[0058] FIG. 1 is a schematic block diagram of a video display device according to one aspect of the present disclosure.

[0059] Referring to FIG. 1, a video display device (100) according to one aspect of the present disclosure may include a broadcast receiving unit (105), an external device interface unit (135), a storage unit (140), a user input interface unit (150), a control unit (170), a display unit (180), an audio output unit (185), a power supply unit (190), and a photographing unit (not shown). The broadcast receiving unit (105) and the external device interface unit (135) may be collectively referred to as a communication unit.

[0060] The broadcast receiving unit (105) may include a tuner (110), a demodulator (120), and a network interface unit (130). Of course, if necessary, it may be designed to include a tuner (110) and a demodulator (120) but not a network interface unit (130), and conversely, it may be designed to include a network interface unit (130) but not a tuner (110) and a demodulator (120).

[0061] The tuner (110) selects an RF broadcast signal corresponding to a channel selected by the user or all pre-stored channels among RF (Radio Frequency) broadcast signals received through an antenna. In addition, it converts the selected RF broadcast signal into an intermediate frequency signal or a baseband video or audio signal.

[0062] For example, if the selected RF broadcast signal is a digital broadcast signal, it is converted into a digital IF signal (DIF), and if it is an analog broadcast signal, it is converted into an analog baseband video or audio signal (CVBS / SIF). That is, the tuner (110) can process both digital broadcast signals and analog broadcast signals. The analog baseband video or audio signal (CVBS / SIF) output from the tuner (110) can be directly input to the control unit (170).

[0063] Additionally, the tuner (110) can receive an RF broadcast signal of a single carrier according to the ATSC (Advanced Television System Committee) method or an RF broadcast signal of multiple carriers according to the DVB (Digital Video Broadcasting) method.

[0064] Meanwhile, the tuner (110) can sequentially select RF broadcast signals of all broadcast channels stored through a channel memory function among RF broadcast signals received through an antenna and convert them into intermediate frequency signals or baseband video or audio signals.

[0065] The demodulation unit (120) receives a digital IF signal (DIF) converted by the tuner (110) and performs a demodulation operation.

[0066] For example, if the digital IF signal output from the tuner (110) is in ATSC format, the demodulation unit (120) performs, for example, 8-VSB (8-Vestigal Side Band) demodulation. In addition, the demodulation unit (120) may also perform channel decoding. To this end, the demodulation unit (120) may be equipped with a Trellis Decoder, a De-interleaver, a Reed-Solomon Decoder, etc., and may perform Trellis decoding, deinterleaving, and Reed-Solomon decoding.

[0067] For example, if the digital IF signal output from the tuner (110) is in the DVB format, the demodulation unit (120) performs, for example, COFDMA (Coded Orthogonal Frequency Division Modulation) demodulation. In addition, the demodulation unit (120) may also perform channel decoding. To this end, the demodulation unit (120) may be equipped with a convolution decoder, a deinterleaver, a Reed-Solomon decoder, and the like, and may perform convolution decoding, deinterleaving, and Reed-Solomon decoding.

[0068] The demodulator (120) can output a stream signal (TS) after performing demodulation and channel decoding. At this time, the stream signal may be a signal in which a video signal, an audio signal, or a data signal is multiplexed. For example, the stream signal may be an MPEG-2 TS (Transport Stream) in which a video signal in the MPEG-2 standard and an audio signal in the Dolby AC-3 standard are multiplexed. Specifically, the MPEG-2 TS may include a 4-byte header and a 184-byte payload.

[0069] Meanwhile, the above-described demodulation unit (120) can be provided separately according to the ATSC method and the DVB method. That is, it can be provided as an ATSC demodulation unit and a DVB demodulation unit.

[0070] The stream signal output from the demodulation unit (120) can be input to the control unit (170). The control unit (170) performs demultiplexing, image / audio signal processing, etc., and then outputs the image to the display unit (180) and outputs the audio to the audio output unit (185).

[0071] The external device interface unit (135) can connect an external device and a video display device (100). To this end, the external device interface unit (135) may include an A / V input / output unit (not shown) or a wireless communication unit (not shown).

