BEST MODE FOR CARRYING OUT THE INVENTION

[47] A detailed reference will now be made to exemplary embodiments, examples of which are illustrated in the accompanying drawings, with reference numerals referring to like elements throughout the description. Exemplary embodiments are described below with reference to the drawings.

[48] FIG. 1 is a diagram of a display system in accordance with an exemplary embodiment.

[49] The display system of FIG. 1 includes a display device 100, a glasses device 200, and a remote control device 300.

[50] The display device 100 receives and alternately displays a plurality of content variations through a plurality of content representations. The display device 100 generates synchronization signals in accordance with the respective representations of the content and sends one of the generated synchronization signals to each of the devices 200-1 and 200-2 points.

[51] The device 200-1 and 200-2 points receive the corresponding synchronization signals from the display device 100 and open the gates of the glasses in accordance with the received corresponding synchronization signal. Therefore, the viewer wearing the device 200-1 points can watch specific content from a variety of content options displayed in the content presentation synchronized (coordinated) with the device 200-1 points. Each of the device 200-1 and 200-2 points may also include an input button 240-1 or 240-2, respectively. The input buttons 240-1 or 240-2 may be used to control the content, the display device 100, the respective glasses devices 200-1 and 200-2 and / or the remote control device 300. In an aspect of an exemplary embodiment, input buttons 240-1 or 240-2 may be used to change the presentation of the content of their respective glasses device.

[52] The remote control device 300 receives and sends a user command to the display device 100 to control the display device 100. The remote control device 300 detects the closest of the glasses devices 200-1 and 200-2 and sends a control command to control the presentation of content synchronized with the respective glasses device. Alternatively, the display device may be associated with one of the device 200-1 and 200-2 points by setting or entering a user command in the remote control device 100 display and / or one of the devices 200-1 and 200-2 points.

[53] Here, when image frames are alternately distributed and displayed, the content representation reflects a group of content image frames visible to a user wearing the device 200-1 and 200-2 points. However, the presentation of the content is different from the content. For example, when a viewer wearing a 200-1 glasses device synchronized with a specific presentation of content 1 switches the TV channel while watching content A or watches content C while playing another DVD content, the content changes from A to C, but the content view 1 is not is changing. That is, the presentation 1 of the content is a concept beyond the organization of the content, and the content A and C are similar to the channels for presenting 1 content.

[54] As shown in FIG. 1, the display device 100 alternately displays the first content and the second content using a plurality of representations of the content. The first device 200-1 points receives a synchronization signal corresponding to the first presentation of the content, and opens the shutters of the glasses when the first content is displayed, and the viewer wearing the first device 200-1 points receives the synchronization signal corresponding to the second presentation of the content, and opens the shutters of the glasses, when the second content is displayed, and the viewer wearing the second device 200-2 points can watch the second content.

[55] While the display device 100 of FIG. 1 displays two separate content variants and is connected to two glasses 200-1 and 200-2 devices corresponding to two content representations, it is understood that one or more other exemplary embodiments is not limited to this. For example, in accordance with one or more other exemplary embodiments, the display device 100 may display three or more content options through three or more presentations of content and may be connected to three or more glasses devices.

[56] The display device 100 may communicate with the device 200 points and the device 300 remote control using various wireless technologies, such as Wi-Fi, Bluetooth, the standard of the Association for data transmission in the infrared range (IRDA), radio frequency (RF) , IEEE 802.11, WLAN, HR WLAN, UWB, LR WPAN, and IEEE 1394.

[57] FIG. 2 is a block diagram of a display device 100 in accordance with an exemplary embodiment.

[58] With reference to FIG. 2, the display device 100 includes at least one receiver (eg, a plurality of receivers 110-1 to 110-n), a plurality of signal processors 120-1 to 120-n, a display unit 130 (eg, a display), and a controller 140. The display device 100 can be implemented using various devices, including TV, mobile phone, PDA, laptop, monitor, tablet PC, e-book, digital photo frame, kiosk, smart device, etc.

[59] At least one receiver (for example, a plurality of receivers 110-1 to 110-n) receives a lot of different content. For example, each of the plurality of receivers 110-1 to 110-n receives broadcast program content from a broadcast station using a broadcast network or receives a content file from a web server via the Internet. Receivers 110-1 to 110-n may receive content from various players with a recording medium that are integrated in or connected to the display device 100. A player with a recording medium refers to a device that reproduces content stored on various recording media, such as a CD, DVD, hard disk, Blu-ray discs, memory cards, USB memory, etc.

[60] When content is received from the broadcast station, receivers 110-1 to 110-n may include a tuner (not shown), a demodulator (not shown), and an equalizer (not shown). Conversely, when content is received from a source such as a web server, receivers 110-1 to 110-n can be implemented as a network interface card (not shown). When content is received from various players with a recording medium, receivers 110-1 to 110-n may be implemented as an interface unit (e.g., interface, input, etc .; not shown) connected to the player with the recording medium. As such, receivers 110-1 to 110-n can be implemented in various ways.

[61] Furthermore, it is understood that receivers 110-1 to 110-n do not necessarily receive content from sources of the same type and can receive content from sources of different types. For example, the first receiver 110-1 may include a tuner, a demodulator, and an equalizer, and the second receiver 110-2 may include a network interface card.

[62] In addition to this, in FIG. 2, it is explained that the display device 100 includes a plurality of receivers, but the display device 100 may include only one receiver, depending on exemplary embodiments. That is, a single receiver may receive multiple content options. The signal processors 120-1 to 120-n can generate image frames by processing the content received by the receivers 110-1 to 110-n. The signal processor 120 is discussed in more detail with reference to FIG. 3.

[63] FIG. 3 is a block diagram of a signal processor 120 in accordance with an exemplary embodiment.

[64] As shown in FIG. 3, the first signal processor 120 includes a first video processor 121-1 and a frame rate converter 122-1. Although only the first signal processor 120-1 is shown in FIG. 3, the same or similar to FIG. 3, the structure can be applied to other signal processors 120-1 to 120-n.

[65] The first video processor 121-1 processes the video data in the content received from the first receiver 110-1. More specifically, the first video processor 121-1 may include a decoder (not shown) for decoding the video data and a scaler (not shown) for zooming in or out on the video data in accordance with the screen size of the display unit 130.

[66] In addition, the first video processor 121-1 may convert the video data into format data corresponding to the first frame rate converter 122-1. For example, when the input video data is in the top-down format, and the first frame rate converter 122-1 processes the frame in the side-by-side format, the first frame frequency converter 122-1 can convert the frames of the content images to the side-by-side format by arranging image frames side by side in the horizontal direction.

[67] The first frame rate converter 122-1 converts the frame rate of the content output from the first video processor 121-1 to the output frequency of the display device 100. For example, when the display device 100 operates at 60 Hz in a single presentation mode, the first frame rate converter 122-1 may convert the frame rate of each content to 60 Hz, as in the frame rate of a single presentation mode. As for the n-th (for example, the second, when n = 2) content representations in the multi-representation mode, the display device 100 may operate at an output frequency of n * 60 Hz. The display device can operate in each mode with a single presentation at frequencies other than 60 Hz.

