The present invention relates to a hierarchical hybrid shot change detection
method in MPEG-compressed video circumstances, wherein the method according to
the present invention comprises: detecting a shot change candidate region, by hierarchically
applying a global color distribution difference among the frames by the color histogram;
detecting an abridged shot change candidate region by using the difference of the
global color histogram difference among adjacent I, P frames after additionally
decoding P frames existed in the detected candidate region; decoding B frames within
a abridged shot change detection candidate region at a macro block level in a sequence
of the B frames sharing adjacent two anchor frames; determining a distribution
characteristic of an intra coded block and a reference pattern type of each B frame
in the region; and detecting a hard cut by using the distribution characteristic
and reference type.
