In addition to receiving broadcast signals, the set-top box 250 may read media signals from a storage medium, such as an optical disk or a memory storage device, and process the media signals.

The video display device 100 may receive a broadcast signal through an antenna or may receive a broadcast signal from the set top box 250.

When the image display apparatus 100 receives the broadcast signal through the antenna, the image display apparatus 100 may receive the broadcast signal through the tuner unit 110 of FIG. 2. The broadcast signal received through the antenna may be a terrestrial digital broadcast signal, a terrestrial analog broadcast signal, a satellite digital broadcast signal, or the like.

When the image display device 100 receives the broadcast signal through the set top box 250, the image display device 100 may receive the broadcast signal through the external device interface unit 130 of FIG. 2. The broadcast signal received through the set-top box 250 may be a terrestrial digital broadcast signal, a terrestrial analog broadcast signal, a cable digital broadcast signal, a cable analog broadcast signal, a satellite digital broadcast signal, or an IPTV broadcast signal.

The image display apparatus 100 may generate a channel map including channel number information and channel name information according to an embodiment of the present invention.

In case of a terrestrial digital broadcasting signal received through an antenna, since it includes channel number information and channel name information, it can be used when generating a channel map.

Meanwhile, in the case of a terrestrial analog broadcast signal received through an antenna, channel number information is included but channel name information is not included, so it is not possible to know which channel name the channel number represents.

According to an exemplary embodiment of the present invention, when there is an image representing a channel name in a broadcast video, a channel name may be checked for a broadcast signal that does not include channel name information, such as a terrestrial analog broadcast signal. Specifically, the channel name can be confirmed by detecting a logo representing the channel name.

It is also possible to select a channel map corresponding to ..., 100n.

Alternatively, the channel map corresponding to each of the video display apparatuses 100a, 100b ..., 100n is not stored in the server 500, or the corresponding channel map cannot be matched or selected through another server. If a predetermined number of channel maps among the channel maps received by the image display apparatuses 100a, 100b, and 100n match, the corresponding channel map may be stored as a new channel map. At this time, it is preferable to complete and store a complete channel map by using the channel map received by each of the image display apparatuses 100a, 100b ..., 100n.

As described above, according to the exemplary embodiment of the present invention, in the channel search mode, the image display apparatus 100 receives a broadcast signal of the found broadcast channel and extracts the corresponding image when there is an image representing the channel name in the broadcast video. By checking the channel name on the basis of the extracted image, it is possible to simply generate a channel map using the channel number information and the channel name information. Accordingly, the usability of the user can be increased.

On the other hand, if there is no image indicating a channel name in the broadcast video, the video display device 100 transmits the confirmed channel number information and the channel name information to the server 500, and receives the channel map information from the server 500. By updating the channel map using the received channel map information, it is possible to complete a channel map including channel name information for all channels.

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.

Here, the format of the 3D video signal is a side-by-side format in which the left-eye image signal L and the right-eye image signal R are arranged in left and right directions, a top- An interlaced format in which the left and right eye image signals and the right eye image signal are mixed line by line, a checker box for mixing the left eye image signal and the right eye image signal box by box, Format, 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. [

In addition, the processor 330 may perform data transfer control with the network interface unit 135 or the external device interface unit 130.

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 generator 340 generates an OSD signal according to a user input or 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 the pointing signal processor, and the OSD generator 240 may include such a pointing signal processor (not shown). Of course, a pointing signal processing unit (not shown) may be provided separately from the OSD generating unit 240.

The mixer 345 may mix the OSD signal generated by the OSD generator 340 and the decoded video signal processed by the image processor 320. 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. Then, the left eye glass of the 3D viewing apparatus (not shown) 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.

On the other hand, the formatter 360 can change the format of the 3D video signal. For example, it can be changed to any one of the various formats described above.

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. [

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.

In addition, the audio processing unit (not shown) in the control unit 170 can process a base, a treble, a volume control, and the like.

The data processing unit (not shown) in the control unit 170 can perform data processing of the demultiplexed data signal. For example, if the demultiplexed data signal is a coded data signal, it can be decoded. The encoded data signal may be EPG (Electronic Program Guide) information including broadcast information such as a start time and an end time of a broadcast program broadcasted on each channel.

