The present invention relates to a device and methods of data entry to display the screen for entering data, the receiver-decoder, television system, program product for a computer, the storage medium that can be read by the computer, and signal. Aspects of the present invention is particularly (but not exclusively!) applicable in consumer electronic devices, such as receivers-decoders to work with digital television signals. At the same time, aspects of the present invention can also find application in General purpose computers and other equipment.

In this text, reference is made to the filed at the EPO application 00300832.3 on behalf of the company CANAL + Societe Anonymous, the contents of which are incorporated in this text by reference.

Devices with digital keyboards panels are increasingly being used to perform tasks involving the recording of information, including text, using the keypad. For example, mobile phones are used to enter information in the phone's memory, for example the names in the phone book this phone, or to send text messages. Other examples include the use of remote control of the TV to set text on a television screen, for example, when you access the Internet using the phone is visor, equipped with a receiver-decoder.

Typically, such devices have only a numeric keypad with keys for each digit from 0 to 9 and possibly a few other keys, such as "#" and "*". In order to be able to enter text, requires at least 26 additional key functions for the letters of the alphabet and, in addition, requires several key functions for upper and lower case (uppercase/lowercase), punctuation marks and symbols, and letters from the apocryphal icons (accented letters).

In the famous rocker panels used for text input, each key is assigned to several functions, and the user sequentially and cycles through the available options by pressing the key several times, and these different functions are usually displayed on the screen. When the user reaches the desired function of the button, this function is usually selected by pressing the selection key or move the screen cursor. Obviously, when it is necessary to provide a complete set of functions, each key keypad is necessarily associated with several different functions. For example, key "2" keypad can have the following functions: a, b, C, a, b, C, 2, D, d, b, B, b, b, a, a, e, E, W, W, 3, C, and may additionally have the function symbols. Whenever Tr is need for a specific letter, a number or symbol, this key has to be pressed several times. Obviously, this can take a long time and is inefficient. In addition, design constraints and physical size of the keys often lead to the fact that not all the letters and symbols that can be accessed using any specific keys can be displayed to the user. Thus, if the user wishes to enter any letter or symbol, he often has to resort to trial and error to find the key that is associated with the same letter or symbol.

The solution which is used for some models of mobile phones, is to use the QWERTY keyboard (keyboard containing keys in accordance with the American standard position of the keys), but it definitely is not ideal for cases where it is desired a small keypad : the keys should be large enough that they can be used.

Overview system description, digital television

On figa shown in General, the system 1 digital television. The present invention provides basically conventional system 2 digital television, in which to transmit compressed digital signals are known, the system compression ratio corresponding to the MPEG-2 standard. Specifically, MPEG-2 compressor 3 in the broadcast center receives a stream of digital signals (typically a stream of video signals). The compressor 3 is connected to the MUX-scrambler 4 by connecting 5.

The multiplexer 4 receives a variety of other input signals, assembles transport stream and transmits the compressed digital signals in the transmitter 6 of the broadcast center via a connection 7, which, of course, can take many forms, including telecommunication links. The transmitter 6 transmits electromagnetic signals on channel 8 "Earth-satellite to satellite transponder 9, where they are subjected to electronic processing and broadcast virtual channel 10 "satellite-to-Ground on the roadways to the receiver 12, usually having the form of plates, owned or leased by the end user. Possible, of course, other transport channels for transmitting data, such as terrestrial broadcasting, cable transmission, the combined cable and satellite channels, a telephone network, etc.

The signals received by the receiver 12, are transmitted in a combined receiver-decoder 13, owned or leased by the end user and is connected to the TV 14 end user. The receiver-decoder 13 decodes the compressed MPEG-2 signal in the television signal to the television 14. Although figa shows the individual receiver-decoder, it can be part of an integrated digital TV. The term "receiver-decoder"as it is used in this text, covers and a separate receiver-decoder, such as a set-top box for TV (STB)and TV with integrated receiver-decoder.

In a multichannel system, the multiplexer 4 handles audio and video information received from multiple sources, and communicates with the transmitter 6 to broadcast this information on the appropriate number of channels. In addition to audio-visual information in some or all of these channels can be entered messages, or applications, or digital data of any other kind, interspersed with transmitted is or the audio and video information.

