DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention.

1 and 2 illustrate a system for providing a plurality of contents to a plurality of users according to an embodiment of the present invention. As shown in FIGS. 1 and 2, the system includes a display apparatus 100 and an eyeglass apparatus 200.

The display apparatus 100 alternately displays a plurality of contents, generates a synchronization signal for synchronizing the spectacles 200 corresponding to the respective contents, and transmits them to the spectacles 200. The glasses apparatus 200 opens both the left shutter glass and the right shutter glass when one content is displayed according to a synchronization signal. Accordingly, the viewer wearing the spectacles 200 may view one content.

Meanwhile, in an embodiment of the present disclosure, when the switching mode is started, the display apparatus 100 and the glasses apparatus 200 may sequentially switch the contents and provide the same to the user. See FIG. 1 and FIG. 2 for a more detailed description.

As shown in FIG. 1, the display apparatus 100 alternately displays contents 1 to 4 in image frame units. In addition, the glasses apparatus 200 opens the shutter glass in synchronization with the display timing of the contents 2 to provide the contents 2 to the user wearing the glasses apparatus 200.

Meanwhile, as shown in FIG. 2, when a switching command is input through an input button 210 provided in the spectacle apparatus 200 and the switching mode is started, the display apparatus 100 and the spectacle apparatus 200 perform a content switching operation. Do this. Accordingly, a user wearing the spectacles 200 may view content 3, content 4, and content 1 sequentially. Subsequently, when a selection command is input through the input button 210, the spectacle apparatus 200 turns on both the left shutter glass and the right shutter glass in synchronization with the content 1 viewed by the user at the time when the selection command is input. Accordingly, the user can select and view the content 1.

3 is a schematic diagram for illustrating a spectacle device according to an embodiment of the present invention.

Referring to FIG. 3, the spectacles 200 includes an input button 210.

The input button 210 may be disposed at a predetermined position of the spectacles 200. The input button 210 may be a mechanical or electronic button. In the case of a mechanical button, when the user presses the input button 210 at a predetermined pressure, the kinetic energy is converted into an electrical signal and transmitted to the controller. In the case of an electronic button, an electrical signal is generated by using an electrical or magnetic change generated when the user touches the input button 210, and is transmitted to the glasses controller (not shown).

When the input button 210 is selected (depressed) while the spectacle apparatus 200 is turned off, a power supply unit (not shown) turns on the spectacle apparatus 200 by supplying power to the spectacle apparatus 200. Let's do it.

The glasses controller (not shown) may further include a counting module (not shown) that counts the time when the input button 210 is selected.

The spectacles controller (not shown) controls the spectacle apparatus 200 to perform a normal operation, a pairing operation, or a content changing operation according to a control command input through an input button.

That is, the eyeglasses controller (not shown) performs a turn-on operation when the input button is selected in the turned-off state, and when the input button 210 is pressed while the eyeglasses 200 is turned on ( pushed), a period in which the input button 210 is pressed, a number of times pressed, or a combination thereof performs different control operations. The period in which the input button 210 is pressed compares the preset threshold time with the pressed time period, and when it is less than or equal to the first threshold time, exceeds the first threshold time and is less than or equal to the second threshold time, and exceeds the second threshold time. Different control operations are performed in correspondence with each case. Also, the number of times of pressing is counted by the number of times of pressing for a preset time, for example, 2 seconds to perform a control operation corresponding to the number of times of pressing. According to another embodiment, the spectacles controller (not shown) may be implemented to combine the time pressed and the number of times pressed to perform a control operation corresponding thereto.

Hereinafter, the operation of the glasses controller (not shown) will be described in more detail.

The normal operation is an operation in which the spectacle apparatus 200 exits the minimum power consumption mode and performs data communication with the display apparatus 100. That is, in the data communication between the spectacle apparatus 200 and the display apparatus 100, the display apparatus 100 transmits a synchronization signal, a video data signal, and an audio data signal to the spectacle apparatus 200. These signals are received and output a video data signal and an audio data signal in accordance with the synchronization signal.

In addition, the eyeglasses controller (not shown) may perform the input button 210 for a time equal to or less than a preset first threshold time (for example, 1 second) while the eyeglasses 200 are turned on. If selected, a content change command for changing the viewable content among the plurality of contents through the interface unit is transmitted to the display apparatus 100.

The content change operation means that the display apparatus 100 displays a plurality of contents (contents 1 to 4) as shown in FIG. 1 and changes the contents to any one of these contents (change of the content view). In another embodiment, it may mean that the content broadcast in one channel is changed to the content broadcast in another channel as the broadcast channel changes (change of channel).

The pairing operation is an operation of sharing information between the display apparatus 100 and the spectacles 200. That is, the spectacle apparatus 200 requests authentication, and the display apparatus 100 may exchange information by authenticating whether the spectacle apparatus is the correct apparatus using the ID of the spectacle apparatus 200 or the like.

The eyeglasses controller (not shown) is selected by the input button 210 for a time period exceeding a preset first threshold time and less than or equal to a second threshold time (eg, 3 seconds) while the glasses apparatus 200 is turned on. If so, the interface unit is controlled to perform a pairing operation with the display apparatus 100. Even when the user does not select the input button 210, pairing may be automatically performed at a predetermined time period. For example, the spectacle apparatus 200 may perform pairing with the display apparatus 100 at an interval of 30 minutes. Such automatic pairing execution time may be adjusted by the display apparatus 100.

The eyeglasses controller (not shown) performs a turn-off operation when the input button 210 is selected for more than a second threshold time while the eyeglasses 200 are turned on. In this case, the turn-off operation may be an operation termination mode in which the glasses device 200 stops the operation by cutting off the power supplied to the glasses device 200 or may be a minimum power consumption mode in which constant power is supplied without completely shutting off the power. have.

In the operation end mode, when the input button 210 is selected for more than a third threshold time (for example, 5 seconds), the power supplied to the spectacle apparatus 200 is cut off to terminate the operation of the spectacle apparatus 200. If it is. On the other hand, the minimum power consumption mode stops most operations of the spectacle device 200 when the input button 210 is selected for a time period greater than a second threshold time (eg, 3 seconds) or less than a third threshold time. This operation performs only a periodic pairing operation.

