In this case, the spectacle device 1 200-1 opens both the left shutter glass and the right shutter glass when one content A is displayed according to the synchronization signal, and the left shutter when the other content B is displayed. It may be operable to turn off both the glass and the right shutter glass. Accordingly, viewer 1 wearing eyeglass device 1 200-1 synchronizes one content (synchronized with eyeglass device 1 200-1) among a plurality of contents A and B that are alternately displayed. A) You can watch only. In the same manner, viewer 2 wearing the spectacles 2 200-2 may watch the content B only. The alternating display of image frames for different content is achieved at a very high speed, and the afterimage effect of the retina persists while the lens is closed, making the image appear natural to the user.

2 is a view for explaining a method of providing a plurality of 3D content according to an embodiment of the present invention.

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

For example, the left eye image and the right eye images AL and AR of the 3D content A may be displayed, and the left eye image and the right eye images BL and BR of the 3D content B may be alternately displayed. In this case, the eyeglass device 1 200-1 opens the left eye and the right eye glass at the display time point of the left eye image and the right eye image AL and AR of the 3D content A, and the eyeglass device 2 200-2 the 3D content B. The left eye and right eye glasses may be opened at the display time point of the left eye image and the right eye image BL and BR.

Accordingly, viewer 1 wearing the eyeglass device 1 200-1 views only the 3D content A, and viewer 2 wearing the eyeglass device 2 200-2 views the 3D content B only. You will watch.

However, this is a description of a case in which the shutter glass method is assumed, and in the case of the polarization method, the polarization direction of each of the plurality of content images and the polarization directions of the spectacles 1 and 2 may be implemented to support the multi-view mode. It will be apparent to those skilled in the art.

3 and 4 are diagrams for describing a synchronization signal transmission method according to various embodiments of the present disclosure.

According to FIG. 3, the display apparatus 100 may broadcast or multicast a single signal muxed with a synchronization signal corresponding to the spectacle apparatus 1 200-1 and the spectacle apparatus 2 200-2. The spectacle apparatuses 200-1 and 200-2 may operate to turn on / off the shutter glass in synchronization with a synchronization signal corresponding to a user command (eg, a channel switching command) among the corresponding signals.

However, the above-described embodiment is merely an example, and as shown in FIG. 4, the display apparatus 100 may provide a synchronization signal corresponding to the eyeglass apparatus 1 200-1 and the eyeglass apparatus 2 200-2. Each of the corresponding glasses apparatuses 200-1 and 200-2 may be unicasted, and the glasses apparatuses 200-1 and 200-2 may receive a corresponding synchronization signal.

Meanwhile, the synchronization signal may be implemented in the form of an RF (Radio Fequency) signal or an Infra Red (IR) signal, which will be described later.

5 is a block diagram illustrating a configuration of a display apparatus according to various embodiments of the present disclosure.

Referring to FIG. 5, the display apparatus 100 includes a plurality of receivers 110-1, 110-2,..., 110-n, and a plurality of signal processors 120-1, 120-2,. n), a display unit 130, a synchronization signal generator 140, an interface unit 150, and a controller 160.

The plurality of receivers 110-1, 110-2,..., 110-n receive different contents, respectively. In detail, each receiver 110-1, 110-2,..., 110-n stores contents from a broadcasting station transmitting broadcast program content using a broadcast network or a web server transmitting content files using the Internet. Receive. It is also possible to receive content from various recording medium playback apparatuses provided in the display apparatus 100 or connected to the display apparatus 100. [ The recording medium playback device refers to a device that plays back content stored in various types of recording media such as CD, DVD, hard disk, Blu-ray disk, memory card, USB memory,

In an embodiment of receiving content from a broadcasting station, the plurality of receivers 110-1, 110-2,..., 110-n may include a tuner (not shown), a demodulator (not shown), and an equalizer (not shown). It may be implemented in a form including a configuration such as. In contrast, in an embodiment of receiving content from a source such as a web server, the plurality of receivers 110-1, 110-2,..., 110-n may be implemented as a network interface card (not shown). . Alternatively, in the case of receiving the contents from the various recording medium reproducing apparatuses described above, the plurality of receiving units 110-1, 110-2,..., 110-n may include an interface unit (not shown) connected to the recording medium reproducing apparatus. May be implemented. For example, an AV terminal, a COMP terminal, and an HDMI terminal.

As such, the plurality of receivers 110-1, 110-2,..., 110-n may be implemented in various forms according to embodiments.

