  On the other hand, when there is no common music in the music data sung in the past by the logged-in user, the recommendation processing unit 230 has a predetermined condition (specifically, the average score of all users matches). Is set as the reference music average point. Note that when a plurality of reference music average points are set, the recommendation processing unit 230 identifies one reference music average point from among them, and sets the maximum all-user average point among them as the reference music average point To do.

  Then, the recommendation processing unit 230 executes a reference song average point correction process described later based on the set reference song average score and the score result of the reference song for all the logged-in users, and a recommended song extraction described later. The process is executed, and one piece of music to be recommended is extracted as a reference music.

  For example, it is assumed that a karaoke match is performed between the user X and the user Y who are logged in, and the user X and the user Y have the user-specific scoring history information shown in FIG.

  In this case, the music “aab” is common in the user-specific scoring history information of the user X and the user Y. Therefore, the recommendation processing unit 230 sets the average value of the music “aab” (that is, 82 points) as the reference music average point.

  On the other hand, for example, it is assumed that a karaoke match is performed between the user X and the user Y who are logged in, and the user X and the user Y have the scoring history information for each user shown in FIG.

  In this case, since there is no common music in the user-specific scoring history information of the user X and the user Y, the recommendation processing unit 230 determines the average value of the music “aac” and “bbj” in which the average scores of all users match ( That is, 84 points) are set as the reference music average points.

  And the recommendation process part 230 performs the reference | standard music average score correction | amendment process mentioned later based on the set reference | standard music average point (82 or 84 points) and the scoring result of the said reference music in all the login users. On the other hand, a recommended music extraction process described later is executed to extract one music to be recommended as a reference music.

  When the recommendation processing unit 230 extracts one piece of music to be recommended as the reference music, the recommendation processing unit 230 obtains information on the extracted music from the recording unit 160 or the management server device 30 and displays the display unit of a remote control device (not shown). Alternatively, it is displayed on the display unit 140.

  Further, the recommendation processing unit 230 specifies the music selected by the first user as the reference music.

  In addition, when all the users participating in the karaoke match are not logged-in users, or for music recommended as music, the recommendation processing unit 230 uses the music selected by the user who sings first in the karaoke match as a reference. Specify (confirm) the song. However, even if a song other than the reference song recommended by the user who sings first in the karaoke match is selected, the recommendation processing unit 230 determines the selected song as the reference song.

[4.2] Recommended Music Extraction Processing Next, details of recommended music extraction processing executed in the recommendation processing unit 230 of the karaoke system 10 of the present embodiment will be described.

  The recommendation processing unit 230 performs a reference song average point in the reference song (reference song extracted in the recommended song extraction process during the reference song extraction process) specified by the reference song extraction process or a reference song average point correction process described later. Based on the corrected reference music average point, the recommended music extraction process is executed.

  In particular, as the recommended song extraction process, a song having an average score of all users (all users registered in the user information DB 302) belonging to a predetermined range (for example, ± 3 points) from the reference song average score is selected as a recommended song. And the result is displayed on the display unit or display unit 140 of the remote control device (not shown).

  For example, as shown in FIG. 6, when the reference music average score is “82 points”, the recommendation processing unit 230 determines that “Minori no Kuma-san” has all user average scores within 3 points above and below the “82 points”. ”,“ Beetle ”,“ 00 ”, and“ ΔΔΔΔ ”are extracted as recommended songs.

  When the recommended processing unit 230 extracts a large number of music pieces as the recommended music piece extraction process, basically, all the extracted music pieces can be selected as recommended music pieces by a corresponding user. Display unit 140 or a display unit 140, or a display unit of a remote control device (not shown) that can be selected as a recommended music by selecting a music selected at random or selected as described later. Or you may display on the display part 140. FIG.

  In addition, when a plurality of recommended songs are extracted, the recommendation processing unit 230 is a method of narrowing down to the number of recommended songs of one or less recommended history of user information of users to be recommended from the extracted recommended songs. Based on information, attribute information such as age and gender of the user, or user preference information such as a favorite artist or favorite song, the music may be further extracted and the extracted music may be recommended as a recommended music .

For example, the recommendation processing unit 230
(1) Music included in the singing history in the user information of the user to be recommended (2) Music registered as a favorite in the user information of the user to be recommended or an artist registered as a favorite artist,
(3) Music that is specified as popular (such as the top 50 songs) in attributes included in user information such as the gender and age of the user to be recommended
(4) Music that matches two or more of (1) to (3) may be further extracted, and the extracted music may be recommended as recommended music.

  Further, the recommendation processing unit 230 further extracts music that matches the singing tendency of the user to be recommended instead of (1) to (4) above or in addition to (1) to (4). You may recommend the extracted music as a recommendation music.

