The present invention relates to a method for searching and selecting a link in a data broadcast receiver that easily finds and selects a link of a broadcast screen in a data broadcast receiver using only a numeric button of a remote controller.                         

In general, in a digital TV (DTV) data broadcasting environment, additional data such as Hyper Text Makeup Language (HTML), which is an Internet standard, in addition to audio and video signals, is broadcasted to be viewed on a TV screen.

At this time, there are many links to other pages or media in the HTML document on the TV screen.

Until now, a remote controller or a wireless keyboard is also used as an input device of a TV. In the case of a wireless keyboard, a ball mouse is also attached to the keyboard.

Therefore, when the ball mouse is attached, the link is displayed while moving the mouse on the screen to select the link.

However, in the case of a keyboard, the user can select a link by clicking on it after moving between links using a direction key or the like.

Also, in the case of the remote controller, the direction keys of the keyboard are mapped to the buttons of the remote controller to select a link in the same manner as the keyboard.

As such, when selecting a link on a TV screen using a keyboard or a remote controller, the user must first go through a process of moving to a corresponding link position by pressing the up, down, left and right arrow keys on the keyboard or the remote controller. give. In particular, when the moving distance is long, the user must press and hold the direction key for a long time, and the slower the moving speed, the more the inconvenience of the user increases.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to assign a number to a link item of a data broadcasting screen, and to execute a link assigned to the number when a user selects a corresponding number using a remote controller. A link search and selection method in a data broadcast receiver is provided.

In the method for searching and selecting a link in a data broadcasting receiver according to the present invention for achieving the above object, the browser stores information on a link including a number assigned to each link currently being displayed on a TV screen, in a memory. And mapping a button (L button) necessary for link selection to the remote controller, and controlling the operation of the link selection step with the L button, and if the link selection step is activated by the input of the L button, the link selection step Reads the information stored in the memory to generate a numbered link information screen, and superimposes the link information screen on the current screen, analyzes the numeric buttons of the remote control input by the user, and finds the corresponding link when the corresponding link is found. It is characterized by informing to.

In the memory of the browser, information about a link that is changed whenever the configuration of the TV screen is changed is stored. The information about the link is a link required when the link selection step informs the browser of a link selected by the user on the TV screen. The identifier (ID), area information about what area the link occupies on the TV screen, additional information with a description of the link, and each of the link selection steps when creating and displaying an information screen for the link on the screen. And a link value which is a number assigned to each link.                     

If the L button is input, it is determined whether the current link selection step is active. If the link selection step is inactive, the link selection step is activated. If the link selection step is inactive, the link selection step is activated. The value is sent to the link selection step.

Other objects, features and advantages of the present invention will become apparent from the following detailed description of embodiments taken in conjunction with the accompanying drawings.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention comprises a browser function for storing information of a link currently displayed on a screen, a memory in which information on a link is stored, an L button of a remote controller, and an L program.

In other words, the HTML browser stores information about a link in a memory part of a document currently being displayed on a TV screen.

In addition, a button for selecting a link is assigned to the remote controller. In the present invention, the selection button is referred to as an L button for convenience of description.

In addition, there is a program in the receiver that reads information on the link stored in the memory and displays it on the screen. In the present invention, the program is referred to as an L program for convenience of description.

In this case, the L program may give information that a specific link is selected to the browser. In addition, there is a button input receiving module for sending a button event, that is, an input button value, to the L program.                     

When the L button is pressed, the L program operates to accept and process a user's input.

This will be described sequentially.

1. Save the link by browser

The HTML browser stores information about the links currently on the screen in memory. 1 illustrates an example of a TV screen, and eight links are displayed.

Whenever the configuration of the screen changes, the HTML browser stores information about the changed link in a specific area of the memory.

At this time, the information stored in the memory is largely composed of four parts.

That is, as shown in FIG. 1, the link identifier (ID), area information, additional information, and link value are provided.

First, the link ID is a value required when the L program informs the browser of a link selected by the user on the TV screen. The area information is information on which area the link occupies on the screen. That is, it includes information such as the start position, width, and length at which the link is displayed.

The additional information is stored in the memory as a stream describing the link. The link value is a number assigned to each link when the L program creates an information screen about the link and displays it on the screen. If this number is then selected on the remote control, the link is selected.

2. L button on the remote control                     

The present invention maps any button of the remote controller to the L button, and when the L button is pressed, the L program is operated. Here, the L button operates in a toggled manner, and when the L button is pressed once more, the L program stops operating. In the present invention, a state in which the L program is executed is referred to as an active state and a state in which it is not executed is referred to as an inactive state for convenience of description.