The operation end mode and the minimum power consumption mode are the same in that data is not exchanged between the spectacle device 200 and the display device 100, but the operation end mode is changed to the input button 210 again. This must be pressed for the conversion to take place.

On the other hand, the minimum power consumption mode may be switched back to the operation mode even when the input button 210 is pressed to switch back to the operation mode or when a signal for detecting human motion is received through the sensor unit.

The spectacles controller (not shown) performs the turn-off operation of the spectacles 200 if the spectacles 200 are not used for a predetermined time. That is, the eyeglasses control unit (not shown) may switch the power supply unit to switch the operation mode of the spectacle device 200 to the minimum power consumption mode when the synchronization signal (or voice signal) is not detected for more than a preset time (for example, 30 seconds). (Not shown) can be controlled. Alternatively, the glasses controller (not shown) may detect the movement of the glasses device 200 or detect the motion of the human body through a sensor unit (not shown). When the human body cannot detect the motion of the human body through the sensor unit, the eyeglasses 200 are switched to the minimum power consumption mode as if the synchronization signal (or voice signal) is not detected for 30 seconds or more.

Alternatively, when the eyeglass control unit (not shown) receives the single view mode operation signal from the display apparatus 100, the eyeglass control unit (not shown) controls the operation of the interface unit of the eyeglass apparatus 200 so as not to receive the synchronization signal so that the synchronization signal does not receive the synchronization signal for 30 seconds or more. As detected, the spectacle device 200 is switched to the minimum power consumption mode.

The spectacles 200 may further include a volume button for increasing or decreasing the volume of the audio data signal received from the display apparatus 100. The volume button may be implemented in the form of a wheel. The user may be implemented to increase the volume by turning the wheel in a particular direction, or to decrease the volume by turning it in the opposite direction.

Hereinafter, the display apparatus 100 and the spectacles 200 according to various embodiments of the present disclosure performing the above functions will be described in more detail.

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

Referring to FIG. 4, the display apparatus 100 includes a plurality of receivers 110-1, 110-2,..., 110-n, and a plurality of signal processors 120-1, 120-2,. n), an output unit 130, a synchronization signal generator 140, an interface unit 150, and a controller 160. The display device 100 of FIG. 3 may be implemented as various devices including a display unit such as a TV, a mobile phone, a PDA, a notebook PC, a monitor, a tablet PC, an e-book, an electronic picture frame, a kiosk, and the like.

The plurality of receivers 110-1, 110-2,..., 110-n receive different contents, respectively. In detail, each receiver 110-1, 110-2,..., 110-n stores contents from a broadcasting station transmitting broadcast program content using a broadcast network or a web server transmitting content files using the Internet. Receive. It is also possible to receive content from various recording medium playback apparatuses provided in the display apparatus 100 or connected to the display apparatus 100. [ The recording medium playback device refers to a device that plays back content stored in various types of recording media such as CD, DVD, hard disk, Blu-ray disk, memory card, USB memory,

In an embodiment of receiving content from a broadcasting station, the plurality of receivers 110-1, 110-2,..., 110-n may include a tuner (not shown), a demodulator (not shown), and an equalizer (not shown). It may be implemented in a form including a configuration such as. In contrast, in an embodiment of receiving content from a source such as a web server, the plurality of receivers 110-1, 110-2,..., 110-n may be implemented as a network interface card (not shown). . Alternatively, in the case of receiving the contents from the various recording medium reproducing apparatuses described above, the plurality of receiving units 110-1, 110-2,..., 110-n may include an interface unit (not shown) connected to the recording medium reproducing apparatus. May be implemented. As such, the plurality of receivers 110-1, 110-2,..., 110-n may be implemented in various forms according to embodiments.

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

The signal processing units 120-1, 120-2,..., 120-n process the contents received from the plurality of receivers 110-1, 110-2,..., 110-n, respectively. An image frame can be configured. See FIG. 5 for a more detailed description.

5 is a block diagram illustrating a detailed configuration of a signal processor according to an exemplary embodiment.

Referring to FIG. 5, the signal processor 1 120-1 may include a demultiplexer 1 121-1, an additional data processor 1 121-1, a video processor 1 123-1, and an audio processor 1 124-1. And frame rate converter 1 125-1. Although only one signal processor 1 120-1 is illustrated in FIG. 5, all other signal processors 120-2,..., 120-n may have the same or similar structure as that of FIG. 5.

The demultiplexer 1 121-1 allocates additional data, video data, and audio data included in each content to each processing unit when operating in the multi-view mode. That is, the video data, the audio data, and the additional data are separated from the content received by each of the receivers 110-1, 110-2, ..., 110-n, and the video data, audio data, and additional data are divided into the corresponding data processor, video processor, and audio processor. Can be separated.

The additional data processor 1 122-1 may process the additional data separated by the demultiplexer 1 to display through the output unit when the content includes additional information such as an EPG (Electronic Program Guide) and subtitles. Added captions and the like may be added to the corresponding video frame.

The video processor 1 123-1 performs signal processing on video data included in content received from the demultiplexer 1 121-1. In detail, the video processor 1 123-1 includes a decoder (not shown) that performs decoding on video data, and a scaler (not shown) that performs up or down scaling in accordance with the screen size of the output unit 130. can do.

In addition, the video processor 1 123-1 may convert the video data into a data format corresponding to the frame rate converter 1 125-1. Specifically, while the input video data is in a top-to-bottom format, the frame rate converter 1122-1 performs a frame in a side-by-side format. In the case of processing, the video processing unit 1 123-1 may convert the image frames of the respective content in a side-by-side format by connecting the image frames of each content in parallel in the horizontal direction.

The audio processor 1 124-1 performs signal processing on audio data included in content received from the demultiplexer 1 121-1. Specifically, the audio processor 1 124-1 includes a decoder (not shown) for decoding audio data, a modulator (not shown) for modulating each decoded audio data into different frequency signals, and each modulated audio. The apparatus may further include an output unit (not shown) for transmitting data to the spectacles.

Each audio data output from the output unit 130 is provided to the user through output means such as earphones provided in the spectacles 100. Since these configurations are not directly related to the present invention, a separate illustration is omitted.

The frame rate converter 1 125-1 converts the frame rate of the content provided from the video processor 1 123-1 to match the multi-content display rate by referring to the output rate of the display apparatus 100. In detail, when the display apparatus 100 operates at 60 Hz, the frame rate converter 1 125-1 may convert the frame rate of each content to n × 60 Hz.

