Meanwhile, the storage unit 140 may further store channel number information (channel 20) in the form of a channel map 1344.

FIG. 13E illustrates that the sixth broadcast signal Sf of the channel 23 is received by the video display device 100. FIG. The display 180 of the image display apparatus 100 may display the sixth broadcast image 1337 for the received sixth broadcast signal Sf. At this time, since the channel 23 is an analog broadcast signal, the storage unit 140 can store the frame image 1357 of the broadcast image. On the other hand, the storage unit 140 may further store channel number information (channel 23) in the form of a channel map 1347.

Next, when the channel search is terminated, the image display apparatus 100 determines whether a channel name image exists in the stored broadcast image. If it exists, the corresponding image is extracted, and the channel name of the corresponding channel is confirmed based on the extracted image. Then, a channel map can be generated using the channel number information and the channel name information.

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

Specifically, the control unit 170 determines whether an image representing a channel name exists in the broadcast image stored in the storage unit 140.

14A illustrates confirming the channel name through logo detection indicating the channel name in the image 1355 corresponding to the channel 21, which is stored in the storage unit 140. FIG.

The control unit 170 may call the broadcast image 1355 corresponding to the channel 21 to perform logo detection. Since the logo indicating the channel name is displayed at the upper right corner, the lower right corner, or the upper left corner of the broadcast image 1355, the control unit 170 extracts the corresponding region and stores the logo or text of the extracted region in the stored channel name Information, and find the corresponding channel name, and confirm the channel name.

14A, the control unit 170 extracts the logo 1412 displayed on the upper right side of the broadcast image 1355, thereby confirming the channel name 1414 (tvN).

14B, the identified channel name 1414 (tvN) may be stored in the storage unit 140 in the form of a channel map 1440 together with the channel number CH21.

Next, FIG. 14B illustrates confirming the channel name, through the logo detection indicating the channel name in the image 1355 corresponding to the channel 23, stored in the storage unit 140. FIG.

The control unit 170 may call the broadcast image 1357 corresponding to the channel 23 to perform logo detection.

14B, the controller 170 extracts the logo 1422 displayed on the upper right side of the broadcast image 1357, thereby confirming the channel name 1424 (New Y).

14B, the identified channel name 1424 (New Y) may be stored in the storage unit 140 in the form of a channel map 1442 together with the channel number CH 23.

On the other hand, when there is no image representing the channel name in the broadcast image stored in the storage unit 140, the image display apparatus 100 transmits the channel map, that is, the confirmed channel number information and the channel name information Can be transmitted.

For example, the control unit 170 can control the server 500 to transmit the generated channel map 1442 through the network interface unit 135, as shown in FIG. 14C.

The channel map 1442 of FIG. 14C includes channel names for the digital broadcast channels 9 and 11, and includes the channel names for the broadcast channels 21 and 23 including the channel names of the analog broadcast channels, Of the predetermined broadcast channels 20 and 22 do not include a channel name.

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 100, in particular. Next, the server 500 selects the corresponding channel map using the received channel number information and channel name information. Then, the server 500 can transmit the channel map information for the selected channel map to the video display device 100.

For example, the server 500 can directly transmit the selected channel map 1444 to the video display device 100 via the network interface unit 135 as shown in FIG. 14D. Alternatively, it is also possible to transmit only the channel name information (KBC, SBC) for the broadcast channels 20 and 22 that do not include the channel name in the channel map 1442 of FIG. 14C.

Accordingly, the controller 170 of the video display device 100 can complete the unfinished channel map using the received channel map information.

That is, when the selected channel map 1444 is directly received in the video display device 100 as shown in FIG. 14D, the received channel map 1444 can be replaced with the channel map being generated. That is, the channel map being generated can be updated to the received channel map 1444.

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 1444 is received, Map 1444. < / 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, when the channel name is confirmed through the channel map, it is possible to connect to the server 500 and receive program information such as the program name of the channel.
