    摘要： A storage system for reading and storing I and B compressed video frames while improving fast video data reproduction. The system includes a storage disk, a read/write head, and a controller for positioning the I and B frames on the disk. The I frames may be stored on a first cylinder while the B frames are stored on a second cylinder. Alternately, the I frames may be stored on a plurality of cylinders. Thus, in the high-speed video reproduction mode, the controller can move the head to sequentially read I frames in the order which the I frames were stored on the plurality of cylinders. Further, the controller may move the head to sequentially read I frames stored on only one of the plurality of cylinders. In the normal video reproduction mode, a first I frame is read, followed by a B frame associated with the first I frame before proceeding to subsequent I frames. A buffer temporarily stores data read from the storage device. The buffer has a capacity equal to or greater than the capacity of two cylinders to ensure that normal video reproduction is not slower than that which is performed conventionally.

    摘要： The invention uses a storage device effectively to supply data to as many user terminals as possible. Sub-control units read unit data in which dynamic image data having continuity is divided and compressed from storage devices sequentially according to the tokens stored in queues of a system control unit, and supplies buffers corresponding to storage devices through a change-over switch for connection corresponding to the tokens. The unit data stored in the buffers is supplied to terminals as analog data of dynamic image through expanders and D to A converters. Therefore, the unit data from K units of storage devices to M (K * N) units of terminals at the substantially same time.
