Description

  The present invention relates to a technical field such as an apparatus or method for providing content data to a terminal device (client terminal) connected via a network such as the Internet, and in particular, content to terminal devices having various configurations via a network. The present invention relates to a technology that provides convenience to a user while providing data.

  Conventionally, for example, video, image, audio, character data, etc. are transmitted 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) content data are widely known. On the terminal device side, the provided content data and the like are presented by using, for example, a WEB browser installed on the terminal device, whereby the user can browse and view the desired content on the PC. can do.

  In recent years, as disclosed in Patent Document 1, not only PCs but also mobile terminals such as mobile phones and PDAs (Personal Digital Assistants) connect to server devices on the Internet to provide content data. It is possible to receive. 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 their types are different. Further, even in the same type of terminal device (for example, PC), the screen resolution may differ depending on the display used. In addition, when a user views content on a large screen display (monitor) such as a television having an Internet connection function, a television connected to an STB, or a PC connected to a large screen monitor, a predetermined distance ( For example, a usage mode in which viewing is performed at a position 3 m) away and operation is performed using a remote controller is conceivable.

  However, conventionally, content data provided by a server device such as a WEB server has been provided with content data having the same display format regardless of the type of terminal device and the difference in screen resolution (display screen size). There is a problem that the provided content data cannot be displayed properly depending on the screen resolution of the apparatus. For example, when the provided content data is created assuming a resolution of 800 × 600 pixels, a terminal device having a screen resolution of 640 × 480 pixels cannot display the entire content at once. On the other hand, although a terminal device with a screen resolution of 1280 × 1024 pixels can display the entire content at a time, the content is displayed small, so that visual balance, visibility, and the like may deteriorate.

  One example of a countermeasure for such a problem (that is, a problem of incompatibility with a terminal device) is to produce (produce) separate content data for various types of terminal devices, and to the server device for each type of terminal device. There is a method to prepare content data separately. For example, in Patent Document 2, the display function information of the terminal device is acquired and redirected to a URL corresponding to the display function, or the page image data insertion URL is dynamically selected to solve the nonconformity to the terminal device. is doing. As a method of acquiring the display function information of this terminal device, there is a method of acquiring from the item of a user agent (User Agent) in a request header of HTTP (HyperText Transfer Protocol), but in Patent Document 2, it is further referred to as a snoop agent. A small program is downloaded to the terminal device, and display function information and the like are acquired by the small program.

Another example of a countermeasure for the problem of incompatibility with the terminal device is a method of preparing a reference content and applying different conversion rules according to the type of the terminal device. For example, in Patent Document 3, a batch file serving as a conversion rule according to the type of terminal device is prepared separately from the content.
JP 2003-110748 A Japanese Patent No. 3184802 Japanese Patent No. 2002-132646

  However, in the conventional method, it is necessary to prepare a plurality of options (for example, batch files, etc.) in advance, and the server device that distributes content data has a huge production load as the types and types of terminal devices increase. And there is a problem that costs increase.

  In addition, in order for the user to view the content at a position away from the display by a predetermined distance (for example, 3 m), the constituent elements of the individual content such as fonts and image sizes are viewed away from the display. Having a sufficient size is necessary to provide easy-to-read content.

  In recent years, there has been a movement toward a ubiquitous network that provides an environment where various types of terminal devices can be connected to a network anytime and anywhere under the above-mentioned environment. Accordingly, it is assumed that terminal devices are used properly (for example, PC and PDA).

  However, when content data is provided by various types of terminal devices, content that has been browsed or viewed on one terminal device (for example, a PC) may continue to be viewed on another terminal device (for example, a PDA). Because there is no continuity (continuity), there is a problem that it is necessary to browse again from the beginning.

  Further, when the user wants to view (view) a part of the content again later, for example, the bookmark function of the WEB browser is used, and the URL (Uniform Resource Locator) of the WEB site that the user wants to view later is listed in the URL list. It is also possible to easily access the content using the URL list later, but it is difficult to maintain continuity (continuity) across a plurality of terminal devices. Although it is possible to leave a browsing history on the terminal device side by Cookie, it is difficult to maintain continuity (continuity) across a plurality of terminal devices in this case as well.

  Further, the acquisition of the display function information by the small program called the snoop agent described above is performed when the acquisition by the user agent fails, but when the acquisition by the user agent fails, the category (type) information of the terminal device is obtained. Even if the snoop agent is downloaded to the terminal device in this state, there is a possibility that the snoop agent is not suitable for the type of the terminal device, and there is a high possibility that accurate information acquisition will fail. For example, even if a small program is sent to a terminal device without knowing whether the terminal device is a PC or a PDA, the terminal device attempts to acquire information using the small program for PC and fails despite the PDA. It is likely that it will happen.

  The present invention has been made in view of the above problems, and reduces the burden and cost required for content maintenance without preparing separate contents and options according to the characteristics and capabilities of the terminal device.

By executing the stored information presentation processing program of the present invention, the session management unit 21a, the terminal information acquisition unit 21b as the terminal information acquisition unit of the present invention, the history information storage unit 21c as the history information storage unit, It functions as a content composition unit 21d as a structured data acquisition unit and a presentation format adjustment unit, and a content presentation unit 21e as a presentation unit.

  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 an authentication database (DB) 22a that stores and registers (registers) user information such as user IDs and passwords uniquely assigned to each user for each user. A history information database (DB) 22b that stores history information indicating a presentation history for each user, structured data of each content, and entity data specified in the structured data (for example, image data, video data, audio data) Etc.), a content database (DB) 22c is stored.

  The session management unit 21a is configured to manage login processing (authentication processing) using the authentication database 22a and the communication session after login.