[68] Meanwhile, in FIG. 2, it is explained that the display device includes a plurality of signal processors, however, instead, the display device may include only one signal processor. That is, a single signal processor can process multiple content options.

[69] The display unit 130 alternately positions and displays frames of content images generated by signal processors 120-1 to 120-n. More specifically, the display unit 130 performs multiplexing to alternately position and display the frames of the content images output from the signal processors 120-1 to 120-n at least one after the other. In some cases, the display unit 130 may enlarge or reduce the frame of the content image in accordance with the screen size.

[70] For example, in a display device such as shutter glasses, the display unit 130 alternately positions and displays an image frame of the first content, an image frame of the second content, ... and an image frame of the nth content at least one after another. The user can watch the content intended for him / her by putting on the device 200 points, which works in concert on the timing of the display of content with the block 130 display. More specifically, the device 200 points includes a shutter glasses left eye and shutter glasses right eye. The shutter of the left eye glasses and the shutter of the right eye glasses alternately open and close when viewing 3D content. Alternatively, when at least one frame of the image is alternately positioned and displayed, the shutter of the left eye glasses and the shutter of the right eye glasses open and close together in accordance with the timing of the output of the content synchronized with the device 200 points. Therefore, the user can watch the content separately from other users.

[71] Essentially, a mode for sequentially positioning and outputting frames of content images may be referred to as a multi-view mode (or a dual-view mode). In the normal mode (or single-view mode) for displaying both two-dimensional (2D) content and 3D content, the display device 100 can process the content by activating only one of the receivers 110-1 to 110-n. When the user selects a multi-view mode in the normal mode, the display device 100 can process the data by activating one or more receivers 110-1 to 110-n.

[72] Meanwhile, the content may be 2D content or 3D content. 3D content gives the user the opportunity to feel the depth using multiple images representing the same object from different angles.

[73] When multiple variants of 3D content are used, the display unit 130 may multiplex images for the left eye of 3D content provided by the plurality of frame frequency converters 122-1-122-n based on a predetermined location, and arrange them in turn with the image frames of another content.

[74] Therefore, the image for the left eye and the image for the right eye of the first content, the image for the left eye and the image for the right eye of the second content, ... and the image for the left eye and the image for the right eye of the nth content are arranged and displayed one after another friend. The user perceives the image for the left eye and the image for the right eye of one content through the device 200 points.

[75] The controller 140 controls the operations of the display device 100. More specifically, the controller 140 controls the receivers 110-1 to 110-n, the signal processors 120-1 to 120-n, and the display unit 130 to perform the corresponding operations.

[76] When a predetermined event occurs, the controller 140 may control the signal processors 120-1 to 120-n and the display unit 130 in accordance with this event.

[77] Here, a predetermined event may include an event of receiving a control command for controlling one of the content representations from the remote control device 300, an event of the lack of synchronization of at least one of the content representations with the device 200 points, an input event of a multi-view mode launch command , an event of inputting a command request a control right from a remote control device 300, an event of inputting a command to terminate a mode with many representations, etc.

[78] The operations of the controller 140 in accordance with a predetermined event will be explained in detail below.

[79] FIG. 4 is a block diagram of a display device 100 in accordance with an exemplary embodiment.

[80] With reference to FIG. 4, the display device 100 includes a plurality of receivers 110-1 to 110-n, a plurality of signal processors 120-1 to 120-n, a display unit 130, a controller 140, a synchronization signal generator 150, and an interface unit 160. Here, the controller 140 may control the clock generator 150 and the interface unit 160 to perform their respective functions.

[81] The synchronization signal generator 150 generates a synchronization signal for synchronizing the device 200 points with the corresponding content in accordance with the timing of the content display. That is, the synchronization signal generator 150 generates a synchronization signal for opening the shutter points of the device 200 points at the time point of the display for the image frame of the content in a mode with multiple representations.

[82] The interface unit 160 communicates with at least one device 200 points. Thus, the interface unit 160 can send a synchronization signal to the device 200 points and receive a selection command from the device 200 points through communication with the device 200 points in accordance with any of various wireless circuits.

[83] For example, the interface unit 160 may include a Bluetooth communication module for communicating with the device 200 points, generate a synchronization signal as a transport stream in accordance with the Bluetooth communication standard and send the transport stream to the device 200 points.

[84] The transport stream transported from the interface unit 160 to the glasses device 200 includes offset time information for opening or closing the shutters of the glasses of the glasses device in synchronization with a reference point in time and timing the content display. More specifically, the time information may include information about at least one of a left shutter opening bias, a left shutter closing bias, a right shutter opening bias, and a right shutter closing bias of the device 200 points.

[85] Offset is information about the delay from the reference point in time to the time the shutter of the glasses opens or closes, and it can vary depending on the frame rate of the display device or the number of content presentations. That is, when the offset time period elapses from the reference time, the device 200 points opens or closes the left shutter of the glasses and the right shutter of the glasses.

[86] Furthermore, the reference point in time may be a point in time when a vertical synchronization signal (ie, frame synchronization) is generated in the image frame. The transport stream may include information about the reference point in time, and also include information about the clock signal used in the display device 100. Thus, the device 200 points, when receiving a transport stream, can synchronize its clock signal with the clock signal of the display device 100, and open or close the gates of the glasses by determining, using the clock signal, when the offset has passed since the vertical synchronization signal.

[87] In addition, the transport stream may further include information on a frame synchronization cycle and decimal point information if the frame synchronization cycle has a decimal point.

[88] The following is a specific explanation of a method for synchronizing a display device 100 and a glasses device 200 in accordance with various exemplary embodiments.

[89] According to an exemplary embodiment, the synchronization signal generator 150 may generate a different synchronization signal for each of a plurality of content representations, in which case the synchronization signal generator 150 may generate a synchronization signal having different reference times for each content representation, or a signal synchronization having the same reference point in time and different bias time.

[90] When the point device 200 and the display device 100 are connected to each other, the point device 200 receives one of a plurality of synchronization signals from the display device 100 and synchronizes with the corresponding content presentation. Meanwhile, if the user entered a command into the device 200 points to change the presentation of the content, the device 200 points transmits a selection command to select the presentation of the content in the display device 100. When the display device 100 receives a content presentation selection command, it can transmit a synchronization signal corresponding to the changed content presentation to the glasses device 200, thereby changing the content presentation synchronized with the glasses device 200. For example, a display device may receive a content presentation selection command from one of a plurality of glasses devices and transmit a synchronization signal corresponding to the selected content presentation to a glasses device that sends a content presentation selection command.

