されるようになされた信号分配装置。[Claims for Utility Model Registration] n channels of input signals consisting of a video signal and an accompanying audio band signal are prepared, and the signal of any one of the n channels of input signals is The input signal of each channel is supplied to a modulator, and in each modulator, the audio band signal is frequency modulated and mixed with the video signal. , this mixed signal is frequency modulated with a carrier having a frequency different from the carrier frequency of the frequency modulation of the audio band signal, and this frequency modulated input signal of each channel is sent from each of the modulators to a signal distribution circuit,
In this signal distribution circuit, the modulated signals of each channel are respectively pulsed, and the pulsed signals of all channels are supplied to the digital multiplexer of each channel by the signal selection signal.
A signal distribution device configured to extract a signal from any one of the channels.
