MPEG Codec

MPEG video generally refers to a set of standards and methods for compressing audio and video data.  The most important and widely used standards include MPEG-2, an older format currently used by over-the-air digital television providers (digital cable, satellite) and MPEG-4, which includes additional features for digital rights management and support of higher-efficiency standards used by streaming media, HD DVD and Blu-Ray.  MPEG-4 supports interactivity and has the ability to crunch massive video files into pieces small enough to send over mobile networks.  Within MPEG-4 standards are two very popular formats utilized for broadband video delivery: H.264 and MP4.