4 shows that the signals from the OSD generating unit 340 and the image processing unit 320 are mixed in the mixer 345 and then 3D processed in the formatter 360. 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 converting unit 350 and the formatter 360 are not provided in the controller 170, and may be separately provided, or may be separately provided as one module.

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 device 200 moves away from or near the display 180, the up, down, left and right movements are not recognized, and only the front and back movements can be 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.

7 is an internal block diagram of the server of FIG.

7, the server 500 may include a network interface unit 730, a storage unit 740, and a processor 720.

The network interface unit 730 receives the channel number information and the channel name information (MBS, CBB, KBB, NCC, etc.) from at least one video display device, or receives each generated channel map information have.

The network interface unit 730 further receives program names (Oh! Lady, ABC news, DR. OZ, etc.) broadcasted from the at least one video display devices in addition to the broadcast channel names .

8 is a flowchart illustrating a method of operating an image display apparatus according to an embodiment of the present invention, FIG. 9 is a flowchart illustrating a method of operating a server according to an embodiment of the present invention, and FIGS. 10 to 16E are illustrated in FIG. 8. Or, it is a view referred to explain various examples of the operation method of FIG.

First, the image display apparatus 100 enters a channel search mode (S810). The channel search mode may enter automatically according to a user input. For example, the channel search mode may be an automatic channel search mode or a manual channel search mode.

11A illustrates that the automatic channel search mode is performed. As shown in the drawing, when the user enters the automatic channel search mode, an automatic channel search is performed, and an object 1120 representing the automatic channel search can be displayed as shown in the figure.

On the other hand, the object 1120 indicating the automatic channel search mode can be displayed together with the broadcast image 1110 of the channel 9 (CH 9) being viewed. The corresponding object 1120 can be displayed transparently so that the broadcast image 1110 of the channel being viewed can be seen.

On the other hand, the controller 170 of the video display device 100 controls the automatic channel search mode to be an automatic channel search mode by user input for entering the automatic channel search mode. That is, the control unit 105 controls the broadcast receiving unit 105 to change the channel of the inputted broadcast signal while searching for it.

Next, the video display device 100 receives a broadcast signal of the found broadcast channel (S815). In operation S820, it is determined whether channel number information or channel name information is included in the broadcast signal. If not included, the broadcast video in the broadcast signal is stored (S822). On the other hand, if included, the channel number information and the channel name information is stored (S823).

The video display device 100 receives a broadcast signal found through the broadcast receiving unit 105.

For example, when a broadcast signal is received through an antenna, the tuner 110 in the broadcast receiver 105 may sequentially receive broadcast images of a plurality of channels while changing a channel. The controller 170 may control the tuner 110 to change the channel. The broadcast signal received through the tuner 110 is input to the controller 170 via the demodulator 120.

Meanwhile, when a broadcast signal is received through the set top box 250, that is, when the broadcast signal is received through the external device interface unit 130, the controller 170 controls the broadcast image of a plurality of channels in the set top box 250. Can be controlled to be received. For example, a control signal for automatic channel searching may be transmitted to the set top box 250. Meanwhile, the broadcast signal received through the external device interface unit 130 is input to the controller 170.

The broadcast signal received by the controller 170 is demultiplexed by the demultiplexer 310. The controller 170 determines whether channel number information or channel name information is included in the data signal of the demultiplexed broadcast signal. For example, in the case of a digital broadcast signal of the ATSC standard, channel number information or channel name information may be included in the PSIP. As another example, in the case of a digital broadcast signal of the DVB standard, channel number information or channel name information may be included in the SI.

If the received broadcast signal is a digital broadcast signal received through an antenna, the controller 170 extracts channel number information or channel name information included in the broadcast signal. The extracted channel number information and channel name information are stored in the storage unit 140. At this time, it may be stored in the storage unit 140 as a channel map.

FIG. 11B illustrates that the first display signal Sa of the channel 9 is received by the video display device 100. The display 180 of the image display apparatus 100 may display the first broadcast image 1130 for the received first broadcast signal Sa. In this case, since the channel 9 is a digital broadcast signal, when the broadcast signal of the channel 9 is received through the antenna, as in the step 823 (S823), the storage unit 140 is in the form of a channel map 1141, and has a channel number. Information (channel 9) and channel name information (KBS 1) can be stored.

