For example, in Patent Document 1, there is a voting method in which gratuitous voters who have normal points given free of charge and paid voters who have extra points given for a fee are allowed to vote within the range of their respective points. disclosed.

JP-A-2002-245225

In the voting method described in Patent Document 1, the voting behavior of paid voters who have extra points tends to greatly affect the final number of votes. Therefore, it is likely that the merits of the candidate songs based on the final number of votes will be determined by mass voting by some paid voters.

The problem to be solved by the present invention is to prevent excessive influence that individual evaluations by some evaluators may have on overall evaluation.

In order to solve the above problems, the present invention adjusts a comprehensive evaluation for an evaluation target according to the actual number of evaluators who have individually evaluated the evaluation target. The present invention includes at least each of the following aspects.

A control method for an information processing device, comprising: an adjustment step of adjusting the overall rating so that it changes when the specified real number fluctuates.

[C] A specific function that identifies the actual number of users who have performed evaluation actions that give individual evaluation levels to an evaluation target, and a total evaluation level that is obtained by accumulating the individual evaluation levels given to the evaluation target by the specific function. A control program that causes a computer of an information processing device to implement an adjustment function that adjusts the total evaluation degree so that it changes when the specified real number fluctuates.

By adjusting the overall evaluation level using the real number, the excessive influence of the second evaluation behavior, which is likely to be repeated, can be suppressed.

(6) The specifying means specifies the actual number of users who have performed the second evaluation behavior using the second element with a looser limit on the number of acquisitions compared to the first element used for the first evaluation behavior. . By adjusting the overall evaluation level using the real number, the excessive influence of the second evaluation behavior, which is likely to be repeated, can be suppressed.

(7) The identifying means identifies the actual number of users who have performed the second evaluation behavior using the second element whose acquisition cost is higher than that of the first element. By adjusting the overall evaluation level with the real number, excessive repetition of the second evaluation behavior can be suppressed.

(9) The identifying means identifies the actual number of users who have performed the evaluation action that can be performed using the electronic information with a defined expiration date. By adjusting the comprehensive evaluation level using the real number, excessive repetition of evaluation behavior can be suppressed.

(10) The specifying means specifies the number of terminals used in the evaluation action as the real number. If the overall evaluation degree is adjusted by the real number, the influence of repetition of evaluation behavior by some evaluators can be suppressed.

(11) The specifying means specifies the actual number of users who have performed the evaluation behavior as the real number. If the overall evaluation level is adjusted by the real number, the influence of repetition of evaluation behavior by some evaluators can be suppressed.

As used herein, the terms are used as follows.

(1) "Evaluation target" can include objects that can be grasped by at least one of the five senses (especially, sight and hearing). Objects can include both living and non-living objects. Objects may include performances and performers performing physical actions that can be perceived visually and/or aurally (eg, vocalizing, moving the body). Objects can also include digital information that can be played on information processing terminals and participants in the digital information. Digital information includes at least one of video information and audio information. Digital information includes, for example, online distribution (eg, live distribution, non-live distribution) and digital content. Online distribution includes, for example, performance videos including video and audio of performances by performers. Performance includes, for example, karaoke singing. Participants involved in digital information include, for example, those involved in online distribution (eg, distributors, performers) and those involved in digital contents (eg, producers, performers).

(2) "Evaluation" refers to judging the value of an evaluation object, such as good/bad, beauty/ugliness, superiority/inferiority, and the like. Values that are determined can include both positive and negative values. The value determined may be limited to positive values.

(3) “Individual Evaluation” means an evaluation by a single person. The method of "individual evaluation" includes, for example, alternative selection of affirmative (negative) or not, alternative selection of affirmative or negative, input of degree of evaluation (e.g., level, score), etc. . The criteria for "individual evaluation" may be arbitrary or may be explicitly specified in advance. The degree of evaluation input by "individual evaluation" is particularly referred to as "individual evaluation degree".

(4) “Comprehensive evaluation” means evaluation obtained by aggregating multiple individual evaluations. The "comprehensive evaluation" tabulation method can include calculation of cumulative values and identification of representative values. When calculating the cumulative value, at least one of the individual evaluations may be weighted according to some criteria. Representative values include, for example, average values and median values. The degree of evaluation obtained by aggregating individual evaluation degrees is particularly referred to as "comprehensive evaluation degree".

(5) “Evaluator” means the subject of individual evaluation. "Evaluators" include, for example, performance viewers, online distribution viewers, and digital content viewers. The "evaluator" perceives the evaluation target with at least one of the five senses, and individually evaluates the evaluation target. The "evaluator", for example, visually, aurally, or audiovisually grasps the object to be evaluated, and makes an individual evaluation of the object to be evaluated.

(6) "Evaluation behavior" refers to behavior in which an evaluator associates his/her individual evaluation with an evaluation target. The “evaluation behavior” may be an offline behavior or an online behavior. Online evaluation actions include, for example, operations using an information processing terminal (evaluation operations). The information processing terminal may be a terminal possessed by an evaluator, or may be a terminal used for evaluation operations by a plurality of evaluators. The evaluation operation may be a designation operation for designating a single element (display element) displayed on the screen of the information processing terminal, or may be a designation operation for designating a single element (display element) displayed on the screen of the information processing terminal. It may be a selection operation to select one from.

