  Conventional television receivers (hereinafter referred to as “TVs”) receive television broadcast radio waves and display their images, but with the introduction of digital technology, more functions are planned. It is being developed as a generation TV. Next-generation TVs can take in the functions of conventional computers, such as Internet connection functions, and enable more advanced information processing.

  However, television is one of the major home appliances, and has a different character from information processing devices such as personal computers. Even though television (especially digital television) and personal computers are technically similar, their personality and usage are very different. Therefore, it is necessary to develop a user interface for a next-generation television that is different from that of a personal computer and suitable for the next-generation television. For example, a personal computer is equipped with a keyboard and mouse as input devices, but a television has only a remote control and a few switches on the main body, and it is inappropriate to use the personal computer user interface as it is.

  An object of the present invention is to provide a user interface suitable for a next-generation television.

The present invention is a next-generation television receiver including a television receiver, a user interface processor, and a display unit that displays an image output from the television receiver and a user interface generated by the user interface processor. And
The user interface processing unit includes:
A file (hereinafter referred to as “gadget”) for displaying an image (hereinafter referred to as “gadget”) on a part of a TV screen, and is a file that can be played back by Flash Player (trademark) , “Swf file”), a definition file (hereinafter referred to as “xml file”) including the name of the swf file used for the gadget and the name used when selecting the gadget, and the gadget A folder containing application programs to execute the functions of
A core activation step of activating a program that uses the folder (hereinafter, the activated program is referred to as a “core”);
Gadget display step for displaying the gadget by calling Flash Player based on the swf file of the folder in the core;
A gadget activation step of activating the application program in the core and starting a process associated with the gadget (hereinafter, the displayed gadget and the started process are referred to as “child apps”);
A request step in which the child application issues a keyword prepared in advance to the core as an FSCommand used to send a message in Flash;
A search step of receiving the FSCommand in the core and searching for it from a list of functions predefined in the core;
An execution step of receiving a search result in the core, calling Flash Player to execute the function of the result, and executing the function is executed.

  The next generation television and the program for realizing this user interface according to the embodiment of the invention will be described.

  An apparatus / program according to an embodiment of the present invention realizes an application rich in design based on an existing image processing program Flash.

  The apparatus / program according to the embodiment of the present invention is a “mechanism” for allowing a digital gadget to appear on a screen, which is resident in a next-generation television. Gadgets are created based on Macromedia Flash and are displayed richly on a personal computer screen, and provide a suitable user interface.

  The next-generation television is a future television equipped with communication and other functions, and is currently being developed. There are various meanings of next-generation televisions, and some manufacturers refer to thin large-screen televisions as next-generation televisions. However, next-generation televisions according to embodiments of the invention will be described with reference to FIGS. .

  In FIG. 1, 1 is a next-generation television. The next-generation television 1 shown in FIG. 1 includes a television receiver, a display unit (such as a plasma display and a liquid crystal display device), a remote controller, a USB, i. Interfaces such as LINK and LAN are provided. The USB can display a photograph taken by connecting a digital camera 201 on a TV screen, or a keyboard or mouse 202 can be used as a next-generation TV as a personal computer. The interface according to the embodiment of the present invention can be easily executed without using the keyboard or the mouse 202. i. The HDD recorder 301 can be connected to the LINK. A personal computer 101 or a LAN HDD recorder 103 can be connected to the LAN, or a broadband router 102 can be connected to connect to the Internet 401.

  In the following description, there is a description that processing / operation is performed using a keyboard, mouse, or browser. However, the keyboard, mouse, and browser are not essential for the television. According to the embodiment of the present invention, a desired process can be executed without using them. There seems to be a difference in contact distance as a big difference between TV and PC. A TV is a thing that is used far away, and in that situation, it seems that it will be difficult to adjust the mouse especially when there is no desk at hand. Also, browsers basically have many interface sites where information is listed, so it seems not suitable for browsing at that distance.

  FIG. 2 shows a schematic configuration of the next-generation television 1. An image of the conventional television receiver 12 is displayed on the display 13, and an image (details will be described later) of the user interface processor 11 according to the embodiment of the invention is displayed on the display 13. The image by the user interface processing unit 11 is displayed superimposed on the television image or displayed in a separate window. The user interface processing unit 11 includes a CPU, memory, and I / O, performs image processing equivalent to that of a personal computer, and also receives information from the television receiver 12 (for example, index information (URL of a program included in a television signal). Including)), a predetermined process is executed. For example, the information is displayed on the display unit 13, or a predetermined server on the Internet 401 is accessed based on the information to acquire / display the information. A specific example of processing will be described later.

