Description

{Distributing, controlling and generating digitalized learning contents}

The field of the present invention is a field related to the distribution method and revenue generation of content generated through the production tool and production tool of digital learning content.

Currently, the market size of the digital learning market is growing, the possibilities are endless, and the fact that ON-line education reduces the burden of expensive off-line education in the situation where private education market reaches 30 trillion won is true.

However, the growth of ON Line education is hampered by the following problems of other existing learning programs.

The contents usage, distribution, and revenue generation of existing digital learning contents related programs are as follows.

First, as shown in FIG. 3, a program provider provides or provides a digital learning content-related program for free, and a user uses the content generated through the program for his or her own or without any restrictions for a fee or free of charge. R program is a program that can only read content, and R / W program can create and use content)

From the program provider's point of view, when the program provider provides the program free of charge, the program becomes widespread and easy to generalize, but there is a problem such as generalization of the program due to the burden on the user when the provider's willingness to develop is lowered and paid for.

Also, from the program user's point of view, if you purchase a program for your own use, you are reluctant to purchase it because of the burden of purchasing it. When using free programs, there are problems such as poor quality

In terms of user's use and distribution of contents, there is no problem in producing contents for their own use or providing them for free, but there are problems such as managing distribution of contents when paying them to others.

Next, as shown in FIG. 4, a program provider purchases a right to distribute a program capable of generating and reading a program capable of generating content and a server program related thereto (a server program may not be purchased depending on the characteristics of the content). Make money by giving money or free distribution

Content developers develop content, upload it to servers, and make money by paying royalties to those who have other read-only programs or by paying royalties to server administrators.

However, the biggest problem with this method is that there is a division between the author of the content and the side of using the content, so that a content user with a read-only program cannot generate the content for himself or a limited range of people, so there is a limit to the content creation and purchase. Even if you try to do this, the cost of purchasing the program will be burdensome and you will be reluctant to purchase.

In addition, both of the above methods do not have a group ID, table of contents method, co-production method, group management method, easy paid content provision method, step-by-step payment of copyright fees, etc. It has low efficiency.

The present invention has been made to solve the problems of the existing method, the development of the contents use program provider by the generalization of the digital learning content use program and the payment of the content distribution stage, the development of the program quality improvement and the cost of the program user It eliminates the burden and eliminates the limitation of the generation of digital learning contents by not separating the read-only program and the content generating program, and when the content creator wants to provide the contents generated by the user for a fee, it is easy to pay without any burden. By opening up, it will inspire the content creator to develop high quality content.

It aims to prevent the act of providing content to others by modifying the content, which is a problem that can be caused by the function of generating content and reading function in the production program.

By introducing group ID, table of contents method, co-production method, group management method, phased copyright payment, and easy monetization, it eliminates the inefficiency of existing content creation and management and revenue management method in content creation and management and revenue management method. The purpose.

Figure 4. Existing digital learning content program and content distribution method 2

The following works in detail: (See Figure 2.)

First, look at the client (local computer) running the content authoring program (1).

The user interface unit 2 is composed of a monitor, a keyboard, a mouse and the like.

The program driver 3 is a unit for driving a learning program.

The data storage unit 4 is a place for storing learning content, and is composed of a fixed device such as a hard drive and a portable storage device such as a floppy or a CD.

The program control unit 5 is a program that controls the function of the learning program. The program control unit 5 is paid, free, read only, writeable, or payable using information stored in the learning content (additional information) or information stored in the server (content rights information DB). The program control is used to control the learning program. (The program controller is not separated from the program driver but divided to help understand the principle of controlling the use of the content.)

The network connection unit 6 is a part for connecting to an external network and is composed of software such as a connection program (Socket program) of an operating system that enables connection, and hardware such as Lan Card and Modem.

Network (7) is composed of Lan, Wan, and Internet.

The storage medium (8) is a removable storage medium for storing and moving data located outside the computer, and is configured as a removable storage medium such as floppy or CD.

The server 9 is composed of a program for providing services through the operating system and the network, and has a DB for data services.

