With the development of digital technology, various types of electronic products are being developed and distributed. In particular, various display devices such as TVs, mobile phones, PCs, notebook PCs, and PDAs are used in most households.

As the use of display devices has increased, the user needs for more diverse functions have also increased. Accordingly, the efforts of each electronic product manufacturer to meet the user needs has also increased, and products with new functions that have not existed in the past have appeared one after another.

In particular, in recent years, there is a high need for a technology that allows a plurality of users to view content desired by one common display device.

The display apparatus 100 combines and displays a plurality of different contents, and each of the plurality of glasses apparatuses 200-1 and 200-2 transmits only one content image displayed by the display apparatus 100. Displaying a combination of content means mixing and composing content to form and display an image frame or displaying content alternately. The alternating display of a plurality of contents may be performed by alternately displaying a frame containing image information of one content and then displaying a frame containing image information of another content. This means displaying a frame containing information.

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.

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.

In this case, time information for turning on or off the first shutter glass unit 250 and the second shutter glass unit 260 of the spectacles 200 to be synchronized with the display timing of one of the plurality of contents is included. do.

Meanwhile, the communication interface 210 may receive information about an image frame rate and an image frame period for each content from the display apparatus 100.

The controller 220 controls the operation of the first half of the spectacles 200. In particular, the controller 220 transfers the synchronization signal received from the communication interface unit 210 to the shutter glass driver 230 to control the operation of the shutter glass driver 230. That is, the controller 220 controls the shutter glass driver 230 to generate driving signals for driving the first shutter glass unit 250 and the second shutter glass unit 260 based on the synchronization signal.

The shutter glass driver 230 generates a driving signal based on the synchronization signal received from the controller 220. In particular, the shutter glass driver 230 may include the first shutter glass unit 250 and the second shutter glass unit based on a display timing of one of a plurality of contents displayed on the display apparatus 100 based on the synchronization signal. 260 may be opened.

The first shutter glass unit 250 and the second shutter glass unit 260 turn on or off the shutter glass according to a driving signal received from the shutter glass driver 230. Specifically, the first shutter glass unit 250 and the second shutter glass unit 260 simultaneously open the shutter glass when one of the plurality of contents is displayed, and turn off all of the shutter glasses when the other contents are displayed. Let's do it. Accordingly, a user wearing the spectacles 200 may view one content.

In the case of 3D content, the first shutter glass unit 250 and the second shutter glass unit 260 may alternately open and close the respective glasses. That is, the first shutter glass unit 250 may be opened at the timing when the left eye image constituting one 3D content is displayed according to the driving signal, and the second shutter glass unit 260 may be opened at the timing when the right eye image is displayed. Can be.

Not paired  Other content View  Embodiments that can be synchronized

Hereinafter, according to various embodiments of the present disclosure, an eyeglass device, a display device, and a content providing method using the same may be synchronized with another content view that is not currently paired.

Subsequently, a description will be given with reference to FIG. 5.

The controller 160 controls the operation of the first half of the display apparatus 100 as described above. In particular, the controller 160 may control one of the plurality of communication modules to transmit a synchronization signal by performing a connection operation with the glasses device according to a user command received from the glasses device. Here, the user command may be a pairing request message.

In detail, the controller 160 may control each Bluetooth communication module to transmit a synchronization signal by performing pairing with the Bluetooth communication module included in the glasses device according to a user command.

That is, the controller 160 broadcasts an Inquiry Message through the Bluetooth communication module, and searches for the glasses device within a range capable of Bluetooth communication. When the pairing request message is received in response to the query message from the eyeglass device, the controller 160 may transmit and receive a Bluetooth device address and a pin code with the eyeglass device to perform pairing. Here, the controller 160 may automatically perform pairing by registering the eyeglasses by automatically inputting the user without inputting the pin code directly. However, the present invention is not limited thereto, and the user may perform the pairing process by directly inputting pin codes of the display device and the eyeglass device.

In this case, the controller 160 may control each of the plurality of Bluetooth communication modules provided in the interface unit 150 to perform the pairing operation with the different glasses devices. Here, since each Bluetooth communication module transmits a synchronization signal to the paired eyeglasses, the display apparatus 100 may synchronize different eyeglasses to each of the plurality of contents. However, this is merely an example, and the controller 160 may control each of the plurality of Bluetooth communication modules to perform a pairing operation with at least one same eyeglass device.

