As a result, errors due to RF interference can be reduced and power efficiency can be increased.

In addition, the controller 280 extracts the reference value of the gyro sensor 131 stored in the memory 260 when performing the pairing operation with the image display device 100, and extracts the extracted reference value from the image display device ( 100). Accordingly, the controller 280 may perform an operation according to the movement of the remote control apparatus based on the reference value transmitted to the video display device 100.

Although the remote control apparatus 200 may be provided with a plurality of buttons as the user input unit 230, only one or two buttons may be provided in the remote control apparatus 200 as necessary. In addition, a plurality of buttons may be provided on the upper surface of the remote control apparatus 200, but some may be implemented to be provided on a surface other than the upper surface (for example, the side or the lower surface). In addition, the front surface of the remote control device 200 is movable in the space by the user. The front surface of the remote control apparatus 200 is movable in the space by the user in the up-direction, the down-direction, the left-direction, the right-direction, or a combination thereof (eg, the top-left). That is, the front surface of the remote control device 200 can move in any direction, including the rotation of the front surface as a reference axis.

In addition, when a touch panel is provided in the user input unit 230, a coordinate value for controlling a pointer displayed on the image display device 100 may be input through the touch panel. In addition, a control signal of the image display device 100 may be generated according to a gesture or a predetermined coordinate value input to the touch panel. The touch panel may be a touch screen provided with a display unit corresponding thereto. Since the user may input a key displayed on the touch screen, the user input unit 230 generates a control signal according to the key value input from the touch screen, and transmits the control signal to the control unit 280, whereby the control unit 280 remotely controls the control signal. The function of the apparatus 200 may be controlled or the generated control signal may be transmitted to the image display device 100.

4 is a flowchart illustrating a method of operating the video display device 100 according to an exemplary embodiment.

Referring to FIG. 4, the control unit 170 of the image display device 100 scans a remote control device located in the vicinity (S110). The controller 170 may scan the remote control apparatus located in the vicinity by determining whether the remote control apparatus 200 in proximity to the image display device 100 is present. In addition, the controller 170 may determine whether there is a remote control device located in the vicinity by using the wireless communication unit 137 or the scanning unit 139 described above. For example, the controller 170 may determine whether there is a remote control apparatus located in the vicinity by using the distance recognition module of the scanning unit 139 or the proximity communication module of the wireless communication unit 137.

In addition, the controller 170 determines whether the scanned remote control apparatus 200 is located within a predetermined distance from the image display device 100 (S120).

As described above, the controller 170 may determine whether the scanned remote control apparatus 200 is located within a predetermined distance by using the wireless communication unit 137 or the scanning unit 139. In some cases, the controller 170 may selectively determine whether the remote control apparatus 200 is located within a predetermined distance by selectively using the wireless communication unit 137 or the scanning unit 139.

Then, the controller 170 generates a pairing request signal of the first output to the remote control device 200 located within a predetermined distance, and transmits it through the wireless communication unit 137 (S130). The controller 170 may control the pairing request signal as a first output, and the first output may mean a signal strength of a low output for a close distance. Here, the control unit 170 may reduce the generation of radio wave interference to other devices in the vicinity according to the pairing request signal or the scan signal by controlling the output of the pairing request signal or the scan signal in the step S110 to the first output. . The controller 170 may transmit a pairing request signal of a first output to the scanned remote control apparatus 200 through, for example, a broadcasting channel or an advertising channel for close range.

In addition, the controller 170 determines whether a response signal to the pairing request signal of the first output is received (S140). The pairing request signal may include identification information of the video display device 100, and the pairing response signal may include identification information of the remote control apparatus 200 to perform pairing with the video display device 100.

If the response signal is not received, the controller 170 determines whether a predetermined time has elapsed (S145), and if it has elapsed for a predetermined time or more, determines that the pairing fails. When the pairing fails, the controller 170 may output a pairing failure message as a video or audio.

When the response signal is received from the remote control apparatus 200, the controller 170 generates a pairing start signal of the second output according to the received response signal (S150), and wirelessly generates a pairing start signal of the second output. It transmits through the communication unit 137 (S160). The controller 170 may generate a pairing start signal for starting pairing based on the identification information of the remote control apparatus 200 included in the received response signal. The pairing start signal may include pairing data for performing substantial pairing with the remote control apparatus 200, and may include an encryption code, device identification information, and the like for one-to-one communication.

Here, the controller 170 may control the pairing start signal as a second output. The second output may mean an output having a higher propagation intensity than the aforementioned first output. The controller 170 may perform a pairing process by performing a pairing request and response with a low first output and then raising the output to a second output when the remote control apparatus 200 to start pairing is confirmed. . As such, the controller 170 may prevent the pairing information from being broken due to RF environment interference by adjusting the first output and the second output. In addition, when the pairing device is not found, the controller 170 may reduce power consumption for transmitting a request signal, perform pairing by increasing its output only when substantial pairing data transmission and reception are required, and transmit and receive data.

When the pairing start signal is transmitted and the pairing performance data is received from the remote control apparatus 200, the controller 170 performs the subsequent pairing while maintaining the second output (S170). The control unit 170 transmits and receives pairing data (for example, the above-described encryption code, address information, identification information, control signal, etc.) to perform pairing with the remote control apparatus 200, and transmits and receives through the storage unit 140. The stored data may be managed, and the paired remote control devices 200 may be managed. The controller 170 may maintain pairing by transmitting / receiving pairing data of the second output with the paired remote control device.

The remote control apparatus 200 that communicates with the paired video display device 100 may transmit and receive various signals such as an image signal, an audio signal, and a data signal through the wireless communication unit 210 as well as a control signal. For example, the controller 280 may receive an image received from the paired image display device 100 and output the image through the display unit 251.

As illustrated in FIG. 6, a plurality of remote control apparatuses 200 within a predetermined distance scanned by the image display device 100 through the scanning unit 139 or the wireless communication unit 137 may exist. Accordingly, the video display device 100 may display a selection interface 102 for selecting a target to be paired among the remote control apparatuses 200, and the user wants to pair via the selection interface 102. The control device 200 can be selected.

Accordingly, the controller 280 may detect the pairing request signal received by the mode switching command included in the pairing request signal, or may switch to the pairing mode after transmitting the response.

In addition, when the mode is switched to the pairing mode, the controller 280 detects that the pairing start signal is received from the video display device 100 (S230), and performs pairing with the video display device 100 as a second output (S230). . The pairing start signal may be a signal of the second output as described above.
