Description

  The present invention relates to a karaoke network system, and more particularly, to a technique for evaluating performance such as singing and dancing by a user during karaoke performance that has been posted.

  2. Description of the Related Art Conventionally, there is known a karaoke network system that uploads a singing by a singer recorded during a karaoke performance from a karaoke device to a host server and publishes the uploaded singing voice so that it can be viewed from another karaoke device or a personal computer.

  In Patent Document 1, if the singing result of the singer in the karaoke apparatus is equal to or higher than a predetermined score, the singing voice signal is uploaded to the server apparatus, and the server apparatus examines the singing again and registers it as a guide vocal. When it is determined that the conditions to be satisfied are satisfied, a technique is disclosed in which this is disclosed as a guide vocal to all karaoke apparatuses and can be downloaded and used.

  However, in the technique described in Patent Document 1, when this song is examined again by the server device, an evaluation engine that evaluates features such as pitch, lyrics, and sound quality is used. There was a problem that singing with a good evaluation result did not always attract the viewer's interest.

  On the other hand, in the technique described in Patent Document 2, the degree of interest of the viewer is determined as an evaluation result based on whether or not the viewer has watched the singing voice released as described above.

JP 2003-91291 A (page 5, FIG. 4) Japanese Patent Laying-Open No. 2003-250139 (5th page, FIGS. 3 and 4)

  However, in general, once playback of a song is started, it is often played to the end even if it does not attract much interest, and the technique described in Patent Document 2 does not attract viewers' interest. However, the evaluation was high, but on the other hand, even if a song that attracted the viewer's interest was performed, this could not be reflected in the evaluation results.

  The present invention has been made in view of such a problem, and the object of the present invention is the interest of viewers in the evaluation results of performances such as singing, dancing, and shooting video by a user at the time of posted karaoke performance. It is to provide a technique that reflects the degree.

  The karaoke network system according to claim 1 made to solve the above problems (1: In this column, in order to facilitate understanding of the invention, it is used in the “Mode for Carrying Out the Invention” column as necessary. Is not meant to limit the scope of claims by this code.) Is one or more karaoke devices (4) capable of performing karaoke performance, and music data for the karaoke devices. A karaoke host server (2) that distributes content data including the Internet, and an Internet host server (3) that transmits various types of information to an external information terminal. Each karaoke device and the karaoke host server can transmit and receive data via the first network (200). The karaoke host server and the Internet host server can transmit and receive data via the second network (communication line). The Internet host server can transmit and receive data to and from the information terminal via the third network (200).

Each karaoke apparatus includes performance information input means (26, 27), posted data creation means (12), and posted data transmission means (12).
Among these, the performance information input means can input performance information indicating the performance by the user during the karaoke performance.

  The posted data creation means creates posted data including at least performance information indicating the performance input from the performance information input means and user specifying information for specifying a user. Further, the posted data transmitting means transmits the posted data created by the posted data creating means to the karaoke host server.

  The performance information playback time may be calculated by the posting data creation means of the karaoke device and included in the posting data, or may be calculated by the Internet host server after the posting data is transferred. Good.

On the other hand, the karaoke host server includes registered user storage means (2a), posted data storage means (2b), and registered user determination means (73).
Of these, the registered user storage means stores information related to the registered user.

  Further, the posted data storage means divides the received posted data into the published days indicating the number of days since the posting of the posted data is started, the viewing time indicating the time viewed when accessing the posted data, and the Along with the evaluation result indicating the result of evaluating the posted data, it is stored as registered posted data. The number of days of publication is updated every time the date changes.

  Further, the registered user determining means determines whether or not the user specifying information included in the received post data matches one of the registered user specifying information specifying the registered user stored in the registered user storage means. If the registered user identification information for identifying the registered user stored in the registered user storage means matches one of the registered user identification information, the received posted data is determined to be data by the registered user, and the received posting is received. The data is stored in the posted data storage means.

