分布式视频编码(Distributed Video Coding,DVC)是一种新颖的视频压缩方法,具有极低的编码复杂度和良好的抗噪声鲁棒性。为了使人们对该编码方法有所了解,该文首先详细介绍了分布式视频编码的理论基础和特点,然后讨论了分布式视频编码的两大关键技术,包括编码端高效压缩和解码端边信息(side information)插值;最后总结分析了分布式视频编码在低复杂度编码和视频信号鲁棒传输等两大应用领域的研究现状,并对其研究前景进行了探讨。
Distributed video coding is a new paradigm for video compression, with low encoding complexity and robustness to channel losses. In this paper, principle and characteristics of distributed video coding is firstly introduced, followed by two key techniques including highly effective compression and interpolation of side information. Then, recent development of the research on two main application areas of distributed video coding is reviewed, along with the future trends of distrib- uted video coding.
