什么是MPEG? MPEG,确切地称之为动态图像压缩编码标准,MPEG是Moving Picture Ex- press Group(活动图像专家小组)的缩写,这个小组成立于1988年,主要任务是要建立一个标准,将数字视频应用在电视系统中。概括地说,MPEG图像压缩的原理是利用了图像中的两种特性：空间相关性和时间相关性。这两种相关性使得图像中存在着大量的冗余信息。如果我们能将这些冗余信息去除,只保留少量非相
What is MPEG? MPEG, exactly what we call the Motion Picture Compression Coding standard, and MPEG is an acronym for Moving Picture Ex- press Group, which was established in 1988 with the main task of creating a standard that will Digital video applications in television systems. Broadly speaking, the principle of MPEG image compression takes advantage of two characteristics of the image: spatial correlation and temporal correlation. Both of these correlations result in a large amount of redundant information in the image. If we can remove these redundant information, only a small amount of non-phase remains
