For an MPEG coding scheme, the encoder can do more than video compression. In this paper, a novel MPEG codec embedded with scene-effect information detection and insertion is proposed to provide more functionality at the decoder end. Based on the macroblock (MB) type of information that is generated simultaneously in the encoding process, a single-pass automatic scene-effect insertion MPEG coding scheme can be achieved. Using the USER_DATA of picture header, the video output bitstreams by ourdoi:10.1109/tmm.2005.850961 fatcat:gbkuhbwzxffkrmkwhu7pq7j2na
