In addition, the remote control device 300 detects the closest eyeglasses among the plurality of eyeglasses 200-1 and 200-2 and transmits a control command for controlling the content view synchronized to the eyeglasses.

Here, the content view means a set of image frames for one content that can be viewed by a viewer wearing a spectacles when the image frames of each content are alternately arranged and displayed. However, the content view is a different concept from each content. For example, if a viewer wears a glasses device synchronized with a specific content view and changes the TV channel while watching the content A, or plays another DVD content or the like to watch the content C, the content is changed from A to C. It changes, but the content view does not change. That is, the concept of a kind of channel that can watch the content as the concept of the content.

As illustrated in FIG. 1, the display apparatus 100 alternately displays contents 1 and 2 through a plurality of content views. The spectacle device 1 200-1 receives a synchronization signal corresponding to the content view 1, and opens the shutter glass at the time when the content 1 is displayed, and a viewer wearing the spectacle device 1 200-1 may view the content 1.

The display device 100 may be implemented as various devices including a display unit such as a TV, a mobile phone, a PDA, a notebook PC, a monitor, a tablet PC, an e-book, an electronic picture frame, a kiosk, and the like.

The plurality of receivers 110-1, 110-2,..., 110-n respectively receive a plurality of different contents. 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. As such, the plurality of receivers 110-1, 110-2,..., 110-n may be implemented in various forms according to embodiments.

Also, the plurality of receivers 110-1, 110-2,..., 110-n do not necessarily receive content from a source of the same type, and the plurality of receivers 110-1, 110-2,. 110-n) may receive content from different types of sources. For example, the receiver 1 110-1 may be implemented in a form including a tuner, a demodulator, an equalizer, and the like. The receiver 2 110-2 may be implemented as a network interface card.

Meanwhile, in FIG. 2, the display apparatus 100 is described as including a plurality of receivers. However, according to an exemplary embodiment, the plurality of receivers may be implemented as one receiver. That is, one receiver may receive a plurality of contents.

The signal processing units 120-1, 120-2,..., 120-n process the contents received from the plurality of receivers 110-1, 110-2,..., 110-n, respectively. An image frame can be configured. The signal processor 120 will be described in more detail with reference to FIG. 2.

3 is a block diagram illustrating a specific configuration of a signal processor according to an exemplary embodiment.

As shown in FIG. 3, the signal processor 1 120-1 includes a video processor 1 121-1 and a frame rate converter 1 122-1. Although only one signal processor 1 120-1 is illustrated in FIG. 3, all of the other signal processors 120-2,..., 120-n may have the same structure as that of FIG. 3.

The video processor 1 121-1 performs signal processing on video data included in content received from the receiver 1 110-1. In detail, the video processor 1 121-1 includes a decoder (not shown) that decodes video data, and a scaler (not shown) that performs up or down scaling in accordance with the screen size of the display 130. can do.

In addition, the video processor 1 121-1 may convert the video data into a data format corresponding to the frame rate converter 1 122-1. Specifically, while the input video data is in a top-to-bottom format, the frame rate converter 1122-1 performs a frame in a side-by-side format. In the case of processing, the video processor 1 121-1 may convert an image frame of each content to be in a side-by-side format by connecting side by side in a horizontal direction.

The frame rate converter 1 122-1 converts the frame rate of the content provided from the video processor 1 121-1 to match the output rate of the display apparatus 100. For example, if the display apparatus 100 operates at 60 Hz in the single view mode, the frame rate converter 1 122-1 converts the frame rate of each content to 60 Hz, the same as the frame rate in the single view mode. I can convert it. In the multi-view mode, the display apparatus 100 operates at an output rate of n * 60Hz when there are n contents.

In FIG. 2, the display apparatus 100 is described as including a plurality of signal processing units. However, according to an exemplary embodiment, the plurality of signal processing units may be implemented as one signal processing unit. That is, one signal processor may signal-process a plurality of contents.

The display unit 130 alternately arranges and displays the image frames of the contents configured in the plurality of signal processing units 120-1, 120-2,..., 120-n. Specifically, the display unit 130 multiplexes and displays at least one image frame of each content provided by the plurality of signal processing units 120-1, 120-2,. do. In some cases, the display 130 may up or down scale an image frame for each content according to the screen size.

For example, in the case of a shutter glass type display device, the display unit 130 alternately arranges at least one image frame of the first content, the image frame of the second content, ..., and the image frame of the n-th content. Configure to display. The user wears the spectacles 200 linked to the timing at which the contents are displayed on the display 130, and watches the contents desired by the user. Specifically, the spectacle device 200 is provided with a left eye shutter glass and a right eye shutter glass. The left eye shutter glass and the right eye shutter glass are alternately turned on / off when watching 3D content, but as described above, when viewing a frame in which at least one image frame is alternately arranged, output of the content synchronized with the spectacle apparatus. It is turned on and off collectively according to the timing. Accordingly, the user can watch the content separately from other users.

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 plurality of images representing the same object 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.

The controller 140 controls operations of the first half of the display apparatus 100. Specifically, the controller 140 includes a plurality of receivers 110-1, 110-2,..., 110-n, and a plurality of signal processors 120-1, 120-2,. And control each of the display units 130 to perform a corresponding operation.

In addition, when a predefined event occurs, the control unit 140 performs a plurality of signal processing units 120-1, 120-2,..., 120-n and the display unit 130 to perform an operation corresponding to the event. ) Can be controlled.