  The user interface processing unit 11 causes the digital gadget to appear on the screen. A gadget (gadget) is displayed richly on a screen and provides a suitable user interface. The user interface processing unit 11 includes an OS and has functions similar to those of a personal computer. In the following description, the user interface processing unit 11 may be referred to as a personal computer, and the screen of the display unit 12 may be referred to as a desktop.

  A gadget means a smart accessory or a little mechanical device. In the present specification, a small image displayed on a screen of a next-generation television or superimposed on a television image or displayed on a separate screen (window) by the apparatus / program according to the embodiment of the invention is referred to as a gadget. Gadgets can be dynamically expressed by animation, characters can be written, and some processing such as search can be executed.

FIG. 3 shows an example of a gadget. FIG. 3 shows a part of the screen, and W is a window of another application.
A is an eye gadget that follows the movement of the cursor. Two adorable eyeballs are always displayed on the desktop, following the movement of the cursor.
B is a digital clock. C is a calendar.
D is a memo. The memo is writable, can be placed at any position on the desktop, and can be colored with any color (including intermediate and transparent colors).

The gadget has the following features.
(1) An animation displayed on the screen of the next generation television. The animation is small (the number of pixels constituting the animation is small), and the position can be set freely. Therefore, it does not hinder the viewing of TV images.
(2) A specific process can be executed by giving a command to the gadget from, for example, a remote controller. For example, a specific website can be browsed or a search can be executed.
(3) The image expression is rich. Not only can it be represented by the animation described above, it can be of any shape, shaded, colored with a neutral color, and so on. Since it is based on Flash, it is easy to create the image. Moreover, the correction is also easy. Conventionally, there are images having a gadget-like function, but their expression is poor. This is because, in order to enrich the image expression, a lot of labor was required for its creation, and such expression means were not supported. In addition, there were many difficulties in correcting the image for the same reason as requiring labor. In contrast, gadgets are based on Flash, so they are easy to create and modify.

Flash is software developed by Macromedia that creates Web content by combining animations of voice and vector graphics. The resulting content is sometimes called Flash. There is also a function to provide bidirectionality by mouse or keyboard input.
To view files created with Flash, you need to install a dedicated plug-in "Flash Player" in your web browser. Flash is paid for, but Flash Player is distributed free of charge. It is similar to the company's “Director”, but it is easier to operate than Director, and because the shape is managed in vector format (parameters of the equation of the curve connecting the vertices), the size of the created file is also small. Although it is inferior to Director in terms of advanced functions, it has become widespread because it appeared as an animation tool that can withstand practical use for the first time on the Internet where the line speed is still slow.

The procedure for displaying the gadget is as follows.
(1) Create a Flash Player file (swf) for the gadget in Flash. This is no different from normal swf. If the file is played by IE or Flash player, it will be displayed in a rectangular window.
(2) Start the apparatus / program according to the embodiment of the invention. Flash Player is called while the program is running. The program itself according to the embodiment of the invention does not have the function of Flash Player, and calls the Flash Player in itself like a browser such as IE.

  Next, the device / program according to the embodiment of the invention will be described.

<Folder structure>
The folder structure of the device / program according to the embodiment of the invention is as shown in FIG. 4, for example. When creating an application, it is common to package all materials and use them as a single exe. On the other hand, in the apparatus / program according to the embodiment of the present invention, for example, as shown in FIG. 4, packaging is not performed and the executable file and the visual file to be reproduced exist separately. The reason for this is to realize the following matters.
・ Functions can be added flexibly later on a gadget basis. ・ Users can add and delete functions. ・ There are two types: gadgets that can be operated by the user and gadgets that are automatically displayed during the operation.

FIG. 5 shows an example of the xml file.
・ <Gadget>:
type: Indicates the type of gadget.
version: Gadget version number <gadget><swf>:
Swf file name used for the gadget <gadget><title>:
Name used for menu and gadget selection screen ・ <gadget><list>: Specify whether to display in menu ・ <gadget><menu><fix>: Fixed front setting ・ <gadget><menu><config>: Setting dialog settings ・ <gadget><menu><config_filename>: Settings dialog html file name ・ <gadget><menu><help>: Help settings ・ <gadget><menu><help_url>: Help URL
・ <Gadget><author>: Author name

  In the device / program according to the embodiment of the present invention, when exe is started, it is confirmed that there is a gadget folder in the lower directory, and if there is a folder under gadget folder that has gadget.xml, gadget Appears as a window on the desktop according to the contents of the .xml.