Meanwhile, when a user command is received while one of the plurality of communication modules is connected to the glasses device, the controller 160 controls another one of the plurality of communication modules to perform a connection operation with the glasses device to transmit different synchronization signals. can do. That is, the controller 160 may control one communication module to communicate with different eyeglasses.

Specifically, when the controller 160 receives a pairing request message from the paired glasses device with one of the plurality of Bluetooth communication modules, the controller 160 exchanges the paired glasses device with the Bluetooth address and pin code through another Bluetooth communication module. By transmitting and receiving, another Bluetooth communication module may control to perform pairing with the glasses device. At this time, the controller 160 may release the connection with the Bluetooth communication module that has been paired with the spectacles. The glasses device may receive a synchronization signal different from a previously connected Bluetooth communication module from a newly connected Bluetooth communication module. Accordingly, a user wearing the spectacles can watch other contents.

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.

8 is a block diagram illustrating a configuration of an eyeglass device according to an embodiment of the present invention. According to FIG. 8, the spectacles 200 includes a communication interface 210, an inputter 240, and a controller 220. The spectacles 200 may interlock with a display device that alternately displays a plurality of contents.

The communication interface 210 communicates with the display device. In detail, the communication interface unit 210 communicates with the display apparatus according to various wireless methods, and receives a synchronization signal from the display apparatus.

For example, the communication interface unit 210 may include a Bluetooth communication module to communicate with a Bluetooth communication module in a display device and receive a synchronization signal having a transmission packet form according to the Bluetooth communication standard. Here, the transport packet according to the Bluetooth communication standard may include time information for synchronizing with the display timing of the content. Since the information contained in the transport packet has been described above, the redundant description is omitted.

The input unit 240 receives a user command for performing a connection operation with a plurality of communication modules included in the display device. To this end, the input unit 240 may include a switching button implemented as a touch sensor or an operation button.

The controller 220 controls the overall operation of the spectacles 200. In particular, when a user command is input, the controller 220 performs a connection operation with one of the plurality of communication modules included in the display device to receive a synchronization signal corresponding to one of the plurality of contents. 210 can be controlled.

In detail, when a user command is input, the controller 220 may selectively perform pairing with one of a plurality of Bluetooth communication modules included in the display device in order to receive a synchronization signal corresponding to one of a plurality of contents. The Bluetooth communication module provided in the unit 210 may be controlled.

For example, the controller 220 transmits a pairing request message through a Bluetooth communication module provided in the communication interface 210, and transmits and receives a Bluetooth address and a pin code with one of a plurality of Bluetooth communication modules provided in the display device. Pairing can be performed. When the pairing is completed, the controller 220 may receive a transport packet according to a Bluetooth communication standard including time information for synchronizing with the display timing of the content through the communication interface 210.

In this case, the controller 220 may selectively perform pairing with one of a plurality of Bluetooth communication modules included in the display device according to the number of times the user touches the switching button provided in the input unit 240. For example, the controller 220 performs pairing with the Bluetooth communication module 1 of the display device when the user touches the switching button once, and the Bluetooth communication module provided in the display device when the switching button is touched twice. The communication interface 210 may be controlled to perform pairing with the two.

The input unit 240 may include a plurality of switching buttons for receiving a user command for connecting to each of a plurality of communication modules provided in the display device. In this case, the controller 220 may perform a pairing with each of the plurality of Bluetooth communication modules included in the display device whenever a plurality of switching buttons are touched to receive synchronization signals corresponding to different contents. The Bluetooth communication module included in the 210 may be controlled.

For example, when the user touches the switching button 1, the controller 220 performs pairing with the Bluetooth communication module 1 included in the display device, and when the user touches the switching button 2, the controller 220 is connected to the Bluetooth communication module 2 provided in the display device. The communication interface 210 may be controlled to perform pairing.

Meanwhile, when a user command is input while being connected to one of the plurality of communication modules, the controller 220 performs a connection operation with another one of the plurality of communication modules to receive a synchronization signal corresponding to another one of the plurality of contents. The interface unit 210 may be controlled.