(7) "Evaluation behavior" can be divided into "first evaluation behavior" and "second evaluation behavior". The “first evaluation behavior” and the “second evaluation behavior” may be classified, for example, based on the degree of restriction on evaluation, or may be classified according to display elements used for evaluation. For example, it is classified into a “first evaluation behavior” with relatively strict restrictions on evaluation and a “second evaluation behavior” with relatively loose restrictions. Also, for example, "first evaluation behavior" that uses "first element" with relatively strict restrictions on acquisition and "second evaluation behavior" that uses "second element" with relatively loose restrictions classified. Restrictions on evaluation include, for example, the upper limit of the number of individual evaluations by one evaluator for one evaluation object, and the upper limit of the cumulative value of individual evaluation degrees given to one evaluation object by one evaluator.

(8) The "first factor" and the "second factor" may be classified, for example, based on the degree of restrictions on availability. For example, it is divided into a "first element" with relatively strict restrictions on availability and a "second element" with relatively loose restrictions. Restrictions on acquisition include, for example, an upper limit on the number of acquisitions per acquisition procedure, an upper limit on the cumulative number of acquisitions, and an upper limit on the number of possessions.

(9) "real number" means an actual number; The actual number is, for example, the apparent number with duplicates eliminated as much as possible. "Actual number of users who performed evaluation actions" is, for example, the actual number of user accounts that were the subject of evaluation actions or its approximate value, the real number of terminals used for individual evaluation or its approximate value, and the evaluators who performed individual evaluations. contains real numbers or approximations thereof.

(10) The mode of adjustment in the case of adjusting the total evaluation level to change when the real number of users who have performed evaluation actions changes is the mode of adjusting the total evaluation level to increase as the real number increases, and the real number decreases. Then, it includes at least a mode in which the comprehensive evaluation degree is adjusted so as to decrease. In addition, an aspect in which adjustment is made so that the total evaluation degree increases when the actual number of users who have made positive evaluation behavior increases, and the total evaluation degree decreases when the actual number of users who have made negative evaluation behavior increases. may include

(11) "Electronic information" is, for example, information that can be embodied as monetary value, rights, qualifications, position, position, and the like. "Electronic information" is available, for example, in exchange for consideration. The “electronic information” may have an expiration date.

[1. embodiment]
[1-1. overview]
The present embodiment relates to a mechanism for deriving a comprehensive evaluation by synthesizing individual evaluations by a plurality of evaluators on an evaluation target. The evaluation information processing apparatus according to the present embodiment, in order to suppress the excessive influence that the individual evaluation by some evaluators may have on the overall evaluation, determines the actual number of evaluators who have individually evaluated a given evaluation target. It is configured to adjust the overall evaluation for the evaluation object.

[1-2. Evaluation information processing device]
The evaluation information processing apparatus (for example, the server 4) according to the embodiment includes specifying means (for example, the specifying unit 83) for specifying the actual number of users who have performed an evaluation action that assigns an individual evaluation degree to the evaluation target, and adjusting means (for example, an adjusting unit 84) for adjusting the total evaluation obtained by accumulating the given individual evaluation so that the total evaluation changes when the real number specified by the identifying means changes. Prepare.

For example, it is preferable that the adjusting means adjust the comprehensive evaluation degree to increase as the number of users identified by the identifying means increases. Specifically, the adjusting means preferably adjusts the comprehensive evaluation degree using the formulas shown in [Equation 1], [Equation 2], and [Equation 3], for example. Thereby, the user can be induced to take an evaluation action.

[Number 1]
Comprehensive rating=cumulative rating×{1+(weight w1×real number of users)}
(However, w1>0)

[Number 2]
Comprehensive rating=(weight w21×accumulated rating)+(weight w22×real number of users)
(However, w21>0 and w22>0)

[Number 3]
Comprehensive rating=(weight w31×accumulated rating)×(weight w32×real number of users)
(However, w31>0 and w32>0)

Preferably, the identifying means identifies, for example, the actual number of users who performed the evaluation behavior during the live distribution of the evaluation target to be live distributed. As a result, the user who is viewing the live distribution can be guided to take an evaluation action during viewing.

It is preferable that the specifying means specifies, for example, the real number of users who have performed the second evaluation behavior with looser restrictions on evaluation than the first evaluation behavior. This can guide the user to take the second evaluation action.

[2. Example]
[2-1. Overview of Example]
[2-1-1. Overview of Evaluation Function]
In this embodiment, a live distribution (an example of an “evaluation target”) is performed by a viewing user (an example of an “evaluator”) who watches the distribution. (an example.) of the distribution (an example of an “individual evaluation”) to derive a total evaluation score (an example of an “overall evaluation”) for the distribution. In this embodiment, the evaluation function is implemented in a karaoke system that provides a karaoke service (hereinafter referred to as "service of the embodiment").

In the service of the embodiment, when the viewing user who is watching the live distribution of the singing video or the competition singing video performs an evaluation operation targeting the display element displayed on the viewing screen, the score corresponding to the display element is given to the live distribution. The total evaluation score increases as the accumulated accumulated points (accumulated points) increases. The superiority or inferiority of multiple live distributions is determined according to the total evaluation score. In the following, a case will be mainly described in which the individual evaluations made by the viewing users during the live distribution of the competition singing video are synthesized to derive a comprehensive evaluation and determine the superiority or inferiority.

[2-1-2. Main features of display elements]
The display elements include a first element (corresponding to "operation icon 58A" in the following description) and a second element (corresponding to "money throwing effect image" in the following description). The first element and the second element may each have a plurality of types that differ in corresponding score and/or on-screen appearance. Comparing the first element and the second element, for example, there are differences in restrictions on acquisition, acquisition costs, restrictions on use, and corresponding functions (effects to be activated).

