  As shown in FIG. 5, the user unit classification database 3073 stores user unit classification information in which user IDs of a plurality of users are associated with unit IDs that are unit identification information of a plurality of units having different preferences. Has been.

  The unit ID corresponding to each user represents the unit classification of the preference of each user. In particular, the unit ID associated with the user ID of each user in the user unit classification information is a unit corresponding to the preference of each user (corresponding to the first unit described in each claim. Is a unit ID (corresponding to the first unit identification information described in each claim. Hereinafter, it is appropriately referred to as “first unit ID”).

  Here, in general, the consumption behavior of a user who is a consumer often reflects his / her own age and preferences. For example, the content of the product purchased by the user, that is, the name and type of the product, and the user's preference are closely related. The product includes performance music data in karaoke. Therefore, the same applies to the case where the user receives a performance music reproduction service using performance music data, and the content of the user's music selection operation and the user's preference are closely related.

  In the present embodiment, the user unit classification information associated with a plurality of user IDs and a plurality of unit IDs stored in the user unit classification database 3073 based on the above correspondence is the singing history database 3071. Are generated based on the plurality of users' singing history information corresponding to the music selection operations of the plurality of users stored in. In the present embodiment, the control unit 301 of the host server 300 executes processing related to generation of user unit classification information at an appropriate interval, for example, at an interval of once / month. Thereby, the user unit classification information stored in the user unit classification database 3073 is generated (updated). In the process related to the generation of the user unit classification information, the control unit 301 associates the user ID of each user with the user ID from among the plurality of unit IDs based on the song history information of the plurality of users stored in the singing history database 3071. Each unit ID is determined. Then, the user unit classification database 3073 is accessed, and the user unit classification information based on the determination result is stored.

  In this example, unit IDs associated with the user IDs of the plurality of users are determined based on the singing history information of the plurality of users, and user unit classification information based on the determination results is stored in the user unit classification database 3073. However, it is not limited to this. For example, based on purchase history information of a plurality of users in Electronic Commerce (EC), unit IDs corresponding to the user IDs of the plurality of users are determined, and user unit classification information based on the determination results is determined as a user unit classification. You may make it memorize | store in the database 3073. FIG.

  FIG. 6 shows an example of the contents stored in the unit-specific correlation value database 3074.

  As shown in FIG. 6, the correlation value database 3074 for each unit has a correlation calculated in advance by the control unit 301 of the host server 300 in accordance with a combination of two units represented by two assumed unit IDs. The value is stored.

  The correlation value represents the presence / absence of a contact point of preference corresponding to each of the two units represented by the two unit IDs, that is, the degree of similarity between the two units. Therefore, when the preference corresponding to each of the two units is the same, that is, when the two units are the same, the corresponding correlation value is “1” which is the maximum value. And the more the contact point of preference corresponding to each of the two units, that is, the stronger the similar correlation between the two units, the larger the corresponding correlation value (the correlation value becomes closer to “1”), and conversely, The smaller the number of preference contacts corresponding to each of the two units, that is, the weaker the similar correlation between the two units, the smaller the corresponding correlation value (the correlation value becomes closer to “0”). The details of the processing relating to the calculation of the correlation value will be described later.

  In the example illustrated in FIG. 6, for example, the correlation value of the unit represented by the unit ID “1” with respect to the unit represented by the unit ID “1” is “1” and the unit represented by the unit ID “2”. The correlation value is “0.820342”, the correlation value of the unit represented by the unit ID “3” is “0.841667”, the correlation value of the unit represented by the unit ID “4” is “0.786672”, .. calculated and stored as Hereinafter, although explanation is omitted, the corresponding correlation values are calculated and stored in the same manner for combinations other than those described above.

  FIG. 7 shows an example of the contents stored in the unit-specific advertisement database 3075.

  As illustrated in FIG. 7, the advertisement database 3075 for each unit stores advertisement classification information in which unit IDs of a plurality of units are associated with advertisement IDs that are advertisement identification information of the plurality of advertisement information. In this advertisement classification information, for each unit ID of each unit, there is an advertisement ID of advertisement information predetermined as advertisement information suitable for users belonging to the unit (for example, advertisement information corresponding to the user's preference). Each is associated.

