Abstract

A method for displaying the input state of a remote controller is provided to enable a user to manipulate a remote controller conveniently at a dark place or in a situation difficult to confirm key buttons exactly by displaying the input state of a pushed key button on the screen so that the user can exactly recognize which key button has been inputted. If a signal is received from a remote controller when an input state display mode is in an active state(S10), a microcomputer judges how long the signal is continuously received(S12). In other words, the microcomputer judges whether an arbitrary key button corresponding to the received signal has been continuously pushed during more than the first setting time. If so, the microcomputer executes an operation corresponding to the received signal(S14). However, if it is judged that the arbitrary key button has been pushed shortly during less than the first setting time, the microcomputer displays the key input part of the remote controller and the arbitrary key button so that the user can exactly recognize which key button has been inputted(S16).

The present invention relates to a method for displaying an input state of a remote controller to be recognized when a corresponding key button is continuously input.

In recent years, it is difficult to provide all of these keys on the front of the main body of the home appliance because of the increasing number of keys for using the functions due to the variety of home appliance functions. In order to eliminate the inconvenience of having to operate in close proximity to the equipment, a remote controller (Remote Controller: commonly referred to as a Remocon) that allows key input wirelessly from a remote place is widely used.

1 is a block diagram schematically illustrating a general television.

As shown here, an antenna 10 for receiving a composite video signal of various channels transmitted from a broadcasting station, a tuner unit 20 for processing channel selection, high frequency amplification, etc. of the television signal received from the antenna 10; And an image intermediate frequency detector 30 for detecting and amplifying the image intermediate frequency from the image signal processed by the tuner 20, a main IC 40 for performing Y / C separation and chromaticity processing, and a CRT. A video output unit 50 for displaying a television signal at 60, a microcomputer 70 for controlling the television system, and a memory unit 80 connected to the microcomputer 70 to store various data information. And an OSD processing unit 90 for displaying an OSD on the CRT 60 under the control of the microcomputer 70, and a remote control receiving unit 100 receiving a command signal from the remote controller 110 and applying the command signal to the microcomputer 70. It consists of.

Therefore, when the key is input from the remote controller 110, the infrared carrier is amplitude-modulated based on the key code corresponding to the pressed key and transmitted through the infrared light emitting element. 70) As the TV is operated by analyzing the key code, it is possible to easily control the screen color, select the channel or set the current time while watching the OSD (On Screen Display) screen of the television remotely. .

As described above, the convenience of easily operating a television using a remote controller is provided, but the remote controller is not only made relatively small but also formed of small buttons to add many functions.

Therefore, when trying to operate the remote control in the dark, not only is it inconvenient to find the corresponding key button, but the elderly have poor visual acuity.

The present invention was created to solve the above problems, an object of the present invention is to greatly increase the input state of the key button on the screen to check whether the corresponding key button is correctly input when any key button on the remote control; The present invention provides a method for displaying an input state of a remote controller to be recognized when a corresponding key button is continuously input after being displayed.

The present invention for achieving the above object is a first step of receiving a signal transmitted from the remote control, a second step of determining the duration of the received signal, and if the duration is more than the first set time to the received signal And a fourth step of performing a corresponding operation, and a fourth step of displaying a key button of a remote controller and displaying a key button corresponding to a received signal when the duration is less than the first set time. do.

The present invention is characterized in that the input state display mode of the remote control on and off.

The present invention is characterized in that to delete the key button displayed on the screen when performing the operation corresponding to the signal received in the third step.

The present invention is characterized in that the key button displayed on the screen is deleted if there is no new signal received during the second set time after the corresponding key button is displayed in the fourth step.

According to the present invention, when any key button of the remote controller is pressed for less than the first setting time, the key button pressed while the key input unit of the remote controller is displayed on the screen can determine which key button the user pressed. After confirming the key button pressed correctly, if the corresponding key button is pressed continuously, it is recognized so that accurate remote control operation can be made.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings, and the same parts as in the prior art use the same reference numerals and names. In addition, the present embodiment is not intended to limit the scope of the present invention, but is presented by way of example only and those skilled in the art will be capable of many modifications within the technical spirit of the present invention.

2 is a flowchart illustrating an input state display method of a remote controller according to an exemplary embodiment of the present invention.

First, as shown in the present invention, the input state display mode can be set on and off in order to display the input state of the remote control on the screen of the television. The operation corresponding to the key button is performed.

In the present embodiment, the signal transmitted from the remote controller is received while the input state display mode is turned on (S10).

Then, it is determined how continuously the received signal is received (S12).

That is, it is determined whether any key button of the remote controller is continuously pressed for about 2 seconds or more in the first setting time. In this case, 2 seconds is a value set arbitrarily and is a value used in the present embodiment to determine a duration, and may be set to a different value according to a situation.

It is judged that the key button is continuously pressed to confirm and recognize the key button.

Thus, when continuously received for more than the first predetermined time as described above, an operation corresponding to the received signal is performed (S14).

If the key input unit and key button of the remote control is displayed on the screen, the displayed screen is deleted (S20).

However, when a signal is received for a short time of less than 2 seconds, the key input unit and a key button corresponding to the received signal are displayed to check which key button is pressed.

That is, as shown in FIG. 3, the key input unit of the remote controller is displayed on the screen, and if the volume up button is pressed, the pressed key buttons are displayed differently as shown on the screen, so that the key buttons input by the user can be accurately identified. Make sure

If the key button is pressed continuously for 2 seconds or more, the corresponding key button is performed.

If another key button is pressed for a short time of 2 seconds, the other key button is displayed as being pressed (S16).

In this way, the key button of the remote controller is pressed on the screen to accurately find the key button to be pressed.

When no remote control signal is received for about 5 seconds during the second set time while the key input unit and the key button of the remote control are displayed on the screen, the key input unit and the key button displayed on the screen are deleted (S18) (S20). .

In this case, 5 seconds of the second setting time may be arbitrarily set to another value as the value set in the present embodiment.

In this way, if any key button on the remote control is input, the input key button is displayed on the screen so that it is difficult to check the key button accurately in the dark or poor eyesight. So that the remote control can be operated conveniently.

As described above, the present invention recognizes when the key button is continuously input after displaying a large input state of the key button on the screen so that the key button is correctly inputted when an arbitrary key button is input on the remote controller. When it is difficult to check the key button accurately in a dark place or poor eyesight, there is an advantage that the remote control can be conveniently operated by confirming by continuously pressing the key button to be pressed.
