FIGS. 4 to 10 are diagrams referred to in explanation of a spatial remote controller pairing method and a method of operating a video display device according to an embodiment of the present invention.

4 is a flowchart illustrating a method of pairing the image display apparatus 100 with the first spatial remote controller 201 according to the first embodiment of the present invention.

When the paired spatial remote controller does not exist, the image display apparatus 100 outputs a pairing request signal to the outside (S10). The image display apparatus 100 with the pairing transmits and receives signals through a predetermined frequency band with the paired spatial remote controller. However, the video display device 100 to which the pairing has been performed outputs a pairing request signal through all frequency bands capable of transmitting and receiving signals.

The pairing of the first spatial remote controller 201 and the second spatial remote controller 205 is not completed. Accordingly, the first and second spatial remote controllers 201 and 205 respond to a pairing request signal transmitted through all frequency bands capable of transmitting and receiving signals. In the present embodiment, the first spatial remote controller 201 and the second spatial remote controller 205 output a signal corresponding to the pairing request signal to the outside (S20).

The image display apparatus 100 receives a signal transmitted from the first and second spatial remote controllers 201 and 205 and displays a predetermined pattern on the display 170 of the image display apparatus 100 and the first and second spatial remote controllers 201 and 205 (S25). ≪ / RTI > The user can move the first and second spatial remote controllers 201 and 205 to match the predetermined pattern displayed on the display 170 by using the spatial remote controller desired to pair with the image display apparatus 100. [ The image display apparatus 100 compares a pointer corresponding to the first and second spatial remote controllers 201 and 205 with a predetermined pattern displayed on the display 170 to determine which one of the first and second spatial remote controllers 201 and 205 It is possible to determine whether the user wants to pair with a space remote controller.

If the user moves the first spatial remote controller 201 to correspond to the operation pattern displayed on the display 170 in step S30 and the second spatial remote controller 205 does not move or moves differently from the motion pattern in step S35, The display apparatus 100 displays a pointer on the display 170 to correspond to the movement of the first and second spatial remote controllers 201 and 205 (S40). When the image display apparatus 100 determines that the pointer corresponding to the first spatial remote controller 201 corresponds to the operation pattern, the image display apparatus 100 transmits a pairing signal containing the identification information of the image display apparatus 100 and the first spatial remote controller 201 And outputs the signal through the entire frequency band capable of transmitting and receiving signals (S45).

The first and second spatial remote controllers 201 and 205 receive a pairing signal transmitted from the image display apparatus 100. [ The space remote controller receiving the pairing signal confirms the identification information of the space remote controller included in the pairing signal. In this embodiment, the pairing signal includes identification information of the first spatial remote controller. Accordingly, the first spatial remote controller 201, which matches the identification information of the spatial remote controller included in the pairing signal, outputs a signal corresponding to the pairing signal to the image display device 100 (S50). The second spatial remote controller 205 differs from the identification information of the spatial remote controller included in the received pairing signal and the identification information of the second spatial remote controller and does not output a corresponding signal to the image display device (! 00).

The image display apparatus 100 ends the pairing process when receiving a signal corresponding to the pairing signal output to the outside (the signal transmitted from the first spatial remote controller 201 in this embodiment) (S55).

In the present embodiment, the image display apparatus 100 displays identification information of a spatial remote controller that moves according to a pattern in a pairing signal, in order to perform pairing with a spatial remote controller moved by a user in accordance with a pattern displayed on the display 170, . Therefore, if only one spatial remote control unit can be paired with the image display apparatus 100 or only one signal transmitted from the spatial remote controller corresponds to the pairing request signal output from the image display apparatus 100, The base station 100 may not include the identification information of the spatial remote controller in the pairing signal.

FIG. 5 is a diagram referred to the explanation of the image display apparatus 100 and the first and second spatial remote controllers 201 and 205 according to an embodiment of the present invention.