  A feature of the present embodiment having the above-described configuration is that a plurality of first unit IDs corresponding to a plurality of users are acquired, and a plurality of first units represented by the acquired plurality of first unit IDs. , A unit ID (corresponding to second unit identification information described in each claim) representing a unit (corresponding to a second unit described in each claim, hereinafter referred to as “second unit” as appropriate) having a predetermined similar correlation. (Hereinafter, referred to as “second unit ID” as appropriate) for each first unit, the plurality of first unit IDs obtained and the plurality of second units respectively determined for each first unit. The advertisement information to be advertised is determined based on the unit ID, and the determined advertisement information to be advertised is read from the mass storage device 307.

  That is, in general, even if the user is not an advertisement directly related to his / her preference, the user is slightly interested in an advertisement having a taste relatively close to his / her preference or a product corresponding to such an advertisement. Can also accept. Therefore, in the present embodiment, corresponding to this, after obtaining the first unit ID related to the first unit corresponding to the preference of each user, the preference of each user is relatively compared for each first unit. A second unit corresponding to a close preference, that is, having a predetermined similar correlation is specified, and a second unit ID representing the second unit is determined. Then, advertisement information to be advertised is determined based on each first unit ID corresponding to each user and each determined second unit ID, and the advertisement information to be advertised is stored in a large capacity Read from device 307. By doing in this way, in addition to the advertising information directly linked to the preferences of each user, it is possible to provide each user with advertising information with a preference that is relatively close to the preference of each user. Details of these will be described below.

  A control procedure related to calculation of the correlation value executed by the control unit 301 of the host server 300 will be described with reference to FIG.

  In FIG. 8, this process is started when, for example, the user of the host server 300 executes an appropriate operation.

  First, in step SS10, the control unit 301 sets the value of the variable A corresponding to one of the plurality of unit IDs to 1. For example, A = 1 corresponds to the unit ID “1”, A = 2 corresponds to the unit ID “2”, A = 3 corresponds to the unit ID “3”,.

  Thereafter, in step SS20, the control unit 301 associates, for example, unit IDs of a plurality of units stored in the database storage area of the mass storage device 307 with representative vectors representing preferences corresponding to the units. The stored representative vector database for each unit (not shown) is accessed. And the representative vector matched with unit ID corresponding to the value of the variable A at this time is acquired. Then, let x be the value of the acquired representative vector.

  Then, the process proceeds to step SS30, and the control unit 301 sets the value of the variable B corresponding to any of the plurality of unit IDs to 1. For example, B = 1 corresponds to the unit ID “1”, B = 2 corresponds to the unit ID “2”, B = 3 corresponds to the unit ID “3”,.

  Thereafter, in step SS40, the control unit 301 accesses the unit-specific representative vector database, and acquires a representative vector associated with the unit ID corresponding to the value of the variable B at this time. The obtained representative vector value is y.

で表される関係が成り立つので、この式を用いることで、相関係数ｃを算出することができる。

Then, the process proceeds to step SS50, and the control unit 301 obtains a correlation coefficient that is an index indicating the correlation (degree of similarity) between the x and the y by using a known appropriate method. The correlation value of the unit represented by the unit ID corresponding to the value of the variable B at this point in time with respect to the unit represented by the unit ID corresponding to the value is calculated. That is, the procedure of step SS50 functions as a correlation calculation unit described in each claim. Specifically, when the correlation coefficient is c, the above two sets of data strings (x, y) = {(x _i , y _i )} (i = 1, 2,..., N) are given. In the case of

Therefore, the correlation coefficient c can be calculated by using this equation.

  Thereafter, in step SS60, the control unit 301 accesses the unit-specific correlation value database 3074 (see FIG. 6) stored in the mass storage device 307, and calculates the value of the correlation coefficient c calculated in step SS50. That is, the correlation value of the unit represented by the unit ID corresponding to the value of the variable B at this time is stored for the unit represented by the unit ID corresponding to the value of the variable A at this time.