The video output unit of the output unit 130 alternately arranges and displays image frames of respective contents configured in the plurality of signal processing units 120-1, 120-2,..., 120-n. Specifically, the output unit 130 multiplexes and displays the image frames of each content provided from the plurality of signal processing units 120-1, 120-2,. do. In some cases, the output unit 130 may perform up or down scaling of an image frame for each content in accordance with the screen size.

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

As described above, a mode of alternately arranging image frames of each content and displaying the same may be referred to as a multi view mode (or a dual view mode). When the display apparatus 100 operates in a normal mode (or a single view mode) displaying only one 2D content or 3D content, only one of the plurality of receivers 110-1, 110-2,..., 110-n is displayed. Can be activated to process content. When the user selects the multi-view mode while operating in the normal mode, the display apparatus 100 may activate the remaining receiver to process data in the above-described manner.

Meanwhile, the above-described content may be 2D content or 3D content. 3D content refers to content that allows a user to feel three-dimensional by using a multi-view image in which the same object is expressed from different perspectives.

When using a plurality of 3D content, the output unit 130 is the left eye image and the right eye included in each of the 3D content provided by the plurality of frame rate converter (125-1, 125-2, ..., 125-n) Images may be multiplexed in a predetermined arrangement and alternately arranged with image frames of other contents.

Accordingly, the left eye image, the right eye image of the first content, the left eye image of the second content, the right eye image, the left eye image of the n-th content, and the right eye image are sequentially arranged and displayed, and the user displays the eyeglasses 200. Through this, the left eye image and the right eye image of one content are recognized.

The synchronization signal generation unit 140 generates a synchronization signal for synchronizing the glasses apparatus 200 corresponding to each content according to the display timing of each content. That is, the synchronization signal generator 140 generates a synchronization signal for synchronizing the spectacle apparatus 200 with the display timing of the image frame for the content in the multi-view mode.

The interface unit 150 transmits a synchronization signal to the spectacles 200. In this case, the interface unit 150 may transmit the synchronization signal to the spectacles device in various ways.

For example, the interface unit 150 may be provided with a Bluetooth communication module to communicate with the glasses device 200, and generate a transmission packet according to a Bluetooth communication standard to include a synchronization signal and transmit the generated packet to the glasses device 200. have.

That is, the transport packet includes time information for turning on / off the shutter glass of the spectacles 200 in synchronization with the display timing of each content. In detail, the transmission packet may include an offset time for turning on the left eye shutter glass of the spectacle apparatus 200, an offset time for turning off the left eye shutter glass, an offset time for turning on the right eye shutter glass, and a right eye from a reference time point set for each content. It may include information on the offset time to turn off the shutter glass. Here, the reference time point is a time point at which the vertical sync signal is generated in the image frame of each content, and time information on the time point at which the vertical sync signal is generated may also be included in the transport packet.

In order to perform communication according to the Bluetooth communication method, the interface unit 150 performs pairing with each eyeglass device. When pairing is complete, information about each eyeglass device 200, for example, a device ID, may be registered in the first interface unit 150. The interface unit 150 matches the display timing of each content with the information on the glasses 200 and generates one transport packet according to the Bluetooth communication standard. For example, the interface unit 150 may match information about different glasses devices for each content in the order in which the image frames of the content are arranged. That is, when two contents are provided in the multi-view mode, the image frames of the first, third, ..., n-th placed images match information about the first spectacle device, and the second and fourth The image frame of the content arranged at the n + 1 th position may match information about the second spectacle device (where n is odd). The eyeglass unit 200 can confirm the display timing corresponding to the own eyeglass unit information when the synchronization signal is received, and can turn the shutter glass on or off according to the confirmed display timing.

Although the above-described embodiment has been described as the interface unit 150 and the eyeglasses 200 performing communication according to the Bluetooth communication method, this is only an example. That is, in addition to the Bluetooth method, it is possible to use a communication method such as infrared communication, Zigbee, etc., and to perform communication according to various wireless communication methods capable of transmitting and receiving signals by forming a communication channel in other local areas. .

Meanwhile, the interface unit 150 may provide an infrared red (I / R) synchronization signal having a different frequency to the spectacle device 200. In this case, the spectacle apparatus 200 may receive a synchronization signal having a specific frequency and turn on or off the shutter glass according to the display timing of the corresponding content.

In this case, the interface unit 150 converts the infrared signal, which is repeatedly alternated between a high level for a first period and a low level for a second period at a predetermined time interval based on the synchronization information, To the device (200). The spectacle device 200 may be implemented to turn on the shutter glass during the first period of high level and turn off the shutter glass during the second period of low level. In addition, the synchronization signal may be generated in various ways.

The controller 160 controls operations of the first half of the display apparatus 100. Specifically, the controller 160 includes a plurality of receivers 110-1, 110-2,..., 110-n, and a plurality of signal processors 120-1, 120-2,. Each control unit may be configured to control the output unit 130, the synchronization signal generator 140, and the interface unit 150 to perform a corresponding operation. On the other hand, since the operation performed by each configuration of the display apparatus 100 has been described above, duplicate description thereof will be omitted.

6 is a block diagram illustrating a configuration of an eyeglass device according to an exemplary embodiment. In particular, the spectacles 200 of FIG. 6 interlock with a display apparatus 100 of FIG. 2 that alternately displays a plurality of contents in units of image frames, and includes an input button 210, a glasses controller 220, and a shutter glass. The driving unit 230 includes a first shutter glass unit 240, a second shutter glass unit 250, an interface unit 260, and a sensor unit 270.

The input button 210 may be implemented as one button. When the input button 210 is pressed while the spectacle apparatus 200 is turned off, power supply is started by a power supply unit (not shown) to operate the spectacle apparatus 200. The input button 210 generates an electrical signal for a selected time selected by the user and transmits the electrical signal to the controller 220.

Alternatively, when the input button 210 is selected by the user, the controller 220 generates a trigger signal to start counting the button selection time, and when the selection is finished, ends the counting to count the button selection time by the user. It works.

