The video decoder 225 decodes the demultiplexed video signal and the scaler 235 performs scaling so that the resolution of the decoded video signal can be output from the display 180.

The video decoder 225 may include a decoder of various standards.

On the other hand, the image signal decoded by the image processing unit 320 can be divided into a case where there is only a 2D image signal, a case where a 2D image signal and a 3D image signal are mixed, and a case where there is only a 3D image signal.

For example, when an external video signal input from the external device 190 or a broadcast video signal of a broadcast signal received from the tuner unit 110 includes only a 2D video signal, when a 2D video signal and a 3D video signal are mixed And a case where there is only a 3D video signal. Accordingly, the controller 170, particularly, the image processing unit 320 and the like can process the 2D video signal, the mixed video signal of the 2D video signal and the 3D video signal, , A 3D video signal can be output.

Meanwhile, the image signal decoded by the image processing unit 320 may be a 3D image signal in various formats. For example, a 3D image signal composed of a color image and a depth image, or a 3D image signal composed of a plurality of view image signals. The plurality of viewpoint image signals may include, for example, a left eye image signal and a right eye image signal.

5, the format of the 3D video signal is a side-by-side format (FIG. 5A) in which the left eye image signal L and the right eye image signal R are arranged left and right, A frame sequential format (FIG. 5C) in which time division is arranged (FIG. 5C), an interlaced format in which the left eye image signal and the right eye image signal are mixed line by line 5d), a checker box format (FIG. 5e) in which the left eye image signal and the right eye image signal are mixed box by box, and the like.

The processor 330 may control the overall operation in the image display apparatus 100 or in the control unit 170. [ For example, the processor 330 may control the tuner 110 to select a channel selected by the user or an RF broadcast corresponding to a previously stored channel.

In addition, the processor 330 may control the image display apparatus 100 by a user command or an internal program input through the user input interface unit 150. [

The processor 330 may control operations of the demultiplexing unit 310, the image processing unit 320, the OSD generating unit 340, and the like in the controller 170.

The OSD generation unit 340 generates an OSD signal according to a user input or by itself. For example, based on a user input signal, a signal for displaying various information in a graphic or text form on the screen of the display 180 can be generated. The generated OSD signal may include various data such as a user interface screen of the video display device 100, various menu screens, a widget, and an icon. In addition, the generated OSD signal may include a 2D object or a 3D object.

The OSD generating unit 340 can generate a pointer that can be displayed on the display based on the pointing signal input from the remote control device 200. [ In particular, such a pointer may be generated by a pointing signal processing unit, and the OSD generating unit 240 may include such a pointing signal processing unit (not shown). Of course, a pointing signal processing unit (not shown) may be provided separately from the OSD generating unit 240.

At this time, the OSD signal and the decoded video signal may include at least one of a 2D signal and a 3D signal. The mixed video signal is supplied to a frame rate converter 350.

A frame rate converter (FRC) 350 can convert the frame rate of an input image. On the other hand, the frame rate converter 350 can output the frame rate without conversion.

The formatter 360 may arrange the left eye image frame and the right eye image frame of the frame rate-converted 3D image. The left eye glass of the 3D viewing apparatus 195 and the synchronization signal Vsync for opening the right eye glass can be output.

The formatter 360 receives the mixed signal, i.e., the OSD signal and the decoded video signal, from the mixer 345, and separates the 2D video signal and the 3D video signal.

In the present specification, a 3D video signal means a 3D object. Examples of the 3D object include a picuture in picture (PIP) image (still image or moving picture), an EPG indicating broadcasting program information, Icons, texts, objects in images, people, backgrounds, web screens (newspapers, magazines, etc.).

On the other hand, the formatter 360 can change the format of the 3D video signal. For example, it may be changed to any of the various formats illustrated in FIG. Thus, according to the format, the operation of the eyeglass type viewing apparatus can be performed as shown in Fig.

That is, when the left eye image L is displayed on the display 180, the left eye glass of the shutter glass 195 is opened and the right eye glass is closed. When the right eye image R is displayed, The left eye glass is closed, and the right eye glass is opened.