Meanwhile, when the received broadcast signal is a digital broadcast signal received through the set top box 250, the received broadcast signal may include channel number information or channel name information included in the broadcast signal. In this case, as described above, the controller 170 controls to extract the channel number information or the channel name information and store the channel number information or the channel name information in the storage unit 140 as a channel map form.

On the other hand, when the received broadcast signal is an analog broadcast signal, the channel number information is included in the broadcast signal, but the channel name information may not be included. In this case, the controller 170 may perform demultiplexing and image signal processing on the received broadcast signal and control to store the processed broadcast image. The stored broadcast image can be stored in the storage unit 140 as a still image. Meanwhile, the broadcast image to be stored is preferably stored together with the channel number information.

Meanwhile, when the received broadcast signal is a digital broadcast signal received through the set top box 250, the received broadcast signal may not include channel number information or channel name information included in the broadcast signal. The digital broadcast signal provided by the cable operator may not include channel number information or channel name information. In this case, step S822 is performed as if an analog broadcast signal is received. That is, the controller 170 may perform demultiplexing and image signal processing on the received broadcast signal and control to store the processed broadcast image.

11D illustrates that the third broadcast signal Sc of the channel 20 is received by the video display device 100. The display 180 of the image display apparatus 100 can display the third broadcast image 1134 with respect to the received third broadcast signal Sc. In this case, since the channel 20 is an analog broadcast signal, the storage unit 140 may store the frame image 1154 of the broadcast video as in step 822. Meanwhile, the storage unit 140 may further store channel number information (channel 20) in the form of a channel map 1144.

Next, the image display apparatus 100 determines whether the channel search is ended (S824), and if the channel search is not ended, searches for the next channel (S826). Subsequently, steps 815 to 824 (S824) are repeated with respect to the found broadcast channel signal.

FIG. 11C illustrates that the second broadcast signal Sb of the channel 11 is received by the video display device 100. The display 180 of the image display apparatus 100 may display the second broadcast image 1132 for the received second broadcast signal Sb. In this case, since the channel 11 is a digital broadcast signal, when the broadcast signal of the channel 11 is received through the antenna, the storage unit 140 stores the channel number 1142 in the form of the channel map 1142 as in step 823 (S823) Information (channel 11), and channel name information (MBC).

11E illustrates that the sixth broadcast signal Sf of the channel 23 is received by the video display device 100. The display 180 of the image display apparatus 100 can display the sixth broadcast image 1137 for the received sixth broadcast signal Sf. In this case, since the channel 23 is an analog broadcast signal, the storage unit 140 may store the frame image 1157 of the broadcast video as in step 822. Meanwhile, the storage unit 140 may further store channel number information (channel 23) in the form of a channel map 1147.

Next, when the channel search is terminated, the image display apparatus 100 determines whether a channel name image exists in the stored broadcast image (S840). If present, the corresponding image is extracted (S845), and the channel name of the corresponding channel is checked based on the extracted image (S850). Then, a channel map is generated using the channel number information and the channel name information (S855).

In the channel search mode, the controller 170 generates a channel map by using the pre-stored broadcast image when all the channel searches are completed.

In detail, the controller 170 determines whether an image representing a channel name exists in the broadcast video stored in the storage 140.

FIG. 12A illustrates confirming the channel name through logo detection indicating the channel name in the image 1155 corresponding to the channel 21 stored in the storage 140.

The controller 170 may call the broadcast image 1155 corresponding to the channel 21 to perform logo detection. In general, a logo indicating a channel name is displayed on the upper right, lower right, or upper left of the broadcast image 1155, so that the controller 170 extracts the corresponding area and stores the logo or text of the extracted area in advance. Compared with the information, the corresponding channel name can be found and the channel name can be confirmed.

As illustrated in (a) of FIG. 12A, the controller 170 may extract the logo 1212 displayed on the upper right end of the broadcast image 1155, and thereby check the channel name 1214 (tvN).

As shown in (b) of FIG. 12A, the identified channel names 1214 and tvN may be stored in the storage unit 140 as a channel map 1240 together with the channel number CH 21.

Next, FIG. 12B illustrates confirming the channel name through logo detection indicating the channel name in the image 1155 corresponding to the channel 23 stored in the storage 140.

The controller 170 may call the broadcast image 1153 corresponding to the channel 23 to perform logo detection.

