14.2. Multimedia Algorithms

In this section, we study the basic characteristics of some multimedia applications. We start with video compression, the dominant digital video application today. We then look at a next-generation smart camera application.

14.2.1. Compression

Video compression has been developed over the last 30 years and is now a mass-market item. Satellite television, terrestrial digital television, digital video cameras, and personal video recorders all make use of video compression methods.