  Then, the process proceeds to step SS70, where the control unit 301 determines whether the value of the variable B is equal to the number Bmax of unit IDs. If B <Bmax, the determination at Step SS70 is not satisfied, and the routine goes to Step SS80. In step SS80, the control unit 301 adds 1 to the value of the variable B. Then, it returns to said step SS40 and repeats the same procedure. On the other hand, if B = Bmax, the determination at Step SS70 is satisfied, and the routine goes to Step SS90.

  In step SS90, the control unit 301 determines whether the value of the variable A is equal to the number Amax of unit IDs. Note that Amax = Bmax. If A <Amax, the determination at Step SS90 is not satisfied, and the routine goes to Step SS100. In step SS100, the control unit 301 adds 1 to the value of the variable A. Then, it returns to said step SS20 and repeats the same procedure. On the other hand, if A = Amax, the determination in step SS90 is satisfied, and this flow ends.

  A control procedure related to determination and reproduction of advertisement information to be advertised, which is executed by the control unit 101 of the karaoke apparatus 100, will be described with reference to FIG.

  In FIG. 9, this process is started when the power of the karaoke apparatus 100 is turned on by, for example, an employee of a karaoke store or the like.

  First, in step SK5, the control unit 101 accesses the login table 1071 (see FIG. 2) stored in the large-capacity storage device 107, and determines whether a user ID is newly stored or cleared. Thereby, it is determined whether there is a user who has newly logged in to the My Page or a user who has newly logged out from the My Page. When a user ID is newly stored in the login table 1071 or when a user ID is newly cleared from the login table 1071, a user who has newly logged in to My Page or a user who has newly logged out from My Page Is satisfied, the determination at step SK5 is satisfied, and the routine goes to Step SK100.

  In step SK100, the control unit 101 executes a similar unit determination process of acquiring a first unit ID corresponding to each user in the login state and determining a second unit ID for each first unit. The detailed procedure of step SK100 will be described with reference to FIG.

  In FIG. 10, first, in step SK105, the control unit 101 initializes a similar unit buffer for each user on a memory such as a RAM of the control unit 101. This similar unit buffer for each user is a buffer for storing the user ID of the user in the login state in association with the first and second unit IDs corresponding to the user.

  Thereafter, in step SK110, the control unit 101 accesses the login table 1071, and performs the login operation as a predetermined operation up to this point, that is, the number of user IDs stored at this time, and enters the login state. Detect the number of users. The number of users in the detected login state is m. The predetermined operation is not limited to the login operation. For example, the music selection operation may be a predetermined operation.

  In step SK120, the control unit 101 sets the user ID stored in the login table 1071, that is, the value of the variable j for counting the users in the login state to 1.

  Thereafter, in step SK125, the control unit 101 initializes a unit-specific correlation value buffer on a memory such as a RAM of the control unit 101. This unit-specific correlation value buffer is a buffer for storing the unit ID of each unit and the correlation value of each unit with respect to the first unit in association with each other.

  Then, the process proceeds to step SK130, where the control unit 101 accesses the login table 1071 and acquires the jth user ID.

  Thereafter, in step SK140, the control unit 101 accesses the user unit classification database 3073 (see FIG. 5) stored in the mass storage device 307 of the host server 300 via the communication control unit 106 and the networks NW1 and NW2. To do. Then, the user ID in the user unit classification information stored in the user unit classification database 3073 using the user ID acquired in step SK130 (the user ID related to the user acquired based on the user's login operation) as a key. The unit ID associated with, that is, the first unit ID is acquired.

  As will be described later, step SK140 is repeatedly executed until the value of variable j becomes equal to the detected value m in step SK110, so that the control unit 101 results in the plurality of steps acquired in step SK130. A plurality of first unit IDs corresponding to each of a plurality of users in the login state can be acquired based on the user IDs. That is, the procedure of step SK140 functions as unit information acquisition means described in each claim.

  Then, the process proceeds to step SK150, where the control unit 101 transmits the unit-specific correlation value database 3074 (see FIG. 6) stored in the mass storage device 307 of the host server 300 via the communication control unit 106 and the networks NW1 and NW2. To access. Then, using the first unit ID acquired in step SK140 as a key, the correlation value of each unit with respect to the first unit represented by the first unit ID is acquired. Then, the acquired correlation value of each unit with respect to the first unit is stored in the unit-specific correlation value buffer in association with the unit ID of each unit.