Here, the predefined event is an event in which a control command for controlling one of the plurality of content views is received from the remote control device, and at least one of the plurality of contents is not synchronized with the spectacles 200. The event may be an event, an event in which a multi-view mode start command is input, an event in which a control authority request command is input from the remote control apparatus 300, an event in which a multi-view mode end command is input, or the like.

Specific operations of the controller 140 according to the predefined event will be described later by dividing according to embodiments.

4 is a block diagram showing the configuration of a display device according to another embodiment of the present invention.

Referring to FIG. 4, 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), as well as the display unit 130 and the controller 140, may further include a synchronization signal generator 150 and the interface unit 160. Here, the controller 140 may control each of the synchronization signal generator 150 and the interface unit 160 to perform a corresponding operation.

The synchronization signal generator 150 generates a synchronization signal for synchronizing the glasses apparatus corresponding to each content according to the display timing of each content. That is, the synchronization signal generator 150 generates a synchronization signal for opening the shutter glass of the spectacle device at the time when the image frame of each content is displayed in the multi view mode.

The interface unit 160 is connected to at least one glasses device to perform communication. In this case, the interface unit 160 may communicate with the spectacle apparatus according to various wireless methods, transmit a synchronization signal to the spectacle apparatus, and receive a selection command from the spectacle apparatus.

For example, the interface unit 160 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.

The transport stream transmitted from the interface unit 160 to the spectacles 200 includes offset time information for turning on / off the shutter glasses of the spectacles in synchronization with the reference timing and the display timing of the contents. Specifically, the time information includes an offset time for turning on the left eye shutter glass of the spectacle device, a left shutter close offset for turning off the left eye shutter glass, and an offset time for turning on the right eye shutter glass. open offset), and information on the right shutter close offset of turning off the right eye shutter glass.

The offset time is delay information from the reference time point to the on or off time point of the shutter glass and may vary depending on the frame rate of the display device or the number of content views. That is, the spectacle apparatus turns on / off the left eye shutter glass and the right eye shutter glass when the offset time has elapsed from the reference time point.

The reference time point may be a time point at which a vertical synchronization signal (ie, frame sync) is generated in the image frame (information about the reference time point may be included in the transport stream). In addition, the transport stream may include information about a clock signal used in the display apparatus 100. Therefore, upon receiving the transport stream, the spectacle device synchronizes its clock signal with the clock signal of the display apparatus 100, and determines whether the offset time has elapsed from the time when the vertical synchronization signal is generated using the clock signal. The glass can be turned on / off.

In addition, the transport stream may further include information on the period of the frame sink, information for indicating the decimal point information when the period of the frame sink has a decimal point.

Hereinafter, a method of synchronizing the display apparatus 100 and the spectacles 200 will be described in detail with respect to embodiments.

In an embodiment, the synchronization signal generator 150 may generate different synchronization signals for each of the plurality of content views. In this case, the synchronization signal generator 150 may generate a synchronization signal having different reference views for each content view, or may have the same reference view. It is possible to generate synchronization signals with different offset times.

When the spectacle apparatus 200 and the display apparatus 100 are connected, the spectacle apparatus 200 receives one synchronization signal among a plurality of synchronization signals from the display apparatus 100 and is synchronized with the corresponding content view. On the other hand, when the user inputs a command to change the content view to the glasses device 200, the glasses device 200 transmits a content view selection command to the display device 100. When the display apparatus 100 receives the content view selection command, the display apparatus 100 may transmit a synchronization signal corresponding to the changed content view to the eyeglass apparatus 200 so that the content view synchronized with the eyeglass apparatus 200 may be changed.

In another embodiment, the synchronization signal generator 150 may generate only one synchronization signal as a reference. Here, one synchronization signal as a reference may be a synchronization signal corresponding to the main content view among the plurality of content views. When the glasses apparatus 200 and the display apparatus 100 are connected, the glasses apparatus 200 receives a synchronization signal as a reference from the display apparatus 100 and is synchronized with a corresponding content view. Here, when the user inputs a command to change the content view to the spectacle apparatus 200, the spectacle apparatus 200 may be synchronized to another content view by simply changing the sync signal as a reference.

The interface unit 160 transmits / receives a Bluetooth device address, a pin code, and the like with the glasses device, and performs pairing according to a Bluetooth communication method.

In one embodiment, the interface unit 160 may have a plurality of Bluetooth addresses, and one eyeglass device may be connected to one Bluetooth address. At this time, according to the order in which the spectacles 200 are connected to the interface unit 160, the Bluetooth address may be given to each spectacles in an ascending or descending order. The interface unit 160 may be set to be excluded from the Bluetooth address search target in order to prevent the other glasses device from being connected to the Bluetooth address used for the connection with the eyeglass device 200.

When pairing is completed, the interface unit 160 may register information about the glasses device, for example, identification information unique to the glasses device or a Bluetooth address used for pairing. The interface unit 160 matches information about each eyeglass device to a transport stream corresponding to the display timing of each content, and transmits the transport stream to each eyewear device based on the information obtained through pairing.

When the glasses device receives the transport stream, the glasses device may determine whether the glasses device corresponds to the glasses device information, and may turn the glasses on or off based on the time information included in the checked transport stream.

Although the above-described embodiment has been described as the interface unit 160 and the glasses device to perform 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. .