  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 3, 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 history information storage unit 21c distinguishes history information (for example, including the above-described state holding ID and the reception time thereof) for each user (for example, associates with a user ID). In the history information database 22b. This history information is acquired from the terminal device 1 at an arbitrary timing, for example, at the time of data communication between the terminal device 1 and the server device 2 or when the communication session ends.

  The content composition unit 21d acquires (extracts) structured data corresponding to a certain page from the content database 22c, and based on the terminal information acquired by the terminal information acquisition unit 21b, the material defined in the acquired structured data The data presentation format is adjusted to a presentation format suitable for the terminal device 1. Here, the structured data acquired immediately after login is structured data corresponding to the page presented last time (presented at the end of the previous session), and the content composition unit 21d stores the structured data in the history. The information is acquired based on the latest state holding ID (recent reception time) among the state holding IDs stored in association with the user ID of the user of the terminal device 1 in the information database 22b. Thereafter, structured data corresponding to the page specified by the user of the terminal device 1 is acquired.

  Then, the content configuration unit 21d converts the format of the structured data whose presentation format is adjusted, and generates page data to be 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).

  3A to 3E are conceptual diagrams illustrating an example of a processing flow in the content configuration unit 21d. As shown in FIG. 3A, 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 FIGS. 3B and 3C, the presentation format of the material data 61 to 65 defined in the obtained structured data of “page1” 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. X500 (height (vertical direction)) pixels "is changed (reduced) from" 600 (width) x 400 (height) pixels (px) "and the material data 63 The area on the display screen on which the (image) is to be displayed is “400 (width) × 200 (height pixels) to“ 300 (width) × 150 (height) ”. The presentation format has been adjusted to be changed (reduced) to “pixel (px)”. Furthermore, the presentation format is adjusted so that the material data 62 and 64 with low priority (here priority = 2) are deleted.

  As shown in FIGS. 3D and 3E, the portion corresponding to the content of the material data defined in the structured data described in XML is described in XHTML and corresponds to the presentation format of the material data. Format conversion is performed so that the portion is described in CSS.

  FIG. 4 is a diagram showing an example of structured data actually described in XML. 5 is a description example of the presentation format description unit 52a in FIG. 4, FIG. 6 is a description example of the presentation format constraint description unit 52b in FIG. 4, and FIG. 7 is a diagram of the presentation content description unit 52c in FIG. It is a figure which shows a description example, respectively.

  As shown in FIG. 4, 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. 4, the layout layer 52 (corresponding to “page1” in this example) is provided with a presentation format description section 52a, a presentation format constraint description section 52b, and a presentation content description section 52c. . The presentation format description section 52a, the presentation format constraint description section 52b, and the presentation content description section 52c divide each material data by <div> to form 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.

  The presentation format description section 52a defines the presentation format of each material data constituting the page data. For example, the reference numeral 71 shown in FIG. 5 defines the height (height), width (width), and background color of the entire page (wrapper) on the display screen. The height (height), width (width), position from the left end (padding-left), position from the top end (padding-top), and background color are specified. In the reference numeral 73, the font size (font-size) and font (font-weight) of the character (p) displayed in the area of the content header portion are defined. Although illustration is omitted, in addition to this, various presentation formats of material data to be presented on the page are defined.

  The presentation format constraint description section 52b defines the constraint conditions of each material data, the priority information of each material data, the annotations, and the like when adjusting to the presentation format. 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”).

  The contents described in the presentation format description unit 52a and the presentation format constraint description unit 52b are interpreted by the content configuration unit 21d and adjusted to a (suitable) presentation format suitable for the terminal device 1 that has requested the page data. After that, it is finally described in CSS.

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

  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).

  Also, as shown in FIGS. 5 and 6, when the presentation format constraint description unit 52b includes the contents described in the presentation format description unit 52a, from <page_stylesheet type = "text / css"> shown in FIG. The description up to / page_stylesheet> may be omitted (in this case, the CSS can be generated without the description of the presentation format description section 52a).

  In the presentation content description part 52c, 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.

  Structured data is described in XML, and the presentation format and its constraint conditions are defined in the presentation format description section 52a and the presentation format constraint description section 52b as described above, and the presentation content is separated into the presentation content description section 52c. By doing this, it is possible to facilitate adjustment (adaptation) of the presentation format. In addition, as shown in the presentation format description section 52a and the presentation format constraint description section 52b, it is possible to perform adjustment (adaptation) more efficiently by redefining the style sheet that defines the presentation format in XML.

  The content presentation unit 21e 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 3. The page data is presented to the user in the adjusted presentation format.

[2. Operation of information presentation system]
Next, with reference to FIG. 9 thru | or FIG. 13, etc., the operation example of the information presentation system which concerns on this embodiment is demonstrated.

  FIG. 9 is a sequence diagram illustrating an example of processing and data exchange between the terminal device 1 and the server device 2, and FIGS. 10 to 12 are flowcharts illustrating an example of page data generation processing in the server device 2. FIG. 13A shows an example of a page displayed on the display unit of the terminal device 1 that is a PC, and FIG. 13B shows an example of a page displayed on the display unit of the terminal device 1 that is a PDA. It is a figure shown, respectively.

  In the following description, the user has already received a page data presentation by connecting the PC as the terminal device 1 to the server apparatus 2, and the state holding ID added to the page data presented by the PC is the presentation history. Is stored (accumulated) in the history information database 22b.

  First, when the user selects, for example, a PDA as the terminal device 1 and operates (starts up) the browser software by operating the operation unit of the terminal device 1 to specify the URL of the site of the server device 2, the terminal device 1 It connects to the server device 2 via the network 3 and transmits request information (step S1).

