Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To simplify wiring by interconnecting plural cameras and a switcher with one cable, even when the number of cameras is plural cameras are in existence. SOLUTION: In the case that a video changeover control switch section 33 of a switcher 3 outputs a control signal for selecting a video image of, e.g. a camera 1a, the signal is given to a frequency converter, where the frequency is converted and the signal is transmitted to a video cable 2, while being frequency-multiplexed. The control signal is extracted by a band-pass filter of the camera 1a, demodulated by a demodulation circuit and restored to an original signal and the signal turns on a transistor(TR) to set an output impedance only of the camera 1a to be 75 ohms. Thus, only the video signal of the camera 1a is given to the switcher 3 via the video cable 2.  The signal of a control operation section 32 is given to the frequency converter 36, where the frequency is converted and transmitted to the video cable 2 through frequency- multiplexing to control a lens 11 of the camera 1a.
