MPEG stands for Moving Picture Experts Group. The name was given to the International Standards Organization (ISO) committee that specified a standard compression, transmission, and decompression scheme for video. Today MPEG refers to a series of standards documents officially known as ISO/IEC 11172 (MPEG-1) and ISO/IEC 13818 (MPEG-2). MPEG actually specifies the syntax of the compressed video and audio bitstreams, which enables a great deal of flexibility at the encoder.
