Since 1980, new video codecs have been created that produce low data rates while preserving the integrity of raw visual data. Videos are typically kept on general-purpose computers and a variety of portable devices. The amount of capacity required to store raw video data in those devices is enormous. As a result, video compression is a fascinating and important issue. There are two types of compression methods: lossy and lossless. Lossy compression is a method of increasing compression efficiency by losing image and video quality. The preservation of the original data is more important than compression performance in some applications; this is where lossless compression comes in. As a result, this book concentrates on lossy compression. Furthermore, motion estimation and compensation are thought to be important.
