FIG. 10 is a diagram showing the structure of the interactive video transmitting means 108 according to the embodiment of the present invention.
The interactive video transmission means 108 is composed of terminal connection communication means 1001, file transfer means 1002, Internet server connection communication means 1003, terminal request analysis means 1004, and file storage means 1005.

The terminal connection communication means 1001 communicates with the interactive video reproduction means 106 via the communication medium 107 to receive a request and send a result. The content received in the request is mainly a URL, and the transfer protocol (HTTP protocol, FTP protocol, original protocol, etc.) and the target file (HTML format file, multimedia data, etc.) are received. Send the result according to your request
Sends HTML files and multimedia data.

The terminal request analysis means 1004 analyzes the request acquired from the terminal connection communication means 1001. Generally, the URL of the request content is, for example, "https://www.WorldCookToday.xxx.xxx/n
"ews.htm", a transfer protocol, an Internet server name, and a file name are designated. The terminal request analysis unit 1004 delivers the analysis result to the file transfer unit 1002.

The file transfer means 1002 refers to the analysis result of the terminal request analysis means 1004, and the target internet server and file are the interactive video transmission means 108.
If it exists, the file is read from the file storage means 1005 and delivered to the terminal connection communication means 1001 by a specified protocol. If it does not exist, it requests the Internet server connection communication means 1003 to acquire the desired file.

The internet server connection means 1003 searches for a target internet server via the internet 109, acquires a target file from the server, and delivers it to the file transfer means 1002.

FIG. 11 is a diagram showing the configuration of the interactive video transmitting means 108 according to another embodiment of the present invention. The interactive video transmission means 108 is a terminal connection communication means 1001, a file transfer means 1002, an internet server connection communication means 1003, a terminal request analysis means 1004, a file storage means 1005, an HTML document generation means 1101, an encryption analysis means.
1102, user information storage means 1103, title information storage means
Consists of 1104. Among these components, the terminal connection communication means 1001, the file transfer means 1002, the internet server connection communication means 1003, and the file storage means 1005 are the same as those described in FIG. 10, and the description thereof is omitted here.

The terminal request analysis means 1004 has the following functions in addition to the functions described in FIG.

When the request content includes encrypted information, the terminal request analysis means 1004 uses the cipher analysis means 1102 to decrypt the code.

When the request content includes requester identification information (user ID), the terminal request analysis means 1004
If the user information storage unit 1103 is referred to, and user information corresponding to the user ID is stored in advance, various services such as an information providing service and a connection charge discount service are performed using the information. Further, regardless of the presence or absence of various services, the storage content of the user information storage unit 1103 is updated according to the content requested by the user. For example, the information is updated together with the user ID by using the time information of the user request, the name of the Internet server and the document that the user wishes to access, and the like.

Further, when the request content includes the disc identification information (disc ID) of the optical disc medium 101 used when the requester issued the request, the terminal request analysis unit 1004 includes the title information storage unit 1104. When the service information corresponding to the disk ID is stored in advance, various services such as an information providing service and a connection charge discount service are performed according to the information.
Further, the content stored in the title information storage unit 1004 is updated according to the content requested by the user, regardless of the presence or absence of various services.

When performing various services, the terminal request analysis means 1004 creates an HTML document using the HTML document creation means 1101 as necessary, and creates the created HTML document via the file transfer means 1002. Send out. As the content of the HTML document to be created, an HTML document for referencing a file recorded in the file storage unit 1005, an HTML document for referencing the Internet server 110, or an HTML document acquired from the Internet server 110 is modified. It is assumed to have been done.

FIG. 12 is a diagram showing an HTML file, and a method of using the interactive video transmitting means 108 according to the present invention will be described with reference to this diagram. 12 is a replacement of PAGE001.HTM shown in FIG. 6 and is recorded on the optical disc medium 101. The difference from FIG. 6 is line 120.
In 1. In Fig. 6, it is defined that when "Event guide" is selected, the page moves to the "CM corner" page (AD001.HTM), and from that "CM corner" the target "Event guide" page (TOPIC. HTM).

The row 1201 in FIG. 12 indicates “http: // ww
"w.ad.server.xxx.xxx/" defines a protocol name and a server name, and this server indicates the interactive video transmitting means 108. Subsequently, the part described as "cgi-bin / connect?" As the target file name means to execute the program named "connect" recorded in the directory "cgi-bin" of the interactive video transmission means 108. ing. This program "connect" analyzes the parameters described after "?" (Using the terminal request analysis means 1004) and responds to the request.
Create an HTML document (HTML document creating means 1101).