This produces the following effects.
-When providing an environment to allow users to use multiple applications, a safer application usage platform than the relationship between the start menu and applications on Windows (trademark) can be realized (user execution rights are significantly limited) (Because all the programs that use the OS functions are common, bugs are unlikely to occur.)
-It looks like middleware for providing services on Windows (trademark) (similar to the concept of plug-ins).
Information expansion that is not bound to a rectangle like an Internet browser is possible (because the device / program itself according to the embodiment of the invention moves in a form of a browser without a frame).

<Communication between child and core>
Normally Flash files can be played back in a local environment, but for example, you cannot save the file or take the mouse coordinate position from within the entire display. This is because Flash files are usually provided as plug-ins, and it is used to make it harder to make viruses with Flash.

  The device / program according to the embodiment of the invention functions in the form of a browser that plays Flash instead of IE on Windows (trademark), but Flash originally has an interface called FSCommand for communicating with an external program. ing.

  Script is a simple program that can be easily executed without converting to machine language. Usually, a program is executed by converting it into machine language that can be understood by a computer based on the source code (design drawing) written by the programmer, but the process is automated and can be executed easily. . In particular, a simple program for using various functions on a Web page that cannot be done with HTML alone is sometimes called a script. Languages for writing scripts (script languages) include Perl, VBScript, and JavaScript.

  The device / program according to the embodiment of the invention monitors the behavior of the Flash being played back as a browser, and when the Flash issues an FSCommand, receives it and confirms its contents.

  The program according to the embodiment of the present invention is provided with a plurality of functions for using the OS function, and the functions can be executed through the FSCommand. Upon receiving the command, the apparatus / program according to the embodiment of the invention executes an action that cannot be realized in Flash as a substitute for Flash.

  This makes it possible to create Flash as an application interface creation platform that goes beyond Flash in a normal browser.

  The above will be further described with reference to FIG. FIG. 6 executes a function corresponding to save (file saving), and when some content comes out as a result, the device / program according to the embodiment of the invention executes it and displays it through a child gadget ( The outline of the process of displaying the result on the display unit 13) is shown. In FIG. 6, 10 is a child gadget, 20 is a program according to an embodiment of the invention (may be described as “core”), and 21 is a function list (command name and command name) provided in advance in the core 20. The function is described).

  After being activated, the child gadget 10 issues a keyword prepared in advance by the program according to the embodiment of the invention as an operation on the FlashPlayer as an FSCommand (S20). In the case of FIG. 6, the request is an issuance of FSCommand, and in this case, a command “save” is issued.

  The program according to the embodiment which is the core 20 searches for “save” from the predefined function list 21 (S21), and executes the function corresponding to “save” (S22).

  In the case of FIG. 6, the function is file saving, but some contents appear as a result, and the program according to the embodiment of the invention executes it and displays the result on the desktop through the child gadget 10. Let it come out.

  Next, a procedure for executing the processing of FIG. 6 on the next-generation television will be described. Although the next-generation TV has the same functions as a personal computer, it usually does not have a keyboard or mouse as its input devices. Therefore, it is not possible to adopt the same procedure as a personal computer. Therefore, we propose a procedure for using a TV remote control. That is, the user interface processing unit 11 is turned on / off and the above-described core activation and child selection / activation are executed from the remote controller. An example of the procedure is shown in FIG.

To start the core, for example, the following is performed.
・ Turn the jog dial on the remote control to bring up the launcher (core) and display the list of gadgets (children) you want to activate. The gadget description is displayed during selection.
・ Launch the gadget (child) by clicking the jog dial. The gadget first appears at a fixed position. When other gadgets exist, the space adjustment is automatically performed based on a certain algorithm.
-There is a button at the index finger position when holding the remote control. When the jog dial is turned while pressing the index finger button, the gadget active currently displayed on the display changes.
・ There are several actions in gadgets, but it is difficult to perform mouse operations and detailed operations on next-generation TVs, so the shape of the gadget can be looped by placing something like a shape change button on the remote control and hitting it repeatedly. You may make it change with.

<Version up>
The apparatus / program according to the embodiment of the invention has an automatic version upgrade function so that the service is always executed in the latest state (FIG. 8). A list of files is downloaded from the server 30 (S30), the file is confirmed (S31), the file is downloaded (S32), and additional changes and deletions can be made in accordance with the designated state (S33). This function ensures future scalability.

<Communication with browser>
In order for an application and a browser to communicate with each other, it was necessary to develop a plug-in that can communicate with the browser.

