Description

  The present invention relates to a hypertext display device, and is a technique applied to a browser for displaying hypertext data existing on the Internet WWW, an intranet, or the like.

  Among browsers for displaying hypertext information existing on the Internet WWW, intranet, etc., Microsoft Internet Explorer, Netscape Netscape Navigator, etc. are well known. In these browsers, the location where hypertext is stored is specified and the content of the hypertext is displayed. At this time, in the user interface, the user generally specifies URL information directly by keyboard input or indirectly by specifying an icon or character string indicating a link on the screen. It is.

  At present, in order to obtain a large amount of hypertext information existing on the WWW, target information is searched while following link information by using a directory service or the like.

  In addition, a technology for connecting to the Internet WWW using a small portable terminal called a mobile has been established. Since this mobile has a limited memory capacity, it has a simple function as a browser. For this reason, when connected to the Internet using a mobile, there is a restriction that, for example, image information cannot be displayed.

  The method of sequentially searching by following the link information has the problem that (1) the operation is complicated and the user needs to get used to it. In addition, (2) a lot of hypertext is accessed before reaching the target information. Therefore, especially in a low-speed connection mode using dial-up using a telephone line, the time for searching and the cost for communication are required. There is also a problem that it takes.

  Furthermore, (3) In general, hypertexts on the Internet or an intranet are associated with link information in a complex manner, and the user may be confused while following the link information. Further, when hypertext is displayed in an offline state that is not connected to the network, access to a link destination that appears there is impossible if the link destination exists on the network. In this case, the link destination address (URL or the like) must be stored or written down and accessed later. This operation is complicated and hinders smooth browsing.

  On the other hand, when connected to the Internet using a mobile, there is a restriction that image information cannot be obtained as described above. For this reason, if you want to acquire image information, you will have to access the same site again with a normal computer again. In that case, you must repeat the same operation again to access the target information. It is troublesome.

Therefore, it is possible to reduce the waiting time for connecting to a site with hypertext on the network, the effort to move between multiple sites, the communication cost, and the user gets confused while following the link information. It is a first object of the present invention to provide a hypertext display device that does not occur.

  Also, when hypertext is displayed separately from the network such as the Internet or intranet (offline display), even if there is a link to hypertext existing on the network, this link is temporarily stored. It is a second object of the present invention to provide a function that enables flexible operation such as viewing link destination information when connected to a network later and contributes to smooth WWW browsing.

  In order to solve the above problems, the present invention employs the following means.

FIG. 3 is a diagram showing a specific configuration of the table (8) of the present embodiment. Hereinafter, the hypertext display device of this embodiment will be described in detail with reference to FIGS. 2 and 3.

  In the present embodiment, the hypertext display device is realized by software (browser) on a personal computer. This software interprets the HTML data and displays a window (1) including data such as text, images, and graphics on the display screen of the personal computer. A part of the text displayed on the window (1) is identification data in which link information to other HTML data or the like is embedded, and is highlighted with an underline in FIG. Hereinafter, this identification data is expressed as link text (2)). A part of the image data is an icon (3) indicated by a bitmap in which link information to other HTML data or the like is embedded.

  Here, the link of HTML data as hypertext data in the present embodiment will be specifically described. As described above, the identification data indicating the presence of linked information in the HTML data is the icon (3), graphic, photograph, or color indicated by the bitmap among the HTML data displayed in the browser. And a link text (2) with an underline, etc., and are associated with a tag for a hypertext link (usually, an HTML hypertext-related tag is <A> and is called an anchor (錨)).

  The anchor starts with <A, specifies the document name (data name) of the hyperlink destination by the parameter “HREF =“ filename ””, and closes with a greater than symbol (>). Subsequently, a text (link text) to be displayed on the window 1 is input. Finally, the anchor tag ends with </A>.

  For example, in the entry <A HREF=“MaineStates.html”> Maine </A>, the document MainStates. A hyperlink to html is created. At this time, MainStates. The html file must be placed in the same directory as this document. If you want to place it in another directory, you can specify the relative path from this document. For example, the file NJStates. When an html document is placed in the subdirectory AtlanticStates, the following display may be performed.

