Description

Data delivery system and delivery method Technical field

The present invention relates to a data distribution system and a data distribution method for distributing information provided from an information supplier in response to a request from an information user. Background art

In recent years, with the rapid spread of networks, ordinary users can obtain data on various copyrighted works, such as image data, audio data, and text data, via the network. ing. In addition, the author of a work can publish his or her work easily without having to go through a publisher or broadcast media, for example, by publishing his or her work on the network. In this way, by distributing the copyrighted work using the network as a medium, the user can obtain the desired copyrighted work without the need for geographical and temporal handicap. The work can be announced without the need for funding.

When a user finds a desired copyrighted work on the network and tries to obtain it, he or she must perform a procedure for payment of the fee in advance through so-called e-commerce, and after this procedure is completed, download the data of the copyrighted work. And import that data into its own terminal.

Also, when an author publishes his or her work, he or she will post the finding of the work on his or her Web page. If a user who browses this Web page requests distribution, the content data of the copyrighted work is distributed to the user on the condition that the prescribed procedure for the fee has been completed.

By the way, according to the conventional data distribution method using the network described above, a general user has to download all the data of the copyrighted work provided by the creator as it is. Has not been able to distribute data in the form that it requires. For example, when distributing a video of a certain copyrighted work, Even if there is enough data for a minute or if the image does not need to be of high quality, all of the data of this copyrighted work will be delivered to the user at the predetermined quality. Accordingly, the user is forced to pay an excessive fee. In addition, for the author of a copyrighted work, if the copyrighted work is made public on the network, it is subject to plagiarism by a third party, and thus copyright infringement cannot be effectively prevented.

Reference numeral 300 denotes a data delivery system installed on the data delivery business side. Reference numeral 400 denotes a server installed on the network service business side, and reference numeral 500 denotes a terminal installed on a general user side.

As shown in the figure, the server 200 installed at the data supply source, the data distribution system 300 installed at the data distribution business, and the network service business side The server 400 is connected via the network 100. The terminal 500 on the user side is connected to the server 400 via the network 600. Terminal 5

The data transmitted from 00 is temporarily stored in the server 400, or transmitted through the server 400 to the network. In Figure 1, the server that supplies the data, 20

0 and the user's terminal 500 seem to be directly connected via the network, but the content data provided by the supplier is not

It is distributed to the user via 0. Therefore, if attention is paid to the content data distribution route, a data distribution business will be interposed between the data supplier and the user.

FIG. 2 shows a configuration example of the data distribution system 300.

In the figure, reference numeral 310 denotes a data base, which is composed of a content database 311 and attribute data 312 and 313. The content database 3 1 1 stores the content data of various copyrighted works to be distributed. It stores image data such as moving images and still images, audio data such as music, and character data such as novels. When registering content data in the content database 3 1 1, copyright related processing must be completed in advance. Specifically, the content data of the supplier is attached with data such as the rate distribution ratio according to the contract concluded between the author of the work (content data supplier) and the data distribution business. It is registered in the application data 311 and the accompanying data is registered as attribute data 312.

Attribute data 3 1 2 is data that is commonly applied to each user to search for content data (hereinafter referred to as “common attribute data”), and attribute data 3 1 3 is applied to each user. (Hereinafter referred to as “user-specific attribute data”). As the attribute data, for example, information representing subjective emotions such as “fun”, “happy”, and “scary” (hereinafter referred to as “emotion tags”) is included in the content database 311 Is defined in association with the code that specifies The contents of the common attribute data 3 1 and 2 are determined and determined according to the logic of the supplier of the data overnight, and are provisional (provisional). As will be described later, the contents of the attribute data by user 3 13 are obtained by reflecting the judgment of the user ^ に in the common attribute data 3 12.

Reference numeral 320 denotes a distribution processing system that distributes content data of a copyrighted work in response to a request from a user. The distribution processing system 320 is composed of a distribution request reception processing unit 321, a data retrieval processing unit 322, a data processing processing unit 323, a rights protection processing unit 3224, and a data distribution processing unit. Consists of 3 2 5 Among them, the distribution request reception processing section 321, the data search processing section 322, the data processing processing section 323, and the right protection processing section 3224 constitute a distribution data generating system 32OA.

