DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an Internet browsing apparatus for accessing a database or the like on a network and displaying information.

[0002]

2. Description of the Related Art In recent years, WWW (World Wide Web) services for accessing various information on the Internet have begun and are rapidly spreading. In particular, Internet browsing devices that graphically display WWW information have been appearing one after another.

Conventionally, a gateway device for the Internet is disclosed in Japanese Patent Laid-Open No. 8-44643, and a graphical user interface for a network device is disclosed in Japanese Patent Laid-Open No. 6-243066. Although these do not show an Internet browsing device, they do show some technical background used in Internet browsing devices.

[0004] First, the terms used here will be explained. The client is a terminal device from which a user actually accesses the Internet, and the server is a gateway for connecting the client to the Internet. For example, a user connects to a server (gateway) of an Internet provider from a client, and accesses the Internet via this server. A WWW server provides information such as a homepage on the Internet.

[0005] An example of a conventional Internet browsing apparatus will be described below with reference to the drawings. FIG. 8 shows an example of a conventional Internet browsing apparatus.

In FIG. 8, reference numeral 1 denotes data transmitting / receiving means;
Is reception data identification means, 3 is reception data analysis means, 6 is display setting means, 9 is display output means, 10 is a display device,
1 is an image data developing means, 70 is a pointing device,
Reference numeral 13 denotes an input analysis unit, 14 denotes a link destination specifying unit, and 15 denotes a data request destination setting unit.

Here, the data transmission / reception means 1 is connected to a server or the like by a protocol such as TCP / IP through a communication interface such as a modem, and is connected to the Internet via the server. The file acquired by the data transmitting / receiving means 1 from the Internet is input to the received data identification means 2. The received data identification means 2 classifies the type of the received file, and the hypertext file is input to the received data analysis means 3. The received data analysis means 3 analyzes the syntax (tag) in the hypertext file and determines the arrangement of the character strings and image data in the document. In addition, the received data analysis means 3 uses another file (for example,
Data request destination setting means 1
Then, a request for transfer of this file is issued to 5. The data request destination setting means 15 receives the transfer request, generates an absolute address of the file, and the data transmission / reception means 1 goes to the server and retrieves the file. Similarly, the files received by the data transmission / reception means 1 are classified by the received data identification means 2 for each type. When the received file is an image file, this file is sent to the image data expanding means 11, and in the case of a data compressed file (for example, a JPEG compressed image file), expansion corresponding to the compression format is performed, Generate image data in the format.

The display setting means 6 sets the size and color of the character string, the character decoration for identifying the presence or absence of link information, and the like in accordance with the arrangement of the character string and the image data determined by the reception data analyzing means 3. Is developed in a bitmap format, and the arrangement position on the virtual screen is determined and mapped together with the image data and the like generated by the image data developing unit 11. Further, a display screen is set within a range that can be displayed on the display device 10 within the virtual screen, and a scroll bar is added to the display screen when the virtual screen is larger than the display screen.

The display output means 9 performs D / A conversion of the data on the display screen and outputs the data as an analog signal. Further, the display device 10 is constituted by a CRT display or the like, and displays an output signal of the display output means 9 on a screen.

The output of the pointing device 70 is input to the input analysis means 13 and analyzed. Here, the pointing device 70 is constituted by a mouse or the like, and the movement information of the mouse cursor accompanying the movement of the mouse is analyzed by the input analyzing means 13, and the display position of the next mouse cursor is determined. The data is combined with the data of the display screen by the means 9 and displayed on the display device 10. In addition, when the user looks at the display screen and wants further link destination information, he / she clicks an anchor indicating desired link destination information displayed on the display device 10 using the pointing device 70. The information that the mouse has been clicked is analyzed by the input analysis unit 13, and the position of the mouse cursor where this event has occurred is output to the link destination specifying unit 14. The link destination specifying unit 14 specifies the link destination information based on the data on the display screen generated by the display setting unit 6 and the position information of the mouse cursor, and issues a transfer request of this file to the data request destination setting unit 15. Then, the data request destination setting means 15 receives this transfer request,
The absolute address of this file is generated, and the data transmitting / receiving means 1 retrieves the file via the server.