In addition, the plurality of receivers 110-1, 110-2,..., 110-n may not necessarily receive content from the same type of source, but may also receive content from different types of sources.

The plurality of signal processing units 130-1, 130-2,..., And 130-n respectively receive content received from the plurality of receivers 110-1, 110-2,..., 110-n. Various signal processing can be performed.

In particular, the plurality of signal processing units 130-1, 130-2,..., 130-n process each received image in the form of an image frame, and perform luminance adjustment processing for each of the plurality of contents processed in the form of a frame. Can be done.

Meanwhile, according to various embodiments of the present disclosure, the display apparatus 100 may further include a mux unit (not shown) for multiplexing image frames. The MUX unit 170 may multiplex and output the image frames such that the image frame of the first content, the image frame of the second content, ..., and the image frame of the n-th content are alternately arranged one by one.

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

The display 130 outputs one content view in the single view mode and combines and outputs the plurality of content views in the multi view mode.

The display unit 130 may include a liquid crystal display panel, a plasma display panel, organic light emitting diodes (OLED), a vacuum fluorescence display (VFD), a field emission display (FED), and an ELD ( Electro Luminescence Display) and the like. The display unit 130 may be implemented in the form of a display unit as described below.

As described above, a mode of alternately arranging image frames of each content and displaying the same may be referred to as a multi view mode (or a dual view mode). When the display apparatus 100 operates in a normal mode (or a single view mode) displaying only one 2D content or 3D content, only one of the plurality of receivers 110-1, 110-2,..., 110-n is displayed. Can be activated to process content. When the user selects the multi-view mode while operating in the normal mode, the display apparatus 100 may activate the remaining receiver to process data in the above-described manner.

Meanwhile, the above-described content may be 2D content or 3D content. 3D content refers to content that allows a user to feel three-dimensional by using a multi-view image in which the same object is expressed from different perspectives.

When using a plurality of 3D contents, the display unit 130 includes a left eye image and a right eye included in each 3D content provided by the plurality of frame rate converters 122-1, 122-2, ..., 122-n. Images may be multiplexed in a predetermined arrangement and alternately arranged with image frames of other contents.

Accordingly, the left eye image, the right eye image of the first content, the left eye image of the second content, the right eye image, the left eye image of the n-th content, and the right eye image are sequentially arranged and displayed, and the user displays the eyeglasses 200. Through this, the left eye image and the right eye image of one content are recognized.

Meanwhile, the display apparatus 100 further includes a configuration for differently providing audio data included in each content for each user when operating in the multi-view mode. That is, a demultiplexer (not shown) for separating video data and audio data from content received at each receiver 110-1, 110-2,..., 110-n, and an audio decoder for decoding the separated audio data. (Not shown), a modulator (not shown) for modulating the decoded audio data into different frequency signals, a display unit (not shown) for transmitting the modulated audio data to the spectacles, and the like. Each audio data output from the display unit 130 is provided to the user through output means such as earphones provided in the spectacles. Since these configurations are not directly related to the present invention, a separate illustration is omitted.

In some cases, if the content includes additional information such as an EPG (Electronic Program Guide) and subtitles, the demultiplexer may further separate the additional data from the content. In addition, the display apparatus 100 may add a subtitle or the like processed to be displayed through an additional data processor (not shown) to the corresponding image frame.

The synchronization signal generator 140 generates a synchronization signal for synchronizing the glasses device corresponding to each content according to the display timing of each content. That is, the synchronization signal generator 140 generates a synchronization signal for synchronizing the spectacles with the display timing of the image frame for the content in the multi-view mode.

The interface unit 150 transmits a synchronization signal to the spectacles. In this case, the interface unit 150 may transmit the synchronization signal to the spectacles device in various ways.

For example, the interface unit 150 may include an RF communication module to communicate with the spectacles. Herein, the RF communication module may be implemented as a Bluetooth communication module. Accordingly, the interface unit 150 may generate a transmission stream according to the Bluetooth communication standard so as to include a synchronization signal and transmit the generated stream to the spectacles.

That is, the transport stream includes time information for turning on / off the shutter glass of the spectacle device in synchronization with the display timing of each content. Specifically, the transport stream includes an offset time for turning on the left eye shutter glass of the spectacle apparatus, an offset time for turning off the left eye shutter glass, an offset time for turning on the right eye shutter glass, and a right eye shutter glass from a reference time point set for each content. It may include information about the offset time to turn off. Here, the reference time point is a time point at which the vertical sync signal is generated in the image frame of each content, and time information on the time point at which the vertical sync signal is generated may also be included in the transport stream.

