As such, when the output sink is set to 60 Hz, the relative arrangement position of each image frame of the first content may be determined by being divided into 0.5 units.

Up to now, each configuration of the display device according to the present invention has been described in detail. Hereinafter, a method of performing a multi-view display on a plurality of contents in the display apparatus according to the present invention will be described in detail.
15 is a flowchart of a multi-view display method in a display device according to an embodiment of the present invention.
As shown in FIG. 15, the display apparatus receives first content and second content having a frame rate smaller than the first content (S1510). Thereafter, the display apparatus stores the received first content and the second content in the storage unit, and processes the first content and the second content stored in the storage unit through the first signal processor and the second signal processor to process the first content and the second content. An image frame for the second content is generated (S1520 and S1530). Thereafter, the display apparatus compares the difference between the frame rate of the first content and the frame rate of the second content through the second signal processor, and interpolates the image frame of the second content according to the comparison result (S1540).
Thereafter, the display apparatus displays a combination of alternately arranged image frames of the second content generated by interpolating the image frame of the first content and the image frame of the second content generated by the first signal processor (S1550). . Accordingly, the display device according to the present invention can perform multi-view display on a plurality of contents.
In detail, the display apparatus receives the first content and the second content through the first and second receivers. Here, the first content and the second content may be transmitted from an external broadcast channel or provided from a source device such as a web server or a reproduction device such as a DVD device. One of the first content and the second content may have a smaller frame rate than another content. In the present invention, it will be described under the assumption that the frame rate of the second content has a smaller frame rate than the frame rate of the second content.
When the first content and the second content are received through the first and second receivers, the display apparatus stores the received first content and the second content in the storage unit. When the first content and the second content are stored in the storage unit, the display apparatus generates an image frame for the first content and the second content stored in the storage unit through the first signal processor and the second signal processor. An operation of generating an image frame for the first content and the second content by the first signal processor and the second signal processor has been described in detail with reference to FIG. 13, and thus, a detailed description thereof will be omitted.
When an image frame for the first content and the second content is generated through the first signal processor and the second signal processor, the display device stores the generated image frame for the first content and the second content in the storage unit. . Subsequently, the display apparatus compares the frame rate of the image frame of the first content and the frame rate of the image frame of the second content stored in the storage to interpolate the image frame of the second content to interpolate the image of the second content. Create a frame.
In detail, the display apparatus may interpolate an image frame of the second content by comparing a relative arrangement position between each image frame of the first content and the second content based on the output sink. Here, the output sink refers to a synchronized signal for an image frame in which image frames of the first content and the second content are alternately displayed. Such an output sink may be set to a frame rate of the first content having a frame rate larger than that of the second content or may be set according to information input from the outside.
Accordingly, the display device may know a relative arrangement position between each image frame of the first content and the second content based on the output sink set according to the condition. As described with reference to FIG. 14, an image frame of the first content may be set to a frame rate of 30 Hz, and an image frame of the second content may be set to a frame rate of 24 Hz. The output sync for the image frames of the first content and the second content may be set to 60 Hz.
As such, when the output sink is set to 60 Hz, the relative arrangement position of each image frame of the first content may be determined by being divided into 0.5 units. That is, the position where the output sink is set to 60 Hz relative to the image frame of the first content corresponding to the
Meanwhile, the display apparatus may determine the relative arrangement position from the output sink by referring to the number of lines for the image frames of the first content and the second content or the image frame information of the first content and the second content. For example, the entire input line of the image frame for the second content may be 1125 lines, and the 112th line of the image frame for the second content may be stored in the current storage unit. As such, when an output sink occurs at a time point when the 112th line of the entire input lines of the image frame for the second content is stored in the storage unit, the display apparatus displays the current storage unit in the entire input line of the image frame for the second content. By dividing the lines stored in, the resulting value 3.1 is calculated. From this result, it is possible to know a relative arrangement position of the image frame of the second content with respect to the time point at which the output sink is generated.
Such a display device can know the relative arrangement position of the image frame of the first content with respect to the time when the output sink is generated through the method described above. As such, when a relative arrangement position between each image frame of the first content and the second content is obtained based on an output sink according to a preset condition, the display apparatus may determine a relative relationship between each image frame of the first content and the second content that have been acquired. The image frames of the second content may be interpolated by comparing the arrangement positions.
Such a display device performs interpolation to generate an image frame of the second content corresponding to a point corresponding to a relative arrangement position of the first content with reference to the front and back image frames. However, the present invention is not limited thereto, and the display apparatus may interpolate an image frame for the second content according to a reception time of the first content and the second content. In detail, when the first content and the second content are received, the display apparatus compares the reception time points of the received first content and the second content, and corresponds to a time point when one image frame of the first content is stored in the storage unit. The storage ratio of the corresponding frame of the second content is checked. Thereafter, the display apparatus generates an interpolation frame by combining the corresponding frame of the second content and the next frame of the corresponding frame according to the identified storage ratio.
Such a display device estimates and estimates the motion of an object displayed in the frame by comparing the next frame with the corresponding frame of the second content corresponding to the time when one image frame of the image frame of the first content is stored in the storage unit. The interpolation frame may be generated by applying a reception ratio to the motion.