[0072] The external device interface unit (135) can be connected to external devices such as a DVD (Digital Versatile Disk), Blu-ray, game device, camera, camcorder, computer (laptop), etc., via wired / wireless connection. The external device interface unit (135) transmits a video, audio, or data signal input from the outside through the connected external device to the control unit (170) of the video display device (100). In addition, the video, audio, or data signal processed by the control unit (170) can be output to the connected external device. For this purpose, the external device interface unit (135) may include an A / V input / output unit (not shown) or a wireless communication unit (not shown).

[0073] The A / V input / output section may include a USB terminal, a CVBS (Composite Video Banking Sync) terminal, a component terminal, an S-video terminal (analog), a DVI (Digital Visual Interface) terminal, an HDMI (High Definition Multimedia Interface) terminal, an RGB terminal, a D-SUB terminal, etc., so as to input video and audio signals from an external device to the video display device (100).

[0219] The control unit (170) can control the shortcut user interface (500A, 500B, 500C) to disappear from the display (170) when a predetermined time has elapsed since the last operation of the user through the remote control device (200) or the mouse (300) for the shortcut user interface. Alternatively, the control unit (170) can control the shortcut user interface (500A, 500B, 500C) to disappear from the display (170) when the user positions the pointer (205) outside the shortcut user interface (500A, 500B, 500C) on the background screen and selects the background screen through the remote control device (200) or the mouse (300).

[0220] The shortcut user interface (500A, 500B, 500C) may include various menus in addition to the menus described above. For example, the shortcut user interface (500A, 500B, 500C) may further include at least one of a sound quality change menu, a speaker change menu, a screen brightness adjustment menu, a screen zoom in / out menu, and a black area automatic removal menu.

[0221] Hereinafter, with reference to FIG. 7, a control method for displaying a shortcut user interface by a video display device according to one aspect of the present disclosure will be described. FIG. 7 is a flowchart showing a method for displaying a shortcut user interface by a video display device according to one aspect of the present disclosure.

[0222] The video display device (100) can communicate with at least one of a remote control device (200) and a mouse (300) [S701].

[0223] The control unit (100) can display a pointer (205) according to the movement of a remote control device (200) or mouse (300) [S702].

[0224] The control unit (100) can display a shortcut user interface in response to receiving a control signal (e.g., a signal generated by a user operating the remote control device (200) or the mouse (300)) from the remote control device (200) or the mouse (300) when the pointer (205) is positioned at a specific location (e.g., a location where there are no selectable graphics or texts (e.g., menus, icons, and / or links, etc.) with the pointer (205)) [S703].

[0225] In the above, it has been explained that the pointer (205) can be controlled via a remote control device (200) or via a mouse (300). However, when the user is located relatively far away from the video display device (100), the pointer (205) is often controlled via the remote control device (200), and when the user is located relatively close to the video display device (100), the pointer (205) is often controlled via the mouse (300).

[0226] However, if the pointer (205) is displayed in the same shape and / or size regardless of whether the pointer (205) is controlled through a remote control device (200) or a mouse (300), this may be inconvenient for the user.

[0227] For example, when controlling a pointer (205) through a remote control device (200), the size of the pointer (205) can be made larger considering that the user is often positioned relatively far away from the video display device (100), and when controlling a pointer (205) through a mouse (300), the size of the pointer (205) can be made smaller considering that the user is often positioned relatively close to the video display device (100), which can be convenient for the user. In addition, when the shape of the pointer (205) is different between when controlling the pointer (205) through a remote control device (200) and when controlling the pointer (205) through a mouse (300), the user can intuitively know whether the pointer (205) is currently being controlled by the remote control device (200) or the pointer (205), which can be more convenient for the user.

[0228] In addition, if the sensitivity of the pointer (205) to the movements of the remote control device (200) and the mouse (205) is the same regardless of whether the pointer (205) is controlled through the remote control device (200) or through the mouse (300), this may be inconvenient for the user. For example, if the sensitivity of the pointer (205) is increased when controlling the pointer (205) through the remote control device (200) and decreased when controlling the pointer (205) through the mouse (300), it may be more convenient for the user.