Here, the distribution request reception processing section 3221 is for receiving a distribution request transmitted from the terminal 500 installed on the user side. The data search processing unit 3 2 2 searches the content database 3 1 1 1 with reference to the attribute data 3 2 1 and 3 1 3 described above, and obtains content data matching the user's request. Things. The data processing section 322 is for processing the content data acquired by the above-described data search processing section 322 in response to a user request. When distributing the content data to the user, the rights protection processing unit 3 2 4 This is to apply the processing required to protect the crop to the content data. The data distribution processing section 325 is for distributing the content processed by the data processing section 323 to the user.

Next, reference numeral 330 denotes a content registration processing unit, reference numeral 340 denotes an attribute data correction processing unit, reference numeral 350 denotes a content generation unit, reference numeral 360 denotes a right management processing unit, and reference numeral 370 denotes a charging process. Reference numeral 380 denotes a system control unit.

Here, the content registration processing unit 330 receives the content data from the content data supply source, encodes the content data, and registers the content data in the content data base 311. It has a function to acquire attribute data of content data.

The attribute data overnight correction processing unit 340 analyzes the usage status of the content data stored in the database 310 and reflects the analysis result to reflect the attribute data of the content data overnight by user or This is corrected for each user group. The content generator 350 generates a new content database by changing the combination of components of the content database based on the usage status of the content data stored in the database 310. It generates new content data that meets the usage conditions of individual users.

The rights management processing unit 360 evaluates the information value of each component of the content data based on the ratio of each component to the newly generated content data and the number of uses, and based on the result of the evaluation, A processing function (first processing function) for executing the processing required to manage the copyright and neighboring rights of each component of the data, and the content data when adding new content data separately A processing function for predicting the future value of the content and executing a process required for managing the copyright and the neighboring right of each component of the content data based on the result of the evaluation and the prediction (second Processing function).

The billing processing unit 370 determines a fee to be borne by the user and the supplier in order to distribute the content data according to a predetermined rule according to the usage status of the content data, and It charges the supplier. Here, as the above-mentioned predetermined norm, for example, present value of information, strong / weak vector information of present value of information There are rules for determining the future value of new data based on the evaluation of similar data and similar data. Further, the charging processing unit 370 executes a payment fee payment process for the right holder of the content data based on the charging processing result.

Hereinafter, the operation of this embodiment will be described.

First, the process for distributing the content of a copyrighted work in response to a user request will be described along the flow shown in FIG. Various controls related to the following series of processes are performed by the system control unit 380 shown in FIG.

Step S10: Upon receiving a distribution request from a user, the distribution request reception processing section 321 of the data distribution system 300 urges the user to select a data request method.

There are two ways to request this data: a method in which the user requests data explicitly or implicitly, and a method using the emotion tag described above.

In the method of explicitly requesting data, a code is assigned to each content data in a one-to-one correspondence, and a user specifies this code to specify desired content data. Also, with implicit requests for data, taking no action by the user is simulated as a manifestation of the willingness to request data. For example, if program data related to a calculation problem is distributed to a user and an incorrect answer occurs during the process in which the user solves the calculation problem according to this program, if the user does not take any action, the correct We judge that the information is implicitly requested, and we will send an official message to this user.

In this example, even if there is no direct request from the user, since there has been no action, the user has been worried about the fact that there was no action. Is determined to be required. In this way, in the method of implicitly requesting data, it is determined from the flow of a series of procedures up to that point whether the user needs the data and whether the user has issued the request. If it is determined that data distribution is requested, that is, if no action is taken, the necessary data is distributed to the user.

The method using emotion tags is based on emotion tags specified by the user. Identify Tendde overnight.

It should be noted that the data distribution request may be made by using both the above-mentioned explicit / implicit request method and the request method using the emotion tag.

