Abstract

PURPOSE:To switch an audio input switching circuit and a video input switching circuit each other automatically through mode switching, by providing a mode switch at a channel switching-operating section. CONSTITUTION:A channel switching section 11 is provided with RF mode switches SO1-SOn corresponding to each channel of VHF, UHF and FM record player mode switch S1, audio tape recorder mode switch S2, and VTR mode switch S3. Signal lines L1 and L2 transmitting a digital code signal at input signal switching circuit side are connected to the switches S1 and S2. The switch S3 is connected to the signal lines L1 and L2 via reversing preventing diodes D1 and D2 and a VTR type selection switch S4. Thus, according to the mode switching, a switching code signal is generated to an input switch circuit for terminals (a), (b) of the lines L1 and L2 to switch the input circuits automatically.
