載のテレビジヨン受像装置。[Claims for Utility Model Registration] An input terminal 20 is provided into which a plurality of video signals A each consisting of a television broadcast signal and an output signal of an external video processing device are inputted, and the video signal A is inputted via a mode switching circuit 2. The switching circuit 2 is controlled to be switchable by an information processing circuit 1 connected to the image display device 3 and connected to a mode switching key 40. Video signal A to be connected to display device 3
The controller includes a storage unit that stores a discrimination signal that specifies 0 , a control unit that performs logical operation processing according to a prewritten procedure, and a plurality of ports for input and output. It is determined whether the selected mode selected by operating the mode switching key 40 is one of the reception modes of the video signal A0 connected to the input terminal 20, and when it is the reception mode, the switching circuit In the television receiver, a selection signal C is created for setting the selected mode to approximately the selected mode, and a selection signal C is created for skipping the selected mode to an arbitrary reception mode when the selected mode is in a non-reception mode. A selection signal processing circuit 7 is interposed between the circuit 2 and the input/output port 13 of the information processing circuit 1, and the selection signal processing circuit 7 transmits signals for each selection mode to the input/output port 13 when recording the discrimination signal. A television receiver characterized in that it sends a discrimination signal that defines the distinction between image reception and non-image reception, and when selecting a mode, transmits the selection signal C output from the port 13 to the mode switching circuit 2 as a control signal. A television receiver according to claim 1, wherein the information processing circuit 1 is a one-chip microcomputer.
