Bull, Fan Zhang, in Intelligent Image and Video Compression (Second Edition), 2021 Abstract Read moreÄigital picture formats and representationsÄavid R. Our focus in this presentation will thus be on the MPEG-2 standard. ![]() It has been adopted for video communication applications such as HDTV and DVD. Currently, the most widely used video compression standard is MPEG-2. The main organizations involved in adoption of video communication standards include the International Standards Organization (ISO) and International Telecommunications Union (ITU). Numerous video compression standards have been released by international organizations over the past decade. Representation of video streams in compressed form is therefore required for efficient video communication systems. Moreover, computer processing and memory limitations often impose serious constraints on transmission rates. ![]() Transmission of raw (uncompressed) video streams is impractical: Excessive bandwidth is needed for both the communication channel and storage devices. Video communications usually relies on compressed video streams. Dan Schonfeld, in Handbook of Image and Video Processing (Second Edition), 2005 2.1 Introduction ![]()
