  The display apparatus 100 displays a combination of a plurality of different contents, and each of the plurality of glasses apparatuses 200-1 and 200-2 transmits only one content image displayed on the display apparatus 100. Displaying a combination of contents means that the contents are mixed to form and display a video frame, or the contents are alternately displayed. Here, displaying a plurality of contents alternately means that a frame including video information related to one content is displayed first, and then a frame including video information related to another content is displayed alternately. This means that a frame containing video information related to different contents is displayed.

  FIG. 1 is a diagram illustrating a method for providing a plurality of 2D contents according to an exemplary embodiment of the present invention.

Both the shutter glass and the right shutter glass can be operated to open. Thus, the first viewer viewer1 wearing the first glasses device 200-1 is one content A synchronized with the first glasses device 200-1 among the plurality of contents A and B displayed alternately. Can only watch. The second viewer viewer2 wearing the second glasses device 200-2 in the same manner can view only the content B. The alternate display of video frames for different content is done at a very fast rate, and the afterimage effect of the retina persists while the lens is closed, so that the user will see a natural video.

  FIG. 2 is a diagram illustrating a method for providing a plurality of 3D contents according to an exemplary embodiment of the present invention.

  As shown in FIG. 2, when a plurality of 3D contents (contents A and B) are 3D contents, the display device 100 displays each of the 3D contents while alternately displaying the plurality of 3D contents (contents A and B). The left eye image and the right eye image can also be displayed alternately.

  For example, the left eye image AL and the right eye image AR of the 3D content A can be displayed, and the left eye image BL and the right eye image BR of the 3D content B can be displayed alternately. In this case, the first glasses device 200-1 opens the left eye and the right eye glass at the time of display of the left eye image AL and the right eye image AR of the 3D content A, and the second glasses device 200-2 performs the 3D content.

  However, this is an explanation for a case where a shutter glass method is assumed. In the case of the polarization method, the polarization direction of each of the plurality of content images matches the polarization direction of the first glasses device and the second glasses device. It should be obvious to those skilled in the art that the multi-view mode can be implemented.

  3 and 4 are diagrams for explaining a method of transmitting a synchronization signal according to various exemplary embodiments of the present invention.

  Referring to FIG. 3, the display apparatus 100 can broadcast or multicast one signal obtained by multiplexing the synchronization signals corresponding to the first glasses apparatus 200-1 and the second glasses apparatus 200-2. The devices 200-1 and 200-2 are synchronized with a synchronization signal corresponding to a user command (for example, a channel switching command) among the corresponding signals, and can operate to turn on / off the shutter glass.

  However, the above-described embodiment is merely an example, and as illustrated in FIG. 4, the display apparatus 100 corresponds to each of the synchronization signals corresponding to the first glasses apparatus 200-1 and the second glasses apparatus 200-2. A form in which the glasses apparatus 200-1 and 200-2 are unicast to the glasses apparatus 200-1 and 200-2 and the corresponding glasses apparatus 200-1 and 200-2 receives the synchronization signal may be realized.

Alternatively, in the case of an embodiment in which content is received from the various recording medium playback devices described above, a plurality of receiving units 110-1, 110-2,. . . 110-n can be implemented by an interface unit (not shown) connected to the recording medium playback apparatus. For example, it can be realized by an AV terminal, a COMP terminal, an HDMI terminal, or the like.

  In this way, the plurality of receiving units 110-1, 110-2,. . . 110-n may be embodied in various forms according to the embodiment.

  In addition, a plurality of receiving units 110-1, 110-2,. . . 110-n do not necessarily receive content from the same type of source, but can also receive content from different types of sources.

  A plurality of signal processing units 130-1, 130-2,. . . , 130-n are a plurality of receiving units 110-1, 110-2,. . . , 110-n, various signal processing can be performed on each of the received contents.

  Meanwhile, according to various embodiments of the present invention, the display apparatus 100 may further include a multiplexing unit (not shown) that multiplexes video frames. The multiplexing unit 170 includes a video frame of the first content, a video frame of the second content,. . . , The video frames can be multiplexed and output so that at least one video frame of the nth content is alternately arranged.

  The output unit 130 displays a plurality of contents according to data output from a multiplex unit (not shown). Accordingly, the output unit 130 can display in a form in which at least one video frame of each content is alternately arranged.

  The output unit 130 performs a function of outputting one content view in the single view mode (first mode) and outputting a plurality of content views in combination in the multi view mode (second mode).

  Here, the output unit 130 includes a liquid crystal display panel (Liquid CrystAl DisplAy Panel), a plasma display panel (PlAsmA DisplAy Panel E), an OLED (OrgAnic Light is Ami D eFuD eFl eD e), a VFD (Vacuum eFuD eFuD eF iD eF iD e F e) (Electro Luminescence Display Ay) or the like.

  As described above, a mode in which video frames of respective contents are alternately arranged and displayed can be named as a multi-view mode (or a second mode or a dual view mode). When the display device 100 operates in a general mode (or a single view mode (first mode)) for displaying only one of 2D content or 3D content, the plurality of receiving units 110-1, 110-2,. . . , 110-n, only one of them can be activated to process the content. If the user selects the multi-view mode (second mode) while operating in the general mode, the display apparatus 100 can process the data by the above-described method by activating the remaining receiving units.

  On the other hand, the content described above can be 2D content and can be 3D content. The 3D content means content that allows a user to feel a three-dimensional effect by using multi-view images that represent the same object (oObject) from different viewpoints.

  When using a plurality of 3D contents, the output unit 130 includes a plurality of frame rate conversion units 122-1, 122-2,. . . , 122-n, the left-eye video and the right-eye video included in each 3D content can be multiplexed in a preset arrangement form and alternately arranged with video frames of other contents.

  Thereby, the left eye video of the first content, the right eye video, the left eye video of the second content, the right eye video,. . . The left eye video and the right eye video of the nth content are sequentially arranged and displayed, and the user recognizes the left eye video and the right eye video of one content via the glasses device 200.

  On the other hand, the display apparatus 100 further includes a configuration for providing audio data included in each content differently for each user when operating in the multi-view mode (second mode). That is, each receiving unit 110-1, 110-2,. . . 110-n, a demultiplexer (not shown) for separating video data and audio data from the content received, an audio decoder (not shown) for decoding the separated audio data, and each decoded audio data May be further provided with a modulation unit (not shown) that modulates the signals into different frequency signals, an output unit (not shown) that transmits each modulated audio data to the glasses apparatus, and the like. Each audio data output from the output unit 130 is provided to the user via an output unit such as an earphone provided in the eyeglass device. Such a configuration is not shown separately because it is not directly related to the present invention.

  On the other hand, if the content includes additional information such as EPG (Electronic Program Am Guide) and subtitles, the demultiplexer can further separate the additional data from the content. The display apparatus 100 can also add subtitles and the like processed so as to be displayed via an additional data processing unit (not shown) to the corresponding video frame.

  The synchronization signal generation unit 140 generates a synchronization signal for synchronizing the glasses apparatus corresponding to each content according to the display timing of each content. That is, the synchronization signal generation unit 140 generates a synchronization signal for synchronizing the glasses apparatus with the display timing of the video frame for the content in the multi-view mode (second mode).

  The interface unit 150 transmits a synchronization signal to the glasses apparatus. In this case, the interface unit 150 can transmit the synchronization signal to the glasses apparatus by various methods.

Here, the reference time point is a time point when a vertical synchronization signal is generated in a video frame of each content, and time information for the time point when the vertical synchronization signal is generated can also be included in the transmission stream.

  In order to perform communication according to the Bluetooth communication method, the interface unit 150 performs pairing (pAiring) with each eyeglass device. When pairing is completed, information about each eyeglass device, for example, a device ID (or address) or the like can be registered in the interface unit 150. The interface unit 150 matches the display timing of each content with information for the eyeglass device, and generates one transmission stream according to the Bluetooth communication standard. For example, the interface unit 150 can match information for different glasses devices for each content according to the order in which the video frames of the content are arranged. That is, when two contents are alternately provided in the multi-view mode (second mode), the first, third,. . . , The nth video frame of the content matches the information for the first glasses device, and the second, fourth,. . . The video frame of the content arranged in the (n + 1) th can match information for the second glasses device (where n is an odd number).

A signal can be transmitted to the eyeglass device. The glasses apparatus may be embodied such that the shutter glass is turned on during a first period that is a high level and the shutter glass is turned off during a second period that is a low level. In addition, the synchronization signal can be generated by various methods.

  The frame rate conversion unit 122-1 converts the content frame rate provided from the video processing unit 121-1 to match the multi-content display rate with reference to the output rate of the display apparatus 100. Specifically, if the display apparatus 100 operates at 60 Hz, the frame rate conversion unit 122-1 can convert the frame rate of each content to n × 60 Hz.

  Since the reception unit 110, the signal processing unit 120, the multiplexing unit, the output unit 130, the control unit 160, the interface unit 150, and the synchronization signal generation unit 140 have been described above, redundant description will be omitted, and the following description will be given for the present embodiment. Functions of the imaging unit 120, the storage unit 180, and the control unit 160 will be described.

  The imaging unit 120 functions to perform imaging.

  Here, the image capturing unit 120 may be embodied by a general camera, but may be embodied by a form including at least one of a depth camera and a color camera. Here, the depth camera recognizes the distance to the user and the remote control device, user motion, and the like, and the color camera can recognize the user's face and hand movement. On the other hand, the depth camera can be embodied to correct the imaging screen according to the depth, that is, the distance from the camera, and the correction mode can be enlarged / reduced of the screen, resolution adjustment, etc. Can take the form.

  On the other hand, in the illustrated embodiment, the imaging unit 120 has been described as a built-in camera provided inside the display device 100. However, this is only an embodiment, and the imaging device 10 is separately provided outside the display device 100. It can also be embodied by an external camera provided.

  However, for convenience of explanation, the following description will be made assuming that the imaging device 10 is provided separately from the display device 100.

  At this time, the control unit 160 detects the variation state of the user who views the display device 100 using the data captured by the imaging unit 170, and determines the single view mode (first mode) or the user according to the variation state of the user. The output unit 130 can be controlled to operate in the multi-view mode (second mode).

  Specifically, the control unit 160 analyzes the data captured by the imaging unit 170 to determine whether the user has left the imaging target space, whether the user has been added, and whether the added user has previously left the user. Can be detected.

  Accordingly, when the addition of a user is detected in a state where the output unit 130 operates in the single view mode (first mode), the control unit 160 switches to the multi view mode (second mode). Can be controlled.

  In addition, the control unit 160 may switch the output unit 120 to switch to the single view mode (first mode) when the output unit 130 is detected to operate in the multi-view mode (second mode). Can be controlled.

  The storage unit 180 is a storage medium in which various programs necessary for operating the display apparatus 100 are stored, and can be embodied by a memory, an HDD (HAard Disk Drive), or the like. For example, the storage unit 180 can store a program for performing the operation of the control unit 160, and temporarily stores data according to the performance of the control unit 180 or stores various reference data. Can do.

  On the other hand, the control unit 160 switches the output unit 130 so as to switch to the single view mode (first mode) when the separation of the user is detected in a state where the output unit 130 operates in the multi-view mode (second mode). When controlled, the corresponding content view environment information can be stored in the storage unit 180 at the same time.

  Further, when the disconnected user returns, the control unit 160 reconfigures the content view corresponding to the disconnected user using the viewing environment information of the content view stored in the storage unit 180, and reconfigures the content view The output unit 130 can be controlled to output a plurality of content views including In this case, the control unit 160 detects whether the newly added user is a user who has left before through the video imaged through the imaging unit 170, and determines whether the previous user has returned. it can.

  On the other hand, in order to detect whether or not the user who has left has returned, face recognition technology can be applied to the captured video. The face recognition technology is a technology for constructing a database of existing face photos and confirming and recognizing whether or not they are the same as existing face photos by comparing them with images taken by a camera. The face recognition technology can be basically performed through the process of two steps of face detection and face recognition. In the case of face detection, a knowledge-based method (knowledge-Based Methods), a feature-based method (FeAture-Based Methods), a template matching method (Template-mAching Methods), etc. can be used. In the case of face recognition, a 2D algorithm is used. A 3D algorithm or the like can be used. Since the face recognition technique is a widely known technique, a detailed description thereof will be omitted.

  On the other hand, the viewing environment information of the content view includes content type (or channel number), volume, screen mode, backlight (BAcklight), luminance (Brightness), sharpness (shArpness), black tone (BlAck tone), contrast ( Information such as control, color, color, tint, and subtitle position and size may be included.

  However, the environment information when the content is 2D video and the environment information when the content is 3D video can include slightly different configurations. For example, the environment information in the case of 2D video includes backlight, luminance, sharpness, contrast, color, and tint, and the environment information in the case of 3D video includes depth, focus, and the like. Can further be included. In addition, the environment information may include equalizer (equalizer) information (balance, amplification level for each frequency band), SRS TruSurround HD, volume information, and the like.

  On the other hand, the storage unit 180 can store viewing environment information of content views individually set for each user.

  In this case, when the addition of a new user is detected through the video imaged by the imaging unit 170, the control unit 160 selects the content view corresponding to the new user from the viewing environment information stored in the storage unit 180. The output unit 130 can be controlled to configure a new content view using the viewing environment information and output a plurality of content views including the new content view.

  In addition, the control unit 160 can set the display mode in the public mode or the private mode according to a user command transmitted from the glasses device (not shown). However, the present invention is not limited to this, and the corresponding user command can be transmitted from a remote control device (not shown) such as a remote controller.

  Specifically, when the public mode is set, the controller 160 switches between the multi-view mode (second mode) and the single view mode (first mode) according to the user's variation state. Can do. That is, in the public mode, the change of the content view can be freely allowed.

