控网络等新兴应用和服务。与之前的标准如H.264/5、MPEG4、VC1、VP6/7/8/9和AVS1/2相反;DVC的设计是为了具有低复杂度的编码器,甚至以牺牲高复杂度的解码器为代价。虽然早在2002年斯坦福大学和伯克利大学就提出了这个概念,并进行了进一步的研究,但DVC还没有达到可以实际部署的状态。本文重点介绍了DVC编解码器的定量性能评估及其主要瓶颈,这些瓶颈是实际部署的潜在阻碍。

Quantitative performance evaluation of distributed video coding
Distributed Video Coding (DVC) is evolving as next generation video coding method for certain emerging applications and services including mobile video, wireless camera, wireless surveillance networks etc. On the contrary to its predecessor standards such as H.264/5, MPEG4, VC1, VP6/7/8/9 and AVS1/2; DVC is designed to have low complex encoder, even at the expense of high complex decoder. Though concept was developed way back in 2002 by Stanford and Berkeley Universities and further research has been carried out, DVC has not yet reached a state, at which it can be practically deployed. This paper highlights quantitative performance evaluation of DVC codec and its major bottlenecks, which are potential show stoppers for practical deployment.
