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 electronic book, an electronic photo frame, a kiosk,

The plurality of receiving units 110-1, 110-2, ..., and 110-n respectively receive a plurality of different contents. Specifically, each of the receiving units 110-1, 110-2, ..., and 110-n receives a content from a broadcasting station that transmits broadcast program content using a broadcast network or a web server that transmits a content file using the Internet . 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 the embodiment in which content is received from a broadcasting station, the plurality of receiving units 110-1, 110-2, ..., 110-n include a tuner (not shown), a demodulator (not shown), an equalizer And the like. On the other hand, in the embodiment of receiving content from a source such as a web server, the plurality of receiving units 110-1, 110-2, ..., 110-n may be implemented by a network interface card (not shown) . Alternatively, in the embodiment in which contents are received from the various recording medium reproducing apparatuses described above, the plurality of receiving units 110-1, 110-2, ..., 110-n are connected to an interface unit Time). As described above, the plurality of receiving units 110-1, 110-2, ..., 110-n may be implemented in various forms according to the embodiment.

Also, the plurality of receiving units 110-1, 110-2, ..., 110-n do not necessarily have to receive contents from the same type of source, and the plurality of receiving units 110-1, 110-2,. ..., 110-n may receive content from different types of sources. For example, the receiving unit 110-1 may be implemented as a form including a tuner, a demodulator, and an equalizer, and the receiving unit 110-2 may be implemented by a network interface card.

2, the display device 100 includes a plurality of receiving units. However, the plurality of receiving units may be implemented as one receiving unit. That is, one receiving unit can receive a plurality of contents.

Each of the plurality of signal processing units 120-1, 120-2, ..., and 120-n processes the contents received from the plurality of receiving units 110-1, 110-2, ..., 110-n A video frame can be configured. The signal processing unit 120 will be described in more detail with reference to FIG.

3 is a block diagram illustrating a specific configuration of a signal processing unit according to an embodiment of the present invention.

As shown in FIG. 3, the signal processing unit 1 (120-1) includes a video processing unit 121-1 and a frame rate conversion unit 122-1. Although only one signal processing unit 1 (120-1) is shown in FIG. 3, all of the other signal processing units 120-2,..., 120-n can be implemented with the same structure as in FIG.

The video processor 1 (121-1) performs signal processing on the video data included in the content received from the receiver 1 (110-1). Specifically, the video processor 1 (121-1) includes a decoder (not shown) for decoding video data and a scaler (not shown) for performing up or down scaling according to the screen size of the display unit 130 can do.

In addition, the video processing unit 121-1 may convert the video data into the data format corresponding to the frame rate conversion unit 122-1. Specifically, when the input video data is in a top-to-bottom format, the frame rate converter 1 (122-1) converts the frame into a side-by-side format The video processor 1 (121-1) can convert the video frames of each content into the side-by-side format by connecting the video frames in the horizontal direction in parallel.

The frame rate converter 1 (122-1) converts the frame rate of the content provided by the video processor 1 (121-1) to the output rate of the display device 100. [ For example, in the case where the display apparatus 100 operates at 60 Hz in the single view mode, the frame rate converter 1 (122-1) sets the frame rate of each content to 60 Hz, which is equal to the frame rate in the single view mode Can be converted. On the other hand, in the multi-view mode, the display apparatus 100 operates at an output rate of n * 60 Hz when the number of contents is n.

2, the display device 100 includes a plurality of signal processing units. However, the plurality of signal processing units may be implemented as one signal processing unit according to an embodiment of the present invention. That is, one signal processing unit can process a plurality of contents of a signal.

The display unit 130 alternately arranges and displays video frames of respective contents configured in the plurality of signal processing units 120-1, 120-2, ..., and 120-n. Specifically, the display unit 130 multiplexes the video frames of the respective contents provided in the plurality of signal processing units 120-1, 120-2, ..., and 120-n so that at least one video frame is alternately arranged, do. In some cases, the display unit 130 may perform up-scaling or down-scaling of the 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 may display image frames of the first content, video frames of the second content, ..., And displays it. The user wears the eyeglass device 200 interlocked with the display timing of the content on the display unit 130 to watch the content desired by the user. Specifically, the eyeglass unit 200 is provided with a left-eye shutter glass and a right-eye shutter glass. The left and right eye shutter glasses are alternately turned on and off when viewing 3D contents. However, when viewing a frame in which at least one image frame is alternately arranged as described above, And are turned on / off collectively according to the timing. Accordingly, the user can watch the content separately from other users.

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

Meanwhile, the above-described contents may be 2D contents or 3D contents. 3D content refers to content that enables a user to feel a stereoscopic effect by using a plurality of images representing the same object from different viewpoints.

In the case of using a plurality of 3D contents, the display unit 130 displays the left eye image included in each 3D content provided from the plurality of frame rate converting units 122-1, 122-2, ..., and 122-n, Images can be multiplexed in a predetermined layout form and alternately arranged with video frames of other contents.

