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.
Of all the different sources of data, perhaps the one that produces the largest amount of data is video. Consider a video sequence generated using the ...