Although the interface unit 160 has been described as performing communication with a plurality of eyeglasses as one communication module, the interface unit 160 may be implemented as a plurality of communication modules which individually communicate with each eyeglass device. Alternatively, when the display apparatus 100 supports a plurality of wireless communication schemes, the interface unit 160 may be implemented to include a plurality of communication modules according to each wireless communication scheme. For example, the interface unit 160 may include a plurality of communication modules according to various wireless communication schemes such as Bluetooth, Zigbee, and Wifi.

Although not shown in FIG. 2, the display apparatus 100 further includes a configuration in which audio data included in each content is differently provided 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 each decoded audio data into a different frequency signal, an audio output unit (not shown) for transmitting each modulated audio data to the spectacles, etc. may be further included. . Each audio data output from the audio output unit (not shown) is provided to the user through output means such as earphones provided in the spectacle device. 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 (not shown) 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.

For example, the interface unit 210 may be implemented as a Bluetooth communication module to communicate with the display apparatus 100 to receive a synchronization signal and to transmit information about the spectacles 200. In addition, the user command (or control command) input through the input unit 240 may be transmitted to the display device.

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 with reference to FIG. 4, duplicate description thereof will be omitted.

The controller 220 controls the operation of the first half of the spectacles 200. In particular, the controller 220 transmits the synchronization signal received from the 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.

To this end, the input unit 240 may include a button, a touch pad, a toggle button, etc. for selecting a content view. When the user inputs a selection command for selecting one of the plurality of content views to the input unit 240, the interface unit 210 transmits information about the selected content view to the display apparatus 100, and displays the display apparatus 100. A synchronization signal corresponding to the selected content view may be received from the. In addition, the input unit 240 may receive a response signal of the consent or the opposite to a user command or a control command for controlling any one of the plurality of content views.

Based on the above description, a process in which the display apparatus 100 performs an operation corresponding to the generated event when the predefined event occurs will be described in detail by embodiment.

<Plural contents  One of the views contents View  When an event occurs that receives a control command to control>

7 is a diagram for explaining a situation in which a control command received from a remote control device affects another content view.

 When a plurality of viewers wear the glasses 200-1 and 200-2 synchronized with different content views, respectively, and a user watches a content, a user inputs a user command to control the content view that he or she is watching. In this case, there may be an effect on a user who views content through another content view. In particular, since a plurality of users are in a situation where only their content is being viewed, there is a case where the display apparatus 100 is controlled without being aware of other users. For example, as shown in FIG. 6, a drama is broadcasted in content viewed through one eyeglass device 200-1, but a movie that is screened in content viewed through another eyeglass device 200-2 ends. In one case, a user wearing the other glasses device 200-2 may unknowingly turn off the power of the display device 200-2. In this case, the content view shown through the former eyeglass apparatus 200-1 also affects the user's input of the control command according to the type of the control command, and it is necessary to obtain consent of the control operation.

Here, when a control command for controlling one content view of the plurality of content views is received, the controller 140 may selectively display a message informing of the fact that the control command is input according to the type of the control command in the other content view. have. As described above, when a control command is input to the display apparatus 100 from the eyeglasses 200-1 and 200-2 watching one content view, other content views may be affected. On the other hand, the control command may not affect other content views, or may be ignored even if there is an influence. Therefore, when the control command is received from the remote control signal receiving unit 170, the control unit 140 controls to perform the control operation when it is not necessary to notify (notice) or otherwise change the content view according to the type of the control command. do.

Control commands are divided into executable actions and execution restriction actions. This is due to the presence or absence of influence on other content views. If no other content view is affected, it is defined as an executable action in any case. On the other hand, when there is an influence on other content views, execution can vary depending on the consent of other users or other situations, so it is defined as an execution restriction operation.

As described above, the executable operation refers to a control command when there is no influence on another content view. The control command for the executable operation may include a content change command for changing the content of the selected content view, a volume adjustment command for adjusting an audio signal volume of the content, and an OSD menu for displaying an OSD menu on the selected content view. For example, the display command, the image quality adjustment command for adjusting the image quality of the image frame displayed in the selected content view.

For example, when the volume control signal is input from one eyeglass device, the volume control signal may be executed because controlling the volume of the eyeglass device does not affect other content views. However, since the control command for adjusting the output volume (master volume) of the display apparatus 100 may affect other content views, this is an execution restriction operation. As another example, there is a content change operation. As described above, various types of content can be viewed through one content view. Therefore, changing content in one content view does not affect other content views.

The execution restriction operation refers to a control command when there is an influence on another content view as described above. For example, there is a power on / off control operation and an output characteristic adjustment operation of the display device. That is, as described above, a user watching one content view may unknowingly turn off the power of the display apparatus 100. In this case, since other content views are no longer available for viewing, this corresponds to an execution restriction operation. Another example is the operation of adjusting the output characteristics. This mainly refers to a control command that has a dependency of the display apparatus 100. For example, the screen brightness may be adjusted or the reception method may be changed.

8 is a block diagram illustrating a configuration of a display apparatus according to another exemplary embodiment.

According to FIG. 8, since the display apparatus 100 must distinguish between the executable operation and the execution limit operation, the display apparatus 100 may further include a storage unit 180 that stores control operation information divided into the executable operation and the execution limit operation.

When the control command is received from the remote control signal receiving unit 170, the controller 140 compares the received control command with control operation information stored in the storage unit 180 to determine whether the received control command is an executable operation or an execution restriction operation. It can be determined whether or not.

