When a user selects the Internet mode, the microcomputer 22 displays the video and audio information or the initial screen of the Internet site that is previously set and stored corresponding to the address of the Internet site previously stored in the memory 21 on the screen of a television (S31).
When the video information, the audio information, or the initial screen of the stored Internet site corresponding to the previously set Internet address is displayed on the screen of the television, the microcomputer 22 determines whether it is time to update the channels of the respective Internet sites (S32). The channels of the respective Internet sites refer to channels previously stored in the memory 21 with the address of a predetermined Internet site assigned to each channel (channel numbers in the Internet site search menu).
When the time to update the channels of the Internet sites has lapsed, the microcomputer 22 periodically updates the information of the Internet sites (the initial screen of the Internet sites) corresponding to the channels of the Internet sites (S33). That is, the user can see the recent information of the Internet site without downloading by displaying the recent information of the Internet site corresponding to the channel of the previously stored Internet site when the user selects the channel of the Internet site.
When the time to update the channels of the Internet sites has not lapsed, the microcomputer 22 determines whether the Internet channel guide key signal (or an Internet start signal) is input (S34). That is, when the user presses the Internet channel guide key (not shown) of the key input unit 30 or clicks the Internet channel guide icon (not shown) on the initial screen of the Internet site (S34), the microcomputer 22 displays the Internet site search menu (S35).

The channel number selected by the user and the title of the Internet site corresponding to the channel number selected by the user in the channel guide windows 72 and 73 are displayed to be different from the channel numbers that are not selected by the user and the titles of the Internet sites corresponding to the channel numbers that are not selected by the user in color and brightness and to have three-dimensional outlines. The channel number range designation window 75 sequentially displays channels such that each of predetermined numbers of channels such as channels 1 through 10, channels 11 through 20, and channels 21 through 30, etc. form a unit and displays the part corresponding to the channel range selected by the user to be different from other channel ranges in color and brightness and to have a three-dimensional outline.
The microcomputer 22 determines whether a key signal is input when a user inputs a predetermined key in the Internet site search menu (S36). The method for displaying the Internet site search menu when the key signal is input from the predetermined key will now be sequentially described.
When the user inputs a register key or a modification key in the registration/modification/deletion window 76 (S37, S38 and S39), the microcomputer 22 outputs a control signal including the video information stored in the memory 21 to an Internet site search menu generator 26.
The Internet site search menu generator 26 receives the control signal, generates a registration/modification window, and displays the registration/modification window on the screen of the television through the video processor 28 (S41). The registration/modification window will now be described in detail with reference to FIG. 8.
FIG. 8 shows a window for registering/modifying the Internet site according to the present invention.

When the user inputs the confirm key (S52), the microcomputer 22 deletes the Internet site information of the corresponding channel from the memory 21 and stops displaying the warning message (S54). When the user inputs the cancellation key (S53), the microcomputer 22 stops displaying the cancellation warning message (S55) and the process returns to the step of determining whether the key signal is input (S36). 
When the user inputs one among a number key, a direction key, the goto key, a range designation key, and a channel update set key, for example, the user inputs either the number key or the goto key (S61 and S63), the video processor 28 sequentially receives the video of the Internet site corresponding to the channel selected by either the number key or the goto key according to the control signal through the network interface 25, the microcomputer 22, and the Internet site search menu generator 26 and displays the video on the screen of the television (S67).
When the user inputs the direction key (up/down) in order to select a desired channel (S62), the channel number selected by the direction key (up/down) is distinguished from other channel numbers and is displayed (S66). That is, the microcomputer 22 displays the selected channel number to be different from the other channel numbers in color or to have a three-dimensional outline. The channel number currently selected on the right top is displayed in the form of on screen display (OSD).
When the user inputs a range designation key (S64), the microcomputer 22 displays the channel numbers of the corresponding channel range and the list of the titles of the corresponding Internet sites on the screen of the television through the video processor 28 (S68). For example, when the user selects the range designation window corresponding to the channel numbers 41 through 50, the list of the titles of the Internet sites corresponding to channel numbers 41 through 50 is displayed on the screen of the television.
When the user inputs a channel update selection key (S65), the microcomputer 22 cancels the update setting of the corresponding channels when the corresponding channels are set updated and displays the update setting when the corresponding channels are not set updated (S69). The channels that are set updated are displayed to be different from the channels that are not set updated in color and brightness or are marked with a predetermined character (EZ).
When the user inputs the confirm key (S52), the microcomputer 22 deletes the Internet site information of the corresponding channel from the memory 21 and stops displaying the warning message (S54). When the user inputs the deletion key (S53), the microcomputer 22 stops displaying the warning message (S55) and the process returns to the step of determining whether the key signal is input (S36).
