Next, transmission and reception of mail via the Internet 4 will be described.

The mechanism for sending or receiving a mail via the Internet 4 is very similar to the mechanism for sending a mail such as a postcard. In the case of mail, Write a letter, 2. 2. Post to the post. 3. Transfer between post offices; One letter arrives at the recipient through the four steps of delivering to the mailbox.

In the case of mail via the Internet 4, Write an email on the email sending and receiving program,
2. 2. Press the send button of the mail sending and receiving program.
3. Transfer between mail servers After going through the four steps of pressing the receive button of the mail sending and receiving program,
The email reaches the other party.

The mail sending / receiving program is a program for writing and sending mail to the other party, or receiving the mail sent by the other party. The mail sending / receiving program is also called a mailer, and has a function corresponding to a post and a mailbox.

Most mail sending / receiving programs have an editor function for displaying a mail on a screen or writing a mail. The user operates the mail sending / receiving program to send or receive mail.

As a typical mail sending / receiving program,
Microsoft's OutlookExpress (TM), Qualcomm's Eudora Pro (TM), and free software Becky! InternetMail or Al-Mail32.

The mail server plays the role of a post office, so to speak. The mail server receives the mail sent by the mail sending / receiving program, and sends the mail to the mail sending / receiving program. As a typical mail server program,
There is sendmail (trademark) of Sendmail Corporation.

The mail server has three main roles. First, the mail received from the mail sending and receiving program,
Properly sending to other mail servers. Second
Is to organize and manage mails received from other mail servers by destination (user). Third, sending the managed mail to the mail sending / receiving program in response to a request from the mail sending / receiving program.

The procedure for the mail sending / receiving program to send mail to the mail server is different from the procedure for the mail server to send mail to the mail sending / receiving program, and the communication procedure is different.

The communication procedure is called a protocol. The processing by which the mail sending and receiving program sends mail to the mail server and the processing by which the mail server sends mail to the mail server include SMTP (Simple Mail Transcript).
sfer protocol) is widely used.

The processing for receiving the mail from the mail server by the mail sending / receiving program includes POP3 (Post Office
Protocol Version 3) is widely used.

In the mail server, the port corresponding to SMTP and the port corresponding to POP3 are different from each other. When sending mail, the mail sending and receiving program communicates with the mail server via the port corresponding to SMTP,
When receiving mail, it communicates with the mail server via the port corresponding to POP3.

In the case of mail, a letter sent from a foreign country is stamped for each country passed. Similarly, the mail is also marked with a postmark.

When a mail is transmitted, postmark information is added to the head of the mail body one after another every time the mail passes through the mail server. Since attached to the head, this postmark information is called a header.

The header is mainly composed of three blocks. The block attached to the mail transmission / reception program is arranged in the lowermost part (the part close to the text), and the blocks attached to the mail server are arranged in the two upper parts.

The header stores new information at the top.

The header information attached to the mail sending / receiving program is composed of the same information as the address of the letter. From stores the mail address of the sender, To stores the mail address of the destination, and Subject stores the title.

Of the blocks attached by the mail server, Re
In ceived, a time stamp is stored. form stores the name of the mail server that passed.

The mail server sends this mail
Add Received block. Therefore, the mail server through which the mail has passed can be known by checking the description of the Received block in order from the bottom to the top.

Next, the setting of the mail sending / receiving program will be described. The information that must be set correctly in order to send mail is the e-mail address corresponding to the mail sending / receiving program and the host name of the mail server corresponding to SMTP.

The e-mail address corresponding to the mail transmission / reception program is a source address corresponding to the sender name. When the e-mail address corresponding to the e-mail transmission / reception program is not set, the recipient of the e-mail cannot know the sender, and when the destination is unknown, the e-mail cannot be returned.

The mail transmission / reception program inserts an e-mail address corresponding to the mail transmission / reception program into the From line in the header. The e-mail address corresponding to the mail transmission / reception program is also used as a destination when the other party writes a reply. Depending on the mail transmission / reception program, the destination of the reply can be changed by setting the item of the reply address.

