Here, for the purpose of explanation, a TV receiver is illustrated as an example of the image display device 100, and a space remote controller is illustrated as an example of the external input device 200.

Referring to FIG. 3, the external input device 200 may transmit and receive signals with the image display device 100 according to an RF communication standard. A control menu may be displayed on the screen of the image display device 100 according to a control signal from the external input device 200. To this end, the external input device 200 may include a plurality of buttons, and may generate an external input signal according to a user's button manipulation. In addition, the external input device 200 may transmit information on the movement of the external input device 200 in the 3D space sensed through the sensing unit to the image display device 100.

In FIG. 3, in response to the user moving or rotating the external input device 200 up/down, left/right, forward/backward, the screen of the image display device 100 indicates the movement of the external input device 200. The corresponding pointer 101 is displayed. The external input device 200 may be referred to as a space remote controller because the pointer 101 is moved and displayed on the screen of the image display device 100 according to the movement in the 3D space.

Information on the movement of the external input device 200 sensed through the sensing unit of the external input device 200 is transmitted to the image display device 100. Then, the image display device 100 may calculate the X and Y coordinates of the corresponding pointer from information about the movement of the external input device 200.

Meanwhile, when a specific button provided in the external input device 200 is pressed, recognition of the up/down and left/right movements of the external input device 200 may be excluded. That is, when the external input device 200 moves away from or approaches the screen of the image display device 100, up, down, left, and right movements are not recognized, and only forward/backward movements may be recognized.

In addition, the moving speed of the pointer 101 displayed on the screen of the image display device 100, the moving direction, and the screen scrolling speed according to the movement may be determined according to the moving speed and/or moving direction of the external input device 200. have. Here, the pointer 101 may be formed of various objects in addition to the arrow shape shown in FIG. 3, for example, a point, a cursor, a prompt, an outline, and the like.

The video display device 100 according to the embodiment of the present invention described above may start recording the video based on a user input while the video is being output on the display unit 170. In addition, when a scroll signal is received from the external input device 200 while the video is continuously being output, browsing for the recorded video is performed.

At this time, the screen corresponding to browsing may be displayed in a manner in which the recorded video is played from the beginning (in this case, the playback speed may be adjusted) or in a manner in which a plurality of still images (eg, thumbnails) are unfolded. . As the scroll signal is received as described above, the output of the recorded previous video or corresponding thumbnails may be referred to as entering the'browsing mode' hereinafter.

In this way, when a preset input is received while the video recorded according to the scroll signal is being browsed, the control unit 150 of the image display device 100 captures the browsing screen being output at the time when the second input is received. Accordingly, the user can easily browse without missing a desired specific scene or a part of a specific scene in the video that has been output from the display unit 170.

Hereinafter, a method of operating an image display device for browsing a desired scene in a video according to an embodiment of the present invention will be described in more detail with reference to FIG. 4.

First, as illustrated in FIG. 4, at least one moving image may be output on the display unit 170 of the image display apparatus 100 (S410 ). In this case, there is no limit to the video output on the display unit 170. For example, the video may include an image of a broadcast program, a plurality of channel browsers, a screen corresponding to execution of an application, a playback screen of a recorded or stored image, and the like.

When a preset first input is received while the video is being output to the display unit 170, the control unit 150 of the video display device 100 starts recording the video output to the display unit 170 (S420). ). To this end, the image display device 100 may further include a recording unit in the control unit 150 or separately from the control unit 150.

Here, the first input is a preset user gesture (eg, preset user motion, eye blinking, voice command, etc.), a push input for a specific key provided in the external input device 200, or a combination of at least one of them. May include, and can be implemented in any other way as long as the input time is relatively small. For example, when a voice command'recording' is input through the external input device 200 or a microphone provided in the image display device 100, the controller 150 may start recording a video.

In this case, in order to more accurately determine the recording time of the video, the control unit 150 pre-stores the video still cut corresponding to the time point at which the first input is received in the storage unit 160, and determines the time point corresponding to the stored still cut. It can be determined as the start time of recording. Accordingly, the user's desired recording start time and the actual recording start time may be matched.

The controller 150 may control the display unit 170 to continuously output an existing video and to perform a video recording function in the background. However, so that the user can recognize that the video recording function is being executed, the control unit 150 outputs feedback (eg, sound, guide voice, message, etc.) at the start of recording or when the recording function is executed. The corresponding image may be output on an area of the display unit 170.