(1) Differences in Restrictions on Availability Compared to the first factor, the second factor has looser restrictions on availability. Restrictions on acquisition include, for example, the upper limit of the number of acquisitions per acquisition procedure, the upper limit of the cumulative number of acquisitions, the upper limit of the number of holdings, and the like. In this respect, the second element is likely to be acquired collectively or held in large quantities.

(2) Difference in Acquisition Cost Compared to the first factor, the second factor has a higher acquisition cost. In the service of this embodiment, acquisition of the first element is free, while acquisition of the second element is charged. Specifically, the first element can be obtained automatically (that is, passively) at a predetermined timing before or during viewing of live distribution. On the other hand, the second element can be obtained (that is, actively) by direct or indirect exchange with consideration (monetary value) before or during viewing of the live distribution. In this regard, there is a certain deterrent to large-scale acquisition of the second factor.

(3) Differences in Restrictions on Use Compared to the first element, the second element has looser restrictions on the number of times it can be used. A viewing user of the service of the present embodiment performs an evaluation operation targeting one of the obtained display elements while viewing the live distribution. In the following description, the upper limit of the first evaluation operation using the first element (corresponding to "score input" in the following description) is one per distribution, and the second evaluation operation using the second element The upper limit of the number of evaluation operations (corresponding to "inputting coins" in the following description) is unlimited. That is, the upper limit of the number of times of evaluation by the second evaluation operation (an example of “restrictions on evaluation”) is looser than that for the first evaluation operation. At this point, the second evaluation operation is likely to be iterative.

(4) Differences in Corresponding Functions When the first evaluation operation targeting the first element is performed, the first effect is executed on the screen. On the other hand, when the second evaluation operation targeting the second element is performed, the second effect is executed on the screen. The second rendition is visually or aurally richer than the first rendition. Visually flashy means, for example, that the display area of visual information is large, the display time of visual information is long, the number of colors used for visual information is large, the visual information is often decorative, and the movement of visual information is large. It refers to devices that make the display content stand out directly, such as large size and long visual information movement time. Aurally flashy means that the display content is indirectly conspicuous by reproducing auditory information, playing auditory information for a long time, or playing auditory information at a high volume. . These devices may be made singly or in combination.

[2-1-3. Main features of the evaluation function]
In the service of this embodiment, the total evaluation score is adjusted according to the number of accounts of viewing users who have performed the second evaluation operation. Specifically, the evaluation total score is adjusted by the formula shown in [Formula 4]. Due to this feature, in the service of the present embodiment, the total score, which is a simple accumulated value of points given by the second evaluation operation, may not match the total evaluation score. In other words, even if the accumulated score is inferior, the evaluation total score can be reversed depending on the number of user accounts that have performed the second evaluation operation.

[Number 4]
Evaluation total score = Cumulative score x {1 + (weight w4 x number of accounts)}
(However, w4>0)

[2-2-4. Recording of singing videos by singing users]
A procedure for a singing user to shoot a singing video using the mobile terminal 3A will be described.

A singing user activates a video posting viewing application on the mobile terminal 3A when shooting a singing video. When the moving image posting viewing application is activated, the mobile terminal 3A accesses the server 4 storing a plurality of music data. Then, the singing user arbitrarily selects a song for singing by himself/herself from the moving image posting/listening application, and downloads the song data from the server 4 to the portable terminal 3A. Then, the singing user sings by reproducing the music at an arbitrary timing using the video posting viewing application. The video posting viewing application starts playing the music and also starts shooting a video with the camera 3d. That is, the singing video is a video captured by the mobile terminal 3A while the music is played back from the mobile terminal 3A.

The song data is also associated with lyric data, and when the song data is downloaded from the server 4 to the mobile terminal 3A, the associated lyric data is also downloaded to the mobile terminal 3A. In the following description, it is assumed that song data also includes lyrics data.

FIG. 4 is an example (screen display example) of the display state (hereinafter referred to as "screen display") on the screen 3a of the portable terminal 3A in the procedure of photographing a singing video.

As shown in FIG. 4, the screen 3a is divided into a lyrics display area 50A and a photographed image display area 50B. The lyric display area 50A includes a lyric image 52 indicating the lyrics of the song sung by the user, a pitch image 54 indicating the pitch of the song, and a progress bar 56 indicating the progress of shooting.

The lyric image 52 and the pitch image 54 are updated as the music progresses. In the service of the embodiment, as an example, the lyric image 52 and the pitch image 54 are updated by several phrases and displayed in the lyric display area 50A. Note that the update timing of the lyrics image 52 and the pitch image 54 may be the same or different.

As an example, the lyrics image 52 displays the lyrics in multiple stages (two stages in the example of FIG. 4), and the colors of the lyrics in the upper stage match the progress of the music so that the singing user can grasp the lyrics to be sung at present. Together, it changes from the left end to the right end. When the color change of the lyrics in the upper row reaches the right end, the lyrics in the lower row rise and are displayed in the upper row, and new lyrics are displayed in the lower row. change to the right end.

In the pitch image 54, for example, a plurality of pitch bars 54A are displayed in steps in the horizontal direction according to the intensity of the pitch. Then, the color of the pitch bar 54A changes from the left end to the right end and the pointer 54B moves from the left end to the right end as the music progresses so that the singing user can grasp the pitch of the lyrics to be sung at present. When the color of the pitch bar 54A changes and the pointer 54B reaches the right end, the pitch image 54 showing the next pitch is updated and displayed.

