Description

Character input system and the operating method

The present invention relates to a character input system and a method of operating the same so that the screen keyboard of the screen and the numeric keys of the remote controller can be efficiently inputted using a remote controller in a home appliance. .

Today's consumer electronics products have a variety of functions suitable for the multimedia era, and unlike the traditional consumer electronics of the past, there is an increasing need for upgrading system software to improve system software performance or to implement additional functions.

Recently, with the development of large-capacity memory and micro technology, various home appliances can also operate with high performance, and a flash memory in which various programs are stored is installed in the home appliance, and according to the user's operation When a predetermined operation signal is applied, the central processing unit withdraws a program from the flash memory and performs a predetermined operation corresponding to the program.

In recent years, with the explosive spread of televisions basically provided in each home, digitalization is rapidly progressing, and these digital televisions have become a huge and efficient information storage medium and a medium for providing information.

The digital television is a general term for a television broadcast 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 a remote controller (hereinafter, referred to as a remote controller) used for a user's convenience is becoming a trend.

In general, the remote controller is a remote controller basically provided with up, down, left and right keys, numeric keys, and function keys to receive content including text information, multimedia data, and the like in the data broadcast, and to select desired data in the content by operating a browser. Use the device.

The user selects a selection item by using the 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.

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.

Accordingly, digital TVs and set-top boxes that support interactive data services, which are the next generation of digital home appliances, will display screen keyboards (or virtual keyboards) used for text input on a conventional web path or PDA, and display them on the screen. A character input is input using a pointing input method using a cursor input method of a remote controller.

The screen keyboard that provides a user interface based on the pointing input method may display a desired character by inputting a desired character by selecting a virtual key corresponding to a required character on the screen when the user needs it, such as a character input. will be.

However, such a screen keyboard method is a remote control of a general TV cursor input method when a user inputs a character of purchase information for electronic commerce or a character to input a title or change a content of a program recorded on a PVR. As a result, the user interface is very inconvenient to look at the screen keyboard displayed on the screen by using the direction keys and the selection key, to move the cursor, and to select and input characters.

1 is a view illustrating a method of selecting and inputting characters on a screen keyboard using a general television remote control, according to an embodiment of the conventional character input system.

Referring to FIG. 1, in order to input an ID "swpark" using a TV remote control, the user moves to a character to be input by using a direction key on a screen keyboard displayed on the screen and selects using a selection key. By entering the desired character can be entered.

Here, to enter 'P' after entering the letter 'W', press the right arrow key several times to move to P through E, R, T, Y, U, I, O on the screen keyboard, and then select the remote control. It is entered using the key.

However, if characters are entered in this way, a total of nine key presses must be performed for the direction key eight times and the select key once. If there are many characters to be input, the keys to be pressed increase exponentially. .

Therefore, when the user needs to enter text in this manner, the input time is very time-consuming and considerably cumbersome, and the character input user interface is very inconvenient.

The present invention divides the keyboard of the screen keyboard into multiple windows so as to correspond to the numeric keypad of the remote controller when it is necessary to input a character when using a home appliance, and displays the keyboard keys of the remote controller in correspondence with the numeric keys of the remote controller. By providing a character input system and its operation method to enable efficient and fast character input by pressing the number keys of the remote controller corresponding to the desired character in the window of the screen keyboard that contains the desired character at the time of character selection.

In the step of selecting a key of the remote controller, when the selection or confirmation key is pressed, a character input from the character input initialization step is transferred to a higher level program requesting a character input, and the screen keyboard disappears from the screen.

In the initializing of the text input system, a screen keyboard having a keyboard divided into a plurality of multi-window windows, a status window showing shift key and cap lock states, and a text input window displaying text input by the user are displayed on the screen. It is characterized by showing.

Each key of the selected divided keyboard and a key of the remote controller are matched to correspond to each other and displayed on the screen.

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

2 and 3 are embodiments according to the present invention. FIG. 2 is a conceptual diagram illustrating a screen keyboard divided into five multi-windows to correspond to the numeric keys of a remote controller, and FIG. 3 is a limo. It is a conceptual diagram showing what is finally displayed on the screen by key matching between the numeric keypad of the oot controller and the screen keyboard window.

Referring to FIG. 2, the keyboard of the screen keyboard is divided into five multi-window windows so as to correspond to a numeric keypad including a total of 12 keys, horizontal 3 and vertical 4 of the remote controller.

There is an area of characters included in each window on the keyboard, which is divided to correspond to the numeric keypad of the remote controller.

One window of the screen keyboard divided as shown in FIG. 2 is key-matched with the numeric keypad of the remote controller, as shown in FIG. 3.

In Windows 3, each of the keys 6, 7, 8 / T, Y, U / G, H, J / B, N, M is 1, 2, 3/4, 5, 6 on the numeric keypad of the remote controller. / 7, 8, 9 / Corresponds to the keys *, 0 and #. Here, the keypads 1, 2, and 3 correspond to the keys 6, 7, and 8, and the keys 6, 7, and 8 correspond to the case where two letters are assigned to one key, respectively. You should be able to choose ^, &, *. This is usually done by selecting a shift key. If you want to select the CAP lock key or the shift key, select window 1 and select the numeric keypad 7 or 8, * or 0 on the remote controller. When the cap lock key is selected, a letter conversion from uppercase letters to lowercase letters or lowercase letters from uppercase letters is generally performed.

Therefore, when the user wants to input the character included in the window 3, if the user moves to the window 3, the final screen keyboard as shown in Figure 3 is displayed on the screen.

The user inputs a desired character by selecting the corresponding numeric key corresponding to the remote controller while looking at the number (mark) matched with the screen keyboard on the screen.

