Description

Character input system and the operating method

The present invention relates to a character input system capable of effectively inputting a character using a remote controller including a display unit in a digital broadcasting display device, and a method of operating the same.

In general, digital television refers to a general term for television broadcasting transmitted digitally. In the United States, we decided to adopt digital for the next generation of televisions called ATV (Advanced television), and in Europe, many projects such as HD DIVINE such as Swedish broadcasting, SPECTRE of the UK and DIAMOND of French broadcasting are being conducted. Research is being actively conducted in each country in the next generation television system linked with ISDN or computer network.

In recent years, the digitization of television broadcasts is progressing rapidly.

A stream transmitted in digital broadcasting may transmit data information together with a video / audio signal. Here, the data information transmitted along with the video / audio signal is based on markup data such as HTML of ATVEF (Advanced Television Enhancement Forum), XDML of Digital TV Application Software Environment (DASE), and Xlet of DASE. Java-based data information.

Therefore, in the digital broadcasting as described above, it is possible to broadcast data in various formats in addition to the video and audio that have been broadcast in conventional analog television.

In preparation for the above digital broadcasting, many companies are developing digital televisions or set-top boxes capable of receiving digital broadcasting and data broadcasting.

In particular, as the functions and data broadcasting of the digital television are diversified, the role of the remote controller used for the convenience of the user's operation becomes a trend.

In general, the remote controller receives a content including text information, multimedia data, and the like in the data broadcast, and operates a browser to select desired data in the content, and the up, down, left, right direction keys and numeric keys. Basically equipped with function keys.

The user selects a selection item by using up, down, left, and right keys, and displays data according to the selection item by using a determination key.

Conventionally, data broadcasting provides additional information to viewers when viewing digital television by transmitting data separately from the AV signal of the digital television to display the data on a digital television or set-top box incorporating a data broadcasting receiver.

In this case, a digital television or set-top box, which is a conventional data broadcasting receiver manufactured to receive the data broadcast, is provided with a remote controller for an interface with a user as mentioned above. In many cases, the minimum number of keys required is limited, so the number of keys that can be used for data broadcasting is limited.

Therefore, it is difficult for a user to control a digital television or set-top box that receives data broadcasts of various contents by using such a general remote controller.

1 is a schematic diagram showing the configuration of a remote control generally used in digital television.

Referring to FIG. 1, the conventional remote controller 100 includes a power on / off button unit 101 for turning on / off a power and raising or lowering a volume and raising or lowering a channel and adjusting a direction. Performing various data such as a direction button unit 104 for performing the operation, a number (or character) button unit 102 having a number of 0 to 9 for inputting a channel operation or required number, and a confirmation button and a cancel button. It is comprised including the function button part 103 which has a function.

However, there is a lot of difficulty in watching a data broadcast requiring various information inputs using a general remote controller having such a structure.

For example, you need to enter your ID or password when watching a data broadcast, enter a product name when you trade electronically, solve a problem by participating in a quiz program, or change the title or content of a program recorded by a personal video recorder (PVR). When a complicated remote control operation is required, such as a case for inputting a letter for a user, a lot of difficulties are involved in inputting using a remote control having a conventional limited key.

In addition, a phone number, social security number or credit card number or shipping information is required for the purchase of the product. When entering such information, the length of the string is too long to input without error. The disadvantage is that the input takes a long time because the screen and the remote controller have to be checked alternately.

In addition, in the conventional character input system, when the user wants to input the same purpose, that is, the inconvenience of having to re-enter each time every time the user inputs a string previously entered.

Although the prevalence of data broadcasting is spread as described above, since users feel a lot of inconvenience when inputting character strings using a conventional character input system, when they are reluctant to watch data broadcasting, this becomes a big problem in activating data broadcasting. .

SUMMARY OF THE INVENTION The present invention provides a character input system having a display unit and a method of operating the same so that the user can more easily input, store, and edit a character string to be pressed while watching data broadcasting. There is this.

As shown in Fig. 4A, when the telephone number is to be input in the data broadcasting content, a text box appears on the television screen and the text input state is entered.

Then, when the user needs to edit the string in the remote controller according to the string, the user selects a string edit mode key included in the remote controller.

As the character string editing code key, as shown in FIG. 4A, an 'input' key included in the remote controller may be used.

Subsequently, a telephone number is input by using a numeric key provided in the remote controller.

Then, the telephone number input by the user is displayed on the display unit of the remote controller, and the telephone number input is not displayed on the television screen.

Here, not only the desired string may be input and edited by the remote controller, but also the already stored string may be selected and used by using the direction key and the 'input' key as shown in FIG.

The phone number displayed on the display unit of the remote controller by calling a newly input or stored character string as described above may be transmitted to the television using a remote controller's key defined by a specific function, such as a 'transfer' key.

The text string transmitted in this manner is inputted into the text box of the screen and displayed as it is, as shown in FIG.

5 is a flowchart illustrating a method of operating a character input system according to the present invention.

If a textbox is generated because text input is required in the data broadcast content, the text input state is entered, and the system receives a string input signal informing that the text input state is present (S100).

As such, when the system receives the string input signal, the system determines whether a string input mode command is input from the user (S110).

When the user selects the text editing mode, the system enters the text input mode and determines whether a search command for searching for a text string already stored is input (S120).

If the search command is not input in the above, the text editing is performed in the remote controller by the user (S130).

At this time, the characters input by the user are displayed on the display unit of the remote controller and input.

However, if a string search command is input in order to use the pre-stored character string in the character string editing mode, the stored character strings are displayed on the display unit of the remote controller (S121).

Here, the user selects the character strings using the direction key and the selection key (S122).

Then, it is determined whether to use the selected character string among the stored character strings, and if the character string is to be edited, the character string is edited using a number (or a character) key, a deletion key, a direction key, and the like.

Subsequently, after determining whether to store the edited string (S140), if there is a user input for storing the string, the edited string is stored (S141).

Finally, the edited character string is transmitted to the television (S150).

Although the present invention has been described in detail with reference to specific embodiments, this is for describing the present invention in detail, and the character input system and its operation method according to the present invention are not limited thereto, and the technical field of the present invention is not limited thereto.