According to the present invention, the control unit 220 may be implemented to generate a corresponding control signal according to the number of times of selecting the input button 210 repeatedly within a predetermined time as well as the selection time of the user selecting the input button 210. have. For example, when the input button 230 is selected by the user once for less than one second while the eyeglass device 200 is turned on, the input button 210 directly outputs an electrical signal meeting the selection condition. Or trigger the control unit 220 to perform a corresponding control operation.

As another embodiment, the operation of the spectacle device 200 may be controlled according to the counted time by counting a time from the first time point at which the input button 210 is selected to the time point at which the selection button 210 is input again. will be.

The input button 210 receives a power on / off command, a pairing command, a content change command, or the like of the spectacles 200. To this end, the input button 210 may be implemented as a touch sensor, a mechanical button, or an electronic button. The input button 210 may be implemented to emit light in different colors according to the type of command input to the spectacles 200.

The controller 220 controls the operation of the first half of the spectacles 200. In particular, the controller 220 transmits a synchronization signal received through the interface unit 260 to the shutter glass driver 230 to control the operation of the shutter glass driver 230. That is, the controller 220 controls the shutter glass driver 230 to generate driving signals for driving the first shutter glass unit 240 and the second shutter glass unit 250 based on the synchronization signal.

 The controller 220 generates a control command signal corresponding to the selection time or the number of selections selected through the input button 210, and controls the shutter glass driver 230 or the interface unit 260 according to the control command signal. can do. In addition, the controller 220 may select a button selection time, a number of button selections, or a time from a first button selection time point to a second button selection time point selected through the input button 210 according to the on / off state of the spectacle apparatus 200. The power supply unit (not shown) may be controlled by differently recognizing the control unit, the interface unit 260 may be controlled, and the shutter glass driver 230 may be controlled.

When the input button 230 is selected while the power supply of the eyeglasses 200 is turned off, the control unit 220 receives an operation start signal so that the eyeglasses 200 may be driven by receiving power from a power source (not shown). Create

When the input button 230 is selected for a time of 1 second or less while the eyeglass apparatus 200 is turned on, the controller 220 generates a content change command and transmits it to the interface unit 260. The interface unit 260 transmits a content change command to the display apparatus 100. The display apparatus 100 generates a new synchronization signal corresponding to the content change command and transmits the new synchronization signal to the eyeglass apparatus 200, and the eyeglass apparatus 200 can watch the changed content according to the new synchronization signal. Since the content change has been described in detail above, a detailed description thereof will be omitted.

With the power supply of the spectacle device 200 turned on, the input button 210 exceeds the first input time (for example, 1 second) and for a time less than or equal to the second input time (for example, 3 seconds). When selected, the controller 220 pairs the glasses device 100 with the display device 100 and other peripheral devices connected to the display device 100.

When the input button 210 is selected for a time exceeding 3 seconds while the power of the spectacle apparatus 200 is turned on, the controller 220 cuts off the power supplied to the spectacle apparatus 100 and the spectacle apparatus 200 Turn off). In this case, when the input button 210 is selected for a third input time (for example, 5 seconds) or more, the controller 220 completely shuts off the power of the spectacles 200 to terminate the operation of the spectacles 200. do.

The shutter glass driver 230 generates a driving signal based on the synchronization signal received from the controller 220. In particular, the shutter glass driver 230 may include the first shutter glass unit 240 and the second shutter glass unit based on a display timing of one of a plurality of contents displayed on the display apparatus 100 based on the synchronization signal. 250) can be opened.

The first shutter glass unit 240 and the second shutter glass unit 250 turn on or off the shutter glass according to a driving signal received from the shutter glass driver 230. Specifically, the first shutter glass unit 240 and the second shutter glass unit 250 simultaneously open the shutter glass when one of the plurality of contents is displayed, and open all of the shutter glasses when the other contents are displayed. Let's do it. Accordingly, a user wearing the spectacles 200 may view one content.

In the case of 3D content, the first shutter glass unit 240 and the second shutter glass unit 250 may alternately open and close the respective glasses. That is, the first shutter glass unit 240 may be opened at the timing when the left eye image constituting one 3D content is displayed according to the driving signal, and the second shutter glass unit 250 may be opened at the timing when the right eye image is displayed. Can be.

When the switching mode is started, the control unit 220 controls the shutter glass driver 230 to sequentially change the opening timing of the first shutter glass unit 240 and the second shutter glass unit 250, among the plurality of contents. The viewable content is sequentially switched. That is, the controller 220 may check the display timing of each content by using the synchronization signal and control the shutter glass driver 230 to sequentially generate the driving signal based on the synchronization signal corresponding to each content. . Accordingly, the first shutter glass unit 240 and the second shutter glass unit 250 are opened every time an image frame of each content is displayed, and the user can sequentially view all the contents.

The interface unit 260 receives a synchronization signal from the display device.

For example, when the interface unit 260 is implemented as a Bluetooth communication module, the interface unit 260 may communicate with the display apparatus 100 according to a Bluetooth communication standard to receive a transport packet including a synchronization signal. In this case, the transport packet includes time information for turning on or off the first shutter glass unit 240 and the second shutter glass unit 250 of the spectacles 200 in synchronization with the display timing of each content. The apparatus 200 may turn on or off the shutter glasses according to the display timing corresponding to the glasses device.

On the other hand, the interface unit 260 may be implemented as an IR receiving module to receive the synchronization signal of the infrared form having a specific frequency. In this case, time information for turning on or off the first shutter glass unit 240 and the second shutter glass unit 250 of the spectacles 200 to be synchronized with the display timing of one of the plurality of contents is included. do. In addition, when the switching mode is started, the interface unit 260 may sequentially receive IR synchronization signals having different frequencies, and when the switching mode ends, the interface unit 260 may receive the IR synchronization signals that were received at the end time.

Meanwhile, the interface unit 260 may receive information about an image frame rate and an image frame period for each content from the display apparatus 100.

According to one embodiment of the present invention as described above, when the switching mode is started, the spectacle apparatus 200 changes the on / off time of the shutter glass to be synchronized with the display timing of each content, and turns on the shutter glass according to a selection command. Synchronizes the on / off time with the display timing of the specific content.

According to another embodiment of the present disclosure, the content switching operation may be controlled by the display apparatus. Hereinafter, an operation according to another exemplary embodiment of the present disclosure will be described in detail with reference to the display apparatus 100 and the eyeglass apparatus 200 illustrated in FIGS. 3 to 5. However, for the convenience of description, descriptions duplicated with FIGS. 4 to 6 will be omitted, and only the distinctive features in the present embodiment will be described.

