How to adjust channel by double click

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of adjusting a channel of a television, and more particularly, to perform an up / down operation of a television channel only when the channel up / down key attached to the remote control device is double clicked within a predetermined time. The present invention relates to a channel adjustment method by double-clicking to prevent children from playing up or down a channel by mistake.

Normally, televisions are equipped with simple function keys such as power on / off, channel up / down, and volume up / down in the main body, and most of the function adjustment is performed by using a remote control device. Although these remote controls are convenient to use, they are located close to the body after use, so you may accidentally touch the remote control's function keys or adjust other function keys, and then accidentally touch the channel up / down keys. It often happens up and down.

These mistakes hinder the viewing of pleasant television. In addition, children can play with the remote control and up / down the channel, interrupting the viewing of programs they want to watch. However, in the related art, since there is no means for preventing such inconvenience, the remote control device has to be placed out of reach of children and then removed again or lost when not in use.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to play an up / down operation of a TV channel only when a user double-clicks a channel up / down key attached to a remote control device within a predetermined time. In addition, the present invention provides a channel adjustment method by double-click that can prevent the channel from being up and down by mistake during use.

Hereinafter, referring to the accompanying drawings, a channel adjustment method by double clicking of the present invention will be described in detail.

According to the method of the present invention, the channel up / down of the TV is actually performed only when the channel up / down function key of the remote controller is double-clicked to prevent the channel up / down due to mischief or mistake of a child, thereby providing a comfortable viewing environment. to provide.

First, the configuration and operation state of a conventional television and a remote control apparatus will be described with reference to an external perspective view of FIG. 1 and a block diagram of FIG. 2.

1 is an external perspective view showing the structure of a general television 20 and a remote controller 7. Usually, the main body of a large television 20 is fixed in one place, and the remote control device 7 for remotely controlling the television 20 has a form that is easy to carry and operate and is compactly configured to be carried by a viewer.

The remote control device 7 is provided with a number of function keys (which differ from one another depending on the television) such as power on / off, channel up / down, volume up / down, etc., and essentially channel up / down keys 71a, 71b. ) Is installed on the surface. The viewer presses the channel up key 71a and the channel down key 71b to change the channel up or down.

However, if the channel is changed once by pressing the channel up / down key as described above, there was an inconvenience in that the channel is frequently up / down due to mischief or misoperation of children while watching.

2 is a block diagram showing an example of an internal configuration of a general TV receiver, and the operating states of the television and the remote control apparatus are as follows.

The broadcast signal of the airwave is received by the antenna 1, and the broadcast signal received by the tuner 2 controlled by the microcomputer 9 is tuned. The IF amplifier 3 amplifies an intermediate frequency (IF) signal output from the tuner 2, and the P / S separation unit 4 includes a surface acoustic wave filter to convert the intermediate frequency (IF) into an image intermediate frequency ( PIF) and voice intermediate frequency (SIF).

The voice detector 5 detects a voice signal from the voice intermediate frequency (SIF), and the voice processor 10 detects the detected voice signal based on the control signal of the microcomputer 9 (Base) and Treble. Voice processing such as volume, volume, etc. is performed, and the processed voice signal is amplified by the voice amplifier 11 and output to the speaker 12. Processing of the bass, treble, volume, and the like is performed by the microcomputer 9 in accordance with a control signal input from the remote controller 7.

The image intermediate frequency (PIF) is detected by the image signal in the image detector 6, the control of the microcomputer 9 by the signal from the remote control device 7 also the detected image signal in the image processor 14 Color, tint, brightness, etc. are processed according to the signal to output R (Red), G (Green), B (Blue) and luminance (Y) signals corresponding to the image signal, and the R, G, B and luminance The (Y) signal is mixed with the R ', G', B 'and OSD blanking signals Y' generated from the OSD generator 13 in the mixer 15 and outputted by the CRT driver 16 through the CRT driver 16. 17), an image is displayed together with the predetermined OSD pattern data from the OSD generator 13.

In addition, the remote control device 7 is a device for the viewer to control the output volume, channel switching, etc., or to remotely control the overall device, and transmits an infrared signal and receives it from the receiving unit 8 of the television to convert it into an electrical code signal. By converting and outputting to the microcomputer 9, the overall apparatus is controlled by the microcomputer 9 in accordance with the electrical code signal.

