Paper Abstract

International standards bodies snch as the ISO and CCITT have established various expert groups to standardize compressed digital representations of color image and video signals for different applications. Here we are concerned mainly with the work of the Motion Picture Experts Group (MPEG), whose charter is to specify a generic coded representation of video and audio. The MPEG work has been divided into three distinct phases, the first aimed at compressing low-resolution (1/4 CCIR-601) pictures at data-rates in 1-4 Mbits/sec, the second at compressing full CCIR-6O1 resolution pictures at data-rates in 4-10 Mbits/sec, and the third at compressing HDTV pictures at appropriately higher data-rates.