  Next, when the server device 2 receives the request information from the terminal device 1, the server device 2 obtains information such as the OS type and the browser type from the user agent item in the request header, and uses this information to use the terminal device type ( PC or PDA) (step S2), and redirect request information is transmitted to the terminal device 1 (step S3). As a result, it is possible to prevent a situation in which the probe is sent to the terminal device 1 and the terminal device 1 fails to acquire the terminal information 1 without knowing whether the terminal device 1 is a PC or a PDA.

  Here, when the information such as the OS type and the browser type cannot be acquired from the item of the user agent, the server device 2 uses the script (for acquiring information such as the OS type and the browser type) ( For example, an HTML document in which Java (registered trademark) script is described is transmitted to the terminal device 1. As a result, the script in the HTML document is executed by the browser of the terminal device 1, and information such as the acquired OS type and browser type is transmitted to the server device 2, and the server device 2 stores the information. Used to determine the type of terminal device (PC or PDA, etc.). Thereby, the accuracy of terminal information acquisition can be further improved.

  Next, when receiving the redirect request information from the server device 2, the terminal device 1 transmits the redirect information to the probe embedded page to the server device 2 (step S4).

  Next, when receiving the redirect information from the terminal device 1, the server device 2 acquires a probe suitable for the type of the determined terminal device (step S 5), and sends the probe and login page data to the terminal device 1. (Step S6).

  Thus, when receiving the probe or the like, the terminal device 1 activates (executes) the probe and acquires terminal information of the terminal device 1 (step S7). Next, the terminal device 1 displays the login page on the display screen in the display unit and presents it to the user. The login page is provided with user ID and password input fields. When the user operates the operation unit to input his / her user ID and password in the input field and designates (presses) an execution button, the terminal device 1 receives the input user ID and password, and the acquired terminal The login request information including the information is transmitted to the server device 2 (step S8).

  Next, when the server device 2 receives the login request information from the terminal device 1, the server device 2 executes a login process (authentication process) (step S9). For example, the user ID and password included in the login request information are stored in the authentication database 22a. It is determined whether or not it is registered. If it is registered, a login is recognized and a session is created (step S10).

  Next, the server device 2 performs page data generation processing to generate page data (step S11). Details of the page data generation process will be described later. Next, the server device 2 transmits the generated page data to the terminal device 1 (step S12).

  Next, when receiving the page data from the server device 2, the terminal device 1 displays the page on the display screen in the display unit and presents it to the user (see FIG. 13B).

  Thus, when the user views and browses the information included in the presented page and operates the operation unit to select a desired page from, for example, the table of contents displayed on the page, the terminal device 1 is selected. The page request information for requesting the page (including the state holding ID added to the page) is transmitted to the server device 2 (step S13).

  Next, when receiving the page request information from the terminal device 1, the server device 2 performs page data generation processing and generates page data (step S14). Details of the page data generation process will be described later. Next, the server device 2 transmits the generated page data to the terminal device 1 (step S15). In this way, the user views and browses information included in the presented page, and if necessary, selects a desired page as described above.

  When the user ends the viewing and browsing of the content, when the user operates the operation unit to perform logout input, the terminal device 1 transmits session discard request information to the server device 2 (step S16). .

  Next, when receiving the session discard request information from the terminal device 1, the server device 2 discards the session (step S17) and transmits a top page to the terminal device 1 (step S18).

  Next, an example of page data generation processing (steps S11 and S14) performed in the flow described with reference to FIG. 9 will be specifically described with reference to FIGS.

  When the page data generation process shown in FIG. 10 is performed by the login (step S11), the server apparatus 2 uses the latest state holding ID stored in association with the user ID obtained in the session. A state holding ID (reception time closest to the present) is acquired from the history information database 22b (step S101), and the process proceeds to step S104. On the other hand, when the page data generation process shown in FIG. 10 is performed by receiving the page request information (step S14), the server device 2 acquires the state holding ID included in the page request information (step S102). The acquired state holding ID and reception time are registered (stored) in the history information database 22b in association with the user ID obtained in the session (step S103), and the process proceeds to step S104.

  In step S104, the server apparatus 2 acquires the display screen size of the terminal apparatus 1 from the terminal information included in the received login request information.

  Next, the server device 2 determines whether or not the screen of the terminal device 1 is vertically long based on the acquired display screen size (step S105). If it is not vertically long (step S105: N), the horizontally long layout is determined. Is selected (step S107), and the process proceeds to step S109. On the other hand, when the screen of the terminal device 1 is vertically long (step S105: Y), the vertically long layout is selected (step S106), preparation processing for the vertically long layout is performed (step S108), and the process proceeds to step S109. . In the case of the vertically long arrangement, there is a high possibility that the object will be deleted in the process of step S118 described later. Therefore, in the preparation process for the vertically long arrangement, an object deletion flag is set to improve the efficiency of the loop process.

  In step S109, the server device 2 determines the maximum display screen area (safety area) on the display screen of the terminal device 1. Note that the maximum display screen area is, for example, an area excluding a toolbar (an area where material data as an object is displayed).

  Next, the server device 2 acquires structured data corresponding to the acquired state holding ID (step S110). The acquired structured data is stored and saved in the session.

  Next, the server device 2 creates a DOM (Document Object Model) document tree having each material data as an object based on the acquired structured data (step S111).

  Next, the server device 2 refers to the presentation format constraint description section 52b described above (follows (scans) under the <page_stylecontrol type = "text / css"> element), and sets each object (material data). The added priority information is extracted (step S112).

  Next, in step S113 shown in FIG. 11, the server device 2 searches for all objects other than the entire page (wrapper) having the largest display area area, and information about the object (for example, identification name, id = Is temporarily stored (also referred to as id attribute).

