MPEG - (Motion Picture Experts Group) - MPEG represents digital video and audio compression standards and file formats formulated by the Motion Picture Experts Group, an international group of industry experts who's aim is/was to standardize compressed moving pictures and audio. They first met as a group in 1988. (Reference.)
DVB-S2 incorporates MPEG video compression technology. (Note - MPEG is a video & audio compression standard while DVB-S is a data transmission standard.) The Moving Picture Experts Group (MPEG) is a working group of ISO/IEC charged with the development of video and audio encoding standards.
MPEG is sufficient for all the major TV standards, including NTSC and HDTV.
MPEG-1 - Standard for coding of moving pictures and associated audio for digital storage media up to about 1.5 Mbps. Its quality is comparable to VHS video (which is what most Americans have in their homes if they use a VCR.) This standard is designed to work at 1.2 Mbps, which is the data rate of CD-ROMs, thus the video could be played from CDs. The quality however is not sufficient for TV broadcast. It may be used by interactive TV content developers for TV stills (shots with no motion.) http://en.wikipedia.org/wiki/MPEG-1
MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a popular audio encoding format. It's the primary audio format used in iPODs.
MPEG-2 - Standard for coding of moving pictures and associated audio, typically using the 4 to 9 Mbps bandwidth range (but can produce data between 1.2 and 15 Mbps.) It provides broadcast-quality video and includes separate specifications for audio and video. This is sufficient for all the major TV standards, including NTSC and HDTV.

MPEG 4:2:2 - Also referred to as Studio MPEG, Professional MPEG and 442P@ML. www.digitalpreservation.gov/formats/fdd/fdd000034.shtml
MPEG-7 - Short for Multimedia Content Description Interface. It's a
way of attaching meta-data to
MPEG-4 AVC - (a.k.a. H.264) - AVC stands for Advanced Video
