Abstract
In this chapter, we will discuss some of the basic concepts used in data compression, including video and image compression. Up until now, we have considered only uncompressed video formats, such as RGB or YCrCb, where each pixel is individually represented (although this is not strictly true for 4:2:2 or 4:2:0 forms of YCrCb). However, much greater levels of compression are possible with little loss of video quality. Reducing the data needed to represent an individual image or a sequence of video frames is very important when considering how much storage is needed on a camera flash chip or computer hard disk, or the bandwidth needed to transport cable or satellite television, or stream video to a computer or handheld wireless device.
