Description

  The present invention relates to a method for distributing data for a digital card such as a trading card by data broadcasting, and a method and program for displaying a digital card based on the data in an information terminal device.

  A trading card is a card that contains photographs / pictures of famous professional athletes and anime characters, and is collected by the user. Conventionally, trading cards have been distributed using paper as a medium, but with the development of the Internet, it has been proposed to distribute trading cards in electronic form.

  For example, Patent Document 1 discloses a technique for exchanging trading card data by communication between a plurality of communication devices. Patent Document 2 discloses a technique for exchanging virtual trading cards on the Internet. Further, Patent Document 3 discloses a system for distributing, managing and exchanging trading cards in a mobile phone network.

  In addition, as disclosed in Non-Patent Document 1, it is common practice to provide an electronic coupon using a Web page and provide a predetermined privilege or service to a customer who presented the coupon at a store or the like. It has been broken.

  On the other hand, digital terrestrial television broadcasting has been started. In terrestrial digital broadcasting, one channel is divided into 13 segments, 12 segments are assigned to high-definition broadcasting (HDTV), and 4 segments are assigned to normal-quality broadcasting. On the other hand, for mobile terminals (mainly mobile phone terminals), one segment is allocated because the screen is small and low image quality / sound quality is sufficient, and this is called one-segment broadcasting.

  Similar to satellite digital broadcasting (BS, CS), in 1-segment broadcasting, in addition to video and audio television broadcasting and audio broadcasting services, data broadcasting services are performed. The data broadcasting service includes a multimedia data broadcasting service based on BML (Broadcast Markup Language). The data broadcasting service is described in detail in Non-Patent Document 2.

JP 2002-271253 A JP 2002-315970 A JP 2001-312602 A https: // www. tsutaya. co. jp / coupon / index. pl "TUTAYA Online Coupon" Data broadcasting technology reader, Nobuyuki Yagi, Toshiro Yoshimura, Kenjiro Kai, published by Ohm, February 25, 2002

  Based on the above-described background art, the present inventors have considered distributing trading cards and coupons (collectively referred to as digital cards in this specification) using a data broadcasting service. By using a data broadcasting service, it is possible to provide image information to an information terminal device having a data broadcasting receiving function. Thus, it is conceivable to distribute the digital card as an image file or a moving image file.

  However, simply distributing various types of digital card data in the same format and displaying them with a viewer installed on the terminal, the type of received digital card (professional baseball, anime character, or coupon) ) Is difficult to distinguish and cannot be displayed in a format suitable for each. Thus, it is conceivable to prepare a viewer for each type of digital card (card type). However, it is inefficient to mount all viewers that are unclear whether they are used on a mobile terminal in advance.

  Also, the larger the digital card data, the longer the time required for distribution. In addition, the amount of memory occupied by the mobile terminal becomes large, and the number of digital cards that can be stored particularly in an information terminal such as a mobile terminal is significantly limited.

  The present invention has been made in view of the circumstances as described above. A novel digital card data distribution method, a digital card display method, a program, and information using a data broadcasting service, which have solved the above-described problems. An object is to provide a terminal device.

  In order to achieve the above object, the present inventors distribute digital card data such as trading cards and coupons or information for obtaining the data at any timing on the broadcasting station side using a data broadcasting service, The information terminal device side receives and displays it.

  That is, the digital card display method of the present invention is a digital card display method in an information terminal device having a data broadcast receiving function, the step of receiving the card information of the digital card together with the content information by data broadcasting, and the content information And a step of displaying a user interface for instructing acquisition of digital card data related to the received card information on the display screen, and obtaining based on the card information in response to an instruction operation on the user interface by the user.

  In the displaying step, all digital card data stored in the information terminal device can be displayed as a display target in accordance with a card handling template for displaying a list of arbitrary digital cards.

  In the displaying step, according to the card handling template for displaying a list of digital cards of a specific card type, only the specific type of digital card stored in the information terminal device can be displayed as a display target. .

  In the displaying step, only the coupon card stored in the information terminal device can be displayed as a display target according to a card handling template for displaying a list of digital cards that are coupon cards.