Here, the server operates as a gateway, and fetches a file requested by the client onto the Internet using an appropriate protocol. When the server obtains the file requested by the client from the Internet, the server transmits the file to the client, stores the file data on the server for a certain period of time, and caches the file data.

In this way, the user browses while sequentially searching for hypertext (homepage) on the Internet.

[0013]

However, in the above-described configuration, the environment such as the screen size of the creator of the hypertext does not always match the environment of the viewer. When browsing with a small number of Internet browsing devices, the character string or title of the anchor indicating the link destination information is broken on the way, making it very difficult to see. Further, when the size of the image data in the horizontal direction of the screen is larger than one screen of the display screen, it is necessary to scroll in the horizontal direction, so that not only is it difficult to see, but also the operability deteriorates.

Further, if these problems are to be dealt with only by the client, the load on the client becomes heavy.
There was a problem that operability was deteriorated such as deterioration of response.

[0015] The syntax of the hypertext is expanded every day, and if only the client is sold as a product, it is necessary to upgrade the analysis processing or the like for each client, which is very difficult. There was a problem that much labor was required.
Also, if you do not upgrade the version, not only the part described with the new syntax can not be displayed,
There was a problem that the display was incorrect and the operability and visibility deteriorated.

In addition, since the operation is performed using a pointing device such as a mouse, it is difficult for a beginner to use, and in particular, there is a problem that it takes time to specify an anchor indicating link destination information.

An object of the present invention is to provide an Internet browsing apparatus which has a user interface with good visibility and operability, and which can easily cope with a new syntax. Aim.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An Internet browsing apparatus according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an Internet browsing apparatus according to a first embodiment of the present invention. FIGS. 2A and 2B show display examples of the Internet browsing apparatus according to the present embodiment. It is shown.
Here, the same components as those of the conventional example are denoted by the same reference numerals, and description thereof will be omitted. In this embodiment, the server has the same configuration as that of the conventional example.

As shown in FIG. 1, the Internet browsing apparatus includes data transmitting / receiving means 1, received data identifying means 2, received data analyzing means 3, display setting means 6,
Display output means 9, display device 10, image data expanding means 1
1, input device 12, input analyzing means 13, link destination specifying means 14, data request destination setting means 15, display position correcting means 4, screen size setting means 5, moving position setting means 7, designated position displaying means 8, Is provided.

Here, the file obtained by the data transmission / reception means 1 from the WWW server on the Internet is input to the reception data identification means 2, and the type of the file is classified. Hypertext file is received data analysis means 3
The image file is input to the image data expanding means 11. Here, other files, for example, a simple text file, may be directly output to the display setting means 6, or an appropriate process may be performed for each file requiring some processing.

The received data analyzing means 3 analyzes the syntax (tag) in the hypertext file,
The arrangement (display order) of character strings and image data in the document is determined. When there is another file (for example, image data to be displayed in a document) necessary for displaying this document, the received data analysis unit 3 sends a transfer request of this file to the data request destination setting unit 15. put out.

The display position correcting means 4 obtains information on the display screen size from the screen size setting means 5 and generates a virtual screen having a horizontal width equal to or smaller than the horizontal width of the display screen. here,
The display screen size is a screen size for actually displaying a hypertext, and is different from a screen size of a CRT or the like. Then, information on the arrangement of each character string and image data and information on the size of each character string are obtained from the received data analysis means 3, and information on the size of the image data is obtained from the image data expanding means 11. The character string and the display start position of the image data are determined. Here, a line feed is performed for a character string that extends beyond the horizontal width of the virtual screen, and is accommodated in the virtual screen. However, in the case of a character string having link destination information (anchor character string), a line feed is not performed in this character string. However, as shown in FIG. 2A, when this character string has a horizontal size larger than the horizontal width of the display screen, this character string is equally divided into a plurality of lines, and each line from the same position in the horizontal direction of the screen. Place.

