Significant progress in digital audio/video processing and communication technology has enabled the dream of many applications such as High-Definition Television (HDTV) broadcasting, digital versatile disk (DVD) storage, high-quality real-time audio/video streaming over various networks, and recent 3DTV. Among these technologies, digital audio/video coding or compression technique has assumed an important role to bridge the gap between huge amount of video data required for the transmission/storage and limited bandwidth of communication channels or limited size of storages. For most applications, a huge number of receivers are used. Therefore, the multimedia standards including audio/video/image coding standards are needed and they are very important for the multimedia industry.
