Description

How to Control Key Codes on the Remote Controller

The present invention relates to a method of controlling a key code of a remote controller, and more particularly, to a method of controlling a key code of a remote controller suitable for operating a key of a general remote controller as a key for a factory check.

In this regard, in the case of mass production at a factory of a remote controller according to the prior art, if a key related to a matter to be checked must be placed and managed, there is a difficulty in setting a corresponding code as the check content increases. If you need to operate using), etc., there is an inconvenience of plugging and unplugging the diode.

The present invention has been made to solve the above-mentioned drawbacks of the prior art, and the key code control method of the remote controller that allows the remote control key to operate as a factory check key in the factory check mode by setting a separate key code for the factory check. The purpose is to provide.

In order to achieve the above object, the present invention designates one key code that is not used by the consumer among the key codes of the remote controller, and when the key is selected, switches to the factory check key mode and when the designated key is selected again. It is designed to operate in the factory check key mode.

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 Figure 1, Figure 1 is a block diagram for applying a key code control method of a remote controller according to the present invention, a remote controller 10 for remotely controlling the set, and the above-described remote controller 10 And a television 30 which is controlled by the remote controller 10 connected to the above-mentioned VLC 20 and controlled by the above-described remote controller 10 to execute the function. .

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

First, the user can remotely control the V-Cell 20 and the TV 30 by manipulating a predetermined key of the remote-controller 10 so that the V-Cal 20 is controlled by the remote controller 10 described above. To play or record.

Next, the television 30 is connected to the above-mentioned VRT 20 and controlled by the above-described remote controller 10 to have an audio / video output from the VRC 20 or its own audio / video output. It outputs through (speaker) and screen so that users can watch it.

In this case, briefly describe the principle of the VCS (Video Cassette Recorder) as follows.

We can easily call it VSI, but it was originally called Video Cassette Recorder, which is the correct name. In Korean, it can be called 'self-recording playback'.

It is a device that records video signals from the outside and records them on tape through the head of VRC.

Here, the head is a kind of electromagnet, which causes a change in the magnetic force according to the electric change, and is recorded by contacting the tape emitting head with the magnetic signal.

At this time, the tape is iron powder coated on the vinyl, the iron powder is magnetized according to the change of the magnetic force of the head.

You can also select the recording speed of VRF.

The recording speed can be divided into standard speed (SP mode) and triple speed (SLP mode or EP mode: 6 hours of use for 2 hours tape).

If you don't have important recordings, you can record at three times the speed, but the video quality is lower than standard speed recording.

In addition, there are two types of home VRs, β type and VHS (Video Home System) type. The basic concept of the two types is the same, and the tape used is 1/2 inch wide.

The principle of the television (TeleVision) is briefly described as follows.

First, a video signal of a television is divided into a color signal, a contrast signal, and a synchronization signal. When the contrast signal and the color signal are mixed and converted, an image is formed in the CRT.

On the other hand, the synchronization signal is a signal of an image transmitted from a broadcasting station, which represents one picture as 525 lines, and may be said to be a conversion device necessary to prevent each of these lines from being disturbed on the CRT.

In other words, it is the television screen we are watching that is transmitted through lines and shown as a picture.

The station sends 30 pictures per second to the receiver, and the number of lines (scanning lines) that make up one picture per second is drawn as 525 strands X 30 scenes = 15,750 strands.

Because of this, the contrast of the same place changes every 1/30 seconds, so the movement can be fully expressed.

In short, the basic principle of television is hidden in transmission and reception. The first process is to divide a single image into pixels of the minimum unit, photoelectrically convert one by one in a certain order, and then send them one by one.

The receiving side then converts light from electricity in the reverse order, resulting in the original image.

This process is called scanning, and the scanning is repeated one horizontal scan from the upper left to the lower right of the screen.

This is the process by which the program produced by the broadcasting station can be seen in the same place in the viewer's desired place.

2 is a flowchart illustrating a step-by-step embodiment of a method of controlling a key code of a remote controller according to the present invention, and is an algorithm of a predetermined micom mounted in the remote controller 10 described above.

First, designate the key code not used by the consumer among the key codes of the remote controller as the factory check key code, and if the key code is selected, the remote controller is in the factory check key mode if the current remote controller is not in the factory check key mode. Switch to (110, 120, 130, 180).

Next, in the above-described step (110, 120, 130, 180) in the current factory check key mode is switched to the key operation mode of the general remote controller (140).

Subsequently, when the factory check key code is not selected in the above-described steps 110, 120, 130, and 180, if the current factory check key mode is selected, the key input of the remote controller is operated as the corresponding factory check key (150, 160).

In operation 150 and 160, if the key mode for the factory check is not present, the key operation mode of the general remote controller is maintained (170).

As described above, according to the present invention, the factory check key code is set aside so that the general remote control key operates as the factory check key in the factory check mode, so that the factory check can be performed very easily.

Claims (1)

The first step of designating a specific key code among the key codes of the remote controller as the factory check key code and when the key code is selected, converting the remote controller to the factory check key mode when the current remote controller is not in the factory check key mode. (110,120,130,180); A second step (140) of switching to a key operation mode of a general remote controller when the first step (110, 120, 130, 180) is performed and the current factory check key mode is performed in the first step (110, 120, 130, 180); After performing the first step (110,120,130,180), if the factory check key code is not selected in the first step (110,120,130,180), the third step of operating the key input of the remote controller with the corresponding factory check key if the current factory check key mode (150,160); After performing the third step (150,160), the third step (150,160) of the remote controller is performed by sequentially performing the fourth step 170 to maintain the key operation mode of the general remote controller, if not the key mode for the current factory check How to control key code.