Accordingly, the left eye image, the right eye image, the left eye image, the right eye image, the nth content left eye image, and the right eye image of the first contents are sequentially arranged and displayed, The left eye image and the right eye image of one content are recognized.

The control unit 140 controls operation of the display device 100 in the first half. The control unit 140 includes a plurality of receiving units 110-1 to 110-n and a plurality of signal processing units 120-1 to 120- And the display unit 130 to perform corresponding operations.

The controller 140 controls the plurality of signal processing units 120-1, 120-2, ..., and 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 the content view of one of the plurality of content views is received from the remote control device, an event in which at least one content among the plurality of contents is not synchronized with the glasses device 200 An event in which a multi-view mode start command is input, an event in which a control right request command is input from the remote controller 300, and an event in which a multi view mode end command is input.

The concrete operation of the control unit 140 according to the predefined event will be described later in each embodiment.

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

4, the display apparatus 100 includes a plurality of receiving units 110-1, 110-2, ..., 110-n, a plurality of signal processing units 120-1, 120-2, ..., 120 the display unit 130 and the control unit 140 as well as the synchronization signal generation unit 150 and the interface unit 160. [ Here, the controller 140 may control the synchronization signal generator 150 and the interface 160 to perform corresponding operations.

The synchronization signal generating unit 150 generates a synchronization signal for synchronizing the glasses device corresponding to each content according to the display timing of each content. That is, the synchronization signal generation unit 150 generates a synchronization signal for opening the shutter glass of the spectacle device at the time of displaying the image frame of each content in the multi-view mode.

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

For example, the interface unit 160 may include a Bluetooth communication module to perform communication with the spectacle device 200, and may generate a synchronization signal as a transport stream conforming to the Bluetooth communication standard and transmit the transport stream to the spectacle device.

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

The offset time is delay information from the reference time point to the on or off 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 eyeglass device turns on / off the left eye shutter glass and the right eye shutter glass when the offset time has elapsed from the reference time.

The reference time point may be a time point at which a vertical synchronization signal (i.e., a frame sync) 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 include information on a clock signal used in the display apparatus 100. [ Accordingly, upon receiving the transport stream, the spectacle device synchronizes its own clock signal with the clock signal of the display device 100, determines whether or not the offset time has elapsed from the time when the vertical synchronizing 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 sync, information for indicating the decimal point information when the period of the frame sync has a decimal point, and the like.

Hereinafter, a method of synchronizing the display device 100 and the spectacle device 200 will be described in detail with reference to the embodiments.

In one embodiment, the synchronization signal generator 150 may generate a different synchronization signal for each of a plurality of content views. In this case, the synchronization signal generator 150 may generate a synchronization signal having a different reference time point for each content view, A synchronization signal having a different offset time can be generated.

When the glasses device 200 and the display device 100 are connected, the glasses device 200 receives one of the plurality of synchronization signals from the display device 100 and is synchronized with the corresponding content view. On the other hand, when the user inputs a command for changing the content view to the glasses device 200, the glasses device 200 transmits a content view selection command to the display device 100. [ Upon receiving the content view selection command, the display device 100 transmits a synchronization signal corresponding to the changed content view to the glasses device 200, so that the content view synchronized with the glasses device 200 can be changed.

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

Meanwhile, the interface unit 160 transmits and receives a Bluetooth device address and a pin code to the eyeglass device, and performs pairing according to the 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, the Bluetooth address can be given to each of the eyeglass units in ascending order or descending order according to the order in which the eyeglass unit 200 is connected to the interface unit 160. The interface unit 160 may be configured to exclude the Bluetooth address used for connection with the glasses device 200 from the Bluetooth address search object in order to prevent other glasses devices from being connected.

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

The spectacle device can confirm whether or not the transport stream corresponds to its own spectacle device information, and can turn on or off the glass based on the time information included in the confirmed transport stream.

Although the interface unit 160 and the eyeglass device perform communication according to the Bluetooth communication method in the above-described embodiment, this is merely an example. That is, it is also possible to use a communication method such as infrared communication, Zigbee, etc. in addition to the Bluetooth method, and to perform communication according to various wireless communication methods capable of transmitting and receiving signals by forming a communication channel in a short distance .

Although the interface unit 160 has been described as communicating with a plurality of glasses devices through one communication module, the interface unit 160 may be implemented with a plurality of communication modules that individually communicate with each glasses device according to an embodiment. Alternatively, when the display device 100 supports a plurality of wireless communication methods, the interface unit 160 may include a plurality of communication modules according to respective wireless communication methods. For example, the interface unit 160 may include a plurality of communication modules according to various wireless communication methods such as Bluetooth, Zigbee, and Wifi.

