In addition to various data used when executing each program, a work area for temporarily recording work data and the like are set. Various data stored as the browser program is executed include web page data, HTML structure conversion setting file data, and the like.

Next, the information used for converting the screen configuration of the Web page when the PDA 12 displays the Web page by the browser program will be described. FIG. 3 shows an example of the structure conversion target URL database. The structure conversion target URL database is We
URL indicating the Web page for which the screen configuration of page b is to be converted, and data indicating the structure conversion setting file used when converting the screen configuration of the Web page indicated by this URL (pointer to the HTML structure conversion setting file database) Etc. are associated and registered.

FIG. 4 shows an example of the HTML structure conversion setting file database. In the HTML structure conversion setting file database, data indicating the structure conversion setting file set in the structure conversion target URL database and the structure conversion setting file in which the content for converting the screen configuration of this Web page is set are associated and registered. To be done.
The contents set in the structure conversion setting file include, for example, screen size information, magnifications (enlargement ratios, reduction ratios) for screen components, tables / frames indicating how to convert the arrangement or arrangement of tables and frames, and the like. Information such as structure conversion guide and display / non-display setting in block units is set.

Here, a conversion example of the screen configuration of the Web page in this embodiment will be briefly described. Figure 5
(A) is an information processing device provided with a display device having a relatively large screen, such as a personal computer.
The state where page b is displayed is shown. The display screen shown in FIG. 5A shows a state in which a block A having a size across the entire horizontal direction of the display screen and three blocks B1, C1, D1 obtained by dividing the entire horizontal direction into three equal parts are displayed. There is.

6A and 6B, HTML data defining a Web page before the screen structure is converted,
The corresponding content layout is shown.

As shown in FIG. 5A, if the screen is relatively large, the entire block can be displayed on the screen even if the block has a large size in the horizontal direction.
Further, even if a plurality of blocks are arranged in the horizontal direction, they can be simultaneously displayed on one screen.

On the other hand, as shown in FIG.
When the screen of the display device is relatively small like the PDA 12, if the original Web page remains as it is, the entire block cannot be displayed for a large block such as the block A, and a plurality of blocks are arranged. Cannot be displayed at the same time. Therefore, in order to confirm the contents of each block, it becomes necessary to repeatedly perform the horizontal or vertical scroll operation.

Therefore, the PDA 12 displays the W to be displayed.
The structure conversion setting file prepared for the eb page is referred to, and the structure of the Web page is converted based on the contents of this file. For example, the whole of each block is displayed in the display screen, and a plurality of blocks are displayed. When displaying, for example, it can be displayed only by scrolling in one direction (vertical direction). 6C and 6D show an example of the converted HTML data and the converted content layout.

Next, regarding the operation in this embodiment,
This will be described with reference to the flowchart. Figure 7 shows PD
It is a flowchart for demonstrating the process which acquires the structure conversion setting file used in order to convert the screen structure of a Web page by A12.

The PDA 12 obtains a structure conversion setting file for the Web page from the service server 10 in advance in order to display the Web page after converting the layout of the screen components and the structure of the display form of the component itself. I'll do it.

For this purpose, the PDA 12 first accesses the Web page for providing the structure conversion setting file published by the service server 10, and therefore this We
Request the URL of page b through the browser program (step A1). When the service server 10 is accessed through the network 11 and a response is received from this service server 10 (step A2),
The PDA 12 notifies the acquisition request of the structure conversion setting file through the web page of the service server 10 (step A3). Here, the URL of the Web page for which the structure of the screen component is to be converted is specified.

Upon receiving the request from the PDA 12, the service server 10 searches for the structure conversion setting file corresponding to the specified URL. When the structure conversion setting file corresponding to the URL specified here is prepared, the PDA 12 is instructed to execute the file download. If the structure conversion setting file corresponding to the specified URL is not prepared, this message
Notify the PDA 12. The service server 10 is a PDA
When there is a response from 12 that the file is downloaded,
The corresponding structure conversion setting file is transmitted to the PDA 12.

When the PDA 12 acquires the structure conversion setting file from the service server 10 (step A4), the PDA 12 registers the acquired structure conversion setting file in the HTML structure conversion setting file database, and at the same time indicates any structure conversion setting file indicating this structure conversion setting file. Data (for example, F1 shown in FIG. 4) is associated and registered (step A5).

Further, the PDA 12 is a URL for structural conversion.
The URL specified in the service server 10 (the URL of the Web page whose screen structure is to be converted) and the data indicating the structure conversion setting file registered in the HTML structure conversion setting file database are registered in association with each other in the database. To do.

For example, the PDA 12 is the service server 1
0 for the URL "WWW.abc.def.com"
When a structure conversion setting file for the structure conversion setting file is requested, a structure conversion setting file having the contents shown in FIG. 4 is acquired, and the data “F1” and the URL “WWW.
abc. def. com ”as shown in FIG.

Next, the process of converting the structure of the screen constituent parts using the structure conversion setting file based on the information display program and displaying the Web page will be described with reference to the flowchart shown in FIG.

