Specifically, the video processing unit 1121 - 1 may include a decoder (not shown) performing decoding on video data and a scaler (not shown) zooming in or out matching the screen size of the real unit 130 .

Besides, the video processing unit 1121-1 may convert video data into a data format corresponding to the frame rate converting unit 1122-1. Specifically, when the received video data is in a top-to-bottom (top-to-bottom) format, when the frame rate converting unit 1122-1 processes frames in a side-by-side (side-by-side) format, the video processing unit 1121 -1 It is possible to convert the image frames of the respective contents into the side-by-side format by connecting them side by side in the horizontal direction.

The frame rate conversion unit 1122-1 converts the frame rate of the content provided by the video processing unit 1121-1 in matching with the output rate of the display apparatus 100. For example, in the single view mode, if the display device 100 operates at 60 Hz, the frame rate conversion unit 1122-1 may convert the frame rate of each content to 60 Hz which is the same as the frame rate of the single view mode. In addition, in the multi-view mode, when there are n contents, the display device 100 operates at an output rate of n*60 Hz.

In addition, in the description of FIG. 2 , the display device 100 includes a plurality of signal processing units, but according to an embodiment, the plurality of signal processing units may be realized as one signal processing unit. That is, one signal processing unit can process a plurality of contents.

According to circumstances, the display unit 130 may enlarge or reduce the image frame to match the screen size.

For example, for a display device of the shutter glasses method, the display unit 130 alternately arranges and displays at least each of image frames of the first content, image frames of the second content, . . . , image frames of the nth content. The user wears the eyewear device 200 in conjunction with the time when the content is displayed on the display unit 130 to watch the desired content. Specifically, the glasses device 200 includes left-eye shutter glasses and right-eye shutter glasses. Although the shutter glasses for the left eye and the shutter glasses for the right eye are turned on/off alternately when viewing 3D content, when viewing at least each of the alternately arranged frames of the respective image frames as described above, according to the content synchronized with the glasses device, The outputs are turned on/off at the same time. According to this, the user can watch the content independently from other users.

A mode in which image frames of respective contents are alternately arranged and displayed as described above may be named a multi-view mode (or, dual-view mode) or the like. When the display device 100 works in a general mode (single-view mode) that displays only one 2D content or 3D content, only one of the plurality of receiving units 110-1, 110-2, ..., 110-n can be activated to receive Unit handles content. When the user selects the multi-view mode while working in the normal mode, the display device 100 activates the remaining receiving units to process data in the above-mentioned manner.

In addition, the above-mentioned content may be 2D content or 3D content. The 3D content refers to content that enables a user to feel a three-dimensional effect by using a plurality of images representing the same object (object) from different angles of view.

The layout form of the content can be multiplexed, and can be arranged alternately with image frames of other contents.

Accordingly, the left-eye image, right-eye image of the first content, left-eye image, right-eye image of the second content, . A left-eye image and a right-eye image of one content are recognized by the glasses device 200 .

The control unit 140 controls all operations of the display device 100 . Specifically, the control unit 140 respectively controls multiple receiving units 110-1, 110-2, ..., 110-n, multiple signal processing units 120-1, 120-2, ..., 120-n, and The display unit 130 is configured to perform corresponding actions.

Also, when a predetermined event occurs, the control unit 140 may control the plurality of signal processing units 120-1, 120-2, . . . , 120-n and the display unit 130 to perform actions corresponding to the event.

Here, the predetermined events may include: an event of receiving a control instruction to control one of the plurality of content views from the remote control device, an event of at least one of the plurality of contents not being synchronized with the glasses device 200, an input of a multi-view An event of a mode start instruction, an event of receiving a control authority request instruction from the remote control device 300 , an event of receiving a multi-view mode end instruction, and the like.

The specific actions of the control unit 140 according to predetermined events will be described in several embodiments.

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

According to FIG. 4 , the display device 100 not only includes multiple receiving units 110-1, 110-2, ..., 110-n, multiple signal processing units 120-1, 120-2, ..., 120-n, The display unit 130 and the control unit 140 may further include a synchronization signal generating unit 150 and an interface unit 160 . Here, the control unit 140 respectively controls the synchronization signal generating unit 150 and the interface unit 160 so as to perform corresponding actions.