  In addition, when the private mode is set, the control unit 160 prohibits switching between the multi-view mode (second mode) and the single-view mode (first mode) even when the user's fluctuation state is detected, It can be controlled to operate in a fixed mode (second mode). For example, in the private mode, even if the addition of a user is detected in the single view mode (first mode) state, the added user is prevented from viewing the corresponding content while maintaining the single view mode (first mode). be able to.

  On the other hand, the private mode and the public mode described above are described in association with the multi-view mode (second mode) and the single-view mode (first mode) according to the user change state, and other embodiments of the present invention. Accordingly, the private mode and the public mode can operate separately from the multi-view mode (second mode) and the single view mode (first mode) according to the user change state.

  In this case, in the private mode, when the specific content view is set to the private mode, even if another viewer's glasses device (not shown) is connected to the display device 100, the corresponding glasses device (not shown). The synchronization signal for the content view set to the private mode can be cut off. This will be described in detail later with reference to the drawings.

  On the other hand, the imaging unit 170 can capture an IR signal output from a remote control device (not shown).

  In this case, when a user command is received from a remote control device (not shown) while operating in the multi-view mode (second mode), the control unit 160 captures an IR signal captured by the imaging unit 170. The user command can be detected from a remote control device (not shown) via the remote control and the received user command can be applied to the content view corresponding to the detected user.

  For example, when using only one remote control in the multi-view state, assuming that a command to synchronize content is not input to the remote control itself, the corresponding remote control signal is displayed on any of the plurality of users on the display device 100 side. Or a user command by a user, and a scenario in which the user command is applied to a corresponding content view can be obtained. In this case, a remote control device (not shown) and a method of detecting a user who inputs a user command by analyzing a video image of the user may be possible.

  On the other hand, in the above-described embodiment, the case where the private mode is set via the glasses device (not shown) has been described. However, the present invention is not limited to this, and the private mode is already set for each content type. It may also be possible. For example, a broadcast restriction screen that prohibits minors from viewing, a screen for executing various game programs, a screen for executing a messenger program, an e-mail confirmation screen, or an SNS screen are preset in the private mode. Can be. Information regarding the content type set in the private mode as described above can be registered in advance in a memory (not shown) in the display apparatus 100 or can be provided from a separate external source.

  In addition, when a new user is added in the single view state and switched to the multi-view mode (second mode), the control unit 160 adds the left eye glass and the right eye glass of the new user's glasses device (not shown). Different content views can be synchronized to select the content view desired by the new user.

  In addition, the control unit 160 can detect a user's operation from the video captured through the imaging unit 170, and can control a plurality of content views according to the detected user's operation.

  For example, the control unit 160 can detect the left hand or the right hand of the user through the captured video, and can control different content views according to the control operation of the left hand or the right hand. For example, the first content view can be controlled when a left hand control operation is detected, and the second content view can be controlled when a right hand control operation is detected.

  Further, the control unit 160 can change the content when the viewer of the content view moves his / her hand horizontally from the left side to the right side (or from the right side to the left side). You may apply.

  Hereinafter, the eyeglass device 200 according to the embodiment that changes a view mode according to a user's variation state will be described.

  FIG. 9 is a block diagram illustrating a configuration of a glasses apparatus 200 according to various embodiments of the present invention.

  The eyeglass device 200 according to the embodiment includes a communication interface unit 210, a control unit 220, a shutter glass driving unit 230, a first shutter glass unit 250, a second shutter glass unit 260, and an input unit 240.

  Since the communication interface unit 210, the shutter glass driving unit 230, the first shutter glass unit 250, and the second shutter glass unit 260 have been described above, only the input unit 240 and the control unit 220 will be described here.

  The input unit 240 can receive various user commands.

  Specifically, the input unit 240 includes a pairing command for performing pairing with the display apparatus 100, a content view switching command, a mode setting command for setting a private or public mode, a 3D mode or a dual view mode setting command. Etc. can be received.

  For example, the input unit 240 can be implemented by at least one of a touch sensor, an operation button, and a slide switch.

  At this time, when the content view conversion command is input, the control unit 220 sequentially switches the first shutter glass unit 250 and the second shutter glass unit 260 according to the synchronization signal received from the display apparatus 100. The shutter glass driving unit 230 can be controlled to be turned on / off.

  In addition, when the private mode or the public mode is selected, the control unit 220 can control to transmit a user command corresponding to the mode to the display apparatus 100. At this time, the transmission stream may include information on a private mode or a public mode according to a user command. In addition, the transmission stream may include information for a 3D mode or a dual view mode according to a user command.

  FIG. 10 is a view for explaining an external configuration of the eyeglass device 200 according to the embodiment of the present invention shown in FIG.

  As shown in FIG. 10, the eyeglass device 200 according to the embodiment of the present invention may include a plurality of input buttons 241, 242, and 243.

  Each of the plurality of input buttons 241, 242, and 243 can receive different user commands.

  For example, each of the plurality of input buttons 241, 242, and 243 includes a pairing command for performing pairing with the display devices 100 and 300, a content view switching command, a mode setting command for setting a private or public mode, and the like. Can receive.

  However, the form of the input button described above is merely an embodiment, and can be implemented by a form such as a touch sensor or a slide switch. In some cases, the form is provided in a menu form via the display devices 100 and 300. Is also possible.

  Hereinafter, a method for implementing a private mode and a public mode according to an embodiment of the present invention will be described.

  11 and 12 are diagrams for explaining a method for implementing the private mode and the public mode according to an embodiment of the present invention.

  As shown in FIG. 11, when the public mode is set for the specific content, the corresponding content can be viewed by other user viewers 2. That is, the synchronization signal of the corresponding content can be transmitted not only to the glasses device 200-1 worn by the viewer 1, but also to the glasses device 200-2 worn by the viewer 2.

  However, as shown in FIG. 12, when the private mode is set for the specific content, the other user viewer2 cannot view the corresponding content, and the other user viewer2 has a basic channel or a new channel. A UI for selection can be provided. That is, the synchronization signal of the corresponding content can be embodied so as to be blocked by the glasses device 200-2 worn by another user viewer2.

  FIGS. 13 and 14 are diagrams showing examples of user interface screens related to the mode setting shown in FIGS. 11 and 12.

  When a mode setting command is input via the glasses device 200-1 of the user viewer 1 who views the specific content, the mode change is confirmed on the screen (display unit) of the display device 100 as shown in FIGS. A UI screen can be displayed. However, this is merely an embodiment, and the mode can be instantly changed according to the mode setting command input without displaying the corresponding UI.

  15 and 16 are diagrams for explaining a method of using a captured image according to still another embodiment of the present invention.

  As shown in FIG. 15, when a plurality of users viewer 1 and viewer 2 use one remote control device 300 in the multi-view mode (second mode), the remote control device uses an image captured through the camera 10. It can be detected by which user the remote control signal transmitted from 300 is transmitted.

  Alternatively, it is possible to detect an IR signal output from the remote control device 300 through an image captured through the camera 10 and detect which user has transmitted the corresponding remote control signal. In this case, the remote control device 300 can be embodied to transmit a part of the remote control signal such as the device ID signal via the IR signal even when using the RF communication.

  As shown in FIG. 16, even when a plurality of users use separate remote control devices 300-1 and 300-2 in the multi-view mode (second mode) state, the remote control devices 300-1 and 300- Unless 2 is paired with a specific content, it is not known by which user the transmitted remote control signal is transmitted, so it is determined by which user the corresponding remote control signal is transmitted in the same manner as in FIG. It can be detected.

  FIG. 17 is a view for explaining a multi-view switching method according to still another embodiment of the present invention.

  As shown in FIG. 17, when a new user is added in the single view mode (first mode), when the user is switched to the multi-view mode (second mode), at the same time, the new user has a possible content view. At least two or more can be provided. Thereby, the new user can select the content he desires. For example, different content views are provided for the left eye glass and the right eye glass of the new user, and the new user can select the content view he / she desires.

  FIG. 18 is a flowchart for explaining a display method according to an embodiment of the present invention.

  In the single view mode (first mode) shown in FIG. 18, one content view is output, and in the multi view mode (second mode), a plurality of content views are combined and output. First, shooting is performed (S1810).

  Next, the fluctuation state of the user who views the display device is detected using the data captured in step S1810 (S1820).

  Thereafter, the operation is performed in the single view mode (first mode) or the multi view mode (second mode) according to the fluctuation state of the user detected in step S1810 (S1830).

  In this case, the step of operating in the single view mode (first mode) or the multi view mode (second mode) (S1830) is performed when the addition of a user is detected while operating in the single view mode (first mode). When switching to the multi-view mode (second mode) and the user's departure is detected while operating in the multi-view mode (second mode), the mode can be switched to the single-view mode (first mode).

  In addition, when the user's departure is detected in the state of operating in the multi-view mode, the mode is switched to the single view mode (first mode), and among the plurality of content views output in the multi-view mode (second mode). The viewing environment information of the content view corresponding to the user who has left can be stored.

  In addition, when the user who has left is restored, the content view corresponding to the user who has left can be reconstructed using the viewing environment information of the content view, and a plurality of content views including the reconstructed content view can be output.

  On the other hand, when the public mode is set, switching between the multi-view mode (second mode) and the single view mode (first mode) according to the user's change state, and when the private mode is set, Even when a user's fluctuation state is detected, switching between the multi-view mode (second mode) and the single-view mode (first mode) is prohibited, and a fixed operation can be performed in the multi-view mode (second mode).

  Also, the display device can store the viewing environment information of the content view individually for each user.

  In this case, step S1830 operating in the single view mode (first mode) or the multi view mode (second mode) uses the viewing environment information of the content view corresponding to the new user when the addition of the new user is detected. Thus, a new content view can be configured and a plurality of content views including the new content view can be output.

  Further, when an IR signal output from the remote control device is imaged and a user command is received from the remote control device in a state of operating in the multi-view mode (second mode), the remote control is performed via the captured image of the IR signal. Adjacent users can be detected from the device. The user command can then be applied to a content view corresponding to the detected user.

  Since each of those embodiments has been described above, redundant description and illustration are omitted.

  Meanwhile, a program for performing the method according to various embodiments of the present invention described above can be stored and used in various types of recording media.

  Specifically, the code for performing the above-described method includes RAM (Random Access Memory), flash memory, ROM (ReAd Only Memory), EPROM (ErAsAble ProgramAmmABleAROM, EEPROM (ElectronicAllAleABAAROM), EEPROM It can be stored in various types of recording media that can be read by a terminal, such as a removable disk, a memory card, a USB memory, and a CD-ROM.

Embodiment in which an image call is performed via the display device 100 Hereinafter, when the display device 100 according to an embodiment of the present invention outputs a plurality of contents, a video frame of any one of the contents is displayed on the image call screen. An alternative system and method is described.

  FIG. 19 is a conceptual diagram illustrating a system that provides content via the display apparatus 100 according to the present invention and also provides an image call function together.

  FIG. 19 shows a case where an image call is performed by replacing a video frame for one content with an image call screen. Hereinafter, in order to describe the embodiment of FIG. 19, it will be described in detail through additional configurations and operations of the display apparatus 100 and the glasses apparatus 200 of the present invention.

  20 is a block diagram illustrating a configuration of a display apparatus 100 according to various embodiments of the present invention, and FIG. 21 is a flowchart illustrating an image calling method using the display apparatus 100 of FIG.

  20 to 21, the display apparatus 100 according to various embodiments of the present invention includes a receiving unit 110, a signal processing unit 120, an output unit 130, an interface unit 150, a synchronization signal generating unit 140, an image. A call processing unit 190 and a control unit 160 are provided.

  Since the reception unit 110, the signal processing unit 120, the output unit 130, the interface unit 150, and the synchronization signal generation unit 140 have been described above, the image call processing unit 190 and the control unit 160 will be additionally described here.

  FIG. 22 is a block diagram of the display apparatus 100 illustrating specific configurations of the interface unit 150 and the image call processing unit 190 according to various embodiments of the present invention, and FIG. 23 illustrates the display apparatus 100 of FIG. 24 is a flowchart showing a process of making an image call using FIG. 24. FIG. 24 is a conceptual diagram showing that a video frame of content is replaced with a video frame for an image call screen, and FIG. It is a flowchart which shows the process of performing the image call including the step which displays the message to inquire.

  As shown in FIGS. 22 and 23, the image call processing unit 190 is configured to receive an image call request and connect the image call. Image calling refers to a method of making a call while looking at the other party through a display, and is classified into a circuit switching method using an exchange and a packet switching method. In the latter case, voice can be transmitted in the form of packets using VoIP technology via an IP (Internet Protocol) network. In addition, it can be implemented using various protocols.

  The image call processing unit 190 includes an interface unit 150 that receives an image call connection command, an image pickup unit 191 that performs image pickup, an image call reception unit 192 that receives image call data, and an image call using image data and image pickup data. A call screen processing unit 193 constituting the screen can be provided.

  The interface unit 150 receives a video call connection command. When an image call receiving unit 192 (to be described later) first receives an image call request, the interface unit 150 receives an image call connection command from any one of a plurality of glasses devices 200 corresponding to a plurality of contents. At this time, the control unit 160 described above controls the image call processing unit 190 to connect the image call with the correspondent node that has transmitted the image call request. The interface unit 150 may be implemented by any kind of technical means that can input a call connection command to the display apparatus 100 such as a button or a touch screen. Further, the display device 100 can be located on the surface of the display device 100, a glasses device 200 to be described later, or any device related to the display device 100 such as a remote controller (not shown). For example, the eyeglass device 200 may include an image call connection / end button (see 240 ′ in FIG. 26) that can connect or end the image call to the eyeglass frame part. In this case, when the user makes an image call (that is, when an image call request is received by the display device), the user presses the image call connection / end button (see 240 ′ in FIG. 26) located on the glasses device 200. It is possible to input an image call connection command to the display device 100 by pressing the button. Further, in order to end the image call, the image call can be ended by pressing the image call connection / end button (see 240 'in FIG. 26) again.

