Although the term used in the present invention is a general term that is widely used at present, there are some terms selected arbitrarily by the applicant in a specific case. In this case, since the meaning is described in detail in the description of the corresponding invention, It is to be understood that the present invention should be grasped as a meaning of a non-term.

That is, in the following description, the word 'comprising' does not exclude the presence of other elements or steps than those listed.

1 is a diagram illustrating a configuration of a display system according to an embodiment of the present invention.

Referring to FIG. 1, the display system includes a remote controller 100 for operating the display device 200 and a display device 200 for displaying an image.

The remote controller 100 transmits the operation contents of the user to the display device 200 and the display device 200 performs functions corresponding to the operation contents of the user received from the remote controller 100.

The display device 200 displays a broadcast received via wire or wireless and provides the display to a user. In addition, the display device 200 can display external input received from an external device connected via a wired or wireless connection and provide it to a user, but also can display a file (a moving image file, a still image file, File, etc.) can be reproduced and provided to the user.

2 and 3 are views for explaining the operation of the remote controller.

Referring to FIG. 2, the remote controller 100 includes a plurality of buttons. However, the remote controller 100 may include only one or two buttons, if necessary. 2, all of the plurality of buttons are provided on the upper surface of the remote controller 100, but some of them may be provided on a surface other than the upper surface (for example, a side surface or a lower surface) Do.

2, the front surface of the remote controller 100 is movable in space by the user. The front surface of the remote controller 100 is movable in an up-direction, a down-direction, a left-direction, a right-direction, or a combination thereof (for example, an upper left direction) by a user in space. That is, the front surface of the remote controller 100 is movable in any direction including the rotation with the front surface as the reference axis. Here, the remote controller 100 can communicate with the display device 200 in accordance with the RF communication standard.

2, a pointer 300 corresponding to the remote controller 100 may be displayed on the display device 200. [ The user can move or rotate the remote controller 100 up, down, left, right, back and forth. The pointer 300 displayed on the display device 200 corresponds to the movement of the remote controller 100. [

3 shows a state in which the pointer 300 displayed on the display device 200 moves in response to the movement of the remote controller 100. As shown in FIG.

3, when the user moves the remote controller 100 to the left, the pointer 300 displayed on the display device 200 moves correspondingly to the left. To this end, the remote controller 100 includes a sensor capable of determining movement. Accordingly, the remote controller 100 transmits information about the motion sensed through the sensor to the display device 200. [ The display device 200 determines the operation of the remote controller 100 from the information about the motion of the remote controller 100 and calculates the coordinate value of the pointer 300 corresponding thereto.

2 and 3 illustrate an example in which the pointer 310 displayed on the display device 200 moves in correspondence with the up, down, left, right, or rotation of the remote controller 100. FIG. That is, the movement trajectory of the pointer 310 according to the case where the remote controller 100 is moved leftward is described. Here, the movement speed and the movement direction of the pointer 300 may correspond to the movement speed and the movement direction of the remote controller 100.

In this embodiment, the pointer displayed on the display device 200 is set to move in response to the operation of the remote controller 100. [ As another example, in response to the operation of the remote controller 100, a predetermined command may be inputted to the display device 200. [ That is, when the remote controller 100 is moved back and forth, the size of the image displayed on the display device 200 can be enlarged or reduced. Therefore, the present embodiments are not intended to limit the scope of the present invention.

As a result, the front surface of the remote controller 100 is moved on a virtual plane (VP) by the user. That is, the front surface of the remote controller 100 can be moved in the upward-downward direction, the left-direction, the right-direction, or a combination thereof (for example, Do.

Accordingly, when the front surface of the remote controller 100 is moved on a virtual plane, the pointer 300 displayed on the display screen is moved in the same direction as the front surface of the remote controller 100 is moved. For example, when the user moves the front surface of the remote controller 100 in the upward direction on the virtual plane, the pointer 300 moves in the upward direction. When the user moves the front surface of the remote controller 100 to the left- The pointer 300 moves in the upper left direction as well.

4, the remote controller 100 includes a movement sensing unit 110, a transmission unit 120, a remote control unit 130, and a button input unit 140.

The movement sensing unit 110 senses the movement of the front surface of the remote controller 100 by the user and transmits the movement information according to the sensing result to the remote controller 130 to be described later. Here, the movement sensing unit 110 may be implemented using any one of a two-axis gyro sensor, a three-axis gyro sensor, a three-axis acceleration sensor, and a fingerprint recognition sensor. However, Lt; / RTI >

The remote controller control unit 130 transmits information (movement direction and movement distance) obtained through the sensing result received from the movement detection unit 110 to the display device 200 through the transmission unit 120. [

Particularly, the transmitter 120 transmits information on the moving direction and the moving distance of the remote controller 100 to the receiver 260 provided in the display device 200. Here, the transmitter 120 may be implemented using any one of a radio frequency (RF) module, a Zigbee, a bluetooth, and an Infra-Red.