The interface unit 150 provided in the display apparatus 100 communicates with the spectacles 200. For example, the interface unit 150 may include a Bluetooth communication module to perform wireless communication with the spectacles 200. However, in addition to the Bluetooth method, a communication method such as infrared communication or Zigbee may be used, and communication may be performed according to various wireless communication methods that may transmit and receive signals by forming a communication channel in other local areas. .

When the content change command is received from the glasses apparatus 200, the controller 160 of the display apparatus 100 performs a switching operation of sequentially switching the contents corresponding to the glasses apparatus 200 to other contents among the plurality of contents. . As such, the switching operation can be performed in various ways.

In detail, when a content change command is received, the controller 160 controls the output unit 130 to change the arrangement pattern of the image frames of the respective contents, and then enters the image frame position of the content corresponding to the spectacles 200. The image frame of the content may be located.

For example, it is assumed that the output unit 130 alternately arranges and displays the video frames of the first to third contents. When the content change command is received from the glasses device synchronized to the first content, the controller 140 sequentially outputs the image frame of the second content and the image frame of the third content at the image frame position of the first content. 130 can be controlled. Accordingly, the user wearing the spectacle device can switch and watch all contents in sequence.

Meanwhile, the controller 160 may control the synchronization signal generator 140 to change the synchronization signal when a content change command is received, and may process the glasses device to be synchronized with other contents among the plurality of contents.

For example, when the interface unit 150 is implemented as a Bluetooth communication module, the controller 160 sequentially matches information about the spectacle apparatus that has transmitted the content change command signal to the display timing of each content, thereby providing Each content can be synchronized sequentially. When the glasses device receives the synchronization signal, the glasses are turned on or off according to the display timing corresponding to the glasses device information, so that the user can view all contents sequentially.

If the selection command is received through the interface unit 150 while the content corresponding to the spectacle apparatus 200 is sequentially switched to other content among the plurality of contents, the controller 160 displays the content at the time when the selection command is received. The switching operation ends so that the device can view through the device.

In detail, when the selection command is input from the spectacle device while changing the arrangement pattern of the content or the synchronization signal, the controller 160 sequentially changes the content synchronized to the spectacle device. The spectacles may be synchronized based on the arrangement pattern of the content or the synchronization signal.

That is, the controller 160 ends the change of the arrangement pattern of the content at the time when the selection command is input and sequentially displays the plurality of contents according to the arrangement pattern of the rearranged content at the end time. Alternatively, the controller 160 may match the glasses device information to the display timing of the content displayed at the time when the selection command is input, and synchronize the glasses device with the content displayed at the time when the selection command is input. Accordingly, the user can watch the desired content according to the selection command.

On the other hand, the switching operation may be performed while the switching command is received from the spectacle apparatus. That is, the controller 160 may perform the content switching operation at the time when the switching command is received, and then control to stop the content switching operation when the reception of the switching command is terminated.

The interface unit 210 included in the spectacles 200 may communicate with the display apparatus 100. As described above, the interface unit 210 of the spectacle device 200 may be provided with a Bluetooth communication module to perform wireless communication with the spectacle device, and may use a communication method such as infrared communication or Zigbee in addition to the Bluetooth method.

The glasses controller 220 may change the content by transmitting a content change command to the display device to sequentially switch viewable content among the plurality of contents.

That is, the glasses controller 220 may transmit a content change command to the glasses device to control the operation of the display device to change the arrangement pattern of the image frame of each content or change the synchronization signal in the display device. The glasses controller 220 may transmit a selection command to the glasses device to control the operation of the display device such that the arrangement pattern or the synchronization signal of the content is fixed when the selection command is input. On the other hand, since the operation of the display device has been described above, duplicate description thereof will be omitted.

Meanwhile, the switching command and the selection command may be input from the user through the input button 210 provided in the spectacles.

For example, the display device may include one button implemented as a touch sensor or an operation button included in the input button 210, and the glasses controller 220 may display a command according to a selection time at which the input button 210 is touched. And the interface unit 260 and the shutter glass driver 230 may be controlled according to a corresponding command. However, this is only an example and may be implemented by dividing the content change command into a switching command and a selection command, respectively, or may implement a separate button operation for receiving each input.

According to another exemplary embodiment of the present disclosure, when the input button 230 is selected as the predetermined selection time, the display apparatus 100 may determine the image frame according to the selection command corresponding to the selection time of the input button 210. The spectacle device may be controlled to be sequentially synchronized with each content by changing the arrangement pattern or the synchronization signal, and the spectacle device may be synchronized with the display timing of the specific content according to the selection command. In addition, the power may be turned on / off according to the power state of the spectacles 200. In addition, the pairing operation may be performed according to the power state of the spectacles 200.

7 is a flowchart illustrating a method of driving a spectacle device according to an embodiment of the present invention.

Referring to FIG. 7, a method of driving a spectacle device according to an embodiment of the present invention includes performing a turn-on operation of the spectacle device (S610), counting a time when an input button is selected (S620), and In step S630, a control operation corresponding to the selection time is performed.

In operation S610, when the glasses apparatus 200 is powered off, when the input button 230 is pressed, the glasses apparatus 200 performs a turn-on operation. do. The turn-on operation is started by supplying the power of the power supply unit to the spectacles control unit of the spectacles 200.

In step S620 of counting the time when the input button is selected, when the input button is selected while the eyeglass apparatus 200 is turned on, the time at which the input button is selected and when the input button is not selected is counted. Detecting when the input button is selected is detected by detecting the electrical change generated by pressing the input button, and by detecting the electrical change generated by not pressing the input button. When the input button is pressed, the controller may be implemented to generate a current having a predetermined magnitude.

8 is a flowchart illustrating a control operation using the spectacle device according to an embodiment of the present invention in detail.

Referring to FIG. 8, the control operation using the spectacle device may include a button input step (S810), a button selection time counting step (S820), a button selection time and a first threshold time comparison step (S830), a content change step (S831), Comparing the button selection time and the second threshold time (S840), performing the pairing step (S841) and the step of turning off the glasses device power (S850).