  <A HREF=“AtlanticStates/NJStates.html”> NJStates </A> Also, an absolute path name can be specified instead of a relative path name, and this path name is specified differently depending on the WWW server.

  Furthermore, in the WWW, the location of HTML data stored in other WWW servers can be specified in a unified manner using an expression called Uniform Resource Locators (URLs). The URL also includes the type of resource, allowing access (protocol) to resources other than the WWW (eg, Gopher, WAIS, FTP). The URL grammar is shown below.

scheme: // host. domain [: port] / path / filename where scheme is one of the following:
file: file on the local system or on the anonymous FTP ftp: file on the anonymous FTP http: file on the World-Wide Web server gopher: file on the Gopher server WAIS: file on the WAIS server news: newsgroup telnet: by TELNET Connection to host For example, a tag for referring to an HTML file on another WWW server is specified as follows.

<A HREF = "http://www.ncsa.uiuc.edu/Gene

In the present embodiment, a specific example in the case where the hypertext display device of the first embodiment is provided with a transfer unit as described in the fifth embodiment will be described.

  The hypertext display device of this embodiment is realized by a CPU (not shown) executing a program stored in the hard disk (23) of the desktop PC (21). The desktop PC (21) is connected to the Internet (22) as a network via a data modulation device (modem) and a telephone line (not shown). A portable computer (handheld computer, hereinafter referred to as H / PC) (24) is also a hypertext display device realized by the CPU executing a program stored in the hard disk.

  The desktop PC (21) acquires HTML data from the WWW and downloads it to the hard disk (23). The desktop PC (21) and the H / PC (24) are connected to each other by a serial interface (transfer means) (26). Thereby, the data stored in each hard disk can be transferred to each other. Further, the H / PC (24) can be used by being connected to the Internet alone.

Hereinafter, the procedure in the case of using a plurality of hypertext display devices of the present embodiment will be described with reference to FIGS. First, a user starts a browser using H / PC (24), and acquires HTML data (hypertext data) via the Internet (step 201). The acquired HTML data is interpreted and displayed on the display screen of the H / PC (24) (step 202). At this time, since the hypertext is displayed in a simplified manner, image data or the like is not displayed. The user browses the displayed hypertext and designates necessary identification data (step 203). Then, information (link source address) indicating the location of the currently displayed hypertext is acquired (step 204). Further, link information (link destination address) specified by the identification data is acquired (step 205). The link destination address and the link source address are associated with each other and transmitted to the desktop PC (21) via the serial interface (26) (step 206). By such a procedure, link destination information of HTML data including a portion that cannot be displayed by the portable terminal (H / PC (24)) is secured and transmitted to a displayable computer (desktop PC (21)). be able to.

  On the other hand, the desktop PC (21) acquires link information including a link source address and a link destination address transmitted from the H / PC (24) (step 207). Then, in accordance with the acquired link information, the HTML data existing at the link source address is acquired (step 208). Next, the HTML data present at the link destination address is acquired and each HTML data is displayed (step 209).

  When an H / PC (24) equipped with a browser for simple display is used to access the Internet on the go, there may be information that cannot be displayed although HTML data is displayed. In order to view the information, the access information can be transmitted to another information processing apparatus such as the desktop PC (21) by the serial interface, and the information can be displayed by a browser capable of normal display. Therefore, the HTML data desired by the user can be displayed without repeating the same operation as that performed on the H / PC (24) on the desktop PC (21).

  Further, when the hypertext display device of the present embodiment is used, it can be used in the following manner. First, HTML data on the WWW is acquired by the desktop PC (21), and this HTML data is transferred to the H / PC (24). Then, the transferred HTML data is decoded and displayed on the H / PC (24) in an off-line state not connected to the Internet. While displaying HTML on the H / PC (24), the user designates identification information of a link desired to be viewed later. This information is stored on the H / PC (24) and transferred to the desktop PC (21) when the H / PC (24) is connected to the desktop PC (21) again. Thereby, the HTML data that could not be browsed on the H / PC (24) can be acquired and displayed by the desktop PC (21).