The Internet host server also includes posted data distribution means (83) and posted data evaluation means (83).
The posted data distribution means publishes posted data included in the registered posted data stored in the posted data storage means of the karaoke host server as viewable information, and responds to a request from the viewer via the information terminal. Each time the posted data is distributed, the viewing time information is calculated, and the calculated viewing time information is registered in the registered post data corresponding to the viewed post data. Note that “public” means a state accessible from an external information terminal.

  Further, the posted data evaluation unit is a value obtained by dividing each corresponding viewing time by the playback time for each posted data included in the registered posted data stored in the posted data storage unit when a predetermined evaluation execution condition is satisfied. The evaluation result is calculated by dividing the total sum of the number by the number of publication days, and the evaluation result registered in the corresponding registered post data is updated to the calculated evaluation result.

Thus, the degree of interest of the viewer can be reflected in the evaluation result of performance such as singing, dancing, and shooting video by the user at the time of posted karaoke performance.
The present invention can also be realized as an Internet host server used in the karaoke network system according to claim 1 (claim 2).

  Examples of the performance include singing by the user during the karaoke performance, dancing by the user during the karaoke performance, and an image captured by the user during the karaoke performance. Further, the performance information includes information indicating the singing voice recorded by the user during the karaoke performance, and information indicating the video imaged during the karaoke performance (Claim 3).

Further, when calculating the evaluation result, the viewing time may be weighted based on the level of the viewer who has viewed the posted data (claim 4).
As a result, the viewing time of the content with higher reliability of the evaluation score for the posted data becomes longer by placing more emphasis on viewing by a highly reliable viewer, so that the degree of interest of the viewer is further reflected. Can do.

  In addition, when the karaoke device performs scoring for performance information included in the post data to be evaluated, the viewing time may be weighted based on the scoring result (claim 5).

  As a result, the lower and better post data is reflected in the viewing result, and the better the singing post data, the better the viewing result. As a result, post data from a singer who is good at singing, that is, content that is highly reliable for performance, is less likely to have an evaluation score less than the reference value, and is difficult to be deleted. In other words, since highly reliable content can be left as long as possible, the degree of interest of the viewer can be further reflected.

  As specific examples of the evaluation execution conditions, for example, when a preset time such as midnight is reached, or when the quantity of posted data stored in the posted data storage means reaches a preset quantity, For example, when the amount of posted data stored in the posted data storage unit reaches a preset data amount.

  Further, when the posted data update means satisfies a predetermined update execution condition, it is considered that the posted data whose corresponding evaluation result is less than a preset reference value is deleted from the posted data storage means (claim 6). . It should be noted that post data that has been published for less than a predetermined period may not be deleted.

  As a specific example of the update execution condition, for example, when a preset time such as midnight is reached, or when the quantity of posted data stored in the posted data storage means reaches a preset quantity, For example, when the amount of posted data stored in the posted data storage unit reaches a preset data amount.

  In this way, it is possible to save the storage capacity of the posted data storage means while leaving the posted data that is of interest to the viewer by deleting the posted data that the viewer did not show interest in. Also, for example, when the storage capacity of the posting data storage means allocated for each poster is limited, the posting data is deleted from the posting data that does not attract the viewer's interest that is considered to be a problem even if it is deleted for the poster Thus, it is possible to post the next posting data while leaving the posting data that attracts the viewer's interest that is important to the poster.

[2. Description of Various Processes Executed by Web Server 3a of Internet Host Server 3]
Next, various processes executed by the control unit 83 of the Web server 3a of the Internet host server 3 will be described in order.

[2.1. Explanation of viewing time measurement process]
Hereinafter, a processing procedure of the viewing time measurement process executed by the control unit 83 of the Web server 3a of the Internet host server 3 will be described with reference to the flowchart of FIG.

  This process is executed when a playback application for viewing post data is executed on the user terminal 6 and specific post data is selected from the personal web page on the playback application.

