    摘要: As to a telecine video signal (Sv), in a telecine video signal detector (Dtp) for detecting a scene-change part (SC) and deciding whether successive telecine conversion has been carried out, a motion detector (3) detects a motion between video signals (Sv) one field apart from each other; a first statistical processing unit (4) accumulates detection results (Sm) for one field; a first telecine decision unit (5) decides whether the field represents telecine-converted video; the second statistical processing unit (6) detects statistical information (Ss2) of the input signal (Sv); a scene-change detector (8) detects a scene-change in the output (Ss2) from the second statistical processing unit (6); a second telecine decision unit (9) decides field continuity from a detection result (Ssc) of the scene-change detector (8) and a result (St1) of the first decision unit (5); and then an AND circuit (10) carries out an AND operation on outputs (St1, St2) from the first and second decision units (5, 9).

    摘要: A data transfer system comprises a plurality of terminals; a plurality of high-speed data transfer units connected to the terminals through a network, each data transfer unit comprising a plurality of storage devices and a storage device group control device or unit for controlling readout of data from the storage devices, and dividing and storing data requested by the terminals; a virtual storage device group controlling device or unit for controlling readout of data from virtual storage device groups, each virtual storage device group being constructed by selecting a storage device from each high-speed data transfer unit; and an instruction conversion unit or device for receiving a data readout instruction on the basis of data requests output from the terminals, which instruction is given to the virtual storage device groups, from the virtual storage device group control unit or device, and converting the instruction into a data readout instruction to the storage devices from the storage device group control unit or device. In this data transfer system, the load for the data transfer processing is equally distributed among the high-speed data transfer units even when data transfer requests are output from plural terminals.