  Specifically, the recommendation processing unit 230, in extracting recommended music based on singing tendency, associates with each user (for example, all users registered in the user information), and sings in the singing history of singing in the past. Include singer names based on frequency and use clustered two-dimensional or three-dimensional space (spatial coordinates), and based on the singing frequency in the user's singing history, included in the spatial range according to the singing frequency Singer's music is extracted as music that matches the singing tendency.

  The recommendation processing unit 230, for details of the technique of extracting recommended music based on the singing tendency, uses the technique described in Japanese Patent Application Laid-Open No. 2012-63458 and matches the singing tendency of the user. Is recommended as a recommended song.

[4.3] Reference Music Average Score Correction Processing Next, details of the reference music average score correction processing executed in the recommendation processing unit 230 of the karaoke system 10 of the present embodiment will be described.

  In the reference music extraction process, the recommendation processing unit 230 calculates the reference music average score of the reference music, and the average value of the scoring results of the reference music of all the logged-in users (hereinafter referred to as “past scoring results”). It is determined whether or not a predetermined comparison condition is satisfied, and if the comparison condition is satisfied, a reference music average point correction process for correcting the reference music average point is executed.

  In addition, as a process executed during the karaoke match for the second and subsequent songs, the recommendation processing unit 230 performs the singing order once in the karaoke match, and the reference song average point at that time and the karaoke match during the karaoke match The average value of the scoring results (hereinafter referred to as “all scoring results”) of all users who have participated in the previous karaoke battle, or the scoring results of all users (2nd or 3rd round) , “Circular scoring result”) and whether or not a predetermined comparison condition is satisfied, and if the comparison condition is satisfied, the reference music for correcting the reference music average score The average point correction process is executed.

  In particular, the recommendation processing unit 230 performs an average value based on the total number of logged-in users in the past scoring results (hereinafter referred to as “logged-in user average value”) or karaoke in the standard music extraction process with respect to the standard music average score. In the reference music average score correction process during the battle, an average value based on the users who are in the karaoke battle of all the scoring results or the round scoring results (hereinafter also referred to as “average value during the karaoke battle”) is determined in advance. When the range (for example, 10 points) is exceeded, it is determined that the comparison condition is satisfied.

  Specifically, the recommendation processing unit 230 uses the correction processing table data from the management server device 30 illustrated in FIG.

  In addition, the recommendation processing unit 230 calculates a login user average value in the reference song extraction process, or calculates an average value during the karaoke match in the reference song average point correction process during the karaoke match.

  Then, the recommendation processing unit 230 compares the average value of the logged-in user or the average value during the karaoke match with the reference music average score, and exceeds a predetermined range (± 10 points) (for example, ± 10.1). When the score is equal to or higher than the score), a calculation for correcting the reference music average score is executed.

  As this calculation, the recommendation processing unit 230 is a case where the average value of the logged-in user or the average value during the karaoke match is smaller than the reference song average score, and exceeds the predetermined range (−10 points) ( For example, in the case of -10.1 points or less), the reference music average score is corrected in the plus direction (that is, a value described later is added to the reference music average score), and the login user average value is higher than the reference music average score. Or, if the average value during a karaoke match is large and exceeds a predetermined range (+10 points) (for example, if it is +10.1 points or more), the reference song average point is corrected in the negative direction. (I.e., subtracting a value to be described later from the reference music average point).

  Then, the recommendation processing unit 230 calculates the current reference music average point S (N) as a new reference music average point S (N + 1) based on the following (Equation 1). Is executed to correct the reference music piece average point.

  In (Expression 1), “T” indicates the average login user value based on the total number of logged-in users in the past scoring results in the reference music extraction process, and in the reference music average score correction process during a karaoke match, The average value during the karaoke battle of all scoring results or one round scoring results at that time is shown. Further, “α” is a correction coefficient determined based on the current reference music average point in the correction processing table data.

  For example, it is assumed that the reference song is “Kuma no Mori”, the reference song average score is “82 points”, and “user X” and “user Y” are participating in the karaoke match.

  In this case, “user X” in the battle (for example, the third round) scored “70 points” for the recommended song “beetle beetle” and “user Y” scored “72 points for the recommended song“ ΔΔΔ ”. The average value during the karaoke match is “71 points”, which is 10.1 or more points different from the reference song average score “82 points”. Therefore, the recommendation processing unit 230 performs the reference song average score correction process ( Add).

  The recommendation processing unit 230 obtains the correction coefficient “0.3” by referring to the correction processing table data because the reference music average score is “82”, and the reference music average score S (N). Is “82 points”, the average value T during the karaoke match is “71 points”, and the correction coefficient α is “0.3”, the calculation (addition) of the above (Equation 1) is performed, and a new reference song average score is obtained. S (N + 1) is set to “85.3 points”.