  In various embodiments of the present invention, the interface unit 150 detects user motion using data captured by the imaging unit 191 (which may be the same configuration as the imaging unit 170 described above according to the embodiment). A motion detector (not shown) can be provided. That is, when an image call receiving unit 192 described later receives an image call request first, the image pickup unit 191 can pick up an image and detect the user's motion using the picked up data.

  The motion detection unit (not shown) is configured to recognize the motion of an object located outside the display device 100. Specifically, the motion detection unit (not shown) senses what kind of motion has been made by sensing the movement of the user who intends to use the display apparatus 100. For this purpose, a motion detection unit (not shown) images an object such as a user existing within the imaging range of the imaging unit 191 and analyzes the captured image data. That is, the change of the pixel value is tracked by comparing the image data captured first and the image data captured for a certain period of time thereafter. For example, when an image call request is received, when the image capturing unit 191 performs image capturing for a predetermined time, a motion detection unit (not shown) starts comparing image data captured every moment. In the unlikely event that there is no change in the pixel value of image data continuously captured for a certain period of time, or only a minute change within the error range is detected, motion detection is considered as a failure. . On the other hand, if there is a change in the pixel value of the image data captured during a certain time and the change exceeds a certain critical value, it is considered that a motion has been detected. At this time, the motion detection unit (not shown) determines the direction in which the pixel value of the image data has changed, the change range, the position, and the like, and identifies what the actual motion is made by the user. When it is determined that the identified motion matches the already set motion, the motion detection unit (not shown) considers that the command corresponding to the motion is input, and the control unit 160 responds to the command. The display device 100 is operated appropriately.

  In one embodiment of the present invention, the command corresponding to the motion may be a video call connection command. In this case, the control unit 160 controls the image call processing unit 190 to connect the image call with the correspondent node that has transmitted the image call request, and shifts the imaging direction to the direction in which the motion is detected. The imaging unit 191 is controlled.

  The image capturing unit 191 is configured to perform image capturing. Specifically, the image capturing unit 191 captures an image of a user who is installed on the display device 100 and wears the glasses device 200 and transmits the image to a motion detection unit (not shown) or a call. It plays a role of transmitting to the screen processing unit 193. The imaging unit 191 includes all types of imaging means that can capture moving images or stop images, and specifically includes digital cameras, infrared cameras, line cameras, and the like. Further, it may be a partial configuration of the imaging unit 170 described above or another configuration.

  According to an embodiment of the present invention, the imaging unit 191 can transmit data captured for motion detection to the motion detection unit (not shown) described above. In this case, the imaging data can be video data composed of continuous frames, and the motion detection unit analyzes the imaging data to track changes, and as a result, recognizes the motion performed by the user. . When the motion is detected, the control unit 160 controls the image call processing unit 190 to connect the image call to the correspondent node that has transmitted the image call request, and controls the imaging unit 191 to detect the motion. The imaging unit 191 is controlled to shift the imaging direction in the direction. The operation of the image call processing unit 190 will be described later, and the principle of the imaging unit 191 shifting the imaging direction will be described below. However, this is merely an embodiment for helping understanding of the present invention, and it is clarified that the present invention does not exclude various technical means for controlling the imaging of the imaging unit 191. As shown in FIG. 19, the imaging unit 191 can be positioned in the upper center of the display device 100. The imaging unit 191 captures all objects that have a certain resolution and imaging angle and fall within the imaging angle range. When the motion detection unit (not shown) recognizes the image call connection motion of the user in the imaging angle range according to the above-described embodiment, the control unit 160 may be based on the position information where the motion is recognized on the captured video. The horizontal and vertical rotation angles of the imaging unit 191 are calculated, and the distance to the object is calculated. The control unit 160 rotates and moves the imaging unit 191 so that the point where the object is located coincides with the center point of the captured image of the imaging unit 191, and the object is sufficiently captured in consideration of the distance to the object. The image condition necessary for the image call is ensured by extending or contracting the zoom of the imaging unit 191 so as to enter the image. For example, when the image call connection motion is performed at 15 degrees on the right side and 17 degrees on the right side from the center point of the imaging screen of the imaging unit 191, the control unit 160 determines that the corresponding point is the center point of the captured image of the imaging unit 191. The imaging unit 191 is moved so as to match, and the zoom of the imaging unit 191 is reduced so that the upper body of the user falls within the imaging screen of the imaging unit 191.

  In addition, the image capturing unit 191 can transmit data captured to configure the call screen to the call screen processing unit 193. A call screen processing unit 193, which will be described later, receives imaging data from the imaging unit 191 and configures a call screen. Detailed operation of the call screen processing unit 193 will be described later. On the other hand, the data imaged by the imaging unit 191 is transmitted to the image communication device (not shown) of the other party of the user who is making the image call via the display device 100 by the transmission unit (not shown) of the display device 100. Can.

  The image call receiving unit 192 is configured to receive image call data from the correspondent node that transmitted the image call request when the image call is connected. The image call data includes all types of transmission / reception data for image calls. That is, audio data and image data can be transmitted in the form of a line signal or a packet signal. The image call data received via the image call receiving unit 192 is transmitted to a call screen processing unit 193, which will be described later, and used to construct a call screen on the output unit 130.

  The call screen processing unit 193 plays a role of configuring an image call screen using image data and imaging data. That is, the image data received via the image call receiving unit 192 and the image data captured by the image capturing unit 191 are received, and the image call screen is configured on the output unit 130. The control unit 160 controls the output unit 130 so that the image call screen is displayed on the output unit 130, which will be described later. As an embodiment, as shown in FIG. 19, the image call screen displays the image call partner in a large size on the output unit 130, and the user who has input the image call connection command is displayed on the output unit 130 as a small screen. It may be a form.

  Hereinafter, the control unit 160 in the present embodiment will be described.

  First, when an image call connection command is input through the interface unit 150, the control unit 160 causes the image call processing unit 190 to connect the image call to the correspondent node that has transmitted the image call request. Control. The image call processing unit 190 receives the image call request from the correspondent node, and starts the image call when the image call connection command is input. That is, the image data transmitted from the other party can be signal-processed and transmitted to the output unit 130, and the audio data can be decoded, modulated, and transmitted to the display apparatus 100. The signal processing for the image data may be output using the signal processing unit 120 of the display apparatus 100 after being processed according to the reception protocol of the signal processing unit 120 of the display apparatus 100 described above, or a separate signal processing unit It may be processed and displayed via (not shown).

  Second, when the image call is connected, the control unit 160 replaces the video frame of the content corresponding to the glasses device 200 that has transmitted the image call connection command among the plurality of glasses devices 200 with the image call screen. The output unit 130 can be controlled. That is, when any one of the users wearing the glasses device 200 and viewing different content starts an image call with the other party, the output unit 130 displays the video frame of the content viewed by the user. Is replaced with a video frame for the image call screen. For example, in FIG. 24, one user views one content including a video frame 1-1, a video frame 1-2, a video frame 1-3, and the like, and the other user views a video frame 2-1, A video data stream in the case of viewing other contents including a video frame 2-2, a video frame 2-3, and the like is shown. At this time, the video frame of the content viewed by the user who started the image call is replaced with image call-1, image call-2, and image call-3 which are frames representing the image call screen. In this way, when two users are watching different contents from the beginning, an image call can be made only by swapping the video frame without changing the frame rate separately. However, there may be a case where a plurality of users wearing the glasses device are viewing the same content. In this case, when an image call is connected, another user must be able to make an image call without any influence on a user who does not make an image call and continues to view the same content. Accordingly, the frame rate conversion unit 122 described above increases the frame rate of the content provided from the video processing unit 121 twice, and the output unit 130 displays the video frame of the content originally displayed and the video for the image call screen. Display with alternating frames. In this case, since the video frame for the image call screen may not reach the screen size and resolution provided by the display apparatus 100, additional correction or upscaling work can be performed.

  Third, when the above-described motion detection unit (not shown) analyzes the imaging data and detects a preset user motion, the control unit 160 makes an image call with the correspondent node that transmitted the image call request. The image call processing unit 190 can be controlled to connect. Next, the imaging unit 191 is controlled to shift the imaging direction to the direction in which the user motion is detected. The operations of the motion detection unit (not shown), the image call processing unit 190, and the imaging unit 191 are as described above.

  Fourth, when an image call request is received, the control unit 160 can control the output unit 130 to display a message for inquiring whether or not the image call has been performed. As described above, a motion detection unit (not shown) can detect a user's motion and connect an image call, but can inquire about the presence / absence of a call via the output unit 130. In this case, the user can connect an image call via the interface unit 150 described above. As described above, the image call connection / end button (see 240 ′ in FIG. 26) provided in the eyeglass frame portion of the eyeglass device may be an embodiment. However, in the present invention, various visual means can be mobilized to inquire whether or not the image call is performed, and not only the visual means but also various cognitive means can be utilized.

  Hereinafter, the image call method according to the present invention will be described with reference to FIGS. Since the operation of the specific configuration has been described above, the overall operation is schematically described here.

  When some users wear glasses apparatus 200 and view different contents (S2110, S2305, S2510) and there is an image call request (S2120-Y, S2310-Y, S2520-Y), this is received. (S2130, S2315, S2530). At this time, the user who wears the glasses device 200 and views the content can respond to the image call request, and the display device 100 can display a message for inquiring whether or not the image call is performed (S2540). The response intention display can be input as an image call connection command via the interface unit 150 (S2310-Y), and the motion detection method using the captured video for the user can be an embodiment ( S2330). When an image call connection command input via the interface unit 150 or a motion corresponding thereto is detected (S2330-Y), an image call is started (S2335). When the image call starts, the video frame of any one of the plurality of contents is replaced with the image call screen (S2150, S2355, S2560). Therefore, other users who have been viewing different contents can continue to view their contents without any interruption. However, when a plurality of users are viewing one content, the frame rate is adjusted and the content and the image call screen are alternately arranged and displayed. On the other hand, when the user's motion is detected and an image call is started, the image capturing unit can shift the image capturing direction to the direction in which the motion is detected, and an appropriate image call screen can be configured (S2340). When an image call is made, an image call screen can be configured using the image call data received from the correspondent node and the image data captured by the image capturing unit (S2345, S2350). In addition, the audio data included in the image call data can be processed and transmitted to the glasses apparatus that has transmitted the image call connection command (S2360). When the image call ends, the original content continues to be displayed (S2160-Y, S2365-Y, S2570-Y).

  Hereinafter, the eyeglass device 200 according to the present embodiment will be described.

  FIG. 26 is a block diagram for explaining the configuration of the eyeglass device 200 according to various embodiments of the present invention. In particular, the glasses apparatus 200 of FIG. 26 is linked to the display apparatus 100 that alternately displays a plurality of contents in units of video frames, and further includes an image call connection / end button 240 ′ in the glasses apparatus 200 described above.

  The image call connection / end button 240 ′ is configured to connect or end the image call. When the user makes an image call (that is, when an image call request is received at the display device), the user presses the image call connect / end button 240 ′ located on the glasses device 200 and displays an image on the display device 100. A call connection command can be input. In addition, in order to end the image call, the image call can be ended by pressing the image call connection / end button 240 ′ again.

  As described above, the control unit 220 controls the shutter glass driving unit 230 so that a driving signal for driving the first shutter glass unit 250 and the second shutter glass unit 260 is generated based on the synchronization signal. Control. When the image call connection is made while a plurality of users are viewing different contents, it is already in a situation where different contents are mixed and displayed on the display device 100, and therefore no separate synchronization process is necessary. However, when it is not a multi-view situation, that is, when an image call connection is made to one user while viewing the same content, the display apparatus 100 is switched to multi-view as described above. Thereby, synchronization with the display device 100 is required. At this time, the control unit drives the first shutter glass unit 250 and the second shutter glass unit 260 in accordance with the synchronization signal transmitted to the display device 100. However, when the image call is finished and the state is changed to a state where the same content is viewed again, the control unit stops the operations of the first shutter glass unit 250 and the second shutter glass unit 260.

  Hereinafter, with reference to FIG. 27, a description will be given of a polarization method applicable when content is alternately displayed or mixedly displayed.

  The display apparatus 100 described above may further include a polarizing member 180. The polarizing member 180 may include a liquid crystal layer (not shown) for polarizing an image. The display apparatus 100 uses different driving voltages to control the liquid crystal layer for each horizontal line or vertical line, and polarizes the content image emitted from the display apparatus 100 in a specific direction. At this time, polarized content images may be alternately displayed. For example, one content can be displayed by being polarized in the horizontal direction, and then the other content can be displayed by being polarized in the vertical direction. This process is repeated. The respective images can be viewed through the glasses apparatus 200-3 having a horizontal polarization lens and the glasses apparatus 200-4 having a vertical polarization lens. As another embodiment, video information of different contents can be included in different areas of one video frame. In this case, each region can be displayed by being polarized in the other direction, and can be viewed through a glasses device having a lens that matches each polarization direction.

  At this time, the eyeglass devices 200-3 and 200-4 used for viewing the display device 100 may include a polarizing lens that matches the polarization direction of the content to be viewed. Through this, each glasses apparatus allows only the polarized image to pass, so that the user can view only the desired content. Since each glasses apparatus 200-3 and 200-4 does not require a separate synchronization operation with the display apparatus 100, it is highly economical and has an effect of reducing the flicker phenomenon that occurs in the synchronization process. FIG. 27 shows a case in which a video is viewed with the glasses apparatus 200-3 and 200-4 with a polarized lens when video frames related to content polarized in the horizontal direction and the vertical direction are alternately displayed. Yes.

