MPEG (pronounced M-peg), which stands for Moving Picture Experts Group, is the name of family of standards used for coding audio-visual information (e.g., movies, video, music) in a digital compressed format.
The major advantage of MPEG compared to other video and audio coding formats is that MPEG files are much smaller for the same quality. This is because MPEG uses very sophisticated compression techniques.
MPEG.ORG is the most complete, comprehensive and up-to-date index of MPEG resources on the Internet. MPEG.ORG is mostly focussing on the MPEG-1 and MPEG-2 standards.

On the Web, MPEG Video files have the extension .mpg and MPEG Audio files generally have the extension .mp2 or .mp3.
DVD (Digital Versatile Disk) is the new type of CD that everyone in the Computer and Multimedia Industry is talking about, even though DVD players and DVD disks have just been introduced on the consumer market and are not widely used yet.
DVD storage capacity (17 Gbyte) is much higher than CD-ROM (600 Mbyte) and DVD can deliver the data at a higher rate than CD-ROM. With the help of MPEG and Dolby compression technologies, a DVD disk can hold hours of high quality Audio-Visual contents. DVD is predicted to be the unavoidable replacement for the old VCR technology. DVD is seen as the ideal replacement support for interactive multimedia applications currently based on the CD-ROM technology.
