However, the present invention is not limited thereto, and in the case of a polarized glass display device, the video output unit 131 may output an image of each content output from the first to third signal processing units 120-1 to 120-3. Multiplexing is performed to blend the frames horizontally, vertically, or diagonally. Thereafter, the video output unit 131 configures and displays a multi-content frame in which image frames for each content are combined by upscaling an image frame for each multiplexed content to a screen size.
In this case, the spectacles 200 may be polarized glasses, and each of the plurality of users may view a video image of different contents through the polarized glasses worn by the user.
Meanwhile, in the above-described shutter glass type display apparatus, a mode of alternately arranging and displaying image frames of each content may be referred to as a multi view mode or a dual view mode. Hereinafter, the mode will be described as a multi view mode. . As described above, when the display apparatus 100 operates in a normal mode (or a single view mode) displaying only one of 2D content or 3D content, the first to third receivers 111 to 113 may be configured. Only one can be active to process content.
Meanwhile, the above-described content may be 2D content or 3D content. Here, 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 contents, the video output unit 131 may include a left eye image and a right eye included in each 3D content provided by each frame rate converter of the first to third signal processors 120-1 to 120-3. 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 spectacle device 200. Through this, the left eye image and the right eye image of one content are recognized.
The audio output unit 132 may output audio to the outside by transmitting an audio signal to a short channel speaker or a multi channel speaker such as 5.1 channel and 7.1 channel. Alternatively, the audio output unit 132 may transmit an audio signal to the spectacle device 200 through the interface unit 150 to be described later. That is, each audio data output from the audio output unit 132 is provided to the user through an output means such as an earphone provided in the spectacles 200, or a single channel or multichannel speaker provided in the display apparatus 100.

The audio output unit 132 will be described in detail later.
Meanwhile, the controller 160 operates according to a mode selected by the user among the single view mode and the multi view mode, and when the multi view mode is selected by the user, the first to third receivers 111 to 113 to receive a plurality of contents. And control the respective components, that is, the signal processor 120 and the output unit 130. Specifically, when a selection command for the single view mode is input from the user, the controller 160 controls the first to third receivers 111 to 113 to receive only one of a plurality of contents. In addition, the controller 160 controls the signal processor 120 to perform signal processing on the content received by one of the first to third receivers 111 to 113. For example, when content is received from the first receiver 111, the controller 160 may include video data and audio data included in the content by the first signal processor 120-1 corresponding to the first receiver 111. Control to perform signal processing for. Thereafter, the controller 160 controls the output unit 130 to output the video data and the audio data processed by the first signal processor 120-1 through the video output unit 131 and the audio output unit 132. do.
Meanwhile, when a selection command for the multi-view mode is input from the user, the controller 160 controls the first to third receivers 111 to 113 to receive a plurality of contents. In addition, the controller 160 controls the video data and the audio data included in each content in the first to third signal processors 120-1 to 120-3 corresponding to the first to third receivers 111 to 113. Control to perform signal processing. According to the control command of the controller 160, each of the first video processor 123-1 included in the first signal processor 120-1 and the video processor included in the remaining signal processor, as described above, The video data included in each content received through the first to third receivers 111 to 113 may be signal processed.
Meanwhile, if the audio data of each content is data having a predetermined number or more of audio output channels, the controller 160 processes each audio data into two channels of stereo audio signals, and has less than a predetermined number of audio output channels. If it is data, the first audio processor 124-1 and the remaining audio processor may be controlled to signal the audio data into a stereo audio signal corresponding to the number of channels. Therefore, each of the first audio processor 124-1 and the other audio processor may signal-process audio data of each content into a stereo audio signal and output the same.
Hereinafter, an operation in which the first audio processing unit 124-1 processes the audio data into two audio signals in stereo audio signals in the case of more than a predetermined number of audio output channels will be described.
FIG. 5 is an exemplary diagram illustrating signal processing of audio data having a 5.1 channel into a stereo audio signal of two channels in an audio processor according to an embodiment of the present invention, and FIG. 6 is a diagram illustrating an audio processor according to another embodiment of the present invention. It is an exemplary figure which processes the audio data which has 7.1 channel into a stereo audio signal of 2 channels.