In the button input step (S810), the user manipulates the input button 230 provided in the spectacles 200. The user touches or presses the input button 230 for a predetermined time to perform a button operation corresponding to a desired control command. At this time, the button input is a button input from the time when the input button 230 is pressed by the user until the end of the pressing operation.

The button selection time counting step (S820) counts the time from the time when the input button 230 is selected by the user to the time when the selection is finished. Since a method of counting a predetermined time is similar to that performed by a general counter, a detailed description thereof will be omitted.

In the step S830 comparing the button selection time with the first threshold time, the result of counting the button selection time selected by the user is compared with the first threshold time. In this case, the first threshold time may be preset to a default value of 1 second. This default value may be changed by the user.

If the button selection time selected by the user is smaller than the first threshold time (S830-N), the content currently being viewed is changed (S831). At this time, the step of changing the content (S831) is the other content (for example, cable broadcasting station) that the display device 100 is currently displaying the specific content (for example, content received from the Internet broadcasting station) that the user is currently watching Change the content to (received from). If the button selection time selected by the user is greater than the first threshold time (S830-Y), the button selection time is compared with the second threshold time (S840).

The button selection time and the second threshold time comparison step (S840) may be compared with the second threshold time when the button selection time selected by the user is greater than the first threshold time. In this case, the second threshold time may be preset to a default value of 3 seconds. This default value can be changed by the user.

When the button selection time selected by the user is smaller than the second threshold time (S840-N), pairing of the current spectacle apparatus 200 is performed again (S841). In this case, the pairing operation performing step S841 may interface data while sharing information between the eyeglasses 200 and the display apparatus 100 through a wireless transceiver. That is, when the spectacle apparatus 200 is an RF method, the ID of the spectacle apparatus is transmitted to the display apparatus 100, and the display apparatus 100 authenticates the spectacle apparatus based on the ID information received from the spectacle apparatus. Pairing is performed between the spectacle apparatus 200 and the display apparatus 100 by transmitting the connection permission information for allowing the connection to the spectacle apparatus to the spectacle apparatus. If the button selection time selected by the user is greater than the second threshold time (S840-Y), the power supply of the spectacle apparatus 200 is turned off (S850).

The power turn-off step (S850), by controlling the operation of the power supply unit for supplying power to the spectacle apparatus 200 to cut off the power supply to the spectacle apparatus 200 to turn off the driving of the spectacle apparatus 200. Alternatively, a part of the power is cut off to supply only the minimum power to the spectacles 200 so that the spectacles 200 operates in the minimum power consumption mode.

9A and 9B are schematic diagrams illustrating a configuration of a system for providing a plurality of contents according to another embodiment of the present invention. 9A and 9B are similar to FIGS. 1 and 2, but illustrate a concept of a content view and a content providing system in the case of 2D and 3D content.

As shown in FIGS. 9A and 9B, the present content providing system includes a display apparatus 1100 and a plurality of glasses apparatuses 1 and 2 1200-1 and 1200-2. 9A and 9B, for convenience, the glasses device 1200 is represented as two, but the number of the glasses device 1200 is theoretically unlimited and may be one or more.

9A is a diagram for describing a system for providing a plurality of 2D contents according to an exemplary embodiment.

The display apparatus 1100 alternately displays a plurality of 2D contents (contents A and B) in the plurality of content views (content views 1 and 2), and the glasses apparatuses 1 and 2 1200-1 corresponding to the respective content views. , And generates a synchronization signal for synchronizing the 1200-2, and transmits it to the eyeglasses 1200-1 and 1200-2.

In this case, the spectacle device 1 1200-1 opens both the left shutter glass and the right shutter glass when one content A is displayed according to the synchronization signal, and the left shutter when the other content B is displayed. It may be operable to turn off both the glass and the right shutter glass. Accordingly, the viewer 1 wearing the spectacles 1 1200-1 is placed in the content view A synchronized with the spectacles 1 1200-1 among the plurality of contents A and B that are alternately displayed. Only one piece of content A is displayed. In the same manner, viewer 2 wearing the eyeglass device 2 1200-2 may watch only the content B. FIG.

FIG. 9B is a diagram for describing a system for providing a plurality of 3D contents according to an exemplary embodiment.

As illustrated, when the plurality of 3D contents (contents A and B) are 3D contents, the display apparatus 1100 alternately displays the plurality of 3D contents (contents A and B), and displays a left eye image of each 3D content and The right eye image can also be displayed alternately.

For example, the left eye image and the right eye images AL and AR of the 3D content A may be displayed, and the left eye image and the right eye images BL and BR of the 3D content B may be alternately displayed. In this case, the eyeglass device 1 1200-1 synchronized with the content view 1 opens the left and right eye glasses at the display time point of the left eye image and the right eye image AL and AR of the 3D content A, and is synchronized with the content view 2. The spectacle apparatus 2 1200-2 may open the left and right eye glasses at the display time point of the left eye image and the right eye images BL and BR of the 3D content B. FIG.

Accordingly, viewer 1 wearing the spectacle device 1 200-1 views only the 3D content A, and viewer 2 wearing the spectacle device 2 200-2 only views the 3D content B. You will watch.

Here, the content view means a set of image frames for one content that can be viewed by a viewer wearing a spectacles when the image frames of each content are alternately arranged and displayed. However, the content view is a different concept from each content. For example, when the viewer 1 watches the content C by wearing the glasses device 200-1 synchronized with the content view 1 and changing the TV channel or playing another DVD content or the like while watching the content A, The content changes from A to C, but content view 1 does not change. That is, the concept of a kind of channel that can watch the content as the concept of the content.

Meanwhile, the display device 1100 and the glasses device 1200 may include Wi-Fi, Bluetooth, Infrared Data Association (IRDA), Radio Frequency (RF), IEEE 802.11, WLAN, HR WPAN, UWB, LR WPAN, It can communicate with various wireless communication technologies such as IEEE 1394.

10 is a block diagram illustrating a configuration of a display apparatus according to another embodiment of the present invention. Since the configuration of the display apparatus has been described with reference to FIG. 4, the following description will focus on differences, and overlapping portions will be briefly described.

According to FIG. 10, the display apparatus 1100 includes a plurality of receivers 1110-1, 1110-2,..., 110-n, a signal processor 1120, a display 1130, and a synchronization signal generator 1140. ), An interface unit 1150, and a controller 1160.

