Apparatus using the method flag encoding method, and a flag decoding method,

摘要

Flag coding apparatus and method using a spatial relationship between the various flags included in the macroblock coding efficiently is provided. And generating a flag bit string by collecting a flag value assigned to by the block by the spatial relationship of the predetermined block, a method for encoding a flag used in coding comprises video frames in a plurality of blocks, wherein A method for setting a pattern bit indicating the steps of dividing a group of a predetermined size bit string, bits included in the bit string that is the divided whether all zero, bit string that is the divided by a pattern bits the set including the steps of entropy coding.
