Abstract:
In an interlaced picture having a mixture of field structure macroblocks and frame structure macroblocks, a coding distortion removal method removes coding distortion in blocks composing the macroblock. The method removes a coding distortion in a block block which is included in a macroblock of a frame structure, and which is not adjacent to a boundary of a macroblock of field structure. A coding distortion in a block which is included in a macroblock of the field structure, and which is not adjacent to a boundary of a macroblock of the frame structure is then removed, and a coding distortion in a block which is adjacent to both a macroblock of the frame structure and a macroblock of the field structure is removed.