When a character string is displayed beside image data, the character string is equally divided into a plurality of lines, and each line is displayed from the same position in the horizontal direction of the screen. Further, when character strings are displayed on the left and right of the image data as shown in FIG. 2B, the ratio of the length of the character string displayed on the right side of the image data to the length of the character string displayed on the left side of the image data is determined. Then, the length obtained by subtracting the width of the image data from the width of the display screen is divided by this ratio to determine the length of each character string to be displayed in the horizontal direction (display length).
Then, each character string is divided into a plurality of lines of display length and arranged.

The display setting means 6 obtains information on the arrangement position of each character string and image data from the output of the display position correcting means 4 and maps the character string and image data on the virtual screen. Output the page number as a display screen. Here, the width of the virtual screen is the same as the display screen, but the vertical width differs depending on the received hypertext file. Is the first page. Similarly, the second page is the second page from the end of the first page to the position of the same vertical width as the display screen.
In the same manner, pages 3, 4,... of course,
The width of one page in the vertical direction may be shorter than the display screen, and an area may be provided in which adjacent pages are overlapped and displayed.

Immediately after receiving the hypertext data, the moving position setting means 7 positions the cursor at the center position of the anchor having the first link information of the first page. Here, the anchor is a character string or an image having link information. At this time, if there is no anchor on the first page, the user is notified that there is no anchor on this page by changing the beep sound, cursor shape, color, and the like. Although the cursor is used here, the anchor character string may be displayed in reverse video or displayed as a push button by changing its color or shape to use it instead of the cursor.

Next, the pointing position display means 8 combines the cursor output from the moving position setting means 7 on the display screen, converts the cursor into an analog signal by the display output means 9, and displays the analog signal on the display device 10.

While looking at the display screen of the display device 10, the user searches for information to be searched next (for example, a homepage) and designates it using the input device 12. FIG. 3 shows the input device 1
2 shows an example of the infrared remote controller for a television that can also watch the Internet. The remote control includes a television channel button 12a and the like, a direction key 12b composed of four arrow keys formed in a cross shape for moving a cursor up, down, left and right, and a selection key 12c for designating information to be searched next. A back key 12d for returning to the immediately preceding information, a forward key 12e for returning to the immediately preceding information, a reload key 12f for redisplaying, a stop key 12g for stopping reading of a file during communication, and a screen. Scroll key 12h for scrolling, input key 12i for directly shifting to a mode for entering a homepage (hypertext) address, and shifting to a mode for selecting and displaying a frequently viewed homepage (hypertext) and storing an address. Bookmark key 12
j and the like. Of course, the direction key 12b only needs to be able to specify at least four directions, up, down, left, and right.

FIG. 4 is a flowchart of the operation of the input device 12 at the time of key input. If there is a key input in step 101, the input signal by the direction key of the input device 12 is determined by the input analysis means 13 (steps 103 to 1).
06), it is determined whether or not there is an anchor in the direction corresponding to the pressed key (steps 107 to 110). If there is an anchor in the direction corresponding to the key pressed,
The cursor is moved to the position of the next anchor in the direction corresponding to the key pressed by the movement position setting means 7 (steps 113 to 116). At this time, when there is no anchor in the direction corresponding to the pressed key, for example, when there is no rightward anchor in response to a rightward instruction, the anchor is moved to the downward anchor (steps 103, 107, 109, and 11).
4) If there is no leftward anchor in response to the leftward instruction, move to the upward anchor (step 104,
108, 110, 113).

If the first anchor on the first page is to be directed leftward or upward, step 10
Steps 108, 110, 111, 11 from 4,106
8 and proceed to step 122, without changing the position of the cursor, the user is alerted by a change in the shape or color of the cursor, a beep sound, etc. When the instruction is to the left, the previous page is displayed by scrolling the page (step 111) and the user is alerted (step 1).
22). Here, when alerting the user, the shape and color of the cursor and the volume and tone of the beep sound may be changed according to various situations.

Similarly, when pointing to the right or downward with respect to the last anchor of the last page, without changing the position of the cursor, the user is alerted by a change in the mouse shape or a beep sound. Then, for the last anchor other than the last page, the next page is displayed by page scrolling (steps 103, 105, 107, and 10).
9, 112, 119, 122).

