A browsing device for browsing hypertext data containing image data as necessary to data described in Text Markup Language as a page, and a storage medium storing a browser that enables similar processing on a computer About.

[0002]

2. Description of the Related Art An example of browsing hypertext data as an HTML file in a conventional browsing apparatus and a process for browsing will be described below with reference to FIGS.

[0003] It should be noted that hypertext data is HTM
If there is a tag that incorporates image data in data described in L (Hyper Text Markup Language) or in data described in HTML, the data described in HTML and the image data are combined. Refers to composed data. A page is a file in which hypertext data is formatted for display.

As an example of browsing hypertext data with a conventional browsing apparatus, as shown in FIG. 17, for example, a Web page (page) on the Internet
An example of browsing is given.

In FIG. 17, reference numeral 1001 denotes a first page which is the top page, and reference numeral 1002 denotes a link destination information description portion (hereinafter, anchor) 1001a on the first page 1001. Indicates the second page to which a jump is made when is selected. Reference numeral 1003 denotes an anchor 1 on the second page 1002.
When 002a is selected, a third page to be a jump destination is shown.

The operation of the conventional browsing apparatus for browsing hypertext data as a page will be described with reference to FIG.

First, the browsing device acquires hypertext data from a network or a storage device of the browsing device (step S1101).

Next, the browsing device analyzes the acquired hypertext data (step S1103) and displays a page formatted for display.

Next, the browsing device checks a selection operation event (such as a mouse click operation) (step S).
1104).

Here, if the selection operation event has not occurred, the browsing device continues the process of step S1104 again. On the other hand, when a selection operation event has occurred, the browsing device determines whether the selection operation event has selected an anchor on the page (step S110).
5).

If it is determined in step S1105 that the selection operation event is not an anchor selected, the browsing apparatus further determines whether or not other processing needs to be performed (step S1107). If there is a need to perform another process, if no other process needs to be performed, the selection operation event is invalidated, and the process of step S1104 is continued.

On the other hand, if it is determined in step S1105 that the selection operation event is that of selecting an anchor, the browsing device obtains the address of the link indicated by the anchor (step S1106), and again executes step S1101. The selected hypertext data is displayed as a page by the processing from to step S1103.

When an anchor is also present in the selected hypertext data (when viewed from the user side, in a page formatted for display), if the anchor is selected by a selection operation event, the browsing device will ,
Further, the processing of displaying the hypertext data of the link destination corresponding to the anchor as a page is repeatedly performed.

[0014]

However, browsing hypertext data as a page using a conventional browsing apparatus has caused the following problems.

That is, when browsing hypertext data as a page using a conventional browsing apparatus, an anchor indicating a desired link destination is searched for from information shown on a page obtained by formatting the hypertext data. However, after specifying the anchor, the hypertext data of the desired link destination is displayed as a page.

Therefore, in order for a user to obtain necessary information with a conventional browsing device, the above-described processing needs to be repeated many times until the intended information is obtained, and the operation is complicated. Had occurred.

In addition, today, when one of the Internet services, WWW (World Wide Web), has become widespread, browsing of hypertext data (pages) has gradually penetrated into ordinary households. Beginners trying to receive it are increasing.

However, in order to efficiently browse a page (HTML file) by using a conventional browser or software such as a conventional WWW browser installed in a computer or the like, it is necessary to use “hypertext” or “hypertext”. Since it is necessary to understand the concept of "tier management", it has been difficult for beginners to use the WWW service.

Accordingly, an object of the present invention is to provide a hypertext data browsing apparatus and a hypertext data browsing method capable of reducing the burden of understanding the concept of hypertext or hierarchical management.

[0020]

It becomes as shown in.

Further, the hierarchical information list 103b obtained from the link relationship shown in FIG. 4 is as shown in FIG. As is clear from FIGS. 4 and 6, the link relationship shown in FIG. 4 corresponds to each node shown in FIG. For example, the home page 401 corresponds to the head address 501, and the link page 402 corresponds to the link address 502.

The hierarchical information list 10 shown in FIG.
Navigation information list 103c obtained from 3b
Is as shown in FIG. As can be understood from FIG. 7, the navigation information list 103c is a list in which the items (link destinations; pages) of the hierarchical information list 103b are displayed in order. Further, the navigation information list 103c when the area priority is applied as the search condition
7 is denoted by reference numeral 701 in FIG. 7, and when depth priority is applied, is denoted by reference numeral 702 in FIG. That is, in the navigation information list 103c when the breadth-first is applied, each page shown in FIG. 4 includes reference numerals 401, 402, 403, 404, and 40.
5, 406, 407,... Are displayed in the page order. In addition, in the navigation information list 103c when depth priority is applied, each page illustrated in FIG. 4 includes reference numerals 401, 402, 405, and 40.