To the multiplexer 4 and the receiver-decoder 13 is connected, the system 15 conditional access, placed partly in the broadcast centre and partly in the receiver-decoder. It allows the end user to access the digital TV of one or more providers of broadcasting. In the receiver-decoder 13 can be mounted smart card is able to interpret the messages related to the commercial offerings (i.e. one or more television programs that are sold by the provider of the broadcast). Using receiver-decoder 13 and the smart card end-user can buy a commercial offer or subscription mode or in the mode of payment for a view (PPV). The term "smart card", as it is used in this paper covers (but not limited to!) any device in the form of a card containing a chip, or an object with similar features and performance, and is equipped with, for example, a microprocessor and/or memory device. This term also encompasses devices having other maps physical form, such as a device in the form of a key, such as those often used in systems with television decoders.

As mentioned above, transmitted in the above-mentioned system scribblenauts multiplexer 4, and the conditions and keys Shi is the formation, applied to a particular transfer, determined by the system 15 conditional access. Transmission of scrambled data in this manner is well known in the field of pay-TV. Usually scrambled data are transmitted together with the control word destined for diskriminirovaniya these data, and self control word encrypted using the so-called working key and transmitted in encrypted form.

Scrambled data and the encrypted control word is then accepted by the decoder 13, having access to the equivalent working key stored on a smart card installed in the decoder to decode mentioned encrypted control word and then descrambling the transferred data. Paid for a subscription, the subscriber will receive, for example, in the transmitted monthly to the ESM (the message RMS) working key necessary for decoding the encrypted control words which makes watching.

Interactive system

Interactive system 16, also connected to the multiplexer 4 and the receiver-decoder 13 and also placed partially in the broadcast centre and partly in the receiver-decoder, allows the end user to interactively communicate with a variety of applications through reverse modem channel 17. This reverse is demny channel can also be used to exchange information, the system uses 15 conditional access.

Upon request of the end user interactive application menu and then executes the commands, and provides data corresponding to the purpose of this application. Applications can be either resident, i.e. stored in ROM (or flash memory, or other non-volatile memory) of the receiver-decoder 13 or transmitted by broadcast and boot in RAM or flash memory of the receiver-decoder 13.

Applications are stored in the memory cells in the receiver-decoder 13, and are represented as resource files. The resource files can, for example, to include the library files descriptions of graphical objects, library files, blocks, variables, files, sequences of commands, files, applications and data files, as described in more detail in the aforementioned patent descriptions.

The receiver-decoder includes a memory divided by the volume of RAM, including flash memory and the ROM, but this physical structure is different from the logical organization. The memory can be further divided into the volume of memory associated with the different interfaces. On the one hand,the memory can be considered as part of the hardware; on the other hand, the memory can be viewed as supporting or containing in itself the whole system, shown separately from the hardware.

Software architecture

You can consider the Central processor 220 as having its main function of ensuring subsystem 4008 support the implementation, which is part of the virtual machine 4007. She on one side (side a "high-level") is connected to the application, and on the other side (side "low") - through various intermediate logical device, described below, hardware 4061 receiver-decoder that includes a variety of ports mentioned above (i.e., for example, a serial interface 221, a parallel interface 222, the modem 223 and block 226).

Contact fig.2b; with the virtual machine 4007 associated with different applications 4057; some of the applications that are used relatively frequently, can be more or less permanently resident in the system, as indicated by the position 4057, while other applications will be loaded into the system, for example, from the MPEG data stream or from other ports as needed.

In addition to the subsystem 4008 runtime, the virtual machine 4007 includes features 4006 resident library, including the Toolkit 4058. In Biblio is ECU includes various functions in the C language, used by the subsystem 4008, including those used for data processing, such as compression, decompression, or comparison of data structures, drawing lines, etc. Library 4006 also contains information about the hardware and software (firmware) of the receiver-decoder 13, such as version numbers of hardware and software and the available RAM, as well as the function to be used when loading a new device 4062. You can download functions in the library and stored in flash memory or ROM.

Subsystem 4008 support execution connected with the Manager 4068 devices connected to the multiple devices 4062, which are connected with drivers 4060 devices, which, in turn, is connected with the ports or interfaces. In a broad sense, the device driver can be considered as defining a logical interface, so that two different drivers can be connected to a common physical port. The device is typically connected to multiple device drivers; if any device is connected to one driver, such a device is typically implemented in such a way as to combine all the features required to perform data transfer, so there is no need for a separate device drivers. Some devices can communicate with one another.