As an example, the progression bar 56 indicates the length of the entire song from the left end to the right end. When the music starts to be reproduced, the pointer 56A indicating the music reproduction position moves from the left end to the right end, and when the pointer 56A reaches the right end, the music ends. The progress bar 56 passed by the pointer 56A is displayed thicker than the position before progress.

Recording of the singing video is started after a predetermined time (for example, 10 seconds) after the singing user selects a song and taps a recording start button (not shown) displayed on the screen 3a. Also, the start and end of video recording may coincide with the start and end of the music, but this is not limiting, and the video recording may start a predetermined time (for example, 5 seconds) before the start of the music. However, the video recording may end after a predetermined time (for example, 5 seconds) after the end of the music.

A singing user connects an earphone to the earphone terminal 3e, listens to the reproduced music using the earphone, and sings along with the music. The mobile terminal 3A shoots the singing user with the camera 3d and records the singing user's singing with the microphone 3c. That is, the microphone 3c does not acquire the sound of the music being reproduced. Then, the portable terminal 3A records the singing voice of the singing user acquired by the microphone 3c and uses it as singing data.

The singing data may be obtained by extracting the frequency band of human voice by filtering. This filtering process removes noise caused by the surrounding environment of the singing user from the singing data, so that the recorded singing voice of the singing user becomes clearer.

Then, the moving image posting viewing application combines the song data and the singing data with the recorded data to create singing moving image data that can be transmitted to the server 4 . As an example, the user can select one of the following two types of timing for transmitting the song video data to the server 4, that is, timing for uploading to the video posting site.

One is live distribution in which a singing user sings and uploads singing video data to a video posting site in real time. In the live distribution, the viewing user will view the singing by the singing user in real time. The other is non-live distribution in which the singing user uploads the singing video data to the video posting site at any timing after the singing of the song is completed.

When live distribution is to be performed, the singing user performs settings for live distribution before recording the singing video, so that the singing video data is uploaded to the video posting site at the same time as the recording of the video is started. In the case of live distribution, the singing video data may be uploaded to the video posting site without being stored in the mobile terminal 3A.

In addition, as settings for live distribution, the first live distribution setting allows the viewing user to view the singing video in live distribution, and the second live distribution setting allows the viewing user to view the singing video even after the live distribution. Any of the settings can be set by the singing user. That is, in the first live distribution setting, when the live distribution ends, the singing video data is deleted from the server 4, and the viewing user cannot view the live-distributed singing video after the live distribution ends. On the other hand, in the second live distribution, the server 4 continues to store the singing video data even after the live distribution ends, so that the viewing user can view the singing video as a non-live distribution even after the live distribution ends.

In the case of non-live distribution, the singing video data is temporarily stored in the mobile terminal 3A, and the singing user operates the video posting viewing application to upload the singing video to the video posting site at any timing.

[2-2-5. Viewing of singing video by viewing user]
A procedure for the viewing user to view the singing video using the mobile terminal 3B will be described.

When viewing a singing video, the viewing user activates the video posting viewing application on the mobile terminal 3B. When the video posting viewing application is activated, the mobile terminal 3B accesses the server 4 storing a plurality of singing video data, that is, the video posting site. Then, the viewing user selects a singing video to be viewed via the video posting viewing application and displays it on the screen 3a. An example of the method of distributing the singing video to the mobile terminal 3B by the server 4 is streaming distribution.

FIG. 5 shows an example of the screen display of the mobile terminal 3B in the viewing procedure of the singing video, and shows the screen display when the live distribution is being performed.

A singing video is displayed on the screen 3a, and a singing user display area 50C, a lyrics display area 50D, and a comment input display area 50E are provided. The singing user display area 50C, the lyrics display area 50D, and the comment input display area 50E may be superimposed and displayed on the singing video.

The singing user display area 50C displays the user name of the singing user who posted the singing video, whether or not it is a live distribution, and the name of the song being sung.

The lyrics of the singing video are displayed in the lyrics display area 50D. The displayed lyrics are, for example, a plurality of phrases each, and the color of the lyrics changes from the left end to the right end as the music progresses. As an example, the lyrics display area 50D may display the lyrics in a plurality of stages. In this case, when the change in the color of the lyrics in the upper row reaches the right end, the lyrics in the lower row rise and are displayed in the upper row, and new lyrics are displayed in the lower row. changes from the left end to the right end.

In the comment input display area 50E, a comment input field is displayed, and the comments of the viewing user who is viewing the singing video are displayed together with the user name. As an example, each time a comment is input by the viewing user, the comment is additionally displayed at the top of the comment input display area 50E, and the comments that have been displayed up to that point are moved downward. When the comment cannot be displayed in the comment input display area 50E, a scroll bar (not shown) is displayed on the right side of the comment display area. Comments that were not displayed in 3a are displayed.

Further, the screen 3a displays operation icons 58A to 58D for the viewing user to perform various operations.

The operation icon 58A is an icon that is tapped when the viewing user sympathizes with the singing video that the viewing user is watching, and the total number of taps of the operation icon 58A for the singing video is displayed above the operation icon 58A. be.

The operation icon 58B is an icon that is tapped when the viewing user requests a competition (hereinafter referred to as "competition singing") against the singing user who is live-distributing the singing video displayed on the screen 3a. In the competition singing, a plurality of singing videos (first singing video, second singing video) by different singing users are displayed simultaneously on the screen 3a of the mobile terminal 3B of the viewing user, and the singing video alternately sings the same song. be. That is, the viewing user who taps the operation icon 58B becomes the singing user who performs the competition singing.