[91] In accordance with another aspect of an exemplary embodiment, the clock signal generator 150 may generate only one clock signal, which is used as a reference. Here, this synchronization signal, which is used as a reference, may be a synchronization signal that corresponds to the main content representation of the plurality of content representations. When the device 200 points and the display device 100 are connected to each other, the device 200 points receives a synchronization signal, which becomes a reference, from the device 100 display and synchronizes with the corresponding presentation of the content. Here, if the user entered a command for changing the presentation of the content in the device 200 points, the device 200 points can simply change the synchronization of the synchronization signal, which becomes the reference, and synchronize with another representation of the content.

[92] Meanwhile, the interface unit 160 may pair based on the Bluetooth communication scheme by transmitting the Bluetooth address and PIN code to and from the device 200 points.

[93] According to an exemplary embodiment, the interface unit 160 may include a plurality of Bluetooth addresses, each of which may be associated with one eyeglass device. Here, a Bluetooth address can be assigned to each device of the glasses in ascending or descending order, in accordance with the order in which the device 200 points is connected to the block 160 of the interface. For a Bluetooth address that is already used to connect with the device 200 points, the block 160 of the interface may set an exception to prevent the binding of the already used Bluetooth address with another device points.

[94] When pairing is completed, information related to the device 200 points, for example, the identification information of the device 200 points or the Bluetooth address used for pairing, can be registered in block 160 of the interface. The interface unit 160 matches the information of the device 200 points with the transport stream corresponding to the timing of the display of content, and sends the transport stream to the device 200 points based on the information obtained by pairing.

[95] By accepting the transport stream, the device 200 points can determine whether the transport stream matches its information device points, and open or close the glasses in accordance with the information about the time of the transport stream.

[96] In the present exemplary embodiment, the interface unit 160 and the eyeglass device 200 communicate with each other in accordance with the Bluetooth communication scheme, this is an example. However, it is understood that one or more exemplary embodiments is not limited to this. For example, in accordance with one or more other exemplary embodiments, the interface unit 160 and the eyeglass device 200 may use other communication schemes, such as infrared and Zigbee, and various wireless communication schemes for transmitting and receiving signals by constructing a short-range communication channel.

[97] It is explained that the interface unit 160 communicates with a plurality of glasses devices using a single communication module, but depending on exemplary embodiments, a plurality of communication modules that communicate with each of the glasses devices individually can be proposed. Alternatively, the interface unit 160 may be configured to include a plurality of communication modules in accordance with each wireless communication method, in case the display device 100 supports a plurality of wireless communication methods. For example, the interface unit 160 may include a plurality of communication modules in accordance with various wireless communication methods, such as Bluetooth, Zigbee, Wi-Fi, etc. In this case, each of the device 200 points can communicate with the display device using different communication modules that are supported by the respective device points.

[98] Although not shown in FIG. 2, the display device 100 may further include a component for providing audio data from the content for each user in a multi-presentation mode in a different way. That is, the display device 100 may further include a demultiplexer (not shown) for separating video and audio data from content received at the receivers 110-1 to 110-n, an audio decoder (not shown) for decoding the separated audio data, a modulator (not shown) for modulating decoded audio data to other frequency signals, and a sound output unit (not shown) for sending modulated audio data to the device 200 points. The output of audio data from an audio output unit (not shown) is provided to the user by an output device such as headphones in the device 200 points.

[99] Meanwhile, in some cases, when the content includes additional information, such as an electronic program schedule (EPG) or subtitle information, a demultiplexer (not shown) may further separate these additional data from the content. The display device 100 may add subtitles processed for display by an additional data processor (not shown) in the corresponding image frame.

[100] FIG. 5 is a block diagram of a display device 100 in accordance with an exemplary embodiment.

[101] With reference to FIG. 5, the display device 100 includes a plurality of receivers 110-1 to 110-n, a plurality of signal processors 120-1 to 120-n, a display unit 130, a controller 140, and a remote control signal receiver 170.

[102] The remote control signal receiver 170 may receive a control command from the remote control device 300. The controller 140 may control the display device 100 in accordance with a control command received from the remote control signal receiver 170.

[103] FIG. 6 is a block diagram of a device 200 points in accordance with an exemplary embodiment.

[104] The device 200 points from FIG. 6 interacts with the display device 100 of FIG. 2, which alternately displays a plurality of content based on image frames, and includes an interface unit 210, a controller 220, a glasses shutter drive unit 230 (e.g., a glasses shutter drive, etc.), an input unit 240 (e.g., input, button input, etc.), block 250 of the first shutter of glasses (for example, the first shutter of glasses, etc.) and block 260 of the second shutter of glasses (for example, the second shutter of glasses, etc.).

[105] The interface unit 210 communicates with the display device 100. For example, the interface unit 210 may be used using a Bluetooth communication module to receive a synchronization signal and send information about the device 200 points by communicating with the device 100 display. The interface unit 210 may send a user command (or control command) inputted through the input unit 240 to the display device 100.

[106] As previously indicated, the synchronization signal may be received in the form of a transport stream in accordance with the Bluetooth communication standard and may include information about the opening or closing times of the block 250 of the first shutter of glasses and block 260 of the second shutter of the glasses of the device 200 points in synchronization with timing display content. The information included in the transport stream has been described as an example using the example of FIG. 4 and will not be explained further.

[107] The controller 220 controls the operations of the device 200 points. In particular, the controller 220 controls the eyewear shutter drive unit 230 by sending the synchronization signal received by the interface unit 210 to the eyewear shutter drive unit 230. That is, based on the synchronization signal, the controller 220 controls the eyeglass shutter drive unit 230 to generate a trigger signal for actuating the first eyeglass shutter unit 250 and the second eyeglass shutter unit 260.

[108] The eyeglass shutter drive unit 230 generates a trigger signal based on the synchronization signal received from the controller 220. In particular, based on the sync signal, the eyeglass shutter drive unit 230 can open at least one of the first shutter unit 250 and the second shutter unit 260 points in accordance with the timing of the display of one of the content options displayed by the display device 100.

[109] The first shutter block 250 and the second shutter block 260 open or close the shutter points in accordance with the trigger signal from the block 230 drive shutter glasses. For example, block 250 of the first shutter of glasses and block 260 of the second shutter of glasses open the shutter of the glasses at the same time when one of the content options is displayed, and close the shutter lenses when the second content that is not synchronized with the device of the glasses is displayed. Therefore, a user wearing the device 200 points can watch one content from a variety of displayed content options without viewing the second content.

[110] Additionally, when viewing 3D content using the glasses device, the first glasses shutter unit 250 and the second glasses shutter unit 260 can open and close the glasses in turn. That is, in accordance with the trigger signal, the first shutter unit 250 can open when the image for the left eye from 3D content is displayed, and the second 260 shutter unit can open when the image for the right eye from 3D content is displayed.

[111] The input unit 240 receives a user command for controlling the display device 100. In particular, the input unit 240 may receive a selection command to select one of the content representations. To accomplish this, the input unit 240 may include a button, a touch panel or a toggle button, etc. to select a presentation of the content. In case the user has entered a selection command to select one of the plurality of content representations into the input unit 240, the user can transmit information related to the selected content representation to the display device 100 and receive a synchronization signal corresponding to the selected content representation from the display device 100 . The input unit 240 may receive a response signal to confirm or reject a user command or a control command to control one of the content representations.