  First, in S105, the playback time counter for counting the playback time of the content is set to zero. Note that this playback time counter indicates that the playback flag is a numerical value “1” every time the timer elapses in a playback time counting process (see FIG. 7, which will be described later) that is repeatedly executed in parallel with the viewing time measurement process. "Is counted up.

  Note that, when the playing flag is set to a numerical value “1”, it indicates that the content is being played back. On the other hand, when the playing flag is set to a numerical value “0”, the content is being played. Indicates that no playback is taking place.

  In subsequent S110, based on the operation instruction from the user terminal 6, it is determined whether or not the “reproduction application end” button for performing the operation instruction to end the reproduction application is pressed. When it is determined that the “reproduction application end” button has not been pressed (S110: NO), the process proceeds to S135. On the other hand, when it is determined that the “reproduction application end” button has been pressed (S110: YES), the reproduction flag is set to a numerical value “0” (S115), and the value of the reproduction time counter is set in the posted data management table. Additional registration is made to the corresponding posted data (S120), and the examination level value (weight) of the viewer who has played this content is additionally registered to the corresponding posted data in the posted data management table (S125). A value obtained by multiplying the examination level value by the time is added to the total viewing time (S130), and this process is terminated.

  Note that the viewer's examination level value may be set based on the number of views by the viewer registered in advance, viewing frequency, viewing time, presence / absence of comments at the time of viewing, and the like. As an example of the level setting based on the number of times of viewing, a counter is provided for each viewer that increases the number of times of viewing every time an affirmative determination is made in S150 (described later) of this processing, and the value is stored in the HDD 72 as an examination level value. Remember. When the number of viewing times is 5 or less, the examination level value is set to a numerical value “1”, and when the number of viewing times is 6 to 10 times, the examination level value is set to a numerical value “1.5”. When the number of viewing times is 11 times or more and 20 times or less, the examination level value is set to a numerical value “2.0”. In other words, in general, the more content is viewed and the more the number of views, the more familiar you are with the review, so the accuracy of the review is likely to improve, so set the review level value to increase with the number of views Keep it.

  As a result, in S520 of “post data management table update processing” to be described later, the larger the examination level value, the lower the possibility that the evaluation score will be less than the reference value, and the more difficult the deletion is. It is possible to leave highly reliable content as long as possible.

  In S135, based on the operation instruction from the user terminal 6, it is determined whether or not the “play” button for performing the operation instruction to reproduce the content has been pressed. If it is determined that the “play” button has not been pressed (S135: NO), the process directly returns to S110. On the other hand, if it is determined that the “play” button has been pressed (S135: YES), content playback is started (S140), the playing flag is set to a numerical value “1” (S145), and the process proceeds to S150. .

  In continuing S150, based on the operation instruction from the user terminal 6, it is judged whether it reproduced | regenerated to the end of content data. If it is determined that the content data has been played to the end (S150: YES), the playing flag is set to a numerical value “0” (S160), and the process returns to S110. On the other hand, when it is determined that the content data has not been reproduced to the end (S150: NO), the process proceeds to S155.

  In S155, based on the operation instruction from the user terminal 6, it is determined whether or not the “Cancel” button for performing an operation instruction for canceling various operations such as content reproduction has been pressed. If it is determined that the “Cancel” button has been pressed (S155: YES), the playing flag is set to a numerical value “0” (S160), and the process returns to S110. On the other hand, if it is determined that the “Cancel” button has not been pressed (S155: NO), the process proceeds to S165.

  In S165, based on the operation instruction from the user terminal 6, it is determined whether or not a “stop” button for performing an operation instruction to stop various operations such as content playback has been pressed. If it is determined that the “stop” button has been pressed (S165: YES), the playback of the content is stopped and the playback flag is set to a numerical value “0” (S185), and the process returns to S150. On the other hand, when it is determined that the “stop” button has not been pressed (S165: NO), the process proceeds to S170.

