Abstract

PURPOSE: To enable the execution of demonstration by AC alone even in the absence of power source on and execution start input. CONSTITUTION: A demonstration memory device processing section 4 is inputted with a demonstration mode stored in a memory device 5 at the time of the AC on. This processing section instructs the power source on and the demonstration execution to an input processing section 2 if the demonstration mode is a content to execute the demonstration.

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a demonstration reproduction circuit.

[0002]

2. Description of the Related Art FIG. 2 is a block diagram showing a conventional demonstration execution system (Japanese Patent Laid-Open No. 4-182726). In FIG. 2, when the execution of the demonstration is requested by the input device 12, the control device 11 reads the demonstration data 15 stored in the external storage device 14 into the internal storage device 13, and executes the demonstration based on the demonstration data 5. To do.

In the conventional demonstration function, the demonstration is not started unless the input device requests the execution of the demonstration. In order to execute the demonstration, the operation input for executing the demonstration was required after the power was turned on from the standby state.

[0004]

However, in the above-mentioned configuration, the demonstration cannot be started unless the power button operation input and the demonstration button operation input are performed after the AC is turned on in the store display.
It had a problem that it was not effective in promoting sales.

An object of the present invention is to enable a demonstration to be executed without a power-on input by a power button and a demonstration execution start input by a demonstration button.

[0006]

In the demonstration reproducing circuit of the present invention, when the AC input section instructs the demonstration processing section to be turned on from AC off when the AC is on, the demonstration storage processing section is stored in the storage device. If the demonstration mode is input and the demonstration mode is to execute the demonstration, the input processing unit is instructed to turn on the power and execute the demonstration.

[0007]

With this configuration, the demonstration can be executed without the operation input of the power button of the input operation section and the subsequent demonstration button.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A demonstration reproduction circuit of a television receiver according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a main part of a demonstration reproduction circuit of the present invention. FIG.
3, 3 is an input operation section having a power button 10 and a demonstration button 9, 5 is a storage device for storing the demonstration mode, 7 is an AC input section for detecting a change in AC input, and 4 is the AC mentioned above. Demonstration mode storage processing unit that determines the contents of the demonstration mode of the storage device 5 by input from the input unit 7, and 2 is an input processing unit that determines the output from the input operation unit 3 and the demonstration mode storage processing unit 4. 1 is a demonstration execution circuit that executes a demonstration by the output from the input processing unit 2, 8 is a power supply circuit that supplies power by the output from the input processing unit 2, and 6 is the power supply circuit 8 Of the demonstration execution circuit 1 by supplying power from It is a screen display circuit to display line content.

The operation of the demonstration reproducing circuit configured as above will be described. Once the demonstration button 9 of the input operation unit 3 is pressed and the demonstration mode storage processing unit 4 writes the content to execute the demonstration in the storage device 5, the subsequent A
Demonstration mode memory processing unit 4 when C is on
However, when the AC ON signal from the AC input unit 7 is input, the demonstration mode is read from the storage device 5, and if the read demonstration mode indicates that the demonstration is being executed, the demonstration mode storage processing unit 4 instructs the input processing unit 2 Power circuit 8
Power-on and instruction to execute the demonstration, the input processing unit 2 causes the demonstration executing circuit 1 to execute the demonstration, and the power supply circuit 8 causes the screen display circuit 6 to operate.
Is displayed, and the contents of the demonstration are displayed on the screen display circuit 6.

[0010]

As described above, according to the present invention, depending on the contents of the demonstration mode of the storage device at the same time as the AC is turned on, even if there is no power-on input by the power button of the input operation unit after AC is turned on or demonstration start input by the demonstration button. The power-on and execution of the demonstration are reproduced, and the demonstration function is effectively used for sales promotion in the store display, and its practical effect is great.