As described above, when a scroll signal is received from the external input device 200 while the video recording function is being executed (S430), the controller 150 may perform browsing on the recorded video (S440). ). Accordingly, a recorded video (ie, a video previously output to the display 170) may be output on at least one area of the display unit 170 or a plurality of thumbnails corresponding to the recorded video may be output.

Here, the scroll signal may be generated through an input applied to a wheel key or a direction key provided in the external input device 200. Specifically, when a scroll signal is generated using the wheel key, the recorded video may be browsed back and forth as the provided wheel key is rotated up/down. In addition, when a scroll signal is generated using a direction key, the recorded video may be browsed back and forth by pushing the provided right direction key and the left direction key.

The control unit 150 may change a screen corresponding to browsing according to the direction and speed of the scroll signal received from the external input device 200. Specifically, when a scroll signal is first received from the external input device 200, the recorded screen is recorded. The first scene of the video is displayed, and fast forward/reverse of the recorded image is performed according to the direction of the scroll signal subsequently received from the external input device 200.

In addition, when a scroll signal is received while the video is being recorded, the controller 150 may stop recording the video. In this case, video recording ends when the scroll signal is first received. In this case, the control unit 150 may pop up a message asking whether to stop recording the video on a region of the display unit 170 and terminate the recording of the video based on a response to the pop-up message.

When a second input is received while browsing the recorded video as described above, the control unit 150 captures a browsing screen corresponding to a time point at which the second input is received (S450).

Here, the second input is a control command for capturing a screen corresponding to browsing, and is among a gesture input different from the first input, a voice input, or an input for a specific key provided in the external input device 200. There may be at least one. When the second input is received as described above, the control unit 150 may recognize that a control command for capturing a browsing screen output to the display unit 170 is input.

Next, the control unit 150 may store the captured browsing screen in the storage unit 160. In this case, ACR information, time information, program information, related content information, etc. included in the captured browsing screen are also stored in the storage unit 160. In addition, the browsing screen stored in this way is continuously stored differently from other recorded videos even when browsing is terminated.

The captured browsing screen may be output on the entire area of the display unit 170, and the captured browsing screen may include ACR information, person information, related content information, link information, and the like. According to the selection of any one of ACR information, person information, related content information, or a region in which link information is output included in the captured browsing screen, the control unit 150 provides additional related functions (e.g., editing function, related information search function). Etc.), and the execution result may be displayed in one area of the display unit 170. At this time, when the user selects a specific key provided in the external input device 200, for example, the'Exit' button, the browsing screen is displayed again on the display unit 170 or the previously output video screen is continuously displayed. I can.

As described above, according to the operating method of the video display device according to the embodiment of the present invention, the desired scene is recorded by recording the range that the user wants to browse in the video being output, and scrolling the recorded video using an external input device. It is possible to easily browse for or information and capture the scenes you want to perform additional functions on.

Hereinafter, in connection with the above-described step (S420), a method of starting or ending recording of a video output to the display unit 170 will be described in detail.

As described above, the image display device 100 according to an embodiment of the present invention receives a preset input (eg, preset user gesture and/or key input), Start recording.

When a video recording starts as a preset input is received as described above, the controller 150 may output a feedback indicating the start of recording. In this case, the feedback may be output in the form of at least one of sound, text, and image. For example, when recording starts as a user performs a specific gesture (eg, a hand gesture indicating'o'),'recording starts' through the audio output unit 180 of the video display device 100 Voice feedback such as' may be output. In addition, while the recording function is being performed, an image object (eg, a recording display icon) indicating that recording is being performed may be continuously displayed on at least a part of the current video screen output to the display unit 170. The video from the start of recording to the end of recording is stored in the storage unit 160.

Meanwhile, when a scroll signal is received through the external input device 200 during recording, a browsing mode is entered, and a browsing screen for the recorded image is output on the display unit 170.

In this case, when a scroll signal is received, the controller 150 may end recording of the video and then enter a browsing mode of the recorded video. That is, the controller 150 recognizes the first scroll signal received through the external input device 200 as a recording end signal and a first control signal for entering the browsing mode, and the subsequent scroll signal changes the browsing screen. It can be recognized as a second control signal for.