In the above, the movement between the windows of the screen keyboard may be moved to the window to which the desired character belongs by using a direction key (move key).

 Therefore, a total of 15 keys including 10 numeric keys, 2 mark keys (*, #), 2 left and right direction keys used for moving between windows, and 1 key for selection or confirmation, are provided in a general remote controller. The key can be used to provide an efficient character input method.

Use the remote controller to move to the window containing the character you want to enter using the arrow keys in the multi-window on the on-screen keyboard to enter the ID "swpark". By selecting a number corresponding to the character to be input in the window can be input the desired character.

Here, to input 'P' after entering the letter 'W', move from window 2 to window 4 by using the right direction key, and at this time, the number key displayed in the window 2 key matching is displayed on the window 4 To be matched and displayed.

In addition, when the user presses the number '6' corresponding to the letter 'P', which is a character to be input on the window-matched screen keyboard, on the numeric keypad of the remote controller, the corresponding character 'P' is inputted. .

In this case, since the right direction key 2 to move from the window 2 to the window 4, the numeric key 1 for selecting the character to be input in the window 4, and a total of three key presses are required, fast character input is possible.

Here, a status window displaying a shift and cap lock state and a text input window for displaying an input content of a selected character are displayed together on an upper portion of the screen keyboard. The status window displays a state in which a shift key is pressed and a state in which a cap lock key is pressed. A shift key is a key for selecting other characters assigned to one key, and a cap lock key is used to switch between uppercase and lowercase letters. Key. For example, as shown in FIGS. 2 and 3, when the number 2 key of the remote controller is selected in the keyboard corresponding to the window 3 while the shift key is pressed, & is input, and the window 3 is displayed with the cap lock key selected. If you select No.7 key in, letter g is inputted and g is entered when cap lock key is not selected. In general keyboard, if one key is assigned letter depending on whether the shift key is selected, it is converted to uppercase / lowercase letter.

5 is a block diagram of a character input system according to the present invention.

The text input system includes a user input unit 100 to which a command signal is input to perform a predetermined command from an external input means, a screen processor 120 displaying a screen keyboard, a window, a status window, and a text input window on a screen; A system controller 130 for controlling, calculating, and processing a key matching table 110 corresponding to a keyboard of a screen keyboard divided into windows and keys of the external input means in a one-to-one manner, and a user input unit, a screen processing unit, and a key matching table. It is configured to include.

As the external input means, a conventional remote controller is used.

Looking at the operation of the character input system having the above configuration as follows.

First, when a text input state is selected in the upper program, for example, when an edit control is selected in the browser screen and becomes a text input state, the system controller 100 initializes the text input state and displays the screen keyboard and the state on the screen through the screen processor 120. Display the window and the text entry window.

At this time, the system controller 130 obtains key matching information of the remote controller that matches the window of the initial state in the key matching table 110.

That is, in the key matching table 110, the keyboard of each divided screen keyboard window and the numeric keys of the remote controller are matched one-to-one with each other.

Therefore, the key matching table 110 obtains key matching information of the remote controller that matches the key of the window set as the window of the initial state on the screen keyboard, and the system controller 130 obtains the key matching information. By using the screen processing unit 120, keys (numeric keys and mark keys) of the remote control are displayed on the initial window.

Next, the system controller 130 waits for the input of the remote controller key input through the user input unit.

The user moves to the window containing the character to be input on the screen keyboard by using the left and right direction keys of the remote controller and the numeric key / mark key displayed on the moved window (corresponding to the character to be input). Select from the numeric keypad of the remote controller.

In this manner, the character selected by the user is input to the character input window on the screen.

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

When the text input state is entered during data broadcasting, the text input system is initialized (S100).

For example, when an edit control is selected in a browser by entering a character input state in an upper program, the character input system is initialized.

When the text input system is initialized, the remote controller enters a standby state (S110).

In this case, a screen keyboard having a split window, a status window showing shift key and cap lock states, and a text input window showing characters input by the user are displayed on the screen.

In operation S120, a direction key is moved from the initially set window of the displayed screen keyboard to a window including a character to be input by the user.

The remote controller key information is displayed on the moved window (S130).

At this time, each key of the window and the numeric key of the remote controller are matched to correspond to each other.

After the user moves to the window containing the character to be input, the remote controller key information on the window is viewed, and a numeric key matching the character to be input is pressed on the remote controller to select it (S140).

Characters selected and input by the user are stored and displayed (or updated) in the character input window (S150).

If the user presses the shift key or the cap lock key, the status information is temporarily stored and displayed (or updated) in the status window of the screen.

On the other hand, when the user finishes inputting the character and presses the selection or confirmation key, the character entered by the user from the character input initialization step is transferred to the upper level program requesting the character input, and the screen keyboard is erased from the screen.

Although the present invention has been described in detail through specific examples, it is intended to describe the present invention in detail, and the present invention is not limited thereto, and should be understood by those skilled in the art within the technical spirit of the present invention. It is obvious that modifications and improvements are possible.

The present invention divides the screen keyboard keyboard into a plurality of windows in order to input characters required for various next generation information appliances in the future, and displays a window including characters to be input by correspondingly displaying the numeric keys of the remote controller in each window. Just move to and press the number key corresponding to the character to be input so that there is an effect that can quickly enter the desired character in a short time.

In addition, the present invention has the effect of reducing the user's product purchase price burden because it is possible to quickly and easily enter the text only by a general remote controller even without having an external input device such as a wireless keyboard for convenient character input.

In addition, the present invention can implement a fast and efficient character input method by adjusting the arrangement of the screen keyboard and adjusting the split window to suit the remote controller used according to the present invention, even in the case of a remote controller having various key layouts. There is an effect that can be widely applied in information appliances using a remote control.