  A step of allowing a user to select a desired card handling template among a plurality of card handling templates for displaying a list of digital cards, wherein the displaying step displays corresponding digital card data according to the selected card handling template; It can be extracted and displayed as a target. Thus, by selecting a template, only the corresponding card type digital card is extracted.

  The content information may include information for designating a card handling template for handling the digital card and / or information for obtaining a card handling template.

  The multimedia file may include image information representing an image of the entire card for each digital card. Alternatively, the multimedia file includes image information and text information unique to each digital card, and the card display template includes a common background and common text data for digital cards of the same card type. The digital card may be configured by incorporating image information and text information unique to the digital card. According to the latter, the amount of data required for communication and storage of digital card data data is reduced.

  The digital card data distribution method according to the present invention comprises a step of distributing content information by data broadcasting, and a step of distributing card information of a digital card together with the content information, wherein the card information received at an information terminal device is the information The content information includes user interface display information for instructing storage in the memory of the terminal device and is distributed.

  By using user interface display information, digital card data can be acquired only for users who need digital card data while digital card data and the like are transmitted in common to an unspecified number of broadcast receivers. it can.

  The digital card data is, for example, a multimedia file including image information and text information (character, product description, serial number, price, etc.).

  In addition, the method includes a step of distributing a digital card handling template for displaying the digital card to the information terminal device by communication or data broadcasting. Thereby, only a user who needs a digital card handling template can acquire a template.

  The digital card handling template can include action definition information that defines an action to be executed according to the card type of a designated digital card when the template is used. Accordingly, the user can execute an action corresponding to the card type by using the template without particular awareness.

  The digital card handling template may include a filtering function for extracting a digital card of a specific card type. As a result, the user can extract only the digital card of the card type by using the template without particular awareness.

  The digital card data may be composed of a multimedia file, and the multimedia file may include identification information and card type information of the digital card in addition to the image information and text information. Thereby, image information and text information necessary for a trading card, a coupon card, etc. can be handled as a single data file.

  The multimedia file may further include URL information for obtaining a digital card handling template corresponding to the card type.

  The present invention can also be grasped as a digital card display program executed in an information terminal device having a data broadcast receiving function or an information terminal device having a data broadcast receiving function.

  ADVANTAGE OF THE INVENTION According to this invention, while transmitting digital card data or the information for acquiring this to unspecified many users by data broadcasting, the mechanism in which only the user who needs digital card data acquires digital card data Can be provided.

  In particular, it is possible to realize a new broadcasting service in which digital card data or the like is distributed only to viewers who watch a certain scene of a certain program. In addition, the timing of card acquisition can be set arbitrarily by the broadcaster, so it is possible to increase the audience rating of programs and CMs by selectively providing special digital card data only to viewers who have watched a specific scene. Can contribute.

  In addition, the digital card data obtained in this way may be displayed in a card handling template to perform filtering to extract only a specific card type or to perform a predetermined action on a specific card type. It becomes possible. As a result, the user can select a digital card and perform necessary processing only by selecting a template without particular awareness.

  In addition, by including distribution source information for obtaining a digital card handling template corresponding to the card type in the multimedia file constituting the digital card data, it is not necessary to implement a program for handling the card in the terminal in advance. By downloading the card handling template, an appropriate digital card handling template can be added later. As a result, for example, even if a template that handles a digital card of a specific card type is not included at the time of terminal purchase, if a single digital card happens to be obtained, a card handling template suitable for that card is obtained based on that card. can do. Further, once obtained, the card handling template can be stored in the terminal, and thereafter used for displaying other digital cards of the same card type.

  In addition, if a card display template is adopted, digital card data distributed by data broadcasting or communication can be limited to information unique to the card, so that the time required for distribution can be shortened and the memory of the digital card on the mobile terminal can be reduced. Since the occupation amount can be reduced, more digital card data can be stored with the same memory capacity.

When a specific digital card is selected via the application unit 302, the corresponding MM file is read from the card data storage unit 324 and passed to the browser core. Further, as will be described later, digital card data filtering is executed.

  The dedicated application 310 is a dedicated application for handling a specific card type MM file regardless of the browser, and is created by, for example, Java (registered trademark) or BREW (registered trademark). The dedicated application 310 does not need to be initially present in the terminal, and can be downloaded via the communication network 27 by the terminal user.

