The authentication processing unit 210 performs an authentication procedure in which the remote controller 100 requesting access to the controlled device 200 is authorized to control the function of the controlled device 200. [ For example, the authentication processing unit 210 determines whether or not the access code provided by the remote controller 100 together with the connection request is an approved access code, and transmits, to the remote controller 100 of the approved access code, It is possible to grant the right to control the function of the access controller 200 and to perform the authentication procedure for the remote controller 100 of the unauthorized access code. The authentication procedure can be performed through various known methods.

The authentication processing unit 210 may compare the access code provided by the remote controller 100 with a preset condition and give the remote controller 100 the authority to control the function of the controlled device 200. [ For example, when the access code from the remote controller 100 is an access code of a youth user, the authentication processing unit 210 can perform the function of the controlled device 200 only at a predetermined time such as 8:00 am to 10:00 pm You can also grant permission to control.

The image providing unit 220 provides control image data for displaying a control image. The control image may be an image including a selection button capable of appropriately controlling the function of the controlled device 200. [ For example, when the controlled device 200 is a TV, the control image includes a channel change button, a volume control button, a channel selection button, a VOD button, a game button, and the like as shown in FIG. 3C . The control image data is stored in advance in the control image storage, and the image providing unit 220 controls the control image data according to the functions currently provided by the controlled device 200 or according to the control menu selection step of the current user Can be extracted and provided from the image repository.

The control image provided in the image providing unit 220 is not fixed as being set at the time of production of the controlled device 200 but may be changed according to expansion of functions such as updating of the software of the controlled device 200. [ In addition, the control image provided by the image providing unit 220 may be provided differently according to the authority granted by the authentication accepting unit 210. [ For example, in the example shown in FIG. 3 (c), a control picture may be provided to the unauthorized user, except for the VOD button or the game button.

In addition, the image providing unit 220 may provide a lower control image in response to user's coordinate input or voice input to the control image. For example, when "channel selection" is selected by the user's input in the example of Fig. 3 (c), the lower control image may be a channel input image as shown in Fig. 3 (d).

The voice remover 230 can provide voice data of the announcement voice to be reproduced by the remote controller. The announcement voice is reproduced together with the control image displayed on the remote controller 100, so that the user can be notified of the selectable function. For example, the control image of FIG. 3 (d) is displayed on the remote controller 100, and a voice such as "Please input the desired channel number" can be reproduced. The announcement voice data is stored in advance in the announcement voice storage, and the voice data providing unit 230 guides the appropriate announcement voice data according to the function currently provided by the controlled device 200 or according to the control menu selection step of the current user It can be extracted from voice storage and provided. The voice data provided in the voice remover 230 is not fixed as being set at the time of production of the controlled device 200 but may be changed according to expansion of functions such as updating of the software of the controlled device 200. [

The data transmission unit 240 transmits the control image data provided by the image providing unit 220, the announcement voice data provided by the voice providing unit 230, or the authentication data required for the authentication in the authentication processing unit 210, (100). The control data receiving unit 250 receives coordinate input data or voice input data from the remote controller 100 as control data. The data transmission unit 240 and the control data reception unit 250 can communicate with the remote controller 100 using a wireless communication technology such as WiFi, Bluetooth, UWB, Zigbee, infrared communication, ultrasonic communication, .

The control command analysis unit 260 compares the control data received from the remote controller 100 with a control image currently provided to the remote controller 100 and converts the control data into a control command. Specifically, the control command analysis unit 260 can extract a control command corresponding to the coordinate input from the relationship table of the coordinate-control command stored in association with the provided control image. In addition, the control command analyzing unit 260 can extract a control command corresponding to the voice input from the relationship table of the voice-control command stored in association with the provided control image.

The function performing unit 270 generates a control signal for executing the function of the controlled device 200 in accordance with the analyzed control command or the image providing unit 220 sends a lower control image for detailed selection to the remote controller 100, . The function performing unit 270 may generate a control signal for executing another function or an additional function according to the authority granted by the authentication accepting unit 210. [ For example, when the authority approved by the authentication approval unit 210 is a youth authority and the control command is a command to change to an adult channel, a control signal is generated to output an error message on the TV screen, May be generated.

FIG. 2 is a flowchart illustrating a remote control method according to an embodiment of the present invention, and FIG. 3 is an exemplary view showing an example of a control image displayed on a remote controller according to an embodiment of the present invention. Hereinafter, a remote control method according to an embodiment of the present invention will be described with reference to FIG. 2 and FIG.

Referring to FIG. 3 (a), the remote controller 100 displays a list of controlled devices capable of wireless communication with the display device (S10). The user selects an object to be controlled by selecting one of the controlled devices from the displayed list of controlled devices (S20). The remote controller 100 requests connection to the controlled device selected by the user (S30).