If the control command is a control command for the above-described executable operation, the controller 140 performs a control operation corresponding to the control command on the content view. That is, in the above-described embodiment, in the case of the control command for adjusting the volume of the content view, the volume control signal is transmitted without notifying other content views. On the other hand, if the control command is a control command for the execution restriction operation, the signal processing unit 120 and the display unit 130 are controlled to display a message indicating the input of the control command in the other content view. That is, the signal processor 120 converts a message regarding the control command into image data and mixes the image frame of the other content view, and the display unit 130 outputs the mixed image frame to the other content view. For example, when a power off control signal is input through one content view, a message “The user of channel 1 is about to power off” may be displayed in another content view.

In this case, a user who views another content view may transmit a response signal to the display apparatus 100 that agrees or opposes the control command. According to an embodiment, the spectacle apparatus 200 may receive a signal that agrees or opposes a control command from the user through the input unit 240 and transmits a consent signal to the display apparatus 100 through the interface unit 210. In addition, such a signal may be transmitted through the remote control apparatus 300, or may be directly inputted through an input unit (not shown) located in the display apparatus 100. In the example of receiving a signal through the input unit of the spectacle apparatus, the control unit 140 executes a control operation corresponding to the control command when a response signal agreeing to the control command is received from another spectacle apparatus matching the other content view, and the control is performed. When a response signal opposite to the command is received, the control operation corresponding to the control command is not executed. That is, in the example of turning off the display apparatus 100, the controller 140 displays a message, "A user of channel 1 tries to turn off the power. Do you agree?", And matches the other content view. When a response signal agreeing to turn off the power is received from the interface unit 210 of the other glasses device, the power of the display apparatus 100 is turned off.

Meanwhile, there may be a case in which no response signal is received by the display apparatus 100 for a predetermined time. In this case, priority may be given to the content view in which the control command is input to perform a control operation corresponding to the control command. That is, if a response signal for a control command is not received from another eyeglass device that matches another content view for a preset time from when the message is output, the controller 140 may execute a control operation corresponding to the control command. However, unlike this, in consideration of the influence on the other content view, it may be regarded that the opposite response signal is given by giving priority to the other content view. In this case, no control operation corresponding to the control command is performed. In addition, if no response signal is received due to the difference of control commands, if the influence on other content views is large, the opposite response signal is regarded as received, and if the influence is small, the agreed response signal is received. There may also be a method of performing the control operation corresponding to the control command in consideration of.

Accordingly, the method of executing the control operation may be changed according to the degree to which the control command input to one of the plurality of content views affects the other content views. In particular, when the influence on other content views is large, the other content views are notified, and execution consent is obtained, thereby enabling more stable multi-view display.

<Plural contents  At least one of the views contents View  With glasses device Not synchronized  If an event has occurred

If it is determined that there is content that is not mapped with the spectacles, the control unit 140 controls to add a message object for inducing connection with the spectacles to the content view that is not mapped with the spectacles 200. This will be described in detail with reference to FIG. 9.

9 is a diagram illustrating a displayed result of a message object for inducing connection with a spectacles device according to an embodiment of the present invention.

The plurality of glasses apparatuses 200-1 and 200-2 communicate with the display apparatus 100 using unique identification information, and the glasses apparatuses 200-1 and 200-2 are paired with the display apparatus 100. When pairing, identification information unique to the glasses apparatus 200-1 and 200-2 is transmitted to the display apparatus 100. In another embodiment, the Bluetooth address of the interface unit 160 used to connect to the eyeglasses 200-1 and 200-2 may be used as information for identifying the eyeglasses. The communication interface 160 of the display apparatus 100 may transmit any one of the synchronization signals corresponding to each of the plurality of content views according to the identification information or the Bluetooth address received from the eyeglasses 200-1 and 200-2. In operation 200-1 and 200-2, mapping information between the respective content view and the spectacle device may be generated or stored.

Here, the interface unit 160 of the display apparatus 100 checks the mapping information indicating which glasses apparatus each of the plurality of contents is mapped to under the control of the controller 140, and checks the glasses apparatus 200-among the plurality of contents. It may be determined whether there is content that is not mapped with 1, 200-2).

When there is content that is not synchronized with the glasses apparatus 200-1, 200-2, the glasses apparatus 200 of the signal processing units 120-1, 120-2,..., 120-n is present. The signal processing unit for processing content that is not synchronized with the display unit adds a message object for inducing connection with the spectacles 200 to the image frame of the corresponding content, and the display unit adds the image frame to which the message object is added to the image frame of the other content. Can be displayed alternately.

In addition, when a new eyeglass device is connected, the controller 140 may control the new eyeglass device to be automatically synchronized with a content view that is not synchronized with the eyeglass device, and corresponding content view according to a message object inducing connection of the eyeglass device. If is mapped to at least one eyeglass device, the message object displayed in the corresponding content view may be controlled to disappear.

According to FIG. 9, the display apparatus 100 displays content 2, and each of the eyeglasses 200-1 and 200-2 is synchronized with the content view 1 and the content view 3 to display the content 2 at the timing of displaying the content 2. The shutter glasses of (200-1, 200-2) are all closed. Since the glasses synchronized with the content view 2 do not exist, the display apparatus 100 may display a message object “Connect the glasses.” Which is a message object for inducing connection between the content view 2 and the glasses device.

On the other hand, viewers who wear glasses and watch contents 1 and 3 cannot see the message object displayed on content 2, while viewers who watch the display screen without wearing the glasses wear a display screen in which images of a plurality of contents overlap. The message object added to the content 2 may be viewed in a state overlapped with another content image. Accordingly, a viewer who views the display screen without wearing the eyeglasses may recognize that some of the currently displayed content views are displayed without being synchronized with the eyeglasses.