Further, when the direction key is pressed while the scroll key 12h is pressed, step 102 is executed.
Then, the process proceeds to steps 111 and 112 via steps 123, 124, 125 and 126, and the display screen is scrolled by a page. At this time, the right direction instruction of the direction key may correspond to the downward scroll, and the left direction instruction may correspond to the upward scroll. Of course, scroll key 12h
May be a toggle operation, and may be set to a scroll mode when pressed once and to a cursor movement mode when pressed again.

Further, the moving position setting means 7 instructs the pointing position display means 8 to indicate the position of the cursor and the position of the display screen on the virtual screen, and updates the display screen. The input signal from the selection key 12c of the input device 12 is determined by the input analysis unit 13, the link destination specifying unit 14 specifies the link destination information indicated by the anchor, and the data request destination setting unit 15 converts the link destination address to an absolute address. After conversion, a desired file is acquired by the data transmission / reception unit 1.

The server operates as a gateway, and acquires a file requested by the data transmitting / receiving means 1 from the Internet using an appropriate protocol. In addition,
In this embodiment, although caching of data and the like are not mentioned, it is also possible to cache a read homepage by a client, thereby eliminating unnecessary communication and shortening the data communication time.

As described above, according to the present embodiment, the received data analyzing means 1 for analyzing received character data, and the image data expanding means 11 for expanding received image data to generate image data and obtain an image size. Image size setting means 5 for setting a display screen size; display position correction for calculating display positions of characters and images from received character data and the image size and correcting the display position in accordance with the horizontal size of the display screen Means 4 and display setting means 6 for mapping the characters and the image on the display screen from the output of the display position correcting means 4 so that the character string can be appropriately line-returned and displayed close to the intention of the information creator. And visibility and operability can be improved.

Moving position setting means 7 for obtaining anchor information indicating the position of a character string or image having link information from the display setting means 6 and moving the cursor to the position of the anchor information by an input operation; By providing the indication position display means 8 for synthesizing the output of the movement position setting means 7 on the display screen output by the display setting means 6, it is possible to search and browse the link information by a simple operation.

When there is no character string having a link information or an anchor indicating an image in the direction specified by the input operation on the display screen, the page is scrolled in the direction specified by the input operation and the new display screen is displayed. By moving the cursor to the anchor closest to the previous display screen, the screen and the cursor can be moved only with the directional key 12b, and the operability can be improved.

Further, if there is no anchor indicating a character string or image having link information on the next page in the direction specified by the input operation, the page is scrolled in the direction specified by the input operation, and the anchor is displayed on the display screen. By notifying the user that there is no page, even a page without an anchor can be easily displayed, and all pages can be viewed with a simple operation, and the user can intuitively understand the display state.

Movement of the screen and the cursor is performed by using directional keys 12b indicating at least four directions of up, down, left, and right, and a scroll key 12h provided on the input device 12 is used to distinguish between screen movement and cursor movement. Accordingly, even when an image or information is displayed halfway by a page break, the display on the screen can be easily viewed by a simple operation. Further, by also using the direction key 12b for moving the screen and the cursor, the screen and the cursor can be moved with a small number of keys, so that the input device can be downsized and the operation can be simplified.

Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 5 is a block diagram of an Internet browsing apparatus according to a second embodiment of the present invention.

As shown in FIG. 5, in the Internet browsing apparatus, an image size changing means 20 and a character size changing means 21 are provided in addition to the components of the first embodiment. Here, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. In this embodiment, the server has the same configuration as that of the conventional example.

The file obtained by the data transmitting / receiving means 1 from the WWW server on the Internet is input to the received data identification means 2 and classified according to the type of the file. The hypertext file is input to the received data analysis means 3.
The image file is input to the image data expanding unit 11.
The received data analysis means 3 analyzes the syntax (tag) in the hypertext file and determines the arrangement (display order) of the character strings and image data in the document.

Next, the display position correcting means 4 obtains the information of the display screen size from the screen size setting means 5 and generates a virtual screen having a width equal to or smaller than the horizontal width of the display screen. Then, information on the arrangement of each character string and image data and information on the size of each character string are obtained from the received data analysis means 3, and information on the size of the image data is obtained from the image data expanding means 11. Here, when the horizontal size of the image is equal to or larger than the horizontal width of the display screen, the reduction ratio is output to the image size changing unit 20. This reduction ratio is obtained by dividing the horizontal width of the display screen by the horizontal size of the image data.