The operation icon 58C is an icon that is tapped when the viewing user makes various settings for the video posting viewing application.

The operation icon 58D is an icon that is tapped by the viewing user when superimposing a decoration image on the singing video displayed on the screen 3a. The decorative image in the service of the embodiment has a monetary value determined by its type, and the viewing user obtains it by exchanging the monetary value (for example, payment of cash, consumption of virtual currency, consumption of points). It is possible. Then, the viewing user taps the operation icon 58D to superimpose the decoration image on the singing video that the viewing user is viewing. The singing user of the singing video on which the decoration image is superimposed receives money corresponding to the superimposed decoration image from the operator of the video posting site. That is, the superimposition (display instruction) of the decoration image on the singing video by the viewing user corresponds to a so-called tipping for the singing user.

[2-2-6. Overview of the competition singing function]
The video posting and viewing application supports a battle function in which multiple users who are performers compete with each other for the superiority of their own performance videos. The competition function in the service of the embodiment is a kind of so-called karaoke battle, and as illustrated in FIG. It is a competition singing function displayed simultaneously on the screen 3a of the portable terminal 3B. It should be noted that the competition singing function is a function executed by the server 4 .

FIG. 6 is a screen display example of the mobile terminal 3B of the viewing user in the competition singing. The display of "VS" shown in FIG. 6 is displayed at the start of the competition song, and the display is stopped after a predetermined time (for example, 3 seconds) has passed since the competition song was started. Also, the screen display of the singing user's portable terminal 3A may be, for example, the same as that shown in FIG. (See FIG. 8, which will be described later).

In order for the competition singing to be performed, a singing user (hereinafter referred to as "first singing user") requests another singing user (hereinafter referred to as "second singing user") to simultaneously distribute singing videos (hereinafter referred to as (referred to as a "competition request") is made, and the second singing user needs to approve the competition request.

More specifically, the first singing user activates the video posting viewing application on his/her mobile terminal 3A1, and transmits a competition request to the second singing user who is live-distributing the singing video using the video posting viewing application. . The competition request is sent by the first singing user tapping the operation icon 58B. The music to be sung in the competition singing is selected by the first singing user. Information (title and singer name) indicating the selected song (hereinafter referred to as "match song") is sent to the second singing user together with the match request.

The competition request transmitted from the mobile terminal 3A1 is transmitted via the server 4 to the mobile terminal 3A2 of the second singing user. An image corresponding to the received competition request is displayed on the screen 3a of the mobile terminal 3A2, and the second singing user taps a predetermined image displayed on the screen 3a when accepting the competition request.

Then, when the second singing user accepts the competition request from the first singing user, the server 4 determines that the first singing video 60A by the first singing user and the second singing video 60B by the second singing user are on the mobile terminal 3B. By distributing so as to be displayed on the screen 3a at the same time, the competition singing is started. As a result, the viewing user can view the competition singing (real-time competition) between the first singing user and the second singing user in real time. In addition, in the following description, the 1st singing animation 60A and the 2nd singing animation 60B distributed in competition singing are named generically, and are also called a competition singing animation.

In this way, the competition singing function accepts a singing video competition request from the first singing user to the second singing user, and when the second singing user approves the competition request, the first singing video 60A and the second singing The video 60B is distributed so as to be simultaneously displayed on the screen 3a of the portable terminal 3B. Therefore, the competition singing function enables singing users to compete with each other in their own singing by using respective singing videos, and enables viewing users to simultaneously view a plurality of competing singing videos.

It is also assumed that the second singing user accepts the match request but does not accept the match song. For such a case, the competition singing function transmits information indicating the competition song change and the competition song selected by the second singing user from the second singing user's mobile terminal 3A2 to the first singing user's mobile terminal 3A1. and may have a function of requesting the approval of the first singing user.

[2-2-6-1. Alternate Singing in Competition Singing]
In the competition singing function according to the embodiment, the first singing user and the second singing user alternately sing the same song (hereinafter referred to as "alternate singing").

Alternating singing may be, for example, a form in which the second singing user sings the same song after the first singing user has finished singing one song. As shown, music is virtually divided into a plurality of areas, and the order of singing users who sing for each divided area 68 is set (hereinafter referred to as "alternate performance setting"). As a result, the first singing user and the second singing user alternately sing the same song according to the alternating performance setting, so the viewing user can check the singing ability of the first singing user and the second singing user. You can clearly recognize the difference and enjoy the competition singing more. In the following description, the order of singing users who sing is referred to as alternate singing order.

The competition singing function, for example, allows the singing user to recognize the divided area 68 in which the singing user himself/herself sings by highlighting the lyric portion sung by the singing user. The highlighting is a color change, a thickness change, or the like of the lyrics.

In the example of FIG. 7, the divided area 68 is set so that the first singing user and the second singing user sing alternately, and the divided area 68 where the first singing user and the second singing user sing together. is also set. The divided areas 68 are set in advance based on, for example, the phrase, chorus, bar, etc. of the music, and the time length of each divided area 68 does not necessarily have to be the same.

The alternate singing order is determined along with the decision to perform the competition singing. For example, it is set so that the first singing user who requested the competition sings first, and the second singing user sings later. Note that the divided area 68 in which the first singing user and the second singing user sing together may be set in advance for each piece of music.