In detail, the controller 220 transmits a pairing request message to the display apparatus when a user command is input while pairing with a plurality of Bluetooth communication modules included in the display apparatus is completed. Accordingly, the controller 220 transmits / receives a Bluetooth address, a pin code, etc. from the display device through another Bluetooth communication module among the plurality of Bluetooth communication modules, so that the Bluetooth communication module provided in the communication interface 210 is connected to the other Bluetooth of the display device. It is possible to control the pairing with the communication module. Accordingly, the synchronization signal corresponding to the other of the plurality of contents can be received from the other Bluetooth communication module of the display device, so that the user wearing the spectacle device can watch the other contents.

9 is a flowchart illustrating a detailed configuration of an eyeglass device according to an embodiment of the present invention. According to FIG. 9, the spectacle device 200 may include a communication interface 210, an input unit 240, a controller 220, a shutter glass driver 230, a first shutter glass unit 250, and a second shutter glass unit ( 260). Before describing FIG. 9, a configuration having the same reference numerals as in FIG. 8 performs the same function, and thus redundant description will be omitted. In addition, the description of the configuration of the above-described spectacle apparatus 200 except for the contents described below among the respective components. However, parts necessary for the understanding of the present embodiment will be redundantly described.

As described above, the controller 220 transfers the synchronization signal received from the communication interface unit 210 to the shutter glass driver 230 to control the operation of the shutter glass driver 230.

The shutter glass driver 230 generates a driving signal based on the synchronization signal received from the controller 220 as described above. In detail, the shutter glass driver 230 may include the first shutter glass unit 250 and the second shutter glass unit 260 according to the display timing of one of the plurality of contents based on the synchronization signal received from the display apparatus. Open

Meanwhile, when the communication interface 210 is disconnected from one of the plurality of communication modules included in the display apparatus and connected to another communication module, the controller 220 may be configured to receive a synchronization signal received from another communication module connected to communicate with each other. The shutter glass driver 230 is controlled to generate a driving signal based on the driving signal. Accordingly, the shutter glass driver 230 based on the newly received synchronization signal, the first shutter glass unit 250 and the second shutter glass in accordance with the display timing of the other of the plurality of contents displayed on the display device. The unit 260 may be opened.

The first shutter glass unit 250 and the second shutter glass unit 260 open or off the shutter glass according to a driving signal received from the shutter glass driver 230. Specifically, the first shutter glass unit 250 and the second shutter glass unit 260 simultaneously open the shutter glass when one of the plurality of contents is displayed, and turn off all of the shutter glasses when the other contents are displayed. Let's do it. Accordingly, a user wearing the spectacles 200 may view one content.

Meanwhile, in the above-described exemplary embodiment, the display apparatuses generate synchronization signals corresponding to the display timing of the contents, and transmit the generated synchronization signals to the spectacles 200, but this is merely an example. That is, the display device may generate a transmission signal corresponding to the display timing of each content as one transport packet according to the Bluetooth communication standard and transmit the same to the eyeglasses 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. When the user command is input, the controller 220 may control to open / off the shutter glass according to the display timing of the content that does not match the glasses device information, thereby providing the user with other contents.

10 is a flowchart illustrating a content providing method of a display apparatus according to an exemplary embodiment.

First, a plurality of different contents are displayed (S1010). Specifically, a plurality of different contents are alternately arranged and displayed.

Thereafter, a synchronization signal is generated (S1020). Specifically, a synchronization signal for synchronizing the spectacles device corresponding to each content is generated according to the display timing of each content.

In operation S1030, the glasses and the glasses are connected. In detail, the connection operation is performed with one of the glasses devices of the plurality of communication modules according to a user command received from the glasses device. In this case, each of the plurality of communication modules is a Bluetooth communication module, and each Bluetooth communication module may be paired with a Bluetooth communication module provided in the glasses device according to a user command.

Then, the synchronization signal is transmitted (S1040). In detail, the synchronization signal may be transmitted using the communication module in which the connection operation is completed.

Meanwhile, in operation S1030, when a user command is received while one of the plurality of communication modules is connected with the glasses device, the other one of the plurality of communication modules may perform a connection operation with the glasses device to transmit different synchronization signals. .

11 is a flowchart illustrating a content providing method of an eyeglass device according to an exemplary embodiment. In particular, FIG. 11 illustrates a content providing method of a spectacle device interlocked with a display device that alternately displays a plurality of contents.