As illustrated in (a) of FIG. 12B, the controller 170 may extract the logo 1222 displayed on the upper right end of the broadcast image 1153, and thereby check the channel name 1224 (New Y).

As shown in (b) of FIG. 12B, the identified channel name 1224 (New Y) may be stored in the storage unit 140 as a channel map 1242 together with the channel number CH 23.

On the other hand, if there is no image in operation 840 (S840), the video display device 100 transmits the channel number information and the channel name information confirmed to the server (S870). Meanwhile, step 870 (S870) of FIG. 8 corresponds to step 970 (S970) of FIG. 9 and step 1070 (S1070) of FIG.

If the image representing the channel name does not exist in the broadcast image, the controller 170 can not confirm the channel name for the channel, so that the controller 170 can control to transmit the confirmed channel number information and channel name information to the server 500 have.

For example, as illustrated in FIG. 12C, the controller 170 may control to transmit the channel map 1242 generated up to that time to the server 500 through the network interface 135.

The channel map 1242 of FIG. 12C includes channel names for digital broadcast channels 9 and 11, and includes analog channel names for broadcast channels 21 and 23 including channel names among analog broadcast channels. Of the predetermined broadcast channels 20 and 22, the channel names are not included.

The server 500 receives the channel number information and channel name information confirmed from the video display device 100 (S970). The network interface unit 735 in the server 500 receives the channel number information and the channel name information confirmed from the video display device. Alternatively, the generated channel map can be received. On the other hand, step 970 (S970) of FIG. 9 corresponds to step 870 (S870) of FIG. 8 and step 1070 (S1070) of FIG.

Next, the server 500 selects the corresponding channel map using the received channel number information and channel name information (S973). The processor 720 of the server 500 selects a channel map corresponding to the channel map received from the video display device 100 using a plurality of channel maps stored in the storage unit 740. [ On the other hand, step 973 (S973) of FIG. 9 corresponds to step 1073 (S1073) of FIG.

For example, some of the channels 9, 11, 21, and 23 of the channel map 1242 of FIG. 12C include a channel name, and thus, the channel numbers 9, 11, 21, 23, and the channel names KBS1, MBC, tvN, NewY) can be used to select the corresponding completed channel map.

Next, the server 500 transmits the channel map information for the selected channel map to the video display device 100 (S975). The network interface unit 735 in the server 500 transmits channel map information on the selected channel map to the video display device 100. On the other hand, step 975 (S975) of FIG. 9 corresponds to step 875 (S875) of FIG. 8 and step 1075 (S1075) of FIG.

For example, as illustrated in FIG. 12D, the server 500 may directly transmit the selected channel map 1244 to the image display device 1244 through the network interface 135. Alternatively, channel name information (KBC, SBC) for the broadcast channels 20 and 22 that do not include the channel name in the channel map 1242 of FIG. 12C may be transmitted.

Next, the image display apparatus 100 updates the channel map using the received channel map information (S880). Meanwhile, step 880 (S880) of FIG. 8 corresponds to step 880 (880) of FIG.

The channel map information received through the network interface unit 135 of the video display device 100 may be input to the control unit 170. The controller 170 can complete the unfinished channel map using the received channel map information.

As shown in FIG. 12D, when the selected channel map 1244 is received by the image display apparatus 100 as it is, the received channel map 1244 may be replaced with a channel map being generated. That is, the channel map being generated can be updated to the received channel map 1244.

Alternatively, when the channel name information (KBC, SBC) for the broadcast channels 20 and 22 that do not include the channel name among the selected channel map 1244 is received, Map 1244. < / RTI >

Accordingly, the channel names (KBC, SBC) for the channels 20 and 22 that can not be confirmed by the image display apparatus 100 can be easily recognized.

On the other hand, after step 855 or after step 880 or step 880, step S860 of determining whether a channel map is completed may be performed. When the channel map is not completed, step 840 or less Will be performed repeatedly.

FIG. 13A illustrates that the location information or network information S1 of the incomplete channel map 134 or the image display apparatus 100 is transmitted from the image display apparatus 100 to the server 500.

The control unit 170 of the video display device 100 can control to transmit the unfinished channel map 134 or the location information of the video display device 100 or the network information S1 through the network interface unit 135 have.