  The card management module 312 performs reading and writing of the MM file stored in the card data storage unit 324, encryption / decryption of expansion card data in the MM file described later, copy control, falsification determination, and the like.

(About MM file)
FIG. 4 shows a configuration example of the MM file 400. As the MM file 400, for example, a standardized image / moving image file format such as a GIF file, JPEG file, or MPEG file can be used. In FIG. 4, a GIF file is taken as an example. The MM file 400, which is a GIF file, includes a file header 401, an image block 403, a sub block 405, and an end block 409. Image data 411 is stored in the image block 403. In this image file format, a comment area (comment block) 406 for inserting arbitrary information as a comment is prepared. In this embodiment, expansion card data 413 (described later) is inserted into this area. In the case of a JPEG file, the expansion card data 413 is inserted into the comment marker (COM) or the application data segment (APPn). The present invention does not exclude moving image files as MM files. Examples of the moving image file include an animation GIF file and an MPEG file. The animation GIF realizes animation by combining a plurality of GIF still image data, and can use a comment block of one GIF still image data. A predetermined area can also be used as a comment block for an MPEG file. In addition, you may use the original format only for MM file irrespective of such an existing format.

The expansion card data 413 is text information unique to the card, and can be classified mainly into the following two types.
(I) Public information:
The public information is information displayed as a card and includes the following data.
(1) Text data to be displayed in the viewer
(2) Card type: Unique data for discriminating the card type (for example, “coupon”, “baseball”, etc.). This card type is used as information for designating a card handling template for handling the digital card.
(3) Card ID: Serial number of the card type
(II) Non-public information:
Non-public information is not information displayed as a card but information stored behind the public information, and includes the following data.
(1) URL information: This information is used as information for obtaining a template distribution URL such as a card handling template, a dedicated application URL, a related site URL, and the like. Here, the template distribution URL may be either the URL set for each card or the URL of the template server 30 that distributes the template. Further, the related site URL collects, for example, the URL of the authentication server 31 for authenticating whether or not the viewer of the mobile terminal 20 shown in FIG. The URL of the accounting server 32 to be used may be used.
(2) Tampering prevention information: specific information for preventing unauthorized modification of expansion card data. Used to guarantee the consistency between image data and expansion card data.

  Whether or not to adopt these pieces of information as expansion card data is arbitrary, and the expansion card data does not necessarily include all of them. The expansion card data is preferably encrypted and inserted into the MM file. The card management module 312 executes encryption / decryption of expansion card data.

(About templates)
The template is described in BML in this embodiment. The template in the present embodiment is a card holder template as a card handling template for mainly handling a plurality of cards. However, as will be described in a later-described modification, there may be a card display template as a template in which common information for displaying one MM file is collected.

(Template for card holder)
FIGS. 5A, 5B, and 5C show examples of the card holder template in the present embodiment. In this embodiment, the following three types of card holder templates are prepared. However, not all these templates are essential to the present invention.

(1) Common viewer template: A template that can be used regardless of the card type. It is prepared by default and can display all digital cards. This is useful when there is no dedicated template. It is preferably stored in the mobile terminal from the time of shipment, but may be installed after shipment.

(2) Coupon viewer template: A template for displaying digital card data with a card type of “coupon”. Coupons are generally forms that can be used for discount sales services for specific products when presented at specific stores, etc., and code information that can be visually recognized as images such as barcodes and two-dimensional codes on mobile terminals By including the above, the terminal can be recognized and recognized by the external terminal by outputting a specific signal in a terminal having an infrared communication function. This coupon viewer template can display all "coupon" digital cards. It is preferably stored in the mobile terminal from the time of shipment, but may be installed after shipment.

(3) Dedicated template: A template for displaying digital card data of a specific card type. The dedicated template can be added to the template data storage unit 322 by being downloaded from the server, or can be deleted thereafter. Service providers (carriers, ISPs, etc.) can be authenticated and charged for obtaining and using dedicated templates. In this case, as shown in FIG. 16, an accounting server 31 and an authentication server 32 connected to the communication network 27 are added to the system of FIG. The billing server 31 provides a predetermined billing service for transactions such as paid templates (for example, download by a user). The authentication server 32 provides a user authentication service associated with billing or the like. Unlike the common viewer template, the dedicated template can selectively display only a specific card type digital card. In addition, the display items of the common viewer template can only display limited data items common to digital cards of various card types, but the dedicated template displays all data items appropriately according to the individual card types. Can do.

