Abstract
In recent years, the demand has been growing for multimedia archive systems that recognize the need for contents sharing and allow the secondary use of contents. This paper shows a method for constructing a future archive system that will allow a user to generate secondary contents by combining primary contents as desired through time-based editing. This method will also simplify contents management on the system side and provide for expansion of scale. The following new techniques supporting the secondary use of contents are reported here: (1) a composite-drive method that enables high-speed access through the dynamic and static use of optical media in a RAID configuration; (2) a storage-arrangement method for the initial parts of video segments that increases the simultaneous use of the archive system and the number of stored video segments; (3) a method of arranging media units (multiple media in a RAID configuration) on the basis of housing slots; and (4) methods of creating, storing, and searching for secondary contents through time-based editing centered around primary contents.