[112] Hereinafter, the operations of the display device 100 in accordance with predetermined events are illustrated by examples.

[113]

[114] An event of receiving a control command to control one of the content representations

[115] FIG. 7 is a diagram illustrating the effect of a control command received from the remote control device 300 on another representation of the content.

[116] When a plurality of viewers wears devices 200-1 and 200-2 points synchronized with different representations of the content, and one user watching the content enters a user command to control his / her presentation of the content, this user command may affect the user, watching content in a different presentation of the content. Since users watch their own content, they can sometimes control the display device 100 without notifying other users of the content. For example, when the content viewed through the device 200-1 points shows a dramatic series, and the film in the content viewed through the other device 200-2 points ends, as shown in FIG. 7, a user wearing another device 200-2 points can turn off the display device 100. In this case, the presentation of the content of the device 200-1 points is undesirable, and, accordingly, it is necessary to notify the other user of the entered control command and seek consistency in management, in accordance with the type of control command.

[117] According to an exemplary embodiment, for receiving a control command to control one of the content representations, the controller 140 may selectively display a message informing of the control command entered in the other content representation according to the type of the control command. As mentioned above, when a control command is input to the display device 100 from the glasses device 200-1 or 200-2 viewing one content view, this control command may affect another content presentation. However, the management team may not affect another presentation of the content, or the effect, if any, may be ignored. Therefore, when a control command is received from the remote control signal receiver 170, in accordance with the type of the control command, the controller 140 controls to provide notification of the control command entered by another presentation of the content, or performs a control operation when there is no need to provide a notification.

[118] The control team is divided into an executable operation and an operation with a restriction of execution based on the impact on another presentation of the content. When there is no impact on another presentation of the content, the control team is defined as an executable operation in any case. Conversely, when another presentation of the content is impacted, the execution may change in accordance with the consent or disagreement of another user or with other conditions. Therefore, a control command is defined as an operation with execution restriction.

[119] An executable operation indicates a control command when another representation of the content is not affected, as mentioned above. A control command for the operation to be performed may include a content change command to change the content of the selected content view, a volume control command to adjust the volume of the content audio signal, an on-screen menu (OSD) command to display the OSD menu in the selected content view, and an image quality control control command to adjust the quality of the image frame displayed in the selected content view.

[120] For example, when a volume control signal is input from one device 200 points and the volume control of the corresponding device 200 points is performed, another presentation of the content is not affected at all. Therefore, the volume control operation is among the operations performed. However, since a control command for controlling the output volume (overall volume) of the display device 100 may affect another presentation of the content, such a control command is a run restriction command. For example, with regard to the operation of changing the content, various content can be viewed through one presentation of the content. Therefore, changing the content of one content view does not affect other content views.

[121] An operation restricting execution refers to a control command in which another representation of the content is exposed. For example, the operation with the restriction of execution includes the operation of controlling the on-off power and the operation of controlling the output characteristic of the display device 100. That is, a user watching a single presentation of the content may turn off the display device 100. In this case, the user will no longer be able to watch another presentation of the content and, accordingly, the operation of turning the power on / off is among the operations with a limited execution. Further, the operation of controlling the output characteristic denotes a command for controlling the dependent parameters of the display device 100. For example, the brightness of the screen may be adjusted or the method of reception may change.

[122] FIG. 8 is a block diagram of a display device 100 in accordance with an exemplary embodiment.

[123] The device 100 of FIG. 8 recognizes an executable operation and an operation with a restriction of execution and may further include a memory unit 180 for storing information about a control operation divided into an executable operation and an operation with a restriction of execution.

[124] Having received the control command from the remote control signal receiver 170, the controller 140 can determine whether the received control command is an executable operation or a restriction execution operation by comparing the received control command with information about the control operation stored in the memory unit 180.

[125] When a control command relates to an executable operation, the controller 140 performs a control operation corresponding to a control command for presenting content. That is, for a control command related to controlling the volume of the content presentation, the controller 140 sends a volume control signal without providing a notification in the other content presentation. Conversely, when the control command refers to a run-limited command, the controller 140 controls the signal processor 120 and the display unit 130 to display a message notifying the control command entered in another representation of the content. For example, the signal processor 120 converts the message related to the control command into image data and combines this image data with an image frame of another content representation. The display unit 130 outputs the combined image frame to another content representation. For example, when a shutdown control signal is inputted through one content view, the message “Channel 1 user wants to turn off the display” may be displayed in another content view.

[126] At this time, a user watching a different presentation of the content may send a response signal to the display device 100 to agree or disagree with the control command. For example, the device 200 points can receive a signal for agreement or disagreement with the control command from the user through the input unit 240, and send the signal to the display device 100 using the interface unit 210. The user can send the signal through the remote control device 300 or directly input the signal through an input unit (not shown) of the display device 100. In the event that a signal is inputted through the input unit 240 of the device 200 points and a response signal expressing agreement with the control command is received from another device 200 points consistent with the other presentation of the content, the controller 140 performs a control operation corresponding to the control command. When a response signal disagreeing with the control command is received, the controller 140 does not perform a control operation corresponding to the control command. That is, when an input signal is received to turn off the display device 100, the controller 140 displays the message “Channel user 1 wants to turn off the display. Do you agree with this? ”In another presentation of the content. When a response signal expressing agreement with the control command is received from the interface unit 210 of another device 200 points, consistent with another representation of the content, the controller 140 turns off the display device 100.

[127] Meanwhile, if, after a predetermined period of time, the display device 100 does not receive a response signal, priority may be given to presenting the content from the entered control command, and the control operation corresponding to the control command may be performed. That is, in the absence of receiving a response signal to the control command from another device 200 points, consistent with a different presentation of the content for a predetermined period of time counted from the moment the message was displayed, the controller 140 may perform a control operation corresponding to the control command. However, priority can be given to another presentation of the content, taking into account the impact on another presentation of the content, and thus, the reception of the response signal of disagreement can be determined. In this case, no control operation corresponding to the control command is performed. When the control commands are differentiated and the response signal is not received, the control operation corresponding to the control command can be performed by determining the reception of the response signal of disagreement with a large influence on another presentation of the content, and determining the reception of the signal of consent with a small influence.

[128] In another aspect of the exemplary embodiment, the user of the first content presentation may be notified that the control command is affecting the second user of the second content presentation or a variety of other users watching a variety of other content presentations. The user of the first presentation of the content may then be questioned as to whether he wants to continue the implementation of the control command, and the user may confirm or reject the continuation of the execution of the control command. Additionally, in another aspect of the exemplary embodiment, the user of the first presentation of the content can only confirm the continuation of the control command if the device of glasses synchronized with the first presentation of content has priority over the device of glasses synchronized with the second presentation of content.

