The present invention relates to a television service (hereinafter referred to as an IPTV service) using an internet protocol network, and more particularly, to a menu screen display method and a set-top box for allowing a user to easily select a menu in an IPTV service.

Recently, with the spread of broadband media and the increase in communication speed, the Internet has emerged as a new medium for enabling One source Multi Service. As an example of such one multis services, a number of airwave television and radio channels, as well as multimedia contents provided by an internet service provider are provided as a broadcast service through the Internet. Along with the rapid increase in the Internet use population, the demand for internet broadcasting that provides OneS multi-service is on the rise.

A representative service that emerged from this background is IPTV (Internet Protocol Television) based on Internet Protocol.

The biggest feature of IPTV is that it provides bi-directional television broadcasting service through high speed internet.

The IPTV connects a content providing server and a display device connected to the Internet through a set-top box, and displays an information content service, a video content providing service, and a broadcasting content providing service through a display device. By providing it to the user.

In addition, in addition to the above-mentioned broadcasting service, IPTV has an increasingly diverse function due to integration of Internet service, data broadcasting service, and personal video recorder (PVR) service.

As service functions gradually diversify, IPTV needs to build a user interface that provides various menus for users.

1 is an example illustrating a screen on which a menu screen is displayed in an IPTV service according to the prior art.

As shown in FIG. 1, various menu items 1b are displayed for each category on a menu screen 1a of an IPTV service according to the related art so that a user may easily select a menu.

Lower menus dependent on the upper menus 1b-1 to 1b-4 have a hierarchical structure so that they can enter each upper menu.

For example, in the list of the top menu 'movies', there may be 'foreign films', 'korean films', 'melo films', 'horror films', 'SF films', etc., in each sub menu. There may be a plurality of menus depending on the genre.

However, in the conventional menu screen 1a having the hierarchical structure as described above, since the display area of the screen shown to the user is constant, it may be unreasonable to display all the menu items 1b in the limited display area.

Accordingly, an arrow-shaped moving icon 1c is added to one side of the screen to move the menu item 1b to facilitate selection of the menu.

However, such a display method is also possible as a user performs a movement operation, and since some layers or pages must be moved on the first page, a delay and an error of the display may occur when the system is loaded. In addition, a user who does not see the moving icon 1c may not be provided with various services because the user cannot see the menu item 1b hidden on the next layer or page.

The present invention was derived to solve this problem, and the user can display various menu items displayed on the menu screen, especially hidden menu items that are not displayed on one screen due to space limitation, so that the user can view them without a user's manipulation. An object of the present invention is to provide a menu screen display method for easily selecting a menu and a set-top box for implementing the same.

And a controller for scrolling the menu screen to sequentially display menu item information not displayed on one screen when the menu screen is authorized, wherein the menu screen includes a higher menu item that classifies the plurality of content lists into upper categories. At least a lower menu screen to be displayed, and lower menu items subordinate to each upper menu item, and the lower menu items are hierarchically displayed so as to directly enter according to the selection of the upper menu item. The control unit is the upper menu When one upper menu item is selected on the screen, the lower menu items dependent on the selected upper menu item are read and output, and the scroll operation of the upper menu screen deactivated according to the detection of the state sensing unit is stopped, and the state detection is performed. The lower menu screen activated according to the detection of the negative may be scrolled if there is no user's operation for the predetermined time.

According to an example of the present invention, the set top box may further include a display screen for visually displaying a signal output through the output unit.

However, the present invention is not limited to the above-described process sequence, and may be performed even when other menu screens are displayed, without being limited to the initial menu screen in FIG. 7.

That is, while the initial menu screen or other menu screens are displayed, the set-top box detects the reception state of the input signal receiver and checks whether there is an operation request from the user (S200).

As a result of the check, if there is an operation request from the user, the operation type is identified.

For example, it is determined whether the type of the requested operation signal is the movement of the menu item (S210). If the movement of the menu item is correct, the menu item is moved in one direction (S220).

If the menu item is not moved, it is determined whether the next requested operation signal is the selection of the menu item (S230).

If the selection of the menu item is correct, the corresponding menu item is selected (S240), or another form is identified and the corresponding operation is performed (S250).

On the contrary, if there is no operation request from the user as a result of the check, the process returns to step S130 of FIG. 7 to check whether a predetermined time has been exceeded.

This whole process checks the user's operation for a certain period of time, and performs the corresponding operation when there is a user's operation. However, if there is no user's operation, the menu items hidden by the user are scrolled by scrolling through the menu items of the currently displayed menu screen. These methods are for sequentially displaying them.

Next, as another embodiment, a method of displaying a scroll screen by activating a menu screen will be described.

9 is a flowchart illustrating a menu screen display method according to another embodiment of the present invention, wherein the menu screen refers to a comprehensive menu screen including the upper menu screen as well as the lower menu screen.

Initially, when the user moves to a lower (or higher) menu at the request of the user, the set-top box reads and displays the lower (or upper) including the lower (or upper) menu items from the storage (S300 and S310).

Here, when the lower menu can be moved from the upper menu as shown in Figures 5a and 5b, or when moving to the secondary sub-menu in detail from the primary sub-menu dependent on the upper menu as shown in FIG. It includes.

In addition, the upper menu may move from the lower menu, and includes all cases such as after watching the content, watching the content, and stopping in the middle.

If a certain time is exceeded while the lower (or upper) menu screen is displayed, the lower (or upper) menu that is not displayed on the first page of the lower (or upper) menu screen by scrolling through the lower (or upper) menu screen. Menu items are sequentially displayed (S320 to S340).

In addition, while the lower (or upper) menu screen is displayed, it is possible to check whether or not the user is operating (S400).

As a result of the check, if the user's operation is performed (S410), if there is no user's operation, it returns to the next step S320 to check whether the user's operation request for a certain time.