The synchronization signal generating unit 150 generates a synchronization signal for synchronizing the glasses devices corresponding to the respective contents according to the display time of the respective contents. That is, the synchronization signal generating unit 150 generates a synchronization signal to turn on the shutter glasses of the glass device at a time point when image frames of respective contents are displayed in the multi-view mode.

The interface unit 160 is connected to at least one glasses device for communication. At this time, the interface unit 160 may communicate with the glasses device in various wireless ways, transmit a synchronization signal to the glasses device, and receive a selection command from the glasses device.

For example, the interface unit 160 may be equipped with a Bluetooth communication module to communicate with the glasses device 200, and generate a synchronization signal as a transport stream based on the Bluetooth communication standard and transmit it to the glasses device.

The transport stream includes time information for turning on/off the shutter glasses of the glasses device in synchronization with the display time of the content. Specifically, the time information includes information on the bias time for turning on the shutter glasses for the left eye, the bias time for closing the shutter glasses for the left eye, the bias time for turning on the shutter glasses for the right eye, and the bias time for closing the shutter glasses for the right eye .

The offset time is delay information for each content from a set reference time point to opening or closing of the shutter glasses. That is, the glasses device turns on/off the left-eye shutter glasses and the right-eye shutter glasses when the offset time has elapsed from the reference time point.

For example, the reference time point may be a time point at which a vertical synchronization signal (ie, frame synchronization) is generated in an image frame, and information on the reference time point may be included in the transport stream. Also, the transport stream may contain information on a clock signal used in the display apparatus 100 . Accordingly, when receiving the transport stream, the glasses device synchronizes its own clock signal with the clock signal of the display device 100, and uses the clock signal to determine whether the offset time has Close the shutter glasses.

In addition to this, the transport stream may further include information on the frame synchronization period, information for marking a decimal point when the period of the frame synchronization has a decimal point, and the like.

In addition, the interface unit 160 transmits and receives a Bluetooth address, a pin code, and the like to and from the glasses device, and executes pairing based on a Bluetooth communication method.

In an embodiment, the interface unit 160 may have multiple Bluetooth addresses, and one Bluetooth address may be connected to one glasses device. At this time, according to the order in which the glasses devices 200 are connected to the interface unit 160, the Bluetooth addresses may be given to the respective glasses devices in ascending or descending order. In order to prevent the Bluetooth address already connected to the glasses device 200 from being connected to other glasses devices, the interface unit 160 may exclude the Bluetooth address from the Bluetooth address object.

When the pairing is completed, information about the glasses device (for example, original identification information of the glasses device or a Bluetooth address used for pairing, etc.) may be registered in the interface unit 160 . The interface device 160 matches information on each glasses device with a transport stream corresponding to a display time of each content, and transmits the transport stream to each glasses device based on the information acquired through pairing.

When receiving the transport stream, the glasses device confirms whether it corresponds to its own glasses device information, and may turn on or off the shutter glasses based on the time information contained in the confirmed transport stream.

Although in the above embodiments, the communication between the interface unit 160 and the eyewear device by means of Bluetooth communication is taken as an example, this is only an example. That is, in addition to the Bluetooth method, communication methods such as infrared communication and Zigbee can be used, and other wireless communication methods that form short-range communication channels and transmit and receive signals can also be used for communication.

Although in the above description, the interface unit 160 communicates with a plurality of glasses devices with one communication module, it may be configured as a plurality of communication modules that communicate with each glasses device individually according to an embodiment. Alternatively, when the display device 100 supports a plurality of wireless communication methods, the interface unit 160 may be configured to include a plurality of communication modules based on each wireless communication method. For example, the interface unit 160 may include multiple communication modules based on various wireless communication methods such as Bluetooth, zigbee, and wifi.