When the remote controller 100 is requested to be connected, the controlled device 200 checks whether the remote controller 100 is authorized to control the controlled device 200 (S40). For example, the remote controller 100 checks whether the access code provided with the connection request is an approved access code. If the remote controller 100 is not authorized to control the controlled device 200, the authentication process is performed to grant the authority (S45).

For example, as shown in FIG. 3 (b), an authentication procedure can be performed through an authentication method using a PIN (Personal Identification Number) input. The image providing unit 220 of the controlled device 200 provides the PIN input image for authentication to the remote controller 100 and the image display unit 140 of the remote controller 100 displays the PIN input image on the display device do. The coordinate input unit 160 of the remote controller 100 obtains coordinate input from the user, for example, coordinates of the touch point in the touch display device, and the control data transmission unit 180 transmits the coordinates input to the controlled device 200). The control command analyzing unit 260 of the input device 200 interprets the PIN input data by comparing the coordinate input from the user with the PIN input image and the authentication processing unit 210 of the controlled device 200 determines whether or not the authentication is performed . Although the authentication procedure using the PIN is illustrated, the authentication procedure is not limited thereto and may be performed through various other known methods.

Thereafter, the image providing unit 220 of the controlled device 200 provides a control image for controlling the controlled device 200 to the remote controller 100 (S50). The control image can be selected from the control image storage according to the current function execution state of the controlled device 200. [ For example, as shown in Fig. 3 (c), a control image including a channel change button, a volume control button, and the like that can control the basic functions of the TV can be provided. Also, when the control image is transmitted to the remote controller 100, the voice data providing unit 230 of the controlled device 200 can provide the guidance voice together.

The image display unit 140 of the remote controller 100 displays the control image received from the controlled device 200 in the display device (S60). At this time, the voice reproducing unit 150 of the remote controller 100 can reproduce the guidance voice received from the controlled device 200. [

The coordinate input unit 160 of the remote controller 100 can obtain coordinate input from the user, for example, coordinates of a point touched by the user on the control image (S70). Also, the voice input unit 170 can obtain voice input from the user. When a coordinate input or a voice input is obtained from the user, the control data transmitting unit 180 transmits coordinate input data or voice input data to the controlled device 200 (S80). The remote controller 100 merely transmits coordinate input or voice input from the user to the controlled device 200 and does not need to interpret the control command in association with the control image displayed on the display device. The interpretation of the control command is performed in the controlled device 200.

The control command analysis unit 260 of the controlled device 200 compares the received coordinate input data or voice input data with the control image currently provided to the remote controller 100 to interpret the control command (S90). For example, the coordinate input received from the remote controller 100 interprets which point or which button of the control image provided to the remote controller 100 is pointing. That is, the control command interpreting unit 260 can extract a control command corresponding to the coordinate input from the relationship table of the coordinate-control command stored in association with the control image. The control command analysis unit 260 can extract a control command corresponding to the voice input from the voice-control command relationship table stored in association with the control image, from the voice input received from the remote controller 100. [

The function execution unit 270 of the controlled device 200 determines whether the control input from the remote controller 100 is a control command that can immediately execute a function or an additional control command (S100) When a control command is required, the image providing unit 220 controls the remote controller 100 to provide an additional control image. If an additional control command is not required, a control signal for controlling the component of the controlled device 200 related to the function of the control command to execute the function is generated (S110).

For example, in the example of FIG. 3 (c), when the user is interpreted as pressing the "Select Channel" button, it is necessary to additionally input the channel number from the user. Therefore, the function performing unit 270 controls the image providing unit 220 to provide the channel number input image as shown in FIG. 3 (d) to the remote controller 100.

3C, when the user interprets that the volume increase button is pressed, the function performing unit 270 generates a control signal for increasing the volume and increases the volume in the volume control unit of the TV .

In the remote control system of the present invention described above, the remote controller displays the control image using the control image data received from the controlled device, receives the coordinate input or the voice input from the user, and transmits it to the controlled device, It can perform the functions of the controller. That is, the remote controller of the present invention does not need to generate a separate control image according to the function of the controlled apparatus or to generate a separate control command from the user's input.

Therefore, the remote controller of the present invention does not need to include a calculation device for processing complicated calculations. The remote controller of the present invention needs only a minimum specification for image display, audio reproduction, user's coordinate input or voice input, .

In addition, since the control image for controlling the controlled device is generated in the controlled device, the remote controller does not need to be updated in accordance with the function expansion of the controlled device, and even if a new controlled device is added, no need.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the foregoing detailed description, and all changes or modifications derived from the meaning and scope of the claims and the equivalents thereof are included in the scope of the present invention Should be interpreted.