In addition, the content received by the plurality of receivers 2110-1, 2110-2,..., 2110-n 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.

The key frame can be detected. For example, if the current frame is repeated three times and the next frame is repeated two times, the detection units 2120-1, 2120-2,..., 2120-n display the input content on the

The offset time is delay information from the reference time set for each content to the opening or the turning off of the shutter glass. That is, the spectacle apparatus opens / offs the left eye shutter glass and the right eye shutter glass when the offset time has elapsed from the reference time point.
For example, the reference time point may be a time point at which a vertical sync signal (ie, frame sync) is generated in an image frame, and information about the reference time point may be included in a transport packet.

25 is a flowchart illustrating a content providing method of a display apparatus according to another exemplary embodiment.
First, a plurality of contents are received (S2310). In detail, a plurality of contents having different frame rates may be received.
Thereafter, a key frame of each of the plurality of contents is detected (S2320).
For example, when an image frame constituting the content is input at a frame rate of 24 frames per second or 30 frames per second, each frame may be detected as a key frame.
On the other hand, when an image frame constituting the content is input at a frame rate of 60 frames per second, a key frame may be detected by extracting a pull-down method of the input frame. For example, if the current frame is repeated three times and the next frame is repeated two times, it is determined that the input content is converted to a 3: 2 pull-down method, and one frame and two frames are repeated in the three repeated frames. One frame in the frame is detected as a key frame.
Then, the detected key frame is integrated (S2330). In detail, when the number of key frames of each of the plurality of contents is different, the number of key frames may be matched by performing a frame skip operation, and frames corresponding to each other of the contents may be integrated.
In this case, a key frame of each of the plurality of contents may be integrated into a top to bottom, side by side format, or checker board format. Since each of these embodiments has been described above, a redundant description thereof will be omitted.
Then, signal processing for the integrated key frame is performed (S2340). That is, the motion judging removal process can be performed by interpolating the integrated key frame. Specifically, Frame Rate Control (FRC) is performed to convert the frame rate of the integrated key frame into a frame rate displayable on the display device. For example, in the case of the National Television System Committee (NTSC) scheme, the frame rate displayable on the
In this case, the interpolated frame is generated by estimating the motion of the object included in the current frame and the next frame in the integrated key frame, and the generated interpolation frame is inserted between the current frame and the next frame, thereby the frame rate of the integrated key frame. Can be converted to a frame rate displayable on the display device.
Meanwhile, a frame in which the frame rate is converted is divided for each content, and each frame may be up or down scaled according to the screen size of the display apparatus using a scaler.
In operation S2350, the multi-view frame is displayed using the processed key frame. In detail, the multi-view frame may be displayed by multiplexing the image frames for each content to be arranged alternately at least one.
For example, in the case of a shutter glass type display apparatus, at least one image frame of the first content, the image frame of the second content, ..., and the image frame of the nth content are configured to be alternately arranged and displayed. In this case, when the processed frame rate is 60 Hz, each content is displayed at n × 60 Hz, and the user can watch a desired content by wearing an eyeglass device (not shown) that is linked to the timing at which the content is displayed. .
Meanwhile, when using a plurality of 3D contents, the left eye image and the right eye image included in each 3D content may be multiplexed in a predetermined arrangement, and alternately arranged with an image frame of another content.
In detail, when the display apparatus operates at 60 Hz, the left eye image, the right eye image, the left eye image, the right eye image of the second content, the left eye image and the right eye image of the n-th content are sequentially arranged. It can be displayed at a driving frequency of 2 x n x 60 Hz. The user recognizes a left eye image and a right eye image of one 3D content through the glasses device.
In addition, the content providing method according to the present embodiment may further include generating a synchronization signal for synchronizing the glasses device corresponding to each content according to the display timing of each content, and transmitting the synchronization signal to the glasses device. .
Specifically, in the multi-view mode, a synchronization signal for synchronizing the spectacle apparatus with the display timing of the image frame for one of the plurality of contents is generated, and in the normal mode, the display timing of the left eye image frame and the right eye image frame of the 3D content Generate a synchronization signal for synchronizing the spectacles device.
In addition, communication with the eyeglasses device may be performed according to various wireless communication methods to transmit a corresponding synchronization signal. Since the case in which the synchronization signal is transmitted through the Bluetooth communication method has been described above, redundant description will be omitted.
[Example using multiple SoCs]
As described above, in order to process a plurality of contents, a large number of components should be provided in comparison with the processing of one content. In particular, in order to effectively provide a multi-view, a plurality of display processors may be provided.