6 (b) illustrates the operation of the 3D-use glass 195, particularly the polarizing glass 195, when the formatter 360 arranges and outputs the side-by-side format of the format of Fig. On the other hand, the 3D glass 195 applied in FIG. 6 (b) may be a shutter glass, and the shutter glass at this time may be operated as a polarizing glass while keeping both the left-eye glass and right-eye glass open .

Meanwhile, the formatter 360 may convert the 2D video signal into a 3D video signal. For example, according to a 3D image generation algorithm, an edge or a selectable object is detected in a 2D image signal, and an object or a selectable object according to the detected edge is separated into a 3D image signal and is generated . At this time, the generated 3D image signal can be separated into the left eye image signal L and the right eye image signal R, as described above.

Although not shown in the drawing, it is also possible that a 3D processor (not shown) for 3-dimensional effect signal processing is further disposed after the formatter 360. The 3D processor (not shown) can process the brightness, tint, and color of the image signal to improve the 3D effect. For example, it is possible to perform signal processing such as making the near field clear and the far field blurring. On the other hand, the functions of such a 3D processor can be merged into the formatter 360 or merged into the image processing unit 320. [ This will be described later with reference to FIG. 7 and the like.

Meanwhile, the audio processing unit (not shown) in the control unit 170 can perform the audio processing of the demultiplexed audio signal. To this end, the audio processing unit (not shown) may include various decoders.

However, May be located behind the formatter. That is, the output of the image processing unit 320 is 3D-processed by the formatter 360, and the OSD generating unit 340 performs 3D processing together with the OSD generation. Thereafter, the processed 3D signals are mixed by the mixer 345 It is also possible to do.

Meanwhile, the block diagram of the controller 170 shown in FIG. 4 is a block diagram for an embodiment of the present invention. Each component of the block diagram can be integrated, added, or omitted according to the specifications of the control unit 170 actually implemented.

In particular, the frame rate converter 350 and the formatter 360 are not provided in the controller 170, but may be separately provided.

7 is a diagram illustrating various scaling methods of a 3D image signal according to an embodiment of the present invention.

Referring to the drawing, in order to increase the 3-dimensional effect, the controller 170 may perform 3D effect signal processing. In particular, it is possible to perform a size adjustment or a tilt adjustment of a 3D object in a 3D image.

The 3D object 510 in the 3D image signal or the 3D image signal can be enlarged or reduced 512 as a whole at a certain rate as shown in FIG. 7 (a) , The 3D object may be partially enlarged or reduced (trapezoidal shape, 514, 516). 7 (d), at least a portion of the 3D object may be rotated (parallelogram shape 518). This scaling (scaling) or skew adjustment can emphasize the 3D effect of a 3D object in a 3D image or a 3D image, that is, a 3D effect.

On the other hand, as the slope becomes larger, the difference in length between the parallel sides of the trapezoidal shapes 514, 516 becomes larger as shown in Fig. 7 (b) or 7 (c) .

The size adjustment or the tilt adjustment may be performed after the 3D image signal is aligned in a predetermined format in the formatter 360. [ Or in the scaler 235 in the image processing unit 320. [ On the other hand, the OSD generating unit 340 may generate an object in a shape as illustrated in FIG. 7 for the OSD generated to enhance the 3D effect.

Though not shown in the drawing, signal processing for a 3D effect (3-dimensional effect) may be performed by adjusting the brightness, tint, and brightness of an image signal or object, It is also possible that signal processing such as color adjustment is performed. For example, it is possible to perform signal processing such as making the near field clear and the far field blurring. The signal processing for the 3D effect may be performed in the controller 170 or may be performed through a separate 3D processor. Particularly, when it is performed in the control unit 170, it is possible to perform it in the formatter 360 or in the image processing unit 320 together with the above-described size adjustment or tilt adjustment.

FIG. 8 is a view for explaining how images are formed by the left eye image and the right eye image, and FIG. 9 is a view for explaining the depth of a 3D image according to the interval between the left eye image and the right eye image.

First, referring to FIG. 8, a plurality of images or a plurality of objects 615, 625, 635, and 645 are illustrated.