Although not shown in FIG. 2, the display apparatus 100 further includes a configuration for providing audio data included in each content differently for each user when operating in the multi-view mode. That is, a demultiplexer (not shown) for separating the video data and the audio data from the contents received by the receiving units 110-1, 110-2, ..., and 110-n, (Not shown), a modulator (not shown) for modulating each decoded audio data with different frequency signals, an audio output unit (not shown) for transmitting the modulated audio data to the spectacle device, and the like . Each audio data output from an audio output unit (not shown) is provided to a user through an output means such as an earphone provided in the spectacles apparatus. Since these configurations are not directly related to the present invention, a separate illustration is omitted.

On the other hand, if the content includes additional information such as 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 the subtitles processed to be displayed through the additional data processing unit (not shown) to the corresponding video frames.

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

As described above, the synchronization signal may be received in the form of a transport stream conforming to the Bluetooth communication standard. The synchronization signal may be synchronized with the display timing of the content, so that the first shutter glass part 250 and the second shutter glass part 260 to turn on or off. The information included in the transport stream has been described above with reference to FIG. 4, and thus redundant description will be omitted.

The control unit 220 controls the operation of the spectacles apparatus 200 in the first half. In particular, the control unit 220 transmits the synchronization signal received by the interface unit 210 to the shutter glass driving unit 230 to control the operation of the shutter glass driving unit 230. That is, the control unit 220 controls the shutter glass driving unit 230 to generate a driving signal for driving the first shutter glass unit 250 and the second shutter glass unit 260 based on the synchronization signal.

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 drive the first shutter glass unit 250 and the second shutter glass unit 250 according to the display timing of one of the plurality of contents displayed on the display device 100, 260 can be opened.

The first shutter glass part 250 and the second shutter glass part 260 turn on or off the shutter glass according to a driving signal received from the shutter glass driving part 230. Specifically, the first shutter glass part 250 and the second shutter glass part 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 . Accordingly, a user wearing the spectacle apparatus 200 can view one content.

On the other hand, in the case of 3D content, the first shutter glass part 250 and the second shutter glass part 260 can alternately open and close the respective glasses. That is, the first shutter glass part 250 is opened at the timing of displaying the left eye image constituting one 3D content according to the driving signal, and the second shutter glass part 260 is opened at the timing of displaying the right eye image .

The input unit 240 receives a user command for controlling the display device 100. In particular, a selection command for selecting one of the plurality of content views can be input. To this end, the input unit 240 may include a button, a touch pad, or a toggle button for selecting a content view. When the user inputs a selection command for selecting one of a plurality of content views to the input unit 240, the interface unit 210 transmits information about the selected content view to the display device 100, Lt; RTI ID = 0.0 > a < / RTI > content view. In addition, the input unit 240 may receive a response signal to the user command or control command for controlling any one of the plurality of content views, either consent or opposite.

A process of performing an operation corresponding to an event that occurs when the display device 100 generates a predefined event based on the above description will be described in detail according to an embodiment.

<Plural contents  One of the views contents View  When an event is received 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 one of a plurality of viewers wears glasses apparatuses 200-1 and 200-2 synchronized with different content views and watches content, the user inputs a user command to control the content view viewed by the user , There may be an influence on a user viewing the content through another content view. In particular, since a plurality of users are only watching their own contents, there is a case in which the display device 100 is controlled without being conscious of other users. For example, as shown in FIG. 6, a drama is broadcast in the content viewed through one spectacles unit 200-1. However, in the content viewed through the other spectacles unit 200-2, In such a case, the user wearing the other spectacles apparatus 200-2 may unconsciously turn the power of the display apparatus 200-2 off. In this case, it affects the content view seen through the electronic eyeglass unit 200-1. Therefore, it is necessary to notify other users of the input of the control command according to the type of the control command, and to obtain the agreement of the control operation.

Here, when the control unit 140 receives a control command for controlling one of the plurality of content views, the control unit 140 may selectively display a message informing that the control command is input according to the type of the control command in another content view have. As described above, when a control command is input to the display device 100 from the spectacle devices 200-1 and 200-2 that are viewing one content view, other content views may be affected. On the other hand, depending on the control command, there may be no influence on other contents view, and in some cases, it may be negligible even if it is influenced. Accordingly, when receiving a control command from the remote control signal receiving unit 170, the control unit 140 notifies the control command through a different content view according to the type of the control command, do.

Control commands are divided into executable operations and execution-restricted operations. This is due to the influence of other content views. When no other content view is affected, it is defined as an action that can be executed in any case. On the other hand, when there is an influence on other content view, it is defined as an execution limiting operation because execution possibility depends on whether the user consents or otherwise.

An executable operation is a control command in the case where there is no influence on other content views as described above. The control command for the executable operation includes 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, an OSD menu for displaying an OSD menu on the selected content view, A display command, and an image quality adjustment command for adjusting the image quality of an image frame displayed in the selected content view.