Here, when the new glasses device is connected to the display device 100, the new glasses device may be automatically mapped to the content view 2 which is not mapped to the existing glasses devices 200-1 and 200-2.

Meanwhile, the message object for inducing connection with the spectacles device may be any object not only illustrated in FIG. 9 but that the corresponding content is not mapped with the spectacles. For example, the message may indicate that the glasses are not mapped, such as "glasses are not connected", or a message providing a specific method of connecting the glasses.

Accordingly, it is possible to intuitively know that the spectacle device is not connected to a specific content without disturbing the viewer who is watching the content in the multi view mode, and the new spectacle device is more convenient for the content that is not connected to the spectacle device. Can be mapped with

<Multi view mode  When an event occurs where the start command is entered>

If the predefined event is an event in which a multi-view mode start command is input, the controller 140 inquires whether image frames of the plurality of content views are synchronized with the corresponding content view when the multi-view mode start command is input. The message object may be displayed, and each content may be controlled to be sequentially mapped to the spectacles. This will be described in detail with reference to FIG. 10.

FIG. 10 is a diagram illustrating a result of displaying a message object inquiring whether to synchronize with content according to an exemplary embodiment.

When a multi-view start command is input from the user, the display apparatus 100 starts the multi-view mode to alternately display a plurality of contents. Here, the plurality of signal processing units may add a message object for inquiring whether to map the corresponding content to the image frames of each of the plurality of contents, and the display unit may alternately display each image frame to which the object is added.

The interface unit 160 sequentially maps each content view to the spectacles 200-3, 200-4, and 200-5 connected to the display apparatus 100. Here, one content view may be mapped for a predetermined time and another content view may be mapped when the predetermined time elapses. Also, the plurality of glasses apparatuses 200-3, 200-4, 200-5 may be performed in the same manner when the glasses apparatus 200-3, 200-4, 200-5 are connected to the display apparatus 100.

Meanwhile, when a response to a message is received from at least one eyeglass device, the interface unit 160 may map the content view displayed at the time when the response is received and the eyeglass device which transmitted the response. The response to the message refers to a content selection command input through the input unit or the remote control device of the glasses apparatus 200-3, 200-4, 200-5.

Referring to FIG. 10, in operation (a), the display apparatus 100 alternately displays contents 1, 2, and 3, and is currently displaying an image frame of content view 1. A message object "Add button to watch this screen" is added to the video frame of each content. On the other hand, the plurality of eyeglasses 200-3, 200-4, and 200-5 are all mapped to the content view 1. In this case, when a selection command for selecting content 1 currently mapped is input through the input unit 240-3 of the glasses device 200-3 on the left side, the glasses device 200-3 on the left side displays the display device 100. The glasses may transmit a selection command to the glasses and the communication interface of the display apparatus 100 may continue to map the contents 1 to the glasses 1 on the left even if a predetermined time interval elapses.

FIG. 10B illustrates a state in which the spectacle apparatus 200 is mapped to the content view 2 after the preset time in (a). However, since the glasses device 200-3 on the left is continuously mapped to the content view 1 by transmitting a selection command from (a) to the display device 100, a viewer wearing the glasses device 200-3 on the left side may wear it. The content view 1 can be watched continuously. Meanwhile, a message object for inquiring whether to map is no longer added to the image frame of the content view 1 mapped for a preset time. Therefore, the viewer who selects the content 1 can watch the content 1 without interruption by the object when a predetermined time elapses.

In addition, when a selection command is input from the user through the input unit 240-4 of the glasses device 200-4 mapped to the content 2 in FIG. 8B, the glasses device 200-4 may display the display device ( In operation 100, the selection command may be transmitted, and the communication interface of the display apparatus 100 may continuously map the glasses device 200-4 to the content 2.

Accordingly, the user can intuitively know that the multi-view mode has been started and that the user can enter a selection command to watch specific content.

Meanwhile, the message object for inquiring whether to map with the corresponding content may be any object that can derive the mapping with the corresponding content as well as illustrated in FIG. 9. Meanwhile, in order for the user to know the remaining time for inputting a selection command for selecting content, a timer indicating the remaining time may be added to the image frame of the corresponding content and displayed.

<When an event occurs that connects the eyeglass device>

If the predefined event is an event to which the spectacles are connected, the controller 140 may control to synchronize the spectacles with one of the plurality of content views when the spectacles 200 are connected to the interface unit 160. have.

As described with reference to FIG. 9, the controller 140 may control the newly connected eyeglasses to be synchronized with a content view which is not synchronized with other eyeglasses among a plurality of content views. As another example, the controller 140 may control the content view to be synchronized with the main content view when the content view may be divided into a main content view and at least one sub content view. The main content view may be the remaining content view even when switching from the multi view mode to the single view mode. As another embodiment, as described with reference to FIG. 10, when the glasses device is connected, the controller 140 sequentially synchronizes the plurality of content views at a predetermined time interval, and when the content view selection command is received from the glasses device, the selection command is executed. The control may be performed to continuously synchronize the content view synchronized with the glasses device at the received time point.

<When an event occurs in which a control authority request command is input from a remote control device>

When the predefined event is an event in which a control authority request command is input from the remote control apparatus, when the control authority request command is input, the control unit 140 indicates an image object indicating control authority in an image frame of one of a plurality of contents. Can be added to control the display. This will be described in detail with reference to FIG. 11.

FIG. 11 is a diagram illustrating a result of displaying an image object representing a control right according to an embodiment of the present invention. FIG.

