Two stage deblocking filtering apparatus based on macroblock

摘要

PURPOSE: A two stage deblocking filtering device based on a macroblock and a method thereof are provided to perform two stage deblocking filtering of SVC(Scalable Video Coding) immediately after each macroblock is decoded. CONSTITUTION: A secondary deblocking filtering unit(120) determines a boundary side of a block and an adjacent block as a secondary deblocking filtering area in a current macroblock. The boundary side of the block is located in the slice boundary of some adjacent macroblocks. The adjacent block does not need to pass a secondary deblocking filtering process. Some adjacent macroblocks include a left macroblock, an upper left macroblock, and an upper macroblock in a current macroblock. The second deblocking filtering unit performs secondary deblocking filtering in the determined secondary deblocking filtering area.