For example, when the volume adjustment signal is input from one spectacles device, the volume control operation corresponds to an action that can be performed because the volume of the spectacles device does not affect other content views. However, the control command for controlling the output volume (master volume) of the display device 100 is an execution restricting operation because it may affect other content views. As another example, there is a content changing operation. As described above, since it is possible to view various kinds of content through one content view, changing content in one content view does not affect other content views.

The execution restricting operation is a control command when there is an influence on another content view as described above. For example, there are a power on / off control operation and an output characteristic adjustment operation of the display device. That is, as described above, a user viewing one content view may unintentionally turn the power of the display device 100 off. In this case, the other content view is no longer viewable, which corresponds to the execution limiting operation. Another example is the adjustment of output characteristics. This is mainly a control command having a dependency of the display device 100. [ For example, the screen brightness is adjusted or the reception method is changed.

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

Referring to FIG. 8, since the display device 100 distinguishes between an executable operation and an execution limiting operation, the display device 100 may further include a storage unit 180 in which control operation information classified into an executable operation and an execution limiting operation is stored.

When the control command is received from the remote control signal receiving unit 170, the control unit 140 compares the received control command with the control operation information stored in the storage unit 180 to determine whether the received control command is an executable operation, Or not.

If the control command is a control command for the above-described executable operation, the control unit 140 performs a control operation corresponding to the control command for the content view. That is, in the above-described embodiment, if the control command is to control the volume of the content view, the volume control signal is transmitted without notifying another content view. On the other hand, if the control command is a control command for the operation limiting operation, the signal processing unit 120 and the display unit 130 are controlled to display a message informing the fact of inputting the control command in another content view. That is, the signal processing unit 120 converts the message related to the control command into image data and mixes the image data with the image frame of another content view, and the display unit 130 outputs the mixed image frame to another content view. For example, when a power-off control signal is input through one content view, the message " the user of channel 1 tries to turn off power " may be displayed in another content view.

At this time, the user who views the other content view can transmit a response signal to the display device 100 to agree or disagree with the control command. In one embodiment, the spectacle device 200 may receive a signal from the user through the input unit 240 to accept or reject a control command, and may transmit an agreement signal to the display device 100 through the interface unit 210. In addition, these signals may be transmitted through the remote control device 300, or may be input directly through an input unit (not shown) located in the display device 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 with the control command is received from another spectacle apparatus matching the other content view, 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 power of the display device 100, the control unit 140 displays a message " Do you agree to turn off the power of the user of the channel 1? When a response signal to agree with the power supply turn-off is received from the interface unit 210 of another spectacles apparatus, the power of the display apparatus 100 is turned off.

On the other hand, there may be a case where no response signal is received on the display device 100 after a predetermined time passes. In this case, priority can be given to the content view having the input of the control command, so that the control operation corresponding to the control command can be performed. That is, the control unit 140 can perform a control operation corresponding to the control command if a response signal to the control command is not received from another eyeglass device that matches the other content view for a preset time from the output of the message. Alternatively, however, consideration may be given to the reception of a response signal that gives priority to another content view in consideration of the influence on other content views. In this case, no control operation corresponding to the control command is performed. In the case where no response signal is received due to a difference in each control command, if the influence on the other content view is significant, it is regarded that the opposite response signal is received. If the influence is small, It is also possible to perform a control operation corresponding to the control command.

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 plurality of content views affects the other content view. In particular, when the effect on the other content view is significant, it is informed through the other content view and the agreement of the execution is obtained, thereby enabling a more stable multi-view display.

<Plural contents  At least one of the views contents View  With glasses device Not synchronized  If an unexpected event occurs>

If it is determined that there is a content that is not mapped to the spectacle device, the control unit 140 controls to display a message object that induces a connection between the spectacle device and the content view that is not mapped to the spectacle device 200. This will be described in detail with reference to FIG.

9 is a diagram showing a result of displaying a message object for leading to a connection with a spectacle device according to an embodiment of the present invention.

The plurality of spectacle devices 200-1 and 200-2 communicate with the display device 100 using unique identification information and the spectacle devices 200-1 and 200-2 are paired with the display device 100. [ the identification information unique to the spectacle devices 200-1 and 200-2 is transmitted to the display device 100. [ In another embodiment, the Bluetooth address of the interface unit 160 used for connection with the spectacle devices 200-1 and 200-2 can be used as information for identifying the spectacle device. The communication interface unit 160 of the display device 100 transmits any one of the synchronization signals corresponding to each of the plurality of content views according to the identification information received from the spectacle devices 200-1 and 200-2 or the Bluetooth address , 200-1 and 200-2. In this process, mapping information between each content view and the spectacle device can be generated or stored.

The interface unit 160 of the display device 100 checks the mapping information indicating which of the plurality of contents is mapped to which one of the plurality of glasses according to the control of the controller 140, 1, 200-2) of the content to be mapped.

