Description

  The present invention relates to an information transmission device, an information transmission system, an information provision processing program, and an information provision method for presenting content data to a terminal device connected via a network such as the Internet. The present invention relates to a technology for providing content data suitable for a screen resolution.

  Conventionally, for example, content such as video, image, audio, and character data from a server device such as a WEB server on the Internet to a terminal device such as a PC (Personal computer) connected via a public line and a provider. Network systems that provide (distribute) data are widely known. On the terminal device side, the provided content data or the like is presented using, for example, a WEB browser installed on the terminal device, and thus the user can view desired content on the PC. Can do.

  In recent years, not only PCs but also mobile terminals such as mobile phones and PDAs (Personal Digital Assistants) can connect to a server device on the Internet and receive content data. Furthermore, recently, a so-called interactive television (in this case, a terminal device including the STB and the television is connected) to which an STB (Set Top Box) which is a communication terminal for interactive multimedia communication services is connected. Is connected to a server device on the Internet from the STB, provided with content data, and can be presented on the television.

  By the way, the terminal devices often have different screen resolutions if they are of different types, and even if they are the same type of terminal device (for example, a PC), the screen resolution may differ depending on the display used. . For this reason, it is desired that appropriate content corresponding to the screen resolution of each terminal device is displayed on the screen.

  From such a viewpoint, for example, in Patent Document 1, structured data that defines a display format (including a display size) of material data constituting content is registered in a database, and is based on terminal information acquired from a terminal device. The display format specified in the structured data is adjusted to a display format suitable for the terminal device, and the structured data format in which the display format is adjusted is converted to page data in the XHTML (Extensible HyperText Markup Language) format. A technique for transmitting to a terminal device is disclosed. Japanese Patent Application Laid-Open No. 2004-228561 describes that when adjusting the display format, the size of the display area of the image data is adjusted in accordance with the image resolution included in the terminal information.

On the other hand, in Patent Document 2, when an image is requested from a mobile phone, the image conversion server determines the mobile phone model from the User Agent included in the request, and displays the requested image file on the screen. There is disclosed a technique for converting the size of an image (number of vertical and horizontal pixels) based on still image setting information set for each model.

  However, Patent Document 1 describes adjusting the display size of image data on page data to a display size that matches the screen resolution of the terminal device, but mentions conversion of the image data itself. No.

  The display size of the image data on the screen defined by the page data, that is, the number of vertical and horizontal pixels of the area where the image data is displayed has been changed, but the number of vertical and horizontal pixels of the image data itself has not been changed. The terminal device that has received the image data must display the image enlarged or reduced in accordance with the display size. However, the processing load on the terminal device increases by the processing required for the enlargement / reduction.

  Also, for example, from the viewpoint of reducing the processing capacity of the terminal device and the time required for displaying the image data, an algorithm for enlarging / reducing the image while improving the image quality is displayed on the terminal device side when displaying the page data. In many cases, it is difficult to adopt, so that the image quality deteriorates with the enlargement / reduction of the image.

  In addition, for example, when considering a case where the terminal device performs a reduced image display, the data size of the image data transmitted to the terminal device is larger than that corresponding to the information amount of the reduced image. Therefore, the communication efficiency is not good for the visible information amount of the displayed image.

  On the other hand, in the technology described in Patent Document 2, since only one image size is set for one type of mobile phone, a plurality of images and other information are arranged on one page. It is not possible to deal with a case where the size is different for each image or the size of the same image is different depending on the layout of each page, as in the case of content that has been made.

By executing the stored information provision processing program of the present invention, the session management unit 21a, the terminal information acquisition unit 21b as the terminal information acquisition unit, the structured data acquisition unit, the display regulation data request reception unit, and the display regulation A content composition unit 21c as a data generation unit, a content presentation unit 21d and an image conversion control unit as a display regulation data transmission unit, a designation information reception unit, Conversion image data transmission means, the conversion information generation unit, converting the identification information generating means, so as to function as the image control unit 21e of the storage control unit and the data size acquisition means.

  The information presentation processing program may be downloaded to a server device 2 from a predetermined server on the Internet, for example, or recorded on a recording medium such as a CD-ROM and via a drive of the recording medium. May be read by the server device 2.

  The storage unit 22 includes a user database (DB) 22a for storing (registering) the above-described user information for each user, structured data of each content, and entity data specified in the structured data A content database (DB) 22b that stores (for example, image data, video data, audio data, etc.), and an image conversion parameter database (DB) that stores conversion parameters that define conversion rules for image data provided to the terminal device 1 ) 22c etc. are constructed.

  The session management unit 21a is configured to perform login processing (authentication processing) using the user database 22a and management of the communication session after login. Further, the session management unit 21a acquires and holds the user information of the logged-in user from the user database 22a, and the user information input by the user to the input object presented to the user is added to the input object. The information is stored for each user in association with the data ID.

  The terminal information acquisition unit 21b acquires terminal information of the connected terminal device 1. For example, when the terminal device 1 is connected via the network 4, the terminal information acquisition unit 21 b distributes the probe to the terminal device 1 and acquires the terminal information acquired thereby from the terminal device 1.

  The content composition unit 21c acquires (extracts) structured data corresponding to a certain page from the content database 22b, and based on the terminal information acquired by the terminal information acquisition unit 21b, converts the description format of the structured data to the terminal device. It is converted to a description format suitable for 1.

  Moreover, the content structure part 21c adjusts the presentation format of the material data prescribed | regulated to the acquired structured data to the presentation format suitable for the said terminal device 1 based on terminal information.

