Abstract In order to supply a volume of digital video content in the digitalization of broadcasting, it is necessary to realize a method of storing a large number of videos and of high‐speed content retrieval. This paper describes a petabyte (1015 power) large‐capacity video archive system and its retrieval method. The archive system employs an automatic magnetic tape feed robot that can accommodate 7200 tapes (15,000 hours) in its center, and an HDD server and a DVD server respectively for each purpose, thus making the efficiency of storage and distribution better and realizing retrieval, video delivery, and remote editing from remote sites. Further, a method of detection of scene change points in a video sequence, a method of browsing video production based on the detected scene change points, and a method of visual retrieval by simultaneous playback representation of multiple videos on a screen are also included. In this paper, a large‐scale archive system that has an automatic tape feed robot at its center and a high‐speed and efficient method of retrieval of the target video using the real‐time playback representation of multiple videos are presented. © 2002 Wiley Periodicals, Inc.
