In a VTR, etc. that has a built-in F signal distribution circuit, when the power of the VTR, etc. is on, the first and second switches are respectively switched to the second position, and the RF signal input is sent to the distributor via the first switch. The RF signal is divided into two by the same distributor, and the first RF signal divided into two is coupled to the tuner built in the VTR etc., and the second RF signal is divided into the second RF signal.
When the power of the VTR, etc. is on and the RF modulator built in the VTR, etc. outputs a modulated signal, the first and second switches are respectively switched to the third position. The RF signal input is coupled to a distributor via the first switch, the RF signal is divided into two by the distributor, and the first RF signal divided into two is coupled to a tuner built in the VTR or the like. and outputting the modulated signal output of the RF modulator via the second switch, and when the power source is off, the first and second switches are respectively switched to the first position, and both switches are connected in cascade. An RF signal distribution circuit characterized in that the RF signal input is configured to output the RF signal input without passing through the distributor.
