Abstract
The video signal processor 10 includes a chain detector 16 which uses features extracted from visual and/or audio segments divided from an input stream of video data, and a criterion for determination of similarity between visual and/or audio segment pairs, calculated for each of the features using the similarity determination criterion, to detect similarity chains each composed of a plurality of visual and/or audio segments similar to each other from the visual and/or audio segments, and a chain analyzer 18 which analyzes the similarity chains to determine and output local and/or global video structures of the video data.