When a control authority request command is input from the remote control apparatus 300, an image processor which processes a content displayed through a content view having a current control authority among a plurality of content views of the display apparatus 100 may be included in an image frame of the corresponding content. An image object indicating a control right may be added.

In addition, the controller 140 may control to sequentially change the displayed content of the image object whenever a control authority request command is input. That is, when a control authority request command is input again from the remote control apparatus 300 in a state where an image object is added to and displayed on an image frame of any one content, an image indicating control authority on the image frame of any other content The object is added and displayed, and the content on which the image object is displayed may be sequentially changed whenever a control authority request command is input. Accordingly, the viewer can easily and intuitively check the content view with the current control authority.

Meanwhile, the control right request command refers to a user command input by a viewer who is watching content through one of the plurality of content views to control the corresponding content view. The control authority request command may be input by pressing or touching a specific button of the remote control apparatus 300, and even when a command for controlling the display device, such as a channel change or volume change button, is recognized as a control authority request command. Can be.

Referring to FIG. 11, in (a), a control authority request is input from the user remote control apparatus 300, and a star-shaped image object representing the control authority is added to the image frame of the content 2 and displayed. Since the viewer wearing the glasses device 200-6 mapped to the content 2 is watching the content 2, the viewer may check an image object indicating the control authority displayed on the display device 100, and wears the glasses device 200-6. One viewer may control content 2 through the remote control device 300. Here, controlling the content 2 means adjusting the volume corresponding to the content 2, setting the display environment for the content 2, or changing the content to another channel to watch another content when the content 2 is a broadcast program. It means things.

Meanwhile, a viewer wearing the glasses device 200-7 mapped to the content view 3 may not view the image object and may not control the content 3.

Here, when the user re-enters the control authority request command, a star-shaped image object indicating the control authority is added to the image frame of the content 3 and displayed. In FIG. 11B, the display apparatus 100 displays the content 3 to which the image object has been added, and may view the image object added to the watched content 3 wearing the eyeglasses 200-7. Viewers viewing content 2 can no longer see the image object, nor can they control content view 2.

When the control right request command is re-entered, a star-shaped image object is added to the image frame of the content 1 and displayed and may be sequentially changed whenever the control right request command is input.

The image object representing the control right may be any image that can be recognized by the viewer as well as a star-shaped image object. In addition, the present invention is not limited to the image object but may be a message object that can express control authority such as "control". In addition, if the control authority request command is not input again for a preset time, the image object may disappear after a preset time elapses.

In addition, the control authority request command may be input through the input unit 240 of the eyeglass apparatus 200 as well as the remote control apparatus 300. In this case, the content mapped to the eyeglass apparatus 200 to which the control authority request command is input is input. An image object representing control rights may be added to the view and displayed.

<When an event occurs that ends the multi-view command>

When the preset event is an event in which the multi-view end command is input, the controller may control to add a message object that notifies the end of the multi-view to the image frame of the entire contents when the multi-view end command is input and display the message object. have. This will be described in detail with reference to FIG. 12.

12 is a diagram illustrating a result of displaying a message object for notifying that a multi-view has been terminated according to an embodiment of the present invention.

When the multi-view end command is input through the remote control apparatus 300, the display apparatus 100 adds and displays a message object indicating the end of the multi-view mode to the image frame of the plurality of contents and ends the multi-view mode. Can be.

Referring to FIG. 12, when a multi-view exit command is input through the remote control apparatus 300, the display apparatus 100 ends the "multi-view mode" in an image frame of all the displayed contents (content 1, 2 and 3). Add and display a message object that notifies the end of the multi-view. Accordingly, the viewer can intuitively know that the multi-view mode ends.

Meanwhile, the multi-view end command may be input through the input unit 240 of the spectacles 200 as well as the remote control apparatus 300.

When the multi view mode ends, only the content that was displayed before the multi view mode is started is displayed and other contents are no longer displayed. Alternatively, only content having control rights may be displayed before the multi-view mode ends, and other contents may not be displayed.

Meanwhile, the object according to the above-described embodiment has been described as being a message object and an image object, but the type of the object is not limited thereto and is represented by various types of objects in response to predefined events such as icons, logos, text labels, and symbols. Can be.

In addition, the process of adding an object to an image frame in the signal processor may be specifically performed by the video processor of the image processor, or may be performed by adding an object to an image frame whose frame rate is converted by the frame rate converter. In addition, the process may be performed by an additional data processor that processes subtitles and the like. That is, if the content is composed of an image frame and before being output to the display unit, the process of adding an object may be performed at any stage.

13 is a block diagram illustrating a remote control apparatus according to an exemplary embodiment.

According to FIG. 13, the remote control apparatus 300 includes a sensing unit 310, an input unit 320, a control unit 330, and an interface unit 340.

The sensing unit 310 receives signals emitted from the plurality of glasses apparatuses 200 corresponding to the plurality of content views, respectively, detects the glasses apparatus closest to the remote control apparatus 300, and detects the sensing signal from the remote control apparatus. The control unit 300 transmits the control unit 330 to the control unit 330.

Specifically, the detection unit 310 detects the distance between the plurality of glasses device 200 and the remote control device 300, respectively, and compares the detected distance to detect the closest glasses device among the plurality of glasses device 200. can do.