The content storage DB 10 is a DB for storing learning content produced by a client (learning software authoring program), and has information such as file type (table of contents, contents), content registration number, file name, and upload date.

The content information DB 11 is a DB containing information on content, content registration number, content name, content classification, content introduction, day amount, monthly amount, permanent amount, group ID, subject author ID, group use, DB that contains information about free number of people

The content authority DB 12 is a DB that stores usage rights for each member of each content, and is a DB having a group ID, a member ID, a revenue dividend rate, a content registration number, a content name, a use right, a use start date, and the like.

Member information DB (13) is a DB that contains the information of the registered members, DB that has the group ID, member ID, PassWord, address, telephone, affiliated organizations, repayments, etc. of members

The use history DB (14) is a DB that stores the learning results of members who use the content, and has a group ID, a member ID, a content registration number, a content name, a content use date, a progress, an achievement, and a noon answer file for each problem. DB.

Now look at the functional configuration of the present invention.

First, Figure 1 shows the overall operation, the program provider is a program that can create and use content to the user (programs that can run on a general OS, or programs that can run as a plug-in on a web browser like ActiveX, Java, etc.) (1 to 1 refer to No. 1 of FIG. 1), and the server managing the generated content is sold or managed (FIG. 1 to 1 and 1 to 1-1). 1 ~ 1-2) Generate profit.

Users sign up for membership through the program or web browser (Figs. 1 and 2, 1 and 2-1) and log in to use the program (Figs. 1 and 3, 1 and 3-1).

At this time, when logging in, the group ID is used. The group ID is as follows.

First of all, in terms of group ID, this means that a school or academy using learning contents (here, academy, school, etc.) is in high demand for learning contents and has a server that can use contents with their own content creation or use program. For those who want to operate but do not have the ability to produce programs or operate the server, the visual design is changed from the group to the desired format in the program related to learning contents already produced by the group. It operates as follows, but puts a group ID indicating the group using the program in the program or group's website so that the user connects with the user ID and password only when logging in, but the program or web browser enters the group ID, user ID, and password. Send to server Since the server classifies users by group ID and user ID, and provides the corresponding services such as group IDs in the content information DB (Fig. 2 ~ 11) when searching for content, users log in with their own ID only. By separating users into groups in one server, groups have the same effect as running their own programs and their own servers.

Also, if you put the group ID in the table of contents file and the additional information on the content file, and read the group ID from the program when using it in the program, the authority information of the server's content authority DB (Fig. In this case, the usage information on the additional information of the content is read and used according to the usage method. However, when the group ID on the program and the group ID on the content are different, the use of the content is blocked.

Up to this point, both the producing and using content (the producing program, the using program, or the same program) go through the same process, but will be different from this point on.

First, from the side of producing content (Fig. 1 to User 1), the content is produced using the program after the above process.

When the content is produced, a table of contents file and a content file are produced by using the table of contents method introduced in the present invention. The table of contents file plays the same role as the table of contents of the book and is configured in the same way as the table of contents of the book. have.

When you open a table of contents file by selecting a table of contents file in the program, the table of contents is displayed. Each title of the table of contents is linked to several contents files. Depending on the authority of the contents file or the authority registered in the server, Allows you to edit or learn. If you do not have edit rights to the content, you can not edit by preventing the use of the edit mode that allows you to use the various editing-related functions.

The table of contents file is divided into table of contents headings and file names, which are hidden attributes of each table of contents headings. When creating and saving a table of contents file, the group ID, the subject author ID, the date of the table of contents production, and the description of the contents are saved together. When the table of contents file is edited, the group ID and the subject author ID must be matched for editing.

At this time, when the contents file is being edited and the contents file is created, the group ID and the producer ID in the additional information of the contents file are checked and the ID can be edited when the contents match.

If the group ID in the additional information of the file, the creator ID and the ID of the logged-in user are different, or if a new production is made, the server has the authority to edit the content by querying the content authority DB (Fig. 2 ~ 12) (secondary producer). The program control unit operates in the edit mode to allow editing and creation of new contents.