Here, the location information or the network information S1 may be a concept including the IP address of the image display apparatus 100, area information, and the like. Through this information, the server 500 can easily identify the broadcast service provider to which the video display device 100 is subscribed.

Meanwhile, the channel map 1340 of FIG. 13A illustrates that the channel names (OCN ...) for the channel numbers 25, 26, 32, and 29 are confirmed, but the channel names for the channel 52 are not identified.

13B illustrates an example of channel map selection at server 500.

As shown in (a) of FIG. 13B, the processor 720 of the server 500 may receive the location information or the network information of the unfinished channel map 1340 or the image display apparatus 100 received through the network interface unit 735. (S1) can be used.

That is, the plurality of channel maps stored in the storage unit 740 as shown in (b) of FIG. 13B by using the location information or the network information S1 of the incomplete channel map 134 or the image display apparatus 100. 1350 may be filtered.

For example, when the location information or the network information S1 indicates a specific region (for example, Seocho-gu), the processor 720 of the server 500 stores the storage unit (c) as shown in FIG. 13B (c). Only a broadcast service provider list 1360 that provides a broadcast service in a specific region of the broadcast service information list 1350 including a plurality of broadcast service providers stored in 740 may be searched for.

FIG. 13B (c) illustrates that three broadcast service providers 1362, 1364, and 1366 are extracted.

The processor 720 of the server 500 matches the channel maps provided by the three broadcast service providers 1362, 1364, and 1366 using the unfinished channel map 1340 received. Then, the processor 720 of the server 500 selects a corresponding channel map.

FIG. 13C illustrates a comparison of channel maps 1372, 1374, and 1376 corresponding to three broadcast service providers using the received incomplete channel map 1340. Referring to the drawing, it can be seen that the channel map corresponding to the incomplete channel map 1340 corresponds to the first channel map 1372. Thus, the channel name (YSS) for the channel 52 can be known.

Next, the processor 720 of the server 500 can control to transmit the selected channel map 1372 to the video display device 100. [

13D illustrates that the selected channel map information 1372 is transmitted from the server 500. At this time, the channel map information may further include broadcast service provider information 1343 for providing a broadcast service to the video display device 100, in addition to channel number information and channel name information. The broadcast service provider information 1343 can be transmitted separately from the channel map information 1372.

Meanwhile, the channel map information transmitted from the server 500 to the video display device 100 may include channel number information, channel name information, and broadcast service type information provided from a broadcast service provider.

FIG. 13E illustrates channel maps 1382, 1384, and 1386 according to broadcast service type information provided by the same broadcast service provider. It can be seen that each channel map is classified into a stationary channel map 1382, a basic channel map 1384, an advanced channel map 1386, and the like, depending on the service type.

The processor 720 of the server 500 can compare the channel maps 1382, 1384, and 1386 according to the broadcast service type information using the incomplete channel map received from the video display device 100. [ Then, the corresponding channel map 1386 can be selected.

FIG. 13F illustrates that the selected channel map information 1386 is transmitted from the server 500. The channel map information at this time may further include a broadcast service type information (advanced type) 1344 for providing a broadcast service to the video display device 100, in addition to the channel number information and the channel name information. The broadcast service type information (advanced type) 1344 can be transmitted separately from the channel map information 1386. [

14A illustrates that the server 500 receives corresponding unfinished channel map information 1440a, 1440b, ..., 1440c from the plurality of image display devices 100a, 100b, ..., 100n, respectively. do.

The server 500 may include the incomplete channel map information 1440a, 1440b, 1440c received from the plurality of image display apparatuses 100a, 100b, ..., 100n, and the channels stored in the server 500. The map information 1450 may be compared to select a corresponding channel map.

In the drawing, the channel map information 1440a received from the first image display apparatus 100a among the plurality of image display apparatuses 100a, 100b,..., And 100n and the channel map information stored in the server 500 ( Comparing 1450, selecting a corresponding channel map is illustrated.

The server 500 may transmit the selected channel map information to each of the image display apparatuses 100a, 100b.

14B illustrates that the server 500 receives the same incomplete channel map information 1440a from the plurality of image display devices 100a, 100b, ..., 100n.

The server 500 compares the incomplete channel map information 1440a received from the plurality of image display apparatuses 100a, 100b,..., 100n with the channel map information 1450 stored in the server 500. Thus, the corresponding channel map can be selected.

