Short for Moving Picture Experts Group, one of the leading standards for compressing full-motion digital video. Unlike some competing standards, such as Video for Windows, Indeo and QuickTime, MPEG requires special hardware for decompression. However, it produces better results than these software-only solutions.
The most common implementations of the MPEG-1 standard provide a video resolution of 352-by-240 at 30 frames per second (fps). This produces video quality slightly below the quality of conventional VCR videos. A newer version of the standard, MPEG-2, offers resolutions of
720-by-480 at 30Hz. This is sufficient for all the major TV standards, including NTSC.
