6 (c) illustrates that the information 640 corresponding to the title ("KOSPI Index 1600 line collapse") 630 shown in Fig. 6 (b) is displayed.

As described above, the title is displayed and the information corresponding to the title is displayed on the display 180, so that the user can easily acquire the desired information. In addition, the title or information is displayed on the display 180 together with the broadcast image or the external input image, so that the user can simultaneously view the image and obtain desired information.

On the other hand, FIG. 8 exemplifies switching the title and information to be displayed together as a separate layer of the display together with the broadcast image and the title being displayed together.

That is, as shown in FIG. 8 (a), the title 830 in the web page connected to the broadcast video 820 is displayed together with the title 830 as well as the title 830 Information 840 can be displayed in different layers, i.e., in different areas. This conversion can be performed by the user's input. On the other hand, it is also possible to switch from Fig. 8 (b) to Fig. 8 (a).

Thus, by displaying the title and information of the connected web page together, the user can easily and quickly acquire desired information.

Next, it is determined whether the size of the displayed image varies according to user input (S430). If the size of the image is variable, it is determined whether the image and the title are displayed together (S435). When the size of the image is variable and the image and the title are displayed together, the size of the title or the number of titles is varied and displayed (S440).

FIG. 9 illustrates that the number of displayed titles is varied when the size of an image is variable while a title of a web page connected to the broadcast image is displayed.

9A shows that there is an input of a user to reduce the size of the image 920 in a state where any one of the web pages 930 connected to the broadcast image 920 is displayed.

Fig. 9 (b) shows the reduced broadcast image 925 and thus a relatively increased number of titles 935. Fig. In the drawing, one title 930 is displayed, and four titles 935 are displayed at a time in accordance with the image reduction. In addition to changing the number of titles, the title size can also be changed.

On the other hand, the variable of the image size can be performed according to the input of the user.

Conversely, when the number of titles of the connected web pages is large, it is possible to reduce the size of the displayed image and greatly change the size of the displayed image when the number of titles is small.

On the other hand, if the size of the image is variable, it is determined whether the image and the information are displayed together (S445). When the size of the image is variable and the image and information are displayed together, the amount of information is variable and displayed (S450).

10 illustrates that the amount of displayed information is variable when the size of the image is varied in a state in which information corresponding to a title of a web page connected to the broadcast image is displayed.

10A shows that there is an input of a user to reduce the size of the image 1020 while information 1040 corresponding to the title of the web page connected to the broadcast image 1020 is displayed.

10 (b) shows a reduced broadcast image 1025 and, accordingly, an increased amount of information 1045. FIG. In the figure, two lines of positive information 1040 are displayed, and four lines of positive information 1045 are displayed at once in accordance with the image reduction. It is also possible to change the display size of the displayed information in addition to changing the amount of information.

On the other hand, the variable of the image size can be performed according to the input of the user.

Conversely, when the amount of information corresponding to the title of the connected web page is large, the size of the displayed image is reduced, and when the amount of information corresponding to the title is small, It is also possible to do.

On the other hand, it is determined whether there is a web page edit input after step 425 (S425), and if there is the corresponding input, the web page edit menu is entered (S460). Then, the web page is edited (S465).

As shown in FIG. 12 (a), when a title 1230 of a web page connected to the broadcast image 1220 is displayed, the controller 170 can determine whether or not there is a web page edit input.

When there is an edit input of the web page by the user, the control unit 170 controls the web page menu 1250 to be displayed as shown in Fig. 12 (b). In the menu 1250, Accordingly, a predetermined web page can be selected, added, deleted, or edited.

On the other hand, the menu 1250 can show that a plurality of web pages (three web pages in the drawing) are stored in advance. Meanwhile, the menu 1250 may be displayed in a pop-up form while the broadcast image 2120 is displayed.

If it is determined that the connected web page has not been stored yet (S470), an object indicating whether to store the connected web page is displayed (S475). In accordance with the input of the user, the connected web page is stored (S480).

11A, when the title 1130 of the web page connected to the broadcast image 1120 is displayed, the control unit 170 determines whether the connected web page is a web page previously stored in the storage unit 140 Can be determined.

At this time, if the stored web page is not the stored web page, the control unit 170 controls to display an object 1150 indicating whether or not to store the connected web page as shown in Fig. 11 (b). In addition, the control unit 170 controls to store the connected web page according to the input of the user. Meanwhile, the object 1150 may be displayed in a pop-up form while the broadcast image 1120 is displayed.

On the other hand, after step 425 (S425), it is determined whether there is a title display setting input (S485), and a menu for setting the display time of the title is displayed (S490). Then, the set display time is stored according to the user's input (S495).

13A, when the title 1330 of the web page connected to the broadcast image 1320 is displayed, the control unit 170 determines whether or not there is a title display setting input for setting the display time of the title It can be judged.

At this time, when there is a title display setting input, the control unit 170 controls the display unit 1350 to display a menu 1350 for setting the title display time in the connected web page as shown in Fig. 13 (b). Also, the control unit 170 controls to store the display time of the title set according to the input of the user. Accordingly, the user can set the display time of the desired title according to taste or importance.