The operation and processing in the hypertext data browsing apparatus according to the present embodiment will be described below with reference to FIGS.

First, the input means 101 acquires the cache data 103a stored in the storage unit 103 (step S201).

Next, the hierarchy information generation means 102a of the analysis means 102 analyzes the link relation of all the hypertext data contained in the cache data 103a obtained by the input means 101, and generates a hierarchy information list 103b (step). S202).

Next, based on the hierarchical information list 103b generated by the hierarchical information generating means 102a, the navigation information generating means 102b of the analyzing means 102 generates a navigation information list 103c according to conditions such as breadth priority and depth priority. Is generated (step S203). More specifically, the navigation information generating means 102b performs a process as shown in FIG. 9 in step S203. First, the navigation information generating means 102b generates the hierarchical information list 103 generated in step S202.
The link relationship of each data is checked with reference to b (step S2031). Next, the navigation information generating means 102b determines the order in which the hypertext data is displayed as pages according to search conditions such as depth priority, and assigns a number to information such as a link address corresponding to each hypertext data. (Step S203
2). Finally, the navigation information generating means 102b
Rearranges the link addresses respectively corresponding to the plurality of hypertext data in accordance with the numbers allocated in step S2032 (step S2033), and continues the subsequent processing.

When the navigation information list 103c is generated in step S203, the automatic navigation processing means 104
c, the link address corresponding to the page to be displayed first is obtained, and further according to the link address,
The hypertext data corresponding to the page to be displayed first is stored in the cache data 10 stored in the storage unit 103.
3a (step S204).

Next, the automatic navigation processing means 104
Controls to display the page to be displayed on the display means 105 for a certain period of time (step S205).

Thereafter, the automatic navigation processing means 10
No. 4 refers to the navigation information list 103c to determine whether or not there is a page to be displayed next (step S206), and further determines whether or not there has been an interruption process by the user (step S207).

Here, when it is determined in step S206 that there is no page to be displayed next, or in step S207
If there is an interruption process by the user, the browsing operation described above is terminated.

On the other hand, if it is determined in step S206 that there is a page to be displayed next, and if it is determined in step S207 that there is no interruption processing by the user, the automatic navigation processing means 104 executes the processing according to the navigation information list 103c. Then, the hypertext data corresponding to the page to be displayed next is obtained (step S20).
8) Then, the processing after step S205 is continued.

As described above, according to the hypertext data browsing apparatus of the present embodiment, each page is automatically browsed without performing the selection processing for selecting the hypertext data that the user wants to browse one by one. be able to.

(Second Embodiment) A hypertext data browsing apparatus according to a second embodiment of the present invention has a configuration as shown in FIG. As will be understood with reference to FIGS. 10 and 1, in the present embodiment,
Components that perform the same operations and processes as those in the first embodiment are denoted by the same reference numerals.

This embodiment shows an example in which the cache data 103a previously stored in the storage unit 103 in the first embodiment is obtained via the communication line 101a.

That is, in the first embodiment, the cache data 103a pre-stored in the storage unit 103 is targeted, and the hierarchy information generation means 102a and the navigation information generation means 102b perform
This is a mode in which processing is performed collectively on 3a. On the other hand, in the second embodiment,
(Hypertext data) existing on the network 101a such as (Local Area Network).
Accordingly, in the second embodiment, the hierarchical information generation unit 102a and the navigation information generation unit 1
In step 02b, the hierarchical information list 103b and the navigation information list 103c are sequentially updated while downloading a plurality of hypertext data.

The operation and processing in the hypertext data browsing apparatus according to the present embodiment will be described below with reference to FIG.

First, the input unit 101 obtains the first hypertext data by downloading it from the network via the communication line 101a, and temporarily stores the obtained hypertext data in the storage unit 103. (Step S301).

Next, the hierarchical information generating means 102a analyzes the hypertext data obtained by the input means 101, and sequentially generates a hierarchical information list 103b (step S302).

Next, the navigation information generating means 102
b generates the navigation information list 103c based on the hierarchical information list 103b sequentially generated and according to conditions such as breadth priority and depth priority (step S3).
03). At this time, if there is a page (hypertext data) to be displayed next, the link address of the hypertext data is set.

Steps S302 and S30
The process 3 will be described later in detail.