First, the first object 615 includes a first left eye image 611 (L) based on the first left eye image signal and a first right eye image 613 (R) based on the first right eye image signal, It is exemplified that the interval between the first left eye image 611, L and the first right eye image 613, R is d1 on the display 180. [ At this time, the user recognizes that an image is formed at an intersection of an extension line connecting the left eye 601 and the first left eye image 611 and an extension line connecting the right eye 603 and the first right eye image 603. Accordingly, the user recognizes that the first object 615 is positioned behind the display 180. [

Next, since the second object 625 includes the second left eye image 621, L and the second right eye image 623, R and overlaps with each other and is displayed on the display 180, do. Accordingly, the user recognizes that the second object 625 is located on the display 180. [

Next, the third object 635 and the fourth object 645 are arranged in the order of the third left eye image 631, L, the second right eye image 633, R, the fourth left eye image 641, Right eye image 643 (R), and their intervals are d3 and d4, respectively.

According to the above-described method, the user recognizes that the third object 635 and the fourth object 645 are positioned at positions where the images are formed, respectively, and recognizes that they are located before the display 180 in the drawing.

At this time, it is recognized that the fourth object 645 is projected before the third object 635, that is, more protruded than the third object 635. This is because the interval between the fourth left eye image 641, L and the fourth right eye image 643, d4 is larger than the interval d3 between the third left eye image 631, L and the third right eye image 633, R. [

Meanwhile, in the embodiment of the present invention, the distance between the display 180 and the objects 615, 625, 635, and 645 recognized by the user is represented by a depth. Accordingly, it is assumed that the depth when the user is recognized as being positioned behind the display 180 has a negative value (-), and the depth when the user is recognized as being positioned before the display 180 (depth) has a negative value (+). That is, the greater the degree of protrusion in the user direction, the greater the depth.

9, the interval a between the left eye image 701 and the right eye image 702 in FIG. 9A is smaller than the interval between the left eye image 701 and the right eye image 702 shown in FIG. 9 (b) it is understood that the depth a 'of the 3D object in FIG. 9 (a) is smaller than the depth b' of the 3D object in FIG. 9 (b).

In this way, when the 3D image is exemplified as the left eye image and the right eye image, the positions recognized as images are different depending on the interval between the left eye image and the right eye image. Accordingly, by adjusting the display intervals of the left eye image and the right eye image, the depth of the 3D image or the 3D object composed of the left eye image and the right eye image can be adjusted.

The pointer 205 displayed on the display 180 of the video display device corresponds to the movement of the remote control device 200. [ As shown in the figure, the remote controller 200 can be referred to as a space remote controller or a 3D pointing device because the pointer 205 is moved and displayed according to the movement in the 3D space.

10B illustrates that when the user moves the remote control device 200 to the left, the pointer 205 displayed on the display 180 of the video display device moves to the left correspondingly.

The image display apparatus can calculate the coordinates of the pointer 205 from the information on the motion of the remote control apparatus 200. [ The image display apparatus can display the pointer 205 so as to correspond to the calculated coordinates.

10C illustrates a case where the user moves the remote control device 200 away from the display 180 while the specific button in the remote control device 200 is depressed. Thereby, the selected area in the display 180 corresponding to the pointer 205 can be zoomed in and displayed. Conversely, when the user moves the remote control device 200 close to the display 180, the selection area within the display 180 corresponding to the pointer 205 may be zoomed out and zoomed out. On the other hand, when the remote control device 200 moves away from the display 180, the selection area is zoomed out, and when the remote control device 200 approaches the display 180, the selection area may be zoomed in.

On the other hand, when the specific button in the remote control device 200 is pressed, it is possible to exclude recognizing the up, down, left, and right movement. That is, when the remote control apparatus 200 moves away from or approaches the display 180, it is not recognized that the up, down, left, and right movements are recognized, and only the forward and backward movements are recognized. Only the pointer 205 is moved in accordance with the upward, downward, leftward, and rightward movement of the remote control device 200 in a state where the specific button in the remote control device 200 is not pressed.

On the other hand, the moving speed and moving direction of the pointer 205 may correspond to the moving speed and moving direction of the remote control device 200.

First, the image display apparatus 100 receives a broadcast signal from the set-top box 250 through the external apparatus interface unit 130 (S1310).