As the first control signal is generated, an audio signal indicating the end of recording may be output to the audio output unit 180 of the image display device 100. In addition, a browsing area corresponding to the entry of the browsing mode may be displayed on at least a part of the display unit 170. In this case, the browsing area may overlap at least a part of the video screen that has been output on the display unit 170, and may be output smaller than the area in which the video screen is output so that the user can maintain viewing of the existing screen. In addition, the first browsing screen displayed in the browsing area may be the first still cut of the recorded video or a thumbnail thereof.

Subsequently, when the second control signal is received, the control unit 150 may change the browsing screen displayed in the browsing area. For example, as the wheel key provided in the external input device 200 is scrolled from top (top) to bottom (bottom), the browsing screen may move forward in units of a predetermined section. In addition, for example, as the right arrow key provided in the external input device 200 is pushed, the browsing screen may move forward in units of a predetermined section. When browsing is performed up to the last scene of the recorded video, the control unit 150 may release the browsing mode and control the browsing area to disappear from the display unit 170.

Meanwhile, in another example, even when a scroll signal is received, the controller 150 may enter the browsing mode without stopping the recording. In this case, in the browsing mode state, since the video that has been output to the display unit 170 is continuously recorded, the browsing mode continues until there is a separate input signal. In this case, the control unit 150 is a browsing mode only when a specific key (eg,'exit' button) provided in the external input device 200 is pushed or a preset voice command (eg,'release') is input. Is released, and the browsing area may be controlled to disappear from the display unit 170.

Hereinafter, with reference to FIG. 6, a method of performing browsing based on a recorded video in an image display device according to an embodiment of the present invention will be described in more detail.

Regarding the steps S430 and S440 described above with reference to FIG. 4, when a scroll signal is received from the external input device 200 during video recording, the control unit 150 of the image display device 100 records during that time. Browsing the downloaded video.

In this case, the controller 150 may determine a browsing direction and a browsing speed of the recorded video based on a scroll direction and speed corresponding to a scroll signal received from the external input device 200.

Specifically, when a scroll signal directed from the top to the bottom is input according to the operation of the wheel key provided in the external input device 200, the control unit 150 fast-forward the browsing screen of the recorded video or its thumbnail. You can do it. At this time, the faster the moving speed of the wheel key, the faster the browsing screen of the recorded video or its thumbnail is flipped forward, and the control unit 150 automatically automatically when the scroll speed corresponding to the operation of the wheel key exceeds the reference value. It is possible to control to move to the last scene of the recorded video or add scrolling to which acceleration (eg, acceleration in units of a constant value) is added.

The controller 150 performs scrolling to which acceleration is added as described above, and when a predetermined brake signal (eg, a push input for a specific key or a predetermined voice command, etc.) is received through the external input device 200, the scrolling is immediately performed. It is possible to control so that a browsing screen corresponding to the paused time point is output to one area of the display unit 170, for example, a browsing area. Here, the browsing area according to the entering of the browsing mode may be an area of the display unit 170 as described above, or may be the entire display unit 170 as shown in FIG. 6.

Specifically, for example, as shown in FIG. 6, when a scroll signal is received from the external input device 200, a browsing mode is entered, and a video screen output to the display unit 170 corresponds to a recorded video. The browsing screen 610 may be switched to. In this case, an icon 611 indicating that the recorded video is being output may be displayed in an area of the display unit 170, for example, in the upper right. In addition, although not shown, information on the location or time of the browsing screen currently output on the display unit 170 together with the icon 611 (eg, for the first scene of a video recorded for 15 minutes and 15 seconds) 00: 01/15:15) may be output.

While browsing is performed as described above, the control unit 150 can execute an additional function related to information included in the browsing screen 612 output to the display unit 170 using the external input device 200. have.

For example, when the next program information is displayed in the lower area on the browsing screen 610, when the corresponding area is pointed using the external input device 200, that is, a pointer that moves according to the movement of the external input device 200 When is brought to the corresponding area, a menu window 613 displaying executable functions (eg, reservation, previous broadcast view, more related programs, etc.) in relation to the next program information is displayed on one area of the display unit 170. I can. If the browsing screen 610 was being output in a video format, playback of the browsing screen 610 may be suspended.

In this case, when a specific function (eg, reservation) is selected by moving the pointer to the menu window 613 using the external input device 200, the selected function is immediately executed and the browsing mode is canceled. On the other hand, when a scroll signal is received again from the external input device 200 without selecting a specific function, the displayed menu window 613 disappears, and the next browsing screen 620 is subsequently output.