The plurality of receivers 1110-1, 1110-2,..., 1110-n respectively receive a plurality of contents.

The signal processor 1120 processes the contents received from the plurality of receivers 1110-1, 1110-2,..., 1110-n to form an image frame. The signal processor 1120 will be described in more detail with reference to FIG. 11.

FIG. 11 is a block diagram illustrating a detailed configuration of a signal processor according to another exemplary embodiment.

As illustrated in FIG. 11, the signal processor 1120 includes a video processor 1121, a sub frame generator 1122, and a frame rate converter 1123.

The video processor 1121 configures an image frame by performing signal processing on video data included in each content received from the plurality of receivers 1110-1, 1110-2,..., 1110-n.

The subframe generation unit 1122 generates a subframe for limiting viewing of each image frame. That is, the subframe generator 1122 may receive an image frame of each content from the video processor 1121 and generate a subframe corresponding to each image frame.

When the subframe is continuously displayed with the image frame, the subframe may be a frame generated in combination with the image frame to recognize the image frame as white noise. Alternatively, it may be a complementary color frame corresponding to the image frame. When the subframe is a complementary color frame corresponding to the image frame, the subframe may be recognized as a white frame if it is continuously displayed.

Accordingly, even if the viewer with limited viewing authority does not wear the spectacle device, the viewer cannot view the content with restricted viewing.

The frame rate converter 1123 converts the frame rate of each content provided from the video processor 1121 and the subframe generator 1122 according to the output rate of the display apparatus 1100.

The display unit 1130 displays a plurality of content views by combining the image frame and the sub frame of the content output from the signal processor 1120. The display unit 1130 corresponds to a video output unit among the elements of the output unit 130 of FIG. 4. In detail, the display 1130 multiplexes the image frames and the sub-frames of each content provided from the signal processor 1120 so that at least one of them is alternately displayed to display a plurality of content views. In some cases, the display 1130 may perform up or down scaling of an image frame for each content in accordance with the screen size.

The user wears the spectacle device 1200 that is linked to the timing at which the content view is displayed on the display unit 1130, and watches the desired content.

When using a plurality of 3D contents, the subframe generation unit 122 generates subframes for the left eye image and the right eye image, respectively, and the display unit 1130 provides each 3D content provided by the frame rate converter 1123. The left eye image, the right eye image, and the respective subframes included in the multiplexed display may be displayed in a predetermined arrangement form, and the user may recognize the left eye image and the right eye image of one content through the spectacle device 1200.

The synchronization signal generator 1140 generates a synchronization signal for synchronizing the spectacle device corresponding to each content view according to the display timing of each content view. On the other hand, the content view does not include a subframe generated by the subframe generator 1122, and therefore, the synchronization signal generator 1140 may adjust the eyeglasses according to the timing at which the image frame except for the subframe of each content is displayed. A synchronization signal may be generated to synchronize.

The interface unit 1150 is connected to the glasses device to communicate. In more detail, the interface unit 1150 may be connected to the glasses device according to a preset communication standard to perform communication.

The controller 1160 controls the operation of the first half of the display apparatus 1100. In detail, the controller 1140 may include a plurality of receivers 1110-1, 1110-2,..., 1110-n, a signal processor 1120, a display 1130, a synchronization signal generator 1140, and an interface. Each unit 1150 may be controlled to perform a corresponding operation.

In addition, the controller 1160 restricts viewing of the content according to whether the viewing authority of the content displayed on the content view mapped with the spectacles device 1200 is present. That is, the glasses apparatus 1200 mapped to the content view may determine whether the right to view the corresponding content may be restricted, and if the right to view the content does not exist, viewing of the content may be restricted. This will be described in detail with reference to FIG. 12.

12 is a diagram for explaining a synchronization signal for restricting viewing of content.

The video frames of the contents A and B and their subframes are alternately displayed on the display device. On the other hand, the spectacle device is mapped to the content view 1, and the content A is displayed in the content view 1. In addition, content B is displayed in content view 2. FIG.

If the spectacle apparatus has the authority to view the content, the interface unit 150 is controlled to transmit the synchronization signal 1 for turning on the spectacle apparatus to the spectacle apparatus during the period in which the image frame is displayed. Accordingly, the viewer wearing the spectacles may watch only the video frames A1, A2, ..., An of the content A.

On the other hand, if the spectacle apparatus does not have the right to view the contents, the synchronization signal generator to generate and transmit a synchronization signal 2 for turning on the spectacle apparatus during the period in which the image frame and the sub-frame are displayed and transmit the same to the spectacle apparatus. 140 and the interface unit 150 may be controlled.

Accordingly, the viewer wearing the spectacle device simultaneously watches the image frames A1, A2, ..., An and the subframes A'1, A'2, ..., A'n of the content A, and the subframe. If it is generated with this complementary color frame, only the white screen is viewed. If it is generated to be recognized as white noise, the content A cannot be viewed due to the white noise.

Alternatively, if the spectacle device does not have a viewing authority for the content, the synchronization signal generator 1140 controls to generate the synchronization signals 3 and 4 in the disabled state, and the interface unit 1150 synchronizes the disabled state. It is possible to control to transmit the signals 3 and 4 to the spectacle device.

Here, the synchronization signal in the disabled state means a synchronization signal for always turning on or always turning off the shutter glass as a synchronization signal for not operating the spectacle device.

Accordingly, the viewer wearing the spectacles may not see anything, or may view all the video frames and subframes of the contents A and B, and thus cannot view the contents normally.

If the spectacles do not have the right to view the contents, the interface unit 1150 may be controlled not to transmit the synchronization signal.

Meanwhile, when the spectacle device 1200 is connected to the interface unit 1150 of the display device 1100, the spectacle device 1200 transmits unique identification information to the interface unit 1150. The user may input a selection command for selecting the content view to watch any one of the plurality of content views. When the user selects any one content view, the glasses device 1200 worn by the user and the corresponding content view are mapped. Alternatively, the spectacles may be automatically mapped to one of the plurality of content views. In addition, the controller 1140 may determine whether the corresponding eyeglass device has a viewing authority with respect to the content displayed on the content view, using the identification information received from the eyeglass device 1200.