  Each of the card holder templates shown in FIGS. 5A, 5B, and 5C is composed of a BML document, and includes an extension script in addition to background information and character information of the card holder. The BML document of each template can include a display script and an action definition script as extended scripts. The display script describes processing necessary for displaying a digital card, which will be described later. In the action definition script, an action to be executed according to the card type can be described for the digital card selected from the list display by the card holder template. In this action, for example, all the digital cards corresponding to the card type of the digital card are displayed again using the dedicated template, or the dedicated application is started, or the coupon viewer template is displayed. It may be possible to display the digital card alone with a viewer. The action may further include downloading via a network when the designated template or dedicated application does not exist in the terminal. Or, if both a dedicated template and a dedicated app exist, use one of them preferentially or let the user select it, and if the specified template or dedicated app does not exist in the terminal, the other exists. It can be defined to use it, download it over the network if none exists, and so on. Dedicated applications can be started with an extension script. Furthermore, it is possible for the user to select what kind of action is to be performed.

  The coupon viewer template and the dedicated template further include a filtering script for extracting only the card type digital card as an extension script. In the action of the coupon viewer template, an action related to processing required when using the coupon may be defined.

  6A and 6B show two types of display examples of the card holder template. Here, examples of common viewer templates are shown here. However, the template in FIG. 6A has a three-frame display frame that can display up to three digital cards on one page, and displays an image together with the public information in the expansion card data 413 in each display frame. It is. In this example, the displayed public information is a card number, a card type, a card name, and any one item following this. The template of FIG. 6B has a display frame of 9 squares on one page, and displays only an image in each display frame. In any template, when the digital card to be displayed exceeds the maximum number of display frames per page, it is displayed divided into a plurality of pages. In the example shown in the figure, the pages can be switched by a user operation according to the user interface of “Previous” and “Next”. However, the number of display frames on one page is not limited to 3 or 9. For example, it may be 1.

(Digital card filtering)
When a card holder template other than the common viewer template is selected, filtering is performed according to the card type corresponding to the template. For example, as shown in FIG. 7, when “professional baseball card” is selected on the template selection screen 700 of the digital card viewer, the card type is “baseball” among the digital cards stored in the card data storage unit 324. "Only digital cards can be extracted and a list of digital cards can be displayed using a card holder template that is a dedicated template for professional baseball cards. In addition, when “template acquisition” 701 is selected on the template selection screen 700 shown in FIG. 7, a new template can be acquired by accessing a site that collectively manages templates via a communication network. Similarly, when “acquisition of dedicated application” 701 is selected, a site that provides a dedicated application that handles the card type digital corresponding to the template can be accessed via the communication network to acquire a new dedicated application.

(Get new card holder templates)
For example, a user selects a digital card in a state where a plurality of digital cards are displayed in a list using a common viewer template. At this time, the card type specified in the expansion card data in the MM file of the selected digital card is identified, and the action specified in the common viewer template for this card type is executed for the selected digital card. Is done. For example, when display with a dedicated template is designated as an action, it is determined whether or not a dedicated template corresponding to the card type already exists in the template data storage unit 322. If there is a dedicated template, a list of MM files is displayed on the screen of the mobile terminal using the dedicated template. If the dedicated template does not exist, the dedicated template URL specified in the expansion card data can be identified, and the dedicated template can be downloaded by connecting to the site specified by the URL through the network. With such a function, it is possible to obtain a dedicated card holder template from a digital card obtained by accident while watching a broadcast program.

(Get a dedicated app)
Further, when display with a dedicated application is designated as an action for the card type, it is determined whether or not a dedicated application corresponding to the card type exists in the terminal. When the dedicated application exists, the dedicated application is activated and a list in the MM file is displayed on the screen of the mobile terminal. When the dedicated application does not exist, the dedicated application URL specified in the expansion card data can be identified, and the dedicated application can be downloaded by connecting to the site specified by the URL through the network. However, the use of a dedicated application is not essential to the present invention.