In this case, there may be a case in which there is no channel map corresponding to the incomplete channel map information 1440a among the channel map information 1450 stored in the server 500.

In this case, the server 500 may store the channel map as a new channel map when a predetermined number of channel maps among the channel maps received by the image display apparatuses 100a, 100b. . At this time, it is preferable to complete and store a complete channel map by using the channel map received by each of the image display apparatuses 100a, 100b ..., 100n.

14C illustrates that in the server 500, the channel map information 1440a is added to the existing channel map information 1450, so that the updated channel map information 1460 is stored. The channel map information 1440a of FIG. 14C is preferably complete channel map information filled with all channel names.

On the other hand, by data exchange between the video display device 100 and the server 500, in particular, by channel map information exchange, the video display device 100 may store the completed channel map.

In the case of a user input or a channel map completion, the video display device 100 may display an object 1520 representing a channel map on the display 180 as shown in FIG. 15. In this case, the object 1520 may be displayed together with the broadcast image 1510. Accordingly, the user can easily grasp the channel name corresponding to the channel number.

 On the other hand, the video display device can also display real-time viewership information by exchanging data with the server.

FIG. 16A illustrates that broadcast information 1630 from the video display device 100 or an image 1625 including broadcast information is transmitted to the server 500.

In the drawing, the broadcast information 1630 is also transmitted as an image, but, on the contrary, the broadcast information 1630 may be text-based data, not image data. For example, the broadcast information may be text data corresponding to 'MBS HD' or 'Infinite Challenge'.

Meanwhile, in the drawing, an image 1625 including broadcast information is illustrated as an entire broadcast video image. Alternatively, the image may include an image including only broadcast information. That is, reference numeral 1630 of the figure may be an image including broadcast information.

Next, FIG. 16B illustrates that the server 500 compares the real-time broadcast image 1640 received through the network with the image 1625 received from the video display device 100 to determine whether the real-time broadcast is performed. do.

The server 500 may receive real-time broadcast images 1640a, 1640b, 1640c, and 1640d through a network. Then, it may be stored in the storage unit 740.

Meanwhile, the processor 720 of the server 500 compares the received real-time broadcast images 1640a, 1640b, 1640c, and 1640d with the image 1625 received from the video display device 100 to determine whether they are the same. In the same case, it is determined that the image 1625 received from the video display device 100 is a real-time broadcast image.

To this end, the processor 720 of the server 500 may use an image pattern comparison algorithm.

In the drawing, the second real-time broadcast image 1640b and the image 1625 received from the image display apparatus 100 are identical among the received real-time broadcast images 1640a, 1640b, 1640c, and 1640d.

Next, FIG. 16C illustrates that the server 500 generates real-time viewership information.

In this case, the real-time viewer rating information includes broadcast information or broadcast image received from the set-top box 250 to the video display device 100 and broadcast information or broadcast image received from the broadcast receiver 105 to the video display device 100. Including all, it may be generated real-time viewership information.

In the figure, it is illustrated that real-time viewership information is generated according to the number of viewers.

Next, FIG. 16D illustrates that real-time viewership information 1655 from the server 500 is transmitted to the video display device 100.

 The network interface unit 135 of the image display apparatus 100 may receive real-time viewership information 1655 from the server 500.

Next, FIG. 16E illustrates that an object 1665 indicating real-time viewership information is displayed together with the broadcast image 1660 on the image display apparatus 100.

The controller 170 of the image display apparatus 100 generates an object 1665 representing the real-time viewership information by using the real-time viewership information 1655 from the server 500, and displays the object 1665. ) Can be displayed.

Meanwhile, in the drawing, broadcast information 1620 indicating channel information 'MBS HD' or program information ('Infinite Challenge') is also displayed.

Accordingly, the user can easily grasp the real-time viewership information. In addition, according to the viewer rating, it is possible to search or watch other broadcast channels or other broadcast programs, thereby increasing user convenience.

On the other hand, the video display device 100 may determine whether the input broadcast signal is a real time broadcast signal.

For example, as illustrated in FIG. 16B, the video display device 100 may receive a real time broadcast image 1640 received through a network. Accordingly, the image display apparatus 100 may compare the real-time broadcasting image 1640 received through the network with the image 1625 received from the set-top box 250 to determine whether the real-time broadcasting is performed.