This is a joint authoring method, which defines the scope of each author, and then divides it. The main producer has overall authority over editing and contents of the table of contents, and the sub-producer divides the contents of the contents and generates revenue. When the revenue is distributed in the recharge field of the member information DB, the revenue dividend ratio of the content authority DB of the server is received.

In addition, new contents of editing and contents are classified by table title, so the actual contents file is divided by table title, so only the necessary parts are uploaded and downloaded to reduce the load on the server.

If the contents and file name correspond to the hidden file name specified in the title shown in the contents window, the contents and the contents file are linked. If you specify a file name in advance and start editing in the edit window, a new file name, which is predefined in the title of the table of contents, is created as a content file.

The content file contains the actual content of the study, which precedes the question and answer format (document, sound, video, web page format, and the question and answer format that is supported by the program itself). It is written in the form of contents composition).

The content file is produced in the form of document and sound recording, video recording, web page creation and question and answer format in advance in the learning program or the program supporting each format. Will be arranged according to.

After that, the contents configuration file is merged according to the procedure of saving and saved as a file in the location designated by the user.

When the content file is created and saved, additional information such as producer information (group ID, producer ID), usage method (paid or free), usage rights (read only, write and modify available), table of contents file name, production date, etc. After inputting the value and input from the user, after encrypting it with the contents file (Fig. 1 ~ 4), it is stored.

Now, when we look at the editing rights, the editing rights are the only authors who have editing rights when producing content by themselves, but they are divided into main producers and sub-producers when many people produce them. In order to ease the burden, the main producer first finds a sub-producer who will produce the content, and then in consultation with the sub-producer, decides on the share of revenue and part of each part, and uploads the table of contents to the server.

Then, on the web page or program, the ID and revenue of the main producers and the sub producers are registered (the percentage of distribution of profits between producers).

At this time, the server creates the permission record of the producers in the content rights DB. The usage rights field is changed to the producer or the sub-producer, and the distribution rate of the subject author registered in the distribution rate is recorded.

The supplementary producers download the table of contents posted on the server, write their respective sections, and upload them to the server. After that, when the revenue for the content is generated, the server management company distributes the revenue to each author as a distribution ratio for the previously determined revenue.

After that, in order to provide the content to others, the publishing process is selected, and the program selects paid or free (Figures 1-5).

First of all, when paying (Fig. 1 ~ 6), the creator selects the paid offer after accessing the server in the program, and inputs the amount according to the content name, content classification, content introduction, and usage period (day, month, and permanent use). If registration is selected, the above information, group ID and main producer ID in the program are added to add or modify data in the DB related to the server's content, and the server receives a content registration number, which is a unique number for uniquely distinguishing the content from the server. do.

Then, the program saves the content number in the table of contents file and the content file, changes the place where the free information of the content file is judged to be free, and saves and uploads the registered content to the server specified in the program (Fig. 1 to 7). Or, go through the steps of saving on the Internet web page, storage device (Fig. 1-9) is published for a fee.

If you are uploading to the designated server or saving to the storage device, you can save or upload to the designated server by selecting Copy or Upload to the designated server from the table of contents in the table of contents. Will be done.

If you choose free (Fig. 1 ~ 8), select the content to publish, change the place where the free information of the content file is judged free, save it, and save it and provide it to others through the storage device or network (Fig. 1 ~ 9). Done.

In terms of using the content (Fig. 1 to User 2) is as follows.

First, the user downloads the program (Figs. 1 to 1-1). And if you are not registered as a member (Fig. 1-2-2). At this time, the subscription information is automatically included in the group ID in the program or web page, and stored in the member information DB (Fig. 2 ~ 13) of the server.

Then, the user logs in to the program to use the program. At this time, the ID, password, and group ID entered by the user are compared with the data in the member information DB (Figs. 2 to 13).

The user then retrieves the learning content information, which can be retrieved as a file from a removable or fixed storage device, or from the server's content information DB (Figures 2-11) on a web page or on a program. Done.

When searching on a web page or a program, the learning content information can be divided into two types. First, it can be divided into the content information used for the existing one and the content information to be searched for new use.

