以下本発明の一実施例について図面とともに説明する。When viewing a television receiver, there are cases where it is desired to alternately view images from two channels, but in this case, it is necessary to press the push buttons for the two channels alternately, which makes the operation extremely tedious. Therefore, the present invention aims to provide a television receiver that can alternately select two channels with a simple operation.
An embodiment of the present invention will be described below with reference to the drawings.

号が記憶される。As shown in the figure, a signal representing a channel number transmitted from an oscillator 1 of a remote control device is received by a receiving circuit 2 and applied to a channel switching signal discriminating circuit 3. The signal indicating the channel number discriminated by the channel switching signal discriminating circuit 3 is stored in one memory circuit of a memory device 5 having two memory circuits. When another channel number signal is oscillated by the oscillator 1, it is stored in the other memory circuit of the memory device 6 in the same manner. Now, when a signal from one of the memory circuits of the memory device 5 is applied to the channel selection circuit 6 through the instruction execution circuit 4, by operating one specially provided switch provided in the oscillator 1. When the switching signal is transmitted, this switching signal passes through the receiving circuit 2 and the channel switching signal determination circuit 3 and enters the instruction execution circuit 4, which controls the output of the storage device 6 to be switched from one storage circuit to the other storage circuit. do. As a result, all channels of the other channel can be tuned. By operating a specially provided switch on the oscillator, all two channels can be alternately selected. In this case, when a signal of another channel is transmitted from the oscillator 1, the signal of the oldest channel is erased from the storage circuit of the storage device 6, and a new channel number is stored.

ンネルを交互に視聴することができる。As described above, the present invention provides two memory circuits for storing two channel numbers, and switches the outputs of the two memory circuits according to a switching signal generated by operating one switch to select one of the two channel numbers. The feature is that one of the channel numbers is added to the channel selection circuit, and the two channels can be viewed alternately by operating a single switch.
