Abstract

An image display apparatus, a server, and methods for operating the same are disclosed. The method for operating an image display apparatus includes entering channel scan mode, receiving a broadcast signal of a detected broadcast channel in the channel scan mode, extracting, in the presence of an image representing a channel name in a broadcast image of the broadcast signal, the image representing a channel name from the broadcast image, determining channel number information and channel name information about the broadcast channel based on the extracted image, and storing the channel number information and the channel name information about the broadcast channel in a channel map.

Claims

1. A method for operating an image display apparatus, comprising:

entering channel scan mode;

receiving a broadcast signal of a detected broadcast channel in the channel scan mode;

extracting, in the presence of an image representing a channel name in a broadcast image of the broadcast signal, the image representing a channel name from the broadcast image;

determining channel number information and channel name information about the broadcast channel based on the extracted image;

storing the channel number information and the channel name information about the broadcast channel in a channel map; and

displaying a channel map object corresponding to the channel map.

2. The method according to claim 1, in the absence of the image representing a channel name in the broadcast image of the broadcast signal, further comprising:

transmitting the channel number information and the channel name information to a server;

receiving channel map information from the server; and

updating the channel map using the received channel map information.

3. The method according to claim 1, further comprising storing the broadcast image of the broadcast signal, in the absence of the channel number information and the channel name information are not included in the broadcast signal of the detected broadcast channel,

wherein the reception of a broadcast signal and the storing of the broadcast image are repeated, while switching from one broadcast channel to another until channel scanning is completed in the channel scan mode.

4. The method according to claim 1, further comprising storing the broadcast image of the broadcast signal, in the absence of the channel number information and the channel name information are not included in the broadcast signal of the detected broadcast channel,

wherein upon completion of channel scanning in the channel scan mode, the image extraction is performed.

5. The method according to claim 1, further comprising:

determining whether the channel number information and the channel name information are included in the broadcast signal of the detected broadcast channel; and

storing the channel number information and the channel name information about the broadcast channel, if the channel number information and the channel name information are included in the broadcast signal of the detected broadcast channel.

6. The method according to claim 1, further comprising transmitting location information or network information about the image display apparatus to a server.

7. The method according to claim 2, further comprising receiving information about a broadcasting service type received from a broadcasting service provider from the server, in addition to the channel map information.

8. The method according to claim 1, wherein the determination of channel name information comprises determining a channel name of the broadcast channel by comparing the extracted image with a logo image representing a channel name pre-stored or received through a network.

9. The method according to claim 1, further comprising repeating the reception of a broadcast signal to the storing of the channel number information and the channel name information in a channel map, while switching from one broadcast channel to another until channel scanning is completed in the channel scan mode.

10. The method according to claim 1, further comprising determining whether the channel number information and the channel name information are included in the broadcast signal of the detected broadcast channel,

wherein the image extraction is performed in the absence of the channel number information and the channel name information in the broadcast signal of the detected broadcast channel.

11. An image display apparatus comprising:

a broadcasting receiver to receive a broadcast signal of a detected broadcast channel in channel scan mode;

a controller to extract, in the presence of an image representing a channel name in a broadcast image of the broadcast signal, the image representing a channel name from the broadcast image, and to determine channel number information and channel name information about the broadcast channel based on the extracted image;

a memory to store the channel number information and the channel name information about the broadcast channel in a channel map; and

a display to display a channel map object corresponding to the channel map.

12. The apparatus according to claim 11, further comprising a network interface to, in the absence of the image representing a channel name in the broadcast image of the broadcast signal, transmit the channel number information and the channel name information to a server, and to receive channel map information from the server,

wherein the controller updates the channel map using the received channel map information.

13. The image display apparatus according to claim 11, wherein in the absence of the channel number information and the channel name information are not included in the broadcast signal of the detected broadcast channel, the memory stores the broadcast image of the broadcast signal, and the controller repeats the broadcast signal reception and the broadcast image storing, while switching from one broadcast channel to another until channel scanning is completed in the channel scan mode.

14. The image display apparatus according to claim 11, wherein in the absence of the channel number information and the channel name information are not included in the broadcast signal of the detected broadcast channel, the memory stores the broadcast image of the broadcast signal, and upon completion of channel scanning in the channel scan mode, the controller performs the image extraction.

15. The image display apparatus according to claim 11, wherein if the channel number information and the channel name information are included in the broadcast signal of the detected broadcast channel, the memory stores the channel number information and the channel name information about the broadcast channel.