As shown in FIG. 1, the set-top box 250 in the video system 10 receives a broadcast signal. The received broadcast signal may be a terrestrial broadcast signal, a satellite broadcast signal, a cable broadcast signal, or the like. The received broadcast signal may be a 2D broadcast signal or a 3D broadcast signal.

The image display apparatus 100 receives the broadcast signal received from the set-top box 250 through the external device interface unit 130. [ Then, the received broadcast signal is transmitted to the controller 170.

On the other hand, the set-top box 250 can receive a broadcast signal through the broadcast receiver 272 as shown in FIG. The received broadcast signal is transmitted to the signal processing unit 260 and the video display device 100 can receive the broadcast signal from the set top box 250 through the external device interface unit 130.

The control unit 170 may control the display 180 to display the broadcast image by processing the broadcast signal received from the external device interface unit 130.

At this time, the display display mode may be the external input display mode. For example, if the display mode is an 'antenna' mode, a 'cable' mode, a 'USB' mode, a 'component' mode, a 'RGB- Lt; / RTI >

For example, the controller 170 generates an object indicating the external input display mode, for example, 'HDMI', and the control unit 170 displays the object together with the broadcast image Can be controlled. Thus, the user can know that the broadcast image is displayed through the external input.

Alternatively, step 1315 (S1315) may be performed between step 1350 (S1350) and step 1360 (step 1360), unlike the figure.

On the other hand, step 1315 (S1315) can correspond to step 1515 (S1515) of Fig.

Next, an image including broadcast information or broadcast information included in the broadcast signal is extracted (S1320). Then, the extracted broadcast information or image is transmitted to the server (S1330).

The control unit 170 extracts an image including broadcast information or broadcast information included in the broadcast signal.

For example, if the broadcast signal received from the set-top box 250 is a stream, the demultiplexer 310 in the controller 170 demultiplexes the stream, and if broadcast information is included in the demultiplexed stream , Broadcast information can be extracted.

The broadcast information at this time may include channel information, program information, broadcast time information, and the like.

In another example, when the broadcast signal received from the set-top box 250 does not include broadcast information, the controller 170 extracts a broadcast image from the broadcast signal. Specifically, the demultiplexing unit 310 in the control unit 170 extracts a broadcast image, and the image processing unit 320 can extract an area including broadcast information in the broadcast image.

At this time, the region including the broadcast information in the broadcast image can correspond to the outer region of the broadcast image region. Normally, an object representing a broadcast channel or an object representing a program name may be arranged in a right upper end region or a left upper end region in a broadcast video.

For example, when the same text or graphics are displayed for a predetermined time in the outer area, it can be interpreted that an image representing broadcasting information is included in the area. Accordingly, the control unit 170 can extract an image including the area as an image representing broadcast information.

The control unit 170 controls the extracted broadcast information or image to be transmitted to the server 500 through the network interface unit 135.

Next, the server 500 receives an image including broadcast information or broadcast information from a plurality of video display devices (S1430).

The network interface unit 730 of the server 500 can receive the real-time broadcast image through the network. Such a real-time broadcast image may be received from a separate image server or received from a broadcast station. This real-time broadcast image can be used as a plurality of still images for comparison with an image including broadcast information received from a plurality of video display devices.

The processor 720 of the server 500 may generate real-time viewership information using real-time broadcast information received from a plurality of video display devices. The real-time viewership information at this time may include channel share information, channel viewer number information, broadcast program share information of a specific channel, information on the number of viewers of a specific channel, and the like. In addition, it may include real-time channel search information, real-time program search information, and the like.

The processor 720 of the server 500 extracts broadcast information such as channel information, program information, and the like from the broadcast image in the case of real-time broadcast image, and, based on the extracted broadcast information, Real-time viewership information, and the like.

Step 1435 (S1435) corresponds to step 1535 (S1535) of FIG. 15, and step 1440 (S1440) corresponds to step 1540 (S1540) of FIG.

Next, the server 500 transmits the real-time viewership information to at least one of the plurality of video display periods (S1450). Correspondingly, the video display apparatus 100 receives real-time rating information from the server (S1350). Then, the video display device 100 displays an object representing real-time audience rating information (S1360).

