To control the signal separation unit 220 and the decoder. At this time, when the user transmits a capture command, the remote control receiver 285 transmits the received command to the control unit 250, and the control unit 250 receives the command and the capture unit 270 captures the decoded broadcast screen and then enters together. Control to store in the storage unit 260 along with the additional information and service information.

As such, the broadcast screen, the broadcast information, and the broadcast service stored in the storage unit 260 are classified and managed for each user, and the control unit 270 receives a command through the remote controller 250 when the user requests a capture list (S330). A list of captured broadcasts is provided along with an icon representing each of the provided broadcast services (S340). For example, if a shopping service is provided by one of the captured broadcasts, the list displays a shopping icon on the captured broadcast item so that the user can intuitively know that the captured broadcast is a shopping service. do. Thereafter, when the user selects a specific item from the captured broadcast list, the remote controller 285 receives a user input (S350), notifies the control unit 250 of the selection signal, and the controller 250 determines the selected item. Information about the selected item is transmitted to a content provider (CP).

The controller 250 receives detailed information on the broadcast of the selected item and the service provided by the CP from the content provider (CP) through the network transmitter / receiver 240 and provides the user with the content. The CP can provide broadcast detail information and services in an HTML format, and through the network transmission / reception unit 240, the control unit 250 receives broadcast details and services in HTML format and configures them in a Web page format to the user. The detailed information and the service screen may be provided (S360). In this case, the controller 250 may also provide information about the search result of searching for information about the captured scene on the Internet as additional information in addition to the content provider.

The captured broadcast screen can be configured as a web page type service screen by combining with the broadcast detail information and service information in HTML format provided from CP together, thereby providing the user with selectable items in the captured broadcast screen. By selecting it, you can get detailed information about the item or go shopping.

In more detail, the control unit 250 combines the broadcast screen captured by the capture unit 270 with the service received through the network transmitter / receiver 240 to display a selectable item item on a captured broadcast screen as a text or directly display the screen. You can configure the items on the selectable. In the screen configured as described above, the user selects a desired service item, and the controller 250 receives the item selection command through the remote controller 285 (S370) and provides detailed information and services connected to the selected item (S380).

Up to now, the method of providing the multimedia content list and the sublist based on the operation of the controller 250 has been described with reference to FIG. 3.

Hereinafter, the screen configuration of the multimedia content list and the sublist will be described in more detail with reference to FIG. 4.
