All current video coding standards are motion-compensated video coders (MCVC’s), where the current frame is predicted using a previously reconstructed frame and motion information, which needs to be estimated. The most common approach to exploit the temporal redundancy is motion-compensated prediction. MPEG-2 bit stream is basically just a series of coded frames one after the other. There are headers and time stamps to help decoders align audio and scrub through the bit stream, but those details are not important to understand the basic coding techniques. What follows is a brief description of MPEG-2 compression techniques without focusing on the exact specification of the bit stream, standard format used for satellite TV, digital cable TV, DVD movies, and HDTV. In addition, MPEG-2 is a commonly used format to distribute video files on the internet.