  And the content structure part 21c carries out format conversion of the structured data in which the presentation format was adjusted, and produces | generates the page data as an example of the display regulation data provided to the terminal device 1. For example, structured data (after adjustment) composed of an XML document described in XML is converted into page data composed of an XHTML document described in XHTML (eXtensible HyperText Markup Language) and CSS (Cascading Style Sheets). As is well known, the page data defines the display content of the WEB page (what kind of material data is displayed) and the display layout and display size of a plurality of material data. Here, the display content is defined in the XHTML document, and the display layout and the display size are mainly defined in the CSS.

  The image control unit 21e is configured to register the conversion parameter in the image conversion parameter DB 22c based on the structured data whose presentation format is adjusted. By adjusting the presentation format by the content configuration unit 21c, the display size of the image data in the definition of the structured data (more specifically, the number of horizontal pixels (width) and the number of vertical pixels (height)) Is changed (adjusted). When the terminal device 1 displays the WEB page on the screen based on the page data converted from the structured data, the image data is displayed in the adjusted display size. The image control unit 21e converts the original image data registered in the content DB 22b to the image conversion server device 3 so as to be transmitted to the image data terminal device 1 suitable for the adjusted display size. Information used for this conversion is a conversion parameter.

  FIG. 3 is a diagram illustrating an example of information set in the conversion parameter. In the following description, image data registered in the content DB 22b is referred to as “original image data”, and converted image data (image data generated by the image conversion server device 3) is referred to as “converted image data”. May be called.

  As shown in FIG. 3, a key, a session ID, a conversion target image name (an example of image identification information), a file format, a width, a height, a file size upper limit, and a registration date / time are set in the conversion parameter.

  The key is identification information for identifying a conversion parameter, and for example, a 7-digit numerical value is set as the key.

  The session ID is an ID given to communication between the terminal device 1 and the server device 2 used by the user from when the user logs in to when the user logs out.

  The conversion target image name is the file name of the original image data constituting the WEB page requested by the terminal device 1.

  The file format is a file format of converted image data (converted image data to be generated by image conversion) (for example, JEPG (Joint Photographic Experts Group) format, GIF (Graphics Interchange Format) format, PNG (Portable Network Graphics) format Etc.). Original image data is normally registered in the content DB 22b in JPEG format, but depending on the operating environment and type of the terminal device 1, the terminal device 1 may not support screen display in JPEG format. In that case, the image conversion server device 3 converts the file format of the image data into a displayable format that the terminal device 1 supports.

  The width and height are the number of horizontal pixels and the number of vertical pixels of the converted image data. This number of vertical and horizontal pixels matches the display size of the image data after adjustment by the content composition unit 21c. The width and height may be information (for example, a display size reduction rate (or enlargement rate)) that can specify the number of vertical and horizontal pixels of the converted image data.

  The file size upper limit is an upper limit value of the file size of the converted image data. When the display size of image data is reduced, the complexity and number of colors of patterns per unit area generally increase. Therefore, when image data is simply reduced and converted, the file size of the converted image data is the display size. It may not be as small as the reduction ratio. In some cases, the file size after conversion may be larger than the file size before conversion. As a result, although the display size of the image data is reduced, the amount of communication for transmitting and receiving the image data is not reduced or increased. Therefore, based on the idea that the file size of the image data should be proportional to the display area (width x height) of the image, the file size is based on the display size of the image data before conversion and the display size of the image data after conversion. The upper limit is set.

  The registration date is the registration date when the conversion parameter is registered in the image conversion parameter DB 22c. The conversion parameter is deleted by the image control unit 21e when a certain period (for example, one day) elapses from the registered time.

  When receiving the image data request from the terminal device 1 that has received the page data, the image control unit 21e causes the image conversion server device 3 to convert the image data based on the corresponding conversion parameter. Then, the image control unit 21e transmits the converted image data to the requested terminal device 1.

  4A to 4E are conceptual diagrams illustrating an example of a processing flow in the content configuration unit 21c. As shown in FIG. 4A, in the material data 61 to 65 defined in the structured data of “page1”, “priority”, which is information indicating the priority, is any one of 0 to 2, for example. (In this embodiment, 0 is the highest priority, and the priority decreases as the value increases). Note that “priority”, which is information indicating the priority, is not limited to 0 to 2, and may be more specifically defined as 0 to 10, for example.

  Then, as shown in FIG. 4B, the structured data of “page1” is acquired, and based on the terminal information, the structured data description format, script, etc. are converted into a format, script, etc. corresponding to the terminal device 1. Converted.

  Next, as shown in FIG. 4C, the presentation format of the material data 61 to 65 defined in the structured data is adjusted based on the terminal information. In the adjustment in this example, the area on the display screen where the material data 61 (text) should be displayed is “1024 (width (horizontal direction)) in accordance with the display screen size included in the acquired terminal information. The pixel data 63 is changed (reduced) from “× 743 (height (vertical direction)) pixels” to “600 (width) × 400 (height) pixels (px)”. The area on the display screen on which (image) is to be displayed is from “400 (width) × 200 (height pixel)” to “300 (width) × 150 (height) ) Pixels (px) ", the presentation format has been adjusted. Furthermore, the presentation format is adjusted so that the material data 62 and 64 with low priority (here priority = 2) are deleted. This is because the display screen size of the terminal device is small, and when all the material data is displayed while reducing the display size, it is difficult for the user to identify the content of the material data because the material data is too small. Become. Therefore, by deleting material data having a low priority, the display size of material data having a relatively high priority is prevented from becoming too small.

  Since the display size of the image data is adjusted, conversion parameters are registered at this time.

  As shown in FIGS. 4D and 4E, the portion corresponding to the content of the material data defined in the structured data described in XML is described in XHTML, which corresponds to the presentation format of the material data. Conversion is performed so that the portion is described in CSS.