5 is a diagram illustrating a configuration of a display device according to an embodiment of the present invention.

The broadcast receiving unit 210 is a means for receiving broadcast data from outside, and performs a function of receiving a video program through at least one means.

That is, the broadcast receiver 210 includes a digital tuner for receiving a digital broadcast signal, an analog tuner for receiving an analog broadcast signal, a digital external signal input terminal and an analog external signal input terminal to which an external device is connected, ) And a digital video recorder (DVR).

Here, the digital signal input terminal may be a digital cable broadcast signal input terminal or a digital external regenerator such as a DVD, and the analog external signal input terminal may be a VCR signal input terminal or an analog cable broadcasting signal input terminal.

In addition, the digital tuner tunes a transport stream of a desired channel by user selection among transport streams, which are digital broadcast signals inputted through a digital broadcast antenna. The analog tuner tunes an image program of a desired channel by user selection among image programs that are analog broadcast signals inputted through an antenna for analog broadcasting.

Accordingly, the broadcast data may include an analog television broadcast program, a digital broadcast program, a playback program, a recording program, and a cable broadcast program input from an external player in real time. Here, the broadcast data includes both a video signal, a voice signal, and a data signal in the case of a digital signal, and includes only a video signal and a voice signal in the case of an analog signal.

The broadcast data received through the broadcast receiver 210 is subjected to signal processing through the signal processor 220 and displayed on the display unit 240.

The signal processing unit 220 includes an MPEG-2 decoder and a scaler for converting the broadcast data to a vertical frequency, a resolution, an aspect ratio, and the like, according to an output standard of the display unit 240.

The display unit 240 may include various types of display modules such as a DLP (Digital Light Processing), an LCD (Liquid Crystal Display), a PDP (Plasma Display Panel), an LED (Light Emitting Diode lamp) Lt; / RTI >

The GUI generating unit 230 generates various types of menu screens such as a menu screen for setting the password of the display device and adds the menu screen to the video data received through the broadcast receiving unit 210. Here, the GUI generating unit 230 generates the OSD (On Screen Display) form of the menu screen, and the data generated in the OSD form may be character data or graphic data.

The character data may be a notification message indicating that the user can not receive the requested video program. Also, the graphic data may be a pointer of the remote controller 100 for inputting a user request condition. The user can change the use condition of the display device by selecting a desired menu item by using the pointer generated through the GUI generation unit 230. [

The memory unit 250 stores software related to the operation of the display apparatus 100 and various data generated during operation of the display apparatus 200. [

The memory unit 150 may be implemented as an EEPROM (Electrically Erasable Programmable Read-Only Memory), and may be connected to a controller 270, which will be described later, according to an I2C scheme. In addition, the memory unit 150 stores movement locus information of the remote controller 100 set as a password. The stored movement trajectory information will be described in detail below.

The receiving unit 260 receives a signal input for the operation of the display device 200 through the remote controller 100 and transmits the received signal to the controller 170. [ The input signal may be key code information corresponding to a specific key button provided in the remote controller 100 or may be movement information according to the movement (movement direction) of the remote controller 100. [

The control unit 270 controls the overall operation of the display device 200.

In particular, the controller 270 sets a password for permission to use the access, based on the movement trajectory according to the movement information transmitted from the remote controller 100.

That is, in the embodiment of the present invention, the user password can be set based on the movement locus of the remote controller 100.

A commonly used password setting method is to set a user password by inputting at least one numeric key button among the numeric key buttons provided in the remote controller 100 and storing a key code corresponding to the inputted numeric key button. However, such a method has a problem in that it is difficult to access when a user forgets a numeric key set by a password.

In addition, a method of setting a password using a space remote controller displays an OSD (On Screen Display) for inputting a separate password on a display screen of a display device, and a user can use a pointer displayed on the OSD By selecting a character, a password is set.

That is, in the first method or the second method, a password is set by inputting a key corresponding to a character set by the user as a password.

However, in the embodiment of the present invention, the user moves the remote controller 100 in any direction desired by the user, and accordingly, the controller 270 determines a movement locus corresponding to the movement information of the remote controller 100 So as to control the password setting.

Hereinafter, an encryption setting process performed through the controller 270 will be described in detail with reference to the accompanying drawings.

When the password setting command is inputted through the remote controller 100, the control unit 270 displays a menu screen for setting the password.

FIG. 6 is a diagram illustrating an example of a menu screen for password setting according to an embodiment of the present invention.

