MPEG-1
MPEG-1 defines a group of Audio and Video (AV) coding and
compression standards agreed upon by
MPEG (Moving Picture Experts Group). MPEG-1 video is used by the
Video CD (VCD) format and less commonly by the
DVD-Video format. The
quality at standard VCD
resolution and bitrate is near the quality and performance of a
VHS tape. MPEG-1, Audio Layer 3 is the popular audio format known as
MP3. As cheaper and more powerful consumer decoding hardware became available, more advanced formats such as
MPEG-2 and
MPEG-4 were developed. These newer formats are more complex and require more powerful hardware, but the formats also achieve greater coding efficiency, i.e., quality per bitrate.

Moving Picture Experts Group
For the Motion Picture Editors Guild also known as the MPEG, see
Motion Picture Editors Guild. The Moving Picture Experts Group, commonly referred to as simply MPEG, is a
working group of
ISO/
IEC charged with the development of video and audio encoding standards. Its first meeting was in May of 1988 in Ottawa, Canada. As of late 2005, MPEG has grown to include approximately 350 members per meeting from various industries, universities, and research institutions. MPEG's official designation is
ISO/IEC JTC1/SC29 WG11.

Moving Picture Experts Group
Die Moving Picture Experts Group (MPEG, engl. „Expertengruppe für bewegte Bilder“) [] ist eine Gruppe von Experten, die sich mit der Standardisierung von
Videokompression und den dazugehörenden Bereichen, wie
Audiodatenkompression oder
Containerformaten, beschäftigt. Umgangssprachlich wird mit „MPEG“ meistens nicht die Expertengruppe, sondern ein spezieller MPEG-Standard bezeichnet.