In this case, the video display device 100 may 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.

As described above, when the same text, the same figure, the pattern, or the like is displayed in a specific area, for example, a corner area of the real-time broadcast video, for a predetermined time, the video display device 100 displays the broadcast information in the corresponding area. It may be determined as an area to be included and the corresponding area may be extracted.

The image display apparatus 100 may extract real-time channel information 'MBS HD' or program information ('Infinite Challenge') based on the corresponding area. The video display device 100 may transmit real time broadcast information to the server 500. In this case, when transmitting real-time broadcast information, the video display device 100 may add a tag 'live' to the corresponding information.

On the other hand, even when the video is not a real-time broadcast video, the video display device 100 may extract broadcast information using the above-described method. In addition, the video display device 100 may transmit the broadcast information re-broadcasted to the server 500 instead of live. In this case, when rebroadcast broadcast information is transmitted, a tag called 'record' may be added to the corresponding information.

Next, FIG. 16E illustrates that an object 1665 indicating real-time viewership information is displayed together with the broadcast image 1660 on the image display apparatus 100.

The controller 170 of the image display apparatus 100 generates an object 1665 representing the real-time viewership information by using the real-time viewership information 1655 from the server 500, and displays the object 1665. ) Can be displayed.

Meanwhile, in the drawing, broadcast information 1620 indicating channel information 'MBS HD' or program information ('Infinite Challenge') is also displayed.

Accordingly, the user can easily grasp the real-time viewership information. In addition, according to the viewer rating, it is possible to search or watch other broadcast channels or other broadcast programs, thereby increasing user convenience.

17 is a flowchart illustrating a method of operating an image display device according to another exemplary embodiment. FIGS. 18A to 18I are diagrams for describing various examples of the method of FIG. 17.

The operation method of FIG. 17 is similar to the operation method of FIG. 8, except that unlike FIG. 8, after completing the channel search, the channel map is generated while performing the channel search instead of generating the channel map. There is a difference in doing it. Therefore, the storing of the broadcast image (S822), the channel number and the channel name storing step (S823) of FIG. 8 may be omitted. Hereinafter, the difference will be described.

Since the seventeenth step S1710, the first seventeenth step S1715, and the first seventh step S1720 correspond to the eighth step S810, the eighth step S815, and the eighteenth step S820 of FIG. 8, respectively. , The description is omitted.

Meanwhile, steps 1740 through 1765 (S1740, S1745, S1750, and S1755) correspond to steps 840 through 865 (S840, S845, S850, and S855) of FIG. 8. However, steps 1740 to 1765 (S1740, S1745, S1750, and S1755) may be repeatedly performed at each channel search, not after the end of the channel search of FIG. 8.

Further, steps 1770 through 1780 (S1770, S1775, and S1780) correspond to steps 870 through 880 (S870, S875, and S880) of FIG. 8.

On the other hand, it is determined whether or not the end of the channel search (S1760), and if applicable, the next channel is searched (S1765). Then, steps 1715 and below are repeated again.

18A illustrates that an automatic channel search mode is performed. As shown in the drawing, when the user enters the automatic channel search mode, an automatic channel search is performed, and an object 1120 representing the automatic channel search can be displayed as shown in the figure.

18B illustrates that the first display signal Sa of the channel 9 is received by the video display device 100. The display 180 of the image display apparatus 100 may display the first broadcast image 1130 for the received first broadcast signal Sa. In this case, since the channel 9 is a digital broadcast signal, when the broadcast signal of the channel 9 is received through the antenna, the storage unit 140 is in the form of a channel map 1140 and has channel number information (channel 9) and channel name information. (KBS 1) can be saved.

18C illustrates that the video display device 100 receives the second broadcast signal Sb of the channel 11. The display 180 of the image display apparatus 100 may display the second broadcast image 1132 for the received second broadcast signal Sb. In this case, since the channel 11 is a digital broadcast signal, when the broadcast signal of the channel 11 is received through the antenna, the storage unit 140 has a channel map 1142 in the form of channel number information (channel 11) and channel name information. You can store more (MBC).

