BACKGROUND OF THE INVENTION
The present invention relates to a digital content distribution system to distribute contents, and in particular, to a technology efficiently applicable to a digital content distribution system in which an original document such as a book is digitized into a digital content and the content digitized is distributed from a content database center to stores such that a digital content selected by a customer is sold in the stores.
Thanks to the spread of the Internet, electronic commerce has been developed and hence attention has been attracted to sales of a digital content which can be sold and delivered through a network. Additionally, it has been expected that the contents of information (such as novels, comics, music, and games) which have been sold as articles or package media through existing distribution routes are digitized and are distributed and sold through networks.
In accordance with the background art to sell the digitized content, there has been actually developed business, for example, mail-order selling of various contents and download of a digital content itself via a network at an electronic mall site of the Internet, a service of a terminal at a store such as a convenience store to copy a content desired by a customer from a storage media onto a supply media, and a service to deliver information using a telephone service number.
JP-A-10-254850 describes an information system and an information generating method for use with the system which distributes information generated or edited using information items dispersed in a network. In the system, new information is generated using information items dispersed in the network and is distributed via the network. This facilitates editing of information such as generation and modification thereof according to processing conditions such as an audiovisual environment and a generation environment of information.
Distribution and sales using paper as media play at present a central role in the distribution and sales of contents. In the distribution via such paper media, a print format of the contents on sheets of paper and a bundling form of the sheets influence a way of distribution and an audiovisual way, which forms the present culture. There is consequently needed a digital content distribution system in which the way of distribution and the audiovisual way are preserved and the culture accumulated is inherited and the contents using the paper media are digitized into digital contents to change the existing system to a system in which the contents are distributed and sold via a network. The digital content distribution system thereby solves distribution problems of the existing distribution media such as the environmental problems, the problem of the latest one of the contents, the problem of the returning and discarding of goods, and the problem of distribution cost.
In the background art to sell a digital content, although the selling of the digital content itself is carried out, the content is not distributed in the form of digital data entirely through the digital content distribution system. This leads to a problem that a digital content generated through the digitization cannot be immediately distributed to a store to be sold to a customer.
That is, in the background art to sell a digital content, an ordinary distribution such as delivery of a compact disk read-only memory (CD-ROM) in which a digital content is stored appears at an intermediate point of the digital content distribution system. Consequently, there exists a problem that a period of several days is required for the delivery of a digital content of a new item and the delivery of a digital content ordered by a customer.
When a digital content is sold via a network, the digital content is beforehand copied onto a recording media. However, in the background art above, there has not been clearly established a system in which the license fee of the digital content is collected according to the number of copies to pay the collected amount to the content holder. This consequently leads to a problem of possibility that the license fee is not paid to the content holder according to the number of copies sold.
For the content already distributed, the configuration itself in which the user listens to or views the content is an important point. Namely, since items distributed in the form of publications have a style of books, there has already been established a method to find out books, and the readers have a manner to read a book in a page-by-page fashion by turning over pages.
However, in the related art to sell a digital content, since the digitization is not achieved to reproduce with possible fidelity to the configurations such as the appearance of articles of publications and CDs actually distributed, the appearance of the original book of the content considerably varies from that of the digital content attained by digitizing the original book in some cases. This leads to a problem of difficulty in the handling of the digital content in the same way as for the actual item. For example, when only text data of a book is inputted to generate an electronic book, since information of appearance of the book such as a cover and a backbone of the book is lost, it is difficult to search for the electronic book including only the text data in a way similar to that used to search for a book which a customer just happened to see in an advertisement or to search for a well-known book in a store by visually checking its cover and backbone.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a technology capable of distributing the digital content at a high speed, thereby solving the problem above.
Another object of the present invention is to provide a technology capable of distributing a license fee to a content holder according to the number of digital contents sold.
In accordance with the present invention, there is provided a digital content distribution system to distribute a digital content via a network in which digital contents are distributed via the network and are sold to customers and a license fee is distributed to a content holder of the contents according to the number of contents sold.
In a digital content distribution system of the present invention, an original document of a content is received from a content holder who possesses the content and then the content is digitized in a digitization center into a digital content. The digital content generated is acknowledged and then is accumulated in a content database center.