In software architecture, the reception is the IR decoder 13 each function of the receiver-decoder 13 is represented as a device 4062. Devices can be either local or remote. To local devices 4064 include smart cards, European unified connector SCART (SCART), modems, serial and parallel interfaces, turntable MPEG video and audio information and a means of extracting MPEG-sections and MPEG tables. Remote devices 4066 implemented in a remote location, different from the local device to that port and the procedure should be determined by the Manager or the developer, not the device and the device driver is developed and provided by the manufacturer of the receiver-decoder.

Subsystem 4008 support the execution of works under the control of the microprocessor and a common application programming interface (API). They are installed in each receiver-decoder 13 so that all the receivers-decoders 13, from the point of view of applications, identical.

Subsystem 4008 performs application 4056 on the receiver-decoder 13. She performs interactive applications 4056 and receives events from the outside of the receiver-decoder 13, displays graphics and text, refers to devices with requests for services and for certain calculations uses the library functions 4006 connected to a subsystem 4008.

Subsystem 4008 support implementation is an executable code installed in each receiver-decoder 13, and contains terpreter for interpreting and executing applications. Subsystem 4008 compatible with any operating system, including single-tasking operating system (such as MS-DOS). Subsystem 4008 is based on the use of blocks of sequential processing (automatic) (which take on different events, such as pressing a key, to perform in response to different actions) and contains its own scheduler to manage queues of events of different hardware interfaces. It also controls the display of graphics and text. Block sequential processing (process sequencer unit) contains a set of action groups. Each event translates a block of sequential processing from its current group to another group actions depending on the nature of the event and triggers the execution of the actions of this new group.

Subsystem 4008 contains the boot loader code to download the applications 4056 in the memory of the receiver-decoder. To ensure optimal use of resources in RAM or flash memory is loaded only the necessary code. The downloaded data is verified using the procedures of checking the authenticity in order to prevent any change in the application 4056 or execution of unauthorized applications. Subsystem 4008 also contains the decompressor. Because the application code (a kind of intermediate code) is compressed to save space and to expedite the program downloads data from the MPEG stream, or through the built-in modem receiver-decoder, this code should be decompression before it is loaded into RAM. Subsystem 4008 also includes an interpreter for interpreting the application code to update the values of different variables and determine state changes, and check for errors.

The architecture of the receiver-decoder

The receiver-decoder has five software levels that are organized in such a way that the software be implemented in any receiver-decoder and with any operating system. As shown in figs, these various software levels are level 250 applications, the level of 252 interface applications (API level), the level 254 virtual machine, 256 level and device level 258 system software/hardware.

Level 250 applications covers applications that are either resident in the receiver-decoder, or may be loaded into it. It can be used by users of interactive applications that are written, for example, Java, HTML, MHEG-5 or other languages, or it can be the application used by the receiver-decoder to perform such applications. This level is based on the set of APIs provided by the virtual machine level. This system allows you to download apps in flash memory or RAM of the receiver-decoder is perative (as needed) or on demand. Application code can be transmitted in compressed or uncompressed form using protocols such as DSMCC, NSF or other protocols.

The interactive application is an application with which the user interacts, for example, to get the goods, facilities or services, such as e-guide programs (EPG), applications for banking operations (telebanking) and games.

For these downloaded applications and data provides a variety of security measures, such as:

nothing can be loaded into the receiver-decoder without prior assurances of its suitability for this network that prevents the receiver-decoder of any of the unregistered software. This means that any running in the receiver-decoder software recognized and fully tested;

- security Manager restricts the access of applications to different memory regions, thereby ensuring the integrity of data;

- this system can communicate with any conditional access system in which processors are used for security (for example, a smart card installed in the receiver-decoder).

To control interactive applications uses the following memory-resident applications:

- Loading. The boot application 260 is the first application, run after switching on the receiver-decoder. The boot application starts the various "managers" of the virtual machine, the first of which is the Manager 262 applications.

Manager applications. Manager 262 applications manage interactive applications running in the receiver-decoder, i.e. starts, terminates, suspends, resumes, handles events, and organizes the exchange of data between applications. It allows you to simultaneously run multiple applications and thus participates in the allocation of resources between them. This application is completely transparent to the user.

- Set. The purpose of the application 264 configuration is the configuration of the receiver-decoder, mainly when you first use it. It performs actions such as scanning frequencies to find the TV channels, set the date and time, set user options-preferences, etc. however, the setup application may be used by the user at any time to change the configuration of the receiver-decoder.

