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.
