| Abstract: | According to the multimedia information compression technology, the encoder, decoder and exchange format defined in the JPEG standard for the static image compression, the type of encoding and the structures of encoding based on DCT, no-distortion encoding and entropy encoding are introduced. The MPEG standard for moving video and audio compression as well as the video compress algorithm, and the encoding and the decoding of audio compression is described. In the end, the methods of Huffman statistical compression and LZ78 dictionary compression, and the general ARJ, PKZIP /PKUNZIP and WinZip compression software etc. are presented |