18D illustrates that the third broadcast signal Sc of the channel 20 is received by the video display device 100. The display 180 of the image display apparatus 100 can display the third broadcast image 1134 with respect to the received third broadcast signal Sc. At this time, when the channel 20 is an analog broadcast signal and an image representing the channel name does not exist in the broadcast video, the channel name for the corresponding channel cannot be confirmed. Accordingly, the storage 140 may store only the channel number information (channel 20) without the channel name information in the form of the channel map 1144.

In this case, the control unit 170 of the video display device 100 stores the channel number information (9, 11), the channel name information (KBS1, MBC) or the channel map information (1144) generated up to that time. 500).

On the other hand, the control unit 170 of the video display device 100 can determine the channel number information and the channel name information only when the number of the channel number information 9 and 11 and the channel name information KBS1 and MBC confirmed up to that time is equal to or greater than a predetermined number. Alternatively, it may be controlled to transmit the generated channel map information to the server 500. As shown in FIG. 18D, since the corresponding channel map cannot be selected by the server 500 based on such information, it may be preferable not to transmit the corresponding information to the server 500.

18E illustrates that the fourth broadcast signal Sd of the channel 21 is received by the video display device 100. The display 180 of the image display apparatus 100 may display a fourth broadcast image 1501 with respect to the received fourth broadcast signal Sd. At this time, if the channel 21 is an analog broadcast signal and an image representing the channel name exists in the broadcast video, the channel name can be confirmed by detecting a logo representing the channel name.

Accordingly, the controller 170 may extract the broadcast image 1155 corresponding to the channel 21 and perform logo detection. The controller 170 may extract the logo 1212 displayed on the upper right end of the broadcast image 1155 and check the channel name 1214 (tvN) through this. On the other hand, the identified channel name 1214 (tvN), along with the channel number (CH 21) can be stored in the storage unit 140 in the form of a channel map 1445.

18F illustrates that the fifth broadcast signal Se of the channel 22 is received by the video display device 100. The display 180 of the image display apparatus 100 may display a fifth broadcast image 1136 with respect to the received fifth broadcast signal Se. At this time, when the channel 22 is an analog broadcast signal and an image representing the channel name does not exist in the broadcast video, the channel name for the corresponding channel cannot be confirmed. Accordingly, the storage 140 may further store only the channel number information (channel 22) without the channel name information in the form of the channel map 1146.

18G illustrates that the sixth broadcast signal Sf of the channel 23 is received by the video display device 100. The display 180 of the image display apparatus 100 can display the sixth broadcast image 1137 for the received sixth broadcast signal Sf. At this time, when the channel 23 is an analog broadcast signal and an image representing the channel name exists in the broadcast video, the channel name can be confirmed by detecting a logo indicating the channel name.

Accordingly, the controller 170 may extract the broadcast image 1157 corresponding to the channel 23 and perform logo detection. The controller 170 may extract the logo 1222 displayed at the upper right end of the broadcast image 1157 and check the channel name 1224 (News Y) through the extracted logo 1222. The identified channel name 1224 (NewsY) may be stored in the storage unit 140 as a channel map 1447 together with the channel number CH 23.

18H illustrates that the channel map information 1147 generated up to that point is transmitted from the image display apparatus 100 to the server 500. Of course, it is also possible to transmit only the channel numbers (9, 11, 21, 23) and channel name information (KBS1, MBC, tvN, NewsYY) identified up to that time in the channel map.

On the other hand, the control unit 170 of the video display device 100, the channel number information, the channel name only when the number of the channel number information and the channel name information confirmed up to that time, for example, four or more as shown in the figure Information or channel map information generated up to that point may be controlled to be transmitted to the server 500.

On the other hand, the server 500 selects the corresponding completed channel map using the received channel map information 1147.

18I illustrates the transmission of the completed channel map information 1244 from the server 500 to the video display device 100. Accordingly, the video display device 100 can check the channel name of the specific channel number that could not be confirmed.

On the other hand, in the figure, although the completed channel map information 1244 is illustrated as being transmitted as it is, in contrast, it is also possible to transmit only the channel number information and channel name information that has not been confirmed. For example, it is also possible to transmit only the channel name KBC of channel 20 and the channel name SBC of channel 22.

Meanwhile, in addition, the real-time viewership information EH may be further transmitted from at least one of broadcast service type information provided from a broadcast service provider from the server 500 to the video display device 100. Accordingly, the usability of the user can be increased.
