This paper presents a macroblock (MB) type mapping method which considers a subtle difference of skipped-macroblock in MPEG-2 and H.264/AVC. A bitstream compressed by H.264 contains much more skipped- MB than a bitstream compressed by MPEG-2 does since H.264 adopts an improved concept of skipped-MB. Experimental results show that the proposed method takes advantage of the improved skipped-MB of H.264 fully.