[0229] First, referring to FIGS. 8 and 9, we will explain how the pointer displayed when controlled via a remote control device (200) and the pointer controlled via a mouse (300) have different shapes and / or sizes. FIG. 8 is a flowchart showing a display of a pointer in a video display device according to one aspect of the present disclosure. FIG. 9 is an example of a pointer displayed in a video display device according to one aspect of the present disclosure.

[0230] As illustrated in (9-1) of FIG. 9, a content screen (400) may be displayed on the display (180) of the video display device (100). The content screen may be a screen on which multimedia content (e.g., broadcasts, movies, games, web browsers, etc.) is displayed.

[0231] When the content screen (400) is being displayed, the control unit (170) can control the first pointer (205) to be displayed on the content screen (400), as shown in (9-1) of FIG. 9 [S801].

[0232] The first pointer (205) can be controlled by a mouse (300) connected to the video display device (100) by wired or wireless communication. The first pointer (205) can express the movement of the mouse (300) by moving in response to the movement of the mouse (300). The user can intuitively know that he or she is manipulating the mouse (300) by looking at the first pointer (205). The user can control the video display device (100) by moving the mouse (300) to move the first pointer (205) and / or manipulating at least one of the left button (311), the right button (312), and the wheel (313) of the mouse (300).

[0233] The remote control device (200) can be operated by the user while the first pointer (205) is displayed [S803]. For example, the user can move the remote control device (200) while the first pointer (205) is displayed. Alternatively, the user can operate one of the multiple buttons of the remote control device (200) while the first pointer (205) is displayed.

[0234] Then, in response to the operation of the remote control device (200), the control unit (170) can control the first pointer (205) to be switched to the second pointer (207) on the content screen (400), as shown in (9-2) of FIG. 9 [S805]. That is, the control unit (170) can control the second pointer (207) to be displayed at the location where the first pointer (205) was at the time the remote control device (200) was operated, instead of the first pointer (205) at the time the remote control device (200) was operated. The second pointer (207) may have at least one different shape and / or size from the first pointer (205).

[0235] The second pointer (207) can be controlled by the remote control device (200). The second pointer (207) can express the movement of the remote control device (200) by moving in response to the movement of the remote control device (200). The user can intuitively know that he or she is operating the remote control device (200) by looking at the second pointer (207). The user can control the video display device (100) by moving the remote control device (200) to move the second pointer (207) and / or by operating at least one of the plurality of buttons of the remote control device (200).

[0236] The second pointer (207) can also be moved in the corresponding direction by operating the direction key (292) of the remote control device (200).

[0237] Considering that the first pointer (205) is displayed when the mouse (300) is operated and the second pointer (207) is displayed when the remote control device (200) is operated, and that the mouse (300) is generally operated at a relatively close position to the image display device (100) and the remote control device (200) is generally operated at a relatively far position from the image display device (100), the size of the second pointer (207) may be larger than that of the first pointer (205).

[0238] The user may operate the mouse (300) while the second pointer (207) is displayed [S807]. For example, the user may move the mouse (300) while the second pointer (207) is displayed. Alternatively, the user may operate at least one of the left button (311), the right button (312), and the wheel (313) of the mouse (300) while the second pointer (207) is displayed.

[0239] Then, in response to the operation of the mouse (300), the control unit (170) can control the second pointer (207) to be switched to the first pointer (205) on the content screen (400), as shown in (9-1) of FIG. 9 [S801]. That is, the control unit (170) can control the first pointer (205) to be displayed at the location where the second pointer (207) was at the time the mouse (300) was operated, instead of the second pointer (207) at the time the mouse (300) is operated.

[0240] A pointer (205, 207) is displayed on the display (180) of the video display device (100) and can be moved on the screen. However, depending on whether the user operates the remote control device (200) or the mouse (300), the pointer (205, 207) can be controlled to have the shape and / or size of the first pointer (205) or the shape and / or size of the second pointer (207).