When there is content that is not synchronized with the spectacle devices 200-1 and 200-2, the spectacle device 200 of the plurality of signal processing units 120-1, 120-2, ..., and 120- The signal processing unit for processing the content that is not synchronized with the eyeglass device 200 adds a message object that induces a connection with the eyeglass device 200 to the image frame of the corresponding content, Can be displayed alternately.

In addition, when a new spectacle device is connected, the controller 140 can control the new spectacle device to be automatically synchronized with the content view that is not synchronized with the spectacle device, May be controlled so that the message object displayed in the corresponding content view disappears when the at least one eyeglass device is mapped to at least one eyeglass device.

9, the display device 100 displays the content 2, and each of the spectacle devices 200-1 and 200-2 is synchronized with the content view 1 and the content view 3, All of the shutter glasses of the first and second shutter units 200-1 and 200-2 are closed. Since the glasses that are synchronized with the content view 2 do not exist, the display device 100 can additionally display a message object " Connect glasses ", which induces connection between the content view 2 and the glasses device.

On the other hand, a viewer who wears the spectacle apparatus and views the contents 1 and 3 can not see the message object displayed on the contents 2, but a viewer who watches the display screen without wearing the spectacle apparatus displays a display screen And the message object added to the content 2 can be viewed in a superimposed state with other content images. Accordingly, a viewer who views the display screen without wearing the spectacle device can recognize that some of the currently displayed content views are displayed without being synchronized with the spectacle device.

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

On the other hand, a message object that induces connection with the eyeglass device is not only shown in FIG. 9 but also any object that can recognize that the corresponding content is not mapped with the eyeglass. For example, it could be a message that states that it is in an unmapped state, such as "The glasses are not connected," or a message that provides a concrete way to connect the glasses.

Accordingly, it is possible to intuitively know that the spectacle device is not connected to the specific content at present, without interfering with viewers watching the content in the multi-view mode, . &Lt; / RTI &gt;

<Multi View mode  When an event is input where the start command is input>

If the predefined event is an event in which the multi-view mode start command is input, the control unit 140 inquires of the image frames of the plurality of content views whether or not to synchronize with the corresponding content view Display the message object, and control each content to be sequentially mapped to the eyeglass device. This will be described in detail with reference to FIG.

10 is a diagram illustrating a result of displaying a message object inquiring whether or not to synchronize with content according to an embodiment of the present invention.

When the multi-view start command is input from the user, the display device 100 starts the multi-view mode and alternately displays a plurality of contents. Here, the plurality of signal processing units may add a message object inquiring whether or not the image frame is mapped to the image frame of each of the plurality of contents, and the display unit may alternately display each image frame to which the object is attached.

The interface unit 160 sequentially maps each of the content views to the spectacle devices 200-3, 200-4, and 200-5 connected to the display device 100. [ Here, any one content view may be mapped for a preset time, and another content view may be mapped after a predetermined time elapses. Also, the same can be performed when a plurality of spectacle glasses 200-3, 200-4, and 200-5 are connected to the display device 100. [

The interface unit 160 may map a content view displayed at the time of receiving the response and a glasses device that transmits the response, when a response to the message is received from at least one glasses device. The response to the message means a content selection command input through the input unit of the spectacle devices 200-3, 200-4, and 200-5 or the remote control device.

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

10 (b) shows a state in which the glasses device 200 is mapped with the content view 2 after a predetermined time has elapsed in (a). However, since the glasses device 200-3 on the left transmits the selection command to the display device 100 in (a) and is continuously mapped to the content view 1, the viewer wearing the glasses device 200-3 on the left side The content view 1 can be continuously viewed. On the other hand, a message object for inquiring whether or not to map is added to the image frame of the content view 1 mapped for a preset time. Therefore, the viewer who selected the content 1 can watch the content 1 without disturbance by the object after a predetermined time elapses.

8B, when a selection command is input from the user through the input unit 240-4 of the spectacle apparatus 200-4 mapped with the content 2, the spectacle apparatus 200-4 outputs the selection instruction to the display apparatus 100), and the communication interface unit of the display device 100 can continuously map the eyeglass device 200-4 to the content 2.

Thus, the user can intuitively know that the multi-view mode has been started and that the user can input a selection command to view specific contents.

On the other hand, a message object inquiring whether or not the content is mapped may be any object that can induce a mapping with the corresponding content as well as those shown in FIG. On the other hand, a timer indicating the remaining time may be added to the image frame of the content so that the user can know the remaining time for inputting the selection command for selecting the content.

<When an event is connected to the glasses device>

If the predefined event is an event to which the spectacle device is connected, the control unit 140 can control to synchronize the spectacle device with one of the plurality of content views when the spectacle device 200 is connected to the interface unit 160 have.

9, the controller 140 may control the newly connected glasses device to synchronize with the content view that is not synchronized with the other glasses devices among the plurality of content views. In another embodiment, the controller 140 may control the content view to be synchronized to the main content view if the content view can be divided into a main content view and at least one sub content view. The main content view can be a remaining content view even when switched from multi-view mode to single-view mode. 10, the controller 140 sequentially synchronizes a plurality of content views in a predetermined time interval when the glasses device is connected, and when a content view selection command is received from the glasses device, And to continuously synchronize with the content view synchronized with the spectacle device at the time of reception.