The host name of the mail server to which the mail sending / receiving program sends mail is set as the host name of the mail server corresponding to SMTP. When sending a mail, the mail sending / receiving program sends the mail to the mail server based on the host name of the mail server corresponding to the SMTP. The host name is described as, for example, mailserver.so-net.ne.jp.

The e-mail address and the host name are described based on the domain name. In the domain name, the country name, the type of organization, and the company name are represented by connecting “.”. In a domain name, a larger section is located later.

The e-mail address is the user's name,
It is indicated by attaching "@" as a delimiter and further connecting a domain name.

The host name is expressed by adding "." As a delimiter to the server name, and further connecting the domain name.

The electronic mail address or host name is a unique mail address or host name by being described as described above.

Upper and lower case letters are used for the domain name of the e-mail address and the host name, but these are not distinguished.

Next, transmission of a mail to the mail server by the mail sending / receiving program will be described. The mail sending / receiving program must obtain the IP address corresponding to the host name when sending mail. The IP address is described by a combination of a numeral and “.”, For example, 192.168.0.1.

DNS is a system for converting a host name into an IP address. Internet 4 has several DNs
S server is installed. When a host name is sent to one of the DNS servers, the DNS server returns an IP address corresponding to the host name.

For example, the DNS server 6-1 of FIG. 1 records an IP address aaaa in association with a host name A.

The mail transmission / reception program sends the I / O of the mail server from the DNS server immediately before accessing the mail server.
Ask your P address.

Next, a procedure for transmitting a mail from the mail sending / receiving program to the mail server will be described. The mail sending / receiving program and the mail server send mail from the mail sending / receiving program to the mail server according to the SMTP procedure.

The SMTP procedure is based on TCP (Transmission Control).
l Protocol) setup, calling the mail server, preparing for transmission, notification of destination, transmission of text, confirmation of termination,
And termination of TCP. The processing of calling the mail server, preparing for transmission, notifying the destination, transmitting the text, and confirming the end are all composed of a request from the mail transmission / reception program and a reply from the mail server.

In the SMTP process, the mail transmission / reception program and the mail server communicate with each other using a command statement and a reply code. For example, the command statement “RCPT from:
y@so-net.ne.jp ", the RCPT is a command to notify the mail destination, and the mail destination is y@so-net.ne.jp.
jp.

In the reply code, for example, “Yes”
250. To explain some of the reply codes, 251
Indicates "No such user exists", 450
Indicates "Mailbox is in use" and 451 indicates "
452 indicates "Insufficient resources for processing" and 501
Indicates "The command syntax is incorrect."
Indicates "command not available" and 550 indicates "mailbox does not exist".

The mail has a simultaneous broadcast function. The lifetime broadcast function is a function to send an e-mail with the same text to many people.

For example, if a plurality of mail addresses are described in the To line of the header, the mail sending / receiving program
The process of transmitting the PT command is repeated for each address described in the mail address.

The Cc (carbon copy) line or B
Broadcasting can also be performed using a special header such as a cc (blind carbon copy) line.

When a mail is transmitted using the Cc line or the Bcc line, the recipient of the mail knows that a copy of the mail has been received because his / her address is not described in the To line of the header. be able to.

When an e-mail is sent using the line Cc,
The header stores the mail address of the other party.
When the mail is transmitted using the Bcc line, the mail transmitting / receiving program deletes the Bcc line from the header after transmitting the RCPT command, and transmits the text. Bcc
Sending an e-mail using a line is effective when you do not want to inform the other party of the broadcast destination.

Next, a process in which the mail server searches for a mail server near the destination and transfers the mail server will be described. The process of transferring mail from the mail server to the mail server,
It is executed according to the procedure of SMTP.

In the process of transferring mail from the mail server to the mail server, the mail server sending the mail cuts out the domain name from the mail destination and sends the cut out domain name to the DNS server.

Since the DNS server records the relationship between the domain name and the host name of the mail server as an MX record, the host name of the mail server corresponding to the domain name is
Send the domain name to the mail server that sent it.

