In the second microcomputer 17 of the VCR 2, the TV 1
Based on the channel information transmitted from the first control input / output terminal 10 via the control line, the control signal is converted into necessary control data to control the second tuner 15. When the transmitted channel information is a channel number, the second microcomputer 17 converts it into tuner control data corresponding to the reception channel and controls it.

Since the reception frequency is the reception frequency data of the frequency synthesizer system, the reception frequency data is converted into an integer value of the frequency division ratio of the frequency synthesizer IC to control the tuner. If the data to be transmitted is frequency division ratio data, this conversion is not necessary and can be directly controlled.