In addition, the user sends information on payment of the fee (payment information) and information on the quality of the data (quality information) along with the data distribution request. For example, in the case of an image of a movie or the like, the desired fee is transmitted as payment information, and information on the data section (for example, the first 30 minutes of the video section) and the data compression method are transmitted as quality information. It should be noted that only the payment information may be transmitted, or only the quality information may be transmitted. If only the payment information is sent, the quality of the image is determined according to the fee presented by this payment information. When only the quality information is transmitted, data that satisfies the image quality indicated by the quality information is delivered.

Here, the description returns to the flow of FIG.

Step S11: Subsequently, the distribution request reception processing section 321 analyzes the content of the user's request, acquires the code or emotion tag of the content data requested by the user, and determines the quality. I do. Specifically, when the user makes an explicit request, a code for the content data related to the request is obtained. When the user makes an implicit request, the content data code corresponding to the result of the analysis of the request is obtained. Further, when the user uses the emotion tag, the user obtains the code of the content data corresponding to the attribute tag by referring to the attribute data 312.

Quality decisions are made based on payment and quality information. For example, if the fee is low, remove the bit or screen, and change the compression method as needed. If the fee is high, the content data is not processed and is left as it is.

Step S 1 2: Subsequently, the data search processing section 3 2 2 searches the content data base 3 1 1 based on the content data code acquired by the distribution request reception processing section 3 2 1 described above. I do.

Step S13: Subsequently, the data search processing section 322 determines whether or not the content database 311 has a corresponding content database. Step S14: Here, if there is no corresponding content data (step S13: NO), this is output as a report and the user is notified.

Step S15: Also, if there is the corresponding content data (step S13: YES), the data processing part 3 23, based on the analysis result in the above step S11, The quality of the content data retrieved in step S12 is processed. Specifically, in accordance with the above-mentioned payment information and quality information, the content data obtained by the search is subjected to processing such as "bit exclusion", "screen exclusion", "change of conversion type", etc. Process according to the requirements of the manufacturer. At this time, if necessary, a process of selecting and combining a plurality of corresponding content data is also performed.

Step S16: Subsequently, the rights protection processing section 3 2 4 performs electronic processing necessary for the protection and management of rights such as copyrights and adjacent rights to the content that has been processed in quality. Specifically, protection (guide) processing to prevent unauthorized duplication is performed.

Step S17: Subsequently, the data distribution processing units 3 and 25 distribute the content data subjected to the electronic processing in step S16 to the user.

As described above, a series of data distribution processing is performed.

Next, the operation of the content registration processing section 330 (content data registration processing) will be described along the flow shown in FIG.

As described below, the copyright holder of the copyrighted work (the source of the content data) sends the content from the server 200 to the data distribution system 311 of the data distribution system 300, as described below. Register target content data. This registration-related processing is performed by the content registration processing unit 330, as described below.

Step S20: In registering the content data, the content registration processing section 330 requests the copyright holder of the copyrighted work, that is, the data supplier, to set permission conditions, which are conditions for permitting distribution. I do. Specifically, we will ask for answers for each item such as data usage, media, compression / encoding method, expiration date, copy conditions, transmission route, and whether or not to create a database. The data distribution business can only dispose of the rights holder's content data within the scope of this license condition.

Step S211: After setting the permission conditions described above, the content registration processing section 330 The content server receives the content data from the data source server 200 and encodes it. Further, the content registration processing section 330 receives, from the server 200, an emotion tag indicating the content of the content in addition to the content data.

Step S22: Subsequently, the content registration processing section 330 registers the encoded content data in the content database 311 and stores the emotion tag of the content data in the attribute data 311. Keep as 2. At this time, the content registration processing section 330 assigns an identification code to the content data, and associates the code with the emotion code as attribute data 312.

As described above, the content data is accumulated as needed from the data source as a data distribution system 300 data.

Next, the correction process of the common attribute data 312 will be described along the flow shown in FIG. 5A.

In the above-described overnight distribution process (steps S10 to S17), the database is searched using the attribute data 312 determined by the logic of the data supply source. The emotion tag specified in 3 1 2 may not always match the user's emotion. Therefore, as described below, the common attribute data is appropriately modified to reflect the judgment of the user who received the data distribution.

