In this chapter, we show the demands of video compression and introduce video coding systems with state-of-the-art signal processing techniques. In the first section, we show the evolution of video coding standards. The coding standards are developed to overcome the problems of limited storage capacity and limited communication bandwidth for video applications. In the second section, the basic components of a video coding system are introduced. The redundant information in a video sequence is explored and removed to achieve data compression. In the third section, we will introduce several emergent video applications (including High Definition TeleVision (HDTV), streaming, surveillance, and multiview videos) and the corresponding video coding systems. People will not stop pursuing move vivid video services. Video coding systems with better coding performance and visual quality will be continuously developed in the future.