[0241] However, if a user or another person accidentally or unintentionally touches the remote control device (200) while the first pointer (205) is displayed, a problem may occur in which the first pointer (205) changes to the second pointer (207) against the user's intention. Or, if a user or another person accidentally or unintentionally touches the mouse (300) while the second pointer (207) is displayed, a problem may occur in which the second pointer (207) changes to the first pointer (205) against the user's intention. A method for preventing such a problem will be described with reference to FIGS. 10 and 11. FIG. 10 is a flowchart showing a pointer being displayed in an image display device according to one aspect of the present disclosure. FIG. 11 is an example of a pointer being displayed in an image display device according to one aspect of the present disclosure.

[0242] As illustrated in (11-1) of FIG. 11, a content screen (400) may be displayed on the display (180) of the video display device (100). The content screen may be a screen on which multimedia content (e.g., broadcasts, movies, games, web browsers, etc.) is displayed.

[0243] When the content screen (400) is being displayed, the control unit (170) can control the first pointer (205) to be displayed on the content screen (400), as shown in (11-1) of FIG. 11 [S1001].

[0244] As described above, the first pointer (205) can be controlled by a mouse (300) connected to the video display device (100) via wired or wireless communication. The display of the first pointer (205) may mean that the user is currently controlling the video display device (100) with the mouse (300).

[0245] The remote control device (200) can be moved while the first pointer (205) is displayed [S1003].

[0246] Then, in response to detecting the movement of the remote control device (200), the control unit (170) can control the first pointer (205) to be switched to the third pointer (209) on the content screen (400), as shown in (11-2) of FIG. 11 [S1005]. It goes without saying that the first pointer (205) can continue to be displayed if the movement of the remote control device (200) is not detected. The control unit (170) can control the third pointer (209) to be displayed at the location where the first pointer (205) was at the time when the movement of the remote control device (200) is detected, instead of the first pointer (205).

[0247] The display of the third pointer (209) can serve to inform the user that movement of a device other than the mouse (300) currently controlling the video display device (100) has been detected (i.e., a remote control device (200)).

[0248] If the third pointer (209) is displayed contrary to the user's intention, the user can allow a predetermined time to elapse without operating multiple buttons of the remote control device (200), or the user can operate the buttons of the mouse (300) even before the predetermined time elapses [S1007].

[0249] Then, the control unit (170) can control the third pointer (209) to be restored to the first pointer (205) [S1001]. Accordingly, by displaying the first pointer (205), the user can continue to control the video display device (100) using the mouse (300).

[0250] When the third pointer (209) is displayed according to the user's intention, the user can operate any one button or a specific button (e.g., a confirmation button (238)) among the multiple buttons of the remote control device (200) [S1007].

[0251] Then, the control unit (170) can control the third pointer (209) to be switched to the second pointer (207), as illustrated in (11-3) of FIG. 11 [S1009]. That is, the control unit (170) can control the second pointer (207) to be displayed at the location where the third pointer (209) was at the time the remote control device (200) was operated, instead of the third pointer (209) at the time the button of the remote control device (200) is operated. By displaying the second pointer (207), the user can control the image display device (100) using the remote control device (200). As described above, the user can control the image display device (100) by operating the remote control device (200) via the second pointer (207).

[0252] The mouse (300) can be moved while the second pointer (207) is displayed [S1011].

[0253] Then, in response to detecting the movement of the mouse (300), the control unit (170) can control the second pointer (207) to be switched to the third pointer (209) on the content screen (400), as shown in (11-2) of FIG. 11 [S1013]. It goes without saying that the second pointer (207) can continue to be displayed if the movement of the mouse (300) is not detected. The control unit (170) can control the third pointer (209) to be displayed at the location where the second pointer (207) was at the time the movement of the mouse (300) was detected, instead of the second pointer (207).

[0254] The display of the third pointer (209) can serve to inform the user that movement of a device other than the remote control device (200) currently controlling the video display device (100) has been detected (i.e., the mouse (300)).

[0255] If the third pointer (209) is displayed contrary to the user's intention, the user can allow a predetermined time to elapse without operating multiple buttons of the mouse (300), or the user can operate buttons of the remote control device (200) even before the predetermined time elapses [S1015].