The content database center generates a distribution schedule to distribute digital contents and sends therefrom a plurality of digital contents to shops or stores according to the distribution schedule. It may also be possible to classify a plurality of stores into particular groups such as a group of stores of a particular chain and a plurality of distribution management centers are installed to manage distribution to stores of the respective groups such that the distribution is carried out via these centers.
The store copies on a media or downloads in a viewer device a particular digital content selected by a customer from the distributed digital contents and sells the content to the customer.
If the digital content requested by the customer has not been distributed to the store, the store transmits a distribution request via the distribution management center to the content database center for an on-demand distribution of the digital content. When the digital content distributed on-demand passes through the distribution management center, the content is cached in the content database center. When the same distribution request is issued from another store managed by the distribution management center, the content is distributed on-demand from the distribution management center to the store of the distribution request without using the content database center.
In each store, when a digital content is sold, the contents of the sale are stored in a magnetic disk device to collect sales information. The content database center receives via the distribution management center the sales information collected in the respective stores, calculates the license fee by totaling associated amounts, and remits the license fee to the content holder.
As above, in accordance with the digital content distribution system of the present invention, the distribution of digital contents from the content database center to the stores is conducted entirely via the network and hence can be achieved at a high speed.



The objects and features of the present invention will become more apparent from the consideration of the following detailed description taken in conjunction with the accompanying drawings.

FIG. 7 is a flowchart showing a processing procedure of digitizing section 210 of the embodiment. After having received an original book from a publisher in step 701, digitizing section 210 of digitizing device 100 digitizes in step 702 the received original book to generate an electronic book and information for goods of the electronic book. In step 703, digitizing section 210 sends the digitized book thus digitized to recognition device 110 of the publisher and then awaits a response from recognizing section 310.
FIG. 8 is a flowchart showing a processing procedure of recognizing section 310 of the embodiment. Recognizing section 310 of recognition device 110 receives in step 801 the electronic book generated by digitizing device 100 then displays in step 802 the contents of the received electronic book on display 305.
In step 803, recognizing section 310 receives an input from an operator. If the contents of operation inputted from the operator indicate recognition of the contents of the electronic book, processing goes to step 804 to transmit a recognition message to digitizing device 100. If the contents of operation inputted from the operator indicate replacement of the electronic book, processing goes to step 805 to transmit to digitizing device 100 the contents of replacement inputted from the operator.
Instep 704, digitization section 210 of digitizing device 100 examines the contents of a response message from the publisher. If replacement is required for the electronic book generated in step 702, digitizing section 210 conducts processing of replacement in step 705 and then control returns to step 702 to again execute processing beginning at the digitization. If the contents of the electronic book generated in step 702 is recognized, digitizing section 210 sends the electronic book to content database section 410 of content database device 120 in step 706.
FIG. 9 is a flowchart showing a processing procedure of content database section 410 of the embodiment. In step 901, content database section 410 of content database device 120 receives an electronic book and information for goods of the book which have been sent from digitizing device 100. In step 902, section 410 accumulates the electronic book and the information for goods in a database of magnetic disk device 403. Thereafter, in step 903, section 410 executes database update processing such as update of an index.
Next, description will be given of processing in the embodiment of the digital content distribution system in which an electronic book accumulated in content database device 120 is first distributed to vending device 140 to be thereafter sold.
FIG. 10 is a flowchart showing a processing procedure of distribution control section 411 of the embodiment. In step 1001, distribution control section 411 of content management device 120 generates a distribution schedule to distribute an electronic book to vending device 140. In step 1002, section 411 reads out an electronic book and information for goods of the book distributed according to the distribution schedule.
In step 1003, section 411 sends the distribution schedule generated and the obtained electronic book and information for goods to distribution management device 130 to instruct device 130 to distribute the electronic book according to the distribution schedule. In step 1004, section 411 makes a check, for each distribution management device which conducts the distribution processing according to the distribution schedule, to determine whether or not the distribution instruction is completed for the device. If the instruction has not been completed to the device, control returns to step 1003 to continue the processing; and if completed, the processing is terminated.