  Thereafter, in step SK160, control unit 101 rearranges the plurality of records in the unit-specific correlation value buffer in descending order with respect to the correlation values included in the records. Note that the correlation value of the same unit as the first unit with respect to the first unit represented by the first unit ID acquired in step SK140 is “1” as the maximum value. Therefore, when the records are rearranged as described above, the unit ID included in the first record (the highest record) of the unit-specific correlation value buffer becomes the first unit ID.

  Then, the process proceeds to step SK170, where the control unit 101 acquires unit IDs included in the upper predetermined number (for example, five) records of the unit-specific correlation value buffer. Then, among the acquired unit IDs, the unit ID included in the first record (the unit ID related to the unit whose correlation value with respect to the first unit is “1”) is used as the first unit ID representing the first unit. Unit IDs determined and included in other records (unit IDs related to units whose correlation values for the first unit are within a predetermined range), in this example, a predetermined number of records in descending order of correlation values (however, the first record) 2) is determined as a second unit ID representing a second unit having a predetermined similar correlation. The determined first and second unit IDs are stored in the user-specific similar unit buffer in association with the user ID acquired in step SK130.

  As will be described later, this step SK170 is repeatedly executed until the value of the variable j becomes equal to the number m of users in the login state detected in step SK110. A predetermined number of units (except for the unit with the highest correlation value) are assigned a predetermined similarity in descending order of the correlation value for each of the plurality of first units represented by the plurality of first unit IDs acquired in step SK140. The second unit ID representing the second unit having the correlation can be determined for each first unit. That is, the procedure of this step SK170 functions as a similar unit determination means described in each claim.

  Thereafter, in step SK180, the control unit 101 determines whether or not the value of the variable j is equal to the number m of users in the login state detected in step SK110. If j <m, it is considered that the storage of the first and second unit IDs corresponding to the users who are still logged in to the user-specific similar unit buffer is not completed, and the determination in step SK180 is not satisfied. The process proceeds to step SK190. In step SK190, the control unit 101 adds 1 to the value of the variable j. Thereafter, the procedure returns to step SK125 and the same procedure is repeated. When step SK125 or the like is repeatedly executed and j = m, it is considered that the storage of the first and second unit IDs corresponding to the users who are logged in to the similar unit buffer for each user is completed. When the determination at step SK180 is satisfied, this routine is terminated.

  Returning to FIG. 9, when step SK100 is completed as described above, the process proceeds to step SK200. In step SK200, the control unit 101 executes an advertisement determination process for determining advertisement information to be advertised. The detailed procedure of step SK200 will be described with reference to FIG.

  In FIG. 11, first, in step SK202, the control unit 101 initializes an advertisement reproduction list buffer on a memory such as a RAM of the control unit 101. This advertisement reproduction list buffer is a buffer for storing an advertisement ID of advertisement information to be advertised.

  Thereafter, in step SK210, the control unit 101 sets the value of the variable k for counting the records in the similar unit buffer for each user to 1.

  Then, proceeding to step SK220, the control unit 101 acquires a unit ID included in the kth record of the similar unit buffer for each user.

  Thereafter, in step SK230, the control unit 101 accesses the unit-specific advertisement database 3075 (see FIG. 7) stored in the mass storage device 307 of the host server 300 via the communication control unit 106 and the networks NW1 and NW2. To do. Then, using the unit ID acquired in step SK220 as a key, an advertisement ID associated with the unit ID in the advertisement classification information stored in the unit-specific advertisement database 3075 is acquired. Then, the acquired advertisement ID is stored in the advertisement reproduction list buffer. Specifically, when the unit ID acquired in step SK220 is the first unit ID, an advertisement ID associated with the first unit ID in the advertisement classification information is acquired, and an advertisement reproduction list buffer is obtained. To store. On the other hand, if the unit ID acquired in step SK220 is the second unit ID, the advertisement ID associated with the second unit ID in the advertisement classification information is acquired and stored in the advertisement reproduction list buffer. . Note that storing the advertisement ID in the advertisement reproduction list buffer substantially corresponds to determining the advertisement information represented by the advertisement ID as an advertisement target. That is, storing the advertisement ID associated with the first unit ID in the advertisement reproduction list buffer corresponds to advertisement information represented by the advertisement ID (first advertisement information described in each claim. (Referred to as “first advertisement information”) is determined as an advertisement target. On the other hand, storing the advertisement ID associated with the second unit ID in the advertisement reproduction list buffer corresponds to advertisement information represented by the advertisement ID (second advertisement information described in each claim. (Referred to as “second advertisement information”) is determined as an advertisement target.