In addition, although omitted in FIG. 2 , the display device 100 also includes a structure for separately providing audio data included in each content according to the user when operating in the multi-view mode. That is, it may further include a demultiplexer (not shown) for separating video data and audio data from the content received by each receiving unit 110-1, 110-2, ..., 110-n, and for separating The audio decoder (not shown) that decodes the output audio data, the modulation unit (not shown) that modulates the decoded audio data into mutually different frequency signals, and sends the modulated audio data to the glasses device audio output unit (not shown), etc. Each audio data output from an audio output unit (not shown) may be provided to a user through an output device such as an earphone provided in the glasses device. Since these structures are not directly related to the present invention, they are not shown in the figures.

In addition, depending on the situation, if the content contains additional information (electronic program table, subtitles, etc.), a demultiplexer (not shown) can further separate the additional data from the content. Furthermore, the display device 100 may add subtitles or the like processed to be displayable by an additional data processing unit (not shown) to the corresponding image frame.

FIG. 5 is a block diagram illustrating the structure of a display device according to still another embodiment of the present invention.

According to FIG. 5 , the display device 100 not only includes multiple receiving units 110-1, 110-2, ..., 110-n, multiple signal processing units 120-1, 120-2, ..., 120-n, The display unit 130 and the control unit 140 may further include a remote control signal receiving unit 170 .

The remote control signal receiving unit 170 may receive a control command from the remote control device 300 . The control unit 140 can control the actions of the display device 100 according to the control instruction received by the remote control signal receiving unit 170 .

FIG. 6 is a block diagram showing the structure of an eyewear device according to an embodiment of the present invention.

In particular, the glasses device 200 in FIG. 6 is linked to a display device (100 in FIG. 2 ) that alternately displays a plurality of contents in units of image frames, and includes an interface unit 210, a control unit 220, a shutter glasses driving unit 230, and an input unit 240. , the first shutter glasses unit 250 and the second shutter glasses unit 260 .

The interface unit 210 communicates with the display device. For example, the interface unit 210 may be composed of a Bluetooth communication module, communicate with the display device 100 to receive a synchronization signal, and may transmit information about the glasses device 200 . Also, a user instruction (or control instruction) input through the input unit 240 may be transmitted to the display device.

As described above, the received synchronization signal may be in the form of a transport stream based on the Bluetooth communication standard, and may include the first shutter glass unit 250 and the second shutter glass unit 260 for opening or closing the glass device 200 in synchronization with the display time of the content. time information. The information included in the transport stream has already been described in conjunction with FIG. 4 , so repeated descriptions are omitted here.

The control unit 220 controls all operations of the eyewear device 200 . In particular, the control unit 220 transmits the synchronization signal received through the interface unit 210 to the shutter driving unit 230 to control the operation of the shutter glasses driving unit 230 . That is, the control unit 220 controls the shutter glass driving unit 230 based on the synchronous signal so that the shutter glass driving unit 230 generates a driving signal for driving the first shutter glass unit 250 and the second glass driving unit 260 .

The shutter glass driving unit 230 generates a driving signal based on the synchronization signal received from the control unit 220 . In particular, the shutter glass driving unit 230 may turn on the first shutter glass unit 250 and the second shutter glass unit 260 according to a time when one of the plurality of contents displayed on the display device 100 is displayed based on the synchronization signal.

The first shutter glass unit 250 and the second shutter glass unit 260 turn on or close the shutter glass according to a driving signal received from the shutter glass driving unit 230 . Specifically, the first shutter glasses unit 250 and the second shutter glasses driving unit 260 turn on the shutter glasses at the same time when one of the contents is displayed, and turn off all the shutter glasses when other contents are displayed. Accordingly, the user wearing the glasses device 200 can watch one content.

In addition, for 3D content, the first shutter glass unit 250 and the second shutter glass unit 260 can alternately open and close the respective glasses. That is, according to the driving signal, the first shutter glass unit 250 may be turned on when a left-eye image constituting 3D content is displayed, and the second shutter glass unit 260 may be turned on when a right-eye image is displayed.

