Abstract

A method for selecting a key value of a remote controller is provided to allow a user to interchange two key values when a position change key of a remote controller is inputted to arbitrarily change a key value of a desired position. When a user first selects a position change key and inputs a position change key value(S10), it is checked whether an arbitrary key value 'A' is inputted(S20). When the key value 'A' is inputted, the key value 'A' is stored in a memory unit(S30), and it is checked whether an arbitrary key value 'B' is inputted(S40). When the key value 'B' is inputted, the key value 'B' is stored in the memory unit(S50) and the inputted key values 'A' and 'B' are interchanged so as to be newly set. That is, the key value of 'A' is set as the key value of 'B', and the key value of 'B' is changed to the key value of 'A'(S60).

The present invention relates to a remote control, and more particularly, to a remote control key value setting method for arbitrarily changing the key value of the remote control.

In general, the remote control device is used for the purpose of remote control without using a function key attached to a television or the like. In addition to the basic functions such as volume control, channel switching, and power on / off output from a television, the remote control device can also display time and characters on the screen of a television, using a graphical user interface (GUI) environment. .

Accordingly, various keys have been added to the remote control device to implement such a function. Currently, a remote control device which is commercially available has more keys than in the related art.

On the other hand, even though the function of the remote control device is increased, the numeric keys of the remote control device still occupy a large part of the area where the keys of the remote control device are located, and in the case of the television, it is not used except for channel tuning.

1 is a perspective view showing the key arrangement of a conventional remote control device.

In a typical remote control device, as shown in FIG. 1, a power key is disposed at an upper front side thereof, and a function key 13 including a numeric key 11 and a menu key below it, and a channel key and a volume key 15. In particular, even though the numeric keys 11 occupy a large part of the remote controller 10, when the actual remote controller is not used much and only wants to move to a specific channel, The function of moving to the channel is limited to that performed.

On the other hand, a channel key or a volume key that is actually used by a user is often inconvenient when it is disposed under the remote controller 10 and is actually held by a hand.

That is, when the user uses the remote controller 10, there is a problem that it is not only inconvenient depending on the key arrangement state, but also inefficient.

The present invention has been made to solve the above-mentioned problem, and if the remote control is provided with a position change key separately and the position change key is input, the two key values are subsequently changed to change the key value of the position desired by the user. An object of the present invention is to provide a method for setting a key value of a remote controller, which can be changed arbitrarily.

The present invention devised to achieve the above object is as follows. In the remote control key value setting method of the present invention, in the remote control key value setting method of setting a key value assigned to each key of a remote controller for generating an infrared signal according to the key value stored in the memory unit, the first key input of two key values sequentially input is performed. Storing a key value, changing a later input key value into the first input key value, changing the first input key value into the later input key value, and changing the two key values.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

2 is a block diagram of a remote controller key value changing apparatus according to an embodiment of the present invention, Figure 3 is a flow chart of a remote control key value setting method according to an embodiment of the present invention.

In the remote control key value changing apparatus according to the embodiment of the present invention, as illustrated in FIG. 2, the key input unit 70 for allowing a user to select various control commands, including a numeric key 74 or a function key, and the above-described keys. A memory unit 60 for storing key values for the keys of the input unit 70, a signal output unit 80 for outputting the above-described key values as an infrared signal, and a microcomputer for controlling the remote controller key value changing device of the present invention. 50).

In particular, the key input unit 70 is provided with a separate position change key 72, the position change key 72 to change the key value described later by the microcomputer 50.

As described above, when the position change key is selected from the position change key 72 of the key input unit 70, the microcomputer 50 subsequently changes the key value of each of the two keys input from the key input unit 70. This process will be described in detail with reference to FIG. 3.

In the remote control key value setting method according to the embodiment of the present invention, as shown in FIG. 3, when the first user selects the position change key 72, if the position change key value is input (S10), it is determined whether an arbitrary A key value is input. Determine (S20).

At this time, when the A key value is input, the A key value is stored in the memory unit 60 (S30), and it is judged again whether an arbitrary B value is input (S40).

Also, when the B key value is input, the B key value is stored in the memory unit 60 (S50), and the A key value and the B key value previously inputted are newly set.

That is, the key value for the A key is set to the key value for the B key, and the key value for the B key is changed to the key value for the A key.

Therefore, when the A key value is input, the infrared signal corresponding to the B key value is output to the signal output unit 80. When the B key value is input, the infrared signal corresponding to the A key value is output to the signal output unit 80.

For example, when the user wants to change the channel up key of the channel key to the number 3 key of the numeric key, the user first selects the position change key 72.

Accordingly, the position change key value is input to the microcomputer 50, and the microcomputer 50 changes the subsequently input key value according to the position change key value. When the user first selects the channel up key, the channel up key value is stored in the memory unit. If the user selects the third key afterwards, the third key value is stored in the memory unit 60.

As such, when the channel up key value and the key 3 value are stored, the channel up key value is set to the key 3 value, and the key 3 is set to the channel up key value.

Therefore, when the user inputs the third key value, the microcomputer 50 reads the key value from the memory unit 60 to determine whether the third key value has changed and determines whether there is a changed key value for the third key value. Therefore, when the third key value is input, the channel up key value is transmitted as an infrared signal by reading the channel up key value.

Here, whether or not the channel is changed is output through the menu box or voice of the TV so that the user recognizes that the channel key value has been changed. As such, when the specific function is changed, the outputting thereof through the OSD unit or the buzzer may be easily performed by those skilled in the art, and thus the detailed description thereof will be omitted.

The present invention is not limited to the above-described embodiments and can be carried out in various modifications within the scope of the technical idea of the present invention.

According to the present invention configured as described above, if the remote control is provided with a position change key separately and the position change key is input, the user can arbitrarily change the key value of the desired position by mutually changing two input key values thereafter. .
