METHOD FOR MODELING CODING INFORMATION OF A VIDEO SIGNAL TO COMPRESS/DECOMPRESS THE INFORMATION

摘要

A modeling method for compressing/decompressing coding information of video signals is provided to adaptively perform modeling for binarization using coding information correlated to the coding information of the video signal to improve a data compression rate. A modeling method includes a step of selecting one of a plurality of models to be applied to binarization or inverse-binarization of coding information about an image block on the basis of coding information of a co-located block, which has correlation with the coding information about the image block. The coding information of the co-located block having correlation with the coding information about the image block is identical to the coding information of the image block. The co-located block is adjacent to the left and top of the image block on an image frame decoded prior to the current block.