The input unit 240 receives user instructions for controlling the display apparatus 100 . In particular, a selection instruction for selecting any one of a plurality of content views may be received. For this, the input unit 240 may be provided with a key capable of selecting a content view, a touch pad, a trigger key, or the like. When the user inputs a selection command to select a content view from a plurality of content views through the input unit 240, the interface unit 210 may transmit information about the selected content view to the display device 100, and may receive from the display device 100 a corresponding Synchronization signal for the selected content view. Also, the receiving unit 240 may receive a user instruction for controlling any one of a plurality of content views or a response signal of approval or disapproval of the control instruction.

Based on the above, when a predetermined event occurs on the display device 100 , the process of performing an action corresponding to the event will be described in detail.

<Case where an event of receiving a control instruction for controlling one of a plurality of content views occurs>

FIG. 7 is a diagram for explaining how a control command received from a remote control device affects other content views.

When multiple viewers wear glasses devices 200-1 and 200-2 that are synchronized with different content views to watch content, if one of the users inputs a user instruction to control the content view he is watching, it may affect the content of the other viewers. Content View Other users viewing content. In particular, since a plurality of users are viewing only content selected by themselves, the display device 100 may be controlled without consideration of other users. For example, as shown in FIG. 6 , when a drama is being played in the content viewed through one glasses device 200-1, and when a movie shown in the content watched through the other glasses device 200-2 ends, the other glasses device 200- 2 may unintentionally turn off the power of the display device 100. At this time, this operation will also affect the content view viewed through the former glasses device 200-1, so it is necessary to inform other users of the input of the control command according to the type of the control command, and obtain consent for the control operation.

Here, when the control unit 140 receives a control instruction for controlling one of the plurality of content views, it may selectively display a message informing the input of the control instruction on other content views according to the type of the selection instruction. . As described above, when a control command is input to the display device 100 from the glasses devices 200-1 and 200-2 viewing one content view, it also affects other content views. Conversely, depending on the type of control command, there may be cases where it does not affect other content views, or even if it does, it may be ignored. Accordingly, when a control instruction is received from the remote control signal receiving unit 170, the control unit 140 controls to notify through other content views according to the type of the control instruction or perform a control operation without notification.

Control instructions are divided into executable operations and restricted execution operations. This is based on whether it affects other views. Actions are defined to be executable in any case if they have no effect on other content views. On the contrary, when it affects other content views, whether it can be executed is determined based on whether other users agree or other conditions, so it is defined as a restricted execution operation.

As mentioned earlier, actionable actions are control instructions that do not affect other content views. The control instruction for the executable operation may include: a content change instruction for changing the content of the selected content view; a volume adjustment instruction for adjusting the volume of the audio signal of the content; An OSD menu display instruction for displaying an OSD menu; an image quality adjustment instruction for adjusting the image quality of the image frame displayed in the selected content view; and the like.

Taking the volume adjustment operation as an example, when a volume adjustment signal is received from a glasses device, even if the volume of the related glasses is controlled, it has no effect on other content views, so the volume adjustment operation is an executable operation. However, the control command to adjust the output volume (master volume) of the display device 100 may affect other content views, and thus belongs to the restricted execution operation. As another example, there is a content change operation. As mentioned above, since a plurality of kinds of content can be viewed in one content view, changing content in one content view does not affect other content views.

As mentioned above, the execution restriction operation refers to a control instruction that affects other content views. For example, a power on/off control operation and an output performance adjustment operation of a display device belong to restricted execution actions. That is, as described above, there is a possibility that the user watching one content view unintentionally turns off the power of the display device 100 . At this time, other content views will also be unavailable, so this operation is a restricted execution operation. In addition, adjusting the output performance is also a restriction execution operation. Restricted execution operations mainly refer to control commands that are dependent on the display device 100 (for example, adjusting screen brightness or changing the receiving system).

Since it is necessary to distinguish between executable operations and restricted execution operations, the display device 100 according to FIG. 8 may be provided with a storage unit 180 storing control operation information classified into executable operations and restricted execution operations, respectively.

When the remote control signal receiving unit 170 receives a control command, the control unit 140 compares the received control command with the control operation information stored in the storage unit 180, so as to determine whether the received control command is executable or restricted. operate.

