In this paper we propose and implement an efficient scheme for automatically detecting the abrupt shot changes in a video stream compressed in MPEG video format. In the proposed scheme, the type of each macroblock in a B-frame is compared with the type of corresponding macroblock (<italic>i.e.</italic> the macroblock in the same position) of the previous(More)