<When an event that a control permission request command is inputted from the remote control device occurs>

If the predefined event is an event in which the control authority request command is input from the remote controller, the control unit 140, when the control authority request command is input, displays the image object of the control object in the image frame of one of the plurality of contents So as to display it. This will be described in detail with reference to FIG.

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

When a control authority request command is input from the remote control device 300, the image processing unit, which processes content displayed through the content view having the current control right among the plurality of content views of the display device 100, An image object representing the control authority can be added.

In addition, the control unit 140 may control the image object to sequentially change the content to be displayed each time the control authority request command is input. That is, when the control authority request command is re-input from the remote control device 300 in a state that the image object is added to the image frame of any one of the contents, An object is added and displayed, and each time the control authority request command is input, the content in which the image object is displayed can be sequentially changed. As a result, the viewer can easily and intuitively confirm the content view having the current control right.

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

11, a control authority request is input from the user remote controller 300 and a star image object indicating control authority is added to the image frame of the content 2 and displayed. The viewer who wears the glasses device 200-6 mapped with the content 2 can view the image object indicating the control authority displayed on the display device 100 because he / she is viewing the content 2 and wears the glasses device 200-6 A viewer can control the content 2 through the remote control device 300. [ Here, the control of the content 2 means that the volume corresponding to the content 2 is adjusted or the display environment for the content 2 is set, or when the content 2 is a broadcast program, And the like.

On the other hand, the viewer wearing the spectacle device 200-7 mapped with the content view 3 can not view the image object, and can not control the content 3. [

Here, when the user re-inputs the control authority request command, a star image object indicating control authority is added to the image frame of the content 3 and displayed. 11B, the display device 100 displays the content 3 to which the image object is added, and can view the image object added to the content 3 to be watched while wearing the spectacle device 200-7. The viewer viewing the content 2 can no longer view the image object, and can not control the content view 2.

When the control authority request command is re-inputted, a star-shaped image object is added to the image frame of the content 1 and displayed, and the control authority request command can be sequentially changed each time the control authority request command is input.

On the other hand, the image object representing the control authority can be any image that can be recognized by the viewer as well as a star image object. In addition, it is not limited to an image object, and may be a message object that can express control authority such as " control ". Also, if the control authority request command is not re-input for a preset time, the image object may disappear after a predetermined time elapses.

The control authority request command may be input through the input unit 240 of the spectacle apparatus 200 as well as the remote control apparatus 300. In this case, An image object representing the control authority will be added to the view and displayed.

<When an event occurs in which a multi-view shutdown command is input>

If the preset event is an event in which a multi-view end command is inputted, the control unit can control to display a message object notifying the end of the multi-view to the video frames of all the plurality of contents when the multi-view end command is input have. This will be described in detail with reference to FIG.

12 is a diagram showing a result of displaying a message object notifying a multi-view end according to an embodiment of the present invention.

When the multiview end command is inputted through the remote control device 300, the display device 100 displays a message object indicating the end of the multiview mode to the image frame of all the plurality of contents and displays it, and ends the multiview mode .

12, when a multiview end command is inputted through the remote control device 300, the display device 100 exits the multi-view mode to the video frames of all contents (content 1, 2 and 3) to be displayed And a message object notifying the multi-view termination such as ". &Quot;. Thus, the viewer can intuitively know that the multi-view mode is ended.

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

When the multi-view mode is ended, only the content displayed before the multi-view mode is started is displayed and the other contents are no longer displayed. Alternatively, only contents having control authority before the multi-view mode is ended may be displayed and other contents may be set not to be displayed.

Meanwhile, although the object according to the above-described embodiment is described as being a message object and an image object, the type of the object is not limited thereto, and may be represented by various types of objects corresponding to predetermined events such as icons, logos, text labels, .

In addition, the process of adding an object to an image frame in the signal processing unit may be performed by a video processing unit of the image processing unit and may be performed by adding an object to an image frame whose frame rate has been converted by the frame rate conversion unit. In addition, this process may be performed in an additional data processing unit for processing a caption or the like. That is, if the content is composed of video frames and then output to the display unit, a process of adding an object at any stage may be performed.

13 is a block diagram illustrating a remote control apparatus according to an embodiment of the present invention.

13, the remote controller 300 includes a sensing unit 310, an input unit 320, a control unit 330, and an interface unit 340.

The sensing unit 310 receives the signals emitted from the plurality of spectacle glasses 200 corresponding to the plurality of content views, detects the spectacle device closest to the remote control device 300, To the control unit 330 of the control unit 300.

Specifically, the sensing unit 310 detects distances between the plurality of spectacle devices 200 and the remote control device 300, and detects the closest spectacle devices 200 among the plurality of spectacle devices 200 can do.