The method of the present invention performed in the conventional television as described above comprises the steps of: detecting whether a control command for performing a function is input from a remote control apparatus; and determining whether a channel up or down command is detected when an input of the control command is detected. And performing an operation according to the input control command if not a channel up or down command, and detecting whether there is an identical key input within a predetermined time when the channel up or down key is read. When an input is sensed, the method includes determining an up or down operation to be performed according to a channel up or down signal, and adjusting a channel by outputting a control signal according to the determined operation. This will be described with reference to the flowchart of FIG. 3.

The first step in the method of the present invention is to detect at the microcomputer 9 of the television whether a control command for performing a specific function has been input by a viewer from a remote control device 7 located at a remote location. The microcomputer 9 receives a viewer's command through an infrared signal input to the receiver 8.

The infrared signal transmitted from the remote control device 7 to the receiver 8 is modulated into an electrical signal here and then output to the microcomputer 9 after being output. If the function key input is not detected, the microcomputer 9 enters the standby state while maintaining the current operating state. When the viewer command signal generated by pressing the function key from the receiver 8 is input, the microcomputer 9 detects that there is a function key input (100).

The microcomputer 9 determines whether the control command is a channel up / down command when a function key input is detected. That is, according to the present invention, since only the channel adjustment by the channel up or down command is applied, it is checked whether a command other than the channel up / down command is input (200).

If it is determined that the channel up or down command is not input and it is determined that another function key has been input, the microcomputer 9 has a normal control command, that is, when the function key is clicked once. Immediately perform the command indicated by the function key (300). The determination of the function key input can be achieved by storing the electrical signal corresponding to the channel up or down key input in advance in the microcomputer 9 and comparing it when the key function key input is generated.

If it is determined that the function key input is one of the channel up or down key commands, the microcomputer 9 waits and confirms the next key input for a predetermined time t without executing the key input command immediately (400). This is to determine if the viewer is willing to actually up or down the channel.

That is, since the viewer recognizes that the user should double-click to up / down the channel, the viewer intentionally presses the channel up or down key previously pressed within a predetermined time, and the microcomputer 9 is pressed first. Waiting for the key input.

However, if there is no input of the same key (the channel up key is pressed first and the channel up key should be pressed again) for a predetermined time t, the microcomputer 9 determines that the viewer is not willing to change the channel. It is judged as a mischief or mistake of the viewer and maintains the standby state without performing any action. The predetermined time t can be arbitrarily determined at design time, and is preferably, for example, 5 seconds or less and about 1 to 2 seconds.

If the same function key is repeatedly pressed within a predetermined time t after the channel up or down key is pressed, the microcomputer 9 determines that the viewer is willing to change the channel, and the function key inputted by double-clicking The function key for the operation, i.e., the channel up function key or the down function key is identified (500). This is to confirm the correct function of the channel up or down key.

It will be apparent to those skilled in the art to which the present invention pertains that the function check of the channel up or down key can also be performed in step 200 above. In this case, the channel up or down state is configured such that the state is stored in the memory element of the microcomputer 9.

When the input function key is confirmed as described above, the microcomputer 9 outputs a control signal to up or down the channel 600. That is, the microcomputer 9 outputs the international language signal to the tuner 2 used to adjust the channel to tune the channel desired by the viewer. The broadcast signal for the tuned channel as described above is output through the speaker 12 and the CRT 17 after passing through the above-described processing (voice and video processing), so that the viewer can watch the desired broadcast. will be.

In the above description, double-clicking only on up / down of channels has been described, but it is possible to configure in other ways. In other words, the remote control device 7 is provided with a separate function key for activating the double-click function, and in the case of mischief of young children, by operating the double-click function, not only channel up / down but also other functions such as contrast adjustment You can also extend the functions such as volume control.

As described above, according to the present invention, when the channel up / down key attached to the remote control device is double-clicked within a predetermined time, the TV channel up / down operation is performed so as to up / down the channel by children's mischief or mistake during use. There is an advantage that can be prevented.

While the embodiments of the present invention have been described in detail with reference to the accompanying drawings, the present invention is not limited thereto, and the present invention may be variously modified and changed without departing from the spirit or the field of the present invention. It will be readily apparent to those of ordinary skill in the art.