  On the other hand, in the apparatus / program according to the embodiment of the present invention, since plug-in software such as Flash is played back internally, the function of the plug-in software such as Flash (local connection) is used to communicate with the browser. Communication was possible.

The apparatus / program according to the embodiment of the invention performs the following processing (FIG. 9).
The child application 20 always stands by as a signal waiting state.
In this state, when the user displays the corresponding page of the browser 40, communication starts (S30).
A function corresponding to the received signal is selected (S31).
The core 10 receives the signal, performs necessary processing (S32), and returns the signal to the browser side if necessary (S33).

  With the above processing, it is possible to say that an operation on the desktop occurs due to a command from the browser, or a change occurs on the browser due to a command from the PC.

  Conventionally, only browser-browser communication has attracted attention, and no attempt has been made to use it for application-browser communication. The communication between the application and the browser according to the above procedure is newly created by the inventor.

<Drag and drop between browser and application>
Using all the above techniques, it is possible to realize object movement that looks like a drag-and-drop between a browser and an application by the apparatus / program according to the embodiment of the invention.

This process will be described with reference to FIG.
Reference numeral 40 denotes a browser. There is Flash 41 in the browser 40. Reference numeral 20-1 denotes a communication child application. In order to communicate with the browser 40, it is necessary that the Flash file to be communicated with is always on the desktop. For this purpose, an invisible gadget that has a communication function with the browser (which can be made transparent with the alpha channel as described above) is always started on the desktop. When the drag drop appears, the core 10 causes the communication child application (invisible gadget) 20-1, the destination child application (puzzle sheet in the case of a puzzle) 20-2, and the drag child application (in the case of a puzzle). Three gadgets called 20-3 are attached.

  The communicator application folder has, for example, swf file: all background, all transparent alpha information. The app executes a process of receiving a signal from the browser and sending it to the core.

  The drag child application folder is, for example, an swf file: an image of a pointer (a piece that sticks to the mouse in the case of a puzzle), and the application executes a process of sending the position of the pointer to the core.

The destination child application folder is an arbitrary image (a puzzle sheet in the case of a puzzle). The application receives coordinates from the core, displays an object there, and communicates with the browser.
-Clicking on an object on the browser 40 causes communication (S40). That is, the communication by the local connection is generated from the swf file reproduced by the FlashPlayer in the browser 40. Communication between swf files being played by FlashPlayer is a function called “local connection” of Flash.
When the communication is received, the communication child application 20 instructs the Flash 41 to delete the object. A command for causing the gadget 20-3 to appear so as to be dragged to the coordinate position of the mouse is issued, and a command for hooking the mouse to the appearing gadget 20-3 is issued (S41).
When the gadget 20-3 is released at a destination location, a target communication start command (in the case of a puzzle, a command to start a process in which pieces stick to the puzzle sheet), a gadget 20-3 end command (S42), An object display command is issued in the application 20-2 (S43).
If the gadget is released at a place other than the destination, an object re-display command is issued to the Flash 41 in the browser 40 (S42), and an end command for the gadget 20-3 is issued (S44).

  As a flow linked to the appearance of the desktop, the banner on the home page is clicked, the communication child application 20-1 is communicated, and the destination child application is activated (dragged) depending on the situation, and dragged to the current mouse position First, the child application is displayed and the drag child application is hooked to the mouse (drag state), and then the flow moves to A or B.

The above “target communication” may be anything, and therefore the application range of the apparatus / program according to the embodiment of the present invention is wide. For example, the following is possible.
-Copy text information-Copy files-Install programs-Move permission information (point service, etc.)
・ E-commerce (transfer product information to gadgets with payment function)

<Screensaver>
A screen saver can be realized by the program according to the embodiment of the invention.
On PCs, Windows (trademark) has a function to automatically launch apps when the user is not operating to protect the display. The application that starts up is the screen saver. It is possible to provide a screen saver function in the next-generation television, which may be different from the conventional television. In the description of the screen saver in this section, Windows (trademark) is exemplified as the OS, but the OS of the next generation television is not necessarily Windows (trademark). The apparatus / program according to the embodiment of the present invention can be operated on an operating system capable of realizing other Internet communications.

  The program according to the embodiment of the invention installs a screen saver program as a general-purpose frame that can be controlled from the program according to the embodiment of the invention as a screen saver selected from Windows (trademark) at the time of installation. At this time, the screen saver program is different from gizmo.exe which is the actual state of the program according to the embodiment of the invention.

  The screen saver program refers to the ss folder in the folder in which the program according to the embodiment is installed. This includes an XML file that describes what you want to play and a swf file that you want to play.

