ABBREVIATED REPRODUCING METHOD OF CONTINUOUS MEDIA DATA, ABBREVIATED REPRODUCING METHOD AND APPARATUS OF COMPOSITE MEDIA DATA, PROGRAM, AND COMPUTER READABLE RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To enable highly compressed abbreviated reproduction, while maintaining comprehensiveness so that a user can observe and search contents in a short period of time. SOLUTION: The invention includes the process steps of: dividing input continuous data into frame sections; calculating the change amount of a feature parameter of each frame section; extracting a frame in which the change amount of the feature parameter is larger than a predetermined value; clustering the extracted frame; calculating the change amount of a cluster unit which is clustered; restructuring the data by linking only clusters in each of which the change amount of the cluster unit is larger than a predetermined value; and outputting the linked restructured data.
