Stands for "Moving Picture
Experts Group."
The MPEG organization, which works with the International Organization
for Standardization (ISO), develops standards for digital audio
and video compression. The group constantly works to develop
more efficient ways to digitally compress and store audio and
video files.
The term MPEG also refers to a type of multimedia file, which
is denoted by the file extension ".mpg" or ".mpeg."
These files are compressed movies that can contain both audio
and video. Though they are compressed, MPEG files maintain
most of the original quality of the uncompressed movie. This
is why many videos on the Web, such as movie trailers and
music videos, are available in the MPEG format.