In this case, the sensing unit 310 detects each of the glasses 200, a sensing method capable of sensing the distance between the remote control device 300, such as an RFID method or a magnetic sensor and each of the glasses 200. Applicable

When the sensing unit 310 operates by the RFID method among the above-described sensing methods, the sensing unit 310 compares the reception strengths of RF signals received from the plurality of eyeglasses 200, respectively, and has an RF having the maximum reception strength. The spectacle apparatus which transmits the signal may be detected as a proximity spectacle apparatus.

To this end, the spectacles 200 may further include a signal output unit 270 (see FIG. 14). 14 is a block diagram illustrating a configuration of an eyeglass device according to another embodiment of the present invention. The signal output unit 270 of the spectacle apparatus 200 may be formed of a corresponding RFID tag or other configuration according to the distance sensing method of the remote control apparatus 300. Specifically, when the remote control device 300 senses the distance of each eyeglass device by the RFID method, the signal output unit 270 may be formed of an RFID tag.

On the other hand, the input unit 320 of the remote control device 300 receives a user command. The input unit 320 may include, for example, various input interfaces including at least one or a combination of a keypad, a touch pad, a jog shuttle, a jog stick, and the like for switching a channel or an audio volume.

When a user selection command is input through the input unit 320, the controller 330 generates a control signal for controlling a content view corresponding to the detected adjacent eyeglasses among the eyeglasses 200 according to the user selection command.

The control signal may include at least one of an eyeglass device ID which is unique information of the adjacent eyeglass apparatus, content view information corresponding to the close eyeglass apparatus, and a control command for controlling the content view of the display apparatus 100.

To this end, the remote control apparatus 300 may receive information on a content view corresponding to the spectacles from the spectacles. According to an embodiment, each eyeglass device may include information on a content view in a signal output to sense a distance, and the controller 330 may generate a control signal using information on the content view of the nearest eyeglass device. have. In another embodiment, when the adjacent eyeglasses device is determined, the controller 330 may request and receive information on the content view from the adjacent eyeglasses. Meanwhile, the glasses apparatus 200 and the remote control apparatus 300 may transmit and receive information on the content view through the signal output unit 270 and the sensing unit 310 for distance sensing, but may transmit information on the content view. It may be implemented in a form including a separate interface unit (not shown) for transmitting and receiving.

The control command may include a content change command for changing the content of the content view corresponding to the glasses device in proximity to the remote control device 300, a volume adjustment command for adjusting the audio signal volume of the content, and an on-screen display on the content view. Display) may include any one of an OSD menu display command for displaying a menu, an image quality adjustment command for adjusting the image quality of an image frame displayed in the content view.

The interface unit 340 transmits a control signal generated by the controller 330 to the remote control signal receiver 170 of the display apparatus 100. In this case, the communication between the interface unit 340 and the remote control signal receiving unit 170 may use a communication method such as Bluetooth, infrared communication, Zigbee, etc., and may form a communication channel at a short distance to transmit and receive a signal. Communication may be performed according to various wireless communication methods.

According to such an embodiment, even if a user does not repeatedly input a user command to selectively control one of the plurality of content views, the user may change the position of the remote control device to change the content view mapped to the nearest eyeglass device. It can be controlled selectively. In the present exemplary embodiment, a message or an image object may be added to and displayed on the currently controllable content view.

15 is a flowchart illustrating a control method of a display apparatus according to an exemplary embodiment. Parts that overlap with the description related to the display device will be omitted and the overall flow will be described.

First, a plurality of contents are received (S1510). Specifically, a plurality of different contents are respectively received. Thereafter, an image frame is configured (S1520). In more detail, the received content is processed to form an image frame. In operation S1530, the image frame is alternately displayed. That is, a plurality of content views are configured to alternately display image frames of content corresponding to each content view.

If a predefined event occurs (S1540-Y), an operation corresponding to the generated event is performed (S1550). The predefined event may include an event in which a control command for controlling one of the plurality of content views is received from the remote control device, an event in which at least one of the plurality of contents is not synchronized with the spectacles 200, The event may include a multi-view mode start command input, an event in which a control authority request command is input from the remote control apparatus 300, an event in which a multi-view mode end command is input, and the like.

A case in which an event in which a control command for controlling one of the plurality of content views is received from the remote control device will be described with reference to FIGS. 16 to 17.

16 is a flowchart illustrating a control method of a display apparatus according to another exemplary embodiment. FIG. 17 is a flowchart illustrating a control method of a display apparatus according to another exemplary embodiment.

The receiver 110 of the display apparatus 100 receives a plurality of contents (S1610, S1705), and the signal processor 120 processes a plurality of contents, respectively, to form an image frame (S1620, S1710). The display unit 130 outputs a plurality of content views by combining image frames of respective contents (S1630 and S1715), and the synchronization signal generator 150 synchronizes the plurality of content views and the plurality of eyeglasses 200. Generate a synchronization signal for (S1640, S1720). Then, the interface unit 160 transmits a synchronization signal to the plurality of eyeglasses (S1650 and S1725). When a control command for any one content view is input in a situation in which a plurality of content views are output as described above (S1660-Y, S1730-Y), it is determined whether it is an executable operation (S1735-Y). If the corresponding operation is performed (S1737), and the execution restriction operation (S1735-N), a message indicating the input of the control command is displayed on the other content view (S1740). If the consent signal for the execution restriction operation is received from the glasses device matching the other content view (S1745-Y) or if the consent signal is not received, but no signal is received for a predetermined time (S1755-). Y) As in the case of the executable operation, an operation corresponding to the control command is performed (S1737). If the opposite signal is received (S1750-Y), the operation corresponding to the control command is not performed.