For example, the DNS server 6-2 in FIG. 1 records the host name B in association with the domain name BBB.

The mail server having received the host name transmits the host name to the DNS server.

Since the DNS server records the relationship between the host name and the IP address as an A record, the DNS server transmits the IP address corresponding to the host name to the mail server that transmitted the host name.

For example, the DNS server 6-2 in FIG. 1 records the IP address bbbb in association with the host name B.

The mail server that has transmitted the IP address transmits the mail to the mail server corresponding to the domain name of the mail destination based on the above-described SMTP procedure.

The mail server can broadcast mail using a mailing list. When broadcasting mail using a mailing list, the alias function is used.

A mail server utilizing the alias function records a plurality of addresses in advance in groups corresponding to predetermined mail addresses (representative addresses). Upon receiving the mail addressed to the representative address, the mail server retransmits a copy of the mail to all of the plurality of addresses recorded corresponding to the representative address.
The mail server sends mails one after another to the registered mail addresses without rewriting the header.

The mail server corresponding to the domain name stores the received mail in a mailbox called a spool. The mail server manages the mail for each user, and distributes the mail when the receiving button of the mail sending / receiving program of the user corresponding to the destination is pressed.

The reason that the mail server does not send mail to the mail sending / receiving program based on SMTP may be because the device executing the mail sending / receiving program is not operating or is not connected to the Internet 4. It is.

The mail server sends mail to the mail sending / receiving program based on POP3. POP3 procedure is TC
Set up P, call mail server, authenticate user, check mailbox contents, check number of incoming calls,
The process consists of receiving the body text, requesting deletion, confirming termination, and terminating TCP. The process of calling the mail server, authenticating the user, checking the contents of the mailbox, checking the number of incoming calls, receiving the text, requesting deletion, and checking the end are all requests from the mail sending / receiving program and the reply from the mail server. It consists of.

The command text and reply code in POP3 are different from the command text and reply code in SMTP.

In POP3, mail reception processing is not executed unless the user is authenticated by a user ID and password registered in the mail server in advance.

When receiving the mail from the mail server 5-2, the mail transmission / reception program 104 causes the display unit 11 to display, for example, an image shown in FIG. When displaying the received mail, the mail sending / receiving program 104 supplies the received mail to the interpreter 106.

The library 105 includes an interpreter 106
Contains the routines used when executing scripts.

The interpreter 106 is a program plugged into the mail transmission / reception program 104, extracts a script included in the mail, and executes the extracted script. For example, the interpreter 106
In response to the execution of the script, the driver 102-1
A predetermined image is displayed on the display unit 11, and the driver 102-
3 causes the sound reproducing unit 42 to reproduce a predetermined sound.

The interpreter 106 causes the drivers 102-1 to 102-4 corresponding to the display unit 11 or the sound reproduction unit 42 to execute display or sound reproduction, etc. Even if the audio playback unit 11 or the audio playback unit 42 is different, the display or the playback of the audio by the interpreter 106 is executed reliably and accurately.

The interpreter 106 is connected to the display 11
Alternatively, the driver 102-1 to 102-4 corresponding to the device such as the sound reproducing unit 42 executes processing such as display or sound reproduction, so that various devices operating according to the execution contents of the script are stored in the PDA 1. Even if incorporated, the control of the device by the interpreter 106 is executed reliably and accurately.

The mail sending / receiving program 104
When the script is included in the mail to be displayed, the interpreter 106 may be activated and the library 105 may be loaded.

FIG. 10 is a diagram for explaining the structure of the interpreter 106 in more detail. The interpreter 106 includes a syntax analysis module 121, an execution module 122, and an output module 123.

For example, as shown in FIG. 11, when the mail transmission / reception program 104 attempts to display the mail 151, the syntax analysis module 121 receives the mail 151 from the mail transmission / reception program 104 and includes the mail 151 in the received mail 151. The extracted script is extracted and supplied to the execution module 122.