The network interface unit 730 of the server 500 may transmit the generated real time rating information and the like to at least one of the plurality of video display devices. Preferably, the generated real time rating information is transmitted to all the image display apparatuses that have transmitted the image including the broadcast information or the broadcast information.

The video display apparatus 100 receives real-time viewership information and the like via the network interface unit 135 and transmits the same to the control unit 170.

The controller 170 of the video display device 100 controls the display 180 to display an object representing real-time audience rating information using the received real-time rating information or the like. At this time, the object representing the real-time audience rating information can be superimposed on the broadcast image.

At this time, the objects representing the real-time viewership information can be sorted and displayed on a program-by-program or channel-by-real-time basis according to the real-time viewership.

In this manner, even when a broadcast signal is received through a set-top box or the like, audience rating information is generated and displayed by using broadcast information or an image included in the broadcast signal, What the channel is, and so on.

Meanwhile, in parallel with the above description, when a broadcast signal is received through the broadcast receiver 105 rather than the set-top box 250, the image display apparatus 100 displays an image including the broadcast information or broadcast information And transmit it to the server 500.

In addition, since the audience rating information can be generated and displayed even when a broadcast signal is received through a set-top box or the like as well as by watching a broadcast signal received through the broadcast receiver 105, the user can grasp a more accurate audience rating .

In step 1450, steps S1450 and S1350 correspond to step S1550 in FIG. 15, and step 1360 in FIG. 15 corresponds to step 1560 in FIG. 15 .

The control unit 170 of the video display device 100 generates an object 1665 indicating real-time audience rating information by using the real-time viewership information 1655 from the server 500 and displays the object 1665 on the display 180 As shown in Fig.

In the drawing, it is exemplified that broadcast information 1620 indicating channel information ('MBS HD') or program information ('infinite challenge') is displayed together.

Accordingly, the user can easily grasp the real-time viewership information. In addition, it is possible to search or view another broadcast channel or another broadcast program according to the audience rating, thereby making it possible to increase the usability of the user.

Meanwhile, the video display device 100 may determine whether the input broadcast signal is a real-time broadcast signal.

For example, the image display apparatus 100 may receive a real-time broadcast image 1640 received through a network, as shown in FIG. 16C. Accordingly, the image display apparatus 100 may compare the real-time broadcast image 1640 received through the network with the image 1625 received from the set-top box 250 to determine whether or not to broadcast in real time.

In this case, the image display apparatus 100 can determine the image 1625 received from the set-top box 250 as a real-time broadcast image, and extract real-time broadcast information from the real-time broadcast image based on the image.

As described above, when the same text, the same graphic or the like is displayed for a predetermined time in a specific area of a real-time broadcast image, for example, an edge area, the video display device 100 displays the broadcast information It is determined that the region is included, and the region can be extracted.

Then, the video display device 100 can extract real-time channel information ('MBS HD') or program information ('infinite challenge') based on the area. Then, the video display device 100 can transmit the real-time broadcast information to the server 500. [ At this time, when the real time broadcast information is transmitted, the video display device 100 may add a tag 'live' to the information.

On the other hand, the video display device 100 can extract broadcast information using the above-described method even when it is not a real-time broadcast image. Then, the video display apparatus 100 can transmit the broadcast information to be re-broadcasted to the server 500, not the live broadcast. At this time, when the re-broadcast information is transmitted, a tag 'record' may be added to the information.

The image display apparatus, the server and the operation method thereof according to the present invention are not limited to the configurations and the methods of the embodiments described above, but the embodiments are not limited thereto, Or some of them may be selectively combined.

Meanwhile, the method of operating the video display device or the method of operating the server of the present invention can be implemented as a code that can be read by a processor in a video-display device or a recording medium readable by a processor included in the server. The processor-readable recording medium includes all kinds of recording apparatuses in which data that can be read by the processor is stored. Examples of the recording medium that can be read by the processor include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and may also be implemented in the form of a carrier wave such as transmission over the Internet . In addition, the processor-readable recording medium may be distributed over network-connected computer systems so that code readable by the processor in a distributed fashion can be stored and executed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the present invention.
