Video Compression
Abstract
Video compression can be viewed as image compression with a temporal component since video consists of a time sequence of images. From this point of view, the only “new” technique introduced in this chapter is a strategy to take advantage of this temporal correlation. However, there are different situations in which video compression becomes necessary, each requiring a solution specific to its peculiar conditions. In this chapter, we briefly look at video compression algorithms and standards developed for different video communications applications.
