Apparatus and method for deblocking filtering image data and video decoding apparatus and method using the same

摘要

A deblocking filtering apparatus and method for removing block distortion of a decoded image, and a video decoding apparatus and method using the same. The deblocking filtering method includes extracting parameter information for a plurality of unit blocks in a macro block, from a header of an input current frame, determining whether to perform deblocking filtering, based on the extracted parameter information, and performing deblocking filtering on the macro block according to the determination result.