Referring to FIG. 6, a menu screen 600 for setting a password includes a movement locus display area 610 on which the movement locus information of the remote controller 100 inputted by the user is displayed.

That is, the control unit 270 displays the moving sign information corresponding to the password input by the user in the moving sign display area 610 based on the movement information transmitted from the remote controller 100 for setting the encryption.

Accordingly, the user confirms the movement locus information displayed in the locus display region 610, and determines how the remote controller 100 is currently moving in accordance with the movement locus, So that it can be clearly confirmed.

At this time, the movement trajectory set by the password corresponds to any one or two or more combinations of a user signature / sign, a specific character, a pattern, and a movement locus corresponding to a figure and a number.

For example, when '2' is set as a password, the user inputs a numeric key button corresponding to the '2' among the key buttons provided on the remote controller 100, or when the '2' By selecting the area, password input was performed. However, in such a case, there is a problem that security of the set password is difficult to maintain.

In other words, when the password is set as described above, only the key button set with the password can be input. Therefore, if the password is set to the 4-digit number, the numbers from 0000 to 9999 are sequentially input, Even an outsider who does not know it can easily find out the set password.

However, in the embodiment of the present invention, since the cipher is set with the movement trajectory of the remote controller 100 corresponding to an arbitrary shape (sign / sign, character, pattern, figure, number) It is possible to securely maintain the security state.

For example, when a password is set using the movement trajectory of '2', since the shape of '2' is different for each user who sets a password even if the same '2' shape is used, Only the shape of '2' set to the above-mentioned password can be accurately input, thereby enabling to secure secure password security.

7 is a diagram illustrating a cipher set according to an embodiment of the present invention.

As shown in FIG. 7, (a) shows a case in which a personal trajectory of a shape corresponding to a user's personal signature or sign is input by using the remote controller 100. In this case, since the personal signature or sign is a character that can be known only to the user, it is possible to set a more secure password. (b) shows a case where a moving locus corresponding to a specific figure is input using the remote controller 100. [ In this case, since the shape of the figure is different for each user even in the same figure, only the user who sets the password can correctly input the set password, so that the security of the set password can be maintained. (C) shows a case in which a movement locus of a shape obtained by combining a plurality of figures, patterns, letters, and numbers by using the remote controller 100 is input. In this case, there is an advantage that more secure password security can be performed than in the case of (b).

When the movement trajectory of the remote controller 100 inputted from the user is confirmed on the menu screen 600, the controller 270 requests retransmission of the movement information of the remote controller 100.

That is, in the embodiment of the present invention, the password can be set using the movement trajectory of the remote controller 100 that has been checked. However, in order to set the more accurate password, And the like.

As shown in FIG. 8, the controller 270 displays a menu screen 800 for re-entering the password. The menu screen 800 for re-inputting the password includes a movement locus display region 810, and the user can use the information displayed on the movement locus display region 810 to display the remote controller 100 can be accurately confirmed.

As described above, when a plurality of movement trajectories are input, the control unit 270 compares the input trajectories inputted over the plurality of times, and determines whether there is a difference in the input movement trajectory as a result of the comparison.

At this time, when the movement trajectories inputted through the plurality of times are equal to each other, the control unit 270 stores the movement trajectory information in the memory unit 250, thereby setting the input trajectory as a password.

Meanwhile, when the movement trajectory inputted through the plurality of times is different from each other, the control unit 270 grasps a different degree of the movement trajectory and re-enters the movement trajectory for setting the password according to the degree of the movement trajectory , Or sets the inputted movement locus as a password.

That is, when the movement trajectory inputted over the plurality of times is different from the preset error range, the controller 270 displays the menu screen 600 as shown in FIG. 6, So that the encrypted password is set again.

If the movement trajectory inputted through the plurality of times is different to a degree within a predetermined error range, the control unit 270 checks the degree of difference of the plurality of movement trajectories, Is set to an error range of the movement locus.

For example, if the first input movement trajectory is in a horizontal state '→' and the second input trajectory is a '→' shape that is inclined at 30 degrees, the control unit 270 outputs the input '→' And sets the error range of the set password to 30 degrees accordingly. Accordingly, the controller 270 determines that an accurate password has been input for the movement trajectory of the " - " shape input from 0 to 30 degrees.

When the encryption is set up as described above, the controller 270 stores the movement locator information and the error range information set in the encryption in the memory unit 250.

In addition, the controller 270 provides the set encryption information as a flash-like moving picture, so that the user can clearly recognize the movement trajectory of the currently set password.

FIG. 9 is a diagram showing an encryption information providing screen formed by an embodiment of the present invention. FIG.

9, the password information providing screen 900 includes an encryption information providing area 910. In the encryption information providing area 910, moving sign information set by a user as a password is stored in the password information providing area 910 Is displayed. At this time, the displayed moving trajectory information is provided as moving images based on the starting point to the end point of the moving trajectory set by the encryption. Accordingly, the user can finally check the movement locus of the remote controller 100 set as the password.