FIG. 12 is a diagram showing an example of the structure of a mail 151 transmitted or received by the PDA 1. When the script is stored in the mail 151, the script is stored after the mail body. When the stored script requires data, the mail 151 stores data necessary for execution of the script by the interpreter 106 following the script.

The syntax analysis module 121 sends the mail 15
When data is stored together with the script in 1, the data is extracted together with the script, and the extracted data is supplied to the execution module 122 together with the script.

FIG. 13 is a view for explaining the flow of processing of the interpreter 106 when the mail 151 stores a script. When the script is extracted from the mail 151, the syntax analysis module 121 supplies the extracted script to the execution module 122.

The execution module 122 that has received the supply of the script executes the script. Output module 12
3 displays an image, outputs sound, or outputs data 171 in accordance with the result of executing the script.
Is stored in the EDO DRAM 34, for example.

On the other hand, when the syntax analysis module 121 does not extract the script from the mail 151 (when the script is not included in the mail 151), FIG.
As shown in (1), the syntax analysis module 121 causes the mail transmission / reception program 104 to execute the subsequent processing, and normal mail processing is executed. At this time, the mail transmission / reception program 104 supplies text data 191 corresponding to the body of the mail 151 to the driver 102-1. The driver 102-1 causes the display unit 11 to display the body of the mail 151 based on the text data 191.

FIG. 15 shows a mail 151 for executing Othello.
It is a figure showing the example of. In the example shown in FIG. 15, the mail 151 is composed of a text and a script. The script included in the mail 151 shown in FIG. 15 is application / x-emma described by the MIME (Multi Purpose Internet Mail Extension) method.

In the mail 151 shown in FIG.
O: "Someone"<someone@sony.co.jp>"~" Othello 2
It is a hand. "" Corresponds to the text, "------ = _ NextPart_000_0
011_01BFA9E7.2EE28580 "to" ---- Next_Part (Wed_Apr_1
9_11: 42: 48_2000_705) ---- "corresponds to the script.

FIG. 16 is a diagram schematically showing execution of a script. Execution of a script is classified into an input unit and an execution unit.

In the input unit, the syntax analysis module 1
With 21, a script is extracted from the mail 151.

The execution section further comprises a data input section, a processing execution section, and an output section. In the data input unit, the execution module 122 includes, for example, the driver 1
At 02-1, an input image is displayed on the display unit 11, and the driver 102-2 controls the input from the touch pad control unit 38.

The input in the data input unit is performed by the execution module 122 by, for example, the tablet, key 22, jog dial 23, sensor, memory stick interface 35, external keyboard, modem, USB interface 36, infrared communication unit 40, or drive 5.
This is executed by controlling the driver corresponding to the second or the like.

In the processing execution unit, the execution module 12
2 executes the processing logic of the script.

In the output section, the output module 123
Corresponds to the processing in the processing execution unit, for example, causes the driver 102-1 to display the image of the processing result on the display unit 11, and causes the driver 102-3 to output the sound of the processing result to the sound reproduction unit 42. Output.

The output at the output unit is output by the output module 123, for example, the display unit 11, the modem, and the audio reproduction unit 4.

FIG. 17 is a diagram showing an example of a script for executing the Othello game. When the script shown in FIG. 17 is read by the interpreter 106, the execution module 122 invokes the onload () method, and as shown in the example of FIG. It is displayed on the display unit 11.

As shown in the example of FIG. 19, when the user inputs a new hand, the execution module 122 obtains the coordinates on the Othello board where the new hand has been input by using the ontap () method. The execution module 12 uses the check () method to determine whether the coordinates corresponding to the new hand satisfies the requirements specified in the Othello rule, and determines that the coordinates do not satisfy the requirements specified in the Othello rule. If it is done, an error message is notified by the confirm () method (an error message is displayed on the display unit 11), and the
Repeat execution of tap () method.

If it is determined that the new hand satisfies the requirements specified in the Othello rules, the execution module 1
In step 22, the face of the frame is updated by the update () method, as shown in FIG. The output module 123
As shown in FIG. 21, by the sendmail () method,
The process of sending the mail to the other party is executed, and the process ends with the exit () method.