Step S30: The attribute data correction processing section 340 evaluates the satisfaction of the user based on the reaction of the user. As an example, calculate the ratio of the time and data amount that the user actually watched to the time and data amount when the user watched to the end.For example, use when the ratio exceeds 70%. The satisfaction of the participants was evaluated (indirect evaluation method). As another example, we collect information about user satisfaction expressed or implied (direct evaluation method).

Step S31: Next, based on the evaluation result of the degree of satisfaction, the subjective emotions of the user appreciating the delivered work and the common attribute data 3 attached to the content data of this work. Evaluate the degree of matching with the content represented by the emotion tag of 1 and 2. Specifically, for each user, information indicating the degree of matching (hereinafter referred to as “matching information”) is acquired and stored. Then, statistical processing is performed on the accumulated matching information of a plurality of users, and the contents of the common attribute data 3 1 2 determined unilaterally by the logic of the data supply source, and Understand the discrepancies between the emotions actually held by the user.

Step S32: Subsequently, based on the evaluation result of the matching degree in the above step S31, it is determined whether or not the common attribute data 312 needs to be modified. In other words, if the emotion tag of the common attribute data 3 12 determined by the logic of the data supplier differs from the emotion held by the user of the content data to which the attribute data is added, the common attribute data 3 1 2 Is not valid. Therefore, if the content of the common attribute data 3 1 2 determined by the logic of the data supplier greatly differs from the emotion actually felt by the user, it is determined that the common attribute data 3 1 2 needs to be modified. I do.

Step S33: If it is determined that it is necessary to correct the common attribute data (step S32: YES), the subjective emotion of the user matches the content of the common attribute data 312 The emotion tag of the common attribute data 3 1 2 is changed so that the common attribute data 3 1 2 is modified. If it is determined that there is no need for modification, the processing in step S33 is omitted, and the common attribute data is not modified.

As for the criterion for determining whether or not it needs to be modified, those expressing the same emotion are grouped in advance by applying a statistical method to multiple emotion tags. If they belong to the same group, it is determined that there is no need for correction. If they belong to different groups, it is determined that correction is necessary. For example, the emotion tags are classified into four groups, "happy", "angry", "sad", and "easy". For example, the emotion tag related to "scary" belongs to the group Group has the emotion tag related to "fun", the group "sad" has the emotion tag related to "sad", and the group "easy" has the emotion tag related to "fun". .

Here, for example, if the emotion tag of the common attribute data indicates “scary” and the emotion actually held by the user is “sad,” these belong to different groups. It is determined that it is necessary to correct the emotion attribute of the common attribute day. For example, if the emotion tag of the common attribute data represents “fun” and the emotion actually held by the user is “pleasure” belonging to the same group, the emotion tag of the common attribute data is Determine that there is no need to modify.

As described above, the emotion tag of the common attribute data 3 1 2 matches the emotion of the user. Will be modified to

Next, the creation of attribute data by user 3 13 will be described.

The above-mentioned common attribute data is applied to unspecified users, and in that sense, is determined by the greatest common divisor. However, the feelings of individuals vary widely, and although the frequency is low, it may not be possible to deal with common attribute data. Therefore, for users who access frequently, dedicated attribute data is prepared as user-specific attribute data 3 13.

Hereinafter, the creation process of the user-specific attribute data 3 13 will be described along the flow shown in FIG. 5B.

Step S40: The attribute data correction processing section 340 evaluates the user's satisfaction in the same manner as the processing in step S30 described above.

Step S41: Subsequently, as in step S31 described above, based on the evaluation result of the satisfaction level, the subjective feelings that the user had while appreciating the distributed work and the Evaluate the degree of matching with the content represented by the emotion tag of the common attribute data 3 1 2 attached to the content data. However, in this case, accumulative information is accumulated for each user and statistical processing is performed to grasp the discrepancy between the content of the common attribute data 312 and the emotion actually held by the user .

Step S 4 2: Next, modify some of the emotion tags in the common attribute data to match the user's subjective emotions, and change this to the user-specific attribute data. Register as 3.