The PAIR_REQUEST field indicates whether the video display device is currently paired. When the PAIR_REQUEST field is TRUE, the current video display device is not paired with the predetermined space remote controller. Accordingly, the image display device periodically outputs a pairing request signal to the periphery of the image display device and detects whether there is a space remote controller to pair with the surroundings. When the PAIR_REQUEST field is FALSE, the current video display device is in a state of being paired with the predetermined space remote controller. Therefore, the image display apparatus no longer outputs the pairing request signal to the outside.

The AF_STATE field is a field indicating the state of the Address Filter. AF_STATE is OFF so that the image display device or the space remote controller can transmit / receive signals through all the frequency bands that can transmit / receive signals before the pairing is completed. In this case, PAIR_FIELD, which stores identification information for pairing, is ignored. When AF_STATE is ON, the image display device or the spatial remote controller checks the PAIR_FIELD and then filters and receives only the signal transmitted by the device having the PAIR_FILED information.

PAIR_FIELD indicates identification information for pairing. The PAIR_FIELD of each image display device can be changed during the hardware design process, and the basic design is displayed as a 32 bit value. This value can usually be generated by a random number. If PAIR_REQUEST is TRUE, the PAIR_FIELD of the video display device is input with the serial information of the video display device or the information generated through random number generation.

PAIR_STATE is a field storing the pairing information of the individual space remote controller. If PAIR_STATE is TRUE, the spatial remote control is paired. If PAIR_STATE is FALSE, the spatial remote controller is not paired.

5 (a) shows a state in which the video display device 100 and the first and second spatial remote controllers 201 and 205 are not paired with each other. In this case, the image display apparatus 100 periodically outputs a pairing request signal to the outside, and confirms the intensity of the signal transmitted by the spatial remote controller corresponding to the outputted pairing request signal. Since the image display apparatus 100 is not paired, AF_STATE is set to OFF so that all the surrounding spatial remote controllers receive signals transmitted corresponding to the pairing request signal.

When it is determined that the intensity of the received signal is greater than a predetermined intensity, which corresponds to one reference value, the image display apparatus 100 confirms the PAIR_STATE of the corresponding spatial remote controller. A space remote controller with PAIR_STATE of FALSE is not paired. In this embodiment, both the first and second space remote controllers are in a state where PAIR_STATE is FALSE. Accordingly, the image display apparatus 100 can display the UI on the display 170 or ask the user whether to pair the corresponding space remote controller. If the user selects to pair the corresponding space remote controller with the image display apparatus 100, the image display apparatus 100 displays an operation pattern that the user must follow in order to pair the space remote controller with the image display apparatus 100 (170).

The user moves the spatial remote controller that he wants to pair with to correspond to the motion pattern displayed on the display 170. [ In this embodiment, the user wants to pair the first spatial remote controller 201 of the first and second spatial remote controllers 201 and 205 with the image display apparatus 100. Accordingly, the user moves the first spatial remote controller 201 along the operation pattern displayed on the display 170. [

The image display apparatus 100 displays a pointer corresponding to the movement of the first and second spatial remote controllers 201 and 205 on the display 170 together with the operation pattern. Accordingly, the user can confirm whether or not the motion of the current spatial remote controller corresponds to the motion pattern displayed on the display 170. [ When the pointer of the spatial remote controller corresponds to the operation pattern, the video display device 100 outputs the pairing signal to the outside.

As shown in FIG. 5 (b), the image display apparatus 100 includes a pairing signal PAIR_FIELD that can be used as identification information of the image display apparatus and an ID that can be used as identification information of the spatial remote controller. In this embodiment, the ID of the first spatial remote controller 201 is A, and the ID of the second spatial remote controller 205 is B.

The spatial remote controller that matches the identification information of the spatial remote controller included in the pairing signal among the first and second spatial remote controllers 201 and 205 that received the pairing signal transmitted from the image display apparatus 100 is the first spatial remote controller 201 . Therefore, the first spatial remote controller 201 fills the PAIR_FIELD with the information corresponding to the PAIR_FIELD included in the pairing signal of the image display apparatus 100. The PAIR_FIELD of the second spatial remote controller 205 that is not matched with the identification information of the spatial remote controller is still empty.