In order to perform communication according to the Bluetooth communication method, the interface unit 150 performs pairing with each eyeglass device. When pairing is completed, information about each eyeglass device, for example, a device ID (or address), may be registered in the interface unit 150. The interface unit 150 matches a display timing of each content with information about the glasses device and generates one transport stream according to the Bluetooth communication standard. For example, the interface unit 150 may match information about different glasses devices for each content in the order in which the image frames of the content are arranged. That is, when two contents are alternately provided in the multi-view mode, the image frames of the first, third, ..., n-th placed images match the information about the first glasses device, and the second For example, the fourth,..., N + 1 th image frame may match information about the second eyeglass device (where n is odd). The eyeglasses may check the display timing corresponding to the eyeglass apparatus information when the synchronization signal is received, and turn the shutter glass on or off according to the confirmed display timing.

Although the above-described embodiment has been described as the interface unit 150 and the spectacle device performing communication according to the Bluetooth communication method, this is only an example. That is, in addition to the Bluetooth method, it is possible to use a communication method such as infrared communication, Zigbee, etc., and to perform communication according to various wireless communication methods capable of transmitting and receiving signals by forming a communication channel in other local areas. .

The interface unit 150 may provide an IR (Infra Red) synchronization signal having a different frequency to the spectacle device. In this case, the spectacle apparatus may receive a synchronization signal having a specific frequency and turn on or off the shutter glass according to the display timing of the corresponding content.

In this case, the interface unit 150 glasses the infrared signal in which the high level during the first period and the low level during the second period are alternately repeated at predetermined time intervals based on the synchronization information. Can be sent to the device. The spectacle device may be implemented to turn on the shutter glass during the first period at the high level and to turn off the shutter glass during the second period at the low level. In addition, the synchronization signal may be generated in various ways.

The controller 160 controls operations of the first half of the display apparatus 100. Specifically, the controller 160 includes a plurality of receivers 110-1, 110-2,..., 110-n, and a plurality of signal processors 130-1, 130-2,..., 130-n. Each control unit may be controlled to perform a corresponding operation by controlling each of the MUX unit (not shown), the display unit 130, the synchronization signal generator 140, and the interface unit 150. On the other hand, since the operation performed by each configuration of the display apparatus 100 has been described above, duplicate description thereof will be omitted.

6 is a block diagram showing the configuration of the signal processor 130.

Referring to FIG. 6, the arbitrary signal processor 120-1 may include a video processor 121-1 and a frame rate converter 122-1.

The video processor 121-1 performs signal processing on video data included in the received content. In detail, the video processor 121-1 may include a decoder (not shown) that performs decoding on video data, and a scaler (not shown) that performs up or down scaling in accordance with the screen size of the display 130. Can be.

In addition, the video processor 121-1 may convert the video data into a data format corresponding to the frame rate converter 122-1. For example, image frames of respective contents may be connected in a horizontal direction to be converted into a side-by-side format.

The frame rate converter 122-1 converts the frame rate of the content provided from the video processor 121-1 to match the multi-content display rate with reference to the output rate of the display apparatus 100. In detail, when the display apparatus 100 operates at 60 Hz, the frame rate converter 122-1 may convert the frame rate of each content to n × 60 Hz.

The communication interface unit 150 may receive a content confirmation command corresponding to the other glasses device. That is, the communication interface unit 150 may receive a content confirmation command for content that is not synchronized with the glasses device from the glasses device.

For example, when the glasses device 1 is synchronized to the content A, and the glasses device 2 is synchronized to the content B, the communication interface unit 150 may output the content for the content B that is not synchronized with the glasses device 1. A confirmation command can be received from the spectacle device 1. Similarly, the communication interface unit 150 may receive a content confirmation command for the content A from the glasses device 2.

The controller 160 controls the operation of the first half of the display apparatus 100 as described above. In particular, when a content confirmation command corresponding to the other eyeglasses is input, the controller 160 may display content information corresponding to the other eyeglasses at a display timing corresponding to the eyeglasses. Here, the content information corresponding to the other eyeglasses may include at least one of a content title corresponding to the other eyeglasses, a channel for providing content corresponding to the other eyeglasses, and a screen constituting content corresponding to the other eyeglasses. can do.

In detail, when a content confirmation command is input, the controller 160 may display content information corresponding to another eyeglass device overlapping with content corresponding to the eyeglass device.