  Next, the server device 2 rewrites the size (height and width) of the entire page (wrapper) defined in the presentation format constraint description part 52b described above with the size of the maximum display screen area (safety area) (step S114). .

  Next, the server device 2 determines whether or not the size of the entire page (wrapper) before rewriting is equal to or larger than (the same or larger than) the size of the safety area (step S114a). In the above case (step S114a: Y) The reduction process is selected, and the process proceeds to step S115.

  On the other hand, when the size of the entire page (wrapper) before rewriting is not equal to or larger than the size of the safety area (that is, in the case of the terminal device 1 having a large display screen size) (step S114a: N), the enlargement process is selected. The process proceeds to step S115a.

  In step S115, the server device 2 determines whether or not the total of the display area (height × width) of each object is smaller than the area of the entire page (wrapper). It is discriminated whether or not it fits. When it is determined that all the objects do not fit in the page (that is, when the total area of the display areas of the objects is larger than the area of the entire page (wrapper)) (step S115: N), step S116 When it is determined that it fits (that is, when the total area of the display area of each object is smaller than or equal to the area of the entire page (wrapper)) (step S115: Y), The process proceeds to step S119.

  In step S116, the server apparatus 2 determines whether or not the display area of each object can be further reduced. For example, the server device 2 sets the initial values (default) of the display area width (height) and height (height) of each object specified in the presentation format constraint description part 52b described above to a predetermined ratio (for example, 10%). If the reduced value does not become smaller than the minimum width (minimum) of the display area of each object, the display area of each object can be reduced. Determine that there is.

  When the display area of each object can be reduced (step S116: Y), the server device 2 sets the initial values of the width (width) and height (height) of the display area of each object to the reduced width ( By rewriting with the values of width and height, the size of the display area of each object is reduced (step S117), and the process returns to step S115. By repeating such processing, the display area of each object is gradually reduced (for example, the initial value is reduced by 10% until the minimum value is reached). When the size of the display area of the reduced object becomes smaller than the minimum value (minimum) by such reduction processing, the initial value is rewritten with the minimum value.

  On the other hand, if the display area of each object cannot be reduced (step S116: N), the server apparatus 2 executes the object deletion process, refers to the priority information of each extracted object, and has the lowest priority. The object (that is, “priority” having the largest value) is deleted (step S118), and the process returns to step S115. By repeating such processing, the objects are deleted in descending order of priority.

  On the other hand, in the enlargement process in step S115a, as shown in FIG. 12, the server apparatus 2 refers to the acquired terminal information to determine whether or not the terminal apparatus 1 is a 10-foot UI terminal (step S1151). When the terminal is a 10-foot UI terminal (step S1151: Y), the process proceeds to step S1152, and when the terminal is not a 10-foot UI terminal (step S1151: N), the process proceeds to step S1157.

  In step S1152, the server device 2 uses the initial values (default) of the display area width (height) and height (default) of each object defined in the presentation format constraint description unit 52b described above to display each object. When the area width (height) and height (height) are smaller than the minimum value (minimum_10feetUI) at the time of 10 feet UI terminal, the initial value is replaced with the minimum value (minimum_10feetUI). As a result, the size of the display area is the minimum necessary for viewing 10 feet away.

  Next, the server device 2 determines whether or not the total of the display area (height × width) of each object is smaller than the area of the entire page (wrapper), so that all the objects fit in the page. (Similar to step S115) (step S1153). If it is determined that all objects do not fit within the page (step S1153: N), the process proceeds to step S1154, and if it is determined that all objects fit (step S1153: Y), the process proceeds to step S1157.

  In step S1154, the server apparatus 2 executes object deletion processing, and deletes the object with the lowest priority (that is, the value of “priority” is the highest) by referring to the priority information of each extracted object. To do.

  Next, the server device 2 again determines whether or not all the objects fit within the page (similar to step S1153 above) (step S1155), and if not (step S1155: N), the object deletion process is performed. Execute, refer to the priority information of each extracted object, delete the object with the lowest priority, and return to step S1155. Such steps S1155 and S1156 are repeatedly performed until all the objects fit within the page (step S1155: Y), the process returns to FIG. 11 and proceeds to step S119.

  On the other hand, in step S1157, the server apparatus 2 determines whether or not the display area of each object can be enlarged. For example, the server device 2 enlarges the initial value (default) of the width (width) and height (height) of the display area of each object by a predetermined ratio (for example, 10%), and the enlarged value is the display of each object. If the area is not larger than the maximum width (height) and height (height) of the area, it is determined that the display area of each object can be enlarged. When the display area of each object can be enlarged (step S1157: Y), the server device 2 caches (temporarily stores) the size of the current display area of each object (step S1158). Resize the display area of each object by rewriting the initial values of the width and height of the display area of each object with the values of the expanded width and height. (Step S1159), it is determined whether or not all objects fit within the page (Step S1160). If they fit (Step S1160: Y), the process returns to Step S1157. By repeating such processing, the display area of each object is gradually enlarged (for example, the initial value is enlarged by 10% until the maximum value is reached), and accordingly, the process proceeds to step S1158. The cached value is updated. In addition, when the size of the display area of the enlarged object becomes larger than the maximum value by such enlargement processing, the initial value is rewritten with the maximum value.

  If it is determined in step S1160 that all objects do not fit within the page (that is, no further expansion is possible) (step S1160: N), the server device 2 rewrites the rewritten initial value. The data is rewritten to the immediately previous initial value (the value cached in step S1158) (step S1161), the process returns to FIG. 11, and the process proceeds to step S119.

