Abstract

A video coding technique aimed at compression of video and its associated audio at about 1.5 Mbits/s has been developed by the Moving Pictures Expert Group (MPEG-Video). The Moving Pictures Expert Group is part of the ISO-IEC JTC1/SC2/WG11, an organization responsible for the standardization of coded representation of video and audio for information systems. The video compression technique developed by MPEG covers many applications from interactive systems on CD-ROM to delivery of video information over telecommunications networks. The MPEG video compression algorithm relies on two basic techniques: block based motion compensation for the reduction of the temporal redundancy and transform domain based compression for the reduction of spatial redundancy. Motion compensation techniques are applied with both predictive and interpolative techniques. The prediction error signal is further compressed with spatial redundancy reduction (DCT). The quality of the compressed video with the MPEG algorithm at about 1.5 Mbits/s has been compared to that of consumer grade VCR's. The quality, cost and features of the MPEG video algorithm make it directly applicable to personal computers and workstation thus allowing the development of many new applications integrating video, sound, images, text and graphics.