(Digital card display)
When one digital card is selected from the list display by an arbitrary card holder template, the single digital card (corresponding to 411 in FIG. 8) is displayed alone, instead of the list display or superimposed on the list display. To do.

(Distribution of MM file)
Distribution of the MM file is performed using, for example, a one-segment broadcast data broadcast service. In BML used in a data broadcasting service for digital television broadcasting including one segment broadcasting, the following objects (functions for causing a receiving terminal to execute specific processing) are prepared.
・ SaveImageToMemoryCard: Save image data embedded in broadcast wave ・ saveFile, saveFileAs: Save file embedded in broadcast wave ・ saveHttpServerImageToMemoryCard: Save image data on communication content (HTTP protocol)
・ SaveHttpServerFile, saveHttpServerFileAs: Saving files on communication contents (HTTP protocol)
・ SaveFtpServerFile, saveFtpServerFileAs: Saving files on communication contents (FTP protocol)

  Using these objects, the mobile terminal can receive the MM file. For example, if saveImageToMemoryCard is used, the MM file can be directly delivered to the mobile terminal using a broadcast wave at a predetermined timing determined by the broadcast side. For example, if saveHttpServerImageToMemoryCard is used, it is possible to instruct the mobile terminal to acquire the MM file via the network using a broadcast wave at a predetermined timing determined by the broadcast side.

  For example, as shown in FIG. 8, when a viewer uses a mobile terminal 20 to watch a professional baseball broadcast by television broadcasting and data broadcasting, MM is transmitted by data broadcasting at the timing when a certain player is projected as a video. File distribution is performed. The display screen of the display unit is divided into a broadcast video area 81 for displaying received broadcast video (including audio) and a content area 83 for displaying BML content. Along with the distribution of the MM file, a user interface (in this example, a button 82) for soliciting the viewer to obtain a digital card (“card get”) is displayed in the content area 83. In the BML document, the button 82 is linked with a function for saving the corresponding digital card. When the viewer instructs the button 82 from the operation unit 207 (FIG. 2), the MM file including the digital card data is stored in the card data storage unit 324. Thereafter, when the viewer wants to view the card, the image is displayed by designating the digital card using a predetermined card holder template. In addition, a coupon MM file can be distributed during a specific CM broadcast. MM files of talents and anime characters appearing in the program can also be distributed.

An example of content information displayed in the content area 83 is shown below. This content information defines user interface display information and is described in BML.
-------------------------------------------------- ---------------
<Script>
・ ・ ・ ・ (Omitted)
function cardGetFunction ()
{
browser.saveImageToMemoryCard ("mycard.jpg", "mycard_save.jpg", true);
}
・ ・ ・ ・ (Omitted)
</ Script>

・ ・ ・ ・ (Omitted)
<Object onclick = "cardGetFunction ();" data = "cardGetButton.jpg" ...
・ ・ ・ ・ (Omitted)
-------------------------------------------------- ---------------

  Here, in "browser.saveImageToMemoryCard (" mycard.jpg "," mycard_save.jpg ", true)" in the script "cardGetFunction", the browser 300 uses the object (function) "saveImageToMemoryCard" to transmit by data broadcasting. It is described that the MM file named mycard.jpg is saved in the memory with the file name mycard save.jpg. Further, in “<object onclick =“ cardGetFunction (); ”data =“ cardGetButton.jpg ”...>”, The browser 300 stores the image data “cardGetButton.jpg” indicating the user interface 82 in FIG. If displayed in the area 83 and the user interface 82 is selected, execution of the script “cardGetFunction” is described.

  FIG. 9 shows a configuration example of the card management table 330 and the template management table 331 stored in the management table storage unit 326. The card management table 330 stores the above-mentioned “card ID” and “card type” and the location where the card data is stored (for example, the memory address of the flash memory) for each digital card that is effectively stored in the card data storage unit 324. ) And “dedicated template URL” indicating the acquisition location for acquiring a dedicated template corresponding to this card type. The template management table 331 shows, for example, “template ID” which is a template name for identifying each template for each template effectively stored in the template data storage unit 322, and the above-described three types of templates, for example. A “template type” and a “save location” indicating a location (for example, an address of a flash memory) where the template data is stored are stored.

