摘　　要：随着各种视频压缩标准的制定及计算机硬件、网络技术的发展,视频信息的应用呈现出爆炸式的增长。为了适应用户终端的多样性及网络自身的传输特性,20世纪90年代后期,视频转码成为视频编码领域一个新的研究热点。本文从视频转码的应用、体系结构和关键技术三个方面,回顾近几年来在视频转码方面的研究进展。With the establishment of video compression standard and the development of computer hardware and network technologies, a lot of video related applications come true recent years. In order to adapt to heterogeneous client terminals and transmission characteristic of networks, video transcoding has become a new research topic in video coding area since 1990s. In this paper, we present a survey on video transcoding, including several typical applications, architectures and their key algorithms.