Also, the alternate singing order set based on the divided areas may be changed dynamically. For example, a singing user with a relatively high total score obtained by an evaluation function, which will be described later, may have more divided regions 68 for singing. More specifically, the total score for each singing user (singing video) is compared for each predetermined timing of the song, and the singing user with a relatively large total score continues the plurality of divided areas 68 after that. sing. In this case, the maximum number of divided areas 68 that can be continuously sung is predetermined.

As a result, a singing user with a relatively high total score has more divided regions 68 to sing, while a singing user with a relatively low total score has fewer divided regions 68 to sing from. Therefore, a singing user with a relatively high total score appeals more to the viewing user with his or her singing ability, and is more likely to attract the viewing user.

[2-2-6-2. Screen display and audio output during alternate singing]
As described above, FIG. 6 is the display screen of the viewing user's mobile terminal 3B in the competition singing, and both the first singing video 60A and the second singing video 60B are displayed in the same image size. Then, a display (“NOW PLAYING” in FIG. 6) that allows the viewing user to recognize the singing video in which the song is being performed is performed.

Here, a singing video and its voice that are not being sung are not of interest to the viewing user, and may rather distract the attention of the viewing user who is watching the song being sung.

Therefore, in the service of the embodiment, the singing video is delivered to the portable terminal 3B so that the voice of the singing video during singing is output and the voice of the singing video during which singing is not being performed is not output. Further, the server 4 distributes the singing video to the mobile terminal 3B so that the singing video during singing is displayed on the screen 3a of the mobile terminal 3B in a larger size than the singing video when the song is not being performed. As a result, the viewing user can view the competition singing video without being distracted by the singing video that is not currently being sung.

FIG. 8 is an example of a screen display of the portable terminal 3B in competition singing. In the example of FIG. 8, the first singing video 60A is in the middle of singing, and the second singing video 60B is not in the middle of singing. The 2-song video 60B is displayed in a reduced size (window display). The image size and the display position on the screen 3a when the singing video is displayed in reduced size may be determined in advance, or the viewing user may be able to change the image size and screen position to any desired size.

In addition, in the service of the embodiment, the first singing video 60A and the second singing video 60B are output as audio, or the screen display of the first singing video 60A and the second singing video 60B is performed based on the above-described alternate singing order. A singing video is distributed to the portable terminal 3B as shown in FIG.

That is, in the divided area 68 where the first singing user sings, the sound of the first singing video 60A is output and the first singing video 60A is displayed enlarged, while the sound of the second singing video 60B is not output. , the second singing video 60B is displayed in reduced size. In addition, in the divided area 68 where the second singing user sings, the sound of the second singing video 60B is output and the second singing video 60B is enlarged and displayed, while the sound of the first singing video 60A is not output. , the first singing video 60A is displayed in reduced size. In addition, in the divided area 68 where the first singing user and the second singing user sing together, the first singing video 60A and the second singing video 60B are displayed on the screen with the same image size as shown in FIG. Audio is output together.

Thus, in the service of the embodiment, since the voice output and screen display of the competition singing video are controlled based on the above-described alternate performance setting, even if the singing video is displayed at the same time, the mobile terminal of the viewing user The output control of the competition singing video in 3B can be easily performed.

[2-2-6-3. Evaluation function]
The video posting viewing application has an evaluation function that receives an input of evaluation for each battle singing video (hereinafter referred to as "evaluation behavior") from the viewing user's mobile terminal 3B. The evaluation actions include a first evaluation action that associates a positive emotion with respect to the singing video, and a second evaluation action that associates a positive degree with respect to the singing video.

(1) Impression evaluation by the first evaluation action and first production Input is made by the viewing user performing the first evaluation operation (tapping) on the icon 58A. In other words, when the viewing user sympathizes with the singing video, the viewing user taps the operation icon 58A as an indication of favorable evaluation of the singing video. In the competition singing, an image showing the progress of the impression evaluation for each received singing video (hereinafter referred to as "impression evaluation progress image") 66 is displayed on the screen 3a of the mobile terminal 3B together with the singing video. Delivered (first production).

As described above, the evaluation function according to the embodiment enables the viewing user to evaluate the impression of the singing video by tapping the operation icon 58A by the viewing user. Therefore, when the competition singing is performed, the viewing user can participate in the competition singing according to the impression evaluation. It should be noted that the viewing user can evaluate the impression of one singing video and also evaluate the impression of the other singing video.

In the service of the embodiment, impression evaluation is input when the operation icon 58A is tapped once. The numbers (21 and 185) of the impression evaluation progress image 66 shown in FIGS. 6 and 8 are the number of impression evaluation acquisitions for each singing user (singing video), and are extended to the left and right of the screen 3a and hatched (color) on the left and right. Different bar images relatively show the number of impression evaluation acquisitions for each singing video.

In addition, an upper limit is provided for the number of times each viewing user can tap the operation icon 58A (hereinafter referred to as "tap upper limit"), and the tap upper limit is one in the service of the present embodiment. Then, when the tap upper limit is satisfied, an operation icon 58D is displayed on the screen 3a instead of the operation icon 58A as shown in FIG.

(2) Score Evaluation by Second Evaluation Behavior and Second Effect By tapping the operation icon 58D, the viewing user creates a decorative image (hereinafter referred to as a “money-throwing effect image”) for the singing video corresponding to the tapped operation icon 58D. ) can be superimposed (second effect). Thus, the evaluation function has a coin-throwing effect function of receiving an instruction to superimpose a coin-throwing effect image on the singing video from the portable terminal 3B and superimposing a coin-throwing effect image corresponding to the received instruction on the singing video. In the following description, the display instruction (selection) of the coin-throwing effect image by the viewing user via the mobile terminal 3B is referred to as the coin-throwing input as described above.