  In S170, based on the operation instruction from the user terminal 6, it is determined whether or not the “rewind” button for performing the operation instruction to move the content reproduction position in the head direction has been pressed. If it is determined that the “Rewind” button has been pressed (S170: YES), the content being played back is played back and the playing flag is set to “0” (S190), and the process returns to S150. On the other hand, when it is determined that the “rewind” button has not been pressed (S170: NO), the process proceeds to S175.

  In S175, based on the operation instruction from the user terminal 6, it is determined whether or not the “fast forward” button for performing the operation instruction to move the content reproduction position in the rear end direction is pressed. If it is determined that the “fast forward” button has been pressed (S175: YES), the currently playing content is played back in fast forward and the playing flag is set to “0” (S195), and the process returns to S150. On the other hand, when it is determined that the “fast forward” button has not been pressed (S175: NO), the process proceeds to S180.

  In S180, based on the operation instruction from the user terminal 6, it is determined whether or not the “play” button has been pressed. If it is determined that the “play” button has been pressed (S180: YES), the content is normally played and the playing flag is set to “1” (S200), and the process returns to S150. On the other hand, if it is determined that the “play” button has not been pressed (S180: NO), the process directly returns to S150.

Note that according to the above-described viewing time measurement process, the viewing time is measured as follows.
As illustrated in FIG. 5A, the viewing time when a content having a playback time of 2.5 minutes is normally played back continuously from the beginning to the end is measured as 2.5 minutes.

  Further, as illustrated in FIG. 5B, the content having a playback time of 2.5 minutes is normally played back for 1.5 minutes from the beginning, and then paused, and then the playback is resumed for the remaining 1.0 minutes. The viewing time for normal playback is also measured as 2.5 minutes.

  Further, as illustrated in FIG. 5C, the content of the first 1.0 minute out of the content having the reproduction time of 2.5 minutes is very interesting for the viewer, and the corresponding portion is reproduced by repeating rewinding and reproduction. The viewing time when playing back times is measured as 4.0 minutes.

  Note that rewind playback is not counted in the viewing time because it is considered that the head of the part to be viewed again is being searched. Also, fast-forward playback is not counted in the viewing time because it is considered that a portion that is not of interest to the viewer is skipped.

[2.2. Explanation of playback time counting process]
Hereinafter, the processing procedure of the reproduction time counting process executed by the control unit 83 of the Web server 3a of the Internet host server 3 will be described with reference to the flowchart of FIG.

This process is repeatedly executed independently of other processes when the Internet host server 3 is powered on.
First, in S205, it is determined whether or not the built-in timer has elapsed for 1 second. If the built-in timer has not elapsed for 1 second (S205: NO), this process is returned, and S205 is repeatedly executed until the built-in timer has elapsed for 1 second. On the other hand, when the built-in timer has elapsed for 1 second (S205: YES), the process proceeds to S210.

  In S210, it is determined whether or not the playing flag is set to a numerical value “1”. If the in-reproduction flag is not set to the numerical value “1” (S210: NO), it is determined that it is not necessary to count up the reproduction time counter because the content is not reproduced, and this process is returned. On the other hand, when the playing flag is set to the numerical value “1” (S210: NO), it is determined that the playing time counter needs to be counted up because the content is played, and the process proceeds to S215. .

In S215, the reproduction time counter is counted up. Then, this process is returned.
[2.3. Explanation of score calculation process]
Hereinafter, the processing procedure of the score calculation process will be described with reference to the flowchart of FIG.

This process is executed independently of other processes when the power of the Internet host server 3 is on, for example, when a preset time such as midnight is reached.
First, in S305, the quantity of content registered in the posted data management table is acquired and input to the content number counter A which is a counter. The content number counter A is a counter indicating the number of contents for which the evaluation score is calculated.