[0256] Then, the control unit (170) can control the third pointer (209) to be restored to the second pointer (207) [S1009]. Accordingly, by displaying the second pointer (207), the user can continue to control the video display device (100) using the remote control device (200).

[0257] When the third pointer (209) is displayed according to the user's intention, the user can operate any one button among the multiple buttons of the mouse (300) or a specific button (e.g., wheel button (313)) [S1015].

[0258] Then, the control unit (170) can control the third pointer (209) to be switched to the first pointer (205), as illustrated in (11-1) of FIG. 11 [S1001]. That is, the control unit (170) can control the first pointer (205) to be displayed at the location where the third pointer (209) was at the time the mouse (300) is operated, instead of the third pointer (209) at the time the button of the mouse (300) is operated. By displaying the first pointer (205), the user can control the image display device (100) using the mouse (300). As described above, the user can control the image display device (100) using the mouse (300) via the first pointer (205).

[0259] Referring further to FIG. 12, it will be described that a user guide may also be provided when a third pointer (209) is displayed. FIG. 12 is an example of a pointer displayed on a video display device according to one aspect of the present disclosure.

[0260] When the third pointer (209) is displayed according to the steps S1001 to S1005 described above, the control unit (170) can control the display (180) to display the first guidance guide (610) together with the third pointer (209).

[0261] The first guidance guide (610) may be intended to guide the user that the third pointer (209) can be switched to the second pointer (207) when the user operates the button of the remote control device (200).

[0262] In response to the user's button operation of the remote control device (200), the control unit (170) can control the first guidance guide (610) to disappear while switching the third pointer (209) to the second pointer (207).

[0263] Meanwhile, when the third pointer (209) is displayed according to the steps S1009 to S1013 described above, the control unit (170) can control the display (180) to display the second guidance guide (620) together with the third pointer (209).

[0264] The second guidance guide (620) may be intended to guide the user that the third pointer (209) can be switched to the first pointer (205) when the user operates the button of the mouse (300).

[0265] In response to a button operation of the user's mouse (300), the control unit (170) can control the second guidance guide (620) to disappear while switching the third pointer (209) to the first pointer (205).

[0266] If the sensitivity of the pointer remains the same when the first pointer (205) is switched to the second pointer (207) directly or via the third pointer (209), or when the second pointer (207) is switched to the first pointer (205) directly or via the third pointer (209), it may be inconvenient for the user.

[0267] Accordingly, the control unit (170) can automatically control to increase the sensitivity (or speed) of the second pointer (207) to the movement of the remote control device (200) when the first pointer (205) is switched to the second pointer (207) directly or via the third pointer (209), and to decrease the sensitivity (or speed) of the first pointer (205) to the movement of the mouse (300) when the second pointer (207) is switched to the first pointer (205) directly or via the third pointer (209).

[0268] Meanwhile, an interface related to the first pointer (205) (or mouse (300)) or the second pointer (207) (or remote control device (200)) may be displayed when the first pointer (205) or the second pointer (207) is displayed, either together with or separately from automatically adjusting the sensitivity of the pointer. This will be further described with reference to FIG. 13. FIG. 13 is an example of a pointer displayed on a video display device according to one aspect of the present disclosure.

[0269] When the first pointer (205) is switched to the second pointer (207) directly or via the third pointer (209) and displayed, the control unit (170) can control the first interface (630) related to the second pointer (207) (or remote control device (200)) to be displayed together, as shown in (13-1) of FIG. 13.

[0270] The first interface (630) may include a sensitivity adjustment menu (634) for adjusting the sensitivity of the second pointer (207) to the movement of the remote control device (200). The user may adjust the sensitivity of the second pointer (207) to the movement of the remote control device (200) by operating the second pointer (207) and the remote control device (200) with respect to the sensitivity adjustment menu (634).

[0271] The first interface (630) may include at least one app icon (631, 632) for at least one app that the user frequently runs when using the remote control device (200). The user can immediately run the app by selecting the desired app icon by manipulating the second pointer (207) and the remote control device (200).

[0272] The first interface (630) may include a settings menu icon (633) of the video display device (100). The user can directly enter the settings menu of the video display device (100) by selecting the settings menu icon (633) by operating the second pointer (207) and the remote control device (200).