  When the present system is used for a video call, any one of a plurality of polarized videos can be replaced with a video call screen as described above. That is, the display device 100 receives the image call data and alternately displays the polarized image in a specific direction while displaying the image call data, or displays the image of the area corresponding to the image call screen on the screen (display unit) while mixing and displaying. Polarize.

  In the present invention, including the above-described configuration, a plurality of people can view different contents via one display device 100 and can make a video call without affecting the viewing of others.

Embodiment for storing a video frame substituted at the time of an image call Hereinafter, a system capable of storing a video frame which was a video frame substituted at the time of an image call) and displaying it after the end of the image call And the method will be described.

  FIG. 28 is a block diagram illustrating a configuration of the display apparatus 100 according to various embodiments of the present invention, and FIG. 29 is a flowchart illustrating an image calling method using the display apparatus 100 of FIG.

  Referring further to FIG. 28, the display apparatus 100 according to various embodiments of the present invention includes a receiving unit 110 that receives content, a signal processing unit 120 that processes the received content, and content that has been signal processed. An output unit 130 for displaying the image, a synchronization signal generation unit 140 for generating a synchronization signal, an image call processing unit 190 for processing an image call request, a storage unit 180 for storing video frames of content, and the display device 100.

  The storage unit 180 is configured to store video frames of content. Specifically, when an image call starts, a video frame of content that is scheduled to be displayed from that point but is not displayed instead of the image call screen is stored. As described above, when an image call is connected while a certain user is viewing the content, the video frame of the content is replaced with the image call screen, so that the user can no longer view the content. If the display device 100 is stored in the display device 100 from the beginning or receives content from various recording medium playback devices connected to the display device 100 and displays the content, the viewing can be performed after the image call is finished. In order to continue viewing the interrupted content, it is only necessary to receive and display the content stored in the display device 100 or the recording medium playback device again. However, there may be a case where restrictions are imposed on receiving and displaying content in terms of time or cost, such as receiving content in real time using a broadcast network or the Internet. Also, even if there is no such time or physical limitation, in the case of content that continues with a movie, it must be possible to continue viewing from the point of time when viewing is stopped while starting an image call. For example, as shown in FIG. 33, the user may make an image call with a cute niece while watching a drama, or an important scene of a drama that was being watched while making an image call with a niece may be missed, or a drama There is a possibility that advertisement will appear after the end. At this time, if the broadcast time of the drama is constrained, the user may be unable to re-view for the time being and can re-view, but may have to pay a separate fee. . Even when the drama can be received and viewed again, there is an inconvenience that the search must be made until the viewing is stopped. In the present invention, when an image call starts via the storage unit 180 as described above, a display is scheduled from that point, but a video frame of content that is not displayed instead of the image call screen is stored. When the image call ends, the control unit 160 controls the output unit 130 to display a combination of the video frame stored in the storage unit 180 and the video frame of content that is not substituted for the image call screen. Therefore, even when the user makes an image call while viewing the content, the user stores the content he / she is viewing in the storage unit 180 and then continues to the time when the image call ends. Can be viewed. Here, the storage unit 180 may be various recording medium playback devices that exist in the display device 100 or are connected to the display device 100.

When an image call connection command input via the interface unit 150 or a motion corresponding thereto is detected (S3130-Y), an image call is started (S3135). When the image call starts, the video frame of any one of the plurality of contents is replaced with the image call screen (S2950, S3155, S3560). Therefore, other users who have been viewing different contents can continue to view their own contents without any interference. However, when a plurality of users are viewing one content, the frame rate is adjusted and the content and the image call screen are alternately arranged and displayed. On the other hand, when the user's motion is detected and the image call is started, the image capturing unit can shift the image capturing direction to the direction in which the motion is detected, and an appropriate image call screen can be configured (S3140). When an image call is made, an image call screen can be configured using the image call data transmitted from the correspondent node and the image data captured by the image capturing unit (S3145, S3150). Further, the video frame of the content substituted for the image call screen is stored in the storage unit (S2960, S3160, S3570). Then, the audio data included in the image call data can be processed and transmitted to the glasses apparatus that has transmitted the image call connection command (S3165). When the image call ends (S2970-Y, S3170-Y, S3580-Y), the stored video frame and the video frame of the content that cannot be substituted for the image call screen are combined and displayed (S2980, S3175, S3590).

  FIG. 36 is a block diagram for explaining the configuration of the eyeglass device 200 according to various embodiments of the present invention. In particular, the glasses apparatus 200 of FIG. 36 works in conjunction with the display apparatus 100 that alternately displays a plurality of contents in units of video frames, and includes an input unit 240, a control unit 220, a shutter glass driving unit 230, a communication interface unit 210, a first interface. A shutter glass portion 250 and a second shutter glass portion 260 are provided.

  Since the shutter glass driving unit 230, the communication interface unit 210, the first shutter glass unit 250, the second shutter glass unit 260, and the control unit 220 have been described above, a detailed description thereof will be omitted in order to avoid duplication.

  The input unit 240 is configured to connect or terminate an image call (see FIG. 2). When a user makes an image call (that is, when an image call request is received by the display device), the user can input an image call connection command to the display device 100 via the input unit 240 located in the glasses device 200. . In addition, when terminating an image call, the image call can be terminated via the input unit 240. The input unit 240 may be the same as or included in the image call connection / end button (240 ′ in FIG. 26) as in the above-described embodiment.

  Since the detailed configuration and functions related to the other eyeglass device 200 are included in the above-described embodiment, a duplicate description is omitted.

  The present invention includes the above-described configuration, and even when the user makes an image call while viewing the content, the user stores the content he / she has viewed in the storage unit 180, The video can be watched again after the video call ends.

Embodiments in which Display Device Restricts Conversion of Content View Hereinafter, a system and method in which display device 100 restricts conversion of content view according to various embodiments of the present invention will be described.

  As shown in FIG. 5, the display device 100 according to the present embodiment includes a plurality of receiving units 110-1, 110-2,. . . 110-n, a plurality of signal processing units 120-1, 120-2,. . . 120-n, an output unit 130, a synchronization signal generation unit 140, an interface unit 150, and a control unit 160.

  Receivers 110-1, 110-2,. . . 110-n, a plurality of signal processing units 120-1, 120-2,. . . , 120-n, the output unit 130, the synchronization signal generation unit 140, and the interface unit 150 have been described above. Therefore, a specific description is omitted to avoid duplication, and the operation of the control unit 160 according to the present embodiment is described. explain.

  The controller 160 can change the operation mode of the display apparatus 100 according to a user selection. The user selects any one of various operation modes such as a single view mode (first mode) for viewing one content and a multi view mode (second mode) for viewing a plurality of content. it can.

  In the single view mode (first mode), one content such as 2D content or 3D content is output, but in the multi view mode (second mode), a plurality of contents are combined as described above. Provided as a content view. Even when the playback of the content assigned to one content view is finished in the multi-view mode (second mode) and the playback of the next content is started, the content view is maintained as it is.

  When two contents are combined and output, the multi-view mode (second mode) can be referred to as a dual view mode. The control unit 160 controls the output unit 130 to output a combination of a plurality of contents when a user inputs a mode change command while operating in accordance with the single view mode (first mode). When the mode is switched to the multi-view mode (second mode), the control unit 160 controls the synchronization signal generation unit 120 and the interface unit 130 to transmit a synchronization signal to each glasses apparatus mapped to each content. .

  On the other hand, a user who views any one of the plurality of content views under the multi-view mode (second mode) can input a content view conversion command for performing a content view conversion operation. . The content view conversion operation means an operation of changing a content view that can be viewed by a plurality of viewers who are viewing each of a plurality of contents.

  For example, when a content view conversion operation is performed while a content view to which a broadcast channel for broadcasting a news program is assigned and a content view to which a sports program is assigned are output, the news program is viewed. The first user who has been watching the sports program now sees the sports program, and the second user who has watched the sports program changes the content view so that the news program is watched.

  Alternatively, the content view conversion operation may be performed so that only a user who inputs a content view conversion command is converted to another content view. That is, in the above-described example, if the first user inputs a content view conversion command, the first user is converted to view the sports program, and the second user performs the sports program in its original state. Come to watch.

  The content view conversion command may be received from a glasses device or a remote controller worn by the user, or may be input via a key button provided on the main body of the display apparatus 100.

  When a content view conversion command is input, the controller 160 restricts the content view conversion operation according to the content type and the user setting state.

  Specifically, the control unit 160 restricts the content view conversion operation for a content view in which a preset type of content is displayed, and for a content view in which the remaining content is displayed. The content view conversion operation can be allowed. For content whose content view conversion operation is restricted, broadcast viewing screens of viewing restriction classes that are prohibited from being viewed by minors, various game program execution screens, messenger program execution screens, e-mail confirmation screens or An SNS screen etc. are mentioned. Since messenger contents, e-mails, SNS message contents, etc. may infringe on personal privacy, even if a content view conversion command is input, the content view conversion is prohibited. In addition, when each game screen is combined and displayed on one display device 100 while executing a game program in which a plurality of users compete with each other, when a content view conversion operation is performed, the strategy of another user is performed. Can be confirmed secretly. Accordingly, even in such a case, the change of the content view can be prohibited. In addition, in the case of a broadcast program screen of a viewing restriction class, conversion of content views can be prohibited for the purpose of preventing minors and the like from secretly viewing. Information on content types for which the content view conversion operation is restricted may be registered in advance in a memory (not shown) in the display apparatus 100 or may be provided from a separate external source.

  On the other hand, according to another embodiment, the control unit 160 can determine whether to perform the content view conversion operation or prohibit the content view according to the setting value of the user. When the dual view mode is started, when the new content is output under the dual view mode, or when a setting command is input under the dual view mode, the control unit 160 outputs to display the setting menu. The unit 130 is controlled. The output unit 130 displays a setting menu for setting whether to prohibit the change of the content view under the control of the control unit 160.

  When the user sets the permission of content view conversion on the setting menu, when a content view conversion command is subsequently input, the control unit 160 performs a content view conversion operation. On the other hand, when the user sets the prohibition of content view conversion via the setting menu, the control unit 160 restricts the content view conversion operation even when a content view conversion command is input.

  FIG. 37 is a diagram for explaining the process of changing the content view. According to FIG. 37, when the multi-view mode (second mode) is started, the display apparatus 100 displays the multi-content frame data 10 in which a plurality of contents are alternately arranged. The eyeglass devices 210 and 220 corresponding to each content are driven in synchronization with the display timing of the corresponding content. Thereby, the user wearing the first glasses device 210 can view the first content C1, and the user wearing the second glasses device 220 can view the second content C2.

  In this state, when a content view conversion command is input through the first glasses device 210, the second glasses device 220, or another input device such as a remote controller, the display device 100 displays the contents C1 and C2. The arrangement order is reversed, and the contents that can be viewed on the first glasses apparatus 210 and the second glasses apparatus 220 are switched to each other.

  Although FIG. 37 shows a method of changing the content arrangement order and changing the content that can be viewed on each of the eyeglass devices 210 and 220, the display device 100 changes the synchronization signal to change the content view. It can also be done. That is, the control unit 160 controls the synchronization signal generation unit 140 to change the synchronization signals corresponding to the first glasses apparatus 210 and the second glasses apparatus 220 while maintaining the content arrangement order as they are, The first glasses apparatus 210 is synchronized with the display timing of C2, and the second glasses apparatus 220 is synchronized with the display timing of C1.

  On the other hand, as described above, the content view switching operation may be limited in some cases. FIG. 38 shows a state where the content view switching operation is restricted.

According to FIG. 38, when the content is restricted according to the type of content or the setting value of the user, the control unit 160 does not perform the content view conversion operation even when the content view conversion command is input. Controls the output unit 130 to display an error message 20 for notifying the change of the content view switching operation.

  FIG. 39 is a block diagram showing a configuration of a display device according to another embodiment of the present invention. 39, the display apparatus 100 includes an output unit 130, a synchronization signal generation unit 140, an interface unit 130, a control unit 160, and an input unit 150.

  The input unit 150 receives a user command such as a content view conversion prohibition command. Such a user command can be input via a button or a remote controller provided on the main body of the display apparatus 100.

  When the multi-view mode (second mode) is started and a content view conversion prohibition command is input in a state where a plurality of contents are displayed on the output unit 130, the control unit 160 changes the currently displayed content. On the other hand, even if a content view conversion command is input, the conversion operation is limited.

  In addition, the input unit 150 can also receive a release command for canceling the content view conversion prohibition command.

  In this case, the control unit 160 restricts the content view conversion operation between the time when the content view conversion prohibition command is input and the time when the release command is input even if the content view conversion command is input. .

  Hereinafter, the glasses apparatus 200 according to various embodiments of the present invention will be described. The eyeglass device 200 according to the present embodiment can take the configuration of FIG. 9 described above.

  That is, the glasses apparatus 200 is linked to the display apparatus 100 that alternately displays a plurality of contents in units of video frames, and includes a communication interface unit 210, a control unit 220, a shutter glass driving unit 230, a first shutter glass unit 250, a second A shutter glass unit 260 and an input unit 240 are provided.

  Since the communication interface unit 210, the shutter glass driving unit 230, the first shutter glass unit 250, and the second shutter glass unit 260 have been described above, only the control unit 220 and the input unit 240 according to the present embodiment will be described here. .

  The input unit 240 receives a content view conversion command. The input unit 240 may include a button for receiving a content view conversion command, and the button may be embodied by a touch sensor or an operation button.

  The control unit 214 controls the interface unit 216 to transmit a content view conversion command input via the input unit 240 to the display apparatus 100. As described above, when the display device 100 is allowed to switch the content view, the content view switching operation is performed. When the display device 100 is restricted, the content view switching operation is not performed.

  Hereinafter, a content view conversion method of the display apparatus according to the embodiment of the present invention will be described.

  FIG. 39 is a flowchart for explaining a content view conversion method of the display apparatus according to the embodiment of the present invention.