The PDA 12 requests the URL of this Web page through the browser program in order to access the Web page published by the Web server 14 (step B1), and the W server 14 requests the corresponding W.
It is assumed that the eb page data (HTML data) has been received (step B2). The data of the Web page received here has the content shown in FIG. 6A, and the data shown in FIG.
W with a layout with normal content, as shown in
It is an eb page.

The PDA 12 refers to the structure conversion target URL database (step B3), and searches whether the URL of the Web page currently displayed is registered, that is, whether the screen configuration is converted.

Here, when the URL of the Web page is not registered in the structural structure conversion target URL database (step B4), the PDA 12 displays the Web page based on the HTML data of the received Web page by the browser program. (Step B8). In this case, the user horizontally scrolls the screen to see the entire page.

On the other hand, when the URL of the Web page is registered in the structure / structure conversion target URL database (step B4), the PDA 12 has a structure registered corresponding to the URL registered in the structure / structure conversion target URL database. HTM based on the data showing the conversion setting file
The L structure conversion setting file database is searched to acquire the structure conversion setting file used for the structure conversion (step B5).

Then, the PDA 12 executes a content conversion process for converting the structure of the screen constituent parts of the Web page based on the content of the acquired structure conversion setting file (step B6).

Here, the URL "WWW.abc.de"
f. Web page of "com."
It is assumed that the structure conversion setting file corresponding to this URL has been acquired. In the structure conversion setting file, as shown in FIG. 4, screen size information, screen component reduction ratio, table / frame structure conversion guide, block unit display / non-display setting are set.

The PDA 12 executes the content conversion processing according to the contents of the structure conversion setting file as shown in the flowchart of FIG.

First, the blocks included in the Web page are reduced according to the reduction ratio set as necessary for the blocks (step C1). Here, P
The block is reduced to a predetermined size so as to fit the size of the display screen of the DA 12. For example, in FIG.
When the block A shown in (b) is a homepage title image, the image is reduced based on the reduction ratio set for this block.

Next, the arrangement order of the constituent parts whose arrangement is defined is changed using the table or frame function (step C2). In the content layout shown in FIG. 6B, the arrangement is such that block A, blocks B1, C1, D1, blocks B2, C2, D2, blocks B3, C3, D3 are displayed in this order from the top of the Web page. However, as shown in FIG. 6D, the arrangement is changed in the order of block A, block B1, block B2, ..., Block C1, ... Block D2, and block D3. In this example, the arrangement of each block is defined by lighting as shown in FIG. 6A, and a predetermined line feed tag (<TR>) is inserted according to the structure conversion guide such as the table of structure conversion information. It will be converted into HTML data as shown in FIG.

Further, display / non-display of blocks is processed (step C3). In the example shown in FIG. 6, the block B3 and the block D1 are hidden, and the description is deleted from the HTML data. For example, the block B is the We
When the block D1 is not the contents of page b and the block D1 is the link menu part to another website, it is not necessary to display these on the small screen, so the corresponding block is hidden. Information will be set as structure conversion information. Then, by deleting the data of the target block based on this information, it is possible to convert it to HTML data in which a specific block is hidden.

In this way, when the converted HTML data is generated based on the contents of the structure conversion setting file by the content conversion processing (step B7), the PDA 12 sends W based on the converted HTML data by the browser program.
The eb page is displayed (step B8).

In this way, the PD in this embodiment is
In A12, when the Web page is displayed, the structure (content layout) of the screen component parts of the Web page is converted according to the contents of the structure conversion setting file acquired in advance by the information display program.
It is possible to display a Web page that matches the display screen of the display device provided in.

For example, when the content layout is converted to that shown in FIG. 6D, one block (screen component) is displayed without horizontal scrolling as shown in FIG. 5B. Since it has been converted to, you can check all the contents that make up the page simply by scrolling the screen in the vertical direction.

In the above description, the content conversion processing program is provided separately from the browser program, but the conversion processing may be included as part of the browser program to include its processing function.

In the above description, the structure conversion setting file is described as being provided from another service server 10 different from the web server 14 that provides the web page, but the web page is provided. The existing server may individually provide the structure conversion setting file in association with the Web page.

In the above description, the structure conversion setting file used when converting the structure of the Web page in the PDA 12 is the service server 10 (or We).
b) It is supposed to be acquired from the server 14).
The structure conversion information may be created in 12 and registered as a structure conversion setting file. In this case, P
It is assumed that the DA 12 is executed by executing a structure conversion information creation program for easily creating structure conversion information indicating how to convert a plurality of screen constituent parts forming a Web page. The structure conversion information creation program creates structure conversion information according to the conversion content for each screen component specified in the Web page, registers it in the HTML structure conversion setting file database, and creates a URL indicating this Web page. The conversion target U is associated with the data indicating the structure conversion setting file.
Register in the RL database. Alternatively, the structure conversion setting file may be stored in the memory at the manufacturing stage of the PDA.
