Digital Video Compression
Video coders compress a sequence of images, so this chapter is closely related to Chapter 9 on image compression. Many of the techniques introduced there will be used and expanded upon in this chapter. At the highest level of abstraction, video coders comprise two classes: interframe and intraframe, based on whether they use statistical dependency between frames or are restricted to using dependencies only within a frame. The most common intraframe video coders use the DCT and are very close to JPEG; for video, they are called M-JPEG, wherein the “M” can be thought of as standing for “motion,” as in “motion picture.” Also, common intraframe video compression is the DV coder in standard-definition video camcorders. ...