In this case, the sensing unit 310 senses each of the spectacles 200 by using a sensing method capable of sensing the distance between the remote control 300 and the spectacles 200, such as an RFID system or a magnetic sensor Can be applied.

When the sensing unit 310 operates in the RFID mode among the sensing methods described above, the sensing unit 310 compares the reception intensities of the RF signals received from the plurality of spectacle devices 200, The eyeglass device transmitting the signal can be detected by the adjacent eyeglass device.

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

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

The control unit 330 generates a control signal for controlling a content view corresponding to the near-sighted glasses device detected from each of the glasses devices 200 according to a user selection command, when a user selection command is input through the input unit 320. [

The control signal may include at least one of a glasses device ID, which is unique information of the nearby glasses device, content view information corresponding to the nearby glasses device, and a control command for controlling the content view of the display device 100. [

To this end, the remote control apparatus 300 can receive information on the content view corresponding to the spectacle apparatus from the spectacle apparatus. In an embodiment, each eyeglass device may include information about the content view in a signal output to sense distance, and the control 330 may generate a control signal using information about the content view of the closest eyeglass device have. In another embodiment, the control unit 330 may request and receive information on the content view from the nearby glasses device when the nearby glasses device is determined. The spectacle device 200 and the remote control device 300 may transmit and receive information about the content view through the signal output unit 270 and the sensing unit 310 for distance sensing, And a separate interface unit (not shown) for transmitting and receiving data.

The control command includes a content change command for changing the content of the content view corresponding to the eyeglass device close to the remote control device 300, a volume adjustment command for adjusting the volume of the audio signal of the content, an OSD An OSD menu display command for displaying a menu, and an image quality adjustment command for adjusting an image quality of an image frame displayed in the content view.

The interface unit 340 transmits the control signal generated by the control unit 330 to the remote control signal receiving unit 170 of the display device 100. At this time, the communication between the interface unit 340 and the remote control signal receiving unit 170 can be performed using a communication system such as a Bluetooth system, an infrared communication system, a Zigbee system, or the like, Communication can be performed according to various wireless communication methods.

According to this embodiment, even if the user does not repeatedly input a user command to selectively control one of the plurality of content views, the user can change the position of the remote control device, And can be selectively controlled. It goes without saying that, in this embodiment, a message or an image object can be added to the currently controllable content view and displayed.

15 is a flowchart illustrating a method of controlling a display device according to an embodiment of the present invention. The description overlapping with the description related to the display device will be omitted and the overall flow will be mainly described.

First, a plurality of contents are received (S1510). Specifically, each of the plurality of different contents is received. Thereafter, a video frame is formed (S1520). Specifically, each of the received contents is processed to form an image frame. Then, the image frames are alternately displayed (S1530). That is, a plurality of content views are configured and the video frames of the content corresponding to each content view are alternately displayed.

Here, if a previously defined event occurs (S1540-Y), an operation corresponding to the generated event is performed (S1550). The predefined event is an event in which a control command for controlling the content view of one of the plurality of content views is received from the remote control device, an event in which at least one content among the plurality of contents is not synchronized with the glasses device 200, An event in which a multi-view mode start command is input, an event in which a control right request command is input from the remote controller 300, and an event in which a multi view mode end command is input.

A case in which a control command for controlling a content view of one of a plurality of content views is received from the remote control apparatus occurs will be described with reference to FIG. 16 to FIG.

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

The receiving unit 110 of the display device 100 receives a plurality of contents (S1610 and S1705), and the signal processing unit 120 processes the plurality of contents to configure image frames (S1620 and S1710). The display unit 130 combines the image frames of each content to output a plurality of content views (S1630 and S1715), and the synchronization signal generation unit 150 synchronizes the plurality of content views and the plurality of spectacle devices 200 (S1640, S1720). Then, the interface unit 160 transmits the synchronization signal to the plurality of spectacle devices (S1650, S1725). When a control command for any one of the content views is input (S1660-Y, S1730-Y) in the state where a plurality of content views are outputted in this manner, (S1737). In the case of the execution restricting operation (S1735-N), a message informing the fact of the input of the control command is displayed in another content view (S1740). If no signal is received during the elapse of a predetermined period of time (S1745-Y), or if no consent signal is received (S1755- Y) operation as in the case of the executable operation (S1737). If an opposite signal is received (S1750-Y), the operation corresponding to the control command is not performed.

If an event defined in FIG. 15 is an event in which at least one of the plurality of content views is not mapped to the spectacle device, if there is a content view that is not mapped to the spectacle device among the plurality of content views, And adds a message object to the image frame of at least one unmapped content view to induce connection with the spectacle device.

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 inquiring whether or not the corresponding image frame is mapped to the corresponding image frame And sequentially maps each content to the spectacle device. And, when a response to the message is received from at least one spectacle device or a remote control device, it is possible to map the content displayed at the time of receiving the response and the spectacle device transmitting the response.

