A remote control device 1 having a function selection key 130, input signal determination means 2 for determining an input signal by the remote control device 1, arithmetic operation means 5 for executing a calculation process, and the input Control means for controlling the entire apparatus in accordance with the determination signal by the signal determination means ( 3), OSD pattern data in accordance with the data memory 4 for storing the processing data by the control means 3 and the calculation result value by the arithmetic operation means 5, the control signal by the control means (3) And generating OSD generating means (7), wherein said control means (3) stores the data input from said remote control device (1) and stored in said data memory (4) when said function selection key (130) is pressed once. The data is output only when the calculation result values match, and when the function selection key 130 is pressed twice, the calculation result value stored in the data memory 4 is output as it is.

2 is a diagram showing an example of the arrangement of keys of the remote control device for selecting the calculation function or the number play function in the configuration of FIG. 1, and the remote control device 1 according to the present invention uses a plurality of numeric keys 110 as in the usual manner. In addition to the addition, the operation key 120 and the function selection key 130 for arithmetic operation are provided.

In the configuration of FIG. 1, when the viewer presses the function selection key 130 of the remote control device 1 once, the viewer functions as a calculator, and when the function selection key 130 is pressed twice, the number play function is performed. have.

Hereinafter, the operation of FIG. 1 will be described with reference to the flowchart shown in FIG.

When the viewer presses the function selection key 130 using the remote control device 1, the controller 3 outputs a control signal from the output port P1 to the matrix circuit 12, and the OSD generator 7 ) To output the OSD control signal to form, for example, a blue back screen on the CRT (ST2 step).

In addition, the control unit 3 outputs a switching signal to the switching unit 13 so that the sound signal from the sound generating unit 6 is output to the voice amplifier 14 (step ST3).

Then, the calculation function is performed until the function selection key 130 is pressed again (steps ST4 and ST5).

On the other hand, when the function selection key 130 is pressed in step ST4, the number play function is performed (step S6T), and when the function selection key 130 is pressed again while performing the number play function (ST7) Step) Return to normal operation (ST8 step).

That is, the controller 3 performs a calculation function when the viewer presses the function selection key 130 once, performs a number play function when pressed twice, and returns to the initial normal operation state when pressed three times.

FIG. 4 is a flow chart showing the process flow of step ST5 in FIG. 3, that is, the control unit 3 performs a calculation function. The control unit 3 inputs until the = key provided in the remote control unit 1 is pressed. The key data is stored in the data memory 4 and displayed on the CRT screen through the OSD generator 7 (steps ST51 to ST53).

When the viewer presses the = key, the viewer transmits the data stored in the data memory 4 to the arithmetic operation unit 5, and the result value input from the arithmetic operation unit 5 is used as the OSD generator ( 7) is displayed on the CRT screen.

Therefore, the viewer can perform the calculation with the remote control device 1 while watching the CRT screen.

FIG. 5 is a flow chart showing the process flow of step ST6 in FIG. 3, that is, the control unit 3 performs the number play function. The viewer uses the remote control device 1 to display the numeric key 110 or the arithmetic operation key ( When 120 is pressed (step ST61), the control unit 3 stores the input key data in the data memory 4 and displays it on the CRT screen through the OSD generator 7 until the = key is pressed. (ST62, ST63 steps).

Subsequently, when the = key is pressed (step ST63), the control unit 3 sends the data stored in the data memory 4 to the arithmetic operation unit 5 (step ST64), and the result value input from the arithmetic operation unit 5. Is stored in the data memory 4 (ST65 step).

In addition, the controller 3 controls the OSD generator 7 and the sound generator 6 to request a correct answer (step ST66). Flashing or voice. In other words,

2 + 3 =

Next, the controller 3 determines whether the answer is correct based on the key signal input by the viewer and the correct answer data stored in the data memory 4 (steps ST67 and ST68). When the viewer inputs an incorrect answer, the controller 3 re-enters the correct answer. Outputting the OSD data and sound signal requesting (ST69 step), the process proceeds to step ST67 again, and when the viewer inputs the correct answer, the sound generating unit 6 is controlled to output the encouragement sound (step ST70). ).

Therefore, according to the above embodiment, the calculation function and the number play function using the television receiver can be realized.

In addition, this invention is not limited to the said Example, It can variously deform and implement within the range which does not deviate from the technical summary of this invention.
