Chapter 2 introduced some important aspects of analogue and digital video, particularly relevant to video compression. In this chapter we have a first look at some basic video compression techniques before we move on to specific MPEG algorithms. Although some of the examples are already based on MPEG-2 coding tools, the principles explained in this chapter are applicable to the majority of video compression algorithms in use today. But before we explore the vast area of video compression methods, we will have a brief look at audio compression techniques.
