[0053]
FIG. 12 is a diagram showing a specific example of the data 63a to 63n in FIG. 10, and shows a case where the content of the data is described in HTML (HyperText Markup Language). Note that the data is not necessarily HTML.
[0054]
Next, the received mail registration process 1300 of the terminal device 1 (FIGS. 2 and 3) performed when the electronic mail 6 is received will be described with reference to FIG.
[0055]
In the figure, first, a new record 907 is added to the mail management table 900 shown in FIG. The URL 901 of the added record 907 is the data URL 62 of the received mail control unit 62 (FIG. 10), the expiration date 902 is the expiration date 1102 (FIG. 11), and the attribute 903 is the display / non-display attribute 1101 (FIG. 10). 11) is stored (step 1301). If there is a plurality of data 63 (FIG. 10) in step 1301, step 1301 is repeated a plurality of times.
[0056]
Next, a new record 503 is added to the cache management table 500 shown in FIG. The URL 501 of the added record 503 stores the contents of the data URL 1105 (FIG. 11) of the received email 6. Then, the contents of the data 63 (FIG. 10) corresponding to the data URL 1105 are stored in the cache. At this time, for example, numbers are assigned sequentially from 1, and file names are assigned. Then, this file name is stored in the file name 502 (step 1302). If there is a plurality of data 63 (FIG. 10) in step 1302, step 1302 is repeated a plurality of times.
[0057]
Next, a new record 703 is added to the disk link management table 700 (FIG. 7) stored in the storage unit 1b (FIG. 3). The information ID 701 of the added record 703 stores the contents of the information ID 1106, and the disk information 702 stores the contents of the disk information 1107 (step 1303). If there are a plurality of pieces of disk link information 1103, the process of step 1303 is repeated a plurality of times.
[0058]
The cache means an area for storing a file secured in the storage unit 1b (FIG. 3). Further, for receiving the e-mail 6, for example, a protocol such as POP3 that is standardly used for receiving e-mail on the Internet is used.
[0059]
Next, a received mail list acquisition process 1400 for acquiring a list of mails registered in the received mail registration process 1300 will be described with reference to FIG.
[0060]
In the received mail list acquisition process 1400, first, the variable i is set to 0 (step 1401). If i is smaller than the number of records registered in the mail management table 900 (FIG. 9) (step 1402), the process proceeds to step 1403. Otherwise, the process ends.
[0061]
In step 1403, the attribute 903 of the i-th record 907i is examined. If this attribute 903 is an attribute to be displayed to the user, HTML data (data described using HTML) for displaying a mail list is displayed. , The sender 904 of the record 907i, the transmission date 905, and the title 906 are inserted. At this time, a link is established using the <A> tag for the sender, transmission date, and title. The link destination is the URL of record 907i (step 1404). After step 1404 ends, the process returns to step 1402. In step 1403, if the attribute 903 is an attribute that is not displayed to the user, the process returns to step 1402.
[0062]
An example of HTML data created by the above procedure is shown in FIG.
[0063]
Next, the processing in the terminal device 1 (FIG. 3) for displaying the data acquired by the package media 3, the network (telephone line 5) and the e-mail 6 mixed on the screen will be described. The screen display processing 1600 will be described with reference to FIG.
[0064]
In the figure, an HTML file (file described using HTML) of a URL specified by the user or a link destination URL specified by the user is acquired (step 1601). Next, it is checked whether or not data such as an image to be taken in is specified in the acquired HTML file (step 1602). Note that there are tags specified in HTML, such as <IMG>, <EMBED>, etc., as tags for specifying the capture of images and the like. If there is data to be captured, the data is read (step 1603). Repeat data acquisition until there is no more data to capture.
[0065]
When there is no data to be captured, the HTML file and the data captured based on the designation of the HTML file are displayed (step 1604).
[0066]
In addition, although the data acquisition process 1700 is used for taking in an HTML file and data, this data acquisition process 1700 will be described with reference to FIG.
[0067]
In the figure, first, it is searched whether there is a record having the same URL 501 in the cache management table 500 (FIG. 5) for the specified URL (step 1701). If this record exists, the file specified by the file name 502 of the retrieved record is read from the cache (step 1705).
[0068]
If there is no URL specified in the cache management table 500, the disk management table 600 (FIG. 6) is searched for a record included in the URL specified by the information ID 601 (step 1702). If this record exists in the disk management table 600, a portion that matches the information ID 601 of the record retrieved from the URL is removed, and a file in which the directory 602 and the removed portion are concatenated is accessed (step 1706).