The first spatial remote controller 201 fills PAIR_FIELD and transmits a response signal to the image display device 100 for the pairing signal. As shown in Fig. 5 (c), PAIR_STATE of the first spatial remote controller filled with PAIR_FEILD is changed to TRUE, and AF_STATE is also changed to ON.

The image display apparatus 100 receiving the response signal transmitted from the first spatial remote controller 201 regards the pairing as completed. Therefore, PAIR_REQUEST is changed to FALSE and the image display apparatus 100 no longer outputs a pairing request signal to the outside. Also, AF_STATE is changed to ON to start address filtering. That is, the image display apparatus 100 performs an operation corresponding to the same signal as that of the image display apparatus 100, the information of PAIR_FIELD among the received signals. Also, a signal of which the PAIR_FIELD information is not the same as the information of the image display apparatus 100 is ignored.

6 is a flow chart referred to in explanation of a method of operating a video display device according to an embodiment of the present invention. As shown in the figure, when there is no paired spatial remote controller, the video display device 100 outputs a pairing request signal to the outside (S100).

When the spatial remote controller existing in the vicinity transmits a response signal corresponding to the pairing request signal output by the image display apparatus 100, the image display apparatus 100 determines whether the intensity of the received response signal is equal to or higher than a predetermined intensity, (S105). If the strength of the received response signal is not equal to or greater than a reference value, the image display apparatus 100 may terminate the pairing. In this case, the image display apparatus 100 may display a pairing end window on the display 170 asking the user whether to end the pairing process (S110). If the user wishes to terminate the pairing process, the pairing process ends. If the user does not wish to terminate the pairing process, the video display device 100 periodically outputs a pairing request signal to the outside.

On the other hand, if the signal received in response to the pairing request signal is greater than or equal to a predetermined intensity, the image display apparatus 100 determines whether the PAIR_STATE of the spatial remote controller that transmitted the signal is FALSE (S115). If the PAIR_STATE of the spatial remote control is TRUE instead of FALSE, the spatial remote control is a space remote control that has already been paired. In this case, the image display apparatus 100 may confirm to the user whether to proceed the pairing process further (S110), and may terminate the pairing process or output the pairing request signal to the outside again.

If the PAIR_STATE of the spatial remote controller is FALSE, the image display apparatus 100 displays a pointer corresponding to the movement of the spatial remote controller in response to the pairing operation pattern and the pairing request signal on the display 170 (S120). The user must move the spatial remote controller to correspond to the operation pattern displayed on the display 170 in order to pair the spatial remote controller with the image display device.

The image display apparatus 100 confirms whether the motion of the spatial remote controller corresponds to the motion pattern through the pointer displayed on the display 170 (S125). The image display apparatus 100 moves the pointer so that the spatial remote controller corresponds to the motion. The image display apparatus 100 may display a window for confirming whether the pairing operation pattern displayed on the display 170 is reset if the movement of the pointer displayed on the display 170 does not correspond to the operation pattern.

If the user desires to reset the pairing operation pattern, the image display apparatus 100 resets the pairing operation pattern displayed on the display 170. [ The user can pair the spatial remote controller with the image display device by moving the spatial remote controller to correspond to the reset pairing operation pattern (S120, S125). If the user does not want to reset the pairing operation pattern, the video display device 100 displays a window 170 on the display 170 to confirm whether or not the pairing operation is terminated, thereby allowing the user to terminate the pairing process (S110).

If the user moves the spatial remote controller to correspond to the operation pattern, the image display device externally outputs the pairing signal including the identification information of the image display device and the spatial remote controller (S135). A spatial remote controller corresponding to the identification information included in the pairing signal among the spatial remote controllers existing in the vicinity of the image display apparatus 100 and receiving a signal output from the image display apparatus 100 to the outside, To the device (100).

