Abrégé
(EN)
An in-house video system comprising a computer (19) having graphics capabilities, a control system (23), a plurality of video cassette recorders (13) and a plurality of display media (17). The computer (19) and video cassette recorders (13) each produce a video signal for display upon the display media (17). The appropriate video signal is transmitted to the display media via the common transmitter line (15) and receiver lines (16). The video signals are displayed in a sequential manner determined by the program of the computer (19) and the operation of the control system (23). The control system (23) comprises a detecting means (27), a timing means (29), an actuating means (31) and a set of relays (25). The detecting means (27) detects the presence or absence of a video signal on the transmission line (15) via line (35) and generates an active signal when no video signal is detected. The timing means times out a predetermined time period upon generation of an active signal and the actuating means (31) actuates the stop and rewind controls of the particular VCR (13) generating the video signal so as to stop and rewind the video cassette tape from which the previous video signal was generated. Thus, the control system ensures that after the playing of a video cassette tape and the display of the video signals derived therefrom from a VCR the tape is wound back to start upon completion of the display from the tape. The computer (19) functions to display computer graphics during the intervening periods between the displaying of the video cassette tapes and also, controls selection of the particular video or VCR which is to play its video cassette tape.