  In step S119 shown in FIG. 11, the server apparatus 2 performs an area error absorption process. In this area error absorption processing, for example, the width of the display area of all objects having the maximum display area area (searched in step S113) among all objects excluding the entire page (wrapper) is automatically adjusted. Thus, the area estimation error is absorbed. In other words, the object in which the display area is reduced is adjusted so that it fits properly (cleanly) in the entire page (wrapper). This area error absorption process need not be performed if there is no area estimation error.

  Next, the server device 2 adjusts the DOM document tree rewritten as described above (the content rewritten in the presentation format constraint description section 52b (under the <page_stylecontrol type = "text / css"> element) is the presentation format description. Is reflected in the part 52a (under the <page_stylesheet type = "text / css"> element), and the presentation format constraint description part 52b (under the <page_stylecontrol type = "text / css"> element) is deleted) The DOM document tree is converted into an XML document (structured data whose presentation format is adjusted) (step S120).

  Then, the server apparatus 2 generates page data by converting the format of the converted XML document (structured data with the presentation format adjusted) into an XHTML document and CSS (step S121). The page data generated in this way is transmitted to the terminal device 1 as described above.

  Thus, for example, a page as shown in FIG. 13B is displayed on the display screen of the terminal device 1 that is a PDA, and the terminal device 1 that is a PC as shown in FIG. Compared to a similar page displayed on the display screen, the display area 203 of the entire page (wrapper), the display area 204 of the object of the content header (content header), and “block 2” (here, for convenience, block 2 (This represents the heading of the content displayed in this area.) The object display area 206 is reduced, and the object of “Block 1” and the object of “Block 3” are deleted. These display areas 205 and 207 are lost.

  10 to 12, the page data generation process uses the information indicating the display screen size in the terminal information to present the object presentation format defined in the structured data in accordance with the terminal device 1. Although an example in the case of adjusting to a format has been shown, the present invention is not limited to this. Configuration (such as when the speed (bps) is 1 Mbps or less) and an object such as an image having a data amount greater than or equal to a predetermined amount of objects defined in the structured data (also in this case, a presentation format constraint description part) 52b).

  In addition, the terminal information in the above embodiment is configured to be acquired by causing the terminal device 1 to execute the probe. However, as shown in the page data generation process in FIGS. When information indicating the display screen size is used, an HTML document in which a script (for example, Java (registered trademark) script) for acquiring the information is described is transmitted to the terminal device 1, and the terminal device It may be configured such that the script is acquired by executing a script in the HTML document by one browser and transmitted to the server apparatus 2. The terminal information acquired from the HTML document in which the script is described includes, for example, the CPU type, the display screen resolution (display screen size), the line speed (bps) in the network 3, and the type of software to be installed. (For example, OS type, browser software type, etc.).

  As described above, according to the above-described embodiment, structured data corresponding to the pages constituting the content is acquired (extracted), and is defined in the acquired structured data based on the terminal information of the terminal device 1. The presentation format of the object (material data) is adjusted to a (suitable) presentation format suitable for the terminal device 1, and the page data is presented to the user of the terminal device 1 in the adjusted presentation format. Therefore, it is possible to reduce the burden and cost required for content maintenance without preparing separate contents and options in accordance with the characteristics and capabilities of the terminal device 1, and to optimize the content according to the terminal device 1 (this Page data) can be presented to the user.

  In addition, the presentation format adjustment of the plurality of objects is performed by deleting any one of the objects or by reducing the area on the display screen on which the object is to be displayed. Even in a terminal device with a small screen size, the adjustment can be performed easily and efficiently.

  In addition, since the object to be deleted is an object with a relatively low priority, the important object is left, and the object with a relatively low priority is deleted and the unnecessary object is deleted, and the presentation format is adjusted. can do.

  In addition, since the presentation format of the plurality of objects can be adjusted by enlarging the area on the display screen on which the objects are to be displayed, not only the terminal device having a small display screen size but also the display screen size. Even in a terminal device having a large value, the adjustment can be performed easily and efficiently. Further, for example, even in a 10-foot UI terminal, the display area is enlarged and adjusted to the minimum size necessary for viewing away from the display screen, so that it is possible to provide easy-to-read contents in this case.

  Further, history data indicating the presentation history of page data in the terminal device 1 is accumulated for each user, and structured data corresponding to page data presented last time with reference to history information corresponding to the user to be presented Based on this, the presentation format of the object is adjusted to the presentation format suitable for the terminal device 1, so that it is seamless (continuous) across a plurality of terminal devices 1. ) Content can be used. Accordingly, for example, the user can easily view (view) the continuation of the content that was viewed by the PC as the terminal device 1 (the continuation of the page) as the terminal device 1.

  In addition, since the state holding ID is added to each page, the presentation history of the presentation information presented last time can be easily accumulated with the state holding ID, and the presentation history can be easily grasped. it can.

(Modification)
In the above embodiment, the object deleted by adjusting the presentation format is not presented to the user in the terminal device 1, but this configuration has a disadvantage that the user cannot see the deleted object.

  Therefore, in this modification, a page is presented so that the user can recognize that there is an object deleted by adjusting the presentation format (hereinafter simply referred to as “deleted object”), and the deleted object is presented. When requested, the deleted object is obtained from the structured data described above and presented to the user.

  In this case, the page displayed on the terminal device 1 which is the PDA shown in FIG. 13B is displayed as shown in FIG. In the example of FIG. 14A, the user of the terminal device 1 adjusts the presentation format from the link display of the deleted object (the object displayed in the display areas 205 and 207 in the example of FIG. 13A). It is possible to recognize that there is an object that has been deleted.

