Each operating circuit outputs a modulated control signal of a carrier frequency higher than the frequency of the video signal, to a circuit portion connecting the distributing device to the displaying devices. The television camera also includes a driving circuit which receives the control signals, extract a separated control signal, demodulates and decodes the extracted signal and operates the television camera based on the decoded control signal.
