EDID (Extended Display Identification Data) 400 represents a kind of data structure as extended display identification data, and includes various information about a monitor in particular. For example, if the monitor information of the computer is transmitted to the graphics card, the computer can find out which monitor is connected through the information included in the EDID. EDID has been defined as a standard by VESA (Video Electronics Standards Association). Referring to the EDID data structure 400 shown in FIG. 4, product manufacturer name, product type, EDID version, phosphor or filter type, timing, screen size, It can be seen that information about luminance, pixels, etc. is included. Among these various EDID data structures (400), the 'ID Manufacture Name' (410) field value is a value that identifies the manufacturer name, and the 'ID Product Code' (420) field value is a value representing the unique code value information of the product am. In addition, the 18-byte 'Display Descriptor' field includes a 'Display Product Name' (430) field value, which corresponds to a field value for distinguishing the product name.

Therefore, 'ID Manufacture Name' (410) field, 'ID Product Code' (420) field, and 'Display Product Name' (430) field values are extracted from the EDID (400) information, and based on them, a display device connected through HDMI The 'manufacturer and product model' information 440 of 300 can be grasped, and based on the 'manufacturer and product model' information 440, corresponding unique IR codeset information 450 is detected to display the device 300. ) can be used as an IR remote control command code.

Among the EDID information received through HDMI, the 'Manufacturer Id (PnPID)' field value corresponding to the manufacturer ID can be extracted from the Standard Data (500S) to confirm the 'GSM' value corresponding to the manufacturer ID. Also, '0x59DA' corresponding to the product ID can be checked by extracting the 'Product ID' field value. In addition, among the EDID information, Detailed Data (500D) can extract values such as Product Timing Block (Block 1), Display Range Limits (Block 2), Display Product Name (Block 3), and Display Product Serial Number (Block 4). In addition, the product name can be confirmed by extracting the '23EN43' value, which is the 'Display Product Name' field value of Block 3.

Based on the three field values 'GSM', '0x59DA', and '23EN43' extracted in this way, the TV manufacturer and TV product name can be accurately identified.

In this embodiment, the TV 300 is exemplified for convenience of description of the display device, but the display device is not necessarily limited to the TV.

As shown, the remote control device 100 and the setting device 200 are connected through a first interface, and the TV 300 and the setting device 200 are connected through a High Definition Multimedia Interface (HDMI).

First, when the setting device 200 and the TV are connected through HDMI (S601), the setting device 200 receives EDID information of the TV 300 through HDMI (S603).

Manufacture ID, Product ID, and Display Product Name field values are extracted from the EDID information received through step S603 (S605). The details of step S605 have been previously described with reference to FIGS. 4 and 5, and a detailed description thereof will be omitted.

Based on the EDID information extracted through step S605, the manufacturer and model of the TV 300 connected through HDMI are determined (S607), and based on this, an IR code set for IR control of the TV 300 is extracted from the IR database Do (S609).

That is, when the manufacturer and model information of the TV 300 confirmed through step S607 is transmitted from the setting device 200 to the cloud server 400 (S611), the cloud server 400 matches the manufacturer and product model. An IR code set is extracted (S613). Thereafter, the extracted IR codeset is transmitted from the cloud server 400 to the setting device 200 or downloaded from the setting device 200 (S615).

Through the modified embodiment (S610) as described above, there is an advantage in that IR code sets of various products can be searched for and downloaded in real time, and information on the latest updated version of the code set can be provided as needed. .

Meanwhile, the IR code set extracted through step S609 or step S615 is transmitted from the setting device 200 to the remote control device 100 through the first interface (S621).

The remote control device 100 sets the received IR code set as a TV control code and transmits an Ack signal for this to the setting device 200 (S623).

Thereafter, the remote control device 100 performs test steps (S631 to S639) for IR control.

That is, the remote control device 100 extracts the TV 300 Power Off signal from the IR code set and transmits it to the IR (S631).

When the TV operates in the OFF mode in response to the Power Off control in step S631 (S632), the setting device 200 can check the Off Event of the TV through HDMI (S633). If the Off mode operation of the TV 300 is confirmed, the setting device 200 transmits a TV Off confirmation signal to the remote control device 100 (S634).

Thereafter, the remote control device 100 extracts the TV 300 Power ON signal from the IR code set and transmits it to the IR (S635).

When the TV operates in the ON mode in response to the Power ON control in step S635 (S636), the setting device 200 can check the ON Event of the TV through HDMI (S637). If the ON mode operation of the TV 300 is confirmed, the setting device 200 requests the TV to output a setting completion screen through HDMI (S638).

In response to the setting completion screen output request (S638), the TV 300 outputs the setting completion screen (S640).

In addition, when the ON mode operation of the TV 300 is confirmed through step S637, the setting device 200 transmits a TV ON confirmation signal to the remote control device 100 through the first interface (S639).

Upon receiving the TV ON confirmation signal from the setting device, the remote control device 100 informs the user through means such as vibration, voice guidance, and display so that the user can confirm that the setting for IR control of the TV 300 has been successfully completed (S641 ). For example, when the remote control device 100 is a remote control, it is possible to notify the user of the completion of setting through a method of blinking an LED a predetermined number of times.

Then, the remote control device 100 can directly control the TV 300 through IR transmission using the set IR code.

In this embodiment, the IR code set is not extracted from the setting device 200 or the cloud server 400, but extracted from the DB inside the remote control device 100.

Manufacture ID, Product ID, and Display Product Name field values are extracted from the EDID information received through step S603 (S605). Details of step S605 have been previously described with reference to FIGS. 4 and 5, and a detailed description thereof will be omitted.

Based on the EDID information extracted through step S605, the manufacturer and model of the TV 300 connected through HDMI are determined (S607).

The TV manufacturer and model information determined through the step S607 is transmitted to the remote control device 100 through the first interface (S721).

Through step S721, the remote control device 100 checks the manufacturer and model of the TV 300 to be controlled, and extracts a matched IR code set from the IR database stored in its storage unit (S723).

The extracted IR code set is set as a TV control code and an Ack signal for this is transmitted to the setting device 200 (S725).