When the displayed next browsing screen 620 is the last scene of the recorded video, the browsing mode is canceled, and the video screen 630 (eg, a specific broadcast program) that was originally being output is displayed on the display unit 170 again. . In this case, the displayed icon 611 may disappear so that the user can recognize the cancellation of the browsing mode.

When browsing for the recorded video is completed, the controller 150 controls to store the captured browsing screen in the storage unit 160 and delete the other recorded video if there is a captured browsing screen. On the other hand, when there is no captured browsing screen, the controller 150 deletes the entire recorded video.

In addition, although not shown, if an input for starting recording ('first input') is received again while the video screen 630 is being output, the controller 150 is configured to display the next recorded video following the captured browsing screen. Can be pasted together. In this case, when entering the browsing mode, the browsing screen captured from the previously recorded video is displayed as the first browsing screen. In addition, in another example, the browsing mode is released while browsing for a previously recorded video is not completed, and an input for starting recording ('first input') is received again while the video screen 630 is output. If so, the control unit 150 may concatenate the next recorded video following the last scene of the previously recorded video.

On the other hand, in another example, when the recording of the video output to the display unit 170 is started as the first input is received, the browsing of the recorded video is performed by an external terminal interlocked with the video display device. The image data corresponding to the recorded video may be transmitted to the interlocked external terminal to be performed in This is to prevent the user from disturbing viewing as browsing is performed in the image display device 100.

To this end, the control unit 150 may preset at least one external terminal (eg, a computer, a mobile phone, a tablet, etc.) interlocked with the image display device 100. In addition, when the first input is received, the controller 150 may transmit a control signal to output a message window asking whether to download the recorded video on the display of the interlocked external terminal. Further, the controller 150 may determine whether to transmit the recorded video based on a response signal to the message window.

Hereinafter, FIGS. 5A to 5C show various examples of outputting a browsing screen based on a recorded image.

Referring to FIG. 4, in relation to the above-described step (S440), while browsing the recorded video, the control unit 150 of the video display unit 100 displays a video recorded on at least one area of the display unit 170. A corresponding browsing screen can be displayed.

In this case, the browsing screen may be a playback screen of a recorded video or a thumbnail generated based on a representative frame of a specific section in the recorded video.

When the browsing screen is a method of playing the recorded video as it is, for example, a browsing screen in a manner that overlaps at least a part of the currently output video screen 501 of the display unit 170 as shown in FIG. 5B. 530 may be displayed. It goes without saying that the location or shape of the browsing area on which the browsing screen is output is not limited to the rectangular area and the lower right corner as shown in FIG. 5B, and may be output in a different shape or location. In addition, an icon 531 indicating that the image is a recorded image may be displayed in the browsing area. Alternatively, the boundary area of the browsing area may be displayed in a predetermined thickness so that the browsing area can be clearly distinguished visually, or may be displayed to have a highlighting effect such as flickering.

In this way, while the browsing screen is being output on at least one area of the display unit 170, the second input ('signal for screen capture') is not received for a preset time or the recorded video is not browsed. Upon completion (ie, when the last scene of the recorded video is reached), the controller 150 may control the browsing screen corresponding to the recorded video to disappear from the display unit 150. As a result, the browsing mode is canceled, and the moving picture screen 502 that was originally output on the display unit 170 is subsequently output as shown in the lower part of FIG. 5C.

On the other hand, in the case of a thumbnail generated based on a representative frame of a specific section in the recorded video, a scroll signal is displayed in the lower area of the video screen 501 currently being output of the display unit 170 as shown in FIG. 5A. The thumbnail 510 corresponding to the browsing screen according to may be output as a still image. Accordingly, screen blocking of the moving picture screen that has been output to the display unit 170 can be minimized.

At this time, since not all frames of the recorded video are generated as thumbnails, when the output thumbnail 510 is selected, the selected thumbnail is captured and the recorded video is played from the browsing screen corresponding to the selected thumbnail. Can be.

In addition, the controller 150 may output a list including a plurality of thumbnails in a region of the display unit along a scroll direction of a scroll signal received from the external input device 200. In this case, as shown in FIG. 5A, a plurality of thumbnails rather than one thumbnail are output on the lower area of the display unit 170.