The width in the horizontal direction of a character string modified as a title character by a tag, a character string modified as a heading character, and a character larger than a normally displayed character is designated is displayed. If the width is equal to or larger than the horizontal width of the screen, the reduction ratio is output to the character size changing means 21 so as to change the size of the character of this character string,
Instruct reduction. This reduction ratio is obtained by dividing the horizontal width of the display screen by the horizontal size of the character string.

The image size changing means 20 reduces the bitmap format image data output from the image data expanding means 11 at the reduction ratio specified by the display position correcting means 4, and outputs the bitmap format image data to the display setting means 6. Output. Of course, image data that should not be reduced is output to the display setting means 6 as it is.

The character size changing means 21 obtains information on the character string to be displayed according to the syntax, the character string to be reduced and the reduction ratio from the display position correcting means 4, and changes the character point number of the character string to be reduced. Thus, the image is reduced and output to the display setting means 6. Here, the size of the reduced character string is at least larger than or equal to a normally displayed character (standard character). At this time, even if it is the same size as the characters normally displayed, if it becomes larger than the width of the display screen in the horizontal direction, this character string is divided into equal parts, and the original character string size is used as a multi-line character string. indicate. Further, if the character string is reduced in size to become a character having the same size or a similar size as a character string normally displayed, a character decoration such as bolding or addition of an underline may be added to the character string.

The display setting means 6 obtains information on the arrangement position of each character string and image data from the output of the display position correcting means 4 and further converts the image data output by the image size changing means 20 into the character size changing means. The character string data output by 21 is mapped on a virtual screen, and the first page on the virtual screen is output as a display screen.

As described above, by providing the image size changing means 20 and the character size changing means 21 and displaying within the horizontal width of the display screen, horizontal scrolling can be eliminated and a screen display which is easy to use and easy to see can be realized. .

In the present embodiment, the received image is reduced by the image size changing means 20. However, when the aspect ratio of the display screen of the Internet browsing device is different from the aspect ratio of the screen of the homepage creator, the image size is reduced. It is also possible to convert the aspect ratio of the image by the conversion means 20. For example, even when the aspect ratio of the screen of the homepage creator is 4: 3 and the aspect ratio of the display screen is 16: 9, the image size can be changed. By correcting the aspect ratio of the image by the means 20, the image can be displayed accurately without being delayed in the horizontal direction. The same applies to the character size changing means 21. Characters may be changed to a vertically long character font.

When the display screen is small, the image may be enlarged and displayed by the image size conversion means 20, so that the display screen can be easily viewed. Hereinafter, a third embodiment of the present invention will be described with reference to the drawings.

FIG. 6 is a block diagram of an Internet browsing apparatus according to a third embodiment of the present invention. As shown in FIG. 6, the Internet browsing apparatus includes a first server transmitting / receiving unit 51, an image size obtaining unit 52, a transmission data generating unit 53, a second server transmitting / receiving unit 54, and a data requesting unit 55. , An image decoding unit 56, a character size correcting unit 57, a server control unit 58, and an image encoding unit 59. Here, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

First, the server will be described. The file acquired by the first server transmission / reception unit 51 from the WWW server on the Internet is input to the reception data identification unit 2, and the type of the file is classified. The hypertext file is input to the received data analysis means 3, and the image file is input to the image size acquisition means 52. Here, other files, such as a simple text file, are
May be directly output to the server transmission / reception means 54, or a file requiring some processing may be subjected to appropriate processing and transmitted to the second server transmission / reception means 54. The received data analysis means 3 analyzes the syntax (tag) in the hypertext file and determines the arrangement (display order) of the character strings and image data in the document. Also,
When there is another file (for example, image data to be displayed in a document) required for displaying this document, the reception data analysis unit 3 issues a transfer request of this file to the data requesting unit 55. The data requesting means 55 generates an absolute address of this file, and the first server transmitting / receiving means 51 acquires the file of this address.