The operation of the screen saver according to the embodiment of the invention will be described with reference to FIG.
The program 20 (ss folder program) according to the embodiment of the invention reproduces the swf file to be reproduced this time as a screen saver based on the contents described in the xml file (S50).

  At the end of reproduction, the xml file is referred to again to reproduce the next swf file (S52).

  Thus, when a plurality of screen savers and information are distributed simultaneously, in the embodiment of the invention, the screen saver is terminated when the user touches the mouse. At the end, the program 20 according to the embodiment communicates with the screen saver program 50. The gadget linked to the displayed content is activated as the child application 10 (S51, S53). For example, the child application 10 can guide a user who has returned to the seat to a specific homepage.

  In the conventional screen saver, a specific operation (for example, the operation of the child application 10) can be performed only by explicitly operating the user. However, according to the embodiment of the present invention, the specific operation is not performed. Can be executed.

  This can be realized because the screen saver program 50 and the program according to the embodiment of the present invention are handled as one separate program. In the past, as represented by point casts, the same program approach was used for both.

  According to the next generation television (FIG. 2) according to the embodiment of the present invention, the following processing is possible.

(1) By saving the programs and personal information normally used on the PC and the settings of the gadgets used by the user in a database on the Internet, the TV has a function as an attention window for referring to it. Service like.
According to this service, complex operations are possible. For example, when the time limit set on the PC comes, a display related to the setting automatically appears on the television screen.
・ Incoming mail from a specified person ・ Incoming telephone call from a person in the address book ・ You can refer to the same RSS information you see on C with an RSS reader etc.

(2) When a button on the remote control is pressed, a launcher (core) is displayed on the screen, and the function can be called arbitrarily.

(3) As stipulated in digital broadcasting such as terrestrial digital, the contents broadcast together with the program are not regarded as the contents linked to the program, but only the index information is distributed, and the URL is sent to the index. The content linked to the broadcast content can be acquired with a single button (for example, information on the broadcast program is acquired through the Internet, the combination of CM and online shopping, the combination of program content and database, etc.). That is, an application (child) corresponding to the index information is activated, and the content is acquired by the application. According to the embodiment of the present invention, a plurality of applications (children) can be prepared, and the production thereof is easy. Therefore, the manufacturer can produce and provide necessary applications even when the index information increases, and the cost can be suppressed. The application can be easily added to the television of each home by the above-described version upgrade function. On the other hand, since the user only has more menus, the operation method using the remote controller does not change, and there is no need to understand how to use each application.

  FIG. 12 shows an example of combining CM and online shopping. The CM display metadata linked with the broadcast content (S60) is flowed (S61), and the device / method according to the embodiment of the present invention is linked to accumulate the profile including the user's action history inside. (S66). It is possible to provide a mechanism in which the metadata and the profile are multiplied, and CM information that is cached in the television from the CM database is pushed and displayed at the CM display timing (S64).

(4) The next generation TV can be an attention tool in a home network. For example, an incoming call notification is displayed on a television screen. If a telephone is connected to the USB or LAN, an incoming call can be notified on the TV screen. At that time, it is also possible to search the telephone directory based on the caller ID notification and display the caller information. In addition, the state of the refrigerator can be displayed, the chime of the door can be notified, the state of the kitchen and bath can be notified, and the state of the delivery box can be notified.

(5) In addition, a clock / calendar can be displayed, or music can be started to play music. Information such as online news and weather forecasts can be obtained from the Internet and displayed.

(6) Provide a home server or its control function. Since home appliances are digitized and have a communication function, data exchange occurs between devices. The next-generation television may have a server function for providing the data to each device, or the server function may be controlled by the next-generation television. For example, an apparatus / program according to an embodiment of the present invention can easily perform operations such as displaying an image of a digital camera on a next-generation television and sending it to a printer as needed or sending it to a friend by attaching it to an e-mail. Can be executed. That is, an application (child) that executes the process is started from the core, and data transmission / reception is instructed by a drag-and-drop operation. Data transmission / reception instructions are completed simply by dragging and dropping image thumbnails from the digital camera icon to the printer or Internet icon. Although it seems that it is difficult to perform such an operation only with a remote controller, according to the apparatus / program according to the embodiment of the present invention, a user interface can be easily created. The operation can be easily done by preparing. For example, the application (child) is executed to display icons of cameras, televisions, printers, and the Internet, and to display an image of an arrow connecting them. When a predetermined remote control switch is pressed, the combination of devices to which the arrow is connected changes, and when the desired combination (for example, from the camera to the printer) is reached, an execution button is pressed to instruct data transmission / reception.