  As will be described later, this step SK230 is repeatedly executed until the value of the variable k becomes equal to the number of records kmax in the user-specific similar unit buffer. A plurality of first advertisement information associated with each of a plurality of first unit IDs stored in the buffer and a plurality of second advertisements associated with an advertisement ID associated with a plurality of second unit IDs. Advertisement information can be determined as an advertising target. As described above, in step SK230, the control unit 101 determines advertisement information to be advertised based on the plurality of first and second unit IDs stored in the similar unit buffer for each user. That is, the procedure of step SK230 functions as an advertisement determination unit described in each claim.

  Then, the process proceeds to step SK240, and the control unit 101 determines whether or not the value of the variable k is equal to the number of records kmax in the user-specific similar unit buffer. If k <kmax, it is considered that the determination of the advertisement information to be advertised has not yet been completed, and the determination at step SK240 is not satisfied, and the routine goes to step SK250. In step SK250, the control unit 101 adds 1 to the value of the variable k. Thereafter, the process returns to step SK220 and the same procedure is repeated. Then, when step SK220 and the like are repeatedly executed and k = kmax, it is considered that the determination of the advertisement information to be advertised is completed, the determination at step SK240 is satisfied, and this routine is ended.

  Returning to FIG. 9, when step SK200 is completed as described above, the process proceeds to step SK10. In step SK10, the control unit 101 sets the value of the variable i for counting the advertisement ID stored in the advertisement reproduction list buffer to 1. Thereafter, the process proceeds to step SK15.

  On the other hand, if the user ID is not newly stored in the login table 1071 or the user ID is not newly cleared from the login table 1071 in step SK5, the user who has newly logged in to My Page, or Since it is considered that there is no user who has newly logged out from My Page, the determination in step SK5 is not satisfied, and the process directly proceeds to step SK15.

  In step SK15, the control unit 101 detects the number of advertisement IDs stored in the advertisement reproduction list buffer. The number of detected advertisement IDs is n.

  Then, the process proceeds to step SK20, and the control unit 101, after the reproduction of one performance music by the reproduction unit 102, has not been reserved for the next performance music by any user, that is, the performance music and the performance music. It is determined whether or not the interval is between so-called songs. Until the interval is between songs, the determination in step SK20 is not satisfied, and the procedure returns to step SK5 and the same procedure is repeated. And if it becomes between music, determination of step SK20 will be satisfy | filled and it will move to step SK25.

  In step SK25, the control unit 101 determines whether or not the number n of advertisement IDs detected in step SK15 is greater than zero. If n = 0, it is considered that no advertisement ID is stored in the advertisement reproduction list buffer, the determination in step SK25 is not satisfied, and the routine goes to step SK30.

  In step SK30, the control unit 101 reads out advertisement information determined as a default among a plurality of advertisement information output in advance from the advertisement distribution server 400 and stored in the large-capacity storage device 107. Alternatively, advertisement information randomly selected from the plurality of advertisement information may be read out.

  Thereafter, in step SK35, the control unit 101 outputs a control signal to the playback unit 102, and after the playback of one performance song, the playback of the next performance song is started, that is, the performance song is reserved. The advertisement information read in step SK30 is played back until it is displayed. In other words, the playback unit 102 is controlled to play back the advertisement information read out in step SK30 between songs. As a result, the video related to the advertisement information is displayed on the display unit 103, the sound related to the advertisement information is output from the audio output unit 104, and the advertisement is provided to the users existing in the karaoke room KR. In addition, when the performance music is reserved during the reproduction of the advertisement information, the reproduction of the advertisement information is temporarily stopped and the reproduction of the performance music is started. Then, when it is again between songs, the reproduction of the paused advertisement information is resumed. When the reproduction of one piece of advertisement information is completed, the process returns to step SK5 and the same procedure is repeated.