  FIG. 5 is a diagram showing an example of structured data actually described in XML. FIG. 6 is a diagram illustrating a description example of the presentation format constraint description unit 52a in FIG. 5, and FIG. 7 is a diagram illustrating a description example of the presentation content description unit 52b in FIG.

  As shown in FIG. 5, in the state holding layer 51, state holding IDs of chapters, sections, and pages are described in tags (<>) (for example, “ The state holding ID of “page1” is “001001001001”).

  As shown in FIG. 5, the layout layer 52 (corresponding to “page1” in this example) is provided with a presentation format constraint description part 52a and a presentation content description part 52b. The presentation format constraint description part 52a and the presentation content description part 52b divide each material data by <div> to have a hierarchical structure, and have the same tree structure. Each material data is given a unique identification name (a portion corresponding to a comma after “id =”). By dividing and managing material data, which is a meaningful chunk, by <div>, the content creator can easily define the content, and the server device 2 can also efficiently adjust the presentation format. it can.

  In the presentation format constraint description section 52a, the presentation format of each material data, the constraint condition of each material data in adjusting to the presentation format, the priority information of each material data, the annotation, and the like are defined. . For example, in the reference numeral 81 shown in FIG. 6, the initial value (default: 743px) of the height of the entire page (wrapper) on the display screen (default: 743px), the minimum value of the height that can be reduced (minimum: 300px), Maximum height that can be expanded (maximum: 960px), minimum height for 10-foot UI terminal (minimum_10feetUI: 450px), and initial width (default: 1024px), can be reduced The minimum width (minimum: 400px), the maximum width that can be expanded (maximum: 1280px), and the minimum width (minimum_10feetUI: 600px) for a 10-foot UI terminal are specified. Degree information (priority = "0") is specified. In addition, in part 82, the initial value (default: 40px) of the height (height) of the area of the content header (content header) portion arranged in the page, and the minimum height (minimum: 20px) that can be reduced ), Maximum height that can be expanded (maximum: 60px), and minimum height (minimum_10feetUI: 30px) for 10 feet UI terminal, and initial width (default: 1024px), reduced The minimum possible width (minimum: 400px), the maximum width that can be expanded (maximum: 1280px), and the minimum width (minimum_10feetUI: 600px) for a 10-foot UI terminal are specified. , Priority information (priority = “0”) is defined. Also, in the reference numeral 83, the initial value (default: 30pt) of the font size (font-size) of the character (p) displayed in the area of the content header (content header) portion, the minimum value of the font size that can be reduced (minimum: 21pt), the maximum font size that can be expanded (maximum: 40pt), the minimum font size (minimum_10feetUI: 25pt) for a 10-foot UI terminal, etc. are specified, and priority information (priority = ”0”).

  Although not shown in FIG. 6, the presentation format constraint description section 52a defines the display layout (display position on the WEB page) of each material data.

  The content described in the presentation format constraint description unit 52a is interpreted by the content configuration unit 21c, adjusted to a presentation format suitable for the terminal device 1 that has requested the WEB page, and finally Will be described in CSS.

  FIG. 8 is a diagram illustrating a CSS description example generated based on the contents described in the terminal information and presentation format constraint description section 52a.

  The minimum value (minimum) is referred to when the display area is reduced or the font size is reduced in the adjustment of the presentation format, and is processed so as not to be smaller than this.

  The maximum value (maximum) is referred to when the display area is enlarged or the font size is enlarged in the adjustment of the presentation format, and is processed so as not to exceed this.

  The minimum value (minimum_10feetUI) is referred to when the display area is enlarged or the font size is enlarged in the adjustment of the presentation format when the terminal device 1 is a 10-foot UI terminal. (That is, the minimum display area size necessary for viewing 10 feet away).

  In the presentation content description part 52b, the content of each material data is defined. For example, the reference numeral 91 shown in FIG. 7 defines the content (English Study Service) of the character (p) actually displayed in the area of the content header (content header) portion. It will be described in XHTML.

  The presentation content description part 52b defines the display layout of each material data. Specifically, the positional relationship of each material data on the WEB page is defined in the description order of the contents of each material data in the presentation content description section 52b.

  The structured data is described in XML, and the presentation format and its constraint conditions are specified in the presentation format constraint description section 52a and the presentation content is separated into the presentation content description section 52b as described above, thereby providing more presentation. The format can be easily adjusted (adapted). Moreover, as shown in the presentation format constraint description section 52a, adjustment (adaptation) can be performed more efficiently by redefining the style sheet that defines the presentation format in XML.

  Although not shown in FIGS. 6 to 8, for the image data, the initial value of the presentation format is defined in the presentation format constraint description section 52a, and the presentation content is defined in the presentation content description section 52b. . A presentation format including the final display size of image data (the size of the display area) is described in CSS.

  The content presentation unit 21d transmits the page data (data composed of XHTML and CSS) generated as described above to the terminal device 1 that has requested the page data via the network 4. The WEB page is presented to the user in the adjusted presentation format.

[1.1-3. Configuration and outline function of image conversion server apparatus]
Next, the configuration and outline function of the image conversion server device 3 will be described.

  The image conversion server device 3 includes an information processing unit (computer) configured by a CPU having a calculation function, a working RAM, a ROM, and the like, and a storage unit (for example, HDD, EEPROM, etc.) that stores various programs and various data. And an operation unit (for example, an operation panel) for inputting an operation instruction from the user, and a communication unit that controls a communication state with the server device 2 in cooperation with the communication unit of the server device 2. Yes.

