    Patent number: 4991019
    Abstract: In a digital video signal processing system disclosed, a plurality of programmable processor units (21(01) to 21(16)) each receive two different video signals, process the video signal in accordance with a program, and output the result of the signal processing. A network section (20) receives the output data signals from the plurality of programmable processor units (21(01) to 21(16)) and a plurality of video signals (A1, A2) from exterior, and supplies the received signals to the plurality of programmable processor units (21(01) to 21(16)), and leadouts any one of the produced signals or input video signals. The network section (20) is capable of freely altering a connection pattern of the plurality of programmable processor units (21(01) to 21(16)). The programmable processor units (21(01) to 21(16)) may have signal processing functions as defined by applied programs.
