METHOD FOR TRANSMITTING SIGNALS WHILE REDUCING THE NUMBER OF SIGNAL LINES BETWEEN TELEVISION CAMERA AND IMAGE DEVICE, AND APPARATUS USING THE SAME

摘要

PURPOSE: A method for transmitting signals between a television camera and an image device, and an apparatus using the same are provided to reduce the number of signal lines of a cable and reduce a diameter of a cable, thereby photographing an image on flexible photographing conditions. CONSTITUTION: A first time division multiplexing circuit(200) multiplexes a video signal and a first control signal from a television camera to generate a first serial signal. The first serial signal is transmitted by using a first signal line in a transmission cable(11). A second control signal from the television camera is transmitted to an image device by using a second signal line in the transmission cable. A first demultiplexing circuit(191) demultiplexes the first serial signal into the video signal and the first control signal. A third control signal from the image device is transmitted to the television camera by using third and fourth signal lines in the transmission cable.