Next, mail transmission processing by the PDA 1 executing the mail transmission / reception program 104 will be described with reference to the flowchart of FIG. In step S11, the mail sending / receiving program 104 causes the USB interface 36 to transmit the host name corresponding to the mail server 5-1 to the DNS server 6-1 via the cradle 2, the personal computer 3, and the Internet 4, An IP address corresponding to the mail server 5-1 is obtained from the server 6-1.

The processing of steps S12 to S18 is executed, for example, based on the SMTP procedure.

In step S12, the mail transmission / reception program 104 causes the USB interface 36 to specify the IP address via the cradle 2, the personal computer 3, and the Internet 4 to connect to the mail server 5-1. In step S13, the mail sending / receiving program 104
6 calls the mail server 5-1 via the cradle 2, the personal computer 3, and the Internet 4 (calls a mail server program (for example, sendmail (trademark) or the like) executed by the mail server 5-1).

In step S14, the mail transmission / reception program 104 causes the USB interface 36 to prepare the mail server 5-1 for mail transmission (procedure for transmitting mail to the mail server program executed by the mail server 5-1). Will be notified). In step S15, the mail sending / receiving program 104
Notifies the USB interface 36 of the destination (mail address) of the mail to be transmitted to the mail server 5-1.

In step S16, the mail sending / receiving program 104 causes the USB interface 36 to send mail to the mail server 5-1. Step S17
, The mail transmission / reception program 104 causes the USB interface 36 to confirm completion of processing with the mail server 5-1.

In step S17, the mail transmission / reception program 104 causes the USB interface 36 to disconnect from the mail server 5-1 and the process ends.

As described above, the PDA 1 is connected to the mail server 5-
1 can send an email.

The process by which the mail server 5-1 transfers the mail to the mail server 5-2 is the same as the mail transmission process except for the process of obtaining the host name corresponding to the mail destination. Is omitted.

Next, mail reception processing by the PDA 1 executing the mail transmission / reception program 104 will be described with reference to the flowchart in FIG. In step S31, the mail transmission / reception program 104 causes the USB interface 36 to transmit the host name corresponding to the mail server 5-2 to the DNS server 6-2 via the cradle 2, the personal computer 3, and the Internet 4, An IP address corresponding to the mail server 5-2 is obtained from the server 6-2.

The processing of steps S32 to S40 is executed, for example, based on the POP3 procedure.

In step S32, the mail transmission / reception program 104 causes the USB interface 36 to specify the IP address via the cradle 2, the personal computer 3, and the Internet 4 to connect to the mail server 5-2. In step S33, the mail transmission / reception program 104
6 calls the mail server 5-2 via the cradle 2, the personal computer 3, and the Internet 4.

In step S34, the mail transmission / reception program 104 sends the PDA 1 to the USB interface 36.
Is transmitted to the mail server 5-2 via the cradle 2, the personal computer 3, and the Internet 4 to cause the mail server 5-2 to execute a user authentication process.

In step S35, the mail sending / receiving program 104 causes the USB interface 36 to check the contents of the mail box (where the mail addressed to the user of the PDA 1 is stored) to the mail server 5-2.

In step S36, the mail transmission / reception program 104 sends the PDA 1 to the USB interface 36.
The number of incoming e-mails to the user is transmitted to the mail server 5-2, and the number of incoming e-mails is received.

In step S37, the mail sending / receiving program 104 causes the USB interface 36 to send the mail addressed to the user of the PDA 1 to the mail server 5-2 and to receive the sent mail. In step S38, the mail transmission / reception program 104 causes the USB interface 36 to request the mail server 5-2 to delete the mail addressed to the user of the PDA 1. Mail server 5-2
Deletes the email addressed to the user of PDA1.

In step S39, the mail transmission / reception program 104 causes the USB interface 36 to confirm the end of processing with the mail server 5-2.

