And electrically placing the buttons in a predetermined position according to the key matrix specification.

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

As shown in FIG. 1, an integrated remote controller of a plurality of devices according to the present invention includes a controller 101, a memory 102, a key input unit 103, and a transmitter 104.

In the present invention, a display device and a set-top box are described as a plurality of devices for convenience of description. It is a matter of course that the plurality of devices to which the present invention is applied are not limited to the display device and the set-top box.

The memory 102 stores classified key button codes that are commonly recognizable according to usage patterns of a plurality of devices and key button codes that can be independently recognized for each device.

As an example, in the case of a display device without a tuner and an integrated remote controller of a set-top box that performs overall signal processing for broadcast channel reception and sound output, the code and device of the commonly recognized key button are independent as follows. Can classify the recognized key button codes.

First, the usage patterns of the display device and the set-top box can be classified as follows.

If the display device is not a tuner built-in TV, it must be connected to a set-top box in order to watch broadcasts through the display device. The function is adjusted via a three-top box.

In other words, the set-top box powers on / off the set-top box itself, functions for channel setting (channel +/-, automatic channel memory, channel addition / deletion, etc.), and functions for sound adjustment (volume +/-, mute). (Mute), sound mode, user mode, etc.) and the overall function as a master device.

Here, the power on / off is a function commonly used in the display device and the three-top box, and it is efficient to turn on or off the power of the display device and the three-top box on the usage pattern.

Therefore, a power on / off key button code is assigned to a commonly recognizable key button code.

In addition, the key button codes for setting a function for picture adjustment allocate key button codes that can only be recognized by the display device.

Next, the key button codes for setting the function for the channel setting and the functions for the sound adjustment are assigned key button codes that can only be recognized by the set-top box.

The key input unit 103 electrically arranges a key button that can be recognized in common without a key button for selecting a display device and a set-top box, and key buttons that can be independently recognized for each device according to the key matrix specification. It performs the role of transmitting the electrical information corresponding to the key button input at the time of input to the control unit 101.

The controller 101 recognizes electrical information input according to a user key button input from the key input unit 103, and reads out a key button code corresponding to the input key button from the memory 102.

Then, the transmitter 104 converts the key button code read out from the controller 104 into an electrical signal and transmits the signal wirelessly. As an example, an infrared diode may be used to wirelessly transmit an electrical signal corresponding to the key button code.

Accordingly, when the key button input by the user corresponds to a key button which can be commonly recognized by the display device and the set-top box, the integrated remote controller according to the present invention provides a key button code that the display device and the set-top box can recognize together. Create

Of course, if a key button that can be independently recognized for each device is input, if the input key button is a key button related to setting a function for picture adjustment, a key button code that only a display device can recognize is generated. In the case of a key button related to a function of channel setting and a function of sound adjustment, a key button code that only the top box can recognize is generated.

That is, as shown in FIG. 2, when a power on / off key button B1 which is commonly recognized among key buttons of the integrated remote controller 201 of the multiple devices according to the present invention is input, a display device (apparatus A; 202) and a button button K1 that can be recognized together at the set-top box (device B; 203), and a button (e.g., brightness adjustment button; B3) related to setting a function for picture adjustment; In this case, a key button code K3 that can only be recognized by the display device 202 is generated, and a button (e.g., channel +; B2) related to a function for channel setting and sound adjustment is input. Generates a key button code K2 that can only recognize the set-top box 203.

Next, a method for designing an integrated remote controller of a plurality of devices according to the present invention will be described with reference to the flowchart of FIG. 3.

First, after analyzing the usage pattern for the functions of the multiple devices controlled by the integrated remote controller, the key buttons related to the commonly available functions are classified (step 301).

Next, key buttons regarding functions to be individually recognized for each device are classified (step 302).

Then, assign a key code that can be recognized by a plurality of devices together for key buttons related to commonly available functions, and key devices for functions that must be individually recognized for each device. A key code that can only be recognized is assigned (step 303).

Next, the key button codes related to the assigned commonly available functions and the key button code values to be individually recognized for each device are stored in the memory (step 304).

The controller 101 reads the key button code values corresponding to the key buttons input from the memory 102 according to the key buttons selected by the user through the key input unit 103. Control to transmit via communication.