  On the other hand, if n> 0 in step SK25, it is considered that at least one advertisement ID is stored in the advertisement reproduction list buffer, the determination in step SK25 is satisfied, and the process proceeds to step SK40. .

  In step SK40, the control unit 101 acquires the i-th advertisement ID stored in the advertisement reproduction list buffer.

  Then, the process proceeds to step SK45, where the control unit 101 displays the advertisement represented by the advertisement ID acquired in step SK40 from among a plurality of advertisement information output in advance from the advertisement distribution server 400 and stored in the large-capacity storage device 107. Read information. This substantially corresponds to outputting advertisement information to be advertised determined in step SK230 in FIG. That is, the procedure of step SK45 functions as an advertisement output unit described in each claim.

  Thereafter, in step SK50, the control unit 101 reproduces the advertisement information read in step SK45 until the performance music is reserved in substantially the same manner as in step SK35. When the reproduction of one piece of advertisement information is completed, the process proceeds to step SK55.

  In step SK55, the control unit 101 determines whether or not the value of the variable i is equal to the number n of advertisement IDs detected in step SK15. If i <n, it is considered that all of the advertisement information determined as the advertisement target has not been reproduced yet, and the determination at step SK55 is not satisfied, and the routine goes to step SK60. In step SK60, the control unit 101 adds 1 to the value of the variable i. Thereafter, the process returns to step SK5 and the same procedure is repeated. On the other hand, if i = n, it is considered that all of the advertisement information determined as the advertising target has already been reproduced, the determination at step SK55 is satisfied, and the routine goes to step SK65. In step SK65, the control unit 101 initializes the value of the variable i to 1. Then, the process returns to step SK5 and the same procedure is repeated. The process shown in FIG. 9 is ended when the karaoke apparatus 100 is turned off by an employee of a karaoke store or the like.

  As described above, in the music playback system 1 according to the present embodiment, when a plurality of users perform a predetermined operation (login operation in the above example), the plurality of users acquired according to the predetermined operation are related. Based on the plurality of user IDs, a plurality of first unit IDs corresponding to each of the plurality of users are acquired according to the user unit classification information stored in the user unit classification database 3073 (see FIG. 5) (FIG. 5). 10 step SK140). The first unit ID for each user is used to determine advertisement information to be advertised. Thereby, the advertisement information directly linked to the preference of each of the plurality of users can be read from the mass storage device 307 and provided to each user.

  In the present embodiment, after a plurality of first unit IDs corresponding to a plurality of users are obtained as described above, for each first unit represented by each first unit ID, For each of the plurality of first units, a second unit having a predetermined similarity correlation (in the above example, a predetermined number in the descending order of the correlation value for each of the plurality of first units) is specified, and the second unit is Second unit IDs to be represented are determined (see step SK170 in FIG. 10). Then, advertisement information to be advertised is determined based on each of the second unit IDs (see step SK230 in FIG. 11). Thereby, in addition to the advertising information directly related to each user's preference as described above, it is possible to provide each user with advertising information having a taste that is relatively close to each user's preference. As a result, the content of the advertisement provided to the user at the time of service using the performance music data can be effectively expanded, and the advertising effect can be enhanced.

  In this embodiment, in particular, in step SK230 in FIG. 11, a plurality of first advertisements in which the advertisement ID is associated with each of the plurality of first unit IDs acquired in step SK140 in FIG. 10 by the advertisement classification information. Information and a plurality of second advertisement information in which an advertisement ID is associated with each of the plurality of second unit IDs determined for each first unit in step SK170 of FIG. Determine as. By doing in this way, each user is provided with advertisement information directly related to his / her preference and advertisement information having a taste relatively close to his / her preference. Thereby, the content of the advertisement to provide can be expanded effectively for every user, and an advertising effect can be heightened.

  In the present embodiment, in particular, a correlation value representing the degree of similar correlation between two units is calculated (see step SS60 in FIG. 8). Then, in step SK170 of FIG. 10, unit IDs related to a predetermined number of second units are determined as second unit IDs in descending order of the correlation value for each first unit. Thereby, the 2nd unit showing the preference comparatively close to each user's preference can be specified smoothly by using the correlation value computed as mentioned above as a numerical index. As a result, the second unit ID and the second advertisement information can be determined easily and reliably, and the contents of the advertisement provided to the user can be reliably expanded.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and technical idea of the present invention. Hereinafter, such modifications will be sequentially described.