When the received control instruction is a control instruction related to the aforementioned executable operation, the control unit 140 performs a control operation corresponding to the control instruction on the content view. That is, when the control instruction is the control instruction for adjusting the volume of the content view in the foregoing embodiments, other content views will not be notified and a volume adjustment signal will be issued. On the contrary, when the control command is a control command about restricting execution operations, the signal processing unit 120 and the display unit 130 are controlled to display a message informing the fact of the input of the control command to other content views. That is, the signal processing unit 120 transforms the message about the control instruction into image data and mixes it into the image frame of other content views, and the display unit 130 outputs the mixed image frame. For example, when a control signal to turn off the power is input through one content view, a message "the user of channel 1 is going to turn off the power" may be displayed in another content view.

At this time, the user watching other content views may send a response signal to the display device 100 to approve or reject the control instruction. As an embodiment, the glasses device 200 may receive a signal from the user agreeing or rejecting the control instruction through the input unit 240 , and send a signal indicating whether the user agrees or not to the display device 100 through the interface unit 210 . Moreover, it is also possible to transmit such a signal through the remote control device 300 or directly input such a signal through an input unit (not shown) on the display device 100 . In the example of receiving a signal through the input unit of the glasses device, when receiving a response signal agreeing to the control command from other glasses devices matching other content views, the control unit 140 performs a control operation corresponding to the control command, and when receiving a response signal against the control command When the response signal of the control command is received, the control unit 140 will not perform the control operation corresponding to the control command. That is, in an embodiment of turning off the power of the display unit 100, the control unit 140 displays the message "The user of Channel 1 is going to turn off the power, agree?" The interface unit 210 of the eyewear device turns off the power of the display device 100 when receiving the response signal agreeing to turn off the power.

In addition, there may be a case where the display device 100 does not receive any response signal even after a predetermined time elapses. At this time, priority may be given to the content view into which the control instruction is input, so as to execute the control operation corresponding to the control instruction. That is, the control unit 140 may perform a control operation corresponding to the control command when no response signal regarding the control command is received from other glasses devices matching the other content view within a predetermined time from the time point when the message is output. However, in contrast to this, in consideration of the impact on other content views, priority may be given to other content views, so that it may be deemed that a negative response signal has been received. At this time, no operation corresponding to the control instruction will be performed. Moreover, each control instruction can be set differently. When no response signal is received, the control instruction that has a large impact on other content views can be regarded as receiving an opposing response signal, while having little impact on other content views. The control instruction of , can be regarded as receiving the agreed response signal, so as to execute the control operation corresponding to the control instruction.

Accordingly, the execution method of the control operation can be changed according to the extent to which the control command input to one of the multiple content views affects other content views. In particular, when the influence on other content views is large, it is possible to notify and obtain consent through other content views, thereby enabling more stable multi-view display.

In addition, in the above-mentioned embodiment, when inputting the control command about restricting execution operations, inform other content views of the fact that the control command is input, and obtain consent, but may not inform other content views of the fact of input of the control command according to the situation , only execute the control operation corresponding to the control command on the content view for which the control command is input. For example, when a command to turn off the power of the display device is input, other content views may not be notified of the fact that the control command is input, but only the content view for which the command to turn off the power is input may be closed.

<Case where at least one content view among a plurality of content views is not synchronized with the glasses device occurs>

When the control unit 140 determines that there is content that is not synchronized with the glasses device, it controls to add and display a message object for guiding establishing a connection with the glasses device to the content view that is not synchronized with the glasses device 200 . This will be specifically described with reference to FIG. 9 .

FIG. 9 is a diagram illustrating a result of displaying a message object guiding to establish a connection with a glasses device according to an embodiment of the present invention.

A plurality of glasses devices 200-1, 200-2 communicate with the display device 100 by using the original identification information respectively. When the glasses devices 200-1, 200-2 and the display device 100 are paired, The original identification information of will be sent to the display device 100 . As another example, the Bluetooth address of the interface unit 160 used when establishing a connection with the glasses devices 200-1, 200-2 may be used as information for identifying the glasses devices. The interface unit 160 of the display device 100 sends any one of the synchronization signals corresponding to each of the plurality of content views to the glasses device 200- 1. 200-2. During this process, synchronization (mapping) information of each content view and the glasses device may be generated or stored.