  The recommendation processing unit 230 executes the above-described reference music extraction process or recommended music extraction process based on the set new reference music average point.

  In addition, when there is a user who sang using a song other than the song recommended by the recommended song extraction process during the karaoke match, the recommendation processing unit 230 uses the scoring result of the user to perform the above reference song. The average point correction process may be executed, or the reference music average point correction process may be executed by excluding the result.

  Further, the recommendation processing unit 230 compares the average value of the logged-in user or the average value during the karaoke match with the reference music average score, and corrects the reference music average score when a predetermined range is exceeded. If each of the logged-in user's past or karaoke match score results is compared with the reference song average score, the reference song average score is corrected when it exceeds the predetermined range for any one user May be.

[5] Karaoke Battle Processing Next, a recommendation information providing process during a karaoke battle executed in the karaoke system 10 of the present embodiment will be described with reference to FIGS. 7 and 8. 7 and 8 are flowcharts showing the operation of the recommendation information providing process during the karaoke battle that is executed in the management server device 30 of the present embodiment.

  In this operation, it is assumed that the DB 300 of the management server device 30 has already recorded the scoring information of the music data to be selected and the user information of the singing user who sings.

  Moreover, in this operation | movement, the number-of-users identification process of the user who participates in karaoke battle | competition mode shall be performed by the login user who is logging in to the karaoke service via the karaoke system 10.

  Furthermore, in this operation, scoring results when singing music other than music recommended by the recommended music extraction process are excluded from the standard music average score correction process, and included in the total result of the karaoke match. .

  First, when receiving an instruction to start a battle mode for karaoke battles (Step S101), the karaoke battle management unit 220 determines whether or not all users participating in the battle mode are login users (Step S102). .

  At this time, if it is determined that all users participating in the karaoke battle mode are logged-in users, the karaoke battle management unit 220 proceeds to the process of step S103 and all participating in the karaoke battle mode. If it is determined that the user is a logged-in user, a normal selection process is performed to allow the first user to freely select the reference music that is the first music (step S110), and the process proceeds to step S111. To do.

  Note that the karaoke match management unit 220 is a process for accepting an input of a music selection number as a selection process, and may accept a music selection number directly or provide a music list to a remote control device (not shown) to select a music piece. The music selection number may be accepted.

  Next, when it is determined that all users participating in the battle mode are login users, the recommendation processing unit 230 extracts a reference song that specifies the reference song that is the first song to be recommended to the first user. Processing is executed (step S103).

  Specifically, as described above, the recommendation processing unit 230, based on the user ID of each logged-in user, from the database 300 the song data sung in the past for the logged-in user and the scoring result (all user refund points are calculated). To the first user of the specified first music and the specified first music as a reference when performing a battle-type karaoke song based on the specified music data and the scoring result Make recommendations.

  Note that when the reference music is specified, the recommendation processing unit 230 displays the information on the display unit or the display unit 140 of the remote controller (not shown), waits for a user's selection input, and specifies the reference music. If not, the information is displayed on the display unit or display unit 140 of the remote control device (not shown).

  Next, the karaoke battle management unit 220 determines whether or not the reference music piece could not be specified by the recommendation processing unit 230, and detects the user's operation when the reference music piece is specified. In step S104, it is determined whether the reference music specified by the above is selected or rejected.

  At this time, if the specified reference song is selected, the process proceeds to step S111. If it is determined that the specified reference song is not selected, step S111 is performed via the normal selection process of step S110. Move on to processing.

  Next, the karaoke battle management unit 220 outputs a playback start instruction to start playback of music data based on the music selection number to the control unit 180 while specifying the selected music as a reference music, and a scoring execution unit 210 waits for the end of reproduction of the music data (step S111).

  Note that the end of reproduction of the music data includes not only that the music data has been reproduced to the end, but also a case where the music data is forcibly terminated. However, in this operation, it is assumed that the reproduction of the music data has been completed in a scorable state, excluding conditions that cannot be scored such as a silent state or completion within a certain reproduction time.

  Next, when the scoring execution unit 210 detects the end of reproduction of the music data (step S112), the scoring execution management unit 220 sings the scoring execution unit 210 while performing a singing user specifying process for specifying the user who sang. The scoring result is calculated, and the scoring result information is registered in the recording unit 160 and is also registered in the scoring history DB 303 via the management server device 30 (step S113).

  Next, the recommendation processing unit 230 acquires the average user average score of the reference music from the scoring history DB 303 via the management server device 30, and based on the acquired average user average score (that is, the reference music average score) or Based on the corrected reference song average score, the recommended song extraction process is executed (step S114).