In addition, the control unit 270 separately manages the trajectory set by the password by user accounts. That is, since the movement trajectory set by the password is set in a shape suited to individual taste, it is not easy to input the movement locus corresponding to the set password even when another user recognizes the set password. Accordingly, the control unit 270 distinguishes and stores the movement locus information set as the cipher for each user, and determines whether to use the user who requested the access permission, using the movement locus information classified by the user .

If the password is set as described above, the controller 270 determines whether to use the access using the set password.

That is, when a specific movement locus is input through the remote controller 100, the control unit 270 compares the input locus with the pre-stored locus, Permit access to use or restrict access to use, depending on whether they match.

At this time, if the inputted trajectory is included within the error range in the stored trajectory, the controller 270 determines that the normal password is input and permits the use access based on the set error range.

However, when the inputted trajectory is out of the error range in the stored trajectory, the controller 270 determines that an abnormal password is input, and restricts the use access.

According to the display device of the present invention configured as described above, it is possible to compensate for the weakness of the existing number-based password security function, and it is possible to improve the security of the display by using the signature / signature of the user, It is possible to set the password of the device, thereby improving the user's convenience.

Hereinafter, a method of setting a password of a display device according to an embodiment of the present invention will be described.

10 is a flowchart for explaining a step of setting a password of a display device according to an embodiment of the present invention.

Referring to FIG. 10, the controller 270 determines whether a command for setting a password is input through the remote controller 100 (operation 100).

When the command for setting the password is input, the controller 270 controls to display a menu screen for setting an encryption (step 110). That is, the controller 270 displays the menu screen 600 as shown in FIG. 6, and sets the password using the movement trajectory of the remote controller 100.

When the movement information is transmitted through the remote controller 100 in a state where the menu screen 600 is displayed, the controller 270 analyzes the transmitted movement information and transmits the movement information to the movement information of the remote controller 100 (Step 120).

The control unit 270 determines the movement trajectory to be set as a cipher to be set, and causes the movement trajectory set in the cipher to be re-inputted in operation 130. That is, the controller 270 displays the password re-input screen 800 as shown in FIG. 8, and re-inputs the movement locus of the remote controller 100 to be set by the user.

When the movement trajectory of the remote controller 100 is re-input in response to the request for re-encryption, the controller 270 compares the re-inputted movement locus with the firstly inputted movement locus, An error range of the locus is set (step 140). That is, for example, when the first input movement trajectory is a horizontal → → shape and the second input movement trajectory is a → → shape tilted at 30 degrees, the control unit 270 outputs the input → Is set to a password, and the error range of the set password is set to 30 degrees accordingly. Accordingly, the controller 270 determines that an accurate password has been input for the movement trajectory of the " - " shape input from 0 to 30 degrees.

The control unit 270 stores the input moving sign information and the set error range information in the memory unit 250 (step 150). At this time, the controller 270 stores the moving sign information and the error range information in the account of the user who has requested the password setting, and distinguishes it from the password set by another user.

11 is a flowchart illustrating a step-by-step description of a method for unlocking a display device according to an embodiment of the present invention.

Referring to FIG. 11, the controller 270 determines whether user authentication is requested through the remote controller 100 (operation 200). The user authentication request may be performed when a specific key button included in the remote controller 100 is input, and may be performed when a pointer displayed on the display screen selects a user authentication request menu.

If there is a user authentication request, the controller 270 displays a menu screen for performing user authentication (operation 210). The menu screen may include a movement locus input window for inputting a password, and the movement locus of the remote controller 100 input from the user may be displayed in the locus input window.

When the movement information is transmitted through the remote controller 100 in a state where the menu screen is displayed, the controller 270 analyzes the transmitted movement information and displays the movement locus of the remote controller 100 It is determined whether the movement locus is the same as the previously stored locus locus (step 230).

If the determined movement locus is identical to the previously stored movement locus, the controller 270 determines that a normal password has been input, and permits the use access in operation 240.

In step 250, the controller 270 determines whether the two movement trajectories are within the pre-stored error range when the detected movement trajectory is different from the previously stored movement trajectory.

If the two movement trajectories are within the error range, the control unit 270 determines that the normal password is input and permits the use access (step 260). If it is determined that the two movement trajectories are out of the error range, It is determined that the input has been made and the use access is restricted (step 270).

As described above, according to the embodiment of the present invention, it is possible to compensate for the weakness of the security function using the existing numbers, and it is possible to improve security of the display device by using signature / sign of the user, It is possible to set a password, thereby improving convenience for the user.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or essential characteristics thereof. .