  In subsequent S310, it is determined whether or not the score calculation has been completed for all the contents registered in the posted data management table. When it is determined that the score calculation has been completed for all the contents (S310: YES), this process ends. On the other hand, when it is determined that the score calculation has not been completed for all the contents (S310: NO), the process proceeds to S315. Note that the processing from S315 onward is repeatedly executed until the score calculation is completed for all contents.

In S315, an evaluation score calculation process which is a subroutine for calculating a score for one content is executed.
Hereinafter, the processing procedure of the evaluation score calculation process which is a subroutine of this process will be described with reference to the flowchart of FIG.

First, in S405, the number of viewing times of one content is acquired, and the acquired number of viewing times is set in the viewing number counter.
In subsequent S410, the “content scoring work” for recording the content score is cleared to zero.

  In subsequent S415, it is determined whether or not the calculation of all viewing results regarding the content being calculated has been completed. When it is determined that calculation of all viewing results has not been completed (S415: NO), an uncalculated viewing result is selected, and a weighting factor for each judge (viewing level value of the viewer) for viewing time. The viewing result is calculated by dividing the value multiplied by the reproduction time of the corresponding content (S420), the calculation result is added to the content scoring work (S425), and the viewing number counter is counted down (S430). , Return to S415. Note that the processes of S420 and S425 are repeatedly executed until the calculation of all viewing results regarding the content being calculated is completed. Note that the value of the content score work when this calculation is completed corresponds to the total viewing time. If it is determined that all viewing results have been calculated (S415: YES), the number of publication days of the corresponding content is calculated by dividing the posting date from the current date (S435), and the content scoring work Is divided by the number of days of publication to calculate an evaluation score for the corresponding content (S440).

  Then, this subroutine is terminated, and the process returns to the score calculation process. That is, when the subroutine (evaluation score calculation process) for calculating the score for one content in S315 is completed, the process proceeds to S320.

In S320, the score (total viewing time and evaluation score) calculated in the subroutine is written in the corresponding posted data in the posted data management table.
In subsequent S325, the content number counter A is counted down. Then, the process returns to S310.

[2.4. Explanation of post data management table update processing]
The post data management table update process executed by the control unit 83 of the Web server 3a of the Internet host server 3 will be described below with reference to the flowchart of FIG.

This process is executed independently of other processes when the power of the Internet host server 3 is on, for example, when a preset time such as midnight is reached.
First, in S505, the quantity of content registered in the posted data management table is acquired and input to the content number counter B which is a counter. Note that the content number counter B is a counter indicating the number of contents for which the evaluation score is calculated.

In subsequent S510, a numerical value “0” is input to N.
In subsequent S515, N is incremented.
In subsequent S520, it is determined whether or not the evaluation score of the Nth content among the content registered in the posted data management table is less than the reference value. When it is determined that the evaluation score of the Nth content is not less than the reference value and the evaluation score is greater than or equal to the reference value (S520: NO), the content is likely to be content that attracts the viewer's interest. Therefore, it is determined not to be a deletion target, and the process returns to S515 to set the evaluation target as the next content. On the other hand, when it is determined that the evaluation score of the Nth content is less than the reference value (S520: YES), it is determined that the content does not attract the viewer's interest, and the process proceeds to S520.

  In S525, it is determined whether or not a predetermined period has elapsed from the number of publication days of the Nth content. When it is determined that the predetermined period has not elapsed since the number of days of publication for the Nth content (S525: NO), the evaluation score is low because the sufficient number of days has not elapsed since the start of publication. The process returns to S515 in order to set the evaluation target as the next content. On the other hand, when it is determined that the N-th content has passed a predetermined period from the number of days of publication (S525: YES), the evaluation score is low even though sufficient days have passed since the start of publication. The process is to be deleted, and the process proceeds to S530.