  Examples of programs stored in the storage unit of the image conversion server device 3 include a predetermined OS and an image conversion program. The CPU of the image conversion server device 3 reads and executes the image conversion program to convert the image data according to the parameters from the image control unit 21e. Specifically, when the vertical and horizontal pixel numbers (width and height) of the converted image data are designated as parameters, the CPU of the image conversion server device 3 sets the original image data so that the number of pixels is the same. Reduction conversion or enlargement conversion is performed to generate converted image data. Further, when a file format is designated as a parameter, the CPU of the image conversion server device 3 generates converted image data in the designated file format. Further, when the file size upper limit is designated as a parameter, the CPU of the image conversion server device 3 performs image processing as necessary so that the file size of the converted image data to be generated is equal to or less than the designated file size upper limit. Adjust the compression rate or reduce the number of colors. Then, when a plurality of parameters are specified, the CPU of the image conversion server device 3 converts the image data according to the values of the parameters.

  The image quality of the converted image data by the image conversion of the image conversion server device 3 is less deteriorated than the image quality by the reduced / enlarged display of the image in the general terminal device 1, and the processing speed of the image conversion is faster.

[1.2 Operation of information presentation system]
Next, an operation example of the information presentation system S according to the present embodiment will be described with reference to FIGS.

  FIG. 9 is a sequence diagram illustrating an example of a process flow of the information presentation system S according to the first embodiment.

  First, when the user selects, for example, a PDA as the terminal device 1, operates the operation unit of the terminal device 1 to execute (activate) the browser software, and specifies the URL (Uniform Resource Locator) of the site of the server device 2. The terminal device 1 connects to the server device 2 via the network 4 (establishes a communication session) and requests a source (step S1). In response to this, the server device 2 acquires user ID input screen data (for example, page data) or the like (step S2) and transmits it to the terminal device 1 via the network 4 (step S3).

  Thus, a user ID input screen (not shown) is displayed on the display unit of the terminal device 1, and a user ID and password input field is provided on the screen. In such a display state, when the user operates the operation unit to input his / her user ID and password in the input field and designate (press) the execution button, the input user ID and password are transmitted via the network 4. It is transmitted to the server device 2 (step S4).

  The server device 2 receives the user ID and password transmitted from the terminal device 1 and executes user authentication, for example, determines whether or not the user ID and password are registered in the user database 22a (step S5). If registered, the server device 2 issues a new session ID and requests terminal information from the terminal device 1 via the network 4 (step S6). In response to such a request, the terminal device 1 activates (executes) the probe, collects terminal information of the terminal device 1 (step S7), and transmits it to the server device 2 via the network 4 (step S8).

  Thus, the server device 2 (terminal information acquisition unit 21b) receives and acquires the terminal information transmitted from the terminal device 1. Subsequently, the server device 2 (session management unit 21a) acquires the user information of the user indicated by the user ID from the user database 22a (step S9).

  Thus, the acquired terminal information and user information are temporarily stored in a RAM or the like.

  Next, the server device 2 (content configuration unit 21c) transfers structured data corresponding to a predetermined page of the content (for example, structured data on the first page of Chapter 1, Section 1) from the content database 22b to DOM (Document Object Model). ) Obtain as a tree (step S10).

  Next, based on the terminal information acquired by the terminal information acquisition unit 21b, the server device 2 (content configuration unit 21c) converts the description format of the structured data into a description format suitable for the terminal device 1 ( Step S11).

  Next, based on the terminal information acquired by the terminal information acquisition unit 21b, the server device 2 (content configuration unit 21c) changes the presentation format of the material data defined in the structured data whose description format is converted, The presentation format is adjusted to suit the terminal device 1 (step S12). Specifically, the server device 2 maintains the display layout of the material data specified by the structured data, and also changes the display size of the material data specified by the structured data to a display size that matches the screen resolution of the terminal device 1. Adjust to. At this time, the server apparatus 2 deletes the display of the material data with low priority so that the display size of the material data does not fall below the minimum value (minimum) by adjusting the display size. Thus, the server apparatus 2 adjusts the display layout of the material data as necessary.

  Next, the server device 2 (image control unit 21e) executes an image conversion parameter assigning process for registering a conversion parameter in the image conversion parameter DB 22c based on the structured data whose presentation format has been adjusted (step S13). The details of the image conversion parameter applying process will be described later.

  Next, the server device 2 (content configuration unit 21c) converts the format of the structured data whose presentation format has been adjusted, and configures page data to be transmitted to the terminal device 1 (step S14).

  And the server apparatus 2 (content presentation part 21d) transmits the comprised page data to the terminal device 1 via the network 4 (step S15).

  Based on the received page data, the terminal device 1 (browser) displays a WEB page excluding image data on the screen, and requests a URL set in the src attribute of the img element described in the XHTML document of the page data. An image data request for URL is transmitted to the server device 2 (step S16). Although details will be described later, a conversion parameter key corresponding to image data to be displayed is set in the URL set in the src attribute of the img element.

  In response to the image data request transmitted from the terminal device 1, the server device 2 (image control unit 21e) causes the image conversion server device 3 to convert the image data, and the converted image data generated thereby is transmitted to the terminal. The image conversion distribution process transmitted to the apparatus 1 is executed (step S17). By this image conversion / distribution process, the server device 2 transmits the image data converted from the requested image data to the terminal device 1 (step S18). The details of the image conversion distribution process will be described later.

  The terminal device 1 (browser) displays the received image data in a corresponding display area on the WEB page displayed on the screen. At this time, since the width and height of the image data coincide with the width and height of the display area, the terminal device 1 does not perform enlarged display or reduced display when displaying the image data.

  When the user designates a URL of another page by operating the operation unit of the terminal device 1, the terminal device 1 transmits a request for new page data in which the URL is set as the request URL to the server device 2. (Step S19). When the server device 2 receives the page data request, the server device 2 transmits the requested page data and image data to the terminal device 1 by performing the same processing as in steps S10 to S18.

