PROBLEM TO BE SOLVED: To extremely simply perform the operation of changing an external input channel. SOLUTION: When an optional key is selected and inputted by operating a remote controller 21 of a video 20 connected to an external input terminal 18 of a television receiver 10, a signal transmitted from the remote controller 21 is retained in a remote controller key memory part 131 in a microcomputer 13 through a receiver 12 of the television receiver 10. After that, when the key selected and inputted from among operation keys of the remote controller of the remote controller 21 is inputted, the signal transmitted from the remote controller 21 is received in the receiver 12 and discriminated whether it matches with the signal held in the remote controller key memory part 131 or not. When it does not match with the signal held in the remote controller key memory part 131, the external input channel is left as it is. However, when it matches the signal held in the remote controller key memory part 131, a multiplexer 14 is activated, and the external input channel is switched so that an output signal of the video 20 is inputted. |