That is, the controller 160 may display information on the content not synchronized with the eyeglasses device in one region of the screen where the content synchronized with the eyeglasses device is displayed. For example, the controller 160 configures a content A synchronized with the spectacle device and a content B not synchronized with the spectacle device as a picture in picture (PIP) screen to display display timing of the synchronized content with the spectacle device. Can be displayed on the screen.

On the other hand, when a content confirmation command is input, the controller 160 arranges an image frame including content information corresponding to another eyeglass apparatus at the display timing of the content corresponding to the eyeglass apparatus.

That is, the controller 160 generates the content information of the content which is not synchronized with the eyeglass apparatus which has transmitted the content confirmation command as an image frame, and arranges the image frame for the content information at the display timing of the content synchronized with the eyeglass apparatus. Can be displayed. For example, the controller 160 may arrange the image frame constituting the content B which is not synchronized with the spectacle device at the display timing of the content A synchronized with the spectacle device.

According to various embodiments as described above, the viewer wearing the eyeglasses can check the information on the content synchronized with the other eyeglasses.

Meanwhile, in the above-described embodiment, the image frame constituting the other content is described as being displayed at the display timing of the content synchronized with the spectacle device, but this is merely an example. That is, the controller 160 generates content titles of other contents extracted based on the EPG information, information on channels provided with other contents in the form of OSD (On Screen Display), and displays contents synchronized with the eyeglasses device. Of course, it can be controlled to be displayed at the timing.

When the content confirmation command is input, the controller 160 may display a message inquiring whether to provide content information corresponding to the other eyeglasses at the display timing of the content corresponding to the other eyeglasses. That is, the controller 160 generates a message inquiring whether to display the information on the content synchronized with the other eyeglasses device at the display timing of the content synchronized with the eyeglasses device, and displays the content synchronized with the other eyeglasses device. Can be displayed superimposed.

The controller 160 may display the content information corresponding to the other eyeglasses at the display timing of the content corresponding to the other eyeglasses when the user command to agree to provide the content information corresponding to the other eyeglasses is input. That is, if the user who wears the other eyeglasses agrees to provide the other user (ie, the user who wears the eyeglasses) with the information about the content viewed by the user wearing the other eyeglasses, the controller 160 Information about the content may be provided.

For example, assume that the spectacle device 1 is synchronized to the content A, and the spectacle device 2 is synchronized to the content B. In this case, when a content confirmation command is input from the spectacle device 1, the controller 160 may display a message inquiring whether to provide the information about the content B and overlapping the content B in the OSD form. Subsequently, when a command for agreeing to provide the information about the content B is input from the user wearing the spectacles 2, the controller 160 displays the information about the content B at the display timing of the content A. FIG. Can be. In this case, as described above, the controller 160 may display the information about the content B by overlapping the content A or display only the information about the content B at the display timing of the content A. FIG.

Meanwhile, in the above-described embodiment, the configuration for generating the synchronization signal and the configuration for transmitting the synchronization signal are described as separate, but for convenience of description. That is, the interface unit 150 may generate a synchronization signal and transmit the synchronization signal to the eyeglass device. In this case, the synchronization signal generator 140 may be omitted.

Meanwhile, in the above-described embodiment, the display apparatus 100 generates synchronization signals corresponding to the display timing of the contents, and transmits them to the glasses apparatus 200. However, this is merely an example.

That is, the controller 160 may control the interface unit 150 to generate a synchronization signal corresponding to the display timing of each content as one transport packet according to the Bluetooth communication standard. That is, the interface unit 150 synchronizes the display timing of the first content to open / off the shutter glass of the spectacles device, and synchronizes the display of the second content to open / off the shutter glasses of the spectacles device. Time information, ..., and one transmission packet including all the time information for opening / off the shutter glass of the spectacle device in synchronization with the display timing of the n-th content.

In this case, the interface unit 150 may generate a transport packet by matching the information on the spectacles with the display timing of each content. For example, the interface unit 150 may match information about different glasses devices for each content in the order in which the image frames of the content are arranged. That is, when two pieces of content are provided in the multi-view mode, the image frames of the first, third, ..., n-th placed images match information about the spectacle device 1, and the second, fourth, ...., the image frame of the content placed in the n + 1 th can match the information for the eyeglasses device 2 (where n is odd). In addition, the interface unit 150 may transmit a transmission packet generated to include a synchronization signal for each of the plurality of contents to the spectacles. The spectacle device may open / off the shutter glass by using a synchronization signal including its spectacle device information among the synchronization signals for each of the plurality of contents.

