Description: The term used for digital video compression standards and file formats developed by the Moving Picture Experts Group. Files in MPEG format generally produce better-quality video than other similar file formats. MPEG files have a high compression rate because they store only the changes from one frame to another, instead of each frame. Some data is removed, but the data that is lost is usually imperceptible to the human eye. The video information is encoded using a technique called DCT. MPEG files can be decoded with software or special hardware. The three major MPEG standards are MPEG-1, MPEG-2, and MPEG-4.