  Next, an operation example of the image conversion parameter assignment process (step S13) of the server device 2 will be described.

  10 and 11 are flowcharts illustrating an example of the flow of image conversion parameter assignment processing of the server device 2 according to the first embodiment. FIG. 12 is a diagram illustrating an example of a presentation format constraint description section of certain structured data whose presentation format has been adjusted. FIG. 13 is a diagram illustrating an example of a presentation content description unit of structured data in which the presentation format is adjusted. FIG. 14 is a diagram illustrating an example of the presentation content description part after a part of the description content of the presentation content description part in FIG. 13 is rewritten.

  As shown in FIG. 12, in the presentation format constraint description portion of certain structured data whose presentation format has been adjusted, two presentation formats of image data are defined as indicated by reference numerals 101 and 102.

  Reference numeral 101 indicates that “img” is set as the id attribute of the div element, which indicates that the presentation format of the image data is defined. And "# footer.box img" is set in the name attribute of the div element. Here, “footer” after “#” indicates the id attribute value of the div element to which the presentation format defined by reference numeral 101 is applied, and “box” after “.” Is div Indicates the class attribute of the element. “#” Is a code indicating the id attribute, and “.” Is a code indicating the class attribute. The last “img” indicates that the img element is designated as an element to which the presentation format defined by the reference numeral 101 is applied. Depending on the value of this name attribute, the id element (image data of the box display part of the footer) surrounded by the div element whose id attribute is "footer" and the div element whose class attribute is "box" The presentation format defined by reference numeral 101 is applied. In the reference numeral 101, 20px, 6px, 800px, and 240px are defined as the initial height of the image data, the minimum height, the initial width, and the minimum width.

  Reference numeral 102 indicates that “mokuji” is set as the id attribute of the div element, which indicates that the presentation format of the table of contents part of the page is defined. And ".mokuji" is set in the name attribute of the div element. In other words, the presentation format defined by reference numeral 102 is applied to an element surrounded by div elements whose class attribute is “mokuji”. In the reference numeral 102, 40px, 16px, 250px, and 100px are defined as the initial value of the height of the image data, the minimum value of the height, the initial value of the width, and the minimum value of the width.

  On the other hand, as shown in FIG. 13, the presentation content description part of the certain structured data defines the presentation content of the title part of the page (the part surrounded by the div element whose id attribute is “title-area”). The code | symbol 120 which prescribes | presents the presentation content of the code | symbol 110 part to perform and the box display part (The part surrounded by the div element whose id attribute is "footer", and the div element whose class attribute is "box") Are described.

  In the reference numeral 110, an img element 111 and an img element 112 are described. In the img element 111, a class attribute and a src attribute are described. The class attribute of the img element 111 is “mokuji”. In the img element 112, an id attribute and a src attribute are described. The id attribute of the img element 112 is “link_howto”. On the other hand, an img element 121 is described in the reference numeral 120. Although the src attribute is described in the img element 121, neither the id attribute nor the class attribute is described. Note that the src attribute of each img element describes the URL of the image data to be displayed (an example of designation information).

As illustrated in FIG. 10, when the image conversion parameter assignment process is started, the image control unit 21e acquires all div elements whose id attribute is “img” from the presentation format constraint description unit in which the presentation format is adjusted. (Step S101). When a query statement for acquiring such a div is written in XPath (XML Path Language),
/ page / page_div / page_header / page_stylecontrol // div [@ id = 'img']
It becomes. For example, 101 parts are obtained from the presentation format constraint description part shown in FIG. When acquiring the div element, the image control unit 21e selects the first div element among the acquired div elements.

  Next, the image control unit 21e selects the name attribute of the selected div element, the value of the height property (property element whose name attribute is "height") (the initial value of the height), and the width property (name attribute is "width" The value of “property element” (the initial value of the width) is acquired (step S102). For example, in the example of reference numeral 101, “# footer.box img”, 20px, and 800px are acquired as the name attribute, height property, and width property.

Next, the image control unit 21e acquires all img elements corresponding to the name attribute acquired in step S102 from the presentation content description unit (step S103). For example, if the name attribute is "# footer.box img" and you write a query to get the img element,
/ page / page_div / page_body / * [@ id = 'footer'] // * [@ class = 'box'] // img
It becomes. In this example, the img element 121 is acquired from the presentation content description part shown in FIG. When acquiring the img element, the image control unit 21e selects the first img element among the acquired img elements.

  Next, the image control unit 21e determines whether or not the selected img element has an id attribute or a class attribute (step S104). At this time, if the img element has an id attribute or a class attribute (step S104: YES), the image control unit 21e processes the img element in steps S151 to S162 shown in FIG. Migrate to

  On the other hand, if the img element has neither the id attribute nor the class attribute (step S104: NO), the image control unit 21e determines the image name of the image data to be converted based on the src attribute of the img element. , Width, height, file size, and file format are acquired (step S105). Specifically, the image control unit 21e acquires the image name from the file name portion of the image data of the URL set in the src attribute. In addition, the image control unit 21e accesses the content DB 22b with the acquired image name, and acquires the file format, width, height, and file size of the image data from the meta information and file management information of the image data to be converted. .

  Next, the image control unit 21e generates a conversion parameter (step S106). Specifically, the image control unit 21e sets the session ID acquired in step S5 illustrated in FIG. 9 as the session ID of the conversion parameter. Further, the image control unit 21e sets the image name acquired in step S105 as the conversion target image name of the conversion parameter. Further, the image control unit 21e sets a file format suitable for the terminal device 1 as a conversion parameter file format based on the terminal information. Further, the image control unit 21e sets the values of the width property and height property acquired in step S102 as the width and height of the conversion parameter.

