The present era, the information technology and the computer Internet rapid development, under this background, the multimedia information has become the humanity to gain the information most main carrier, simultaneously also becomes the electronic information domain technology development and the research hot spot. The multimedia information have easy after digitized processing to encrypt, ant jamming ability strongly, merits and so on renewable relaying, but simultaneously also follows the magnanimous data the production, this proposed to the information storage equipment and the correspondence network requests very high, thus becomes hinders the people effectively to gain and the use information significant bottleneck. Therefore studies the highly effective multimedia data compression code method, reduces the form memory and the transmission digitization multimedia information has the vital significance. As the multimedia technical core and the key, the multimedia data compression code in recent years have all made the considerable progress in the technology and the application aspect, its progress and the consummation are affecting modern society's aspects profoundly.