- Switching channels. The application 268 channel is used to change channels using the arrow keys on the program up, program down arrow and numeric keys. When using other forms of switching channels, for example the EP with the help of banner (pilot) applications (banner, pilot application), the application switching channels is completed.

- Callback. The application callback is used to retrieve the values of the various parameters stored in the memory of the receiver-decoder, and return these values to the commercial operator through the modem back channel 17 or by other means.

Level 252 API provides a high-level tool for developing interactive applications. It includes several packages that form this high-level API. These packages provide all the functions necessary to run interactive applications. These packages are available for access applications.

In one of the preferred embodiments of the present invention, the above API level is adapted to run applications written in the Java programming language. In addition, he can interpret HTML and other formats, such as MHEG-5. In addition to these interpreters, it also includes other packages and service modules, which can optionally be switched off and expand.

Level 254 virtual machine consists of language interpreters and the various modules and systems. It includes everything necessary for the reception and execution in the receiver-decoder interactive applications, including the following:

- Language interpreters. For whom the devices match the type of application, which will be read, can be installed in different interpreters, including interpreters, Java, HTML, MHEG-5 and others.

Subsystem service information (SI subsystem). SI-subsystem loads and controls the normal DVB-or PSIP tables and places them in the cache. It provides access to these tables applications that need contained in these tables.

- Scheduler. This module allows multithreaded preemptive scheduling, in which each thread has its own event queue.

- Memory Manager. This module controls access to the memory. He also optionally automatically compresses the data in the memory and performs an automatic "garbage collection".

- Event Manager. This module allows you to handle events according to their priority. He controls the timer and capturing events and allows applications to send events to each other.

- Dynamic linker. This module allows you to perform address translation using eigenfunctions Java, downloads native methods Java class that is loaded into RAM, and allows you to make calls to the ROM downloaded from your own code.

- Loader. This module uses the automatic download of data from a remote DSMCC-carousel or via the NFS Protocol, with access to downloaded the m files in the same way, as a resident. There is also the memory scrubbing, compression, and authentication.

Manager classes. This module loads classes and solves any problems with links to the classes.

- File system. This module is compact and optimized for managing a hierarchical file system with many different volumes - ROM, flash memory, RAM, and DSMCC memory. Guaranteed the integrity of the flash memory in case of any unforeseen circumstances.

The security Manager. This module checks the authenticity (authenticity) applications and controls the access of applications to critically vulnerable memory and other parts of the console for the TV.

- Graphic system. This system is object-oriented and optimized. It provides, including the management of graphics Windows and objects, and also includes a subsystem vector fonts with multi-language support.

Moreover, supported the proposed Council on digital audiovisual technologies (DAVIC) model resource notifications (resourse notification model that ensures effective management of resources of the client.

Level 256 devices includes device Manager and the device. Devices are software modules, consisting of logical resources needed for working with external with what itemi and physical interfaces. The device controls the data transfer channels between the drivers and applications and provides superior system to prevent errors. Here are some examples of supported devices: card reader, modems, network, PCMCIA card, LEDs, etc. Programmers do not need to apply directly to this level, because the level API manages the devices on the top.

Level 258 system software/hardware provided by the manufacturer of the receiver-decoder. Thanks to the modularity of the system and the fact that utility functions provided by the OS (such as event scheduling and memory management)are part of the virtual machine, the upper levels are not tied to any particular operating system real-time (RTOS) or any particular processor.

In the example below describes an implementation option of the present invention used in a Web browser of the receiver-decoder. The structure and operation of such Internet browser are discussed more fully in European patent application 00300832.3.

The user uses a web browser with a TV and uses a control device TV (or similar device) to navigate in the browser.

Figure 3 shows an example of a control device, with OSU which the user can navigate between objects on the screen (i.e. to navigate, select objects, and select objects. In this example, used by the control device is remote 1180 remote control for the TV. For data entry keys 1181; for screen navigation toolbar is used 1182 cursor control. Panel 1182 cursor control contains the key "up" 1183, press "down" 1184, press "left" 1185 and press "right" 1187. Panel 1182 cursor control also has a selection key 1186, which is used to select objects on the screen.

Key "up" 1183 and key "down" 1184 used to move the focus, in this example, the backlight up and down. After illumination of the object can be selected using the selection keys 1186.

Such a receiver-decoder provides the opportunity to work with the Internet and reading e-mail.

Consider now the graphic Studio for the simulation Navigator. Part of this graphic Studio is a "virtual keyboard", which is used for data input in the browser.