The existing content information is provided in the content rights DB of the server (FIGS. 2-12), and the information to be searched for newly used is provided in the content information DB (FIGS. 2-11). At this time, the information includes the learning content name, classification, brief content introduction, author name, royalties, and the like.

When the user attempts to use the selected content on a file or on the web or on a program (FIGS. 1 to 10, 11, 12), the program is divided into a program control unit (the program driving unit and the control unit of FIG. The program driver learns and handles the interface with the user, and the controller controls the use of the content.) If the selected content is paid content, the additional information on the file is selected. If it is checked on the web or program, it is checked in the content information DB (FIGS. 2-11).

If the content is not paid content but free content (Figures 1-12), the program control section allows the learner to use the learning content.

In the case of paid content (Figs. 1 to 10), the learner has the authority to use the content or checks in the use authority field of the content authority DB (Fig. 2 to 12) of the server.

If the logged-in ID and the copyright holder of the content are the same (FIGS. 1-11), all operations (upload download, loss, edit, etc.) can be performed regardless of the information stored in the content.

If the user does not have permission to use the content, the user is directed to a payment web page to make a payment. At this time, the payment method uses an external payment company.

When the user has made a payment, the payment information is transferred from the payment agency to register the use right for the user's content in the content rights DB (FIGS. 2-12).

When the user pays for the content and the authority to the content is registered, the content provider divides the copyright fee for the content and the company providing the service differentially according to the total amount of the payment. With reference to the amount of use of each period in (Fig. 2 ~ 11), the amount of payment is made from the beginning by adding the accumulated amount of usage rights (cumulative number of usage rights * amount of usage = cumulative amount of usage rights) to the content rights DB. Until the loss, the producers have the same amount for the payment, and the more the payment is, the more money is added to the company at the rate specified by the server program.

For example:

Content Provider Company

Cumulative amount 0 ~ 100,000 won 100% 0%

Cumulative Amount 110,000 ~ 200,000 Won 90% 10%

Cumulative Amount 210,000 ~ 300,000 KRW 80% 20%

Cumulative amount over 300,000 won 70% 30%

The reason for using the above-mentioned differential payment method is to improve the motivation for producing the content by paying more money to the provider when the content is initially uploaded, and even if the amount increases, the content provider gets more money from the company. This is to raise a lot of money to arouse the motivation of the content providers and improve the profits of the company.

In the distribution with the companies and the distribution among the producers, the newly paid amount is first deducted from the company-side revenue specified in the server program, and the rest is distributed according to the distribution ratio between the producers. Added to.

If the user has permission to use the content, the program driver (Figures 2 to 3) checks whether there is a content table file or content file in a specific folder on the user's computer, and the content (content table file, content file) If it is on the computer to use the content, if not necessary to search the content registration number, file name in the content storage DB (Fig. 2 ~ 10) of the server to download and use.

When the user finishes using the content, the program asks if the program will save the learning results, and if not, exits the program.

In case of saving, check whether the content currently being used is paid content or free content through the program control unit (FIGS. 2-5). If the content is free, the group ID, user ID, content name, date of use and progress on the local computer. Save and exit information such as achievement, noon and answer file for each problem, and ask if you want to save in the usage history DB of the server (Fig. 2 to 14) in the case of paid content or the computer you are using.

If you select Save to computer, information such as group ID, user ID content name, date of use of content, progress, achievement, noon and answer file for each question, etc. will be saved.

If you choose to save to the server, information such as member ID, content name, content usage date, progress, achievement, noon and answer for each problem in the usage history DB (Figs. 2 to 14) and ends.

In addition, the stored learning result data is displayed to learners as progress management, achievement, etc. in the program, or used as program control such as review by extracting wrong problems, and if the content learner saves the learning result data on the server and manages author progress In the case of permission (the permission field of the content authority DB (Figs. 2-12) is registered as a group), the author can search the learner's usage history DB (Figs. 2-14).

In terms of managing the content users are as follows.