First, a user command is input (S1110). In detail, a user command for performing a connection operation with a plurality of communication modules included in the display apparatus is received.

Thereafter, if a user command is input (S1110-Y), the connection operation is performed (S1120). That is, a connection operation with one communication module of the plurality of communication modules is performed.

In operation S1130, a synchronization signal is received. In detail, when the connection operation is performed, a synchronization signal corresponding to one of the plurality of contents may be received.

Meanwhile, each of the plurality of communication modules included in the display device is a Bluetooth communication module, and the glasses device may communicate with the plurality of communication modules included in the display device using the Bluetooth communication module. In this case, step S1120 may control the Bluetooth communication module to perform pairing with one of the plurality of Bluetooth communication modules, in order to receive a synchronization signal corresponding to one of the plurality of contents when a user command is input. have.

In addition, the glasses apparatus may include a plurality of switching buttons for receiving a user command for connecting to each of the plurality of communication modules. In this case, in operation S1120, whenever the plurality of switching buttons are touched, the Bluetooth communication module may be controlled to perform a pairing operation with each of the plurality of Bluetooth communication modules included in the display device.

Meanwhile, in operation S1120, when a user command is input while being connected with one of the plurality of communication modules, the operation may be performed with another one of the plurality of communication modules to receive a synchronization signal corresponding to another one of the plurality of contents. have.

Meanwhile, the content providing method according to the present embodiment may open the first and second shutter glasses in accordance with the display timing of one of the plurality of contents based on the synchronization signal received from the display apparatus.

Since each embodiment of FIG. 10 and FIG. 11 has been described above, overlapping description thereof will be omitted.

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.

According to the operating condition of the spectacles mode  Example of performing a switchover

Hereinafter, a display apparatus and a mode switching method of the display apparatus for performing mode switching according to an operation state of each of the plurality of eyeglasses according to various embodiments of the present disclosure will be described.

12 is a conceptual diagram illustrating an output of the display apparatus 100 when one content view of the display apparatus 100 is turned off.

However, in a situation in which a plurality of content views are output, a case in which the spectacle device 200 connected to any one content view is turned off. For example, as shown in FIG. 12, one of two glasses apparatuses 200 matched to two different content views may be turned off. In this case, if there is no other glasses device 200 matched with the content view 2, since only the content view 1 matches the glasses device 200-2, the display device 100 also does not need to output a plurality of content views. . In particular, in the case of outputting a plurality of content views alternately, the number of image frames of each content view is reduced by half compared to the case of outputting only one content view, and thus the display resolution is inferior. Therefore, a clear image cannot be viewed. . In addition, since image data for different content views must be received and image processed, power loss is inevitably high. Therefore, when the number of content views actually matched with the eyeglasses 200 is reduced by turning off one or more eyeglasses 200 in a situation where a plurality of content views are output, the number of content views is reduced or a single view is reduced. You need to do a mode switch to switch to mode. However, when different content views are output, the user viewing one content view is difficult to know about the viewing situation of another user, and thus the display apparatus 100 recognizes that the number of content views is reduced and is output. It should be possible to perform mode switching operation to reduce the number of content views or switch to single view mode.

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.

As shown in FIG. 5, the display apparatus 100 according to various embodiments of the present disclosure may include a plurality of receivers 110-1, 110-2,..., 110-n, and a plurality of signal processor 120-1. 120-2,..., 120-n), a display unit 130, a synchronization signal generator 140, an interface unit 150, and a controller 160.

In addition to the contents described below, the components are in accordance with the above-described embodiments, and in the following, the overlapping contents will be omitted as much as possible, but the overlapping contents will be described as necessary to help the understanding of the present embodiment.

The synchronization signal generation unit 140 generates a synchronization signal for synchronizing the glasses apparatus 200 corresponding to each content according to the display timing of each content. In particular, when there is a change in the number of content views due to a mode change of the display apparatus 100 as described below, a synchronization signal is generated according to the number of newly changed content views.

The interface unit 150 communicates with the spectacles 200. In this case, the communication interface unit 150 may communicate with the spectacle apparatus 200 according to various wireless methods to transmit a synchronization signal to the spectacle apparatus 200 or may be paired with the spectacle apparatus 200.