  According to FIG. 39, when the multi-view mode (second mode) is started, each of the plurality of contents is processed after being received, and the video frame of each content is displayed as a plurality of content views (S3910).

  Then, a synchronization signal for synchronizing the glasses device corresponding to each content view is generated (S3920) and transmitted to each glasses device (S3930).

  In such a state, when a content view conversion command is received from the glasses apparatus (S3940), it is determined whether or not the content view conversion is permitted (S3950). The display apparatus 100 can determine whether or not to allow the change of the content view in consideration of the content type corresponding to each content view, the user setting state, and the like. For example, a broadcast program screen of a viewing restriction class that is prohibited from being viewed by minors, various game program execution screens, messenger program execution screens, email confirmation screens, or SNS screens may be changed in content view. In addition, even when the user has set a prohibition of conversion, conversion of the content view can be prohibited.

  If it is determined whether to restrict according to the user's setting, the method may further include displaying a setting menu for setting whether to prohibit the conversion of the content view. When a content view conversion command is input in a state where content view conversion permission is set via the setting menu, a step of performing the content view conversion operation and a content view conversion via the setting menu are performed. When the content view conversion command is input in a state where conversion prohibition is set, the method may further include a step of restricting the content view conversion operation.

  If the determination result indicates that it is acceptable, the display apparatus 100 changes the content view (S3960), and if restricted, prohibits the change of the content view (S3970). In this case, no feedback may be provided for the content view conversion instruction, but the fact that the conversion of the content view is limited can be informed via an audio or visual error message.

  FIG. 40 is a flowchart for explaining a content view conversion method of a display apparatus according to another embodiment of the present invention.

  Referring to FIG. 40, when the multi-view mode (second mode) is started, after receiving a plurality of contents, each is processed to display video frames of each content as a plurality of content views (S4010).

  Then, a synchronization signal for synchronizing the glasses device corresponding to each content view is generated (S4020) and transmitted to each glasses device (S4030).

  When a content view conversion prohibition command is received in such a state (S4040), even if a content view conversion command is received thereafter, an error message is displayed (S4060), and the content view conversion operation is not performed. On the other hand, when the content view conversion prohibition command is not received, when the content view conversion command is received (S4070), the content view conversion is performed (S4080). On the other hand, when the release command is input, the content view conversion prohibition command is canceled, and the content view can be converted without restriction. That is, the conversion of the content view can be limited from the time when the content view conversion prohibition command is input to the time when the release command is input.

  As described above, the display apparatus 100 converts the content view according to the convenience of the user, provides the conversion function of the content view to be viewed, and restricts the conversion function of the content view depending on the case or according to the user's request. be able to. As a result, the user can be prevented from misusing the content view conversion function.

  Meanwhile, a program for performing the method according to various embodiments of the present invention described above can be stored and used in various types of recording media.

  Specifically, such a program includes a RAM (Random Access Memory), a flash memory, a ROM (ReAd Only Memory), an EPROM (ErAsAble ProgramAmmAble ROM, an EEPROM (ElectronicAllErABAAROM ROM, a hard disk) The present invention can be provided by being stored in various types of recording media that can be read by a terminal such as a memory card, a USB memory, and a CD-ROM.

Embodiment of Pairing Corresponding Glasses Device According to Directionality of User Signal Hereinafter, a system and method for displaying content by pairing corresponding glasses device according to the directionality of a user signal will be described.

  FIG. 41 is a diagram schematically illustrating a single view mode (first mode) of the display apparatus according to the embodiment of the present invention, and FIG. 42 is a multi-view mode of the display apparatus according to the embodiment of the present invention. (2nd mode) is a figure which shows schematically.

  The display apparatus 100 can operate in a single view mode (first mode) for displaying a single content and a multi-view mode (second mode) for alternately displaying a plurality of contents.

  As shown in FIG. 41, a plurality of users can wear content glasses devices 210 and 220 and view content 1 respectively. Of course, in the single view mode (first mode), it is possible to view without a glasses device.

  As shown in FIG. 42, a plurality of users can view the multi-view mode (second mode) (content 1 and content 2) while wearing the eyeglass devices 210 and 220, respectively.

  The remote control 300 is provided with a touch pad 310 that responds to a user's touch.

  The eyeglass devices 210 and 220 are each provided with a light emitting element 400 so that the display device 100 can detect the positions of the eyeglass devices 210 and 220. In the present embodiment, it is described that the light emitting element 400 is used for position detection. However, this is not limited as long as the display device 100 can detect the positions of the eyeglass devices 210 and 220.

  The light emitting element 400 may be an IR LED.

  The display device 100 according to the present embodiment performs mode switching when a user signal having directionality is received from the remote controller 300. Specifically, when a user signal is received while operating in the single view mode (first mode), the user's glasses device that has input the user signal directly views the content currently displayed, The user's glasses apparatus can switch to a multi-view mode (second mode) in which the current content and other content are combined and displayed so as to view other content.

  For example, when the user on the left side wants to view the content 1 in the multi-view mode (second mode), the user on the left side can touch or drag the touch pad 310 of the remote controller 300 and drag or flip it in the left direction. The remote controller 300 can generate a remote control signal for notifying the direction in which the user has dragged or flipped, and can transmit it to the display apparatus 100.

  When the remote control signal is detected, the display apparatus 100 determines whether the user of any one of the plurality of glasses apparatuses 210 and 220 has operated the remote control based on the directionality included in the remote control signal. Judge whether. The display apparatus 100 can recognize the glasses apparatus of the user who operated the remote controller by comparing the position of each glasses apparatus with the touch direction included in the remote control signal. As an example, as described above, each of the eyeglass devices 210 and 220 is provided with a light emitting element such as an IR LED, and when the corresponding light emitting elements have different colors, the display device 100 captures an image of the front of the display device 100. The position of each eyeglass device can be confirmed using the light emitting element color displayed above.

  When the display apparatus 100 recognizes the user's glasses apparatus 210 located on the left side, the display apparatus 100 controls the recognized glasses apparatus 210 so that the currently displayed content, that is, the content 1 can be viewed as it is, and the remaining users are controlled. In other words, other content, that is, the content 2 is viewed or processed so that the content cannot be viewed. The content 2 can be arbitrarily determined like a broadcast program received on the next channel of the content 1.

  Thus, the display apparatus 100 is switched from the single view mode (first mode) to the multiview mode (second mode) in accordance with a user's remote control operation. Therefore, when only the user wants to view the specific content, the user can switch to the multi-view mode (second mode) with a simple touch operation to prevent the specific content from being exposed to other users. it can.

  FIG. 43 is a block diagram for explaining a configuration of a display device according to an embodiment of the present invention. 43, the display apparatus 100 includes a plurality of receiving units 110-1, 110-2,. . . 110-n, a plurality of signal processing units 120-1, 120-2,. . . 120-n, an output unit 130, an imaging unit 180 ′, a detection unit 170 ′, a control unit 160, an interface unit 150, and a synchronization signal generation unit 140.

  In addition to the following description, the receiving unit 110, the signal processing unit 120, the output unit 130, the control unit 160, the interface unit 150, the synchronization signal generation unit 140, and the imaging unit 180 ′ have functions similar to those described above. Therefore, redundant description is omitted.

  The interface unit 150 receives a directional user signal from the remote controller 300.

  The imaging unit 180 ′ performs an imaging operation for a user including the eyeglass devices 210 and 220. The imaging unit 180 ′ is attached to one side of the display device 100 and can image the front of the display device 100. As a result, glasses images of all users who are viewing the display device 100 can be displayed in the image captured by the imaging unit 180 ′. The imaging unit 180 ′ may be included in the imaging unit of the above-described embodiment or may perform such a function together.

  The detection unit 170 ′ detects the eyeglass devices 210 and 220 corresponding to the directionality using the captured image captured by the imaging unit 180 ′.

  As an example, the detection unit 170 ′ recognizes the color of the light emitting element 400 attached to the plurality of glasses devices 210 and 220 included in the image captured by the imaging unit 180 ′ and is positioned in the touch operation direction. It can detect what kind of glasses device the device is.

  As another example, when the light emitting element is not attached to the eyeglass devices 210 and 220, the detection unit 170 ′ may include the shape and color of each eyeglass device 210 and 220, or a specific mark attached to the eyeglass devices 210 and 220. Can be recognized to identify the eyeglass device.

  The detection unit 170 ′ provides the detection result to the control unit 160.

  When a user signal is input, the control unit 160 controls the detection unit 170 ′ so as to detect the glasses apparatus that has input the user signal. Accordingly, when one eyeglass device is detected as described above, the control unit 160 switches to the multi-view mode (second mode) so that the specific content can be viewed on the detected eyeglass devices 210 and 220.

  Specifically, the control unit 160 controls the other receiving unit that has been inactivated to activate and receive other content. And each receiving part 110-1,110-2 ,. . . , 110-n signal-process each content and display it as a plurality of content views. . . 120-n and the output unit 130 are controlled. The control unit 160 generates a synchronization signal that synchronizes the content view corresponding to the content displayed so far among the plurality of content views and the user's glasses device that has been recognized as having received the user signal. The interface unit 150 is controlled so as to transmit to the corresponding glasses apparatus. Then, for the remaining content views, the synchronization signal generation unit 140 and the interface unit 150 are controlled so as to generate a synchronization signal for synchronizing the remaining glasses apparatus and transmit the synchronization signal to each glasses apparatus. . The content displayed in the remaining content views can be arbitrarily selected.

  When switching to the multi-view mode (second mode), the synchronization signal generation unit 140 synchronizes the glasses devices 210 and 220 detected at the content output timing among the plurality of contents, Among them, a synchronization signal for synchronizing the other eyeglass devices 210 and 220 with the output timing of other contents is output.

  On the other hand, in the above-described embodiment, it has been described that the display apparatus 100 generates the synchronization signals corresponding to the display timing of the contents and transmits the synchronization signals to the glasses apparatuses 210 and 220, but this is merely an example.

  FIG. 44 is a flowchart for explaining a multi-view conversion method according to an embodiment of the present invention.

  First, content is displayed (S4410). In the present embodiment, a single view mode (first mode) for displaying a single content (content 1) is exemplarily displayed.

  Thereafter, a user signal having directionality is received from the remote controller 300 (S4420). The remote control 300 is a remote control 300 including a touch pad 310, and the user signal may be a user touch operation signal that moves in one direction on the touch pad 310. In the present embodiment, an example will be described in which it moves to the left.

  When a user signal is input, an imaging operation is performed (S4430). The imaging operation can be performed on the front side of the display apparatus 100 by a camera attached to the display apparatus 100.

  After the imaging operation, the glasses apparatus 210 corresponding to the directionality is detected among the plurality of glasses apparatuses 210 and 220 included in the captured image (S4440). 41 and 42, the left eyeglass device 210 is exemplified as the eyeglass device 210 corresponding to the directionality. The step of detecting the glasses device 210 recognizes the positions of the light emitting elements 400 attached to the plurality of glasses devices 210 and 220 included in the captured image, and the direction of the plurality of glasses devices 210 and 220 is determined. The eyeglass device 210 corresponding to is detected.

  Thereafter, the multi-view mode (second mode) is switched so that the content (content 1) can be viewed on the eyeglass device 210 in which the content is detected (S4450). The conversion to the multi-view mode (second mode) is performed by receiving new content (content 2) using at least one other receiving unit in addition to the receiving unit that receives content (content 1). ) And new content (content 2) are combined and displayed. The change of the multi-view mode (second mode) synchronizes the glasses device 210 detected at the output timing of the content (content 1) among the plurality of contents, and other content (content 2) among the plurality of contents. ) Output the synchronization signal for synchronizing the other eyeglass device 220 to the output timing.

  On the other hand, when the user inputs a preset touch pattern via the touch pad 310 of the remote controller 300 during viewing in the multi-view mode (second mode), the remote controller 300 enters the multi-view mode (second mode). A remote control signal for ending and switching to the single view mode (first mode) may be transmitted to the display apparatus 100. Here, the preset touch pattern may be the same pattern as the touched pattern for operating in the multi-view mode (second mode), may be a pattern indicating the opposite direction, It may be a pattern of a specific form.

  Thus, the user can easily switch between the single view mode (first mode) and the multi view mode (second mode) using the touch pad attached to the remote control.

  Meanwhile, a program for performing the method according to various embodiments of the present invention described above can be stored and used in various types of recording media.

  Specifically, the code for performing the above-described method is a RAM, a flash memory, a ROM, an EPROM, an EEPROM, a register, a hard disk, a removable disk, a memory card, a USB memory, a CD-ROM, etc. It can be stored in various types of readable recording media.

Embodiment for recording and transmitting multi-view mode (second mode) information in a synchronization signal Hereinafter, recording multi-view mode (second mode) information in the synchronization signal according to various embodiments of the present invention. A transmission system and method will be described.

  The display apparatus 100 according to various embodiments of the present invention includes a plurality of receiving units 110-1, 110-2,. . . 110-n, a plurality of signal processing units 120-1, 120-2,. . . 120-n, an output unit 130, a synchronization signal generation unit 140, an interface unit 150, a control unit 160, and an input unit 170 ''.

  The plurality of receiving units 110-1, 110-2,. . . 110-n, a plurality of signal processing units 120-1, 120-2,. . . 120-n, the output unit 130, the synchronization signal generation unit 140, the interface unit 150, and the control unit 160, in addition to the contents described below, can perform the functions of the above-described configuration corresponding to each. .

  The input unit 170 ″ receives a multi-view viewing command. The multi-view viewing command means a user command for alternately displaying a plurality of contents in units of video frames so that the display apparatus provides different contents to a plurality of users.

  For this, the input unit 170 ″ may be embodied by a touch pad, a key button, a key pad, or the like, or may receive a user command input from a remote control device (not shown) such as a remote controller. Can be In addition to the multi-view viewing command, the input unit 170 ″ can receive various user commands for controlling the display apparatus 100 such as a channel selection command and a volume adjustment command.