Graphic Studio to model Navigator is a set or collection of primitive graphical objects. Each graphical object is a clear view on the TV screen one of the functions of the Navigator. Each function of the Navigator can be represented by graficheskim object or a sequence of images of a graphic object (animated image, or a set of graphical objects (for example, the image on the screen background or background picture dialog box, which may be subject to other graphical objects). There are two internal image format: MPEG-2 and PIXMAP-GRL.

For elementary graphical objects representing the functionality of a "navigation system" - loading, linking, previous document, next document, the output, and so on - use the PNG format.

To overlay a non-rectangular image on the graphics plane, you must use the clip mask that defines the visible (important) areas. This mask may be provided by the designer in the form of a bit array; this mask is not calculated by the program due to limitations on computational power.

The two stages of adding a shut-off masks are displaying a first image, and then, in this graphic plane, filling a rectangle with the same dimensions and coordinates, as mentioned image, transparent color with a simultaneous imposition of the cutting mask, so as to make visible the "useful" part of the image.

The image format PIXMAP-GRL is used for graphical objects representing resources navigate the RA or the user interface: the vertical scroll bar, tables, simple choice, multiple choice, etc.

Objects of type PIXMAP are objects of variable size (each graphical object or model is broken down into simple elementary objects), which is painted (colour changing).

The image format PIXMAP-GLR can be obtained by converting from any image formats (such as BMP, JPEG, GIF, PNG etc) using known methods.

Mentioned splitting of the graphical object on the graphical primitive objects (elements) is performed in accordance with some matrix (e.g., 3×3, 4×4 or 1×4)the selection of which depends on the type of the displayed object.

Maximum screen size is 720 pixels wide and 576 pixels high. To ensure the ability to display on any TV lowest price class, it is necessary to limit these sizes up to 592 pixels in width and 480 pixels in height. To optimally use the TV's high price class, the user can adjust the size of the screen. For an Internet browser pages typically have dimensions of 600 pixels wide and 400 - height.

The focus can be presented in different ways: the selection rectangle for graphics; emitting light (other CEE who ω) of the background graphic object or path selection of the graphical object color.

Normal condition (without focus, active, pressed) is the main state of the graphics object.

Forbidden state of the graphical object may be represented in various ways: the contour of the object shown in gray (or vegetarian); the corresponding graphical object superimposed distinct prohibition sign; background object is changed to monochrome; the object is invisible.

"Pressed" state of the graphics object is a graphical representation of the focused object after pressing but before you release the key. This representation can be inverted image of the object or may be the same as the representation of the object that has focus.

Below is basic information about several of the graphics used in the Web browser interface, and their respective functions.

Below is a non-exhaustive list of more of the graphical objects, which are required to build the model Navigator in the decoder. In the following table these objects are listed elementwise and given a list of objects composed of several graphical elements.

Table 1

Table 2

Let us now describe the Java API for the Web browser.

Below is a list of several Java packages that are used in the decoder at the application level Navigator. This list is divided into two parts: the classes in the AWT (Abstract Window Toolkit) package of JDK 1.1 and Java interface classes of the different services, written in pure C-code.

The package Navigator, called the th service browser combines different packages: package browser.drawer"providing services that allow the reading in memory of the HTML document and implement navigation in the browser document; and package mediawebtv"that allows you to connect to the Internet with user authentication.

The proposed Navigator uses all available graphics (MPEG, PIXMAP) graphics Studio. Accessing functions or select from several options displayed on the screen is performed by moving the focus using the arrow buttons (remote control) or by using a keypad with cursor/pointer. The choice of some action is performed by pressing ("clicks") the control device or by using a predetermined button (for example, "OK").

In the absence of a physical keyboard for text input using the remote control it is necessary to provide the virtual keyboard. This is achieved by moving the focus with the possibility of quick dialing by displaying (i.e. match) buttons on the remote control to the virtual keyboard; in other words, the image of the virtual keyboard visually displays a contour or slightly opaque image buttons on the remote control. More virtual to the aviatour discussed below.

Optimally button is a rectangular or square area (for example, 32×32 pixels). When the graphics cursor is in a certain area, this area (box) receives focus (cf. function "EnterNotify(WindowId)").

If the graphical image button has, for example, the shape of the tire, you will have to determine whether there is a practical ceiling of pixels that bus the actual position of the graphic cursor. For this purpose it is necessary to determine the value of the pixel in the "hot" point indicated by the mouse pointer in the shut-off mask this button (by calculating the relative position, call getpixel() to shut off the mask and then checking the value of a pixel). This detection method allows you to make more effective checking whether produced press ("click") before the function of this button.