  In this link display reference destination information, a function call for switching display is set, and the deleted object identification name (part represented by id = (also referred to as id attribute), for example, “block1”) is included. It is set as an argument of the function call (for example, <a href=“switching display function (object identification name)”> object name </a>). In the link display, the object name (the part represented by name = (also referred to as the name attribute), for example, “Block 1”) set to the deleted object, or the first character string of the object is quoted. Is done. Note that the content of the deleted object (presentation content description section 52c (under the <page_body> element)) corresponding to the identification name is replaced with the reference destination information of the link display.

  When the user of the terminal device 1 selects (for example, clicks) the link display (for example, “Block 1”) by operating the operation unit (that is, when there is a request for presentation of the deleted object). ), The display switching function with the identification name of the deleted “block 1” object as an argument is called, the structured data on the server device 2 is accessed, and the object corresponding to the identification name as the argument is Acquired and embedded in the terminal device 1 in place of the reference destination information, and the object is newly displayed (that is, an object switching display) as shown in FIG. 14B, for example. Become.

  At the same time, the object of “block 2” currently displayed is deleted instead of the object of “block 1” displayed by the selection of the link display (that is, the object is deleted by being replaced with the reference destination information of this link display). Then, the link display (“Block 2”) appears as shown in FIG. The object deleted instead of this is, for example, an object having the second highest priority after the newly displayed object (priority of the newly displayed object <priority of the object deleted instead) ).

  In addition, since the communication between the terminal device 1 and the server device 2 is performed asynchronously when the object switching display is performed, it is possible to switch only the target object without transitioning (rereading) the entire page. It becomes.

  As another example, the same group information is added to each of a plurality of objects having a common display area on the display screen of the terminal device 1, and the object to be deleted instead of the above is the link You may comprise so that it may be an object to which the same group information as the object displayed by selection is added.

  FIG. 15A shows an example in which the objects “block 1” and “block 2” share the display area 301, and the objects “block 3” and “block 4” share the display area 302. Here, in the display area 301, the object of “Block 1” is currently displayed, while “Block 2” is displayed as a link. In the display area 302, the object of “Block 3” is currently displayed, while “Block 4” is displayed as a link.

  When the user of the terminal device 1 selects (for example, clicks) “block 2” displayed as a link by operating the operation unit, for example, the object switching display is performed as described above, and FIG. As shown in (B), the object of “Block 2” is displayed, and instead, the object of “Block 1” is deleted and its link is displayed (the same applies to the display area 302).

  As described above, the objects to which the same group information is added are alternately displayed in the common display area by selecting the link (in other words, the link display of “Block 1” and “Block 2” is a tab display). (In other words, one of the objects is always displayed in the display area).

  Next, specific operations in the terminal device 1 and the server device 2 performed in the modified example described above will be described.

  First, an object deletion process in the server device 2 according to the modification will be described with reference to FIG.

  FIG. 16 is a flowchart illustrating an example of object deletion processing in the server device 2 according to the modification. The object deletion process shown in FIG. 16 is performed in place of the object deletion process in steps S118 shown in FIG. 11 and steps S1154 and S1156 shown in FIG. 11, and other processes shown in FIG. 11 and FIG. Is the same as in the above-described embodiment.

  In the process shown in FIG. 11, when the display area of each object is not reducible (step S116: N), the object deletion process shown in FIG. 16 is started. Referring to the priority information, the object having the lowest priority (that is, the highest “priority” value) is specified as a deletion target, and its identification name (id attribute) is acquired (step S211).

  Next, the server apparatus 2 describes whether an object name (name attribute) is set for the identified object to be deleted (that is, a part represented by name =, for example, “block 1” is described in the DOM document tree). (Step S212), if it is set (step S212: Y), the object name of the object is acquired (step S213), and the process proceeds to step S215.

  On the other hand, when the object name is not set (step S212: N), the initial character string of the object (that is, the initial character string of the content defined in the presentation content description part 52c (under the <page_body> element)) Is obtained instead of the object name (step S214), and the process proceeds to step S215.

  In step S215, the server apparatus 2 refers to reference destination information for linking to the object to be deleted (for example, (for example, <a href=“switching display function (object identification name)”> object name </ a >)).

  Next, the server device 2 sets the identification name acquired in step S211 and the object name acquired in step S213 (or the initial character string of the object acquired in step S214) in the created reference destination information, respectively. (Incorporate) (Step S216).

  Next, the server device 2 determines whether or not a tab name (tabview attribute) as group information is set for the object to be deleted (portion represented by tabview = described later) (step S217). If yes (step S217: Y), the process proceeds to step S218. If not set (step S217: N), the process proceeds to step S220.

  In step S218, the server apparatus 2 determines the contents of the object to be deleted (the child node between <div id = ...> and </ div>) defined in the presentation content description part 52c (under the <page_body> element). Is replaced with the created reference destination information, and the process returns to step S115 shown in FIG. 11 or step S1155 shown in FIG. Thus, when the object deletion process is started again, the object with the next lowest priority becomes the deletion target, and the same process is performed.

  FIG. 17A shows a part of the presentation format constraint description part 52b and the presentation content description part 52c before the object deletion process when the tab name (tabview attribute) is not set, and FIG. A part of the presentation format constraint description part 52b and the presentation content description part 52c after the object deletion processing is shown (corresponding to the display in FIG. 14A). As shown in FIG. 17B, it is understood that the contents of the objects of “Block 1” and “Block 3” are replaced with the reference destination information by the object deletion process. Note that “JavaScript: changeText (block 1)” in the reference destination information replaced with the object of “Block 1” indicates a switching display function (object identification name) defined in Java.

  On the other hand, in step S220, the server apparatus 2 obtains the tab name of the object to be deleted (obtained as the tab display group identification name (id attribute)).