That is, since the viewing user decorates the singing video by superimposing the coin-throwing effect image 69 on the singing video that he/she sympathizes with, the coin-throwing effect function excites the viewers and the singing video itself during distribution of the singing video. be able to. Note that the coin-throwing effect function is a function executed by the server 4 in response to a display instruction from the viewing user via the video posting viewing application.

FIG. 9 shows a screen display of the mobile terminal 3B that transitions when the viewing user presses and holds the operation icon 58D, and a plurality of different coin effect images 69 selectable by the viewing user are displayed. A required point is set for each of the coin-throwing effect images 69, and the design differs according to the required points. The viewing user selects one of the plurality of coin-throwing effect images 69 displayed on the screen, which can be obtained with points owned (an example of “electronic information”). Note that different designs refer to, for example, different shapes, colors, or directions.

As an example, a charge amount is determined for each point, and the viewing user purchases the points, and the types of the coin effect images 69 that can be selected increase or decrease according to the points owned. When the viewing user selects the coin-throwing effect image 69 , the points owned by the viewing user are reduced according to the required points of the selected coin-throwing effect image 69 . It should be noted that the points may be increased by using other online services, etc., in addition to the acquisition by billing. Also, the points may have an expiration date. The term of validity may be set by date, time, etc., or may be set as the end of the term of validity starting from a certain reference time.

The coin-throwing effect image 69 illustrated in FIG. 9 is four types of spotlight images that simulate spotlights with different directions and spread out, and four types of merged spotlight images each having a different color by combining a plurality of spotlight images. By setting the coin-throwing effect image 69 as an image simulating a spotlight, the viewing user can feel as if he/she is participating in a concert or the like. Note that the coin-throwing effect image 69 is not limited to the example shown in FIG. 9, and may be another image.

FIG. 10 is an example of a singing video (hereinafter referred to as “effect-superimposed singing video”) in which the combined spotlight image is selected by the viewing user as the coin-throwing effect image 69 and the coin-throwing effect image 69 is superimposed. The effect-superimposed singing video can be viewed not only by the viewing user who has selected the coin-throwing effect image 69 but also by other viewing users who are viewing the competition singing.

Note that the coin-throwing effect function according to the embodiment can be performed on a singing video in which a song is being performed, and after performing the coin-throwing input, the coin-throwing effect image 69 is superimposed on the singing video almost without delay. . That is, in the example of FIG. 10, the viewing user can superimpose the coin-throwing effect image 69 on the first singing video 60A. Image 69 cannot be superimposed. More specifically, even if the viewing user long-presses the operation icon 58D corresponding to the singing video that the singing user is not singing, the coin-throwing effect function does not accept the long-press.

Further, when receiving an instruction to superimpose the coin effect image 69, the evaluation function receives an input of a score corresponding to the coin effect image 69 as an evaluation (hereinafter referred to as "score evaluation"). In the service of the embodiment, as an example, points corresponding to the coin-throwing effect image are input as points for score evaluation.

The score evaluation by the second evaluation action is input by the viewing user performing the second evaluation operation (tapping) on the coin-throwing effect image 69 . The evaluation function receives an input of a score corresponding to the coin effect image 69, and derives the total score (hereinafter referred to as "total evaluation score") input during distribution of the singing video as an evaluation result. The total evaluation score is the sum of the scores input (given) by the plurality of viewing users through the second evaluation actions. Then, the evaluation function determines the winner of the competition singing competition based on the evaluation total score derived based on the scores input until the competition singing competition ends. That is, the singing user of the singing video with a relatively high total evaluation score is the winner. Thus, according to the service of the embodiment, a plurality of viewing users win the singing user who supports themselves by performing the second evaluation behavior in cooperation with the singing user who supports them (singing video). , the audience user can easily empathize with the singing user.

In this manner, the evaluation function according to the embodiment can prompt the viewing user to input a coin by accepting an input of points as an evaluation in response to an instruction to superimpose the coin effect image 69 . Note that there is no upper limit to the number of times each viewing user can input coins. In other words, the viewing user can increase the evaluation total score of the singing video that he/she sympathizes with by tapping the coin-throwing effect image 69 many times.

(3) Adjustment of Total Evaluation Score Furthermore, in the service of the present embodiment, the total evaluation score is adjusted according to the number of accounts of the viewing users who have input the coins. Specifically, the evaluation total score is adjusted according to the formula shown in [Formula 5]. Due to this feature, in the service of the present embodiment, the total score, which is a simple accumulated value of points input by point evaluation, may not match the total evaluation score. In other words, even if the total score is inferior, the evaluation total score can be reversed depending on the number of accounts of the viewing users who input the coins.

[Number 5]
Evaluation total score = Cumulative score x {1 + (weight w5 x number of accounts)}
(However, w5 = 5/10000)

(4) Display of high-evaluation users Furthermore, viewing users who have performed score evaluations (second evaluation actions) that are relatively higher than other viewing users for singing videos, that is, viewing users with a large accumulated score input (Hereinafter referred to as "highly rated user"), an image (icon image 64) is displayed on the screen 3a of the mobile terminal 3B. As a result, the viewing user can make other viewing users recognize the singing user that he/she supports. Also, the viewing user can make the singing user recognize that he or she is cheering for the song.