For example, the communication interface unit 150 may be provided with a Bluetooth communication module to communicate with the glasses device 200, and generate a synchronization signal as a transport stream according to the Bluetooth communication standard to transmit the glasses to the glasses device 200. .

If there is a change in the number of content views and there is a mode change of the display apparatus 100, the on / off offset time of the shutter glass of the spectacle apparatus 200 is newly set and transmitted according to the synchronization signal matched to the changed content view. The stream will contain this information.

The control unit 160 will be described below. As described above, the controller 160 controls the overall operation of the display apparatus 100. In particular, the controller 160 may perform mode switching according to an operation state of each of the plurality of eyeglasses 200. For example, one or more eyeglasses 200 of the plurality of eyeglasses 200 may be turned off to leave only one content view matched with the eyeglasses 200. In this case, since viewing is performed only through one content view, it is not different from the single view mode, but the display apparatus 100 still outputs a plurality of content views alternately. Therefore, as described above, the power loss is large, and since the display resolution is lower than that of the single view mode, a clear screen cannot be viewed. In this case, the controller 160 recognizes that the one or more eyeglasses 200 are turned off, and accordingly switches the display apparatus 100 to the single view mode. As another example, one or more eyeglasses 200 of the plurality of eyeglasses 200 may be turned off to reduce the number of content views matched with the eyeglasses 200. In this case, since the number of content views output through the display apparatus 100 is larger than the number of content views actually viewed, power loss and low resolution problems occur as described above. Therefore, when the one or more eyeglasses 200 are turned off and the number of content views is reduced, the controller switches the display apparatus 100 to the multi-view mode corresponding to the number of remaining content views. As another example, when the one or more eyeglasses 200 change the matched content view, the total number of content views matched with the eyeglasses 200 may change. For example, a glasses device 200 is matched with a content view that broadcasts a sports program, and the user changes the content view to a content view that broadcasts a drama, and the other glasses device 200 matched with a content view that broadcasts a sports program. If is not present, the number of content views matched with the spectacles 200 is reduced. In this case, the controller 160 switches the display apparatus 100 to the multi-view mode corresponding to the number of remaining content views. Similarly, when the number of content views matched with the spectacles 200 is reduced and only one is left, the controller 160 switches the display apparatus 100 to the single view mode. FIG. 15 illustrates a situation in which the display apparatus 100 is thus switched to the single view mode when one glasses apparatus 200-1 is turned off when the number of content views is two.

In order to change the mode, the display apparatus 100 should receive information about an operation state of the spectacle apparatus 200 from the spectacle apparatus 200. When a turn-off command is input through the input unit 240 of the spectacle apparatus 200, the spectacle apparatus 200 displays that the power of the spectacle apparatus 200 is turned off through the communication interface 210. The device 100 may be informed. Then, the interface unit 150 of the display apparatus 100 receives the turn-off input from the spectacle apparatus 200 and terminates the matching of the contents view with the spectacle apparatus 200. Similarly, the case where the content view matched with the spectacles 200 is changed. That is, a command for changing the content view may be input through the input unit 240 of the spectacle apparatus 200 which will be described later, and the spectacle apparatus 200 may view the content view of the spectacle apparatus 200 through the communication interface 210. Informs the display apparatus 100 that is changed. The interface unit 150 of the display apparatus 100 receives a change command input of a content view from the glasses apparatus 200.

Hereinafter, a mode switching method will be described.

13 and 14 are flowcharts illustrating a mode switching method of a display apparatus according to various embodiments of the present disclosure.

First, a plurality of contents are received (S1305 and S1405), and a plurality of contents are respectively processed to form an image frame (S1310 and S1410). Thereafter, the plurality of content views are output by combining the image frames of the respective contents (S1315 and S1415), and a synchronization signal for synchronizing the plurality of content views and the plurality of eyeglasses is generated (S1320 and S1420). Then, the synchronization signal is transmitted to the plurality of spectacles (S1325, S1425). When the operation state of the spectacle device is changed in a situation in which a plurality of content views are output (S1330-Y, S1430-Y), when the display is switched from the multi view mode to the single view mode (S1435-Y), the display apparatus 100 Switch to single view mode (S1440). Accordingly, the content is received and signal-processed according to the single view mode (S1450, S1455, S1460, and S1465). If the multi-view mode is switched to another multi-view mode in which the number of content views is reduced (S1435-N), the multi-view mode corresponding to the number of remaining content views is switched (S1445).

