Abstract

PURPOSE: To secure the one-touch operation for replacement between the master and the slave screens by giving the channel selection to the tuner which detects the channel of the slave screen and receives the master screen and at the same time giving the channel selection to the tuner to receive the slave screen from the master screen.
CONSTITUTION: Tuning voltage preset circuit 23 operates by operation of channel selection button 1 and via switch circuit 21 and logic sum circuit 22, and tuning voltage (a) is applied to electronic tuner 5 to receive the master screen. And at the same time, reception channel display circuit 24 displays the channel. Then the actuation is given to circuit 21, logic sum circuit 26, tuning voltage preset circuit 27, tuner 12 and channel display circuit 28 through operation of slave screen selection switch 2 button 1. Here change-over switch 25 is switched via master screen change- over switch 3, and as a result the signal of other display circuits 24 and 28 are applied to preset circuits 23 and 27 to give replacement between the screens.
