Description

How to Define Input Keys for Your TV

The present invention relates to a method of defining an input key of a television. In particular, the function of a predetermined number of keys attached to the front of a television can be defined according to the frequency of use by the user so that the number of input keys of the television can be reduced. A method for defining input keys.

Recently, the keys for operating home appliances are increasing due to the variety of functions of TVs, and in order to provide convenience to users, remote controllers capable of wirelessly inputting keys are used. .

In addition, a mandatory input key is fixed to the front panel of the television front part in case the remote control is broken or lost, and other input keys are provided on the remote control. However, as the number of input keys increases, the number of input keys to be provided on the front panel increases as the menu-based OSD (On Screen Display) is adopted (for example, power on / off key, channel up / down key, volume). Up / down key, menu key, menu selection up / down key, menu selection key, etc.) also limited the diversity of the design.Front input keys are different for each user, so the functions of the front panel are fixed. There was an inconvenience in using the input keys.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for defining an input key of a television such that the function of an input key provided in the front portion of the television can be reset.

A method for defining an input key of a television according to the present invention is a method for allowing a user to arbitrarily set and use a function of an input key provided in a front portion of a television based on a frequency of use by a user. If a key signal for key definition is applied, displaying a predetermined screen for key definition, storing a function selected by the user corresponding to each input key, and applying the key signal corresponding to a user's input key operation And performing a selected function in response to the received key signal.

On the other hand, the predetermined screen for defining the key is characterized by including all the input key provided and all the functions that can be set correspondingly to be configured so that the user can select by the predetermined key operation.

On the other hand, when displaying a predetermined screen for key definition, it is characterized by displaying and displaying the function currently set corresponding to each input key.

Explanation of symbols for the main parts of the drawings

10: first key input unit 20: second key input unit

21: remote controller 22: receiver

30: microcomputer 40: tuner unit

50: video / audio signal processing unit 60: OSD unit

70: monitor 80: speaker

The above 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, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram of a television employed according to a preferred embodiment of the present invention, wherein the first and second key input units 10 and 20, the microcomputer 30, the tuner unit 40, and the image / audio signal processing unit are shown. 50, an OSD unit 60, a monitor 70, and a speaker 80.

In such a configuration, the first key input section 10 has a predetermined number of keys (for example, a power on / off key and first, second and third input keys whose functions can be set) for performing the operation of the television. And outputs a key signal corresponding to the user's key operation to the microcomputer 30, which will be described later, and is installed on the television front panel.

In addition, the second key input unit 20 includes a user-defined key, a menu up / down key, a menu selection key, etc. for performing the operation of the television, and is caused by a user key operation of the remote controller 21 that can be input from a remote location. The receiver 22 receives, amplifies, and detects the corresponding key signal carried on the predetermined infrared carrier wave transmitted from the remote controller 21 and applies it to the microcomputer 30.

Meanwhile, the microcomputer 30 controls the overall operation of the television by controlling the tuner unit 40, the image / audio signal processing unit 50, and the OSD unit 60, and the user-defined key signal from the second key input unit 20. When is applied, the key definition screen as shown in FIG. 3 is controlled by controlling the OSD unit 60 and each input key (for example, the first input key KEY1) of the first key input unit 10 is controlled. In response to the second input key KEY2 and the third input key KEY3), the corresponding function selected by the user is stored so that the user can define the function of the input key of the first key input unit 10. When a key signal is applied from the first key input unit 10, the control unit performs a selected and stored function corresponding to the applied key signal.

The tuner unit 40 outputs a broadcast signal received by being tuned to a corresponding channel corresponding to the control of the microcomputer 30.

In addition, the video / audio signal processing unit 50 separates the broadcast signal applied from the tuner unit 40 into an image and audio signal under the control of the microcomputer 30, and processes the audio signal into a signal capable of outputting a speaker ( 80), the video signal is processed into a displayable signal and output to the OSD unit 60.

On the other hand, the OSD unit 60 reads out the text signal corresponding to the control of the microcomputer 30 and synthesizes the video signal from the video / audio signal processing unit 50 or the blue-back video signal to monitor 70. To control the output.

Next, the process of defining an input key of a television according to a preferred embodiment of the present invention including the above-described configuration unit will be described in detail with reference to the flowchart of FIG.

First, the user defines the function of each input key (first input key, second input key, and third input key in the preferred embodiment of the present invention) of the first key input unit 10 provided in the front panel of the television. In order to operate the user-defined key provided in the remote control 21 of the second key input unit 10.

Therefore, the microcomputer 30 determines whether the user defined key signal is applied through the receiving unit 22 of the second key input unit 10 (step 200), and when the user defined key signal is applied, as shown in FIG. The key definition screen as described above is controlled and displayed on the OSD unit 60 (step 202).

At this time, the key definition screen is a mode function (for example, channel up, channel down, volume up, volume down, menu, etc.) that can be set corresponding to each input key (for example, KEY1, KEY2, KEY3). Menu up, menu down, menu selection, TV / AV mode, voice mode, etc.) are displayed, and a predetermined key (for example, menu up / down) provided by the user on the remote controller 21 of the second key input unit 20. Key) to move the cursor (Box in the figure) to a desired function, and then a function corresponding to each input key can be selected using a predetermined key (for example, a menu selection key).

Next, as described above, when a function corresponding to each input key is selected and defined based on a user's predetermined key operation, the microcomputer 30 omits the function set corresponding to each input key of the first key input unit 10. Stored in the internal memory (step 204).

Next, when a predetermined input key signal is applied from the first key input section 10, the microcomputer 30 performs the functions defined in step 204 described above in response to the applied key signals by controlling each component of the television. (Step 206).

As shown in FIG. 3, the cursor is displayed at the position of the function currently set corresponding to each input key when the key definition screen is displayed so that the user can know the function currently set corresponding to each input key. .

On the other hand, it will be understood by those skilled in the art that various changes and modifications can be made without departing from the spirit of the present invention.

As described above, according to the present invention, the user can arbitrarily define a predetermined number of input key functions provided on the front part of the television, so that the number of front part input keys can be reduced, and the front part input keys The design can be easily changed without limiting the number of appearances, and there are various possible designs.
