REAL TIME LOSSLESS COMPRESSION AND RESTORATION METHOD OF MULTI-MEDIA DATA AND SYSTEM THEREOF

摘要

The present invention relates generally to a method for lossless data compressing and decompressing. Specifically, this invention relates to a system and a method for real-time lossless multimedia data compressing and decompressing for transmitting data over Internet having an unstable bandwidth. A moving picture data is transformed into a joint photographic experts group (JPEG) code via a hardware and a voice/video synthesis rate is controlled based upon a client's network data transmit capacity. A certain amount of data bit stream is classified with the bit unit and a bit group is formed. The data is compressed via replacing each bit group with "1" or "0" and the compressed data is decompressed via inverse-replacing. A certain amount of data bit stream is divided in a certain number of bits. A bit group is formed, each group is replaced with "1" ("1" or "0") and is decompressed into original status of the data.