  Next, the server device 2 determines whether or not a tab display group having the same tab name as an identification name has already been created in the presentation content description part 52c (under the <page_body> element) (step S221). If not (step S221: N), the process proceeds to step S222, and if already created, the process proceeds to step S229.

  In step S222, the server apparatus 2 creates a tab display group having the tab name acquired in step S220 as an identification name (for example, created as <div id = tab name> </ div>).

  Next, the server device 2 places an ul tag (for example, <ul> </ ul>) in a child node of the created tab display group (that is, between <div id = tab name> and </ div>) (Step S223).

  Next, the server apparatus 2 arranges an li tag (list tag, for example, <li> </ li>) in a child node of the arranged ul tag (that is, arranged between <ul> and </ ul>) (Step S224).

  Next, the server apparatus 2 associates the identification name of the object to be deleted with the li tag (step S225), and displays the reference destination information in which the identification name and the object name are set in step S216 as the child of the li tag. It arrange | positions to a node (step S226).

  Next, the server apparatus 2 displays the contents of the object to be deleted (<div id =...) Defined in the presentation content description part 52c (under the <page_body> element) as a child node of the created tab display group. (Child node between and </ div>) is arranged (step S227).

  Next, the server apparatus 2 uses the content of the object to be deleted (the child node between <div id = ...> and </ div>) defined in the presentation content description part 52c (under the <page_body> element). It replaces with the created tab display group (final one in which objects to be deleted are arranged) and returns to step S115 shown in FIG. 11 or step S1155 shown in FIG.

  On the other hand, in step S229 (when a tab display group having the same tab name as an identification name has already been created), the server apparatus 2 adds a li tag (list tag, for example, as a child node of the ul tag in the tab display group). <li> </ li>).

  Next, the server device 2 associates the added li tag with the identification name of the object to be deleted (step S230), and adds the reference destination information in which the identification name and the object name are set in step S216. It arrange | positions to the child node of a li tag (step S231).

  Next, the server device 2 deletes the content of the object to be deleted defined in the presentation content description section 52c (under the <page_body> element) (step S232), and the step shown in FIG. 11 or the step shown in FIG. The process returns to S1155.

  FIG. 18A shows a part of the presentation format constraint description part 52b and the presentation content description part 52c before the object deletion process when the tab name (tabview attribute) is set, and FIG. A part of the presentation format constraint description part 52b and the presentation content description part 52c after the object deletion processing is shown (corresponding to the display in FIG. 15A). As a result of the object deletion process, as shown in FIG. 18B, “Block 1” and “Block 2” are defined as the same tab display group (identification name is “tab1”), and the contents of these objects are referred to. It can be seen that the information has been replaced with the previous information (note that the contents of the object of “Block 1” are defined in the tab display group). “Block 3” and “Block 4” are defined as the same tab display group (identification name is “tab2”), and it can be seen that the contents of these objects are replaced with reference destination information (“ The contents of the object of block 3 ″ are defined in the tab display group).

  Next, after the page data generated through the object deletion process is transmitted to the terminal device 1 and displayed, the user operates the operation unit to select (for example, click) the link display described above. This process will be described with reference to FIGS.

  FIG. 19 is a sequence diagram illustrating an example of processing and data exchange between the terminal device 1 and the server device 2 when link display is selected in the terminal device 1, and FIG. 21 is a flowchart illustrating an example of an acquisition process. FIG. 21 is a flowchart illustrating an example of a process for specifying a new object to be deleted in the server apparatus 2. FIG. 22 illustrates an example of an object display switching process in the terminal apparatus 1. It is a flowchart which shows.

  When the user of the terminal device 1 selects (for example, clicks) the above-described link display by operating the operation unit, the terminal device 1 displays the object (deleted) set in the switching display function in the reference destination information. Presentation request information of the deleted object including the identification name of the existing object (hereinafter referred to as “deleted object”) is transmitted to the server device 2 via the network 3 (step S21).

  Next, when receiving the deletion object presentation request information from the terminal device 1, the server apparatus 2 creates reply XML data (step S22), and performs a deletion object acquisition process (step S23).

  In the deletion object acquisition process, as shown in FIG. 20, the server apparatus 2 acquires structured data (or its DOM document tree) stored and saved in the session (step S301), and further, The identification name of the deletion object included in the received deletion object presentation request information is acquired. (Step S302).

  Next, the server device 2 refers to the identification name defined in the presentation content description unit 52c in the acquired structured data (follows (scans) the id attribute under the <page_body> element) (step S303). ), Identify the object corresponding to the identifier name that matches the acquired deleted object identifier name, and acquire the contents of the deleted object (child node between <div id = ...> and </ div>) (Step S304), the reply XML data is set (Step S305).

  Next, as shown in FIG. 19, the server device 2 performs a process for specifying a new object to be deleted (step S24).

  In the process of specifying the new object to be deleted, as shown in FIG. 21, the server device 2 refers to the presentation format constraint description part 52b in the acquired structured data (<page_stylecontrol type = "text / css "> traces under the element (scans)) (step S310), identifies the object corresponding to the identification name that matches the identification name of the acquired deleted object, and specifies the tab name (tabview attribute) for the deleted object Is set (step S311). If it is set (step S311: Y), the process proceeds to step S312. If it is not set (step S311: N), the process proceeds to step S314. , Respectively.

  In step S312, the server apparatus 2 acquires the tab name set as the deletion object as the identification name of the tab display group.

  Next, the server device 2 sets the acquired identification name in the reply XML data in which the deleted object is set (step S313).

  On the other hand, in step S314, the priority information of the deleted object is acquired from the presentation format constraint description part 52b in the structured data.