  The image control unit 21e sets the file size acquired in step S105 (the file size of the image data before conversion) to s1, and the width and height acquired in step S105 (the width and height of the image data before conversion). Are w1 and h1, and the width property value and height property value (width and height of the converted image data) acquired in step S102 are w2 and h2, and the file size upper limit S2 is obtained by the following equation.

S2 = S1 × ((w2 × h2) / (w1 × h1))
The image control unit 21e sets the obtained S2 as the file size upper limit of the conversion parameter. The image control unit 21e sets the current date and time as the conversion parameter registration date and time.

  When the conversion parameter is generated in this manner, the image control unit 21e determines whether or not a conversion parameter having the same content (excluding the key and the registration date and time) as the content of the conversion parameter is already registered in the image conversion parameter DB 22c. (Step S107). At this time, if the conversion parameter having the same content is not registered (step S107: NO), the image control unit 21e issues a new key and associates the key with the generated conversion parameter for image conversion. Register in the parameter DB 22c (step S108).

  On the other hand, when the same conversion parameter is registered (step S107: YES), the image control unit 21e acquires a set key from the already registered conversion parameter (step S107: YES). S109).

  When the process of step S108 or S109 is completed, the image control unit 21e rewrites the value of the src attribute of the selected img element with the key issued in step S108 or the key value acquired in step S109 (step S110). . For example, in the case of the img element 121, as shown in FIG. 14, the src attribute is rewritten to, for example, “GetImage? Key = 1234567”. Here, “GetImage” is the domain name of the image conversion server device 3, and “1234567” is the key value.

  When the selected img element has an id attribute or a class attribute (step S104: YES), or when the process of step S110 is completed, the image control unit 21e determines that the currently selected img element is in step S103. It is determined whether or not it is the last img element of all the acquired img elements (step S111). At this time, if the currently selected img element is not the last img element (step S111: NO), the image control unit 21e selects the next img element from the acquired img elements (step S111). S112), the process proceeds to step S104.

  On the other hand, when the currently selected img element is the last img element (step S111: YES), the image control unit 21e determines that the currently selected div element is all the div elements acquired in step S101. It is determined whether it is the last div element (step S113). At this time, if the currently selected div element is not the last div element (step S113: NO), the image control unit 21e selects the next div element from the acquired div elements (step S113). S114), the process proceeds to step S102.

On the other hand, when the currently selected div element is the last div element (step S113: YES), the image control unit 21e receives an id attribute or a class attribute from the presentation content description part as shown in FIG. All the img elements having are acquired (step S151). If you write a query to get such a div,
/ page / page_div / page_body // img [@class or @id]
It becomes. For example, the img element 111 and the img element 112 are acquired from the presentation content description part shown in FIG. When acquiring the img element, the image control unit 21e selects the first img element among the acquired img elements.

  Next, the image control unit 21e acquires the attribute value of the selected img element from the id attribute value or the class attribute value (step S152). For example, “mokuji” is acquired as the class attribute value from the img element 111, and “link_howto” is acquired as the id attribute value from the img element 112.

Next, the image control unit 21e acquires a div element corresponding to the acquired id attribute value or class attribute value from the presentation format constraint description unit (step S153). For example, when "mokuji" is acquired as the class attribute, and a query statement for acquiring a div element is described,
/ page / page_div / page_header / page_stylecontrol // div [@ id = '"+ mokuji +"']
It becomes. In this example, 102 parts are acquired from the presentation format constraint description part shown in FIG. When acquiring the div element, the image control unit 21e selects the first div element among the acquired div elements.

  Next, the image control unit 21e acquires the height property value and the width property value of the selected div element (step S154).

  Next, the image control unit 21e acquires various types of information based on the src attribute, generates conversion parameters, issues keys and registers conversion parameters or acquires keys, and rewrites src attribute values in the same manner as steps S105 to S110. Execute (Steps S155 to S160). As a result, for example, in the case of the img element 111, as shown in FIG. 14, the src attribute is rewritten to, for example, “GetImage? Key = 2345678”. In the case of the img element 112, the src attribute is rewritten to, for example, “GetImage? Key = 3456789”.

  Next, the image control unit 21e determines whether or not the currently selected img element is the last img element of all the img elements acquired in step S151 (step S161). At this time, if the currently selected img element is not the last img element (step S161: NO), the image control unit 21e selects the next img element from the acquired img elements (step S161). S162), the process proceeds to step S152.

  On the other hand, when the currently selected img element is the last img element (step S161: YES), the image control unit 21e ends the image conversion parameter provision process.

  Next, an operation example of the image conversion distribution process (step S17) of the server device 2 will be described.

  FIG. 15 is a flowchart illustrating an example of the flow of image conversion delivery processing of the server device 2 according to the first embodiment.

  When the server apparatus 2 receives the image data request, the image control unit 21e functions as a reverse proxy of the image conversion server apparatus 3 and starts an image conversion distribution process.

  First, the image control unit 21e acquires a key value from the request URL set in the image data request (step S201).

  Next, the image control unit 21e acquires a conversion parameter corresponding to the acquired key value from the image conversion parameter DB 22c (step S202).

  Next, the image control unit 21e requests the image conversion server device 3 to convert image data based on the acquired conversion parameters (step S203). Specifically, the image control unit 21e acquires the original image data specified by the conversion target image name set in the conversion parameter from the content DB 22b, inputs the original image data to the image conversion server device 3, and The file format, width, height, and file size upper limit set in the conversion parameters are input to the image conversion server device 3 as parameters. The image conversion server device 3 converts the original image data according to the input parameters, and generates converted image data.

  When the converted image data is generated, the image control unit 21e acquires the converted image data from the image conversion server device 3 (step S204). Then, the image control unit 21e transmits the acquired converted image data to the terminal device 1 (step S205), and ends the image conversion distribution process.