The parameters described in the line 1201 are a plurality of "variable name = variable value" separated by "&", and two parameters are defined here. The first parameter definition describes the URL of the target transition destination. Here, "http: /www.WorldCookToday.xx
x.xxx/topic001.htm ”is shown. This URL points to the "event guide" page (TOPIC001.HTM) described in FIG.

The terminal request analysis means 1004 predicts that the user wants to transit to TOPIC001.HTM by analyzing this parameter.

The page TO that the user wants to change as it is
When PIC001.HTM is acquired from the Internet server 110 and transmitted, the page directly goes to the "event guide" page without going to the "CM corner" as described in FIG.

On the contrary, if AD001.HTM shown in FIG. 7 is sent to the user, the "CM corner" is forcibly inserted for 10 seconds, and TOPIC001.HTM is sent continuously. In this case, the HTML document creating means 1101 defines TOPIC001.HTM as the URL of the transition destination shown in line 701 of FIG.

Whether or not the CM is inserted as described above is
It depends on the content of the service. If the connection fee for the interactive video reproducing means 106 is to be provided free of charge, including telephone charges, it may be necessary to insert an advertisement compulsorily.
It may not be necessary to insert an advertisement for a user who can expect mail-order sales or for a user who obtains the optical disc medium 101 for a fee.

In the present invention, a keyword starting with “key =” is defined as a parameter of the line 1201 as a key for judging the service providing mobile such as the advertisement insertion. The meaning of this keyword is that the name of the target Internet server and the name of the file are encrypted. The owner of the optical disc medium 101 can send this keyword by using PAGE001.HTM recorded on the optical disc medium 101, but a person who is not the owner can generate and send this encrypted keyword. Have difficulty.

The encryption algorithm in this figure is
Since a method in which the alphabet is shifted by one character (generally called a Caesar cipher) is used, it is relatively easy to estimate a keyword, but actually, an encryption method with a higher security level is used. For example, DES (Dat
a Encryption Standard) and Hitachi's Multi and other encryption methods, and other encryption methods.

Further, here, the encrypted URL is given as a keyword, but any other information such as the user ID, the reproduction device ID, the disc ID, etc. may be encrypted.

FIG. 13 shows another example of an HTML file, and a method of using the interactive video transmitting means 108 according to the present invention will be described with reference to this drawing. FIG. 13 shows FIG.
It is a further extension of PAGE001.HTM described in 1. and is recorded on the optical disc medium 101. The difference from FIG. 12 is in line 1301. In Fig. 12, as parameters described after "?" Analyzed by the program "connect", the first parameter definition is the target URL of the transition destination, and the second parameter definition is the URL of the transition destination. Although the encrypted keyword is defined, in line 1301, the third parameter definition further defines the user ID, and the fourth parameter definition defines the disk ID.

As described above, by specifying the user and the type of the disk, it is possible to perform detailed services such as an information providing service and a charge discount service according to the connection tendency of the individual while referring to and updating the user information storage means 1103. .
Further, similarly, it is possible to provide information related to the information field of the title while referring to and updating the title information storage means 1104, electronic settlement service such as mail order, and the like.

However, the disc ID can be fixed in advance when the optical disc medium 101 is produced, but in order to fix the user ID in advance, it is necessary to investigate individual user IDs before production. There is a problem, especially when using mass-duplication media such as CD-ROM.

In such a case, the interactive video reproducing means 106 transmits without adding the user ID parameter. Upon receiving the URL in which the user ID is not inserted, the interactive video transmitting means 108 returns an HTML document as shown in FIG. 14 to the interactive video reproducing means 106 so as to request the transmission of the user ID.

FIG. 14 asks to send the user ID
This is an example of an HTML document. Line 1401 has tags that start with "META". "HTTP-EQIIV =" SendUserID "" is a description that requests to send back the user ID.
ENT = "URL = http: //www.ad.server.xxx.xxx/connect? Id = 0
The part "001 & usr =""is the request content to send the user ID to the" connect "program of the specified internet server. The first parameter “id = 0001” is the temporary ID assigned to this user by the interactive video transmitting means 108, and the second parameter “usr =” is the interactive video reproducing means 106 that inserts the user ID at the end. Since then.

Interactive video transmission means 108 is a temporary ID
When issuing ",""url=""key=","ds
The contents of parameters such as “k =” are stored.

In response to this request, the interactive video reproducing means 106 determines the user ID by a method such as asking the user to input the user ID, or reading out the terminal ID stored in the reproducing means itself. , `` Usr = 61
Generate a parameter such as "1947808".