  These management tables collectively manage information attached to the MM file and card holder template. The management table is not essential if the MM file or card holder template is referred to each time, but the card to be managed This is useful for shortening the processing time when the number or the number of templates increases. Although not shown, the management table is also useful when managing the acquisition date and update date of a digital card or template. Note that the data format need not be a table format, and any data format may be used.

  FIG. 10 is a flowchart showing an example of processing when a digital card is obtained along with data broadcasting by the digital card viewer (browser 300 and card management module 312) in the present embodiment.

    When the function of the TV signal receiving unit 212 of the terminal is turned on, reception of television broadcasting and data broadcasting is started (S11). The received BML content data is temporarily stored (buffered) in the RAM 202 (FIG. 2) (S12). Preferably, when the upper limit of this area is exceeded, the data is overwritten and updated from the old side. As shown in FIG. 8, when a user interface such as a “card get” button 82 is displayed in the content area 83 (S13), “acquisition of a digital card” is performed in response to a viewer's instruction operation on this user interface. The presence / absence of “instruction” is determined (S14). If it is determined that the user has issued a digital card acquisition instruction, the MM file of the digital card data temporarily stored is stored in the card data storage unit 324 (S15). Further, the card management table is updated so that the management information of the digital card data is newly registered (S16). The above process is repeated until broadcast reception is completed (S17) by turning off the function of the TV signal receiving unit 212 or turning off the power of the terminal.

  Although not shown, when the user deletes the digital card in the terminal, the data is deleted from the card data storage unit 324 and the management information is deleted (or invalidated) from the card management table 330.

  FIG. 11 is a flowchart showing an example of processing for displaying a list of digital cards using the card holder template by the digital card viewer according to the present embodiment.

  A template selection screen 700 as shown in FIG. 7 is displayed in response to a predetermined instruction operation on the terminal by the user (S21). If there is any template selection instruction operation on this screen (S22, Yes), the template data is read from the template data storage unit 322 (FIG. 2) (S23). Therefore, if there is a filtering script designated for this template, the filtering is executed (S24). That is, only a digital card of a specific card type corresponding to this template is extracted from the card data storage unit 324 (FIG. 2). If there is no filtering script (for example, in the case of a common viewer card holder template), all digital cards are extracted from the card data storage unit 324.

  As shown in FIGS. 6 (a) and 6 (b), the digital card data extracted in this way is an image (which may be a moving image) according to the action specified for the card type for the template. In some cases, a list including text information is displayed (S25). At this time, the digital card viewer reads out the BML data of the card holder template from the template data storage unit 322. Next, the number of cards is acquired using a display script which is a type of extended script included in the card holder template. A required number of pages is determined according to the acquired number of sheets, and a list (not shown) is created. This list includes MM file storage location information (URL or directory path name and file name) and identification information for identifying the MM file. An extension script can be used to acquire the position information and identification information of the MM file.

  When any one of a plurality of digital cards displayed in a list is designated by a user operation (S26, Yes), the designated action is executed on the image of the designated digital card. (S27). The designated action is, for example, display of a digital card by a browser, display of a digital card by a dedicated application, acquisition of a template, acquisition of a dedicated application, or the like.

  If the user gives a “return” instruction from an action on one digital card, typically one card display state (S28, Yes), the process returns to the list display in step S25. If an “end” instruction is given (S29, Yes), this process ends.

  In step S22, if there is no template selection and there is another instruction (for example, “return” instruction) (S30, Yes), the other process is performed (S31), and then this process ends.

  FIG. 12 is a flowchart illustrating an example of processing when a card holder template other than the common viewer template is obtained from the terminal by the digital card viewer according to the present embodiment. For example, when a specific digital card is specified in the common viewer template and a dedicated template corresponding to the card type is automatically obtained, or a coupon card is specified and the coupon template corresponding to the coupon card is automatically acquired. This process is automatically started when it is obtained. Alternatively, when the user wants to obtain it manually, the user starts this process by performing a predetermined operation from the operation unit.

  When the digital card viewer in the present embodiment receives such a card holder template acquisition instruction (S41, Yes), the URL of the template is confirmed by the card management table 330 (or directly from the MM file), and Template data is downloaded from the URL via the communication network 27 (FIG. 1) (S42). After the download is completed, the template management table 331 (FIG. 9) is updated so as to newly register the management information of the new template data (S43).