The image size obtaining means 52 obtains an image file from the received data identification means 2 and extracts information on the size of the image data. The display position correcting means 4 obtains information on the display screen size used by the client from the screen size setting means 5 and generates a virtual screen having a horizontal width equal to or smaller than the horizontal width of the display screen. Then, information on the arrangement of each character string and image data and information on the size of each character string are obtained from the reception data analysis means 3, and information on the size of the image data is obtained from the image size acquisition means 52. The display start position of the character string and the image data is determined. here,
In the case of a character string having link destination information, a line feed is not performed in this character string. However, when the character string has a horizontal size equal to or larger than the horizontal width of the display screen, the character string is equally divided into a plurality of lines, and each line is arranged from the same position in the horizontal direction. If you want to display a character string next to the image data,
The character string is equally divided into a plurality of lines, and each line is displayed from the same position in the horizontal direction of the screen. Furthermore, when displaying character strings on the left and right of the image data, the ratio of the length of the character string displayed on the right side of the image data to the length of the character string displayed on the left side of the image data is calculated from the width of the display screen. The length obtained by subtracting the horizontal width of the data is divided by this ratio to determine the length of each character string to be displayed in the horizontal direction (display length). Then, each character string is divided into a plurality of lines of display length and arranged.

When the horizontal size of the image is equal to or larger than the horizontal width of the display screen, the reduction ratio is output to the image size changing means 20. This reduction ratio is obtained by dividing the horizontal width of the display screen by the horizontal size of the image data.

The width in the horizontal direction of a character string modified as a title character by a tag, a character string modified as a heading character, and a character larger than a normally displayed character is designated is displayed. If the width is equal to or larger than the horizontal width of the screen, the reduction ratio is output to the character size changing unit 21 so as to change the size of the character of the character string.

The image decoding means 56 obtains an image file from the image size obtaining means 52, decodes the image file to be compressed specified by the display position correcting means 4, and obtains bitmap image data. Image size changing means 2
A value of 0 reduces this image data at the reduction ratio instructed by the display position correcting means 4 and outputs it to the image encoding means 59 as a bitmap image file. The image encoding means 59 compresses this image file into the same format as the original image. Here, the file name of the reduced image data is changed according to the instruction of the transmission data generation unit 53. Of course, for image data that should not be reduced, the received image file is output to the second server transmitting / receiving means 54 as it is.

The character size correcting means 57 obtains information on the character string to be displayed according to the syntax, the character string to be reduced and the reduction ratio from the display position correcting means 4, and changes the character point number of the character string to be reduced. By doing so, the tag is changed so as to reduce the size and output to the second server transmitting / receiving means 54. Here, the size of the reduced character string is at least larger than or equal to a normally displayed character string. At this time, even if the characters are the same size as the characters normally displayed, if the characters become larger than the width of the display screen in the horizontal direction, the character strings are equally divided, and the size of the original character strings is the same in the horizontal direction of the screen. Display as a multi-line character string starting from the position of. further,
If the reduced size results in a character having the same or a similar size as a normally displayed character string, a character decoration tag such as bolding or adding an underline may be added to the character string.

The transmission data generating means 53 obtains the corrected hypertext from the output of the character size correcting means 57, and when the image data is reduced, changes the file name of the image data to a new name. The image data file name in the hypertext is corrected, and the new name is also notified to the image encoding means 59. Then, use this modified hypertext as a file,
It is sent to the second server transmitting / receiving means 54.

On the other hand, the transmission request from the client is
The first server transmitting / receiving unit 51 acquires a file on the Internet through the data requesting unit 55.

In the server, processing such as data caching is also performed by the server control means 58, and when the transmission request file accepted by the second server transmission / reception means 54 is in the server, the first server transmission / reception means 51 The second server transmitting / receiving means 54 transmits the file in the server to the client without operating the server.