In step S40, the mail transmission / reception program 104 causes the USB interface 36 to disconnect from the mail server 5-2, and the process ends.

As described above, the PDA 1 has the mail server 5-
From 2, it is possible to receive a mail addressed to the user of the PDA1.

Next, the mail sending / receiving program 104 and the interpreter 106, which are executed when the mail sending / receiving program 104 displays the received mail, are executed.
The script processing of the PDA 1 will be described with reference to the flowchart of FIG. In step S51, the mail sending / receiving program 104 reads the received mail 151.

In step S52, the mail sending / receiving program 104 determines whether or not the read mail 151 includes a script. If it is determined that the script is included, the process proceeds to step S53, where the interpreter 106 to start. Mail sending and receiving program 1
04 interprets the read mail 151 into the interpreter 106
To supply.

Note that the interpreter 106 may be activated in advance together with the mail transmission / reception program 104.

At step S54, the interpreter 1
The syntax analysis module 121 of 06 extracts a script included in the mail 151 based on the description of the mail 151. In step S55, the execution module 122 of the interpreter 106 executes the extracted script.

In step S56, the interpreter 1
The output module 123 executes display or audio output processing according to the result of the execution of the script. In step S57, the mail transmission / reception program 104 ends the interpreter 106, and the process ends.

If it is determined in step S51 that the script is not included, the processing corresponding to the script is not necessary, so that steps S53 to S5
7 is skipped, and the process ends.

As described above, when the script is included in the mail 151, the PDA 1 activates the interpreter 106 and executes the processing corresponding to the script.

Note that the processing in step S52 is performed by the syntax analysis module 12 of the interpreter 106 that has been started in advance.
1 may be executed.

Next, the Othello process, which is a more specific example of script execution, will be described with reference to the flowchart in FIG. In step S71, the mail sending / receiving program 104 reads the received mail 151.

In step S72, the mail sending / receiving program 104 activates the interpreter 106. In step S73, the output module 123 of the interpreter 106 causes the display unit 11 to display the Othello board and the frame.

In step S74, the execution module 122 determines whether or not a new hand has been input. If it is determined that no new hand has been input, the execution module 122 proceeds to step S74 until a new hand is input. And the process of the determination is repeated.

If it is determined in step S74 that a new hand has been input, the process proceeds to step S75, where the execution module 122 reads the coordinates of the new hand (indicating the position on the Othello board). In step S76, the execution module 122 determines whether the new hand satisfies the requirements specified in the Othello rule, and determines that the new hand satisfies the requirements specified in the Othello rule. If so, the flow advances to step S77 to place a frame at the position of the Othello board corresponding to the new hand.

In step S78, the execution module 122 updates the face of the frame, such as turning over a predetermined frame. In step S79, the output module 123
Displays the Othello board and the frame on the display unit 11.

In step S80, the output module 123 causes the USB interface 36 to communicate a new hand with the other party. In step S81, the mail sending / receiving program 104 ends the interpreter 106, and the process ends.

If it is determined in step S76 that the new hand does not satisfy the requirements specified in the Othello rule, the process proceeds to step S82, where the output module 12
3 displays an error on the display unit 11 to notify the user of the error, and the procedure returns to step S74 to repeat the process from the input of a new hand.

As described above, the PDA 1 executes the Othello process based on the script included in the mail 151.

As described above, when the user attempts to read the mail 151, the PDA 1 executes the action desired by the sender of the mail 151. When the user does not read the mail 151, the PDA 1 does not execute the script included in the mail 151, so that the processing load of the script can be minimized.

Since the PDA 1 can execute various processes corresponding to the description of the script only by executing the interpreter 106, the data attached to the mail is compared with the case where the data is attached to the mail and transmitted. There is no need to store a large number of application programs corresponding to the types.

Further, since the interpreter 106 executes the script, if the interpreter 106 is securely implemented, the processing can be executed more safely than when the execution program attached to the mail is executed as it is. .