  As described above, according to the present embodiment, the information processing unit 21 of the server device 2 has a size that matches the screen resolution of the terminal device 1 indicated by the acquired terminal information, and the acquired structured data is By adjusting the display size of the material data defined by the structured data so that a plurality of material data is displayed on the screen of the terminal device 1 with the specified display layout, page data is generated, and a plurality of display elements are displayed. The converted image data is generated by causing the image conversion server device 3 to perform the expansion conversion or the reduction conversion of the included image data as image data having the number of vertical and horizontal pixels corresponding to the adjusted display size (height and width). When an image data request including a URL set in the src attribute of the img element included in the page data is received from the terminal device 1 that has received the page data. Transmitting the converted image data corresponding to the URL included in the image data request to the terminal device. Then, the terminal device 1 displays a plurality of material data including the converted image data on the screen with a display size adjusted according to the screen resolution of the terminal device 1 based on the page data.

  Therefore, even if page data and image data having the same display contents are not prepared in advance for each type of terminal device 1 or the operating environment, the display data has a display size suitable for the screen resolution of various terminal devices 1 and the page data. A plurality of material data can be displayed in a prescribed display layout. Further, since the number of vertical and horizontal pixels corresponding to the display size of the image data defined by the page data matches the number of vertical and horizontal pixels of the converted image data, the terminal device 1 does not have to enlarge or reduce the image. The image data can be displayed with the adjusted display layout and the adjusted display size.

  Further, the information processing unit 21 generates page data by setting information indicating the display size of the adjusted image data and image data identification information for identifying the image data in the designation information, When the page data is transmitted to the terminal device 1 and an image data request is received from the terminal device 1, the image conversion server device 3 converts the image data to be transmitted based on the URL included in the image data request. Therefore, when the page data is transmitted, but the image data request is not transmitted from the terminal device 1 for some reason, it is possible to eliminate the waste of processing by performing image conversion in advance.

  In addition, the information processing unit 21 associates a conversion parameter including the adjusted display size of the image data and the image data identification information of the image data in the storage unit 22 in association with a key for identifying the conversion parameter. When the image data request is stored and received from the terminal device 1, the image conversion server device 3 converts the image data based on the conversion parameter corresponding to the key set in the URL included in the image data request. Therefore, by making the data size of the key smaller than the data size of the conversion parameter, communication associated with the transmission of page data compared to the case where the content of the conversion parameter is set directly in the URL of the src attribute of the img attribute The amount can be reduced.

  The information processing unit 21 sets the same key as the URL of the src attribute of the img element for the conversion parameters having the same contents (image name, file format, width, height, and file upper limit). If the browser software used on the browser side has a cache function for image data or the like, the image data having the same display contents and the same number of vertical and horizontal pixels can be obtained without requesting the server device 2 for the image data. Since the image data can be displayed with the display size defined by the page data, the processing load on the information processing unit 21 and the image conversion server 3 can be reduced.

  Further, since the information processing unit 21 causes the image conversion server 3 to perform conversion so that the data size of the image data is equal to or smaller than the size of the pixel, for example, the display size of the image data is reduced. Thus, it is possible to prevent a situation where the communication amount required for transmitting the image data does not decrease as much as the display size is reduced.

  Further, even if image data in a plurality of file formats is not prepared in advance, the terminal device 1 is converted into image data in a file format that can be supported by the terminal device 1, so that the terminal device 1 cannot display the received converted image data. Can be avoided.

  In this embodiment, the conversion parameter is associated with the key and registered in the image conversion parameter DB 22c, and the key is set in the URL of the src attribute of the img element. Is set in the URL of the src attribute of the img element, and the image data request received from the terminal device 1 is set in the conversion parameter contents (image name, file format, width, height, file size upper limit). The image conversion server 3 may perform conversion based on each parameter in the included request URL. However, in this case, since the URL data size is larger than when using a key, the communication amount of page data increases accordingly.

[2. Second Embodiment]
Next, a second embodiment will be described.

  In the first embodiment described above, the server device 2 converts the image data to be transmitted when receiving the image data request from the terminal device 1 after transmitting the page data, which will be described below. In the second embodiment, image data conversion is performed when a request for page data is received from the terminal device 1 and the presentation format of structured data is adjusted.

[2.1 Server device configuration and overview functions]
First, with reference to FIG. 16, the structure and outline | summary function of the server apparatus 2a which concern on 2nd Embodiment are demonstrated.

  FIG. 16 is a diagram illustrating a schematic configuration example of the information presentation system SS according to the second embodiment.

  As illustrated in FIG. 16, the information presentation system SS according to the present embodiment includes the terminal device 1, the server device 2, and the image conversion server device 3 in the same manner as the information presentation system S according to the first embodiment. The terminal device 1 and the server device 2 can transmit and receive data to and from each other via the network 4. Further, the configuration and function of the terminal device 1 and the configuration and function of the image conversion server device 3 are the same as those in the first embodiment.

  The configuration of the server device 2a according to the present embodiment is different from the configuration of the server device 2 according to the first embodiment in that the image conversion parameter DB 22c is not constructed in the storage unit 22, and in other respects the server The configuration is the same as that of the device 2.

  In the server device 2a having such a configuration, the image control unit 21e of the information processing unit 21 causes the image conversion server 3 to convert the image data based on the structured data whose presentation format is adjusted, and the converted image data is converted. Image data (converted image data) is stored in the storage unit 22.

  Further, when receiving the image data request from the terminal device 1 that has received the page data, the image control unit 21 e acquires the corresponding converted image data from the storage unit 22 and transmits the converted image data to the terminal device 1. It has become.