[0069]
For example, a record in which the specified URL is “//www.sv/ID00001/test.html”, the information ID 601 is “//www.sv/ID00001”, and the directory 602 is “IDD0001” in the disk management table 600. Is present, “IDD0001 / test.html” present on the package medium 3 (FIG. 2) is accessed.
[0070]
If it does not exist in the disk management table 600, a process selection dialog is displayed that prompts the user to insert another package medium 3, read from the network, or cancel the process (step 1703).
[0071]
An example of the process selection dialog 1800 displayed at step 1703 is shown in FIGS. In the process selection dialog 1800, as shown in FIG. 18A, a message 1801 specifying the package medium to be inserted by the user, a button 1802a for notifying that the setting is completed, and notification of reception from the network are notified. There are a button 1802b and a button 1802c for notifying that processing is cancelled.
[0072]
Whether the message 1801 includes a record included in the URL specified by the information ID 701 in the disk link management table 700 (FIG. 7) existing in the storage unit 1b (FIG. 3) and the package medium 3 (FIG. 2). Search for no. If this record exists, the disc information 702 of this retrieved record is read and displayed as part of the message. If the record does not exist as a result of the search, a message 1803 notifying that there is no disk is displayed in the process selection dialog 1800 instead of the message 1801 as shown in FIG.
[0073]
By displaying the above dialog, it is possible to inform the user which package medium 3 should be inserted.
[0074]
When the button 1802a is selected in the process selection dialog 1800, the process returns to step 1702 in FIG. When the button 1802b is selected, communication processing 1707 for reading data from the network is performed. The communication processing 1707 will be described later with reference to FIG. If the user selects the button 1802c, an HTTP error response (an error response defined by HTTP (HyperText Transfer Protocol), which is one of the communication protocols used on the Internet) is created (step 1708).
[0075]
Next, the communication processing 1707 will be described with reference to FIG.
[0076]
In the figure, first, it is checked whether or not the telephone line 5 (FIG. 2) is connected (step 1901). If the telephone line 5 is connected, the process proceeds to step 1903. If the telephone line 5 is not connected, the telephone number 801 is read from the server management table 800 (FIG. 8) and dialed. After the telephone line 5 is connected, the server 4 (FIG. 2) is logged in using the user ID 802 and password 803 of the server management table 800 (step 1902).
[0077]
As a result of the check in step 1901, when it is determined that the telephone line 5 is connected, or when the telephone line 5 is connected in the process of step 1902, a TCP connection (generally on the Internet) is connected to the server specified by the URL. Connection using TCP (Transport Control Protocol), which is one of the communication protocols used in general. However, when the proxy 805 is designated in the server management table 800, a TCP connection is connected to the server designated by the proxy 805 (step 1903).
[0078]
Next, an HTTP request message (request response defined by HTTP) for acquiring the file specified by the URL is transmitted using the TCP connection (step 1904). Then, an HTTP response message (a request response defined by HTTP) is received from the TCP connection (step 1905). After receiving the HTTP response message, the TCP connection is disconnected (step 1906).
[0079]
The telephone line 5 is monitored by a timer, and is disconnected when it is not used for a certain time (for example, 5 minutes).
[0080]
Details of HTTP are described in "HyperText Transfer Protocol-HTTP / 1.0, INETNET-DRAFT, 1995.8".
[0081]
Through the processing described above, information read from the network or package medium can be displayed in a mixed manner as shown in FIG. If the package media does not exist, data can be read from the network. Further, the data 63 (FIG. 10) of the e-mail 6 that is not displayed to the user is also registered in the cache management table 500, so that the contents existing in the package medium 3 can be apparently updated.
[0082]
【The invention's effect】
As described above, according to the present invention, the user can access the difference between the WWW server, the package medium, and the mail without being aware of the data, and the data extracted from the different media are mixedly displayed on the same screen. be able to. For example, by receiving only a small amount of text data from a low-speed network and reading a large amount of data such as video from package media that can be accessed at high speed, a screen with rich expressiveness can be displayed in a short communication time. it can.
[0083]
Further, when the package media storing the desired data is not available, it can be read from the network and displayed.
[0084]
Furthermore, there is an advantage that the user can know at a glance which package media should be used by informing the user of the package media to be inserted into the terminal device.
[0085]
Furthermore, by providing display / non-display attributes in the mail, the contents of the package medium can be apparently updated.