  Although not shown, when the user deletes the template in the terminal, the data is deleted from the template data storage unit 322 and the management information is deleted (or invalidated) from the template management table 331.

  As described above, according to the present embodiment, when a new digital card is acquired by data broadcasting or the like, a dedicated card holder template can be acquired based on the information specified in the MM file. . Since the card holder template can be realized with a markup language such as BML and a script, it is only necessary to have a browser and script execution environment. Therefore, the card provider does not need to install a dedicated application in advance on the mobile terminal 20, and does not necessarily provide the dedicated application. In addition, since templates described in BML and scripts can be easily created and modified, the functions of the card holder template can be easily improved, and new services can be easily provided to viewers. Is possible.

  Furthermore, if the template is described in BML, a digital card can be handled by a mobile card provider (installed with a BML browser) that supports data broadcasting services such as one-segment broadcasting. File) and templates. At the same time, the terminal manufacturer only needs to store the common viewer template in the storage medium other than the data broadcasting application, and there is no need to install a dedicated application on the mobile terminal. There is almost no cost. (Note that, as described above, even the common viewer template can be installed after the terminal is shipped.) Of course, the mobile terminal 20 has a dual browser that supports both BML and other markup languages. Needless to say.

(First modification)
In the above description, the picture of the digital card is handled as an integral image data as an image including not only an image but also characters included in the card. However, the larger the size of the digital card data, the longer the time required for distribution for one digital card. In addition, the amount of memory occupied in the terminal becomes large, and the number of digital cards that can be stored particularly in an information terminal such as a mobile terminal is remarkably limited. Therefore, the present inventors have prepared many trading cards and coupons with data common to all cards (for example, common text such as design, format and series name, trader name, etc.) and information unique to each card ( For example, paying attention to the fact that it can be divided into character images, product images or barcodes, two-dimensional code images, and unique text such as characters, product descriptions, serial numbers, prices, etc., information unique to each card is stored in the MM file It was possible to deliver data at any time on the broadcast side using a data broadcasting service, while providing information common to the card separately as a template for card display and merging them on the terminal. . Hereinafter, as a modification of the present embodiment, the configuration and operation of a card display template that provides a common portion for each card type will be described.

(Card display template)
First, FIG. 13 illustrates the configuration of the card display template 500. Such a card display template is different for each card type. In this figure, an example of a professional baseball card is shown as the card type. The card display template 500 includes a background 501 (color, pattern, pattern, etc., not shown) that is a common image for digital cards of the same card type, a name “professional baseball card” 502 that is common text data, and common items. Name “player data” 508, “batting rate” 509, “birthday” 510, and “nickname” 511 are included. Also included are image position information 504 in which unique images in the MM file are arranged, and text position information 503, 504, 505, 506, and 507 in which unique texts are arranged. In the figure, the position information is schematically shown by a broken line frame. However, in actuality, data that can specify the position and size of the broken line frame (for example, reference position coordinates such as the upper left corner and vertical and horizontal sizes, or diagonal point position coordinates). ). Information of different cards in the same type of card is stored in the broken line frame portion in the figure. Therefore, the MM file includes text data together with image data. Data that is fixedly described in the template 500 need not be included in the MM file. The template 500 can be updated by obtaining the latest one via data broadcasting or a network.

  With the use of the card display template 500 as shown in FIG. 13, as shown in FIG. 14, the image block 403 of the MM file 400 defining the digital card data has a small size corresponding only to the actual image portion. The image data 412 is stored. Further, the expansion card data 414 is compared with the expansion card data 413 (FIG. 4), the text data stored in the broken line frame of FIG. 13 and the information of the card display template URL indicating the source of the card display template. Is stored.

  By using such a card display template, the size of the image data 412 in FIG. 14 is correspondingly reduced compared to the image data 411 in which the entire card in FIG. 4 has an image size. The size is reduced. Thereby, the amount of distribution data and the amount of stored data can be reduced.

  FIG. 15 is a flowchart showing an example of processing when individual digital cards are displayed when the card display template of FIG. 13 is used.