  When a multi-view viewing command is input, the control unit 160 can control the interface unit 150 to record and transmit multi-view mode (second mode) information in the synchronization signal. Here, the multi-view mode (second mode) information includes information for notifying the start fact of the multi-view mode (second mode). Whether the display apparatus 100 is operating according to the multi-view mode (second mode) according to whether the received synchronization signal includes multi-view mode (second mode) information. Is determined, and the opening / closing operation of the shutter glass portion is controlled.

  The control unit 160 generates a synchronization signal according to a communication protocol defined with at least one glasses apparatus, and records multi-view mode (second mode) information in a reserved area in the synchronization signal. That is, the control unit 160 generates a synchronization signal in which multi-view mode (second mode) information is recorded in accordance with a wireless communication method performed by the interface unit 150, and transmits the synchronization signal to the glasses apparatus, which will be described later. The interface unit 150 can be controlled.

  The interface unit 150 transmits a synchronization signal to at least one glasses apparatus that is linked to the display apparatus 100. In this case, the interface unit 150 can process the synchronization signal and transmit it to the glasses apparatus according to various wireless communication methods.

  For example, when the interface unit 150 includes a Bluetooth communication module and communicates with the glasses apparatus, the control unit 160 generates an synchronization signal as a transmission packet according to the Bluetooth communication method and transmits the synchronization signal to the glasses apparatus. The unit 150 can be controlled. Hereinafter, the transmission packet generated according to the Bluetooth communication method will be described in more detail with reference to FIG. 46 attached.

  FIG. 46 is a diagram showing a structure of a transmission packet generated according to the Bluetooth communication method according to an embodiment of the present invention.

  As shown in FIG. 46, the transmission packet is synchronized with the display timing of the content and includes time information for opening / closing the shutter glass of the glasses apparatus. Specifically, the time information includes an offset time for opening the left eye shutter glass of the eyeglass device (left shutter open offset), an offset time for turning off the left eye shutter glass (left shutter close offset), and opening the right eye shutter glass. It includes information on an offset time (right shutter open offset) and an offset time (right shutter shutter offset) for turning off the right-eye shutter glass, and these consist of 2-byte packets.

  Here, the time information means time information for opening / closing the shutter glass of the glasses device according to the display timing of any one of the plurality of contents in the multi-view mode (second mode). . The time information in the general mode means time information for opening / closing the shutter glass of the glasses apparatus according to the display timing of the left eye video frame and the right eye video frame of the 3D content.

  On the other hand, the offset time is delay information from the reference time set for each content to the shutter glass open or off time. That is, the eyeglass device opens / offs the left eye shutter glass and the right eye shutter glass when the offset time has elapsed from the reference time point. For example, the reference time is a time when a vertical synchronization signal (ie, frame sync) is generated in the video frame, and information on the reference time can be included in the transmission packet. In addition, information regarding a clock signal used in the display apparatus 100 may be included in the transmission packet.

  That is, as shown in FIG. 46, the information about the reference time and the information about the clock signal are included in a 4-byte BT (Bluetooth (registered trademark)) clock packet and a 2-byte BT clock phase packet in the transmission packet. Accordingly, when the glasses apparatus receives the transmission packet, it synchronizes its own clock signal with the clock signal of the display apparatus 100 using the BT clock packet and the BT clock phase packet, and uses the clock signal to synchronize the vertical synchronization signal. It is possible to open / off the shutter glass by determining whether or not the offset time has been reached from the point in time when the shutter is generated.

  On the other hand, the BT clock including the reference time point information and the clock signal information in the 4-byte BT clock packet has 28 bits, and the remaining 4 bits can be a reserved area. The controller 160 records the multi-view mode (second mode) information in the reserved area in the BT clock packet. For example, when one 3D content is provided in the display apparatus 100, the control unit 160 records “0” in the reserved area (general mode), and when a plurality of contents are alternately displayed, the control unit 160 displays the multi-view mode (second mode). ) “1” can be recorded in the reserved area as information (multi-view mode (second mode)). The glasses apparatus confirms the information recorded in the reserved area, determines the operation mode of the display apparatus 100, and performs an operation corresponding to each mode. Specifically, when “1” is recorded in the reserved area, the eyeglass device opens / offs the left eye shutter glass and the right eye shutter glass at the same time based on the time information, and “0” in the reserved area. Is recorded, the left eye shutter glass and the right eye shutter glass are alternately opened / off based on the time information.

  In addition, the transmission packet is a 2-byte packet including information on the frame sync cycle, a 1-byte packet (frAme sync frAction) for indicating the decimal point information when the frame sync cycle has a decimal point, A 1-byte packet Trem including information regarding the remaining playback time of the currently viewed 3D content, a 1-byte packet Tdis including information regarding the open degree of the glasses device, and the like may be included.

  On the other hand, the interface unit 150 transmits and receives a Bluetooth address (Bluetooth device Address), a PIN code, and the like with the glasses device, and performs pairing (pAiring) according to the Bluetooth communication method. When the pairing is completed, the interface unit 150 can transmit a synchronization signal corresponding to any one of the plurality of contents to the glasses apparatus based on the information acquired through the payment.

  In addition, when pairing with a plurality of eyeglass devices is completed, the interface unit 150 can transmit the same or different synchronization signals to different eyeglass devices based on information acquired through the payment. The interface unit 150 can also transmit the same synchronization signal to some of the eyeglass devices. For example, the interface unit 150 includes a synchronization signal corresponding to the content 1 for the first glasses device, a synchronization signal corresponding to the content 2 for the second glasses device, and a synchronization signal corresponding to the content 1 for the third glasses device. Can be sent.

  For example, in the above-described embodiment, it has been described that the interface unit 150 and the glasses apparatus perform communication according to the Bluetooth communication method, but this is only an example. In other words, communication methods such as infrared communication and ZigBee can be used in addition to the Bluetooth method, and communication can be performed according to various wireless communication methods that can form a communication channel and transmit / receive signals at other short distances.

  In the embodiment described above, the display apparatus and the glasses apparatus communicate with each other according to various wireless communication schemes that can transmit and receive signals by forming a communication channel at a short distance, but this is only an example. That is, the display apparatus provides the glasses apparatus with IR synchronization signals having different frequencies, and the glasses apparatus receives the synchronization signal having a specific frequency and applies the shutter glass according to the display timing of the corresponding content. Of course, it can be opened or turned off.

  On the other hand, in the above-described embodiment, it has been described that the display device 100 generates each synchronization signal corresponding to the display timing of the content and transmits it to the glasses device 200, but this is only an example.

  That is, the control unit 160 can control the interface unit 150 to generate a synchronization signal corresponding to the display timing of each content as one transmission packet according to the Bluetooth communication standard. That is, the interface unit 150 is synchronized with the display timing of the first content to open / off the shutter glass of the glasses device, and synchronized with the display timing of the second content to the shutter glass of the glasses device. Time information for opening / closing. . . , One transmission packet including all the time information for opening / closing the shutter glass of the glasses apparatus in synchronization with the display timing of the nth content can be generated.

  In this case, the interface unit 150 can generate a transmission packet by matching information for the glasses apparatus with the display timing of each content. For example, the interface unit 150 can match information for different glasses devices for each content according to the order in which the video frames of the content are arranged. That is, when two contents are provided in the multi-view mode (second mode), the first, third,. . . , The nth video frame of the content matches the information for the first glasses device, and the second, fourth,. . . , The video frame of the content arranged at the (n + 1) th time can match information for the second glasses apparatus (where n is an odd number). The interface unit 150 can transmit the generated transmission packet to the glasses apparatus so as to include a synchronization signal for each of the plurality of contents. The eyeglass device can open / off the shutter glass using a synchronization signal including its own eyeglass device information among the synchronization signals for each of the plurality of contents.

  FIG. 47 is a block diagram for explaining the configuration of the eyeglass device according to the embodiment of the present invention. As shown in FIG. 47, the eyeglass device 200 includes a communication interface unit 210, a control unit 220, a shutter glass driving unit 230, a first shutter glass unit 250, and a second shutter glass unit 260.

  In addition to the contents described below with respect to the components, the functions of the components described above corresponding to the components can be performed.

  The communication interface unit 210 receives a synchronization signal from the display device. Specifically, the communication interface unit 210 can communicate with the display apparatus according to various wireless communication methods and receive a synchronization signal. For example, the communication interface unit 210 includes a Bluetooth communication module, and can perform communication according to the Bluetooth communication method with the display device.

  As described above, the synchronization signal can be received in the form of a transmission packet in accordance with the Bluetooth communication method, and is synchronized with the display timing of the content, and the first shutter glass unit 250 and the second shutter of the glasses apparatus 200. Time information for opening / closing the glass part 260 may be included. Since the information included in the transmission packet has been described above with reference to FIG. 46, a duplicate description is omitted.

  The controller 220 controls the overall operation of the glasses apparatus 200. In particular, the control unit 220 transmits the synchronization signal received by the communication interface unit 210 to the shutter glass driving unit 230 and controls the operation of the shutter glass driving unit 230.

  Specifically, when the synchronization signal includes the multi-view mode (second mode) information, the control unit 220 determines whether the first shutter glass unit 250 and the second shutter glass unit 250 and the second shutter are in accordance with the multi-view mode (second mode) information. The shutter glass drive unit 230 is controlled so as to adjust the open timing of the shutter glass unit 260.

  For example, when the synchronization signal is received in the form of a transmission packet according to the Bluetooth communication method, the control unit 220 checks whether multi-view mode (second mode) information is included in the reserved area in the transmission packet. The shutter glass driving unit 230 generates a driving signal for driving the first shutter glass unit 250 and the second shutter glass unit 260 depending on whether or not information on the multi-view mode (second mode) is included. To control.

  Specifically, when 3D content is displayed on the display device, the control unit 220 alternately opens the first shutter glass unit 250 and the second shutter glass unit 260 and includes multi-view mode (second mode) information. When the synchronized signal is received, the first shutter glass unit 250 and the second shutter glass unit 260 are displayed according to the display timing of the content corresponding to the glasses device 200 among the plurality of contents displayed on the display device. Open.

  That is, if it is determined that the multi-view mode (second mode) information is not included in the synchronization signal, the control unit 220 determines whether the first shutter glass unit 250 and the first shutter glass unit 250 and the second one are based on the time information included in the synchronization signal. The shutter glass driving unit 230 is controlled so that a driving signal for alternately opening / closing the two shutter glass units 260 is generated. Accordingly, the first shutter glass unit 250 and the second shutter glass unit 260 can be opened / off in synchronization with the display timing of the left eye video frame and the right eye video frame of the 3D content.

  Then, when it is determined that the multi-view mode (second mode) information is included in the synchronization signal, the control unit 220 determines that the first shutter glass unit 250 and the second shutter glass unit 250 and the second shutter are based on the time information included in the synchronization signal. The shutter glass drive unit 230 is controlled so that a drive signal for opening / closing both the shutter glass unit 260 and the shutter glass unit 260 is generated. Accordingly, the first shutter glass unit 250 and the second shutter glass unit 260 may be opened when a video frame for any one of a plurality of contents is displayed.

  On the other hand, in the above-described embodiment, it has been described that the display device 100 generates each synchronization signal corresponding to the display timing of the content and transmits it to the glasses device 200, but this is only an example. That is, the display apparatus 100 can generate a synchronization signal corresponding to the display timing of each content as a single transmission packet according to the Bluetooth communication standard and transmit it to the glasses apparatus.

  FIG. 48 is a flowchart for explaining a multi-view display method of the display apparatus according to the embodiment of the present invention.

  First, a multi-view viewing command is received (S4810). The multi-view viewing command means a user command for alternately displaying a plurality of contents in units of video frames so that the display apparatus provides different contents to a plurality of users.

  Thereafter, when a multi-view viewing command is input (S4810-Y), a plurality of contents are displayed (S4820). Specifically, when a multi-view viewing command is input, a plurality of different contents are received to form each video frame of the plurality of contents, and the video frames of the plurality of contents are alternately arranged and displayed. To do.

  Then, a synchronization signal including multi-view mode (second mode) information is generated (S4830). The multi-view mode (second mode) information includes information for notifying the start fact of the multi-view mode (second mode) as information for notifying the fact when multi-command viewing is input. .

  The multi-view mode (second mode) information can be recorded in a reserved area of a synchronization signal generated according to a communication protocol defined with at least one glasses apparatus. For example, when the synchronization signal is generated in the form of a transmission packet according to the Bluetooth communication method, the multi-view mode (second mode) information can be recorded in the reserved area in the BT packet. This has been described above with reference to FIG.

  Thereafter, a synchronization signal is transmitted (S4840). Specifically, the synchronization signal is transmitted to at least one glasses device that is linked to the display device. For example, in the case of the Bluetooth communication system, the device ID acquired in the pairing process is matched with a transmission packet including time information corresponding to the display timing of each content. And based on the information acquired through pairing, a transmission packet is transmitted to corresponding glasses apparatus.

  FIG. 49 is a flowchart for explaining a control method of the eyeglass device according to the embodiment of the present invention. In particular, FIG. 49 illustrates a method of controlling the eyeglass device that opens the first and second shutter glass portions in accordance with the display timing of content displayed on the display device in conjunction with the display device.

  First, a synchronization signal is received from the display device (S4910). For this reason, it is possible to communicate with the display device according to various communication methods.

  Thereafter, it is determined whether multi-view mode (second mode) information is included (S4920). For example, when a transmission packet generated according to a Bluetooth communication method is received, it is determined whether multi-view mode (second mode) information is included in the reserved area in the transmission packet.

  If multi-view mode (second mode) information is included in the synchronization signal (S4920-Y), the open timings of the first and second shutter glass portions are adjusted according to the multi-view mode (second mode) information. (S4930).

