摘要 |
A camera section for photographing an object to generate a video signal is connected via a cable to a video signal processing section that receives and processes the video signal. When the camera section is replaced with a different one, signals corresponding to the new camera section are automatically provided. A video signal, a synchronizing signal therefor, a clock signal, and control data are multiplexed on a signal line in the cable and the signal obtained is transmitted from the camera section to the video signal processing section, and control data is sent from the video signal processing section to the camera section. These control data are transmitted during a vertical interval of the video signal, and a DC voltage is supplied to the camera section from the video signal processing section via a shield line that is paired with the signal line in the cable. <IMAGE> |