Here, the interface unit 160 of the display device 100 checks the synchronization information indicating which glasses device each of the plurality of contents is synchronized with according to the control of the control unit 140, thereby making it possible to determine whether any of the plurality of contents is not synchronized with the glasses device 200-1, 200-2 Contents of synchronization (mapping).

Also, when there is content that is not synchronized with the glasses device 200-1, 200-2, the plurality of signal processing units 120-1, 120-2, ..., 120-n processes the content that is not synchronized with the glasses device 200. The signal processing unit of the content adds a message object guiding the establishment of a connection with the glasses device 200 to the image frame of the related content, and the display unit may alternately display the image frame added with the message object and the image frame of other content.

Moreover, when a new glasses device is connected, the control unit 140 may control the new glasses device to automatically synchronize with a content view that is not synchronized with the glasses device, when the relevant content view is based on a message object that guides to establish a connection with the glasses device and at least When a glasses device is synchronized, the control unit 140 controls to make the message object displayed in the relevant content view disappear.

According to FIG. 9 , display device 100 displays content 2, glasses devices 200-1, 200-2 are synchronized with content view 1 and content view 3 respectively, and when content 2 is displayed, the shutters of glasses devices 200-1, 200-2 Glasses are turned off. Since there are no glasses synchronized with the content view 2, the display device 100 may display a message object (“Please connect the glasses”) to the content view 2 to guide the connection between the content view 2 and the glasses device.

In addition, viewers who wear glasses to watch content 1 and content 3 cannot see the message object displayed on content view 2, but users who do not wear glasses to watch the display screen can see the display screen in which multiple content images overlap, and can see A message object added to content view 2 that overlaps with other content images. Accordingly, viewers viewing the display screen without wearing the glasses device can know that a part of the currently displayed content view is being displayed without being synchronized with the glasses device.

Here, when a new glasses device is connected to the display device 100, it can be automatically synchronized with the content view 2 that is not synchronized (mapped) with the existing glasses devices 200-1, 200-2.

In addition, besides the message object shown in FIG. 9 , the message object that guides the connection with the glasses device may be any object that can know the fact that the related content is not synchronized with the glasses. For example, a message such as "the glasses are not connected" informing that it is in an unsynchronized state, or a message providing a specific method for connecting the glasses, etc.

Accordingly, in the multi-view mode, the viewer who is watching the content is not hindered, and the fact that the current specific content is not connected to the glasses device can be intuitively informed, and the content that has not been connected to the glasses device can be more conveniently combined with the new glasses device. to sync.

<When an event of inputting a multi-view mode start command occurs>

When the predetermined event is an event of inputting a multi-view mode start command, if the multi-view mode start command is input, the control unit 140 displays an inquiry whether the content view is related to the relevant content view in the image frame of each content view in a plurality of content views. Synchronized message object, and can be controlled so that each content is synchronized to the glasses device sequentially. This will be described in detail with reference to FIG. 10 .

FIG. 10 is a diagram illustrating a result that a message object asking whether to synchronize with content is displayed according to an embodiment of the present invention.

When the user inputs a command to start the multi-view mode, the display device 100 starts the multi-view mode to alternately display a plurality of contents. Here, the plurality of signal processing units add a message object inquiring whether to synchronize with related content in each image frame of a plurality of contents, and the display unit may alternately display each image frame added with the object.

Also, the interface unit 160 sequentially maps each content view to the glasses devices 200 - 3 , 200 - 4 , 200 - 5 that establish a connection with the display device 100 . Here, any content view may be mapped for a predetermined time, and other content views may be mapped after the predetermined time has elapsed. Furthermore, the same execution can be performed when a plurality of glasses devices 200 - 3 , 200 - 4 , and 200 - 5 are connected to the display device 100 .

