In the conventional WWW system, screen configuration information of a page and all information used in the page are stored in a data storage device. For this reason, for example, when using a still image of a large size or a small still image for previewing a moving image, it is necessary to create a preview image in addition to the original image.

[0007] In addition, when providing a page with a small amount of data for high-speed access in addition to a page with a large amount of data that requires time for a client to access, data for a page with a large amount of data and small data for a small amount of data are provided. You need to create each of the data for the page.

Further, for example, when replacing an original image used in a page, re-editing the screen configuration information of the page and replacing it with the screen configuration information in the data storage device, and replacing the original original image and preview image in the data storage device. It is necessary to delete the original, create a new original image and a preview image, and write it to the data storage device.

[0009] On the other hand, although there are various editing tools that support input editing of screen configuration information and various tools for image conversion and editing, it is necessary to work individually. Therefore, there is a problem that it is necessary to manage the data and to increase the data, and it is not easy to perform the above-mentioned work.

An object of the present invention is to provide screen configuration information, a still image,
An object of the present invention is to provide a data storage device having a function of automatically generating and transmitting a small data amount page in addition to a large data amount original page simply by creating and managing original data such as a moving image.

Another object of the present invention is to provide a data storage device having a function of automatically generating and transmitting a page only by creating and managing original data other than screen configuration information such as a still image and a moving image. Is to do.

[0012]

In order to achieve the above object, an information processing device (data storage device) of the present invention stores data in accordance with the content of a message received from another information processing device (for example, a client terminal). The content of the received message is checked, and if the requested data is to be converted, the data is converted and transmitted. Thus, in addition to the page composed of the original data, the page composed of the converted data can be made visible from the client terminal as if it were.

Note that the above configuration may be executed by a program stored in a storage medium or a program distributed over a network.

According to another aspect of the present invention, in addition to a processing unit for transmitting data in accordance with the content of a message received from a client terminal, the content of the message received from the client terminal is checked. If it is a request to acquire screen configuration information and the screen configuration information has not been stored at the specified address, the screen using the data in the specified address according to the information for creating the screen configuration information prepared in advance Create and send configuration information. As a result, even if there is no screen configuration information, the page can be seen from the client terminal as if it were a page.

The destination of the data storage device may be an information processing device other than the client terminal that transmitted the message. At this time, the received information may be displayed on the destination information processing device, or may be transferred from there to another information processing device (including the client terminal).