Meanwhile, when the event predefined in FIG. 15 is an event in which at least one content of the plurality of content views is not mapped to the spectacle device, and there is a content view that is not mapped to the spectacle device among the plurality of content views, A message object for inducing connection with the spectacles device is added to and displayed on an image frame of at least one content view that is not mapped.

In addition, when the predefined event is an event in which a multi-view mode start command is input, when the multi-view mode start command is input, a message object for inquiring whether to map the content to the image frame of each of the plurality of contents is provided. In addition, the contents are sequentially mapped to the spectacles. When a response to the message is received from at least one eyeglass device or the remote control device, the content displayed at the time when the response is received and the eyeglass device which transmitted the response may be mapped.

When the predefined event is an event in which a control authority request command is input from the remote control apparatus, when a control authority request command is input, an image object indicating control authority is added to an image frame of one of a plurality of contents. Display. In addition, the content on which the image object is displayed may be sequentially changed whenever a control right request command is input.

18 is a flowchart illustrating a control method of a display apparatus according to another exemplary embodiment. In particular, FIG. 18 is a flowchart illustrating a method of controlling the display apparatus when an event to which the glasses apparatus is connected occurs.

First, a plurality of contents are received (S1810). Thereafter, an image frame is configured (S1820). In more detail, the received content is processed to form an image frame. In operation S1830, a plurality of content views are output by combining the image frames.

When the spectacle device is connected to the display device, a synchronization signal for synchronizing one of the plurality of content views with the spectacle device is generated (S1840). Here, the generating of the synchronization signal may generate a synchronization signal for synchronizing the glasses device with a content view which is not synchronized with other eyeglasses among the plurality of content views. Alternatively, when the content view includes a main content view and at least one sub content view, a synchronization signal for synchronizing the spectacles with the main content view may be generated. Alternatively, a synchronization signal for sequentially synchronizing the spectacles with the plurality of content views may be generated.

In operation S1850, the generated synchronization signal is transmitted to the glasses device. When the synchronization signal for sequentially synchronizing the spectacles device to the plurality of content views is transmitted, when a content view selection command is received from the spectacle device, the synchronization may be continuously synchronized with the content view synchronized with the spectacle device at the time when the selection command is received. have. That is, the display apparatus 100 sequentially transmits synchronization signals for a plurality of content views. When the selection command is received from the spectacle apparatus 200, the display apparatus 100 continuously transmits the synchronization signal transmitted when the selection command is received. 200).

19 is a flowchart illustrating a control method of a remote control apparatus according to an embodiment of the present invention.

According to FIG. 19, the remote control apparatus 300 receives signals continuously generated from the plurality of glasses apparatuses 200 through the sensing unit 310 (S1910), and analyzes the received signals to remotely control the apparatus 300. ) And the distance between each spectacles 200 is calculated (S1920).

The controller 330 receives the calculated value from the detector 310 and selects the spectacle device that is closest to the remote control device 300 (S1930). When a user command is input through the input unit 320 (S1940), the controller 330 generates a control command through the interface unit 340 and transmits the control command to the display device 100 (S1950).

The display apparatus 100 receives a control command through the remote control signal receiving unit 170, and the controller 140 of the display apparatus 100 analyzes the received control command to control a content view synchronized with the selected eyeglass apparatus. (S1960).

As described above, in the present invention, when the user who views the content view selected by the user simultaneously through the display apparatus 100 while wearing each eyeglass device 200 controls the content view in advance, the mode is preset. Without the need for additional operations such as setting, simply bring the remote control device 300 closer to the eyeglasses worn by the user than the eyeglasses worn by others, and input the desired control command. Easily control content and audio.

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 carrying out the above-described methods may be stored in a memory such as a flash memory, a ROM (Read Only Memory), an EPROM (Erasable Programmable ROM), an Electronically Erasable and Programmable ROM (EEPROM), a hard disk, And may be stored in various types of nonvolatile recording media such as a USB memory, a CD-ROM, and the like.

Referring to FIG. 20, a polarization method will be described as another embodiment of the present invention.

20 is a diagram illustrating a situation of viewing content with a spectacle device having a polarizing lens according to an embodiment of the present invention.

In the present specification, a description has been given of a system for alternately outputting image frames of content and watching using a shutter glass. However, the description is only for better understanding of the present invention, and the present invention excludes the implementation of a polarization system. It does not mean to weaken or weaken.

The display apparatus 100 described above may further include a polarizing member 190. The polarizing member 190 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 200-11 having the horizontal polarizing lens and the spectacle apparatus 200-12 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 200-11 and 200-12 used to view the display apparatus 100 may include polarizing 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. Each eyeglass device 200-11 or 200-12 does not need a separate synchronization operation with the display device 100, and thus, economical efficiency is high, and flickering occurring during the synchronization process is also reduced. FIG. 20 illustrates a case in which a content view is viewed with the spectacle apparatus 200-11 and 200-12 having polarizing lenses suitable for the case where the image frames of the contents polarized in the horizontal direction and the vertical direction are alternately displayed. It is shown.

When the above-described processing of the control command for the content view is implemented through the polarization type display device and the spectacle device, the control command for the content view is output as an image frame of the polarized content. For example, in the case of a control command for the execution restriction operation, a message indicating the input of the control command is polarized in the same manner as the image frame of the other content and displayed together on the image of the other content view. Then, the user wearing the glasses device matching the other content view may input a response that agrees or disagrees with the control command, thereby controlling the display device.