In addition, when the interface unit 160 receives a response to a message object from at least one glasses device, a content view displayed at a time point when the response signal is received may be synchronized with the glasses device that transmitted the response message. The response on the message object refers to a content selection instruction input through the input unit of the glasses apparatus 200-3, 200-4, 200-5 or the remote control apparatus.

Referring to (a) of FIG. 10 , the display device 100 alternately displays contents 1 , 2 , and 3 , and is currently displaying an image frame of content 1 . A message object "To view this screen, please press the button" is added to the image frame of each content. In addition, the plurality of eyewear devices 200-3, 200-4, and 200-5 are all synchronized with the content 1 . At this time, when a selection command for selecting the currently synchronized content 1 is input through the input unit 240-3 of the left glasses device 200-3, the left glasses device 200-3 sends the selection command to the display device 100 In other words, the interface unit of the display device 100 may continue to synchronize the left glasses device 200 - 3 with the content 1 when the predetermined time interval has elapsed.

(b) of FIG. 10 shows a state in which the glasses device 200 is synchronized with the content view 2 after a predetermined time elapses in (a). However, since the left glasses device 200-3 sends a selection command to the display device 100 in (a) to continue to synchronize with the content view 1, the viewer wearing the left glasses device 200-3 can continue to watch the content 1. In addition, no message object asking whether to synchronize or not will be added to the content view 1 that has been synchronized within a predetermined time. Therefore, the viewer who has selected the content 1 watches the content 1 without being disturbed by the object of the message when the predetermined time has elapsed.

Moreover, in (b) of FIG. 10 , when the user's selection command is input through the input unit 240-4 of the glasses device 200-4 synchronized with the content 2, the glasses device 200-4 sends the selection command to the display device 100, and the display device The interface unit of 100 can make the glasses device 200-4 continue to synchronize with the content 2.

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

In addition, the message object inquiring whether to synchronize with related content is not limited to that shown in FIG. 9 , and any object that can guide synchronization with related content can be used. In addition, a timer representing the remaining time may also be added to the image frame of the relevant content for display, so that the user can input the remaining time of the selection instruction when selecting the content.

<When the event of receiving a control authority request command from the remote control device>

When the predetermined event is an event of receiving a control authority request instruction from the remote control device, if the control authority request instruction is received, the control unit 140 controls to add a symbol indicating the control authority on the image frame of one of the plurality of contents. Graphics objects are displayed. Hereinafter, it will be described in detail with reference to FIG. 11 .

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

When receiving a control authority request instruction from the remote control device 200, the image processing unit for processing the content displayed through the content view currently having the control authority among the plurality of content views may add a graphic representing the control authority on the image frame of the relevant content object.

Moreover, the control unit 140 may control to sequentially change the content of the displayed graphic object each time the control authority request command is received. That is, in the state where a graphic object is added to an image frame of a certain content and is displayed, if the remote control device 300 receives a control authority request command again, it will add a graphic object indicating the control authority to an image frame of another certain content. Graphic objects are displayed, and the content of the displayed graphic objects can be sequentially changed each time a control authority request instruction is received. Accordingly, the viewer can easily and intuitively confirm the content view that currently has control authority.

In addition, the control permission request instruction refers to a user instruction input by a user viewing content through a certain content view in order to control a related content view. Such a control authority request command is input by pressing or touching a specific key of the remote control device 300, and can also be recognized as a control authority request command when a command for controlling the display device such as changing a channel or changing the volume is input.

Referring to (a) of FIG. 11 , upon receiving a control authority request from the remote control device 300 , a star-shaped graphic object representing the control authority is added and displayed in the image frame of content 2 . Since the viewer wearing the glasses device 200-6 synchronized with the content 2 watches the content 2, the graphic object representing the control authority displayed on the display device 100 can be confirmed, and the viewer wearing the glasses device 200-6 can control it through the remote control device 300. content2. Here, controlling the content 2 refers to adjusting the volume corresponding to the content 2, setting a display environment related to the content 2, changing to another channel to watch other content when the content 2 is a broadcast program, and the like.

In addition, the viewer wearing the glasses device 200-7 synchronized with the content view 3 will not be able to see the graphical objects, and will not be able to control the content view 3 .