[129] Accordingly, the execution of the control operation may be different depending on the influence of the control command entered in one of the content representations on the other content representation. In particular, a more stable display with multiple representations can be achieved by notifying, in a different representation of the content, a large impact on another representation of the content and obtaining consent to perform.

[130]

[131] An event in which at least one of the content representations is not synchronized with the device points

[132] When it is detected that the content is not connected to the device 200 points, the controller 140 controls to add and display a message object that directs the connection of the device 200 points in a content representation not consistent with the device 200 points, which is explained below with with reference to FIG. 9.

[133] FIG. 9 is a diagram of a message object displayed to provide guidance for connecting a device 200 points, in accordance with an exemplary embodiment.

[134] The device 200-1 and 200-2 points communicate with the device 100 display, using their own identification information. When the glasses devices 200-1 and 200-2 are paired with the display device 100, the identification information of the glasses devices 200-1 and 200-2 is transmitted to the display device 100. According to an exemplary embodiment, the Bluetooth address of the interface unit 160, which is used to communicate with the glasses devices 200-1 and 200-2, can be used as information for identifying the glasses device. In accordance with the identification information received from the devices 200-1 and 200-2 points, or the Bluetooth address, the interface unit 160 of the display device 100 transmits any of the synchronization signals corresponding to the content views, the devices 200-1 and 200-2 points. In doing this, matching information between the content presentations and the glasses devices 200-1 and 200-2 may be generated or stored.

[135] Here, the interface unit 160 of the display device 100 may check the matching information reflecting the matching between the content and the glasses devices 200-1 and 200-2 under the control of the controller 140, and determine whether this content includes content that is not consistent with the devices 200 -1 and 200-2 points.

[136] Upon detection of content not synchronized with devices 200-1 and 200-2 points, the signal processor 120, from a variety of processors 120-1 - 120-n, can process a message object to process content not synchronized with the device 200 points which controls the connection of the device 200 points to the image frame of the corresponding content, and the display unit 130 may display the image frame of the added message object in turn with the image frame of other content.

[137] When a new glasses device 200 is connected, the controller 140 may control to automatically synchronize the new device 200 points with the presentation of content not synchronized with the device 200-1 and 200-2 points. When the corresponding presentation of the content is consistent with at least one device 200 points, according to the message object that directs the connection of the device 200 points, the controller 140 may control to make the message object displayed in the corresponding content representation disappear.

[138] With reference to FIG. 9, the display device 100 displays the second content, and the device 200-1 and 200-2 points are synchronized with the first presentation of the content and the third presentation of the content, respectively. When the second content is displayed, all the shutter points of the device 200-1 and 200-2 points are closed. Since in this case there are no glasses synchronized with the second presentation of the content, the display device 100 can add and display a Please Connect Glasses message object, which manages the connection for the second content presentation and the device 200 points.

[139] Meanwhile, viewers who wear the device 200-1 and 200-2 points and watch the first and third content, can not see the message object displayed in the second content, while the viewer looking at the display screen without the device glasses see a display screen consisting of superimposed content images, and see a message object added to the second content and superimposed on other content images. Thus, the viewer looking at the display screen without the device 200 points, can find out that part of the current representations of the content is displayed without synchronization with the device 200-1 and 200-2 points.

[140] Here, when the point device 200 is connected to the display device 100, the new point device 200 may automatically match a second presentation of content that is not consistent with the existing point devices 200-1 and 200-2.

[141] The message object that controls the connection of the device 200 points may not only be the message object of FIG. 9, but also any other object providing a notification that there is no matching of the corresponding content with the glasses 200. For example, the message object may include a message notifying that there is no agreement, such as “Glasses are not connected”, or a message providing details regarding connecting glasses.

[142] Thus, the user can intuitively understand that the specific content is not currently connected to the device 200 points without distracting the viewer watching the content in a multi-view mode, and the content not connected to the device 200 points can be matched with the new device points more simply.

[143]

[144] A multi-view mode launch command input event

[145] When the predetermined event is the input event of the multi-view mode launch command and when the multi-view mode start command is input, the controller 140 may control to display a message object asking whether to synchronize the corresponding content representation in the image frame of each content representation , and in order to consistently coordinate the content with the devices 200-1 and 200-2 points, as described below with reference to FIG. 10a and 10b.

[146] FIG. 10a and 10b depict a message object displayed to ask whether to synchronize with content, in accordance with an exemplary embodiment.

[147] When a user enters a multi-view mode launch command, the display device 100 alternately displays a plurality of content, initiating a multi-view mode. Here, the signal processors 120-1 to 120-n may add a message object asking whether to match the corresponding content in the image frame of each content, and the display unit 130 may alternately display the image frames of the added object.

[148] The interface unit 160 sequentially matches the presentation of content to the glasses 200-3, 200-4 and 200-5 connected to the display device 100. Here, one representation of the content is consistent with a predetermined time, and when a predetermined time passes, another representation of the content may be negotiated. This applies to a plurality of glasses devices 200-3, 200-4, and 200-5 connected to the display device 100.

[149] Meanwhile, when receiving a response to the message from the at least one device 200 points, the interface unit 160 may coordinate the presentation of the content displayed at the time of receiving the response with the device points, which sends the response. The response to the message means the input of the content selection command through the input unit of devices 200-3, 200-4 and 200-5 points or through a remote control device.

[150] With reference to FIG. 10a, the display device 100 alternately displays the first, second, and third content, and currently displays a picture frame of the first presentation of the content. The message object “Please click to view this image on the screen” is added to the image frame of each content. Meanwhile, all of the devices 200-3, 200-4 and 200-5 points are consistent with the first presentation of the content. When the selection command for selecting the first content that is currently already agreed upon is inputted through the input unit 240-3 of the left score device 200-3, the left score device 200-3 sends a selection command to the display device 100. Even when the predetermined time interval ends, the communication interface unit 160 of the display device 100 can save the matching of the left device 200-3 points and the first content.

[151] In FIG. 10b, the device 200-4 and 200-5 points are consistent with the second presentation of the content after the predetermined time interval of FIG. 10a. However, since the left glasses device 200-3 continues to continuously coordinate with the first presentation of the content by sending a selection command to the display device 100 in FIG. 10a, the viewer who wears the left device 200-3 points may continue to watch the first presentation of the content. Meanwhile, the message object requesting approval is not added to the image frame of the first presentation of the content agreed upon at a predetermined time. Therefore, the viewer selecting the first content can watch the first content without interrupting the object when a predetermined time passes.

[152] When the user enters a selection command through the input unit 240-4 of the device 200-4 points, consistent with the second content in FIG. 10b, the device 200-4 points sends a selection command to the display device 100, and the communication interface unit 160 of the display device 100 stores the matching of the device 200-4 points and the second content. Also, when the user enters a selection command through the input unit 240-5 of the device 200-5 points, consistent with the second content in FIG. 10b, the device 200-5 points sends a selection command to the display device 100, and the communication interface unit 160 of the display device 100 stores the matching of the device 200-5 points and the second content.