When the navigation information list 103c is generated in step S303, the automatic navigation processing means 104
c, storing the hypertext data corresponding to the page to be displayed according to the link address included in the storage unit 10
3 is obtained from the cache data 103a stored in Step 3 (Step S304).

Next, automatic navigation processing means 104
Controls to display the page to be displayed on the display means 105 for a certain period of time (step S305).

Next, automatic navigation processing means 104
Determines whether or not the interruption process has been performed by the user (step S306). If the interruption process has been performed by the user, the browsing operation described above ends.

If an end condition such as a hierarchical level is set for the hypertext data to be displayed, it is determined whether or not the browsing operation is to be ended according to the end condition (step S307). Here, as the end condition, for example, it is assumed that the display is performed from the root hierarchy to the hierarchy three levels lower in the depth direction, and when all the hypertext data to be displayed is displayed, the browsing operation is performed. Such as quitting. If the end condition has not been set, it goes without saying that step S307 is skipped and the process proceeds to the next process.

Next, in step S303, it is determined whether or not there is a link address of the hypertext data to be displayed next, and if not, the browsing operation ends (step S308).

If it is determined in steps S306 to S308 that the browsing operation is to be continued, the process returns to step S301, and according to the navigation information list generated in step S303, the link to which the hypertext data to be displayed next is set. Judging from the address, downloading from the network, the hierarchy information list 103b and the navigation information list 103c
Is generated again (updated).

As a whole, unless it is determined that the browsing operation is to be ended, a plurality of hypertext data are automatically and sequentially displayed in accordance with the navigation information list generated in step S303.

The following describes step S302 and step S302.
The operation at 303 will be described in more detail with reference to FIGS.

In step S302, image-like
Schematically, the hierarchical information generating means 102a generates the hierarchical information list 103b while sequentially downloading the hypertext data as shown in FIGS. Here, FIG. 12 shows a case where the search condition is breadth-first, and FIG. 13 shows a case where the search condition is depth-first. In FIG. 12, reference numerals 601 to 603 denote first, second, and third, respectively.
The state of the hierarchy information list 103b sequentially updated at the time of the second download is shown. In the drawing, the numbers in parentheses ([0] to [8]) indicate the display order of the hypertext data set in the next step S303. In FIG. 13, the components denoted by reference numerals 604 to 606 each have the same meaning as described above.

In step S303, image-like
Schematically, the navigation information generating means 102b
As shown in FIG. 14 and FIG.
In step 02, a navigation information list 103c is generated based on the hierarchical information list 103b that is sequentially updated by generation and combination. Here, FIG. 14 shows the navigation information list 103 in the case where the search priority is given to the area priority.
FIG. 15 shows a state of the navigation information list 103c when depth-first is set as a search condition. In FIG. 14 or FIG. 15, the numbers in parentheses ([0] to [8]) indicate the order in which the data are displayed, respectively, and these numbers are the same as those in FIG. 12 or FIG. Correspond to the numbers described in.

First, the case where the search priority is given to the area priority will be described.

When the hypertext data corresponding to the first page 401 shown in FIG. 4 is obtained from the network by the first download, in step S302, the first layer shown in FIG. Is generated.

In step S303, based on the first hierarchical information list 601, parentheses [0] to
As shown in [3], the display order of the hypertext data is ranked. The rearranged and stored link addresses of the ranked hypertext data in this manner are shown in FIG.
[3].

Further, in step S305, the first page to be displayed first ([0] in FIG. 12)
After the page designated by (1) (401 in FIG. 4) is displayed for a certain period of time, the process proceeds to step S308 via steps S306 and S307.

Here, the page to be displayed next is the second page (the page designated by [1] in FIG. 12; FIG. 4).
However, since the hypertext data corresponding to the second page is not stored in the storage unit 103, the process returns to step S301, and the hypertext data is downloaded from the network (second download). .

When the second download is performed,
Again in step S302, the hierarchical information generating unit 102a uses the acquired hypertext data to
The hierarchical data 602a shown in FIG. 12 is generated, and further combined with the previously generated first hierarchical information list 601 to generate the second hierarchical information list 602.

In step S303, the navigation information generating means 102b outputs the hierarchical data 6
02a is ranked as shown in [4] to [6] in FIG. 12, and [4] to [6] in FIG.
Is added to the navigation information list 103c.

Similarly, when hypertext data (hypertext data corresponding to [2] in FIG. 12; 403 in FIG. 4) is downloaded for the third time, in step S302, the hierarchical information generating means 102b outputs The hierarchical data 603a is generated, and further, the hierarchical data 603a and the second hierarchical information list 602
And a third hierarchical information list 603 is generated. Also in step S303, the navigation information generating means 102b performs ranking in the same manner as in the above-described processing procedure, and [7] to [7] in FIG.
As in [8], it is added to the navigation information list 103c.

