ければならない。By the way, nowadays, when satellite broadcasting is developed, a satellite broadcasting receiving tuner (hereinafter referred to as a BS tuner) is built in, and a satellite broadcasting signal is directly inputted from an antenna. VTRs that have been created have appeared, but VTs that do not have a built-in BS tuner
In the first place, R does not have means for selecting a satellite broadcasting station, so this is directly used by a TV with a built-in BS tuner.
Even if you connect to, if you want to select and record satellite stations,
It is necessary to operate the TV and the VTR respectively at desired recording times so that the video signal of the TV is input to the VTR.

(Step S12). After this, turn off the VTR power
Infrared data for transmission is transmitted (step S13), and the reference signal and the VTR video signal are compared (step S14). Here, if the output of the video signal comparison unit 6 is a signal indicating a match, the infrared data for turning off the VTR power supply is transmitted again (step S13), and if the output of the video signal comparison unit 6 becomes a signal indicating a mismatch. , The output of the switch A3 is switched to the tuner output (step S15).