[0273] Meanwhile, when the second pointer (207) is displayed by switching to the first pointer (205) directly or via the third pointer (209), the control unit (170) can control the display of the second interface (640) related to the first pointer (205) (or mouse (300)) together, as shown in (13-2) of FIG. 13.

[0274] The second interface (640) may include a sensitivity adjustment menu (644) for adjusting the sensitivity of the first pointer (205) to the movement of the mouse (300). The user may adjust the sensitivity of the first pointer (205) to the movement of the mouse (300) by manipulating the first pointer (205) and the mouse (300) with respect to the sensitivity adjustment menu (644).

[0275] The second interface (640) may include at least one menu icon (641, 642, 643) that the user frequently executes when using the mouse (300). The user may directly execute the corresponding menu by selecting the desired menu icon by operating the first pointer (205) and the mouse (300). In Fig. 13 (13-2), a home menu icon (641), an external input menu icon (642), and a settings menu icon (643) are illustrated as examples. The home menu icon (641) is for entering the home menu or home screen and for entering the menu for selecting the external input of the video display device (100), and the settings menu icon (643) may be for entering the settings menu of the video display device (100).

[0276] Considering that the first interface (530) is displayed when the user attempts to use the remote control device (200), and the second interface (530) is displayed when the user attempts to use the mouse (300), the display size of the first interface (530) may be larger than the size of the second interface (530).

[0277] Meanwhile, when a function (e.g., web browser, etc.) that requires a pointer to be constantly displayed on a video display device (100) is being executed and the video display device (100) switches from a power saving mode (e.g., screen off or dim mode) to a non-power saving mode (e.g., screen on mode), which of the first pointer (205) and the second pointer (207) is displayed first will be further described with reference to FIG. 14. FIG. 14 is an example of a pointer displayed on a video display device according to one aspect of the present disclosure.

[0278] The video display device (100) may be equipped with a user detection sensor (160) (e.g., a camera, etc.) for detecting a user.

[0279] As illustrated in (14-1) of Fig. 14, the control unit (170) can control the first pointer (205) to be displayed by default when the user is detected to be within a reference distance (Dref) from the image display device (100) through the user detection sensor (160) when switching from power saving mode to non-power saving mode. This is in consideration of the fact that when the user is within the reference distance (Dref), the image display device (100) is often controlled using a mouse (300) rather than a remote control device (200).

[0280] Meanwhile, as illustrated in (14-2) of Fig. 14, the control unit (170) can control the second pointer (207) to be displayed by default when the user is detected to be outside the reference distance (Dref) from the image display device (100) through the user detection sensor (160) when switching from the power saving mode to the non-power saving mode. This is in consideration of the fact that when the user is outside the reference distance (Dref), the image display device (100) is often controlled using the remote control device (200) rather than the mouse (300).

[0281] The above describes controlling a video display device using a remote control device and a mouse. Here, the remote control device and mouse are merely examples of input devices for inputting user commands to control the video display device. Therefore, it goes without saying that at least one of the remote control device and the mouse may be replaced with another input device. Examples of other input devices include a wired or wireless joystick, or a smartphone with a video display device remote control app installed.

[0282] Meanwhile, it is also true that the shortcut user interface can be called by inputting a user command to call the shortcut user interface using a remote control device (200) or a mouse (300) even when the first pointer (205) or the second pointer (207) is displayed.

[0283] The above-described present disclosure can be implemented as computer-readable code on a program-recorded medium. The computer-readable medium includes all types of recording devices that store data that can be read by a computer system. Examples of computer-readable media include hard disk drives (HDDs), solid-state disks (SSDs), silicon disk drives (SDDs), ROMs, RAMs, CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, etc., and also includes media implemented in the form of carrier waves (e.g., transmission via the Internet). In addition, the computer may include a control unit (170) of an image display device and a control unit (280) of a remote control device. Therefore, the above detailed description should not be construed as limiting in all respects, but should be considered as illustrative. The scope of the present disclosure should be determined by a reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present disclosure are intended to be included in the scope of the present disclosure.
