However the MPEG task is far from limited to compression, but involves media data acquisition, processing, storage, distribution, transmission, protection, the establishment of a series of technical standards. Currently MPEG7 and formulated MPEG4, MPEG21 will for multimedia content-based indexing data compression and the database application provides a more general platform for the next generation, will visual, audio systems and networking applications have far-reaching effects. All things are exquisite a benefit, so this paper mainly studies the development and application of MPEG. This paper firstly define the standard MPEG and analyzes the significance of rese