When the mouse pointer leaves a rectangular or square area of the button, this area loses focus (cf. LeaveNotify)WindowId)).

Below, with reference to Fig.4-7, will be examined in more detail virtual keyboard.

Figure 4 schematically shows how visible at the moment virtual keyboard (1501) is displayed in the background "grid" virtual keyboards (1501, 1506).

Figure 5 shows a typical distribution of symbols on the keys of the virtual keyboard.

Figure 6 shows used for the virtual keyboard image, where the focus is respectively the first (1545) and the second (1546) digital blocks (also shown two different types of remote controls - 1542 and 1543).

7 shows a typical layout of the virtual keyboard with indication of typical sizes.

First, the virtual keyboard is conceived as a tool, not dependent on the application in which it is used. Accordingly, it can be used in Web-browser ("WebBrowser") and, similarly, in e-mail ("Mail"). Moreover, its appearance is completely independent from the "appearance" of the application with which it is used.

The virtual keyboard is displayed when a user who does not have a physical keyboard or a remote control with keyboard, selects allow editing (i.e. one in which you can edit) the area of the screen. The focus is set at the end of the text in this permit editing area. Pressing "OK." (on the remote control or virtual keyboard) or "Cancel" (on the virtual keyboard) removes it.

The virtual keyboard is visible on the screen (1501), formed by three blocks (groups) of ten buttons each (representing three of the keypad of the remote control), adjacent (1502, 1503, 1504). The user mo the em transmit focus (1505) from one unit to another using the arrow keys of the remote control. After selecting a block pressing member of the keypad of the remote control enters the corresponding symbol drawn on the virtual keyboard.

The user can also use the "arrow up" and "down arrow". It displays the same virtual keyboard, but with other characters on the keys (1506). Thus, sorting the set of 5 virtual keyboard, the user can display all characters from the keyboard of the Western computer. There is also the possibility of adding other keyboards when needed.

As shown in Fig.6, in order to immediately establish a correspondence between the digital unit of the remote control and the focus placed on the virtual keyboard focus is indicated overlaid with a transparent image of the remote control (1542, 1543). Thus, the user can easily see that only one part of the keyboard has focus and that access to the rest of the characters can be provided by moving the focus with the arrow keys. This keyboard is created with the following.

The height of the virtual keyboard is small relative to the height of the screen and allows you to easily increase the number of available characters. The default is virtual the keyboard with miniature alphabet.

Some buttons have an important special functions:

- Click "OK" on the remote control to confirm the current selection (if this field has only one line, the symbol ¶ (1521) is also proving or, in the alternative, it may not cause any action; otherwise, it matches only the carriage return).

- Cancel button "Cancel" (1522) on the virtual keyboard is used to exit this service program without confirmation (changes made after open the keyboard, will be lost).

- Press "Backspace" (1523) on the virtual keyboard deletes the last character entered.

- Button up arrow, down arrow, left arrow and right arrow buttons to move through the editing area.

Button tab ("Tab") (1520) on the virtual keyboard at a time inserts a set number of spaces (default is four).

The keyboard is always in "insert"mode.

An example of a keyboard presented on Fig.6 and is discussed further below.

With five keyboards (5×3)shown in figure 5, and the two fonts that are installed for the application WebBrowser (Arialweb and Courier), you can cover all the characters of the traditional keyboard. The size of the keyboard on the screen are 272 pixels wide by 184 pixels high

Virtual keyboard and functional relationships, operated when it is used in various applications, implemented in the package "canalplus.virtualkbd".

This package includes, including classes MhwVirtualKbd (class graphic descriptions of the virtual keyboard and describe the behavior of the virtual keyboard), "MhwVkText Field" (a class derived from "java.awt.Text Field, which allows the virtual keyboard created from the main application, use the TextField class, to work with events) and "MhwTextArea (class inherited from "java.awt.TextArea", which allows the virtual keyboard created from the main application that uses the class TextArea, to work with events).

Describe a few more class MhwVirtualKbd".

The class constructor "MhwVirtualKbd" is defined as "private". Accordingly, when starting the main application, which you may want to use the virtual keyboard (for example, when no physical keyboard), you can create only one virtual keyboard. The goal is to provide a keyboard that is specially configured for the current application and appears when the user enters data in the text field (single line or multi-line).