The above-described series of processing in steps S40 to S42 is executed every time a user accesses, and the contents of the corresponding user-specific attribute data 313 are updated.

As described above, attribute data optimal for each user can be obtained, and the hit rate when searching the database is improved.

The system control unit 380 outputs the matching information obtained in steps S31 and S41 to the outside as necessary. By using this matching information, for example, a broadcasting station as a data source, it is possible to grasp the audience rating and obtain hints for program production.

Next, the operation of the content generation unit 350 will be described. The content generation unit 350 creates new content data based on the matching information obtained by the attribute data correction processing unit 340 described above. For example, if the content data is composed of music data and image data, and the image data is composed by combining character data and background data, these components are selected and edited again, and a new Content data. In other words, based on the matching information reflecting the user's emotions, necessary components are extracted from the initial content data created by the data supply source and synthesized as new content data. As a result, it is possible to distribute content data more suited to the user's emotions.

Next, the operation of the rights management processing section 360 will be described.

This rights management processing unit 360 is used to reflect the above-mentioned matching information to reflect the content data of a new work created by the data supplier, or to create new content generated by the content generation unit 350 described above. Performs copyright and adjacent rights processing on the data.

Hereinafter, the operation of the rights management processing section 360 will be described by taking as an example a rights process for determining the amount of money to be distributed to each copyright holder in the content data.

First, the ratio of each component (music, background, character of a person, etc.) of the newly generated content data to the entire content data is calculated. This ratio will be adjusted to reflect the actual results of use by users (hereinafter referred to as “use results”). That is, the ratio of the physical data is corrected according to the actual popularity of each component, and this is set as the popular data. For example, if many users are very interested in the character of a particular person, this character has a great value in terms of merchandise, and according to this value, the above ratio can be increased to a large value. Fix it.

Next, a usage record volume representing the usage volume of each component of the content data is accumulated. It stores the number of times each component of the content data that the user wishes to distribute is used.

Next, various rights processing is executed based on the above-mentioned popular data and the usage record poly-day. Specifically, the ratio represented by the popular data and the usage For example, it is multiplied by the number of times of use expressed in one night. The result of this multiplication is used as evaluation data for each component of the content data, and is used to determine the amount to be distributed to the creator of the work.

As described above, various rights processing is performed.

Next, the operation of the charging section 370 will be described.

The charging processing section 370 charges a user fee required for using this data distribution system to a person who uses this system.

First, the amount to be paid by the content data user (consumer) and the amount to be paid by the content data supplier are determined according to a predetermined standard. Here, this amount is determined based on the usage status of the content data. For example, for content data that is infrequently used, the provider of the content data bears the burden and urges the use of the data. In addition, if the content is frequently used, it will be borne by the user. The more popular the content data, the higher the user pays.

Next, regarding the determination of the above-mentioned amount, based on the above-mentioned matching information and the usage record volume data, an ROI for new content is generated and reflected in the distribution fee of this content. For example, when selling a young copyrighted work, the funds required for promotion flow to the market. Conversely, if this work is sold, profits will be returned from the market side to the promotion side.

Finally, the system control unit 380 issues an instruction for settlement (transfer, etc.) based on the rights relationship processed by the rights processing unit 360 described above and the amount determined by the charging processing unit 370. Sends the electronic information to the data user and the data supplier, and confirms the completion of the processing.

Hereinafter, the characteristic effects of the data distribution system according to this embodiment will be summarized.

(a) For content that cannot be sold, the supplier can pay for it and call for its use, thereby encouraging its use.

(b) For content that can be sold, the right to use can be lent by the user for a fee.

(c) Users of the data should consider content that is popular and scarce Usage fees are determined according to market principles, such as paying “expensive” fees, or paying “lower” fees for low-margin, high-selling products that are popular.

(d) The quality of encoding of unsold content can be reduced, and the usage fee can be reduced.

(e) Content that sells can have higher encoding quality and higher usage fees.

(f) Low-quality encoded content can be delivered to users who offer low prices.

(g) High quality encoded content can be delivered to users who have offered high prices.