Next, the operation of the client will be described. Data obtained by the data transmitting / receiving means 1 from the Internet is input to the received data identification means 2. The received data identification means 2 classifies the type of the received file, and the hypertext file is input to the received data analysis means 3 to analyze the syntax (tag) and determine the arrangement of character strings and image data in the document. When there is another file (for example, an image file) required for displaying this document, the reception data analysis unit 3 issues a transfer request of this file to the data request destination setting unit 15. The data request destination setting means 15 receives the transfer request, generates an absolute address of the file, and the data transmission / reception means 1 goes to the server and retrieves the file. When the received file is an image file, the file is sent to the image data expanding unit 11, and the data compressed file is expanded according to the compression format to generate bitmap image data.

The display setting means 6 determines the size and color of the character string according to the tag according to the arrangement of the character string and the image data determined by the received data analysis means 3, and further includes a character decoration for identifying the presence or absence of link information. Is performed to develop these characters into a bitmap format, determine the arrangement position on the virtual screen together with the image data generated by the image data developing unit 11, and perform mapping.

The method of displaying the cursor and the operation at the time of key input from the input device 12 are the same as in the first embodiment. In the present embodiment, the size of the character string and the image is changed by the server, but only one of the sizes may be changed by the server.

As described above, the server is provided with the image size changing means 20 and the character size correcting means 57, and the client modifies the hypertext so that the image and the character string are displayed within the width of the display screen. This eliminates the need to perform the above processing, thereby simplifying the configuration of the client. In addition, when one server has many clients, it is not necessary to perform these processes by several clients, and the processing efficiency is high. Further, by performing these processes on a server having high processing capability, the size of a character string or an image can be changed in a short time, and the response time from a user's requested operation to display can be improved.

The received data identification unit 2 classifies the type of the received file, and outputs the file other than the hypertext file to the second server transmission / reception unit 54 as it is. In the case of a hypertext file, it is output to the received data correcting means 63.

The received data correcting means 63 analyzes the syntax (tag) in this file, determines whether or not any tag other than the old tag in the new / old tag conversion table 62 exists in this file. Directly outputs this file to the second server transmitting / receiving means 54.

If a new tag other than the old tag is included, the received data correcting means 63 replaces the new tag with the old tag corresponding to the new tag using the new / old tag conversion table 62, 2 to the server transmitting / receiving means 54. Of course, here, the conversion from the new tag to the old tag is not limited to simply replacing the tag, but may also change the content such as a character string modified by the new tag. That is, the new / old tag conversion table 62 is not limited to the one-to-one conversion table from the new tag to the old tag, but includes a case where a single new tag includes a plurality of old tags, It also remembers how to change the character string that is present. For example, if there is no tag for performing centering in one line of the character string as an old tag of the character string, and if a hypertext file including a tag indicating centering is received, the reception data correcting unit 63 determines that the tag indicating centering is Recognizing that the tag is a new tag, the tag is converted to the old tag by the new / old tag conversion table 62. Here, the old tag for the tag indicating centering is changed so that a blank character is inserted into the character string to be centered, the new tag is corrected with the tag (old tag) indicating the formatted document, and the centering display is performed. You. Of course, the display screen size at this time is considered when creating the new / old tag conversion table 62.

It is to be noted that processing may be performed so that the new tag is converted to the old tag by the received data correcting means 63 without using the new and old tag conversion table 62. Further, the received data correcting means 63 converts a bug or the like of the client (a defect in the syntax processing or an inconvenience in the hypertext notation) into a syntax or the like which normally operates on the client.
By transmitting, it is possible to easily cope with a bug or the like of the client.

Note that the client is the same as in the fourth embodiment, and the received data analysis means 3 of the client recognizes and displays only the old tag. The method of displaying the cursor and the operation at the time of key input from the input device 12 are the same as in the first embodiment.

Further, as the client, the Internet browsing apparatus described in the first or second embodiment may be used. If the client can recognize only the old tag and display it correctly, the client can use the Internet browsing apparatus. Good.

As described above, the server is provided with the new / old tag conversion table 62 and the received data correction means 63, and the tags which cannot be interpreted by the client are converted into tags which can be interpreted by the server by the server, so that the hypertext syntax can be extended. Can be dealt with simply by changing the server software, eliminating the need to change a very large number of individual clients. In addition, it is possible to eliminate the possibility that the display of the hypertext becomes inaccurate due to the undefined tag in the client. Further, inconveniences such as client bugs can be dealt with by the server.
