Description

  The present invention relates to an information distribution system for distributing information to users using a computer network such as the Internet.

  An information distribution system using a computer network is widely known by WWW (World Wide Web) on the Internet. The web page is described in a program language such as HTML or XML, for example, and a browser program installed in the user terminal interprets these languages and displays a screen on the display of the user terminal. Web pages are often designed for personal computers to which a display with a relatively large display capacity is connected. When such a page is accessed using a PDA (Personal Digital Assistant) or a mobile phone with a small display capacity, The problem is that it is difficult to read. For this reason, conventionally, a method has been adopted in which a plurality of pages that provide the same information (content) are prepared in accordance with the display capacity of the terminal and are published at different URLs. The user selects and accesses a URL suitable for the display capacity of his / her terminal from a plurality of presented URLs, and browses the content from the page.

  Further, in Patent Document 1, in a network environment in which data communication is possible between a server and an information terminal having a display device or an input device, an extended description is given to content written in a description language on the server, A system that performs processing such as content optimization according to the display screen size on the information terminal side by performing processing according to the description content on the information terminal side is disclosed.

JP 2002-063155 A paragraph 0019

  However, as in the prior art described above, if a plurality of pages are prepared for the same content corresponding to the display capacity of the user terminal, there is a problem that the production cost is high and the user also has to select a URL. there were. In addition, when performing optimization processing on the terminal side as in Patent Document 1, it is not necessary to prepare a plurality of pages for the same content. For example, in a terminal having a small screen, it is not displayed by optimization. It is necessary to download all data including the data of the object, which causes a problem that communication data increases and responsiveness deteriorates.

  The present invention has been made in view of the above-described problems, and its problem is to display without preparing a plurality of web pages according to display capacity in advance and without deteriorating terminal responsiveness. An object of the present invention is to provide an information distribution system capable of distributing easy-to-see information on the displays of various user terminals having different capacities.

  In order to solve the above-described problems, an information distribution system in a network service according to the present invention is provided by a CMS server that can be connected to a plurality of terminals via a network, and this CMS server is provided from each terminal by the CMS server. A display capacity detecting means for receiving the display capacity of the display screen from each terminal when the page is accessed, and a page data generating means for generating page data having a display amount corresponding to the received display capacity of each terminal; And transmitting means for transmitting the created page data to each terminal.

  The display capacity detecting means receives the changed display capacity when the display capacity of each terminal is changed after transmitting the page data, and the page data creating means receives the page data based on the changed display capacity. Preferably, the transmission means transmits the updated page data to the terminal.

  Further, the CMS server, when accessed from the terminal, detects the display capacity of the display screen of the terminal and transmits the page data of the default display capacity embedded with a program to be transmitted to the CMS server to the terminal. Also good.

  Note that the CMS server includes a threshold value table that defines a threshold value of the display amount of page data to be created in correspondence with the display capacity of the terminal, and the page data creation means can create page data with reference to the threshold table. desirable. In this case, it is desirable that at least the upper limit of the number of characters of character data to be displayed is defined in the threshold value table according to the size of the display screen of the terminal.

  According to the information distribution system of the present invention, since the data corresponding to the display capacity can be distributed after the display capacity of the accessed terminal is detected on the server side, a plurality of web pages corresponding to the display capacity are previously stored. It is possible to provide easy-to-see information on the displays of various user terminals having different display capacities without preparation and without deteriorating terminal responsiveness. That is, on the CMS server side, the type of user terminal (personal computer, PDA, mobile phone, etc.) for viewing the display amount such as the text amount and the image amount, and the screen size of browser software operating on the personal computer (browser size) Accordingly, page data having an appropriate display amount can be sent to the terminal, whereby an easy-to-see screen corresponding to the display capacity can be displayed on each terminal.

  Embodiments of an information distribution system in a network service according to the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram schematically illustrating a configuration of a network service system including an information distribution system according to an embodiment. This system includes a CMS (Contents Management System) server 10 and a plurality of user terminals 20 connected to each other via a network N such as the Internet. The CMS server 10 is a server computer operated by a company such as a provider, and has a function of distributing various information to various user terminals 20, 30 and 40.

  The CMS server 10 includes a CPU 11, a hard disk (HD) 12 and a memory (RAM) 13 connected to the CPU 11. In the HD 12, a content DB 12a in which distributed information (content) is stored is constructed. The HD 12 receives a display capacity detection program (means) 12b that receives the display capacity of the display screen from the user terminal 20 when the user terminal 20 accesses a page provided by the CMS server 10. A page data creation program (means) 12c that creates page data with a display amount corresponding to the display capacity of each terminal based on information stored in the content DB, and a transmission program that sends the created page data to each terminal ( Means) 12d is installed. Further, the HD 12 stores a threshold table 12e that is referred to when the page data creation program 12c creates page data.