[153] Accordingly, the user can intuitively distinguish between the beginning of a mode with a plurality of views and entering a selection command to view specific content.

[154] The message object requesting approval from the corresponding content is not limited to the message object of FIG. 10a and FIG. 10b in one or more other exemplary embodiments. That is, in accordance with one or more exemplary embodiments, any object that leads to agreement with the corresponding content may be used. In addition, a timer showing the remaining time can be added and displayed in the image frame of the corresponding content so that the user can find out the remaining time for entering the selection command to select the content.

[155] An event in which a eyeglass device is connected

[156] In the event that the specific event is an event in which the eyeglass device is connected when the eyeglass device 200 is connected to the interface unit 160, the controller 140 may control to synchronize one of the plurality of content views and the eyeglass device.

[157] According to an exemplary embodiment, as illustrated in FIG. 9, the controller 140 may control such that a newly connected eyeglass device is synchronized with a content presentation from a plurality of content representations that is not synchronized with another eyeglass device. According to another aspect of an exemplary embodiment, in the case where the content representations can be differentiated as the main content representation and the at least one auxiliary content representation, the controller 140 may control such that synchronization is performed with the main content representation. The main presentation of the content may be the presentation of the content remaining even when a conversion has been made from a multi-view mode to a single-view mode. In accordance with another aspect of an exemplary embodiment, as illustrated in FIG. 10, the controller 140 can control so that when the glasses device is connected, it is synchronized with a plurality of content representations sequentially at a predetermined time interval, and when the content presentation select command is received from the glasses device, the controller 140 can control so that the glasses device is synchronized with the presentation of content synchronized with the device points at the moment when the selection command was received.

[158] An event in which the remote control device enters a command request right control

[159] When the predetermined event is an input event of a command request right control from the remote control device 300 and when the command request right control is entered, the controller 140 may control to add and display an image object indicating a control right in an image frame of one of a plurality content as described below with reference to FIG. 11a and 11b.

[160] FIG. 11aA and 11b depict an image object indicating a control right in accordance with an exemplary embodiment.

[161] When a control right request command is inputted from the remote control device 300, an image processor for processing content from a plurality of content representations displayed through an authorized content representation in the display device 100 may add an image object indicating a control right to the image frame of the corresponding content.

[162] The controller 140 may control to sequentially change content displaying an image object each time a control right request command is entered. That is, when an image object is added and displayed in the image frame of any one content, and the command request right control is again entered from the remote control device 300, the image object indicating the control right is added and displayed in the image frame of any other content. Each time a control right request command is entered, the content displaying the image object may be sequentially changed. Consequently, the viewer can intuitively and easily distinguish between the authorized presentation of the content.

[163] A control right request command denotes a user command that is entered by a user watching the content through any one of the content representations in order to control the corresponding content representation. A command request right control can be entered by pressing or touching a specific button on the remote control device 300, and a command entered to control the display device 100, for example, pressing a channel or volume control button, can be recognized as a command request right.

[164] With reference to FIG. 11a, a control right request is input from the user remote control device 300, and a star-shaped image object indicating the control right is added and displayed in the image frame of the second content. The viewer who wears the device 200-6 points, consistent with the second content, and watches the second content, can recognize the image object indicating the control right displayed on the display device 100 and control the second content using the remote control device 300. Here, managing the second content may correspond to controlling the volume that corresponds to the second content, setting the display environment of the second content, or another presentation of the content by switching to another channel if the second content is a broadcast program.

[165] Meanwhile, the viewer who wears the device 200-7 points, consistent with the third presentation of the content, can neither recognize the image object nor manage the third content.

[166] Here, when the user re-enters the command command request right control, a star-shaped image object indicating the control right is added and displayed in the image frame of the third content. In FIG. 11b, the display device 100 displays the third content with the added image object, and the viewer who wears the device 200-7 points can see the image object added to the third content. The viewer watching the second content can neither recognize the image object nor control the second presentation of the content.

[167] When the command for requesting control rights is re-entered, a star-shaped image object is added and displayed in the image frame of the first content, and it can be changed sequentially each time a command for requesting control rights is entered.

[168] An image object indicating a control right can be not only a star-shaped image object, but also any image or text reflecting a control right that the viewer can recognize. One or more exemplary embodiments is not limited to an object of the image, but can be applied to some object of the message, such as "control", indicating the right to control. When the command request for the right to control is not re-entered within a predetermined time, the controller 140 can make the image object disappear after a predetermined time.

[169] A command to request a control right can be entered not only by the remote control device 300, but also by the input unit 240 of the device 200 points in one or more other exemplary embodiments. In this case, the image object indicating the control right can be added and displayed in the content view corresponding to the device 200 points, where the command request control rights.

[170]

[171] Multiple View Mode Complete Command Input Event

[172] When a predetermined event is an event for entering a multi-view mode completion command, and when a multi-view mode completion command is inputted, the controller 140 may control to add and display a message object notifying the completion of the multi-view in image frames all content as described below with reference to FIG. 12.

[173] FIG. 12 depicts a message object notifying the completion of a plurality of representations in accordance with an exemplary embodiment.

[174] When the multi-presentation mode completion command is inputted by the remote control device 300, the display device 100 can add and display a message object notifying of the completion of the multi-presentation mode in the image frames of the entire displayed content, and end the multi-presentation mode.

[175] As shown in FIG. 12, when the multi-view mode completion command is inputted by the remote control device 300, the display device 100 adds and displays a message object notifying of the completion of the multi-view mode, such as “Exit the multi-view mode”, in image frames all of the first , second and third displayed content. Therefore, the viewer can intuitively understand that the multi-view mode is completed.

[176] A multi-presentation mode completion command can be entered not only by the remote control device 300, but also by the input unit 240 of the device 200 points in one or more other exemplary embodiments.

[177] When the multi-view mode is completed, only content displayed before the multi-view mode is displayed, and other content options are no longer displayed. However, it is understood that one or more exemplary embodiments is not limited to this. For example, in accordance with one or more exemplary embodiments, only content having a control right until the end of a multi-presentation mode can be displayed, and other content may not be displayed.

[178] Although the object is, but is not limited to, a message object or an image object in the above exemplary embodiments, various objects, such as an icon, logo, text label and symbol, can be represented in accordance with a predetermined event.

[179] Adding an object to an image frame in a signal processor 120 may be performed by an image processor video processor, and a frame frequency converter may add an object to an image frame with a converted frame frequency. Also, an additional data processor for processing subtitles can add an object. That is, when the content is generated as image frames, the object can be added at any phase before the content is displayed on the display unit.

[180] FIG. 13 is a block diagram of a remote control device 300 in accordance with an exemplary embodiment.

[181] With reference to FIG. 13, the remote control device 300 includes a detection unit 310 (e.g., a detector), an input unit 320, a control unit 330 (e.g., a controller), and an interface unit 340.

[182] The detection unit 310 receives signals from a plurality of points devices 200 corresponding to a plurality of content representations, detects a point device 200 closest to the remote control device 300, and sends the detected signal to the control unit 330 of the remote control device 300.