Meanwhile, when the spectacle apparatus is turned on again while being switched to the single view mode, the step of switching to the multi view mode may be further included.

Hereinafter, the eyeglass device 200 according to various embodiments of the present disclosure will be described.

16 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. 16 is interlocked with the display apparatus 100 that alternately outputs a plurality of contents in an image frame unit, 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.

The input unit 240 is configured to receive a turn-on command, a turn-off command, or a content view change command of the spectacle apparatus 200. The input unit 240 of the eyeglass apparatus 200 that matches one of the plurality of content views receives a turn-on command, a turn-off command, or a content view change command, and the communication interface 210 receives a display device ( 100). In the case of the turn-on command, the spectacle apparatus 200 may be turned on, and the mode of the display apparatus 100 may change according to the selection of the content view. When the turn-off command is input, the spectacles 200 is powered off, and the display apparatus 100 detects whether there is a change in the number of content views matched with the spectacles and changes the mode when there is a change. When a content view change command is input, the content view of the eyeglasses 200 is changed, and the display apparatus 100 detects whether there is a change in the number of content views matched with the eyeglasses, and switches modes when there is a change. . However, the turn-on command, the turn-off command, or the content view change command may not be input only through the input unit 240, but may be input through a separate device such as a remote controller.

The communication interface 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, the turn-on command, the turn-off command, or the input signal through the input unit 240. The content view change command 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.

The controller 220 controls the operation of the first half of the spectacles 200. In particular, the controller 220 transfers the synchronization signal received from the communication interface unit 210 to the shutter glass driver 230 to control the operation of the shutter glass driver 230. That is, the controller 220 controls the shutter glass driver 230 to generate driving signals for driving the first shutter glass unit 250 and the second shutter glass unit 260 based on the synchronization signal. In addition, the communication interface 210 may be controlled to transmit a turn-on command, a turn-off command, or a content view change command input through the input unit 24 to the display apparatus 100. In particular, when there is a mode change of the display apparatus 100, the spectacle apparatus 200 of the spectacle apparatus 200 according to the on / off offset time of the changed shutter glass of the spectacle apparatus 200 included in the transport stream received from the display apparatus 100. Control the shutter glass to be on or off.

The shutter glass driver 230 generates a driving signal based on the synchronization signal received from the controller 220. In particular, the shutter glass driver 230 may include the first shutter glass unit 250 and the second shutter glass unit based on a display timing of one of a plurality of contents displayed on the display apparatus 100 based on the synchronization signal. 260 may be opened.

The first shutter glass unit 250 and the second shutter glass unit 260 turn on or off the shutter glass according to a driving signal received from the shutter glass driver 230. Specifically, the first shutter glass unit 250 and the second shutter glass unit 260 simultaneously open the shutter glass when one of the plurality of contents is displayed, and turn off all of the shutter glasses when the other contents are displayed. Let's do it. Accordingly, a user wearing the spectacles 200 may view one content.

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.

When the synchronization signal is received, the spectacle apparatus 200 may check the display timing corresponding to the information of the spectacle apparatus 200 and turn on or off the shutter glass according to the confirmed display timing. That is, the spectacles 200 may control the shutter glass driver 230 to sequentially generate driving signals based on synchronization signals corresponding to each content included in the transport stream. Accordingly, the first shutter glass unit 250 and the second shutter glass unit 260 are opened whenever an image frame of each content is displayed.

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.

Hereinafter, a polarization method will be described with reference to FIG. 17 as another embodiment of the present invention. FIG. 17 is a conceptual diagram illustrating a situation in which an image is viewed by the spectacle apparatus 200 having a polarizing lens for each image when the image frames of the contents polarized in the horizontal direction and the vertical direction are alternately displayed.

The display apparatus 100 described above may further include a polarization member 180. The polarizing member 180 may include a liquid crystal layer (not shown) to polarize an 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. 17 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 alternately displayed. It is shown.

According to various embodiments of the present disclosure, the mode switching of the display apparatus 100 is performed according to the operation state of each of the plurality of eyeglasses 200, so that a user can watch a high resolution clear image without manual mode manipulation and consume power. There is less effective to do.