As described above, the first signal processor 120-1 includes a first audio processor 124-1, and the first audio processor 124-1 is applied to the content received through the first receiver 111. Signal processing is performed on the included audio data. The first audio processor 124-1 may signal-process audio data included in content received through the first receiver 111 as a stereo audio signal according to the number of audio output channels and output the same.
Specifically, as illustrated in FIG. 5, the audio output unit 132 of the display apparatus 100 may include six speakers (center 510, woofer 520, left and right fronts 530-1, 530-2 through 5.1 channels). ), Audio signals may be output to the left and right rear 540-1 and 540-2. As such, when outputting audio signals to six speakers through the 5.1 channel, the first audio processor 124-1 corresponds to a specific channel (for example, left and right fronts 530-1 and 530-2) among the 5.1 channels. Only audio data for a channel) is processed. That is, the first audio processor 124-1 weights only audio data of a specific channel (left and right fronts 530-1, 530-2) among 5.1 channels through the first and second weighting units 560-1, 560-2. Signal is processed after applying the weighted average. Accordingly, the audio output unit 132 may apply a weighted average to the audio signals output through two channels among the 5.1 channels, that is, the left front 530-1 and the right front 530-1.
As illustrated in FIG. 6, the audio output unit 132 of the display apparatus 100 has eight speakers (center 510, woofer 520, left and right fronts 530-1, 530-2) through 7.1 channels. , Audio signals may be output to the left and right rear 540-1 and 540-2 and the left and right mediums 550-1 and 550-2. As such, when outputting audio signals to eight speakers through the 7.1 channel, the first audio processor 124-1 corresponds to a specific channel (for example, left and right rears 540-1 and 540-2) among the 7.1 channels. Only audio data for a channel) is processed. That is, the first audio processor 124-1 weights only audio data for a specific channel (left and right rears 540-1, 540-2) among 7.1 channels through the first and second weighting units 560-1, 560-2. Signal is processed after applying the weighted average. Therefore, the audio output unit 132 may apply a weighted average to the audio signals output through two channels among the 7.1 channels, that is, the left rear 540-1 and the right rear 540-1.
Thereafter, the controller 160 outputs each video data and audio data processed by the first to third signal processing units 120-1 to 120-3 through the video output unit 131 and the audio output unit 132. The output unit 130 is controlled to be. According to the control command of the controller 160, the video output unit 131 is arranged to combine the video data processed by the first to third signal processing units 120-1 to 120-3 in image frame units. To display. Meanwhile, the audio output unit 132 converts each audio signal processed by the first to third signal processing units 120-1 to 120-3 into one audio stream according to a control command of the controller 160. Each audio signal transmitted through one channel or signal processed without a separate audio stream conversion may be output through a plurality of channels.
Specifically, unless the size of the audio signal signal-processed from each of the audio processing units 124 included in the first to third signal processing units 120-1 to 120-3 is converted into a stereo audio signal of two channels, The audio output unit 132 may output each audio signal processed through a plurality of channels.
On the other hand, if the size of the audio signal signal-processed from each of the audio processing unit 124 included in the first to third signal processing unit (120-1 ~ 120-3) is reduced to fit to the stereo audio signal of two channels The audio output unit 132 may convert each reduced-converted audio signal into one audio stream and output the single audio stream.
Meanwhile, in FIG. 2, 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 glasses device 200 at the display timing of the image frame for each content in the multi-view mode.
The interface unit 150 transmits the synchronization signal generated from the synchronization signal generator 140 to the spectacles 200. In this case, the interface unit 150 may transmit the synchronization signal to the eyeglasses 200 in various ways.
According to an embodiment of the present disclosure, the interface unit 150 includes a Bluetooth communication module to communicate with the glasses device 200, and converts the synchronization signal generated from the synchronization signal generator 140 into a transmission packet according to the Bluetooth communication standard. It may be generated and transmitted to the spectacles 200. In this case, the transport packet includes time information for turning on / off the left eye and right eye shutter glasses of the spectacles 200 in synchronization with the display timing of the plurality of contents. Specifically, the time information included in the transport packet includes an offset time for turning on the left eye shutter glass of the spectacle apparatus 200, a left shutter close offset for turning off the left eye shutter glass, and a right eye shutter glass. It may include information about an offset time for turning on (right shutter open offet), the right time for turning off the right eye shutter glass (right shutter open offset).