  Next, the server device 2 refers to the priority information added to each object defined in the presentation format constraint description part 52b in the structured data, and the object having the second highest priority after the deleted object (hereinafter, referred to as “deleted object”). ("New object to be deleted") is specified, and its identification name is acquired (step S315).

  Next, the server device 2 determines whether or not an object name (name attribute) is set for the identified new object to be deleted (step S316), and if it is set (step S316: Y), the object name of the object is acquired (step S317), and the process proceeds to step S319.

  On the other hand, when the object name is not set (step S316: N), the initial character string of the object is obtained instead of the object name (step S318), and the process proceeds to step S319.

  In step S319, the server apparatus 2 refers to reference destination information (for example, (for example, <a href=“switching display function (object identification name)”> object name <) for linking to the new object to be deleted. / a>)).

  Next, the server device 2 sets the identification name acquired in step S315 and the object name acquired in step S317 (or the initial character string of the object acquired in step S318) in the created reference destination information, respectively. (Incorporate) (Step S320).

  Next, the server device 2 sets the reference destination information in which the identification name or the like is set in the reply XML data in which the deletion object is set (step S321).

  Then, as shown in FIG. 19, the server device 2 transmits response information including the set reply XML data to the terminal device 1 (step S25).

  Next, when receiving the response information from the server device 2, the terminal device 1 starts object display switching processing (step S26).

  In the object display switching process, as shown in FIG. 22, first, the terminal device 1 determines whether or not the reference data is included (set) in the received reply XML data. If included (step S401: Y), the process proceeds to step S402. If not included (step S401: N), the process proceeds to step S406.

  In step S402, the terminal device 1 acquires reference destination information from the received reply XML data.

  Next, the terminal device 1 stores the contents (<div id = ...> and </ div>) of the object (new object to be deleted) corresponding to the identification name set in the acquired reference destination information. The child node is replaced with the reference destination information (step S403). As a result, the new object to be deleted is deleted.

  Next, the terminal device 1 acquires the deleted object from the received reply XML data (step S404), sets the content of the deleted object at the position corresponding to the deleted object identification name in the page data, The information is displayed on the display screen (step S405), and the process ends.

  Thus, the object switching display is performed.

  On the other hand, in step S406, the terminal device 1 acquires an identification name (tag name) from the received reply XML data.

  Next, the terminal device 1 selects a new deletion target object (currently displayed object) from the reference destination information arranged in the child node of the li tag in the tab display group corresponding to the acquired identification name. The reference destination information is set to be valid (step S407), and the reference information of the deleted object is set to be invalid (step S408).

  Next, the terminal device 1 acquires the deleted object from the received reply XML data (step S409), sets the content of the deleted object at the position corresponding to the identification name of the deleted object in the page data, and uses this. The information is displayed on the display screen (step S410), and the process ends.

  In this way, the object switching display is performed on the common display area in the same tab display group.

  As described above, according to the above modification, the user can recognize the object deleted by adjusting the presentation format by the link display, and can display the object deleted by the selection of the link display. it can.

  In addition, instead of displaying the deleted object, another object is deleted (switched display), so the object that should have been included in the display area of one page is changed (re-read) ) Can be displayed continuously by switching the objects in the page. In addition, since the deletion (switching display) is configured to be performed in units of objects, it does not impair the content configuration (semantic chunk).

  Furthermore, since the same group information is added to a plurality of objects having a common display area, and the objects are switched and displayed in the display area, the same group information is not added. It is possible to make the display independent of the object, and more effective display can be performed.

  Furthermore, since the data (deleted object, etc.) supplemented from the server device 2 at the time of display switching is transmitted to the terminal device 1 in the XML format, the data can be easily supplemented on the terminal device 1 side.

  In the above modification, for example, there is no other object that should be newly deleted (for example, none of the other objects can be deleted (for example, an object with priority = “0” or priority information added in the first place). In this case, the server apparatus 2 may be configured to display the object linked to the page on the page by selecting the link display.

  In the above embodiment, information indicating the operating environment of the terminal device 1 is included in the terminal information, and based on this, the server device 2 acquires structured data, and based on the terminal information of the terminal device 1, Although the presentation format of the object defined in the acquired structured data is adjusted to a presentation format suitable for (suitable for) the terminal device 1, the present invention is not limited to this. For example, the terminal device Information indicating one type (type of PC, PDA, mobile phone, etc.) is included in the terminal information, and based on the type of the terminal device 1 (for example, the presentation format constraint description unit 52b includes each type corresponding to the type. Object constraint conditions, priority information of each object, etc. are specified), and the server apparatus 2 matches the object presentation format specified in the acquired structured data with the terminal apparatus 1 (appropriate). Was) may be configured to adjust the presentation format.

  In the above embodiment, an example in which the functions of the terminal information acquisition unit, structured data acquisition unit, presentation format adjustment unit, history information storage unit, and presentation unit of the present invention are realized in the server device 2 has been described. However, the terminal device 1 may be configured to realize some or all of the functions of the terminal information acquisition unit, structured data acquisition unit, presentation format adjustment unit, history information storage unit, and presentation unit of the present invention. For example, the terminal device 1 acquires its own terminal information, acquires the structured data stored in the content database 22c from the server device 2, and acquires the acquired data based on the acquired terminal information. The object presentation format defined in the structured data is adjusted to a presentation format suitable for the terminal device 1, and page data as presentation information is presented to the user in the adjusted presentation format. May be. Further, the terminal device 1 accumulates history information (for example, a state holding ID) indicating the presentation history of the presentation information, and refers to the history information corresponding to the user to be presented as the page data that was presented last time.