Here, when the user inputs the control authority request command again, a star-shaped graphic object representing the control authority is added to the image frame of the content 3 . In (b) of FIG. 11 , the display device 100 displays the content 3 to which the graphic object is added, and the viewer wearing the glasses device 200-7 can see the graphic object added to the content 3 . Viewers watching Content 2 will no longer be able to see graphical objects, nor will they be able to control Content View 2.

When the control authority request command is input again, the image frame of the content 1 will be displayed with a star-shaped graphic object added thereto, so that it can be changed sequentially every time the control authority request command is input.

In addition, the graphic object representing the control authority is not limited to a star-shaped graphic object, and any graphic that can be recognized by the viewer may be used. Moreover, it is not limited to graphic objects, and message objects such as "control" that can represent control rights can be used. Also, if the permission request instruction is not received again within a predetermined time, the graphic object may be made to disappear after the predetermined time has elapsed.

Moreover, the control permission request command can be input not only through the remote control device 300, but also through the input unit 240 of the glasses device 200. At this time, when receiving the control permission request command, the content view synchronized with the glasses device 200 is added. Graphics objects are displayed.

<When an event of receiving a multi-view end command occurs>

When the predetermined event is the event of receiving a multi-view end instruction, if the multi-view end instruction is received, the control unit may control to add a message object that informs the end of the multi-view to all image frames of the multiple contents and to display. Hereinafter, this will be described in detail with reference to FIG. 12 .

FIG. 12 is a diagram illustrating a result that a message object notifying the fact that a multi-view ends is displayed according to an embodiment of the present invention.

When receiving a multi-view end command from the remote control device 300 , the display device 100 adds and displays a message object notifying the end of the multi-view mode to all image frames of the plurality of contents, thereby ending the multi-view mode.

Referring to FIG. 12 , when receiving a multi-view end command from the remote control device 300, the display device 100 adds a notification such as "end the multi-view mode" to the image frames of all displayed contents (content 1, 2, 3). The message object of the fact that the multiview ends and displays. Accordingly, the user can intuitively know the fact that the multi-view mode is about to end.

In addition, the multi-view end instruction may be input not only through the remote control device 300 but also through the input unit 240 of the glasses device 200 .

When multi-view mode ends, only the content that was displayed before multi-view mode started is displayed, and no other content is displayed. Alternatively, it can be set to only display content that has control rights until the end of multi-view mode, and no other content will be displayed.

In addition, the objects in the above embodiments are message objects and graphic objects, but the types of objects are not limited thereto, and various forms of objects corresponding to predefined events such as icons, signs, text labels, and signs can be used.

Moreover, the process of adding the object to the image frame is specifically performed by the video processing unit in the signal processing unit, and may be performed by adding the object to the image frame whose frame rate has been converted by the frame rate converting unit. Also, an additional data processing unit for processing subtitles and the like can also perform such a process. That is, the process of adding an object may be performed at any step as long as the content is constituted as an image frame and before output to a display unit.

In addition, when content views A and B are output in the multi-view mode, when the user watching content A inputs a multi-view end command for content view A, the display device 100 may switch to the single-view mode. At this time, the display device 100 may continue to output the content output in the content view B that has not received the multi-view end instruction in the single-view mode. Moreover, when switching to the single-view mode, the user does not need to continue to wear the glasses device, and the display device 100 can add and display a message object such as "Multi-view mode has ended, please take off the glasses device" informing that the glasses device can be taken off. However, if the content output in the content view B is 3D content, it may be necessary to continue wearing the glasses device in order to watch the 3D content. At this time, a message object such as "multi-view mode has ended and will be switched to 3D mode" may be added to inform that the single-view 3D mode has been switched.

In other embodiments, an interface may be provided, that is, when the multi-view mode ends, one content view to be displayed in the single-view mode may be selected from multiple content views.

Although the preferred embodiments of the present invention have been shown and described above, it is obvious that the present invention is not limited to the above-mentioned specific embodiments. Various changes may be made by those skilled in the art, and such changes should not be construed as departing from the technical idea or outlook of the present invention.
