Patent ID: 7388915

Claim:
A video data coding/decoding apparatus comprising: an encoder dividing a partition partitioned by a data partitioning technique into certain blocks, channel-coding the divided block data and transmitting a bit stream, the encoder inserting channel coding information into the partitioned data, the channel coding information including size information of each of the plurality of partitions, wherein the inserted channel coding information relates to an index of a channel coding rate table (CCRT); a decoder channel-decoding the bit stream received from the encoder so as to restore a video data, wherein the encoder comprises: a variable length coder source-coding the video data, partitioning it into a plurality of partitions, and dividing each partition into certain blocks, a channel coder channel-coding the partition data of the divided block, and a partition mixer mixing a partition table storing the size information of the plurality of partitions and the plurality of partitions, so as to form the bit stream, and wherein the bit stream comprises: a slice start code (SSC), the partition table storing the size information of each partition, a first partition including a header portion having the information bits of the channel-coded video data, a second partition having motion vector (MV) information, a third partition having a discrete cosine transform (DCT) coefficient, and a zero-bit inserting unit for byte-alignment.
