The MPEG Video Compression Standard
The Motion Picture Experts’ Group was assembled by the International Standards Organization (ISO) to establish standards for the compression, encoding, and decompression of motion video. MPEG-1 [IS92b] is a standard supporting compression of image resolutions of approximately 352×288 at 30 fps into a data stream of 1.5 Mbps. This data rate is suitable for pressing onto CD-ROM. The MPEG-2 standard [IS93b] supports compression of broadcast television (704×576 at 30 fps) and HDTV (1920×1152 at 60 fps) of up to 60 Mpixels/sec (appx. 700 Mb) at compression ratios of roughly three times those expected of moving JPEG [IS92a] (playback rates of up to 80 Mbps).