After creating the keyboard are four basic (static) variables, which can konfigurera the AMB:

- parent"container, "ancestor" of the virtual keyboard, which must exist at the inception of the keyboard. It is defined using the method of "setParent", which returns the value "NullPointerException if passed as argument "ancestor" - "null".

- descriptive file: an ASCII file that describes the keyboard as in graphics displayed behind the image, with regard to the different "keyboards", obtained when using the virtual keyboard, and the signs, markings on the keys. The symbols indicated by their unicode code. The descriptive name of this file can be set using the method setScreensFile".

- "the number of screens number of digital blocks (groups of digital keys), initialized and used by the virtual keyboard. This is the number that is specified by using the method of "setScreensNumber", corresponds to the number of keyboards, the characteristics of which are read from the above descriptive file.

- "source coordinates": these are the coordinates of the top left corner of the background image of the keyboard in the container-ancestor (described above). They are using the method "setCoordInit".

After the keyboard is created, you can decide whether to use it or not, by using the method "getInstance", which finds the keyboard for the current application, if any (what if virtual keyboard for this application does not yet exist and if the application uses such method "getInstance" creates a virtual keyboard, using the variables [four previously described]that need to be set).

Let us now describe the event handling.

As mentioned above, virtual keyboard, as shown, operates exclusively through the interpretation of events, send her a digital unit (group of numeric keys), press "OK" and the four arrow keys of the remote control. For the keyboard, these keys have special functions.

Key "OK" is important because it allows the user to do two things: "return" in the text box to enter information and then display the virtual keyboard and start its work and to leave this text box and save changes.

Arrow keys

"Arrow right" and "left" allow you to move the image of the remote control (pointing digital block that has "focus") on one of the three digital blocks presented on the virtual keyboard. Thus, the keys of the keypad of the remote control is "attached" to image different characters depending on the "keyboard"that has focus.

In the most General case, the "hits" on these buttons, when the virtual keyboard is active, invoke the automatic insertion of the symbol is, shown in the key at the current (active) text box in the position indicated by the cursor.

Of the six characters can be considered "special" and they do not lead directly to the display in the text box of the character shown on the key.

Return one position with erase (Backspace): "<" (1523): when pressed on the remote control corresponding to this symbol button deletes the character immediately to the left of the cursor position in the current text field.

Tab (Tab): "≫" (1520): when pressed on the remote control corresponding to this button symbol at the current cursor position inserts the specified number of spaces ("), default - four.

Enter: "¶" (1521): when pressed on the remote control corresponding to this button symbol at cursor position insert a "line". In fact, if the current text field is an instance of class "MhwVkText Field, i.e. a field with only one editable string, "kick" button or not will have no consequences, or to confirm the entry in this field. If, on the contrary, this text box is an instance of class "MhwVkTextArea", it will consist of several editable rows and this symbol will trigger the "line" (if the cursor POS is n on the last edited line "blow" this button will not have any effect).

Cancel:(1522): when pressed on the remote control corresponding to this symbol button all changes made in the current text box after opening the virtual keyboard, are cancelled. In other words, its contents again becomes the way it was before you made these changes, and the "output" of the virtual keyboard.

Left arrow: pressing the remote control corresponding to this symbol button the cursor in the current text box is moved one position to the left. If the cursor is already in the "zero" position (moving further to the left is impossible), pressing this button has no effect.

Right arrow: pressing the remote control corresponding to this symbol button the cursor in the current text box moves one position to the right. If the cursor is already positioned after the last character in the text box (and cannot be moved further to the right), pressing this button has no effect.

Up arrow: pressing the remote control corresponding to this symbol button the cursor in the current text box is moved up one position. If the cursor is already on p is pout line text field (or if this text box is only one line - class MhwVkTextField), pressing this button has no effect.

Down arrow: pressing the remote control corresponding to this symbol button the cursor in the current text box is moved down one position. If the cursor is already on the last line of the text field (or if this text box is only one line class MhwVkTextField), pressing this button has no effect.

Method "find Location" determines the placement of the virtual keyboard on the screen, trying to minimize "cut" the surface.

Class "MhwVkTextField" is simply a development of the class "TextField" from package java.awt". Additionally it supports a Boolean value that specifies to use (or not use) the virtual keyboard.

Constructors are the same as the constructors of the class "TextField" in the package java.awt", with a simple additional argument: a Boolean value that indicates whether to use the virtual keyboard.

