The process is executed, and one piece of music to be recommended is extracted as a reference music.

  For example, it is assumed that the user X and the user Y who perform the karaoke game are logged in, and the user X and the user Y have the user-by-user scoring history information illustrated in FIG. 5A.

  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 an average value (i.e., 82 points) of the music piece "aab" as a 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, in the user-specific scoring history information of the user X and the user Y, there is no music in common, and therefore the recommendation processing unit 230 determines the average value of the music “aac” and “bbj” for which all user average points 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. The recommended music extraction process is executed based on the corrected reference music average point.

  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 140 or the display unit 140 of the remote control device (not shown).

  For example, as shown in FIG. 6, in the case where the reference music average point is "82 points", the recommendation processing unit 230 determines that "all people's average points are 3 or less within the upper and lower three points from 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. It may be displayed on unit or display unit 140, or a display unit of a remote control device (not shown) that can be selected as a recommended music to be selected as a recommended music as music selected at random or extracted 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 the attributes included in the user information such as the gender and age of the user to be recommended, or
(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.

  In addition, the recommendation processing unit 230 further extracts music that matches the singing tendency of the user to be recommended instead of or in addition to (1) to (4) above. 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 Music of the singer being extracted as music conforming to 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) A reference music piece for determining whether or not a predetermined comparison condition is satisfied in the average value of “one-round scoring result”) and the reference music average point is corrected when the comparison condition is satisfied. 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 correction processing table data from the management server device 30 illustrated in FIG. 4.

  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 point is corrected in the positive direction (that is, a value described later is added to the reference music average point) 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. Calculation (that is, subtracting a value to be described later from the reference music average point) is performed.

  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. Furthermore, “α” is a correction coefficient that is 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 ( Perform addition).

  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). "82 points", the average value T during the karaoke game is "71 points" and the correction coefficient α is "0.3", and the calculation (addition) of the above equation 1 is performed, and a new reference music average point 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 result may be excluded and the above-mentioned reference music average point correction process may be executed.

  Furthermore, the recommendation processing unit 230 corrects the reference music average point when the average value during the login match or the average value during the karaoke match is compared with the reference music average point and exceeds a predetermined range. If the score of each logged-in user in the past or during a karaoke match is compared with the reference music average point and exceeds a predetermined range of any one user, the reference music average point is corrected 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 scoring information of music data to be selected and user information of a singing user who sings.

  Further, in this operation, it is assumed that the login user who has logged in to the karaoke service via the karaoke system 10 executes processing for identifying the number of users participating in the karaoke competition mode.

  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, upon receiving an instruction to start a battle mode for a karaoke game (step S101), the karaoke game management unit 220 determines whether all users participating in the game 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 first user is the login user, the normal selection process is performed to allow the first user to freely select the first reference song (step S110), and the process proceeds to step S111. To do.

  The karaoke match management unit 220 is processing for receiving the input of the music selection number as selection processing, and may directly receive the music selection number, or provides the music list to a remote control device (not shown) to select the music. The song selection number may be accepted by causing the user to make the selection.

  Next, when it is determined that all the users participating in the battle mode are logged-in users, the recommendation processing unit 230 extracts reference music that specifies a reference music that is the first music to be recommended to the first user A process is performed (step S103).

  Specifically, as described above, based on the user ID of each logged-in user, the recommendation processing unit 230 uses the database 300 to sing song data sung in the past for the logged-in user and its scoring result (all user refund points Identification and identification of a first music piece serving as a reference when performing a karaoke song in a competition format based on the specified music data and its scoring result, and to the first user of the specified first music piece. Perform the recommendation of

  In addition, when the reference processing music is specified, the recommendation processing section 230 displays the information on the display section or the display section 140 of the remote control device (not shown), waits for the 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 match management unit 220 determines whether the recommendation processing unit 230 can not specify the reference music, and detects the user's operation when the reference music is specified. In step S104, it is determined whether the reference music specified by the above is selected or rejected.

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

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

  The end of reproduction of the music data includes not only that the music data has been reproduced to the end, but also the case where the music data is forcibly ended halfway. However, in this operation, it is assumed that the reproduction termination of the music data excludes the condition that can not be scored, such as termination in a silent state or within a certain playback time, and the reproduction is completely terminated in the marking possible state.

  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. Based on the scoring result based on the calculation, 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 S113).

  Then, the recommendation processing unit 230 acquires all user average points of the reference music from the scoring history DB 303 via the management server device 30, and based on the acquired all user average points (that is, reference music average points), 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, as the recommended music, music having all user average points belonging to a predetermined range (within ± 3 points) from all user average points of the reference music.

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

  Next, the karaoke match management unit 220 detects whether the recommended music has been selected by detecting the user's input operation of the music selection number, and starts reproduction of the corresponding music data based on the information and the music selection number. An instruction to start reproduction is output, and the rating execution unit 210 waits for the end of reproduction of music data (step S116).

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

  The end of reproduction of the music data includes not only that the music data has been reproduced to the end, but also the case where the music data is forcibly ended halfway. However, in this operation, it is assumed that the reproduction termination of the music data excludes the condition that can not be scored, such as termination in a silent state or within a certain playback time, and the reproduction is completely terminated in the marking possible state.

  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 match 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. If it is determined, the process proceeds to 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 match management unit 220 determines that the instruction to end the karaoke match mode is not detected, the recommendation processing unit 230 determines whether the comparison condition for correcting the reference music average point is satisfied. Whether or not there is a divergence between the scoring result of each user participating in the karaoke game during the karaoke game and the reference music average point is determined (step S121).

  Then, when it is determined that the comparison processing for correcting the reference music average point is satisfied, the recommendation processing unit 230 executes the above-described reference music average point 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 ended.

  In addition to the user's end instruction, the end instruction of the karaoke battle mode in step S120 also includes an instruction from the control unit 180 when, for example, singing of a predetermined number of pieces of music is ended.

  As described above, in the karaoke communication system 1 according to the present embodiment, for example, a song having an average score similar to the average score of all users of the first song during the karaoke game, based on the first song. Since it is possible to recommend a song that another user sings as the second user, it is possible to recommend a song having uniformity in the singing level.

  Therefore, in the karaoke communication system 1 according to the present embodiment, even if the user sings different songs by scoring based on the songs having a uniform song level, the scoring results will be 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 participating in the karaoke match is a login user, when the past singing history of the participating user can be used, Also for the reference song, which is the first song of the karaoke match, it is possible to recommend a song taking into consideration 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. Can be corrected as appropriate, so it is possible to bias the music that is difficult for each user participating in the karaoke match, or even if there is a difference in singing levels for each user Can recommend a song with a high score.
