数字视频压缩已成为一种几乎在各种类型的视频应用中都非常重要的技术。随着媒体融合的趋势不断发展,压缩和互操作性能将变得越来越重要。DVD、HDTV、视频电话/电信会议和最近出现的视频监视系统是最著名的几个数字视频应用。不过,这些产品的系统级技术各有不同的历史背景,因此,需要采用不同的压缩算法。 Digital video compression has become a technology that is very important in almost every type of video application. As media convergence continues to evolve, compression and interoperability will become more and more important. DVD, HDTV, video phone / teleconferencing and the recent emergence of video surveillance systems are some of the most famous digital video applications. However, system-level technologies for these products each have a different historical background and therefore require different compression algorithms.