There is a group registration method, which is used for schools or academies, and the author can register a desired user as a group to manage the progress of the user's own content or pay the content usage fee.

Looking at how group registration works

First, the content producer records the group use when registering the content in the group use field of the content information DB (FIGS. 2-11). Then, when the user wants to register with the group, the user selects the content and then applies for the use of the content group. At this time, the information about the user's use of the content is stored in the authority DB (FIGS. 2-12), and is recorded as a group application in the usage authority field of the content authority DB.

Then, the author can search the content authority DB to view the ID of the user who applied for the group among the user IDs corresponding to his or her content registration number.

The author selects the user ID that he / she wants to register as a group among the user IDs, and selects a payment method for payment. This means that the user pays the content fee for the payment method in the application of the permission field of the permission DB (Figs. 2-12). The author pays the user's content fee (primarily the structure in which the user receives the fee from the user after payment), and the content is free to use. At this time, if the user selects free, the user can use the content for free by changing the group's permission field in the content permission DB, and at this time, the company designates the number of people who can author the group for free. Compared to (Figures 2-11), if the number is exceeded, the author is warned to re-adjust the number of free groups, and if not, the permission field of the content rights DB (Figures 2-12) is modified for free.

If user payment is selected, the permission field of the content permission DB is changed to user payment. If the user pays while waiting for payment, the permission field of the content permission DB is changed to group pay.

When the author payment is selected, the authority field of the content rights DB is changed to the author payment, the total number of users selected by the author payment is multiplied by the payment amount, and then the author is waited for the payment. When the author makes a payment, the permission field of the permission DB is changed to a group fee.

In the case of a group, the author's content user management method shows that the author selects a user whose authority field of the content authority DB (FIGS. With this you can reinforce the progression or the lack of learning by the user when making the next learning content or advise the user.

In the method of withdrawing a group, the author side removes the user from the group and the user leaves the group. First, the method of removing the user from the author side is as follows.

Authors can search for users whose content rights are group free or group paid in their content rights DB.

If the user selects the user who wants to withdraw from the group in the search result and selects withdrawal, if the authority is paid for the group in the content rights DB, the user is allowed to withdraw the fee by changing the permission to paid and allowing the user to continue using the content. The content cannot be used by removing the content right from the permission DB.

When the user side shows how to withdraw from the group, the user can look up the contents he is using in the content authority DB.

If you choose to leave a group for content that is group-paid or group-free, there will be a notice that the content is not available because the content is removed if the group is free, and the user's permission to use the content is removed. Done.

If the group authority is paid for the group, when the user applies for group withdrawal, the user withdraws from the group and the content is still available, and if the user agrees, the authority is changed from the group paid to the paid.

In the past, general digital learning contents users had difficulty in producing the contents of learning contents they needed, production was limited to some creators, and the contents produced by others did not match their own learning methods, and the learning effect was low. Although it was difficult for the general user to access, the general learning content users can easily produce digital learning contents for themselves by various methods provided by the present invention for their own use, and thus bring about an improvement in the learning level. The contents produced for writing can be provided to others free of charge, which means that the individual's competitiveness is improved.

In addition, in the case of paid content, various content creations will allow competition among creators to provide faster content modification and higher quality content at a lower price than previous online learning or books.

Looking at the effect of the present invention in detail

First, the programs that can use the contents are distributed free of charge. However, due to the paying through the control of the use of the contents, the diversification of contents and higher quality contents are available, and the program makers are profitable.

Second, by using the table of contents method, it is possible to create and use content more easily.

Third, by using group ID, it is possible to improve profitability by securing customers who are not capable of program production and server operation.

Fourth, by using a co-production method of content, even a large amount of content can be easily produced by many people.

Fifth, by using the group management method, feedback can be provided to the author, so that the progress management and the content that the user can understand more easily can be made.

Sixth, by paying a gradual royalty fee, content makers will be more willing to produce and profitability can be expected from management companies.

On the other hand, the present invention is not limited to the above-described embodiment, various modifications are possible by those skilled in the art within the spirit and scope of the present invention described in the claims to be described later.
