ABSTRACT:
A multimedia data reproduction apparatus comprising an optical disk library containing a plurality of optical disks and a plurality of optical disk drives, a file management unit for managing names of motion picture files stored in the respective optical disks, a media management unit for managing whether each of the optical disks is being used or not, a drive management unit for managing whether each of the optical disk drives is being used or not, an open processing unit for deciding whether to accept a request to start reading or reject it according to information from the file management unit, media management unit and the drive management unit, a close processing unit for performing close processing of a motion picture file for which a request to end reading is issued, a data readout control unit for reading motion picture data in response to the request to start reading, and a network control unit for controlling communication between the above-mentioned units and terminal PCs 20. In this apparatus, it is possible to continuously reproduce motion pictures from the optical disk library.