  Specifically, when 3D content is displayed on the display device, the first and second shutter glass portions are alternately opened, and a synchronization signal including multi-view mode (second mode) information is received. The first and second shutter glass portions can be opened at the display timing of the content corresponding to the glasses device among the plurality of contents displayed on the display device. Thereby, the user can view 3D content in the general mode, and can view any one of the plurality of content in the multi-view mode (second mode).

Embodiments of Glasses Device for Providing Information on Whether Glasses Device Operates Normally In the following, when providing contents according to various embodiments of the present invention, information on whether the glasses device is operating normally is provided. The glasses apparatus will be described.

  FIG. 50 is a block diagram illustrating a configuration of a display apparatus according to various embodiments of the present invention.

  As shown in FIG. 50, the display apparatus according to various embodiments of the present invention includes a plurality of receiving units 110-1, 110-2,. . . 110-n, a plurality of signal processing units 120-1, 120-2,. . . 120-n, an output unit 130, a synchronization signal generation unit 140, an interface unit 150, a control unit 160, and an audio data transmission unit 170. In addition to the contents described below, the constituent elements perform the functions of the corresponding constituent elements described above, and redundant descriptions are omitted as much as possible.

  When the connection request message for transmitting the synchronization signal is received from the glasses device, the control unit 160 controls the audio data transmission unit 170 to transmit the audio data corresponding to one content to the glasses device.

  Then, when the connection request message is received, the control unit 160 transmits a response message to the glasses device, and the interface unit 150 and the glasses device according to the communication protocol defined between the glasses device. The connection operation between them is performed.

  For convenience of explanation, it is assumed that the interface unit 150 includes a Bluetooth communication module and performs a connection operation according to the Bluetooth communication module and the Bluetooth communication module provided in the glasses apparatus.

  Specifically, the glasses apparatus broadcasts an inquiry message (Inquiry Message Age) to perform a pairing operation, and searches for a display apparatus within a range where Bluetooth communication is possible. When the inquiry message is received, the control unit 160 controls the interface unit 150 to transmit a response message (Extended Inquiry Response, EIR) to the glasses apparatus. Here, the response message may include a Bluetooth address (Bluetooth device Address), a device name (NAme), a COD (ClAs of Device), clock information, and the like.

  On the other hand, the glasses apparatus that has received the response message transmits a transmission packet including a Bluetooth address, a device type (Type), and the like to the display apparatus 100. When the corresponding transmission packet is received via the interface unit 150, the control unit 160 can control the interface unit 150 to transmit / receive a PIN code (PINCode) to / from the glasses apparatus, and can perform a pairing operation with the glasses apparatus. . Here, the control unit 160 performs the pairing operation by registering the display device by automatically inputting the PIN code even if the user does not directly input the PIN code. However, the present invention is not limited to this, and the pairing process may be performed through a method in which the user directly inputs the PIN code of the display apparatus.

  As described above, when the inquiry message is received from the glasses device, the control unit 160 transmits a response message in response to the inquiry message so that the interface unit 150 and the glasses device can communicate with each other. At this time, when an inquiry message is received from the glasses apparatus, the control section 160 can control the audio data transmission section 170 so that audio data modulated by the RF method is transmitted to the glasses apparatus.

  On the other hand, when information indicating whether or not audio data is received is received from the glasses apparatus, the control unit 160 controls the received information to be displayed on the screen (display unit) of the output unit 130 in a UI form. Here, information indicating whether or not audio data is received is recorded in a reserved area in a transmission packet transmitted during the connection operation between the interface unit 150 and the eyeglass device. As described above, the glasses apparatus that has received the response message transmits a transmission packet including a Bluetooth address, a device type (type), and the like to the display apparatus 100. That is, the glasses apparatus can record information indicating whether or not audio data is received in the reserved area in the transmission packet and transmit the information to the display apparatus 100.

  Accordingly, the control unit 160 can determine whether or not audio data is received by the glasses apparatus with reference to the information recorded in the reserved area in the transmission packet. For example, when the control unit 160 reads the bit value “1” from the reserve area, the control unit 160 determines that the audio data is received by the glasses apparatus, and when the bit value “0” is read from the reserve area, It can be determined that no audio data is received by the device.

  However, this is only an example, and information indicating whether or not audio data is received can be recorded in various forms according to a method set in advance with the glasses apparatus. That is, when no bit value is recorded in the reserved area in the transmission packet, the control unit 160 can determine that the audio data is not received by the glasses apparatus.

  On the other hand, the control unit 160 can control the output unit 130 so that information indicating whether or not audio data is received is displayed on the screen (display unit) in UI form. In this case, the control unit 160 can display information on the connection state of the interface unit 150 together on the UI. Specifically, the control unit 160 outputs at least one of the message that the audio data is normally received by the glasses device and the message that the interface unit 150 is normally connected to the glasses device in the OSD form. Can be displayed on the screen (display section). Thereby, the information regarding the operation state of the glasses device can be provided to the user.

  On the other hand, the control unit 160 can control the interface unit 150 to transmit any one of the synchronization signals corresponding to each of the plurality of contents to the glasses apparatus that has completed the connection operation.

  Here, the synchronization signal transmitted to the eyeglass device can be set as a default. For example, it is assumed that the video frame of the first content and the video frame of the second content are displayed alternately. In this case, the synchronization signal corresponding to the first content among the synchronization signal corresponding to the first content and the synchronization signal corresponding to the second content may be set to be transmitted to the glasses apparatus.

  Meanwhile, when a request message for requesting transmission of another synchronization signal is received from the glasses apparatus, the control unit 160 may control the interface unit 150 to transmit another synchronization signal. In this case, the control unit 160 modulates audio data associated with each content into different frequency signals, and transmits audio data associated with content corresponding to other synchronization signals using a new frequency band. can do.

  On the other hand, although it has been described that the synchronization signal set as a default is transmitted to the eyeglass device in which the connection operation has been completed in the above-described embodiment, this is merely an example.

  That is, the control unit 160 can control the interface unit 150 to transmit synchronization signals that are the same or different from each other based on information acquired through the pairing operation to different glasses devices. The interface unit 150 can also transmit the same synchronization signal to some of the eyeglass devices. For example, the interface unit 150 includes a synchronization signal corresponding to the content 1 for the first glasses device, a synchronization signal corresponding to the content 2 for the second glasses device, and a synchronization signal corresponding to the content 1 for the third glasses device. Can be sent.

  In addition, the control unit 160 can also control the interface unit 150 so as to generate a synchronization signal corresponding to the display timing of each content as one transmission packet according to the Bluetooth communication standard. That is, the interface unit 150 is synchronized with the display timing of the first content and is synchronized with the time information for opening / closing the shutter glass of the glasses device and the display timing of the second content, and the shutter of the glasses device. Time information for opening / closing the glass. . . , One transmission packet including all the time information for opening / closing the shutter glass of the glasses apparatus can be generated in synchronization with the display timing of the nth content.

  In this case, the interface unit 150 can generate a transmission packet by matching information for the glasses apparatus with the display timing of each content. For example, the interface unit 150 can match information for different glasses devices for each content according to the order in which the video frames of the content are arranged. That is, when two contents are provided in the multi-view mode (second mode), the first, third,. . . , The nth video frame of the content matches the information for the first glasses device, and the second, fourth,. . . , The video frame of the content arranged at the (n + 1) th time can match information for the second glasses apparatus (where n is an odd number). And the interface part 150 can transmit the transmission packet produced | generated so that the synchronization signal with respect to each of several content may be included to a spectacles apparatus. The eyeglass device can open / off the shutter glass using a synchronization signal including its own eyeglass device information among the synchronization signals for each of the plurality of contents.

  Meanwhile, the control unit 160 may modulate audio data associated with each content into different frequency signals and transmit audio data associated with each content using different frequency bands. At this time, the control unit 160 can write information about the glasses apparatus in each audio data, and the glasses apparatus can selectively receive and output audio data corresponding to its own glasses apparatus information.

According to FIG. 51, the glasses apparatus 200 includes a communication interface unit 210, an audio data receiving unit 241, and a control unit 220. In particular, the eyeglass device 200 can be linked to a display device that alternately displays each of a plurality of contents. Hereinafter, it will be clarified that the configuration of the eyeglass device 200 described above can be included except for the configuration of the eyeglass device 200.

  The communication interface unit 210 may transmit a connection request message to the display apparatus in order to receive a synchronization signal corresponding to any one of a plurality of contents. That is, when the Bluetooth communication module is provided, the communication interface unit 210 transmits an inquiry message to the display device. Then, the response message transmitted from the display device can be received to perform the pairing operation. This has been described above with reference to FIG.

  On the other hand, when the display device and the communication interface unit 210 are connected according to a communication protocol defined with the display device, the communication interface unit 210 can receive a synchronization signal from the display device.

  Specifically, when the display device is in the multi-view mode (second mode), the communication interface unit 210 synchronizes the glasses device with the display timing of the video frame for any one of the plurality of contents. The synchronization signal is received. When the display device is in the general mode, the communication interface unit 210 may receive a synchronization signal for synchronizing the glasses device with the display timing of the left eye video frame and the right eye video frame of the 3D content. it can.

  The audio data receiving unit 241 receives audio data from the display device. Specifically, the audio data receiving unit 241 can receive audio data that is modulated according to the RF communication method and transmitted in a preset frequency band. Here, the audio data receiving unit 241 can receive audio data corresponding to the synchronization signal received from the communication interface unit 210. That is, it may be audio data associated with content corresponding to the synchronization signal.

  The controller 220 controls the overall operation of the glasses apparatus 200.

  In particular, when a response message to the connection request message is received, the controller 220 selects an audio data receiver 241 so as to select a preset frequency band and receive audio data corresponding to one content. Control.

  For this reason, the control unit 220 can control the audio data receiving unit 241 to select a frequency band defined in advance between the display device and the glasses device 200 in order to receive audio data. Alternatively, the control unit 220 scans a specific frequency band, detects a frequency band in which audio data exists, controls the audio data reception unit 241 to select the detected frequency band, and receives the audio data. can do.

  And the control part 220 can be controlled to transmit to the display apparatus via the communication interface part 210 so that the information showing the reception presence or absence of audio data may be transmitted. Specifically, the control unit 220 determines whether audio data is stored in a reserved area in a transmission packet transmitted to connect the display device and the communication interface unit 210 according to a communication protocol defined between the display device and the display device. Information indicating the presence or absence of reception can be recorded.

  That is, when a response message is received from the display device in a process in which the communication interface unit 210 performs a connection operation with the display device according to the Bluetooth communication protocol, the control unit 220 includes a Bluetooth address, a device type (type), and the like. The communication interface unit 210 can be controlled to transmit the transmission packet to the display apparatus 100. In this case, the control unit 220 can record a specific bit value indicating whether or not audio data is received in the reserved area of the transmission packet. For a more specific description, reference is made to FIG.

  FIG. 52 is a view for explaining the structure of a transmission packet transmitted from the glasses apparatus to the display apparatus according to an embodiment of the present invention.

  When the response message is received from the display device, the glasses device may transmit a transmission packet to the display device by configuring a transmission packet to include various information for pairing with the display device.

  As a result, when a transmission packet is composed of 17 bytes, a 1-byte and 4-byte reserved area (Reserved) exists. The control unit 220 can record information indicating whether or not audio data is received in a 1-byte reserved area or a 4-byte reserved area. For example, the control unit 220 records a bit value “1” in the reserved area to indicate that audio data is received, and stores a bit value “1” in the reserved area to indicate that audio data is not received. 0 "can be recorded. Accordingly, the display device that has received the transmission packet can determine whether the audio signal is normally transmitted to the glasses device and provide it to the user.

  FIG. 53 is a block diagram showing a detailed configuration of the eyeglass device according to the embodiment of the present invention. 53, the glasses apparatus 200 includes a communication interface unit 210, an audio data receiving unit 241, a control unit 220, a shutter glass driving unit 230, a first shutter glass unit 250, a second shutter glass unit 260, and an input unit 240.

  Meanwhile, the input unit 240 may receive a user command for requesting transmission of a synchronization signal. Specifically, when the user touches a touch sensor or an operation button provided in the input unit 240 in a state where the connection operation with the display apparatus is completed, the control unit 220 sends a request message requesting transmission of another synchronization signal. The communication interface unit 210 can be controlled to transmit to the display device. Thereby, the communication interface unit 210 can receive a synchronization signal different from the synchronization signal received from the display device.

  Hereinafter, the display apparatus 100 and the glasses apparatus 200 according to various embodiments of the present invention that perform the above-described functions will be described in detail.

  FIG. 58 is a block diagram for explaining a configuration of a display device according to an embodiment of the present invention. 58, the display apparatus 100 includes a plurality of receiving units 110-1, 110-2,. . . 110-n, a plurality of signal processing units 120-1, 120-2,. . . 120-n, an output unit 130, a synchronization signal generation unit 140, an interface unit 150, and a control unit 160.

  The plurality of receiving units 110-1, 110-2,. . . 110-n, a plurality of signal processing units 120-1, 120-2,. . . , 120-n, the output unit 130, the synchronization signal generation unit 140, the interface unit 150, and the control unit 160 are the same as described above in addition to the content described separately below, The explanation is omitted as much as possible.

  The interface unit 150 communicates with the eyeglass device. In this case, the interface unit 150 can communicate with the glasses apparatus according to various wireless methods, transmit a synchronization signal to the glasses apparatus, and receive a content conversion command from the glasses apparatus.

  On the other hand, the interface unit 150 transmits / receives a Bluetooth device (Bluetooth device Address), a PIN code, and the like to the glasses device, and performs pairing according to the Bluetooth communication method. When the pairing is completed, the interface unit 150 can transmit a synchronization signal corresponding to any one of the plurality of contents to the glasses apparatus based on the information acquired through the payment.