If the predefined event is an event in which the control authority request command is input from the remote control apparatus, when the control authority request command is input, an image object indicating the control authority is added to the image frame of one of the plurality of contents Display. Also, each time the control authority request command is input, the content in which the image object is displayed may be sequentially changed.

If a predefined event is an event in which a multi-view end command is input, when a multi-view end command is input, a message object notifying the end of the multi-view is added to and displayed on the video frames of all the plurality of contents.

18 is a flowchart illustrating a method of controlling a display device according to another embodiment of the present invention. Particularly, FIG. 18 is a flowchart for explaining a control method of a display device when an event to which a spectacle device is connected occurs.

First, a plurality of contents are received (S1810). Thereafter, an image frame is formed (S1820). Specifically, each of the received contents is processed to form an image frame. Then, a plurality of content views are output by combining the video frames (S1830).

When the glasses device is connected to the display device, a synchronization signal for synchronizing one of the plurality of content views and the glasses device is generated (S 1840). Here, generating the synchronization signal may generate a synchronization signal that synchronizes the glasses device with a content view that is not synchronized with another of the plurality of content views. Alternatively, if the content view includes a main content view and at least one sub-content view, a synchronization signal may be generated that synchronizes the spectacle device with the main content view. Alternatively, a synchronization signal may be generated that sequentially synchronizes the glasses device with a plurality of content views.

Then, the generated synchronization signal is transmitted to the spectacle device (S1850). When a synchronous signal for sequentially synchronizing the spectacle device to a plurality of content views is transmitted and the content view selection command is received from the spectacle device, it is possible to continuously synchronize with the content view synchronized with the spectacle device at the time of receiving the selection instruction have. That is, the display device 100 sequentially transmits synchronization signals for a plurality of content views. When a selection command is received from the glasses device 200, the display device 100 continuously transmits a synchronization signal transmitted at the time of receiving the selection command to the glasses device 200).

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

19, the remote control apparatus 300 receives signals continuously generated from the plurality of spectacle apparatuses 200 through the sensing unit 310 (S1910), analyzes the received signals, and outputs the analyzed signals to the remote controller 300 And each of the spectacle glasses 200 is calculated (S1920).

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

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

As described above, according to the present invention, when users who watch the content view selected by themselves through the display device 100 while wearing the spectacle glasses 200 control their own content view, It is possible to simply bring the remote control device 300 closer to the eyeglass device worn by the user than to the eyeglass device worn by the other person, Content and audio can be easily controlled.

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

Specifically, the code for 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.

FIG. 20 is a view showing a state of viewing a content with a spectacle lens device having a polarizing lens according to an embodiment of the present invention.

Although the present invention has been described with reference to a system in which image frames of contents are alternately output and viewed using a shutter glass, such description is only for the purpose of facilitating understanding of the present invention, Or weaken it.

The above-described display device 100 may further include a polarizing member 190. The polarizing member 190 may have a liquid crystal layer (not shown) to polarize the image. The display device 100 controls the liquid crystal layer by horizontal lines or vertical lines using driving voltages of different levels and polarizes the image of the content emitted from the display device 100 in a specific direction. At this time, the images of the polarized contents can be alternately arranged and output. For example, one content can be polarized in the horizontal direction and outputted, and then polarized in the vertical direction with respect to the other contents, and output, and this process is repeated. It is possible to view each image, that is, a content view, through the spectacle apparatus 200-11 having the horizontally polarized lens and the spectacle apparatus 200-12 having the vertically polarized lens. In another embodiment, video information of different contents may be included in different areas of one video frame. In this case, it is possible to output the polarized light in the different directions and to view different contents views through the spectacle device having the lens that coincides with the respective polarization directions.

In this case, the spectacle devices 200-11 and 200-12 used for viewing the display device 100 may include a polarizing lens coinciding with the polarization direction of the content to be viewed. Thus, each of the spectacle devices passes only the polarized image, so that the user can view only the desired content view. Since each of the spectacle devices 200-11 and 200-12 does not require a separate synchronization operation with respect to the display device 100, the spectacle glasses 200 and 200-12 have high economical efficiency and reduce blinking occurring in the synchronization process. 20 shows a case of viewing the content view with the spectacle devices 200-11 and 200-12 equipped with polarized lenses respectively corresponding to the image frames related to the contents polarized in the horizontal direction and the vertical direction are alternately displayed Respectively.

When the processing of the control command for the content view is implemented through the polarizing type display device and the spectacle device, the control command for the content view is outputted as the video frame of the polarized content. For example, in the case of the control command for the execution limiting operation, the message informing the input of the control command is polarized in the same manner as the image frame of the other contents, and is displayed together with the image of the other contents view. Then, a user wearing a spectacle device matching with another content view can input a response to agree or disagree with a control command, and the display device is controlled accordingly.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the invention as defined by the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