In S530, the corresponding content is registered in the deletion list.
In subsequent S535, it is determined whether or not the value of the content number counter B is the same as the value of N. When it is determined that the value of the content number counter B is not the same as the value of N (S535: NO), there is a content that has not been determined whether or not deletion is possible. Therefore, the process returns to S515 to set the evaluation target as the next content. On the other hand, when it is determined that the value of the content number counter B is the same as the value of N (S535: YES), since all the contents registered in the posted data management table have been evaluated, it is deleted. In order to delete the content registered in the list from the posted data management table, the process proceeds to S540.

In S540, the content registered in the deletion list is deleted from the post data management table. In this case, the content number counters B and N and the deletion list are initialized. Then, this process ends.
[3. Effects of the embodiment]
(1) As described above, according to the karaoke network system 1 of the present embodiment, even when the content is not reproduced from the beginning to the end, when the content attracts the viewer's interest, the total viewing time is set. Paying attention to the reflection, by executing the above-mentioned viewing time measurement process, the viewing time becomes the basis of the evaluation result for the content such as singing, dancing, and shooting video by the user at the time of posted karaoke performance The degree of interest of the viewer can be reflected.

  (2) Also, according to the karaoke network system 1 of the present embodiment, when calculating the evaluation score (evaluation result) for the posted data, the viewing time is calculated based on the examination level value of the viewer who viewed the posted data. The weighting is performed for them. As a result, more emphasis is placed on viewing by highly reliable viewers, so that the viewing time of content with higher evaluation score reliability on post data becomes longer, so the degree of interest of the viewer can be further reflected. it can.

(3) Also, according to the karaoke network system 1 of the present embodiment, by executing the above-described post data management table update process, by deleting post data that the viewer did not show interest, it is possible for the viewer. The storage capacity of the database 2b of the karaoke host server 2 can be saved while leaving the posted data of interest. In addition, for example, when the storage capacity of a personal Web page allocated for each registered user is limited, it is deleted from post data that does not attract viewers' interest even if it is deleted for registered users. Thus, it is possible to post the next posting data while leaving the posting data that attracts the viewer's interest which is important for the registered user.
[4. Other Embodiments]
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, It is possible to implement in the following various aspects.

  (1) In the above embodiment, the score calculation process is executed when a preset time such as midnight is reached, but is not limited to this. For example, the score calculation process is performed in the database 2b of the karaoke host server 2. The above-described score calculation process may be executed when the quantity of registered post data reaches a preset quantity. Further, for example, when the amount of post data registered in the database 2b of the karaoke host server 2 reaches a preset data amount, the above-described score calculation process may be executed.

  (2) In the above embodiment, the post data management table update process is executed when a preset time such as midnight is reached, but is not limited to this. The post data management table update process described above may be executed when the quantity of post data registered in the database 2b reaches a preset quantity. Further, for example, when the amount of posted data registered in the database 2b of the karaoke host server 2 reaches a preset data amount, the above-described posted data management table update processing may be executed.

  (3) When the karaoke scoring score is registered in the posted data, the evaluation score for the posted data may be weighted by the karaoke scoring score. Specifically, the evaluation score is multiplied by a weighting coefficient corresponding to the karaoke scoring score. As an example of setting the weighting coefficient, when the karaoke scoring score is 50 points or less, the weighting coefficient is set to “1”, and when the karaoke scoring score is 51 points or more and 80 points or less. The weighting coefficient is set to a numerical value “1.2”, and when the karaoke scoring score is 81 points or more, the weighting coefficient is set to a numerical value “1.5”.

  As a result, if the “judgment weight” in S420 of the above-described score calculation process is replaced or added to the “scoring weight”, the poor post data will be reflected in the viewing result, so the post data that is good for singing The better the viewing results. As a result, in S520 of the post data management table update process described above, post data by a singer who is good at singing, that is, content that is highly reliable for performance, is less likely to have an evaluation score below the reference value. It becomes difficult to be deleted. In other words, since highly reliable content can be left as long as possible, the degree of interest of the viewer can be further reflected.

  Further, the same effect can be obtained even if the karaoke scoring score is normalized and added to the evaluation score.