In another embodiment, the user interface 170 of FIG. 8 may receive a content confirmation command. The content confirmation command refers to a user command input from a user wearing the eyeglasses device in order to confirm contents synchronized with other eyeglasses. To this end, the user interface unit 170 may be implemented as a touch pad, a key button, a keypad, or the like, or may be implemented to receive a user command input from a remote controller (not shown) such as a remote controller. In addition to the content confirmation command, the user interface unit 170 may receive various user commands for controlling the display apparatus 100 such as a channel selection command and a volume adjustment command. That is, the present embodiment differs from FIG. 5 only in that the content confirmation command is received from a separate user interface unit 170, not the glasses device.

9 is a block diagram illustrating a configuration of an eyeglass device according to an embodiment of the present invention. According to FIG. 9, the spectacles 200 may include a communication interface 210, a controller 220, a shutter glass driver 230, a first shutter glass unit 250, a second shutter glass unit 260, and an input unit ( 240).

The basic function of each component is as described above, and overlapping content is omitted if possible.

The communication interface 210 communicates with the display device. For example, the communication interface 210 may be implemented as a Bluetooth communication module to communicate with the display apparatus 100 to receive a synchronization signal and transmit a content confirmation command.

As described above, the synchronization signal may be received in the form of a transmission packet according to the Bluetooth communication standard, and synchronized to the display timing of the content, the first shutter glass unit 250 and the second shutter glass unit ( 260 may include time information for opening or turning off. Since the information included in the transport packet has been described above with reference to FIG. 5, the redundant description is omitted.

The input unit 240 receives a user command for transmitting a content confirmation command to the display device. To this end, the input unit 240 may be implemented as a touch sensor or an operation button for receiving a user command. In this way, a user wearing the spectacles 200 may request a display device to display information about contents synchronized with other spectacles.

When a user command is input through the input unit 240, the controller 220 controls the communication interface 210 to transmit a content confirmation command to the display apparatus.

For example, the controller 220 may transmit a content confirmation command to the display device along with the information about the glasses device 200 such as a Bluetooth address, a device ID, and the like. Accordingly, the display apparatus checks the contents synchronized with the spectacles device which has transmitted the content confirmation command based on the spectacles device information, and displays the information about the contents synchronized with the other spectacles with the display timing of the contents synchronized with the spectacles. can do.

Meanwhile, in the above-described embodiment, the display apparatus 100 generates synchronization signals corresponding to the display timing of the contents, and transmits them to the glasses apparatus 200. However, this is merely an example. That is, the display apparatus 100 may generate a synchronization signal corresponding to the display timing of each content as one transport packet according to the Bluetooth communication standard and transmit the synchronization signal to the spectacles device.

When the synchronization signal is received, the controller 220 may check a display timing corresponding to the glasses device information and open or turn off the shutter glass according to the confirmed display timing.

In addition, in the above-described embodiment, the display apparatus and the eyeglass apparatus communicate with each other according to various wireless communication methods capable of transmitting and receiving signals by forming a communication channel at a short distance, but this is merely an example. That is, the display device provides an IR (Infra Red) synchronization signal having a different frequency to the glasses device, the glasses device receives a synchronization signal having a specific frequency, and open or off the shutter glass in accordance with the display timing of the corresponding content Of course you can.

10 to 13 are diagrams for describing an operation when a content confirmation command is input according to an embodiment of the present invention. In particular, the glasses device 1 and 2 (not shown) are synchronized with the display device 300, respectively, in each drawing, (1) shows a screen viewed by a user 1 wearing the glasses device 1, and (2) is a glasses device. A screen viewed by the user 2 wearing 2 is displayed.

As shown in FIG. 10, the user 1 views a content 310 synchronized with the eyeglasses device 1 400-1 among a plurality of contents 310 and 320 alternately displayed on the display device 300. User 2 watches the content 320 synchronized with glasses device 2 400-2.

Subsequently, when a content confirmation command is received from the glasses device 1 or the remote controller (not shown) requesting display of information about the content 320 which is not synchronized with the glasses device 1400-1, the device illustrated in FIG. As described above, the display apparatus 300 provides a message 330 inquiring whether the user 2 should provide information about the content 320. In this case, since the message 330 is provided in an OSD form so as to overlap with the content 320, only the user 2 wearing the spectacle device 2 400-2 may be recognized.