  First, the card type of the digital card to be displayed is confirmed (S51). This can be confirmed from the card management table 330. It is also possible to confirm directly from the MM file. A card display template of the confirmed card type is acquired (S52). That is, if the card display template exists in the flash memory, it is used. If it does not exist, the card display template URL included in the expansion card data 414 is accessed and obtained via the communication network 27. Thereafter, in accordance with the card display template, necessary data items in the expansion card data 414 are read out and inserted into the card display template to configure the card contents, and the digital card is displayed (S53).

  According to this modification, the same digital card data can have different appearances by updating the card display template. Therefore, not only the digital card data but also the card display template itself has value and can be collected.

(Second modification example of acquiring MM file by communication)
In the system of FIG. 1, digital card data is distributed by broadcasting. However, in broadcasting, it is also possible to distribute information for acquiring digital card data, and acquire the digital card data from a server by communication based on the information on the mobile terminal side that has received the information.

  FIG. 17 shows a system configuration of such a modification. Also in this system, it is possible to adopt a system in which the accounting server and the authentication server shown in FIG. 16 are added. The system of FIG. 17 is different from the system of FIG. 1 in that the digital card data itself is not distributed from the broadcasting station 40 but the distribution source information is provided by broadcasting, and the mobile terminal 20 follows the user instruction to distribute the distribution source. The digital card data is downloaded from the template server 30 via the communication network 27 based on the information.

  FIG. 18 shows a processing example when the digital card viewer in the system of FIG. 17 obtains a digital card accompanying data broadcasting. The steps are the same as those shown in FIG. 10, except that steps S11 and S15 in FIG. 10 are changed to steps S11a and S15a, respectively. In step S11a, the received content data is not digital card data but its distribution source information. In step 15a, the digital card data is acquired by communication and stored. In this specification, “digital card data” and “distributor information” are collectively referred to as “card information”.

  The preferred embodiments of the present invention have been described above, but various modifications and changes other than those mentioned above can be made.

  For example, the present invention is not limited to one-segment broadcasting, but is applicable not only to terrestrial digital broadcasting, BS digital broadcasting, and CS digital broadcasting, but also to IP television broadcasting using the Internet backbone network and / or wireless LAN network. Can also be applied.

  Needless to say, the present invention can be applied not only to television but also to radio broadcasting including FM text broadcasting. All broadcasts to which the present invention can be applied are included in data broadcasts.

  Although the template is described in BML as an example, any markup language supported by the browser installed in the mobile terminal may be used. A markup language standardized by a standardization organization may be independently extended. Furthermore, it may be created in a completely unique markup language.

  Examples of the digital card of the present invention include, but are not limited to, trading cards, battle game cards, coupons, discount tickets, and the like.

  Examples of the MM file include an image file such as JPEG and GIF, and a moving image file such as animation GIF and MPEG, but are not limited thereto. For example, a unique format may be used. The MM file may be composed of sound information (music or voice) and text information. The MM file may be a combination of image information, text information, and sound information.

  Although an example in which template data is provided via a communication network has been shown, it may be provided by data broadcasting. At this time, another user interface (not shown) for inviting the storage of the card holder template suitable for the digital card is adjacent to the user interface (button 82) for inviting the storage of the digital card data as described in FIG. ) May be displayed.

  Filtering and actions corresponding to the template are defined by “extension script”, but it is also possible to define the markup language as an extension tag and interpret it by a browser.

  In the above embodiment, as an example of acquiring a template by communication via the communication network 27, the case where the template distribution URL is included as expansion card data in the MM file has been described. However, a specific template management server is always used. If templates are managed collectively (not shown) and templates are provided in response to a request from the mobile terminal 20, the template distribution URL in the expansion card data is not necessarily required. In this case, the URL of the template management server is stored, for example, in the viewer module 306 in the mobile terminal 20 in advance or by user setting. The mobile terminal 20 transmits a template request together with the card type in the expansion card data to the template management server, and the template management server returns a template corresponding to the card type in response to this request. As a result, a template corresponding to the card type can be obtained from one acquired digital card and used for handling the card such as digital card display and filtering.

  The present invention is suitable for application to mobile terminals, but does not exclude application to non-portable terminals.

  The present invention can be used in a method and apparatus for performing data processing, data broadcasting, data communication, and display processing for handling digital card data.