  In particular, as the recommended music extraction process, the recommendation processing unit 230 extracts music having an average score of all users belonging to a predetermined range (within ± 3 points) from the average score of all users of the reference music as a recommended music.

  Next, the recommendation processing unit 230 displays the extracted one or more music pieces as recommended music pieces on the display unit or the display unit 140 of the remote controller (not shown), and waits for an operation input of a music selection number (step S115).

  Next, the karaoke match management unit 220 determines whether or not a recommended song has been selected by detecting a user's operation for inputting a song selection number, and starts reproduction of the corresponding song data based on the information and the song selection number. The reproduction start instruction is output, and the scoring execution unit 210 is made to wait for the completion of reproduction of the music data (step S116).

  Specifically, when the recommended music is selected, the karaoke battle management unit 220 outputs a reproduction start instruction to start reproduction of the corresponding music data based on the fact and the music selection number, and the recommended music is If not selected, a reproduction start instruction for starting reproduction of the corresponding music data is output based on the fact and the music selection number.

  Note that the end of reproduction of the music data includes not only that the music data has been reproduced to the end, but also a case where the music data is forcibly terminated in the middle, as described above. However, in this operation, it is assumed that the reproduction of the music data has been completed in a scorable state, excluding conditions that cannot be scored such as a silent state or completion within a certain reproduction time.

  Next, when the scoring execution unit 210 in the karaoke battle management unit 220 detects the end of reproduction of the music data (step S117), the scoring execution unit 210 performs the singing user specifying process for specifying the user who sang, based on the singing. The scoring result is calculated, and the scoring result information is registered in the recording unit 160 and is registered in the scoring history DB 303 via the management server device 30 (step S118).

  In the case of a song other than the recommended song, the karaoke battle management unit 220 registers flag information indicating that in the recording unit 160 in accordance with the scoring result.

  Next, the karaoke battle management unit 220 executes a singing user specifying process for specifying the singing user to determine whether or not the singing user is in the last order (step S119), and is not the singing user in the last order. When it determines, it transfers to the process of step S114.

  On the other hand, if the karaoke battle management unit 220 determines that the singing user is the last singing user by executing the singing user specifying process for specifying the user who sang, it has detected whether or not the karaoke battle mode end instruction has been detected. Is determined (step S120).

  At this time, if the karaoke battle management unit 220 determines that an instruction to end the karaoke battle mode has not been detected, whether or not the recommendation processing unit 230 has a comparison condition for correcting the reference music average point is determined. (Whether there is a divergence between the scoring result during the karaoke match and the reference music average score of each user participating during the karaoke match) (step S121).

  If the recommendation processing unit 230 determines that the comparison condition for correcting the reference music average score is satisfied, the recommendation processing unit 230 executes the above-mentioned reference music average score correction processing (step S122) and proceeds to the processing of step S114. If it is determined that the comparison condition is not satisfied, the process directly proceeds to step S114.

  On the other hand, if the karaoke battle management unit 220 determines that an instruction to end the karaoke battle mode has been detected, the karaoke battle management unit 220 executes a battle karaoke mode end process such as summarizing the scores and displaying the battle results on the display unit 140. (Step S123), this operation is terminated.

  Note that the instruction to end the karaoke battle mode in step S120 includes an instruction from the control unit 180 such as when the singing of a predetermined number of songs is ended in addition to the user's instruction to end.

  As described above, in the karaoke communication system 1 according to the present embodiment, during the karaoke battle, for example, a music having an average score similar to the average score of all users of the first music is used as a reference. Since the music sung by other users can be recommended as the second user, it is possible to recommend music having a uniform singing level.

  Therefore, in the communication system 1 for karaoke of this embodiment, even if it is a case where a user sings a different music piece by scoring based on the music which has the uniformity in a singing level, about those scoring results, Since the difference in the user's singing level can be appropriately reflected, when the karaoke singing is achieved by the battle format of a plurality of users, it is possible to compete fairly in the scoring result based on the singing result.

  Moreover, in the communication system 1 for karaoke of this embodiment, when the user who has participated in the karaoke battle can use the past singing history of the participating user, such as a login user, As for the reference music that is the first song of the karaoke match, it is possible to recommend a song that takes into account the singing level of the participating users.

  In the karaoke communication system 1 of the present embodiment, when the reference music is different from the singing level of the user participating in the karaoke battle, when recommending the music to each user as described above. The average score of the music can be corrected as appropriate, so that even if there is a difference in the singing level among the users, the users tend to be difficult to play for each user participating in the karaoke match, or Can recommend high-quality music.