In addition, as shown in FIG. 5A, the thumbnail may be output together with a progress bar 520 indicating the location and time information (17:36 seconds) of the scene corresponding to the output thumbnail. In this case, by moving the pointer 101 according to the movement of the external input device 200 in the progress bar 520, the thumbnail corresponding to the browsing screen can be changed back and forth. Accordingly, a desired browsing screen can be searched, and a desired scene can be captured by selecting a thumbnail using a pointer.

Meanwhile, in another example, as illustrated in FIG. 5C, the browsing area 540 may be the entire area of the display unit 170. In this case, when browsing is finished, the video screen 502 that was originally being displayed may be limited to be displayed.

Hereinafter, an example of a method of utilizing a captured browsing screen will be described in detail with reference to FIG. 7.

Regarding the above-described step (S440), while browsing from the external input device 200 is performed, the playback speed of the recorded video or the playback speed of the browsing screen corresponding to the selected thumbnail is slower than the original output speed of the recorded video or Or it can be adjusted to be slow (eg, by repeatedly operating the wheel key up and down and up and down a predetermined number of times).

Alternatively, as shown in FIG. 7, in proportion to the direction and degree of scrolling of the scroll signal received from the external input device 200, the controller 170 You can control it to unfold. As a result, the control unit 150 may output the list 720 including a plurality of thumbnails along the scroll direction of the received scroll signal to one area of the display unit 170, for example, a lower area. In this case, the number of thumbnails included in the list 720 corresponds to scrolling. Four thumbnails (721, 722, 723, 724) browsed by rotating a wheel key provided in the external input device 200 from top to bottom by half a turn are displayed from left to right in the lower area of the display unit 170. In the unfolded state, when the wheel key is further rotated in the same direction, the next thumbnails 725, 726, and 727 are subsequently output and further included in the list 720. On the other hand, when the wheel key is rotated in the opposite direction while the list 720 is displayed, the output thumbnails 721, 722, 723, and 724 may disappear or only a portion (eg, 721, 722) may remain.

At this time, if the desired scene that the user wants to capture is the thumbnail 725 in the third from the left, when the corresponding thumbnail is selected using the pointer 101, the browsing screen 731 corresponding to the selected thumbnail 725 is displayed. It is captured and outputted to the entire area of the display unit 170. In this case, the selection of the thumbnail corresponds to the second input.

In this way, when a second input is received according to the selection of a thumbnail, the control unit 150 includes a browsing screen corresponding to a time point at which the second input is received, ACR information, time information, program information, and Content information related to the program information may be stored in the storage unit 160 of the image display device 100.

In addition, a menu window 732 including an additionally executable function may be displayed in an area of the captured browsing screen 730. The menu window 732 may be immediately output when the captured browsing screen 730 is displayed, or when the pointer 101 enters a specific area, for example, the lower right area. When a specific function (eg, person) is selected in the menu window 732, an additional search function related to person information included in the captured browsing screen 730 may be executed. As a result, as shown in FIG. 7, a menu area 733 for executing an additional search function related to the person (eg, viewing photos, viewing programs, etc.) is output on one area of the display unit 170. I can. In this case, a display indicating a selection, for example, a shading effect, may be output in an area related to the selected person information.

In addition, in another example, when content information related to program information is included in the captured browsing screen, the controller 150 may output a corresponding web page screen to one area of the display unit in response to the content information being selected. have. For example, when view photo is selected in the menu area 733, a web browser is automatically executed and searched, and pictures related to the selected person information may be output to the menu area 733.

As described above, according to the video display device and the method of operating the video display device according to the present invention, after recording the range that the user wants to browse from the video being output, the recorded video is scrolled by using an external input device. You can replay the desired scene or information in the video, not the video. Accordingly, there is an advantage that the user can easily and accurately browse the video by capturing the scene for which additional information is to be obtained on the browsing screen in an instant. In addition, by implementing a recorded video or browsing screen to cover only a part of the currently output screen or allowing the user to browse the recorded video later, You can browse scenes or information.

Further, those of ordinary skill in the art to which the present invention pertains will appreciate that the present invention can be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not limiting. The scope of the present invention is indicated by the scope of the claims to be described later rather than the detailed description, and all changes or modified forms derived from the meaning and scope of the claims and their equivalent concepts are included in the scope of the present invention.