[183] More specifically, the detection unit 310 can determine the distances between the 200 point devices and the remote control device 300, and among the 200 point devices, detect the 200 point device closest to the remote control device 300.

[184] In this case, the detection unit 310 can detect the device 200 points using a detection method, such as radio frequency identification (RFID) or a magnetic sensor, which makes it possible to register small distances between the remote control device 300 and the device 200 points.

[185] Using the RFID as the detection method, the detection unit 310 can compare the reception intensity of the radio frequency (RF) signals received from the device 200 points, and determine the device 200 points, which transmits an RF signal having a maximum reception intensity, as the nearest device points .

[186] The device 200 points may further include a block 270 output signal (see Fig. 14). FIG. 14 is a block diagram of a glasses device 200 in accordance with an exemplary embodiment. The signal output unit 270 of the glasses device 200 may include an RFID tag or component corresponding to a method for determining the distance of the remote control device 300. In more detail, when the remote control device 300 registers the distance to each eyeglass device using an RFID, the signal output unit 270 may include an RFID tag.

[187] The input unit 320 of the remote control device 300 receives a user command. The input unit 320 may utilize various input interfaces, such as a keyboard, touchpad, scroll wheel, joystick, dial, etc., at least individually or in combination, to switch a channel or change the audio volume.

[188] When the user selection command is inputted by the input unit 320, the control unit 330 generates a control signal for controlling the presentation of the content corresponding to the nearest 200 points device found among the 200 points devices in accordance with the user selection command.

[189] The control signal may include at least one of the points device IDs, which is identification information about the nearest points device 200 or content presentation information corresponding to the nearest points device 200.

[190] To accomplish this, the remote control device 300 may receive information regarding the presentation of content corresponding to the glasses device from the glasses device. According to an exemplary embodiment, each eyeglass device may include information related to the presentation of content that may be included in the signal, an output signal for recording a distance, and the control unit 330 may generate a control signal using information related to the presentation of content nearest device points. According to another exemplary embodiment, the control unit 330 may request and receive information regarding the presentation of content from the nearest glasses device when the nearest glasses device is determined. Meanwhile, the glasses device 200 and the remote control device 300 can transmit / receive information regarding the presentation of content using the input unit 270 and the detection unit 310 for determining the distance, however, an interface unit (not shown) can further be configured to transmit / receive information in regarding the presentation of content.

[191] The control command may include, for example, any one of such commands as a content change command for changing content in a content presentation corresponding to the device 200 nearest to the remote control device 300, a volume control command for adjusting the volume of the content audio signal, a command displaying the OSD menu to display the OSD menu in the content view and an image quality adjustment control command for adjusting the quality of the image frame displayed in the view content, etc.

[192] The interface unit 340 sends a control signal generated by the control unit 330 to a remote control signal receiver 170 of the display device 100. The communication between the interface unit 340 and the remote control signal receiver 170 may involve a communication scheme such as Bluetooth, infrared and Zigbee, and various wireless communication schemes for transmitting and receiving signals over a communication channel, for example, a short-range communication channel.

[193] In the present exemplary embodiment, the user can selectively control the presentation of content corresponding to the nearest device 200 points by changing the location of the remote control device 300 without having to repeatedly enter a user command to selectively control one of the content representations. It is worth noting that the message or image object can be added and displayed in the content view, which can be controlled at the moment.

[194] FIG. 15 is a flowchart of a method for controlling a display device 100 in accordance with an exemplary embodiment. Redundant descriptions regarding the display device 100 will be omitted here.

[195] The display device 100 receives a plurality of content (operation S1510). More specifically, the display device 100 receives many different content options. Next, the display device 100 generates image frames (operation S1520). The display device 100 may generate image frames by processing the received content. The display device 100 alternately displays image frames (operation S1530). More specifically, the display device 100 generates a plurality of content representations and alternately displays frames of content images corresponding to the content representations.

[196] Here, when a predetermined event occurs (operation S1540-Y), the display device 100 performs an operation corresponding to this event (operation S1550). A predetermined event may include an event of receiving a control command to control one of the content representations from the remote control device 300, an event in which at least one of the content options is not synchronized with the device 200 points, an input event of a multi-mode launch command submissions, a command right request request command input event from the remote control device 300, a mode completion command input command event with a plurality of views, etc. If a predetermined event does not occur (operation S1540-N), the display device continues to alternately display image frames (operation S1530).

[197] An event of receiving a control command from the remote control device 300 to control one of the content representations is explained below with reference to FIG. 16 and 17.

[198] FIG. 16 is a flowchart of a method for controlling a display device 100 in accordance with an exemplary embodiment.

[199] With reference to FIG. 16, receivers 110 of the display device 100 receive a plurality of content (operation S1610), and signal processors 120 generate image frames by processing the content (operation S1620). The display unit 130 outputs a plurality of content representations by combining frames of the content image images (step S1630), and the synchronization signal generator 150 generates synchronization signals to synchronize the representations of the content and the device 200 points (step S1640). The interface unit 160 transmits synchronization signals to the device 200 points (operation S1650). When a control command is entered for any one presentation of content (operation S1660-Y), while a plurality of representations of content is output, the display device 100 determines whether the control command is an executable operation or an operation with a restriction of execution, and selectively displays a message notifying others presenting the content of the control command, if the control command is an operation with a restriction of execution, or controls the display device in accordance with the control command if control and is an executable operation (operation S1670).

[200] FIG. 17 is a flowchart of a method for controlling a display device 100 in accordance with an exemplary embodiment. With reference to FIG. 17, receivers 110 of the display device 100 receive a plurality of content (operation S1705), and signal processors 120 generate image frames by processing the content (operation S1710). The display unit 130 outputs a plurality of representations of the content by combining frames of the content images (step S1715), and the synchronization signal generator 150 generates synchronization signals to synchronize the representations of the content and the device 200 points (step S1720). The interface unit 160 transmits synchronization signals to the device 200 points (operation S1725). When a control command is entered for any one presentation of content (operation S1730-Y), while a plurality of representations of content is output, the display device 100 determines whether the control command is an executable operation. Having determined the executable operation (operation S1735-Y), the display device 100 performs the operation corresponding to the control command (operation S1737). Having determined the operation with a restriction of execution (operation S1735-Y), the display device 100 displays a message notifying of the input of a control command in another representation of the content (operation S1740). When the consent signal to the operation with the restriction of execution is received from the device 200 points, consistent with the other content presentation (operation S1745-Y), or when the consent signal is not received, and when no signals are received for a predetermined period of time (operation S1755- Y), the display device 100 performs an operation corresponding to a control command, similar to the case of an executable operation (operation S1737). Conversely, upon receiving the signal of disagreement (operation S1750-Y), the display device 100 does not perform the operation corresponding to the control command.

[201] Meanwhile, when the predetermined event is an event in which at least one of the content representations is not consistent with the device 200 points in FIG. 15 and content representations include a content representation not consistent with the device 200 points, the method adds and displays a message object that controls the connection of the device 200 points in the image frame of at least one presentation of content that is not consistent with the device 200 points.