  The user terminal 20 is composed of a personal computer (PC), the user terminal 30 is composed of a PDA, and the user terminal 40 is composed of a mobile phone, and is displayed on the displays 21, 31, 41 by browser programs each incorporating information distributed from the CMS server 10. To display. In FIG. 1, the size of the PC display 21 is shown small for convenience of drawing, but actually the PC display is the largest, the PDA display 31 is the intermediate size, and the mobile phone display 41 is the smallest.

  When accessed from the user terminal 20, the CMS server 10 detects the display capacity of the display screen of the user terminal and transmits page data having a default display capacity embedded with a program to be transmitted to the CMS server 10 to the terminal. . Although the display capacity varies depending on the screen size and the character size, in the following description, the character size is assumed to be unchanged, and the description will be made focusing on the screen size represented by the number of pixels. As for the user terminal 20, on the assumption that a multi-window operating system is operating, the size of the window displayed by the browser program is regarded as the screen size, and the window size of the browser program is operated by operating the mouse or the cursor key. When is changed, it is detected that the screen size has been changed.

  Specifically, the CMS server 10 embeds a program for detecting and transmitting a screen size based on JavaScript (registered trademark) in page data corresponding to the minimum screen size described in HTML, and this is embedded in the user terminal 20. Send. JavaScript includes a function for detecting the screen size of the browser to be displayed. By using this function, the screen size of each user terminal 20, 30, 40 can be detected.

  The threshold value table 12e defines threshold values for the display amount of page data created in correspondence with the display capacity of the user terminal. FIG. 2 is an example of the threshold table 12e. Depending on the screen size (pixels) listed in the leftmost column, the number of images to be displayed on the screen, the upper limit of the title text amount (number of characters), the upper limit of the headline text amount (number of characters), the text amount of the text The upper limit of (number of characters), when the content is a product, the position and type of a purchase link, the position and type of an advertisement display, whether or not a pop-up window can be displayed, and the display position of a link to the terms of service are defined. “Maximum” in the table means that all stored character data is displayed. For the default page data described above, a value for a screen size of 120 × 120 pixels is used.

  In addition, the display capacity detection program 12b of the CMS server 10 is configured such that the browser window size is changed by an operation of a mouse or a cursor key while the provided web page is displayed on the display 21 of the user terminal 20. The change in window size is detected as a change in display capacity, the page data creation program 12c updates the page data based on the changed display capacity, and the transmission program 12d transmits the updated page data to the user terminal 20. To do.

  In the page data distributed from the CMS server 10 according to the screen size, as shown in FIG. 3, a program for detecting a change in the window size by JavaScript as an event is embedded, and when the window size is changed, This program notifies the display capacity detection program 12b of the CMS server 10 of the fact of the change. The program in FIG. 3 is an example, and the present invention is not limited to this.

  Next, the flow of information distribution using the above system will be described with reference to the flowchart shown in FIG. In this figure, the process of the user terminal 20 and the process of the CMS server 10 will be described separately. Similar processing is performed for the user terminals 30 and 40.

  When the user terminal 20 accesses a website provided by the CMS server 10 (S.1), the CMS server 10 transmits default size page data in which a program for detecting the screen size is embedded to the user terminal 20 ( S.2). The user terminal 20 displays default page data (S.3), and notifies the CMS server of the screen size (window size) by executing the embedded program (S.4).

  The page data creation program 12c of the CMS server 10 creates page data according to the screen size (S.5), and transmits the page data to the user terminal 20 (S.6). The user terminal 20 displays the transmitted page data on the display 21 (S.7).

  When the size of the window displayed by the browser program is changed during display (S.8), the change in size is notified to the CMS server 10 (S.9). The CMS server 10 updates the page data based on the notified change information (S.10), and transmits the updated page data to the user terminal 20 (S.11). The processing of steps S.7 to S.9 on the user terminal 20 side and the corresponding processing of steps S10 and S.11 on the CMS server 10 side are performed by changing the window size by the browser program on the user terminal. It is executed every time.

  By executing the above processing, page data is created on the server side according to the screen size of the display on the user terminal side (window size in the case of a PC), and this is transmitted and displayed. It is not necessary to prepare multiple different page data, and there is no need to send unnecessary data as in the case of processing on the terminal side, and it is possible to provide easy-to-view information on the display of various user terminals with different screen sizes .

  FIG. 5 shows a display example on the display of each user terminal, including registration of information in the content DB 12a omitted in the above description. When registering information (content), an input person (reporter, editor, etc.) inputs a content title, headline, and text using a content registration page as shown in FIG. By clicking the publish button after input, the input information is registered and can be viewed from the user terminal.

  The CMS server 10 creates page data suitable for the screen size of the user terminal based on the registered content based on the threshold list 12e and a template page corresponding to the screen size (the illustrated template is for PC). Thereby, even for the same content, the display on the PC display 21, the display on the PDA display 31, and the display on the mobile phone display 41 are different as shown in the figure. That is, all of the registered character information (title, headline, text), advertisements, and images are displayed on the PC display 21, and the title and text are displayed on the PDA display 31 and the mobile phone display 41. Only a part is displayed, and no headings or images are displayed. In this way, by changing the display amount according to the screen size, it is possible to display easily on any terminal.