If this Boolean value is "true", create a "base" class instance "TextField" and at the same time using the method "add Key Listener" adds "the listener" (listener) for the virtual keyboard that is available in the current application. Otherwise it creates a "normal" TextField.

When the TextField has focus, if the user clicks "OK" and mentioned Blvd is in the value specifies the virtual keyboard is used, the virtual keyboard is displayed and receives focus. It handles all events and allows you to edit the text field. If the user presses "OK", this is confirmed by the text and the keyboard returns the focus. If you use the virtual keyboard is not provided (Boolean value is "false"), "behavior" of this TextField will be the same as the behavior of the standard TextField from package java.awt".

Class "MhwVkTextArea" is simply a development of the class "TextArea" from package java.awt". Additionally it supports a Boolean value, which specifies the use of (or failure) of the virtual keyboard.

Constructors are the same as the constructors of the class "TextArea" in the package java.awt", with a simple additional argument: a Boolean value that indicates whether to use the virtual keyboard.

If this Boolean value is "true", create a "base" class instance "TextArea" and at the same time using the method of "addKeyListener" adds "the listener" (listener) for the virtual keyboard that is available in the current application. Otherwise it creates a "normal" TextArea.

When the TextArea has focus, if the user clicks "OK" and referred to a Boolean value indicates that the virtual keyboard is used, the virtual keyboard you titsa on the screen and receives focus. It handles all events and allows you to edit the text field. If the user presses "OK", this is confirmed by the text and the keyboard returns the focus. If you use the virtual keyboard is not provided (Boolean value is "false"), "behavior" in this TextArea will be the same as the behavior of the standard TextArea from package java.awt".

The various above-described methods for displaying one or more graphical objects that move (navigation) between the set of such objects or receiving input from the user can equally be applied in other areas, mainly (but not exclusively!) when receiving a broadcast transmission from the provider of the broadcast. In General, such methods can be used in the exercise of any functions of the STB to the TV, providing visual interaction with the user.

For example, a virtual keyboard or other characteristics of the present invention could be used in the application to make purchases from home (home shopping)to allow the user to display the goods, to view prices, place orders and interact with the application in different ways.

With the virtual keyboard could enter any requested from the user text information, such the AK address for delivery.

In the electronic guide program (EPG) could apply such methods for interactive viewing and displaying different channels, topics, times and dates.

Other applications of the methods described above include online directories, news and weather forecasts on demand, games and General administration console for the TV (the management of its configuration and so on). In the case of games, the virtual keyboard can be used as an alternative control device for games more complex types.

It should also be borne in mind that all of the interactions that use the remote control as described in this text can be replaced or supplemented by using a mouse (or other control moving device, such as a device with a ball (rollerball) or a joystick and/or keyboard (or any other device that has many keys), or by simulating buttons on the remote control (for example, which uses the digits 0-9; arrow keys and enter key on the keyboard), either directly (for example, using the mouse to press the buttons and keyboard to directly enter text).

The above virtual keyboard can be implemented on any device that has multiple keys, this is AK, for example, game console or mobile phone. In the latter case, virtual keyboard might appear practically as described above, on the screen of the phone (on the phone with a fairly large screen) or in abbreviated form (on phones with smaller screens). Such a reduction of the virtual keypad may entail displaying only one digital block with the characters in each moment of time, preferably with indicating characters or types of characters that can be accessed by pressing "left", "right", "up" and/or "down" (or their equivalents, for example, in the case of control device moving ball type). Reduced virtual keyboard can be used in other areas, especially in cases when to display the keyboard is very little free space.

The term "checkbox ("check box") can refer to a graphic of any shape, for example round, which can display various kinds of status, preferably two States corresponding to the state "installed" and "not installed" (but possibly more than two States), and which can change its state in a consistent way by clicking on it or when the user selects it. State "installed" can be a birdie, cross-stitch or other decorative button symbol-FL the food.

For ease of use listed below are used in this application, the terms have the following preferred values:

HTML: the language describing the documents exchanged in the Internet. The document may include links to websites, rich information, sounds and images, etc.

HTTP: the Protocol for exchanging data between Internet servers, which store the HTML documents, and the application Navigator displays these HTML documents.

MPEG-2 encoding dynamic images and sound in real time.

PPP: Protocol to communicate with remote access that allows you to connect with each other two computers via modem.

Proxy server: the server-Hosted application that provides security when connecting to the Internet, as well as buffering the HTTP and FTP requests.