In the inactive state of the L program, the events of all the remote control buttons input after the L button is pressed (that is, the button values pressed by the user) are transmitted to the L program.

2 is a flowchart of processing a remote control button in a TV according to the present invention.

That is, if a button value is input from the remote controller (step 201), it is checked whether the L program is active (step 202). In an embodiment of the present invention, the ON variable is set, and if the ON variable is TRUE, the L program is determined to be active. If the ON variable is FALSE, the L program is determined to be inactive.

Accordingly, if it is determined in step 202 that the L program is in the active state, it is checked whether the input button value is the L button value (step 203). If it is the L button value, the L program is terminated and the ON variable is set to false to indicate that the L program has been changed to inactive state (step 204).

However, if the button value input in step 203 is not the L button value, the input button value is sent to the active L program (step 208).

An operation flowchart of an L program that receives and processes a button value output in step 208 is illustrated in FIG. 6, which will be described in detail later.

On the other hand, if it is determined in step 202 that the L program is inactive, it is checked whether the input button value is the L button (step 205). If it is determined in step 205 that the L button is executed, the L program is executed, and the ON variable is set to true to indicate that the L program is active (step 206). If it is determined in step 205 that it is not the L button, the input button value is sent to the existing remote control processing routine (step 207).

3. L program

On the other hand, when the L program is active, first, information about a link stored in the memory is read. Then, items (eg, icons) indicating that the link is displayed on the screen. 3 illustrates an example in which items indicating a link are displayed on a TV screen together with general contents not related to a link.

In this case, the information screen on the link reflects the information on the link stored in the memory.

That is, after reading the information on the link, the screen with the information on the link is superimposed on the current screen as shown in FIG. 4 is an example of a screen with information on a link, and the screen with information on the link of FIG. 4 is superimposed on the general screen of FIG. 3 and displayed as shown in FIG. 5. In FIG. 4, the number next to the link box is a link value assigned to each link. When the user selects the number through the remote controller in a state in which the information on the link is overlapped as shown in FIG. 5, the link corresponding to the number is selected. Is executed.                     

At this time, in one embodiment, the region corresponding to the link region may be transparent as shown in FIG. 5, and the remaining portion may be opaque. And, depending on the degree of opacity, information other than the link can be made invisible.

As such, when the user inputs a button of the remote controller while the information screen for the link is displayed, the L program as shown in FIG. 6 operates.

At this time, the L program is terminated when the L button is pressed again by the user or a link is selected. In the active state of the L program, it accepts the numbers 0-9 from the remote control and holds them until the selection button is reached. When the selection button comes, the number is analyzed and the corresponding link is found. If a link corresponding to the number is found, a message is sent to the browser indicating that the link is selected, and the L program is terminated.

In other words, when the L program is started in FIG. 6, there is no number string stored (step 601). At this time, if a button of the remote controller is pressed (step 602), it is determined whether the input button value is a selection button value (step 603). If the input button value is not the selection button value, it is determined whether it is a numeric button value (step 604). At this time, if it is not the numeric button performs a general operation corresponding to the input button value, or wait until the numeric button is input.

On the other hand, if it is determined in step 604 that the numeric button value, the number is added to the existing numeric string and stored, and then returned to step 602 (step 605). This process is repeated until the select button is input.

That is, if the link value you want to select is 3, the user presses the number button 3 on the remote control and then presses the select button. If the link value you want to select is 11, press the number button 1 on the remote control twice in sequence Press the button.

After the above process is performed, if it is determined that the input button value is the selection button value in step 603, the stored numeric string value is set as a link value (step 606). Then, it is checked whether link information corresponding to the set link value is on the TV screen (step 607). If it is determined that there is link information corresponding to the link value, the HTML browser is notified that a link corresponding to the link value is selected (step 608), and the L program ends (step 609). At this time, the ON variable is set to false to indicate the end of the L program.

Then, the link corresponding to the link value is executed through the browser.

As described above, according to the link search and selection method in the data broadcasting receiver according to the present invention, the user may display an information screen on a link assigned with a number through the L button, and the remote control may display the number assigned to the link. By selecting and executing, the user can more easily check the link value in the data broadcasting HTML document, and it can be convenient for the user since the user can select the link with fewer buttons than the conventional method.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.                     

Therefore, the technical scope of the present invention should not be limited to the contents described in the embodiments, but should be defined by the claims.
