Abstract

PURPOSE: To obtain a device which is capable of switching between the channel under being selected and the program on the different channel through one-touch operation by installing the ratch means to ratch two units of the control signal plus a simple circuit containing the means to transfer the control signals at the channel selection device to be used to the TV and radio receivers or the like.
CONSTITUTION: Channel selection circuit 1 is installed to switch the selection channels via the digital control signal, along with input circuit 7 which supplies the digital control signals for the switching signals to be supplied to the new channel to transfer control circuit 11 and then supplies the inversion control signals indicating the exchange inversion between the channel being under selection and the channel of memorized different program. In addition, 1st and 2nd ratch circuits 5 and 6 are provided to ratch the control signals for channel switching of circuit 11. Thus, the control signals are written into circuit 5 when the control signal of the new channel is supplied from circuit 7, and then control signals are written by mutual switching between circuit 5 and 6 through control of circuit 11 when the control signals for channel inversion are supplied.