4 is converted into coded image data by performing compression coding according to a predetermined coding method such as
8

At this time, the camera-equipped digital mobile phone 301 simultaneously transmits the sound collected by the microphone 312 during the imaging by the CCD camera 307 to the demultiplexing unit 358 as digital sound data via the sound codec 360.

[0226] The demultiplexing section 358 includes the image encoder 35.
Coded image data and audio codec 3 supplied from
The multiplexed data is multiplexed with the audio data supplied from the control unit 60 by a predetermined method, and the resulting multiplexed data is multiplexed with the modulation / demodulation circuit unit
Then, the signal is subjected to spread spectrum processing at 9 and subjected to digital-analog conversion processing and frequency conversion processing at the transmission / reception circuit section 364 and then transmitted via the antenna 305.

On the other hand, in the data communication mode, for example, when receiving data of a moving image file linked to a simplified homepage or the like, the digital cellular phone 301 with a camera receives the data received from the base station via the antenna 305. The signal is subjected to spectrum despreading processing in the modulation / demodulation circuit section 359, and the resulting multiplexed data is sent to the demultiplexing section 358.

The demultiplexer 358 separates the multiplexed data into coded image data and audio data,
, The encoded image data is supplied to the image decoder 357, and the audio data is supplied to the audio codec 360.

[0229] The image decoder 357 generates reproduced moving image data by decoding the encoded image data by a decoding method corresponding to a predetermined encoding method such as MPEG2 or MPEG4, and outputs this through the LCD control unit 356. It is supplied to the liquid crystal display 309. Thereby, the camera-equipped digital mobile phone 301 displays, for example, the moving image data included in the moving image file linked to the simplified homepage.

At this time, the audio codec 360 simultaneously
After converting the audio data into an analog audio signal, this is supplied to the speaker 308. Thereby, the camera-equipped digital mobile phone 301 reproduces, for example, audio data included in the moving image file linked to the simplified homepage.

In this case, similarly to the case of the e-mail, the camera-equipped digital mobile phone 301 records the received data linked to the simplified homepage or the like on the memory stick 11 via the storage / reproduction unit 363 by the operation of the user. It is possible.

Note that the present invention is not limited to the PDA 1 and the camera-equipped digital cellular phone 301, and transmits or receives mail such as a notebook personal computer, a PHS (Personal Handyphone System) terminal device, or a car navigation system. It can be applied to all devices.

Next, a more detailed configuration of the interpreter 106 will be described.

FIG. 30 is a diagram showing an example of a more detailed configuration of the interpreter 106.

The mail parser 502, decoder 503, parser 505, data constructor 517, encoder 518, and mail generator 519 shown in FIG.
Corresponding to the syntax analysis module 121.

The script interpreter 506 in FIG.
Authentication encryption unit 507, resource access manager 50
8 and the storage module 511 correspond to the execution module 122 in FIG.

The I / O (Input / Output) module 510 in FIG. 30 corresponds to the output module 123 in FIG.

The mail transmission / reception program 104 supplies the mail 151 to be opened to the mail parsing unit 502 via the mail transmission / reception program plug-in interface 501, or acquires the mail 151 generated from the mail generation unit 519. I do.

The mail syntax analysis unit 502 analyzes the syntax of the mail 151 supplied from the mail sending / receiving program 104 via the mail sending / receiving program plug-in interface 501, and extracts a script and data from the mail 151. Mail parsing unit 502
Supplies the script and data extracted from the mail 151 to the decoder 503.

A script is a type of program consisting of a series of instructions in which a processing procedure is described by character codes such as alphanumeric codes.

[0241] The decoder 503 decodes, for example, data encoded by a system such as Base64. Base64
Is an encoding method of binary data for converting data or a program into a sequence of 64 types of ASCII codes in order to transmit data or a program via a network transmitting only 7-bit data.

Note that the decoder 503 may decode an encoded script.

The decoder 503 is connected to the interface 50
4 to supply the script to the parsing unit 505,
The decrypted data is supplied to the script interpreter 506.