  Note that the converted image data stored in the storage unit 22 is deleted by the image control unit 21e when a certain period (for example, one day) elapses from the stored time.

[2.2 Operation of information presentation system]
Next, an operation example of the information presentation system SS according to the present embodiment will be described with reference to FIGS.

  FIG. 17 is a sequence diagram illustrating an example of a processing flow of the information presentation system SS according to the second embodiment. In FIG. 17, elements similar to those in FIG. 9 are denoted by the same reference numerals.

  As shown in FIG. 17, the operations in steps S1 to S12 are the same as those in the first embodiment. After the adjustment of the presentation format of the structured data is performed in step S12, the server device 2a (image control unit 21e) converts the image data based on the structured data whose presentation format has been adjusted. Execute the image conversion control process to be performed in step 3, and specify the URL set in the src element of the img element described in the presentation content description part of the structured data and the converted image data (converted image data) The data is rewritten as follows (step S21). Details of the image conversion control process will be described later.

  Thereafter, the operations in steps S14 to S16 are the same as those in the first embodiment. In step S16, when the image data request is transmitted from the terminal device 1 to the server device 2a, the server device 2a (image control unit 21e) stores the converted image data indicated by the request URL set in the image data request. Obtained from the unit 22 (step S22), and transmits the converted image data to the terminal device 1 (step S18). The subsequent operation is the same as that in the first embodiment.

  Next, an operation example of the image conversion control process (step S21) of the server device 2a will be described.

  18 and 19 are flowcharts showing an example of the flow of the image conversion control process of the server device 2 according to the second embodiment. In the figure, the same reference numerals are used for the same elements as in FIG. 10 or FIG. It is attached. As shown in FIGS. 18 and 19, the image conversion control process partially shares the processing content with the image conversion parameter assignment process according to the first embodiment.

  As illustrated in FIG. 18, the processes in steps S101 to S105 are the same as the image conversion parameter provision process according to the first embodiment. When acquiring the image name, width, height, file size, and file format of the image data to be converted in step S105, the image control unit 21e acquires the image conversion server device based on the information acquired in steps S102 and S105. 3 is requested to convert image data (step S121). Specifically, the image control unit 21e specifies a file format suitable for the terminal device 1 as a file format to be input to the image conversion server device 3 based on the terminal information. Further, the image control unit 21e obtains the file size upper limit value as in step S106 shown in FIG. Then, the image control unit 21e acquires the original image data specified by the image name acquired in S105 from the content DB 22b, inputs the original image data to the image conversion server device 3, and specifies the specified file format, step S102. The width property and height property acquired in step S3 and the obtained file size upper limit value are input to the image conversion server device 3 as parameters. The image conversion server device 3 converts the original image data according to the input parameters, and generates converted image data.

  When the converted image data is generated, the image control unit 21e acquires the converted image data from the image conversion server device 3 (step S122).

  Next, the image control unit 21e stores the acquired converted image data in the storage unit 22 with an image name (an example of converted image data identification information) different from the image name of the original image data (step S123). The image name at this time is determined so as not to overlap with the image name of the converted image data already stored.

  Next, the image control unit 21e rewrites the file name portion of the src attribute value of the selected img element with the image name of the converted image data (step S124).

  Thereafter, the processes of steps S111 to S114 and steps S151 to S155 shown in FIG. 19 are the same as the image conversion parameter applying process according to the first embodiment.

  When the image control unit 21e acquires the image name, width, height, file size, and file format of the image data to be converted in step S155, the image control unit 21e, as in steps S121 to S124, The conversion image data is acquired and stored, and the src attribute value is rewritten (steps S171 to S174). Thereafter, the processes in steps S161 and S162 are the same as the image conversion parameter applying process according to the first embodiment.

  As described above, according to the present embodiment, the information processing unit 21 causes the image conversion server device 3 to convert the image data when the structured data presentation format is adjusted, and The image data portion of the URL image data of the src attribute of the img element is rewritten with the image name of the generated converted image data, and page data is generated and transmitted to the terminal device 1. When it is received, the converted image data corresponding to the request URL included in the image data request report is acquired and transmitted to the terminal device 1.

  Therefore, even if page data and image data having the same display contents are not prepared in advance for each type of terminal device 1 or the operating environment, the display data has a display size suitable for the screen resolution of various terminal devices 1 and the page data. A plurality of material data can be displayed in a prescribed display layout. Further, since the number of vertical and horizontal pixels corresponding to the display size of the image data defined by the page data matches the number of vertical and horizontal pixels of the converted image data, the terminal device 1 displays the image data at the specified display size. Therefore, it is not necessary to enlarge or reduce the image.

  In each of the embodiments described above, XHTML is used as a description language for page data. However, for example, HTML may be used. Further, the display layout and display size of a plurality of material data may be defined directly in an HTML document, for example.

  In each of the above embodiments, the display size of the image data is defined by the page data (CSS). However, the display size of the image data transmitted from the server device 2 matches the adjusted display size. Therefore, the terminal device 1 does not have a problem even if the image is displayed without being enlarged or reduced. Therefore, the display size of the image data may not be defined by the page data.

  Further, in each of the above embodiments, the URL is applied as the instruction information. However, for example, a URN (Uniform Resource Name) may be applied.

  In each of the above embodiments, the image conversion server device 3 is provided outside the server device 2, but the image conversion server device 3 may be built in the server device 2. Instead of providing the image conversion server device 3, a program for realizing the image conversion function of the image conversion server device 3 is stored in the storage unit 22, and the information processing unit 21 of the server device 2 reads the program. By executing this, image conversion may be performed.

  Further, the method for acquiring the terminal information is not based on the probe described above, but may be acquired from, for example, a User Agent included in the request from the terminal device 1.