Subsequently, when a command for agreeing to provide information about the content 320 is input from the user 2, the display apparatus 300 displays the information about the content 320 at the display timing of the content 310.

For example, as illustrated in FIG. 12, the display apparatus 300 configures an image frame for the content 310 and an image frame for the content 320 in the form of PIP, and displays the content timing of the content 310. Can be displayed. Alternatively, as shown in FIG. 13, the display apparatus 300 may arrange and display the content 320 at the display timing of the content 310. Accordingly, the user 1 can check the information about the content 320.

14 is a flowchart illustrating a multi-view providing method according to an exemplary embodiment. In particular, FIG. 14 illustrates a multi-view providing method in the display device.

First, a plurality of different contents are displayed (S1410). In detail, a plurality of different contents may be alternately arranged and displayed in units of image frames.

Thereafter, the synchronization signal is transmitted (S1420). Specifically, according to the display timing of each content, a synchronization signal for synchronizing the spectacles device corresponding to each content is transmitted.

A content confirmation command corresponding to the other eyeglasses is received (S1430). When a content confirmation command corresponding to the other eyeglasses is received (S1430-Y), content information corresponding to the other eyeglasses is displayed (S1440). Specifically, the content information corresponding to the other eyeglasses may be displayed on the display timing of the content corresponding to the eyeglasses. Here, the content information corresponding to the other eyeglasses may include at least one of a content title corresponding to the other eyeglasses, a channel for providing content corresponding to the other eyeglasses, and a screen constituting content corresponding to the other eyeglasses. can do.

Meanwhile, in displaying content information, when a content confirmation command is input, information about content corresponding to another glasses autonomous may be displayed overlapping with content corresponding to the spectacle device. Alternatively, when a content confirmation command is input, an image frame including information about content corresponding to the other glasses device may be arranged at the display timing of the content corresponding to the glasses device. Since these embodiments have been described above, overlapping description and illustration are omitted.

On the other hand, if a content confirmation command is input, a message inquiring whether to provide information on the content corresponding to the other eyeglasses may be displayed on the display timing of the content corresponding to the eyeglasses. Accordingly, when a user command to agree to provide the content information corresponding to the other eyeglasses is input, information about the content corresponding to the other eyeglasses may be displayed on the display timing of the content corresponding to the eyeglasses.

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

Specifically, the code for performing the above-described methods may be stored in a storage medium such as a RAM (Random Access Memory), a FLASH memory, a ROM (Read Only Memory), an EPROM (Erasable Programmable ROM), an EEPROM (Electronically Erasable and Programmable ROM) Such as a floppy disk, a removable disk, a memory card, a USB memory, a CD-ROM, and the like.

which contents In view For other eyewear device Matching Restrictive Embodiment

Hereinafter, an embodiment of restricting matching of other eyeglasses to any content view among a plurality of content views according to various embodiments of the present disclosure will be described.

15 is a conceptual diagram illustrating a problem when one content view is shared in the display apparatus 100.

Here, the contents view refers to a display screen and a sound synchronized with the one eyeglass apparatus 200 synchronized with the display apparatus 100. Although various types of content can be viewed through one content view, the two contents are distinguished in that one content can be viewed only through the same content view.

On the other hand, in principle, one content view may be shared by various eyeglasses 200. For example, a plurality of users, each wearing glasses, may watch a sporting event together through the same content view. However, depending on the nature of the content, it is necessary to give priority to the occupancy of the content view or to limit the sharing of the content view. 15 shows such an example. 15 illustrates a situation where two users are playing video games through different content views. When two users become opponents of a video game, it is necessary to restrict the sharing of content views among them even for the interest of the game.

Hereinafter, a detailed configuration and operation of the display apparatus 100 and the spectacles 200 according to an exemplary embodiment of the present disclosure will be described in detail.

According to various embodiments of the present disclosure, the display apparatus 100 may include a receiver 110 that receives content, a signal processor 120 that processes the received content, and a signal process as illustrated in FIG. 5. The display unit 130 for outputting the contents, the synchronization signal generator 140 for generating a synchronization signal, the interface unit 150 for communicating with the spectacles 200, and the storage unit 190 for storing control operation information. And a controller 160 for controlling the display apparatus 100.

As described above in the respective components, overlapping portions are omitted wherever possible, and hereinafter, description will be made based on the contents related to the present embodiment.