FIG. 11 is a flowchart showing a processing procedure of distribution section 511 of the embodiment. In step 1101, distribution section 511 of distribution management device 130 receives a distribution instruction including a distribution schedule, an electronic book, and information for goods of the book from content database device 120. In step 1102, section 511 stores in magnetic disk device 503 the distribution schedule, the electronic book, and the information for goods thus received.
In step 1103, section 511 distributes, by converting by protocol conversion section 510 a communication protocol between content database device 120 and vending device 140, the electronic book and the information for goods to each vending device 140 associated therewith according to the distribution schedule. In step 1104, section 511 makes a check, for each vending device for which the distribution processing is conducted according to the distribution schedule, to determine whether or not the distribution of the electronic book and the information for goods to the vending device has been completed. If the distribution to the vending device has not been completed, control returns to step 1103 to continue the processing. If the distribution has been completed, the processing is terminated. It may also be possible to use broadcast communication to a plurality of vending devices 140 via a communication satellite or the like. Namely, the electronic book and the information for goods are distributed at once to each vending device for which the distribution processing is conducted according to the distribution schedule.
FIG. 12 is a flowchart showing a processing procedure of processing section for receiving distributed content 610 of the embodiment. In step 1201, section 610 of vending device 140 receives the electronic book and the information for goods distributed from distribution management device 130 and then stores the electronic book and the information for goods in magnetic disk device 603. In step 1202, section 610 adds the received information for goods to the existing information for goods to thereby update data, which is used in retrieval processing when a customer selects an electronic book for the purchase thereof. In step 1203, section 610 determines an available capacity of magnetic disk device 603 to conduct disk management processing such as processing which deletes, according to the value of the available capacity, data which has not been recently used for the sales processing.
FIG. 13 is a flowchart showing a processing procedure of sales processing section 612 of the embodiment. In step 1301, selecting section 611 of vending device 140 displays on display 605 a graphical user interface (GUI) to conduct retrieval of an electronic book and then receives a retrieval condition inputted by a customer. When a retrieval condition is inputted by a customer, section 611 conducts in step 1302 retrieval through the information for goods in vending device 140 to read out an information item for goods of an electronic book which matches the received retrieval condition. In step 1303, section 611 displays on display 605 the information for goods of the electronic book obtained as a result of the retrieval and then receives an input of an electronic book selected by the customer.
In step 1304, section 611 makes a check to determine whether or not a particular electronic book has been selected in the displayed information for goods by the customer. If an electronic book has been selected, processing goes to step 1305. If the retrieval is again instructed, processing returns to step 1301 to receive an input of a retrieval condition.
In step 1305, sales processing section 612 checks to determine whether or not the electronic book selected by the customer has already been distributed. If the electronic book has already been distributed, processing goes to step 1307 to execute sales processing of the distributed electronic book. If the electronic book has not been distributed, processing goes to step 1306 in which section 612 transmits by distribution request section 613 the distribution request of the electronic book to distribution management device 130 to receive on-demand the distribution of the electronic book.
FIG. 14 is a flowchart showing a processing procedure of processing section for relaying request content 512 of the embodiment. In step 1401, section 512 receives a distribution request from vending device 140. In step 1402, section 512 makes a check to determine whether or not an electronic book requested by the distribution request has already been stored in magnetic disk device 503 of distribution management device 130. If the book has been stored in device 130, processing goes to step 1405; otherwise, processing goes to step 1403. In step 1403, section 512 sends the distribution request received from vending device 140 to content database device 120 while converting by protocol conversion section 510 a communication protocol between content database device 120 and vending device 140.
FIG. 15 is a flowchart showing a processing procedure of requested content distribution section 412 of the embodiment. In step 1501, section 412 of content database device 120 receives the distribution request sent from vending device 140 and relayed by distribution management device 130. In step 1502, section 412 makes retrieval for the electronic book requested by the distribution request received. In step 1503, section 412 reads out the electronic book as a result of the retrieval. In step 1504, section 412 sends the obtained electronic book to distribution management device 130 and instructs device 130 to distribute the book.
