PICTURE TRANSMISSION SYSTEM

摘要

PROBLEM TO BE SOLVED: To simplify signal level regulation of a video signal in a reception terminal. SOLUTION: Variation width of signal level of a video signal received by each reception terminal 3 is suppressed by regulating the gain of a relay amplifier in a transmitting section 15 at a control section 1 such that the signal level of a video signal relayed to the reception terminal 3 falls within a predetermined range. As a result, regulation of signal level of the video signal in the reception terminal 3 (gain regulation of a reception amplifier) can be simplified. Furthermore, wiring length of a signal line Ls from a main unit 1 to the reception terminal 3 can be extended depending on the gain regulation function of the reception amplifier in the reception terminal 3, or the type of transmittable wiring configuration can be increased.