The control unit 160 will be described below. The controller 160 controls the overall operation of the display apparatus 100 according to an exemplary embodiment. In particular, when a sharing limit command is input to one of the plurality of content views, matching of other eyeglasses to the content view is restricted. The sharing limit command is a command for prohibiting matching of the spectacle device with respect to a certain content view. When the sharing limit command is executed, the corresponding content view becomes inaccessible to another spectacle device. For example, in the above-described video game of FIG. 15, when a sharing limit command is input from the glasses device matched with the content view of user 1, all other glasses devices cannot access the content view of user 1. Similarly, when a sharing restriction command is input from the glasses device matched with the content view of the user 2, all other glasses devices including the glasses device matched with the content view of the user 1 cannot access the content view of the user 2.

In some cases, a user may want to restrict sharing of the content view that he or she views only to a specific user. In this case, instead of a sharing restriction command for prohibiting matching of all eyeglasses with respect to a specific content view, an optional sharing restriction command for prohibiting matching of specific eyeglasses may be input. For example, a user may not want to show a movie he is watching to friend A or friend B but only to friend C. In this case, an optional sharing restriction command may be input to prohibit matching of the glasses device worn by the friend C. The controller 160 prohibits matching of the selected spectacle device when a selective sharing restriction command for prohibiting matching of a specific spectacle device with respect to a content view is input.

Due to the nature of the content, there may be content in which sharing restriction setting is prohibited. For example, the display apparatus 100 and the spectacles 200 may be used for education. In this case, the student glasses device 200 is matched to the student content view in which the correct answer of the problem is not displayed and should not match the teacher content view in which the correct answer of the problem is displayed. Therefore, a sharing restriction command may be input to the teacher content view, and the student glasses device may not match the teacher content view. On the other hand, the teacher should be able to view the student content view to explain the content displayed to the student, the teacher glasses device should be allowed to access the student content view. Therefore, even if a sharing limit command for the student content view is input, the sharing limit setting should not be made. As a result, the controller 160 allows the teacher glasses device to match the student content view even when the sharing restriction command is input.

If there is a sharing restriction setting, the operation of the controller 160 may also vary. First, as described above, the content view with the sharing restriction setting is prohibited from matching with other eyeglasses 200. In addition, when the content view in which the sharing limit command is input is selected by the other glasses device 200, the other glasses device 200 may match another content view. In this case, there is a method of matching with a similar content view in consideration of the nature of the content view that another spectacle device is trying to match. For example, if an attempt is made to match a content view about a movie, the user may select and match among other content views related to the movie.

When a sharing restriction release command for a specific content view is input, the controller 160 allows matching of other eyeglasses to the content view. In the above-described embodiment in which the present invention is used for education, students wearing the student glasses device must first solve the problem through the student content view, and see the display screen including the correct answer through the teacher content view. Therefore, when the sharing restriction release command for the teacher content view is input, the student glasses device can be matched with the teacher content view, and the students wearing the glasses device can see the display screen including the correct answer.

Meanwhile, the input of the sharing limit command or the sharing limit release command may be made in various ways. As an example, the spectacle apparatus 200 may receive a sharing restriction or sharing restriction release command through the input unit 240 described above, and transmit the same to the display apparatus 100 through the interface unit 210. The interface unit 150 of the display apparatus 100 receives a sharing restriction or a sharing restriction release command. In addition, the command may be transmitted through a remote controller (not shown), or the command may be directly input through a key (not shown) provided in the main body of the display apparatus 100.

Hereinafter, a method of controlling the display apparatus 100 according to an exemplary embodiment will be described with reference to FIGS. 16 and 17. Since the operation of the specific configuration has been described above, the overall operation will be described schematically here.

16 is a flowchart illustrating a control method of the display apparatus 100 according to the present embodiment, and FIG. 17 is a flowchart illustrating a control method of the display apparatus 100 according to another embodiment of the present invention.

The display apparatus receives a plurality of contents (S1610 and S1705), and processes a plurality of contents to form an image frame (S1620 and S1710). Thereafter, the plurality of content views are output by combining the image frames of the respective contents (S1630 and S1715), and a synchronization signal for synchronizing the plurality of content views and the plurality of eyeglasses 200 is generated (S1640 and S1720). Then, the synchronization signal is transmitted to the plurality of spectacles (S1650, S1725). When a sharing restriction command is input in such a situation that a plurality of content views are output (S1660-Y and S1730-Y), it is determined whether the sharing restriction setting is prohibited (S1735). If the sharing restriction setting is allowed (S1735-N), matching of other glasses with respect to the content view is restricted (S1740). Alternatively, another content view may be matched (S1745). However, if the sharing restriction setting is prohibited (S1735-Y), the matching of other eyeglasses with respect to the content view should be allowed (S1755). When the sharing restriction release command is input (S1750-Y), the matching of other eyeglasses with respect to the content view is allowed (S1670, S1755).

