Brief Patent Description - Full Patent Description - Patent Application Claims CROSS-REFERENCE TO RELATED PATENT APPLICATIONS [0001] This application is a division of application Ser. No. 09/983,449, filed Oct. 24, 2001, now pending, and related to two concurrently filed applications entitled LARGE CAPACITY DATA SALES SERVER AND RECORDING MEDIUM RECORDING PROGRAM THEREOF (Attorney Docket No. 072982-0273) and LARGE CAPACITY DATA SALES MEDIATION SERVER AND TERMINAL (Attorney Docket No. 072982-0275) and based on Japanese Patent Application No. 2000-332119, filed Oct. 25, 2000, by Koji Maeda. This application claims only subject matter disclosed in the parent application and therefore presents no new matter. BACKGROUND OF THE INVENTION [0002] The present invention relates to large capacity data sales method and system, and large capacity data sales mediation method and system for selling data of a large capacity such as animation data. DESCRIPTION OF THE RELATED ART [0003] In recent years, a technology (service) for distributing data such as music via a network as the Internet is rapidly becoming widespread. For instance, an incoming tone distribution service for a portable telephone is quite successful in terms of business. [0004] According to the above conventional technology, however, time required for transmitting data is extremely long in the case of distributing or selling large capacity data of a data amount (capacity) far larger than music data, such as animation data, map data and dictionary data is conducted. For this reason, communication costs and so on also become huge. In addition, sending and receiving data of such large amount put an enormous load on a communication environment. [0005] Therefore, distribution and sales of data via the network is effective for data of a small capacity such as melody data for incoming tone as in the above conventional technology, but it is not practical in the case of large capacity data such as animation data. [0006] On the other hand, storage media capable of storing large capacity data as animation data are currently quite inexpensive. For instance, a DVD-ROM, a typical one of such storage media is capable of storing large capacity data such as movies, and may be even attached to a magazine or the like nowadays. [0007] Moreover, a CD-ROM, which is becoming popular as a storage medium for storing large capacity data in spite of its smaller capacity than the DVD-ROM, are occasionally distributed for free. [0008] Thus, it is expected that the animation data will be sold and distributed by such storage media rather than a communication line in the future as well. [0009] As for a sales and distribution method of the animation data using such storage media, however, various problems are pointed out. A first problem is that this large capacity data may be distributed to a number of unspecified persons. A second problem is that this large capacity data becomes expensive. A third problem is that much labor and costs are required therefor. [0010] The first problem is a problem of so-called unauthorized copies. For instance, a variety of technologies for preventing unauthorized copies are installed on the DVD-ROM, but these unauthorized copy preventing technologies are uniformly provided as a standard of the DVD-ROM, and so their level relatively become lower and vulnerable as the technology level is ever rising. [0011] The second problem arises because such a sales method only allows assignment of the large capacity data. To be more specific, it is very expensive to sell and/or distribute storage media in which the large capacity data is stored because recovering the storage media is difficult as compared with the cases of renting them (assignment with a deadline). [0012] The third problem arises because large capacity media must be sold by way of an actual distribution channel. For instance, a still popular sales method of delivering an animation medium to a predetermined retailer and collecting a price from a purchaser requires a lot of labor and costs. While comprehensive efficiency of this sales method is better than said cases of distributing and/or selling the large capacity data such as the animation data by using the aforementioned network, it is extremely inefficient if compared to a distribution method via a network of small-scale data such as the above music data. [0013] On the other hand, the first conventional technology disclosed in Japanese Patent Publication No. HEI 03-3290 discloses an image reproduction system constituted so that an image reproduction device has mode switches for respective mode functions, and a recording medium with an inserted key code corresponding to one of the modes of the above mode switches is provided so as to operate the image reproduction device only in the case where, on setting the recording medium on the above image reproduction device, the mode function of the above mode switch corresponds to the key code of the recording medium. [0014] As for this first conventional technology, however, it is just that the image reproduction device operates only in the case where the key code of the recording medium corresponds to the mode function of the above mode switch, and as the applicant who proposed the first conventional technology points out, it does not show a countermeasure against the above-mentioned problem of unauthorized copies even though it can be used in order not to show children an educationally undesirable VTR, for instance. In addition, it does not indicate any countermeasure against the above second and third problems. [0015] The second conventional technology disclosed in Japanese Patent Application Laid Open No. HEI 08-235759 discloses a disk reproducing device for reproducing an image program recorded on a disk on which an image display prohibition process is performed by correspondence of a lock code, having a power switch for turning on and off the power of the device proper, and a means for storing an image display state and a reproduced position address when the above described power switch is turned off, a checking means for checking a previous image display state from the above described means for storing when the above described power switch is turned on, and means for maintaining an image display prohibition state in the case where, as a result of the check, it is verified that the image display prohibition was cancelled to display images last time due to correspondence of the lock code. [0016] However, this second conventional technology is a technology for a problem that, in a parental process technology for rendering a part or all of a video tape, a video disk and so on irreproducible without inputting a specific key code, a player having a memory play function for, if switched off and then switched on, starting reproduction from a scene reproduced when switched off last time has the memory play function also performed to the video disk having undergone the parental process, and so it is not a technology for solving the problems described above. [0017] The third conventional technology disclosed in Japanese Patent Application Laid-Open No. HEI 10-334048 discloses a method of sending predetermined chargeable information on a WWW server to a user side in response to a request from a personal computer on the above user side on which a WWW browser of the Internet is mounted; the above method having: a first password sending stage for inputting a first password on the above WWW browser from the personal computer on the above user side and sending the inputted first password to the above WWW server; a second password returning stage for the above WWW server to issue a second password according to the above first password and return the above second password to the user browsing the above WWW browser; a password notifying stage for the above user to dial a number of a center device of a videotex communication network displayed on the above WWW browser and notify the above center device of the above first password and the second password acquired by way of the above Internet and also notify the above WWW server or a server different from the above WWW server and having a function of governing an accounting check of the WWW server of the above first password and the second password received by the above center device; a password checking stage for the above WWW server or the above different server to check the above first password and the second password received from the above user via the above center device against the above first password received from the above user via the above Internet and the above second password issued by the above WWW server; and a chargeable information sending stage for sending the above predetermined chargeable information from the above WWW server to the personal computer on the above user side in the case where the check results in the above password checking stage correspond. [0018] However, this third conventional technology is a technology for handling the chargeable information that is difficult to handle on the WWW server by using the videotex communication network, and so it is not a technology for solving the problems described above. [0019] The fourth conventional technology disclosed in Japanese Patent Application Laid-Open No. HEI 11-225324 discloses a technology related to a reproduction system for reproducing AV information recorded on a storage medium and outputting it on a display device, the above system having: a means for storing resource use information for, to use related information related to predetermined stream information included in the above described AV information, connecting to a resource having said related information, the above resource use information having a plurality of definitions of the same related information based on predetermined system attribute information; and control means for, when reproducing the above described AV information, selecting the above described resource use information determined based on the above described system attribute information to process the above described related information acquired from the resource and display it on the screen of the above described display device. [0020] However, this fourth conventional technology is a technology for, in a system for reproducing the AV information from a storage medium such as the DVD, acquiring related information related to predetermined stream information by using resources of a computer network in addition to ordinary reproduction of a title, and so it is not a technology for solving the problems described above.