The offset time is delay information from the reference time set for each content to the on or off time of the left eye and right eye shutter glasses. That is, when the offset time elapses from the reference time point, the spectacle apparatus 200 turns on / off the left eye and right eye shutter glasses. For example, the reference time point may be a time point at which a vertical synchronization signal (ie, frame sync) is generated in an image frame. The information about the reference time point may be included in the transport packet, and the eyeglasses 200 may turn on / off the left eye and right eye shutter glasses based on the information about the reference time point included in the received transport packet. It is possible to set the time when is generated.
Meanwhile, the interface unit 150 transmits / receives a Bluetooth address and a pin code with each glasses device 200 to perform pairing according to a Bluetooth communication method. When pairing is completed, the interface unit 150 may register information about each eyeglass apparatus 200, for example, identification information of the eyeglass apparatus 200. Thereafter, the interface unit 150 may match display timing of each content with information about the glasses device and transmit a transmission packet to the corresponding glasses device 200 based on the identification information obtained through pairing.
The eyeglass apparatus 200 receiving the transmission packet may check the display timing based on the information included in the received transmission packet, and turn on / off the left and right eye shutter glasses according to the confirmed display timing.
For example, in a state where image frames of contents 1 and 2 are alternately displayed, the interface unit 150 generates a transmission packet according to the Bluetooth communication standard by using the synchronization signal generated from the synchronization signal generator 140. To the first and second eyeglasses 200. The transmission packet transmitted to the first glasses apparatus 200 includes time information and information on a reference time point for operating the left and right eye shutter glasses of the first glasses apparatus 200 to be turned on at the display timing of the content1. The packet transmitted to the second eyeglass apparatus 200 includes time information and reference time information for operating the left eye and right eye shutter glasses of the first eyeglass apparatus 200 to be turned on at the display timing of the content 1.
Accordingly, the first glasses apparatus 200 turns on the left and right eye shutter glasses at the display timing at which the image frame of the content 1 is displayed based on the information included in the received transmission packet, and displays the image frame of the content 2 on the display timing. The left eye and right eye shutter glasses can be turned off at the timing.
Meanwhile, the second glasses apparatus 200 turns on the left and right eye shutter glasses at the display timing at which the image frame of the content 2 is displayed based on the information included in the received transmission packet, and displays the image frame of the content 1 on the display timing. The left eye and right eye shutter glasses can be turned off at the timing.
Thus, a user wearing the first spectacles 200 may view a video image of content 1, and a user wearing the second spectacles 200 may view a video image of content 2.
According to another embodiment, the interface unit 150 may provide an IR (Infra Red) synchronization signal or an RF (Radio Frequency) synchronization signal having a different radio frequency channel to the eyeglasses 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 alternately repeats the high level during the first period and the low level during the second period at predetermined time intervals based on the information included in the synchronization signal. The infrared signal may be transmitted to the spectacles 200. Thus, the spectacle apparatus 200 may be implemented to turn on the shutter glass during the first period at the high level and to turn off the shutter glass during the second period at the low level. In addition, the synchronization signal may be generated in various ways.
In the above-described embodiment, the interface unit 150 and the eyeglasses 200 have been described as communicating by the Bluetooth communication method or by the IR or RF method, but 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. .

Let's do it. Accordingly, a user wearing the spectacles 200 may view a video image of one content.
Meanwhile, in the case of 3D content, the first shutter glass unit 250 and the second shutter glass unit 260 may alternately open and close each glass. That is, the first shutter glass unit 250 may be opened at the timing when the left eye image constituting one 3D content is displayed according to the driving signal, and the second shutter glass unit 260 may be opened at the timing when the right eye image is displayed. The input unit 240 may receive a user manipulation command such as channel conversion or volume adjustment according to the user manipulation.