18 is a block diagram illustrating a configuration of an eyeglass device 200 according to various embodiments of the present disclosure. In particular, the spectacle apparatus 200 of FIG. 18 is interlocked with the display apparatus 100 that alternately outputs a plurality of contents in units of image frames, and includes an input unit 240, a controller 220, a shutter glass driver 230, The communication interface unit 210 includes a first shutter glass unit 250 and a second shutter glass unit 260.

Since the above descriptions are the same as those described above except for the descriptions below, redundant descriptions will be omitted.

The input unit 240 is configured to receive a sharing limit command, an optional sharing limit command, or a sharing restriction release command. The input unit 240 of the spectacle device that matches one of the plurality of content views receives a sharing limit command or an optional sharing limit command, and the interface unit 210 transmits the content to the display device 100. In the case of the sharing restriction command, the matching of the other glasses device 200 with respect to the corresponding content view is prohibited. On the other hand, in the case of the selective sharing restriction command, the matching of the selected glasses device 200 with respect to the corresponding content view is prohibited. When the sharing restriction release command is input to the input unit 240 of the eyeglass device matched to the content limit subject to the sharing restriction or the selective sharing restriction, the interface unit 210 transmits the command to the display apparatus 100 and the content view. The sharing limit for the is released.

The interface unit 210 performs communication from the display apparatus 100. The communication interface 210 is implemented as a Bluetooth communication module to communicate with the display apparatus 100 to receive a synchronization signal, and as described above, a response to the control command and the control command agreement with respect to the display apparatus 100. Receive the input. In addition, as described above, the sharing limit command, the selective sharing limit command, or the sharing restriction release command input through the input unit 24 may be transmitted to the display apparatus 100.

As described above, the synchronization signal may be received in the form of a transport stream according to the Bluetooth communication standard, and synchronized to the display timing of the content, the first shutter glass unit 250 and the second shutter glass unit ( 260 may include time information for turning on or off. Since the information included in the transport stream has been described above, the redundant description is omitted.

Hereinafter, a polarization method will be described with reference to FIG. 19 as another embodiment of the present invention. 19 is a conceptual diagram illustrating a situation of viewing an image with a spectacle device having a polarizing lens for each case when image frames of contents polarized in a horizontal direction and a vertical direction are alternately displayed.

The display apparatus 100 may further include a polarizing member (not shown). The polarizing member (not shown) may include a liquid crystal layer (not shown) to polarize the image. The display apparatus 100 controls the liquid crystal layer for each horizontal line or vertical line by using driving voltages having different levels, and polarizes an image of the content emitted from the display apparatus 100 in a specific direction. At this time, the image of the polarized content may be alternately arranged and output. For example, one content may be polarized in a horizontal direction to be output, and then another content may be polarized in a vertical direction to be output, and the process may be repeated. Each image, that is, a content view, can be viewed through the spectacle apparatus 200-3 having the horizontal polarizing lens and the spectacle apparatus 200-4 having the vertical polarizing lens. In another embodiment, image information of different contents may be included in different regions of one image frame. In this case, each area may be polarized and output in a different direction, and different content views may be viewed through a spectacle device having a lens corresponding to each polarization direction.

In this case, the spectacles 200-3 and 200-4 used to view the display apparatus 100 may include polarized lenses that match the polarization direction of the content to be viewed. As a result, each eyeglass device passes only the polarized image, so that the user can watch only the desired content view. Since the glasses 200-3 and 200-4 do not need a separate synchronization operation with the display apparatus 100, the economical efficiency is high and the flicker occurring in the synchronization process is also reduced. FIG. 19 illustrates a case in which a content view is viewed with the spectacle apparatus 200-3 or 200-4 with polarizing lenses suitable for the case where image frames of contents polarized in the horizontal direction and the vertical direction are displayed alternately. It is shown.

The present invention includes the configuration described so far, by restricting or releasing the matching of the content view and the eyeglass device if necessary, it is possible to create a multi-view display environment for various purposes, such as privacy, education, games.

While the above has been shown and described with respect to preferred embodiments of the invention, the invention is not limited to the specific embodiments described above, it is usually in the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.