FIG. 13 is a block diagram illustrating a configuration of a display apparatus 1100 according to another exemplary embodiment.

According to FIG. 13, the display apparatus 1100 includes a plurality of receivers 1110-1, 1110-2,..., 1110-n, a signal processor 1120, a display 1130, and a synchronization signal generator 1140. ), As well as the interface unit 1150 and the controller 1160 may further include a storage unit 1170.

The storage unit 170 stores viewing authority information. In detail, the storage unit 1170 may store viewing authority information for determining whether the spectacle device 1200 is going to view the contents. The viewing authority information stored in the storage unit 1170 may be set and changed by the user. The viewing authority information may be set for each channel, for each content, or for each eyeglass device.

On the other hand, when identification information is received from the spectacles device through the interface unit 1150, the controller 1160 may determine whether the spectacles device has viewing authority using the received identification information and viewing authority information previously stored in the storage unit. . This will be described in detail with reference to FIGS. 14A and 14B.

14A is a diagram illustrating viewing authority information set for each eyeglass device.

In FIG. 14A, # 1, # 2, and # 3 represent identification information unique to the spectacles, and Ch1, Ch2, Ch3, and Ch4 represent a broadcast channel. According to FIG. 14A, it can be seen that viewing authority information is set for each eyeglass device. The spectacle apparatus having the identification information # 1 has viewing authority for the Ch1, Ch2, Ch3 and Ch4 channels. In addition, the spectacle apparatus having the identification information # 2 has viewing rights to the Ch2, Ch3 and Ch4 channels, and the spectacle apparatus having the identification information # 3 has the viewing rights to the Ch1, Ch2 and Ch3 channels.

Here, when the spectacle device 1200 is connected to the interface unit 1150 of the display device 1100, the spectacle device 1200 transmits unique identification information to the interface unit 1150. The user may input a user command to select the content view to watch any one of the plurality of content views. When the user selects any one content view, the glasses device 1200 worn by the user and the corresponding content view are mapped. Alternatively, the spectacles may be automatically mapped to one of the plurality of content views. In addition, the controller 1140 determines whether the corresponding eyeglass device has a viewing authority for the content displayed in the content view, by using the identification information received from the eyeglass apparatus 1200 and the viewing authority information previously stored in the storage unit 1170. can do.

For example, when the glasses device having the identification information # 2 is connected to the interface unit 1150, the identification information # 2 is transmitted to the interface unit 1150. When the user selects one of the plurality of content views, the glasses device having the selected content view and identification information # 2 is mapped. The controller 1160 checks the channel information of the content displayed in the content view, and uses the viewing authority information stored in the storage unit 1170 to determine the viewing authority for the channel of the selected content view. Make sure you have it. If there is no viewing authority for the channel, it may be determined that there is no viewing authority for all contents of the channel.

If the channel information of the content displayed in the content view selected by the user is Ch2, the glasses device having the identification information # 2 has a viewing authority in Ch2, so the controller 1160 determines that the glasses device has the viewing authority for the content. The interface unit 1150 transmits a synchronization signal corresponding to the content view selected by the user to the glasses device.

However, when the channel information of the content displayed in the content view is Ch1, the spectacle device having the identification information # 2 does not have a viewing right with respect to Ch1, so the controller 1160 determines that the spectacle device has no viewing right with respect to the content. In this case, the synchronization signal may not be transmitted to the glasses device, or the synchronization signal in the disabled state may be generated and transmitted to the glasses device. Alternatively, a synchronization signal synchronized with the display timing of the image frame and the subframe of the content may be generated and transmitted to the spectacles.

14B is a diagram illustrating viewing authority information set for each channel.

Referring to FIG. 14B, it can be seen that viewing authority information is set for each channel. Here, the process of restricting the viewing of the content by using the viewing right information is the same as described with reference to FIG. 14A, except that the viewing rights information is only stored.

Here, the viewing authority information may be set and changed by the user. In detail, the user may set viewing authority for each channel or for each glasses device, and change the set viewing authority.

In the above description, the viewing authority information is an example of viewing authority information in which an eyeglass device or a channel having authority is set for each channel or an eyeglass device. Channels and eyeglasses that do not have may be set and stored.

In addition, the viewing authority information is set as an example for each channel or glasses device, but the present invention is not limited thereto, and any method may be used as long as information on viewing authority between the glasses device and the content can be set.

15 is a flowchart illustrating a control method of a display apparatus and an eyeglass apparatus according to another exemplary embodiment.

According to FIG. 15, a plurality of contents are respectively received (S1710). The video frame is configured (S1720). That is, an image frame is formed by processing each of the plurality of received contents. Thereafter, a subframe for limiting viewing of each image frame is generated (S1730). When the sub frame is continuously displayed with the image frame, the sub frame may be combined with the image frame to generate the image frame as a white noise frame. Or it may be generated as a complementary color frame corresponding to the image frame.

In operation S1740, a plurality of content views are displayed. Specifically, a plurality of content views are displayed by combining the image frame and the sub frame. Thereafter, a synchronization signal for synchronizing the spectacles device is generated (S1750). Specifically, a synchronization signal for synchronizing the eyeglasses with the output timing of the content view mapped with the eyeglasses among the plurality of content views is generated. In operation S1760, it is determined whether the spectacle device has the viewing authority with respect to the content displayed in the content view.

If the spectacle device has the viewing authority for the content (S1760-Y), the viewing of the content is allowed (S1770). Specifically, a sync call signal for turning on the eyeglasses during the period in which the image frame is output may be transmitted to the eyeglasses.

If the spectacle device does not have the right to view the content (S1760-N), viewing of the content is restricted (S1780). Specifically, the synchronization signal for the glasses device is not transmitted, the synchronization signal in the disabled state is generated and transmitted, or the synchronization signal for turning on the glasses device during the display period of the image frame and the subframe is generated. Can be transmitted to the spectacle device.

Here, when determining whether the spectacle apparatus has viewing authority, when identification information is received from the spectacle apparatus, it may be determined whether the spectacle apparatus has viewing authority using the identification information and previously stored viewing authority information. The viewing authority information can be set and changed by the user.

Accordingly, when providing a plurality of images to a plurality of viewers, viewing of the content can be restricted for each viewer, and the viewer who has limited viewing cannot view the restricted content image even if the viewer views the display screen without glasses.

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

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