When the image display apparatus 100 receives the signal transmitted by the spatial remote controller matching the identification information included in the pairing signal (S140), the pairing is completed. The image display apparatus 100 can display a pairing completion window on the display 170 (S145).

On the other hand, when the image display apparatus 100 does not receive a signal corresponding to the pairing signal output to the outside, the image display apparatus 100 outputs the pairing signal to the outside for a predetermined number of times before displaying the pairing error (S155) (S150). If the video display device fails to receive the corresponding signal even after outputting the pairing signal to the outside for a predetermined number of times, it is displayed on the display 170 that a pairing error has occurred (S155), and it is checked whether or not to terminate the pairing The pairing process can be terminated (S110).

7 to 10 are diagrams showing screens displayed on the video display device 100 according to an embodiment of the present invention.

7, the image display apparatus 100 displays a window 301 for confirming whether or not to proceed with the remote controller pairing to the user, upon receiving a signal indicating that the spatial remote controller has transmitted the corresponding signal after outputting the pairing request signal 170). In the present embodiment, the image display apparatus 100 displays the 301 window on the display 170 when the intensity of the signal transmitted by the spatial remote controller in response to the pairing request signal is higher than a predetermined intensity and the PAIR_STATE of the spatial remote controller is TRUE. When the user desires to pair, the user selects the icon 302.

8 is a screen displayed on the display 170 when the user wishes to pair. In FIG. 8A, the video display device 100 displays a window 311 corresponding to an operation pattern that the user should follow on the display 170. FIG. The user can move the spatial remote controller to correspond to the operation pattern displayed on the window 311. [

8 (b) is a view showing a screen displayed on the display 170 as the user moves the space remote controller. The image display apparatus 100 displays on the display 170 a pointer corresponding to the motion of the spatial remote controller. When the spatial remote controller is moved, the image display apparatus 100 moves the pointer corresponding to the movement, and displays the moving path 312 on the display 170. As shown in FIG. 8 (b), when the user moves the spatial remote controller to correspond to the operation pattern, the image display device 100 outputs a pairing signal including the corresponding spatial remote controller identification information to the outside.

8 (c), when the motion path 312 of the spatial remote controller is out of the line 313 of the operation pattern displayed on the display 170, the image display apparatus 100 displays It is judged that it has not moved to correspond to the pattern. In this case, the video display device 100 does not output a pairing signal to the outside.

9 is a diagram illustrating an operation pattern displayed on the display 170 of the image display apparatus 100 according to another embodiment of the present invention. The operation pattern displayed on the display 170 by the image display apparatus 100 may be various kinds. 8 (c), when the user can not move the spatial remote controller to correspond to the first operation pattern, the image display device 100 changes the appearance of the operation pattern displayed on the display 170 . In the present embodiment, the video display device 100 displays the 321 operation pattern on the display 170 as shown in Fig. 9 (a).

The user can move the spatial remote controller to correspond to the motion pattern 321. [ The movement path of the space remote controller is displayed on the display 170, as shown in Fig. 9 (b). In this embodiment, the spatial remote controller moves along the 322 motion path. The image display apparatus 100 determines that the spatial remote controller corresponds to the operation pattern and transmits the pairing signal to the outside.

10 (a) is a diagram referred to in explaining information filled in the PAIR_FIELD by the video display device 100. FIG. The PAIR_FIELD is included in a signal transmitted / received by the spatial remote controller paired with the image display device 100. Therefore, as the PAIR_FIELD increases, the traffic increases, and its size is limited depending on the hardware. If PAIR_FIELD is limited due to hardware limit, etc., serial number of video display device may not be all used as identification information. In this case, the image display apparatus 100 can fill the PAIR_FIELD by combining a part 331 of the serial number of the image display apparatus and the random number 332 generated through the random number generator.
