How to switch the mode of the remote controller

The present invention relates to a mode switching method of a remote controller, and more particularly, to a mode switching method of a remote controller suitable for allowing a plurality of devices that can be controlled by the remote controller to be controlled by one remote controller. It is about.

In this regard, the operation of the remote controller according to the related art is briefly described as follows.

First, when operating a predetermined key (not shown in the figure) mounted on the corresponding remote controller (not shown in the figure) in order to control a desired function of a particular target device, the micom (micom) built in the above-described remote controller is operated. (Not shown in the drawing) encodes according to the above-described key operation to output a predetermined signal for infrared output, and finally, the predetermined output unit (not shown in the drawing) receives a signal from the aforementioned microcomputer. By outputting the infrared rays to the infrared receiver end (not shown in the drawing) of the target device described above, the target device described above decodes the infrared rays applied from the infrared receiver end to execute a predetermined function.

In this case, the above-described output unit outputs infrared rays by emitting a predetermined light emitting diode (LED).

In addition, in order to control another device remotely, another corresponding remote controller is used to perform the above-described operation to remotely control the other device.

However, this conventional technology has a drawback in that each remote controller must be provided to remotely control a plurality of devices each capable of remote control.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described drawbacks, and provides a method for mode switching of a remote controller to control a plurality of devices which can be controlled by a remote controller by switching modes with a single remote controller. have.

In order to achieve the above object, the present invention converts a video cassette recorder (VCR), a television (TV), and an audio device that can be controlled by a remote controller to a single remote controller. It is characterized by a control box.

The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

Hereinafter, an embodiment of the present invention for achieving the above object in detail.

Referring to FIG. 1, FIG. 1 is a block diagram illustrating a hardware embodiment of a remote controller to which a method for switching a mode of the remote controller according to the present invention can be applied. A key input unit 10 for key operation to select a desired function of the device according to the set mode by setting the mode of the device, and the predetermined signal for infrared output by encoding according to the key operation of the key input unit 10 described above And an output unit 30 for outputting the infrared signal according to the signal of the microcomputer 20 to the target device according to the set mode.

The present invention thus made will be described in detail with reference to FIG. 2 as follows.

First, the key input unit 10 selects a desired function of a device according to a set mode by setting a mode of a corresponding device among a V-Cal, a TV, and an audio device which can be controlled by a remote controller according to the present invention by a user operating a key. .

In this case, the device that can be controlled by the above-described remote controller may be set in addition to V-Cal, a TV, and an audio device.

Next, the microcomputer 20 encodes the key operation of the key input unit 10 as described above, and outputs a predetermined signal for infrared output. The output unit 30 generates infrared rays according to the signal of the microcomputer 20 described above. Output to the target device according to the set mode.

At this time, the above-described output unit 30 will emit infrared light by emitting a predetermined light emitting diode.

Figure 2 is a flow chart showing step by step an embodiment of a mode switching method of a remote controller according to the present invention.

First, in an audio / video system including V-Cal, a television, and an audio device that can be controlled by a predetermined remote controller, if the mode key of the remote controller is not selected, the remote controller described above is maintained by maintaining the current mode. To perform the corresponding function according to the current mode (110,120).

Next, when the mode key of the above-described remote controller selects the BC-AL mode, the BC-AL mode is set so that the above-described remote controller operates only in relation to the above-mentioned V-al (130, 140).

Subsequently, when the mode key of the above-mentioned remote controller selects the television mode, the television mode is set so that the above-mentioned remote controller operates only with respect to the above-described television (150, 160).

When the mode key of the remote controller selects the audio mode, the audio mode is set so that the remote controller operates only in relation to the audio device described above (170, 180).

In addition, when the mode key of the remote controller selects the audio / video mode, the audio / video mode is set so that the above-described remote controller operates in relation to the VR, the TV, and the audio device.

In other words, the above-described remote controller operates only in relation to the device according to the selected mode.

At this time, if the mode key of the remote controller selects the audio / video mode in the above-described steps 190 and 200, the remote controller operates for both V-Cal, television, and the audio device. In particular, the television is switched to the line mode. In this mode, it is possible to set various functions such as to perform only a display function and to output audio through an audio device.In such a mode, each device may be selectively turned off to eliminate unwanted functions. will be.

In addition, the key for mode setting may be set according to each mode, or each mode may be set sequentially each time it is pressed by using one key.

As described above, the present invention is advantageous in that the use of the remote controller is more convenient by controlling the modes of the V-Cal, the TV, and the audio device, which can be controlled by the remote controller, by controlling the modes by controlling the remote controller.