In addition, in the evaluation function according to the embodiment, the top three users with the highest number of input points are regarded as highly evaluated users, and the icon images 64 of the highly evaluated users are displayed on the screen 3a for each singing video, but the icon images 64 are displayed. The number of highly rated users is not limited to this.

[2-2-6-4. Other features]
The server 4 may store information for each singing user (hereinafter referred to as “singing user information”) in the HDD 26 . The singing user information includes the number of fans that the singing user has, the singing user's past competition record and winning percentage, and favorite songs. Then, the competition singing function may receive a competition request from the first singing user who has about the same number of fans to the second singing user. It is conceivable that the number of fans that a singing user has varies depending on the singing ability of the singing user. In this way, by making it a condition for accepting competition singing that the number of fans is about the same, it is possible to prevent competition singing between singing users with greatly different singing abilities from being performed.

More specifically, when the first singing user makes a competition request to the second singing user, the competition singing function compares the number of fans of the first singing user and the number of fans of the second singing user, and the number of fans is within a predetermined reference value (for example, within ±20%), a match request from the first singing user to the second singing user is accepted. In addition, the number of fans increases when the viewing user registers himself/herself as a fan of the singing user through the video posting viewing application. There is no limit to the number of singing users that can be registered as fans by viewing users.

In addition, the competition singing function may accept a competition request even if the number of fans is the same as long as other conditions are satisfied, or if the second singing user approves even if the number of fans is not the same. A battle request may be accepted. On the other hand, the competition singing function may accept only competition requests with approximately the same number of fans. Here, "only" means, for example, that even if other conditions are satisfied, a battle request with a different number of fans will not be accepted.

Also, the competition singing function may give the singing user a consideration according to the evaluation total score obtained by the singing user who won the competition singing by the evaluation action for himself. The consideration here is money, or points that can be used in a video posting viewing application (video posting site) or other online services. In addition, the singing user who won the competition singing may obtain a consideration according to the score obtained by summing not only the total evaluation score of himself but also the total evaluation score of the opponent (so-called total collection).

Therefore, the server 4 (evaluation function) according to the present embodiment can prevent an excessive influence that the coin input by some viewing users may have on the total evaluation score.

[3. Modification]
[3-1. Modification 1 (Modification regarding calculation of total evaluation score)]
In the above-described embodiment, the tallying unit 82 tallies the points input by inputting coins (score evaluation) for a specific singing video to obtain a total score. On the other hand, the tallying unit 82 may add the impression evaluation to obtain the cumulative score. For example, the tallying unit 82 may calculate the total score by adding the number of impression evaluation acquisitions to the total score input by coin input (score evaluation). It should be noted that the cumulative score may be obtained by adding a value obtained by multiplying the number of obtained impression evaluations by an appropriate coefficient to the above total value. The coefficient by which the number of impression evaluation acquisitions is multiplied functions as the weight of the impression evaluation with respect to the total evaluation score. The coefficient can be set arbitrarily. The coefficient may be, for example, a positive real number less than one.

[3-2. Modified Example 2 (Modified Example Concerning Identification of Real Numbers)]
(1) Example of Identifying the Number of Terminals In the above-described embodiment, the identification unit 83 identifies the number of accounts of viewing users who have input money as a real number of viewing users who have input money to a specific singing video. On the other hand, the specifying unit 83 may specify the number of terminals used for coin input or an approximate value thereof. As a result, it is possible to prevent an excessive impact on the evaluation total score due to improper coin input from multiple accounts by some viewing users.

The number of terminals used for inputting coins or an approximate value thereof is obtained by eliminating duplicates of the mobile terminals 3B from the number of accounts for which inputting has been performed. Duplication of the mobile terminal 3B can be determined with a certain degree of accuracy by comparing session identification information, IP addresses, and the like. For example, when a single mobile terminal 3B is used to input coins from a plurality of accounts, there is a possibility that the session identification information and IP address (here, the IP address of the mobile terminal 3B) are the same.

(2) Example of Identifying Actual Number of People In the above-described embodiment, the identifying unit 83 identifies the number of accounts of viewing users who have input money as the actual number of viewing users who have input money to a specific singing video. On the other hand, the specifying unit 83 may specify the actual number of viewing users who have input coins or an approximate value thereof. As a result, it is possible to prevent an excessive impact on the evaluation total score due to improper coin input from multiple accounts by some viewing users.

The actual number of viewing users who have input money or an approximate value thereof can be obtained by excluding overlapping viewing users from the number of accounts for which input has been made. Duplication of viewing users is caused by the e-mail address registered in the account, the identification information of the payment method used when obtaining the coin effect image (for example, credit card number, bank account number, electronic wallet identification information, Identification information of the virtual account), IP address, etc. can be compared with a certain degree of accuracy. For example, when a plurality of mobile terminals 3B are used to input coins from a plurality of accounts, the session identification information may be different and the IP address (here, the IP address of the router) may be the same.

[3-3. Modification 3 (modification regarding screen display)]
In the above embodiment, the moving image evaluation unit 73 counts the number of impression evaluation acquisitions, and the moving image distribution unit 75 updates the display of the impression evaluation progress image 66 . Therefore, the impression evaluation progress image 66 represents the provisional number of viewers who have evaluated the impression of the singing video being distributed. In response to this, the moving image evaluation unit 73 aggregates the provisional evaluation total score, and the moving image distribution unit 75 updates the display of the numerical value or the image representing the provisional evaluation total score instead of or together with the impression evaluation progress image 66. You may This makes it easier for the viewing user to grasp the situation including the superiority or inferiority of the singing video related to the battle singing video that the viewing user is viewing.