Next, the case where depth priority is set as the search condition will be described.

When depth priority is used as the search condition, the display order in the depth direction in the hierarchy is determined preferentially, but link addresses within the same level (604a, 604a in FIG. 13).
The display order of 04b) is not determined until the lower-layer hypertext data is downloaded.

For example, a first hierarchical information list (604 in FIG. 13) is generated by the hierarchical information generating means 102a in step S302 from the hypertext data obtained in the first download.

Next, in step S303, the display order is ranked by the navigation information generating means 102b. Since the priority is given to the depth, the link address to be ranked at this time is the first address. 1
[0] and [1] in the hierarchical information list 604 of
These link addresses [1] and [2] are stored in the navigation information list 103c as shown by [0] to [1] in FIG.

When the second download is performed, in step S302, the hierarchy information generating means 10
2a, hierarchical data 605a is generated, and the hierarchical data 605a and the first hierarchical information list 604 are combined to generate a second hierarchical information list 605.

Further, in the ranking in step S303, only the link address indicated by [2] in the second hierarchical information list 605 is targeted, and the link address [2] is indicated by [2] in FIG. Thus, it is added to the navigation information list 103c.

Subsequently, when the third download is performed, in step S302, the hierarchical information generating means 10
2a, the hierarchical data 606a is generated and combined with the second hierarchical information list 605 to generate the third hierarchical information list 606.

Further, in step S303, the navigation information generating means 102b ranks the link addresses indicated by [3] and [4] in the third hierarchical information list 606, and ranks the links in FIG. 3] to [4], the navigation information list 1
03c. Here, since the lower-level data is not linked to the hypertext data indicated by the link address [3] in the third hierarchical information list 606, the link address [ 4] is determined to be displayed next.

Thereafter, as long as the browsing operation is not completed, the above-described processing loop is repeated.

In the above-described first and second embodiments, there is no limitation on the tags for which the hierarchical information list is generated. For example, the following conditions may be added. Good.

Generally, a link address that links to another page or a non-displayed portion of the current page is:
<A HREF = “”... Is described in the hypertext data. Here, the content between the double quotes indicates the actual link address.
Divided into types. One is a link address specified by an absolute path, the other is a link address specified by a relative path, and the last one indicates a link to the same page. . Where "absolute path"
Specifies the location of a file from the top-level directory, and contains a complete URL (Uniform Resource
ce Locator).
The “relative path” designates the position of a file based on the currently displayed page (hypertext data). In addition, a link to the same page has a data name added to the link destination in advance, and the data name is prefixed with # to be a link address.

Therefore, conditions may be set appropriately in consideration of the characteristics of each link address described above, for example, excluding the link address starting with # from the object of the generation of the hierarchical information list.

In the first and second embodiments, the following functions may be added.

For example, when an automatic scroll means 105a is added to the display means 105 in FIGS. 1 and 10,
When displaying hypertext data as a page,
If the page is larger than the display area, scroll processing is automatically performed on the page at a predetermined speed. As a result, data that was initially outside the display area is automatically displayed.

FIG. 16 is a diagram showing a specific example in the case where scroll processing is performed by the display means 105 having such an automatic scroll means 105a. As can be understood with reference to FIG. 16, the screen 901 displays a page that does not fit in the display area.
Automatically scrolls the page displayed in
By scrolling a, a screen 902 is obtained. Also, as shown in the screen 902, when scrolling to the end of the page, that is, to the end of the body of the hypertext data, next, according to the navigation information list,
Furthermore, it automatically moves to the link destination indicated by 901a,
The process of obtaining the screen 903 and performing scroll processing on the page displayed on the screen 903 is repeated.

In the above description, a browsing device for browsing hypertext data has been described. However, a program for causing a computer to execute the same processing is stored in a storage medium, and the storage medium is incorporated in the computer. Thus, the program may be executed to achieve a similar result.

[0090]

As described above, according to the present invention, a browsing apparatus capable of automatically and sequentially displaying a plurality of hypertext data as pages can be obtained. It is very easy to search for the desired hypertext data. Also, at this time, since the user can operate without being conscious of the concept such as the hypertext structure and the hierarchical structure, the beginner can easily receive the WWW service.

Furthermore, since the present invention simplifies the operation for browsing hypertext data as a page, a remote controller such as a video or audio device may be used instead of a special input device (eg, a mouse or keyboard in a computer) It can be operated by a general input device such as.
