Abstract: When an automatic programming process for searching receivable channels and presetting the receivable channels is executed or when an automatic erasing/adding process for adding or erasing a set channel is executed, a video signal of a master picture plane is muted by a muting circuit 20. A source selector switch 12 is switched so as to display a picture plane of the reception channel onto a slave picture plane. When the automatic programming process or automatic erasing/adding process is executed, since the video signal of the master picture plane is muted, a display signal is generated by a horizontal pulse and a vertical pulse in a free-run state. Thus, the display is stabilized. Even during the execution of the automatic program or automatic erasing/adding process, the video image of the channel which is being received can be confirmed by the slave picture plane.