  In addition, when pairing with a plurality of eyeglass devices is completed, the interface unit 150 can transmit synchronization signals that are the same or different from each other to different eyeglass devices based on information acquired through payment. The interface unit 150 can also transmit the same synchronization signal to some of the eyeglass devices. For example, the interface unit 150 may synchronize the first glasses device with the synchronization signal corresponding to the content 1, the second glasses device 2 with the synchronization signal corresponding to the content 2, and the third glasses device 3 with the synchronization corresponding to the content 1. A signal can be transmitted.

When a switching command is received from the glasses device synchronized with the first content, the control unit 160 sequentially arranges the video frame of the second content and the video frame of the third content at the position of the video frame of the first content. Thus, the output unit 130 can be controlled. In this case, the control unit 160 can control the interface unit 150 such that a synchronization signal for the display timing of the first content before the video frame arrangement pattern is changed is continuously transmitted to the glasses apparatus. Thereby, the user who wears the glasses device can view all the contents sequentially.

  On the other hand, when the content conversion command is received, the control unit 160 controls the interface unit 150 so as to transmit a synchronization signal corresponding to the other content among the plurality of contents to the glasses apparatus. The content can be processed so that the glasses apparatus is synchronized with other content.

  For example, when the interface unit 150 is implemented by a Bluetooth communication module, when the content conversion command is received, the control unit 160 sequentially transmits each of transmission packets including information on display timing of other content to the glasses device. The interface unit 150 can be controlled to transmit. The glasses apparatus opens / offs the shutter glass of the glasses apparatus based on the time information included in the sequentially received transmission packets. As a result, the user can view all the contents sequentially.

  The control unit 160 receives the selection command when the selection command is received via the interface unit 150 while the content corresponding to the glasses apparatus is sequentially converted to other content among the plurality of content. The conversion operation is completed so that the content at the time can be viewed through the glasses device.

  Specifically, the control unit 160 receives a selection command from the glasses device in the middle of changing the content arrangement pattern or changing the synchronization signal in order to sequentially convert the content synchronized with the glasses device. When the selection command is input, the glasses apparatus can be synchronized based on the content arrangement pattern or the synchronization signal.

  That is, the control unit 160 finishes changing the content arrangement pattern when the selection command is input, and alternately displays a plurality of contents based on the rearranged content arrangement pattern. Alternatively, the control unit 160 transmits a synchronization signal for content displayed at the time when the selection command is input to the glasses apparatus. As a result, the glasses apparatus is synchronized with the content displayed at the time when the selection command is input, and the user can view the desired content according to the selection command.

  Meanwhile, the conversion operation may be performed while the content conversion command is received from the glasses apparatus. That is, the control unit 160 can control the content conversion operation to be stopped when reception of the content conversion command is completed while performing the content conversion operation when the content conversion command is received.

  On the other hand, in the above-described embodiment, it has been described that the display device 100 generates each synchronization signal corresponding to the display timing of the content and transmits it to the glasses device 200, but this is merely an example.

  That is, the control unit 160 can control the interface unit 150 to generate a synchronization signal corresponding to the display timing of each content as one transmission packet according to the Bluetooth communication standard. That is, the interface unit 150 is synchronized with the display timing of the first content and is synchronized with the time information for opening / closing the shutter glass of the glasses device and the display timing of the second content, and the shutter of the glasses device. Time information for opening / closing the glass. . . , One transmission packet including all the time information for opening / closing the shutter glass of the glasses apparatus can be generated in synchronization with the display timing of the nth content.

  In this case, the interface unit 150 can generate a transmission packet by matching information for the glasses apparatus with the display timing of each content. For example, the interface unit 150 can match information for different glasses devices for each content according to the order in which the video frames of the content are arranged. That is, when two contents are provided in the multi-view mode (second mode), the first, third,. . . , The nth video frame of the content matches the information for the first glasses device, and the second, fourth,. . . , The video frame of the content arranged at the (n + 1) th time can match information for the second glasses apparatus (where n is an odd number). And the interface part 150 can transmit the transmission packet produced | generated so that the synchronization signal with respect to each of several content may be included to a spectacles apparatus. The eyeglass device can open / off the shutter glass using a synchronization signal including its own eyeglass device information among the synchronization signals for each of the plurality of contents.

  FIG. 59 is a block diagram for explaining the configuration of the eyeglass device according to the embodiment of the present invention. In particular, the eyeglass device 200 of FIG. 59 works in conjunction with the display device 100 that alternately displays a plurality of contents in units of video frames, and includes an input unit 210, a control unit 220, a shutter glass driving unit 230, an interface unit 240, a first shutter. A glass part 250 and a second shutter glass part 260 are provided.

  In addition to the contents described separately below for the components, the functions of the corresponding structures described above are performed, and therefore, the overlapping contents are not described as much as possible.

  The interface unit 240 performs communication from the display device. For example, the interface unit 240 may be implemented by a Bluetooth communication module, communicate with the display apparatus 100, receive a synchronization signal, and transmit a content conversion command to the display apparatus 100.

  As described above, the synchronization signal can be received in the form of a transmission packet in accordance with the Bluetooth communication standard, and is synchronized with the display timing of the content, so that the first shutter glass unit 250 and the second shutter of the glasses apparatus 200 are synchronized. Time information for opening or turning off the glass part 260 may be included.

  The input unit 210 receives a switching command for starting the switching mode. For this, the input unit 210 may include a switching button for receiving a switching command, and the switching button may be implemented by a touch sensor or an operation button.

  In addition, the input unit 210 receives a selection command for selecting one content while the content is sequentially switched in the switching mode. The input unit 210 may receive a selection command through a switching button that receives the switching command. For example, the input unit 210 may be embodied by receiving a switching command while the switching button is being touched, and receiving a selection command when the touch state of the switching button is finished when the touch state of the switching button is finished. Can do. The input unit 210 may have a separate selection button embodied by a touch sensor or an operation button.

  When the switching mode is started, the control unit 220 receives a synchronization signal corresponding to other contents that can be viewed among the plurality of contents, and receives the synchronization signal of the first shutter glass unit 250 and the second shutter glass unit 260. Control to change the open timing sequentially. For this, the control unit 220 controls the interface unit 240 so that a content conversion command for requesting a synchronization signal corresponding to another content is transmitted to the display apparatus 100 when the switching mode is started. To do.

  The display apparatus 100 that has received the content conversion command sequentially transmits to the glasses apparatus 200 each of the transmission packets including information on the display timing of other contents that can be viewed outside the content currently viewed by the user. The controller 220 can sequentially receive the synchronization signals corresponding to the other contents, and control the shutter glass driving unit 230 so that the drive signals are sequentially generated based on the synchronization signals corresponding to the respective contents. Accordingly, the first shutter glass unit 250 and the second shutter glass unit 260 are opened each time a video frame of each content is displayed. Thus, since the glasses apparatus is sequentially synchronized with each content, the user can view all the contents sequentially.

  On the other hand, when a selection command is input via the input unit 210 while the switching mode is being performed, the control unit 220 ends the switching mode and sets the display timing of content that can be viewed at the timing when the selection command is input. Accordingly, the shutter glass driving unit 230 is controlled to fix the open timing of the first shutter glass unit 250 and the second shutter glass unit 260.

  That is, when the selection command is input, the control unit 220 controls the interface unit 240 so that a command requesting to stop the content conversion operation is transmitted to the display apparatus 100. Then, the control unit 220 controls the shutter glass driving unit 230 so that the driving signal is generated based on the synchronization signal received from the display apparatus 100 at the time when the selection command is input. As a result, a user who has been viewing a plurality of contents sequentially can view a single content selected at the time when the selection command is input.

  Meanwhile, the switching command and the selection command may be input through one switching button as described above. In this case, the control unit 220 performs the switching mode while the switching button is touched. When the touch state of the switching button ends, the control unit 220 ends the switching mode, and the content that can be viewed when the touch state ends. The shutter glass driving unit 230 can be controlled to fix the open timings of the first shutter glass unit 250 and the second shutter glass unit 260 according to the display timing.

  That is, when the switching mode ends, the control unit 220 controls the shutter glass driving unit 230 so that a driving signal is generated based on the synchronization signal received at the time when the switching mode ends. As a result, a user who has been viewing a plurality of contents sequentially can view a single content selected when the touch state of the switching button ends.

  On the other hand, in the above-described embodiment, it has been described that the display device 100 generates each synchronization signal corresponding to the display timing of the content and transmits it to the glasses device 200, but this is merely an example. That is, the display apparatus 100 can generate a synchronization signal corresponding to the display timing of each content as a single transmission packet according to the Bluetooth communication standard and transmit it to the glasses apparatus.

  When the synchronization signal is received, the controller 220 can check the display timing corresponding to its own glasses apparatus information, and can open or turn off the shutter glass according to the confirmed display timing. When a switching command is input, the control unit 220 controls the shutter glass driving unit 230 so that a driving signal is sequentially generated based on a synchronization signal corresponding to each content included in the transmission packet. it can. Accordingly, the first shutter glass unit 250 and the second shutter glass unit 260 are sequentially opened each time the video frame of each content is displayed. Then, the controller 220 can select any one of the sequentially converted contents by controlling the generation of the drive signal based on the synchronization signal when the selection command is input.

  In the above-described embodiment, the display apparatus and the glasses apparatus communicate with each other according to various wireless communication schemes that can transmit and receive signals by forming a communication channel at a short distance. However, this is only an example. That is, the display device provides an IR synchronization signal having a different frequency to the glasses device, and the glasses device receives the synchronization signal having a specific frequency and applies the shutter glass according to the display timing of the corresponding content. Of course, it can be opened or turned off.

  FIG. 600 is a flowchart for explaining a content selection method according to an embodiment of the present invention. In particular, in the present embodiment, a description will be given of a content selection method of an eyeglass device that is linked to a display device that alternately displays a plurality of contents in units of video frames.

  First, the first and second shutter glass portions are driven (S6010). That is, the first and second shutter glass portions are driven according to the display timing of any one of the plurality of contents based on the synchronization signal received from the display device.

  Thereafter, when the switching mode is started (S6020-Y), the open timings of the first and second shutter glass portions are sequentially changed (S6030).

  Specifically, when the switching mode is started, a content conversion command for requesting a synchronization signal corresponding to another content can be transmitted to the display apparatus. When the switching mode is started, a synchronization signal corresponding to other contents that can be viewed among the plurality of contents is received, and the open timings of the first and second shutter glass portions are sequentially changed.

  That is, it opens each time a video frame of each content is displayed based on a synchronization signal corresponding to other content, and sequentially provides all the content to the user. Here, the switching mode can be started when a switching command is input through a switching button provided in the glasses apparatus.

  When the switching mode ends (S6040-Y), the content is synchronized with the selected content (S6050). Specifically, when any one of the sequentially converted contents is selected and the switching mode ends, the open timing of the first and second shutter glass portions can be maintained so that the selected contents can be viewed. . For this purpose, a selection command is received while the switching mode is being performed, and the opening timing of the first and second shutter glass portions according to the display timing of content that can be viewed at the timing when the switching mode is terminated and the selection command is input. To fix.

  In other words, the glasses apparatus can be synchronized with the selected content based on the synchronization signal corresponding to the display timing of the content provided to the user when the selection command is input. As a result, a user who has been viewing a plurality of contents sequentially can view a single content selected at the time when the selection command is input. In this case, the switching mode is performed while the switching button is being touched, and can be ended when the touch state of the switching button is released.

  FIG. 61 is a flowchart for explaining a content conversion method according to an embodiment of the present invention. In particular, in the present embodiment, a content conversion method in a display device will be described.

  First, a plurality of contents are combined and displayed (S6110). Specifically, a plurality of different contents are alternately arranged and displayed for each video frame. In this case, video data can be separated from a plurality of contents, and processing such as decoding, scaling, and frame rate conversion on the video data can be performed. Since the specific operation has been described above, redundant description is omitted.

  Thereafter, a synchronization signal is transmitted (S6120). Specifically, a synchronization signal for synchronizing the glasses device corresponding to each content is transmitted according to the display timing of each content.

  When a content conversion command is received from the glasses device (S6130-Y), a content conversion operation is performed (S6140). Specifically, when a content conversion command is received, a conversion operation is performed in which the content corresponding to the glasses device is converted to another content among the plurality of content.

  Specifically, when the content conversion command is received, the content arrangement pattern can be changed so that the frame of another content is positioned at the frame position of the content corresponding to the glasses apparatus. On the other hand, when the content conversion command is received, the synchronization signal corresponding to the other content among the plurality of contents is transmitted to the glasses apparatus, and the glasses apparatus synchronizes with the other contents among the plurality of contents. Can be processed. Since each of these embodiments has been described above, a duplicate description is omitted.

  When the conversion operation ends (S6150-Y), the conversion operation ends (S6160). That is, when any one of the plurality of contents is selected, the conversion operation is terminated. Specifically, when a selection command is received from the glasses device while the content corresponding to the glasses device is sequentially converted to other content among the plurality of contents, the content at the time when the selection command is received is displayed as glasses. The conversion operation is completed so that the user can view the video through the device.

  In this case, the conversion operation may be performed while the switching command is received from the glasses apparatus. That is, it is possible to perform control so that the content conversion operation is performed when the switching command is received, and the content conversion operation is stopped when reception of the switching command is completed.

  Since each of these embodiments has been described above, redundant description and illustration are omitted.

  Meanwhile, a program for performing the method according to various embodiments of the present invention described above can be stored and used in various types of recording media.

  Specifically, the code for performing the above-described method is a RAM, a flash memory, a ROM, an EPROM, an EEPROM, a register, a hard disk, a removable disk, a memory card, a USB memory, a CD-ROM, etc. It can be stored in various types of readable recording media.