The syntax analysis unit 505 replaces a predetermined character string included in the script with an intermediate code that can be processed by the script interpreter 506.
Here, when the intermediate codes are roughly classified, generally, (1)
Lexical columns, such as lexical analysis results and generated lexical columns,
(2) A tree structure such as a parse tree or syntax tree generated as a result of parsing, a tree structure such as a Polish notation, and (3) a class that is close to a machine language such as a virtual machine code called a triple or quadruple. However, in this specification, this intermediate code is used in the meaning of a parse tree.

In the Java language, the above (3) is called "byte code".

The intermediate code is an intermediate format code that is temporarily created for convenience in the process of converting the original source code into the final executable format in the software program. By finely separating the conversion process from the source to the target in this way, it becomes easy to make the language processing system correspond to a plurality of platforms (targets).

For example, in Java, the source code is
Once converted to an intermediate code called bytecode,
The converted intermediate code is stored on the WWW server. The WWW server sends this bytecode to the WWW browser on the client side and sends it to the Java VM (Java Virt
ual Machine) interprets and executes the bytecode.
In this case, the Java VM absorbs differences between platforms (differences between CPUs and operating systems), so the bytecode itself does not depend on a specific platform. In this way, a platform-independent program environment is realized in Java while reducing the load imposed on execution (conversion from bytecode to executable code).

Also in other high-level language compilers, instead of directly converting a source code into an execution program (usually a binary code that can be interpreted by a CPU),
Convert to intermediate code with a higher level of abstraction than the actual machine (there is no need to worry about the limitations of the actual machine architecture, so it is easier to optimize the code, etc.), and then the final executable In many cases, a method of generating a binary code is used.

The syntax analyzer 505 supplies a script in which a predetermined character string is replaced with an intermediate code to the script interpreter 506.

The script interpreter 506 supplies the script to the authentication encryption unit 507, and the script
7 makes the script determine the validity.

The authentication encryption unit 507 calculates a hash value corresponding to the script by applying a hash function such as MD (Message Digest) 5 to the script. The authentication encryption unit 507 determines whether the calculated hash value and the data for authentication included in the script are the same.

FIG. 31 shows an example of a mail 151 including a script storing data for authentication.

In the mail 151 shown in FIG. 31, "<S
IGNATURE> ”and“ </ SIGNATURE> ”are data for authentication such as“ 347a9d8684ab96533fb6b51906fdacf9 ”.

An electronic signature or a certificate may be stored in the mail 151, and the authentication encryption unit 507 may be authenticated based on the electronic signature or the certificate.

If it is determined that the calculated hash value and the data for authentication are the same, the authentication encryption unit 507 converts the data indicating that the script is valid, since the script has not been altered, into the script. It supplies to the interpreter 506.

If it is determined that the calculated hash value and the data for authentication are not the same, the authentication encrypting unit 507 transmits data indicating that the script is not valid, since the script has been altered, to the script interpreter 5.
06.

The script interpreter 506 sends the data indicating that the script is not valid to the authentication encryption unit 50.
When supplied from 7, do not execute the script.

The script interpreter 506 sends data indicating that the script is valid to the authentication encryption unit 50.
7, the script is executed based on the data supplied from the decoder 503.

6, the result of input / output, storage or reading of information, or access of an external application program is supplied.

In step S523, the script interpreter 506 determines whether or not to transmit the execution result of the script by e-mail based on the operation of the user or the description of the script, and transmits the execution result of the script by e-mail. If it is determined to transmit, step S524
The script interpreter 506 supplies the data constituting unit 517 with data that is attached to the electronic mail and needs to be formed into a predetermined format, such as data indicating the execution state of the script.

[0338] In step S525, the data forming unit 517 shapes the data supplied from the script interpreter 506 into a predetermined format. Data configuration unit 517
Supplies the molded data to the encoder 518 via the interface 504.

[0339] In step S526, the script interpreter 506 supplies a script or data to be attached to the electronic mail to the encoder 518 via the interface 504. The data that the script interpreter 506 directly supplies to the encoder 518 is data that does not need to be formed in the data configuration unit 517.

In step S527, the encoder 5
