Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information presenting apparatus for receiving and displaying information of a WWW server, and an information transferring apparatus for receiving data stored in the WWW server and transferring the data to the information presenting apparatus.

[0002]

2. Description of the Related Art In recent years, the Internet has been actively used, and effective use of information (homepage) stored in each site on the World Wide Web (WWW) has been attempted.

[0003] These homepages are mainly HTML
(Hyper Text Markup Langua
ge), the HTML is in a hypertext format, and a link from one document written in HTML to another HTML document can be provided. As a result, it is possible to browse through topics of interest while freely skipping through the document from the document, instead of reading the document sequentially as in a book. Note that HTML
Is described in detail in "HTML Introduction WWW Page Creation and Publication" (published by Prentice Hall Publishing Co., Ltd.).

[0004] Internet browsers have been developed as software for browsing hypertext written in HTML. The Internet browser interprets the document written in HTML and displays it on the screen. In addition, the Internet browser can display a homepage that the user wants to view by using HTTP implemented on TCP / IP.
It also has the function of acquiring by communicating with the server using the protocol.

When an Internet browser or the like displays a hypertext such as this homepage on a screen, a character string indicating a hyperlink included in the hypertext is different in color from text other than the hyperlink and is underlined. Often displayed. The user sees the displayed hypertext and knows from the character string having such a special display form that a link is provided to another page. If a page linked from this character string has already been moved, the page is displayed in a color different from the color indicating the hyperlink. As such hypertext display technology, for example, Netscape Navigator of Netscape,
There is Microsoft Internet Explorer.

In order to prevent unauthorized access to the network, a proxy server called a proxy server may be used. This is to connect the majority of clients to the internal network so that only one of them can actually interact with the WWW wide area network. This one computer acts as a proxy for requests from the WWW browser on the internal network, requests for data from the external wide area network,
Performs reception, etc.

[0007] As an example of this proxy server, UNI
There is a DeleGate that runs on X.

[0008]

By the way, in the above-mentioned conventional technology, the display of the character string indicating the hyperlink is performed by making a link from the character string to another page.
It simply indicates whether or not you have ever navigated to the linked page from that string. At present, the number of WWW users has increased rapidly, and access to the same server has been concentrated, resulting in a decrease in data transmission speed from the server and an increase in transmission time. In the above-described conventional technology, the data transmission speed of the server and the time required for transmission cannot be determined merely by looking at the character string indicating the hyperlink linked to the server. Therefore, unless the user actually follows the hyperlink and accesses the server, the server cannot know the data transmission speed and the time required for transmission. Then, an attempt was made to access the server, but it was difficult to connect to the server, or it took a long time to receive data from the server, and the user often felt uncomfortable.

In view of the above problems, according to the present invention, when displaying a certain hypertext, the attributes (data transmission time, transmission speed, data size, and data size) of the server to which the hyperlink included in the hypertext is linked. (Access count), and by changing the display format of the character string indicating the hyperlink according to the obtained attribute value and displaying it, it is possible to explicitly inform the user of the attribute of the server data. It is an object of the present invention to provide an information presenting device that can be used and an information transfer device that acquires data and an attribute of data from a server and transmits the data to the information presenting device instead of the information presenting device.

[0010]

SUMMARY OF THE INVENTION In order to solve this problem, the present invention provides a user input processing means for processing a hyperlink designation operation from a user, and hypertext data designated by the user input processing means. Hypertext data obtaining means for obtaining, hypertext data interpreting means for interpreting the hypertext data obtained by the hypertext data obtaining means, and a hyperlink included in the hypertext interpreted by the hypertext interpreting means. Link destination attribute acquisition means for acquiring the attribute of the data of the link destination, and display content generated from the hypertext interpreted by the hypertext interpretation means, at which time the link destination acquired by the link destination attribute acquisition means is generated. Table of hyperlinks by data attributes A display content generation means for changing the form,
Display means for displaying the display content generated by the display content generation means. Then, the link destination attribute obtaining means obtains the attribute of the data of the link destination and changes the display mode of the hyperlink according to the attribute of the data, so that the user can be explicitly notified of the attribute of the link destination of the hyperlink.

[0366]

According to the present invention, when displaying a certain hypertext, the attribute of the data of the server to which the hyperlink included in the hypertext is linked is acquired, and the attribute is obtained according to the obtained attribute value. By changing the display form of the character string indicating the hyperlink and displaying it, it is possible to explicitly notify the user of the attribute of the server data. This allows the user
The attributes of the server's data can be known before actually accessing the server. Therefore, when the data transmission speed of a server from which information is to be acquired is low, data can be received in a short time from another server having a high transmission speed, and the data reception time can be reduced. From the above, it is possible to improve the efficiency of data collection such as WWW.

Further, according to the present invention, when a certain hypertext is displayed, it is possible to explicitly notify the user of the size of the data of the server to which the hyperlink included in the hypertext is linked. . In the present invention, since the information presentation device or the information transfer device manages the data size of the server to which the hyperlink is linked, there is no need to manage the data size on the server side. There is no need to describe and update the data size in the hypertext in advance.

According to the present invention, when a certain hypertext is displayed, the number of accesses to the server to which the hyperlink included in the hypertext is linked can be explicitly notified to the user. Therefore, the user can know which server is popular before actually accessing the server. In the present invention, since the information presentation device or the information transfer device manages how many times the server to which the hyperlink is linked has been accessed so far, the server does not need to manage the number of accesses.