[202] When the predetermined event is the input event of the multi-view mode launch command and the multiple-mode start command is input, the display device 100 adds and displays a message object asking whether to synchronize the corresponding content representation in the image frame of each content representation, and sequentially aligns content with devices 200 points. Upon receiving a response to the message from at least one device 200 points or from the device 300 remote control, the display device 100 can coordinate the content displayed when the response is received, and the device 200 points that sent the response.

[203] When the predetermined event is an input event of a command request right control from the remote control device 300 and a command request right control is entered, the display device 100 adds and displays an image object indicating a control right in the image frame of one of the content options. The content displaying the image object may be sequentially changed each time a command for requesting control rights is entered.

[204] When the predetermined event is the input event of the multi-view mode completion command and the multi-view mode completion command is input, the display device 100 adds and displays a message object notifying the completion of the multiple views in image frames of all content.

[205] FIG. 18 is a flowchart of a method for controlling a display device in accordance with another exemplary embodiment.

[206] A plurality of content is received (operation S1810). Next, an image frame is formed (operation S1820). More specifically, each of the accepted content options is processed to form image frames. In addition, image frames are combined and a plurality of content representations are output (operation S1830).

[207] In addition, when the eyeglass device is connected to the display device, a synchronization signal is generated that synchronizes one of the plurality of content representations with the eyeglass device (operation S1840). Here, the generation of the synchronization signal can generate a synchronization signal that synchronizes the device points with a presentation of content from a variety of representations of content that is not synchronized with any device points. Otherwise, in the case where the content presentation includes a main content presentation and at least one auxiliary content presentation, a synchronization signal can be generated that synchronizes the eyeglass device with the main content presentation. Otherwise, a synchronization signal may be generated that sequentially synchronizes the device points with multiple representations of the content.

[208] In addition, the generated synchronization signal is transmitted to the eyeglass device (operation S1850). In the case where a synchronization signal that sequentially synchronizes the glasses device with a plurality of content representations is transmitted when the content presentation selection command is received from the glasses device, the glasses device can continuously synchronize with the content presentation synchronized with the glasses device at the time of receiving the selection command. That is, the display device 100 can sequentially transmit a synchronization signal for a plurality of content representations, and when a selection command is received from the device 200 points, the display device 100 can continuously transmit a synchronization signal transmitted at the time of receiving the selection command to the device 200 points.

[209] FIG. 19 is a flowchart of a method for controlling a remote control device 300 in accordance with an exemplary embodiment.

[210] With reference to FIG. 19, the remote control device 300 receives the signals continuously generated by the points device 200 by the detection unit 310 (operation S1910), and calculates the distances between the remote control device 300 and the points device 200 by analyzing these signals (operation S1920).

[211] The control unit 330 receives the calculated values from the detection unit 310 and selects a point device 200 closest to the remote control device 300 (operation S1930). When a user command is inputted by the input unit 320 (operation S1940), the control unit 330 generates and transmits the control command to the display device 100 by the interface unit 340 (operation S1950).

[212] The display device 100 receives a control command by the remote control signal receiver 170, and the controller 140 of the display device 100 controls the presentation of content synchronized with the selected device 200 points by analyzing the received control command (step S1960).

[213] Essentially, when users who put on their eyeglass device 200 and simultaneously watch selected content representations by means of the display device 100 control their content representations, each user can easily control the content and sound of his / her content presentation by simply presenting the remote control device 300 control closer to your device 200 points than to other devices 200 points, and entering the intended control command, without the need for preliminary implementation of separate ny manipulations with the regime.

[214] Meanwhile, a program for implementing methods in accordance with various exemplary embodiments may be stored on different recording media.

[215] In particular, the code for implementing the methods may be stored on various non-volatile storage media such as flash memory, read-only memory (ROM), erasable programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM), hard disk, removable disk, memory card, USB memory and CD-ROM.

[216] A polarization method in accordance with another exemplary embodiment is described below with reference to FIG. twenty.

[217] FIG. 20 depicts a presentation of content using a glasses device 200 including a polarizing lens, in accordance with an exemplary embodiment.

[218] Although the system alternately outputs frames of content images and the shutters of glasses are used for viewing in accordance with the exemplary embodiments described above, it is understood that one or more other exemplary embodiments are not limited to this. For example, in accordance with another exemplary embodiment, a polarization system can be used to output and view content.

[219] In this case, the display device 100 may further include a polarization element 190. The polarization element 190 may include a liquid crystal layer (not shown) for polarizing the image. The display device 100 controls the liquid crystal layer in a horizontal line or a vertical line using excitation voltage of different levels, and polarizes the output image of the content in a specific direction. At the same time, polarized content images can be arranged and displayed alternately. For example, one content is polarized horizontally and displayed. Following it, other content is polarized vertically and displayed. This process is repeated. Users can watch corresponding images, that is, corresponding representations of the content, by means of a 200-3 glasses device including horizontal polarizing lenses, and a 200-4 glasses device including vertical polarizing lenses. For example, different areas of an image frame may contain image information of various content. In this case, the areas can be polarized and output in different directions, and users can watch various representations of the content with devices 200 points, including lenses corresponding to the directions of polarization.

[220] At this time, the glasses devices 200-11 and 200-12 used to watch the display device 100 may include polarizing lenses corresponding to the polarization direction of the content to be viewed. When the device 200 points transmits only polarized images, the user can only watch the content intended for him / her. Devices 200-11 and 200-12 points do not need separate synchronization with the display device 100, cost-effectiveness can be achieved, and fluctuations in synchronization can be reduced. In FIG. 20, when images of content polarized horizontally and vertically are alternately displayed, the device 200-11 and 200-12 points, including the corresponding polarizing lenses, view the presentation of the content.

[221] When the control command for presenting the content is processed by the polarized display device 100 and the points device 200, the control command for presenting the content is output as an image frame of the polarized content. For example, when a control command relates to an operation with a restriction of execution, a message notifying the input of a control command is polarized in the same manner as another frame of the content image, and is displayed together with another content presentation image. Further, a user wearing the device 200 points, consistent with a different presentation of the content, can enter a response to agree or disagree with the management team, so as to control the display device 100.

[222] Although the above exemplary embodiments relate to a display device 100 including a display unit 130, it is understood that other exemplary embodiments are not limited to this. For example, other exemplary embodiments may be applied to an image processing device, such as a television set-top box, a self-contained device, an audio / video receiver, an optical media player, a TV sensor, etc. In addition, it is understood that in exemplary embodiments, one or more of the units of the above devices 100, 200, 300 may include a processor or microprocessor executing a computer program stored on a computer-readable medium.

[223] Although several exemplary embodiments have been demonstrated and described, those skilled in the art will appreciate that changes can be made to these exemplary embodiments without departing from the principles and essence of the inventive concept, the scope of which is defined in the attached claims and its equivalents.
