For example, among a plurality of channels 2133, 2134, ... included in the second channel category 2132,'channel 2'2134 is selected, and each program 2137, in the program setting item 2135, is selected. 2138, ...) can be set to collect contact information and related information, and for'Channel 2'(2134) in the time setting item (2136), a time zone (2139) to collect contact information and related information can be set. have.

The user may select the communication link database data item 2200 to search data stored in the communication link database.

Referring to FIG. 17, data stored in the communication link database are classified according to a predetermined standard set by a manufacturer or a user, and data may be searched while following a hierarchical menu.

The communication link database data item 2200 includes data corresponding to contact information extracted from a program currently being watched, data corresponding to the most extracted contact information, data corresponding to the most recently extracted contact information, in a specific channel. It may include at least one of collected data and data corresponding to contact information that satisfies a user setting criterion.

In addition, the communication link database data item 2200 categorizes the collected data into various categories, such as the contact information 2211 viewed most by the user, the contact information 2212 viewed most recently, and data collected from a specific channel ( 2213) can include category items for viewing frequently used items.

Meanwhile, when the user selects the most recently viewed contact information 2212 and then selects any one of the plurality of channels 2214 and 2215, corresponding data 2219 may be displayed.

Thereafter, when receiving a selection input for any one of the displayed data, the controller 170 may control to execute a corresponding function according to the type of the selected contact information.

For example, if you select an e-mail address, you can execute an e-mail function that can send an e-mail to the selected e-mail address to switch to the e-mail creation screen, and if you select a phone number, you can perform a text message or phone connection function. Alternatively, if you select a predetermined web page address, you can access the corresponding web page.

The video display device is often used by a plurality of users. Therefore, it is more preferable that the communication link database can also be set for each user, and classified and managed.

Referring to FIG. 18, data may be managed for each of the first user 2220 and the second user 2230, and predetermined classification criteria 2231, 2232, 2233, and channel criteria 2234 for each user (2220, 2230). 2235, 2236) can be applied to easily search the sorted data.

Meanwhile, face information of a user may be acquired through a camera (not shown) provided in the image display device or a camera connected to the external device interface unit 130, and the user may be identified according to the acquired face information.

In this case, among the data stored in the communication link database, selected data based on the identified user may be displayed.

According to the present invention, it is possible to collect, store, and utilize various kinds of contact information provided by broadcasting, and user convenience is increased.

The image display device and its operation method according to the present invention are not limited to the configuration and method of the embodiments described as described above, but the embodiments are all or part of each embodiment so that various modifications can be made. May be configured by selectively combining.

Meanwhile, the method of operating an image display device of the present invention can be implemented as a code that can be read by a processor on a recording medium that can be read by a processor provided in the image display device. The processor-readable recording medium includes all types of recording devices that store data that can be read by the processor. Examples of recording media that can be read by the processor include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, etc., and also include those implemented in the form of carrier waves such as transmission through the Internet. . In addition, the recording medium that can be read by the processor is distributed over a computer system connected through a network, so that code that can be read by the processor can be stored and executed in a distributed manner.

In addition, although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and the technical field to which the present invention belongs without departing from the gist of the present invention claimed in the claims. In addition, various modifications are possible by those of ordinary skill in the art, and these modifications should not be individually understood from the technical spirit or prospect of the present invention.