(1) When the range of similar correlation is set according to the number of logged-in users, that is, the correlation value for the first unit used to identify the second unit according to the number of users who performed the login operation. The range may be set variably.

  In this variation, the database storage area of the large-capacity storage device 307 of the host server 300 includes a correlation threshold database 3076 (described later) in addition to the various databases stored in the database storage area in the above embodiment. 12) is stored.

  FIG. 12 shows an example of the contents stored in the correlation threshold value database 3076.

  As shown in FIG. 12, the correlation threshold value database 3076 includes a correlation threshold value that is a threshold value of the correlation value for the first unit, corresponding to the number of logged-in users, which is the number of users who are logged in. Is remembered.

  In the example shown in FIG. 12, the correlation threshold corresponding to the case where the number of logged-in users is 1 [person] is “0.6”, and the correlation threshold corresponding to the case where the number of logged-in users is 2 [person]. Is “0.65”, the correlation threshold corresponding to the case where the number of logged-in users is 3 [persons] is “0.7”, and the correlation threshold corresponding to the case where the number of logged-in users is 4 [persons] Is “0.75”, the correlation threshold corresponding to the case where the number of logged-in users is 5 [persons] is “0.8”, and the correlation threshold corresponding to the case where the number of logged-in users is 6 [persons] Is “0.85”, and the correlation threshold corresponding to the case where the number of login users is 7 [persons] is the correlation threshold corresponding to the case where the number of “0.9” login users is 8 [persons] or later. Is “0.95”.

  Here, in the control procedure related to the determination and reproduction of the advertisement information to be advertised, which is executed by the control unit 101 of the karaoke apparatus 100 in the present modification, the difference from the above-described FIG. 9 is the procedure of step SK100. The other procedures are almost the same as those in FIG. Hereinafter, the detailed procedure of step SK100 in this modification will be described with reference to FIG. FIG. 13 corresponds to FIG. 10 described above. The same steps as those in FIG. 10 are denoted by the same reference numerals and description thereof is omitted.

  13 differs from FIG. 10 described above in that step SK170 ′ is provided instead of step SK170, and step SK115, step SK162, step SK164, step SK166, step SK172, and step SK174 are newly provided. . That is, in step SK110, the number of users in the login state is detected by performing the login operation up to this point. If the detected number of users in the login state is m, the process proceeds to newly provided step SK115.

  In step SK115, the control unit 101 accesses the correlation threshold value database 3076 (see FIG. 12) stored in the mass storage device 307 of the host server 300 via the communication control unit 106 and the networks NW1 and NW2. . Then, a correlation threshold value corresponding to the number of users m in the login state is acquired using the number of users m in the login state detected in step SK110 as a key. And the acquired correlation threshold value is set to M.

  The subsequent steps SK120, SK125, SK130, SK140, SK150, and SK160 are the same as those in FIG. In step SK160, when the plurality of records in the unit-specific correlation value buffer are rearranged in descending order with respect to the correlation values included in the record, the process proceeds to newly provided step SK162.

  In step SK162, the control unit 101 sets the value of the variable p for counting the records in the unit-specific correlation value buffer to 1 as described above.

  Thereafter, in step SK164 newly provided, the control unit 101 acquires a correlation value included in the p-th record of the unit-specific correlation value buffer. The acquired correlation value is N.

  Then, the process proceeds to newly provided step SK166, and the control unit 101 determines whether the correlation value N acquired in step SK164 is equal to or larger than a predetermined range, in this example, the correlation threshold value M acquired in step SK115. Determine if. If N ≧ M, the determination at step SK166 is satisfied, and the routine goes to step SK170 ′, which is provided instead of step SK170.

  In step SK170 ′, the control unit 101 acquires the unit ID included in the p-th record of the unit-specific correlation value buffer. Then, the acquired unit ID is stored in the above-described similar unit buffer for each user in association with the user ID acquired in step SK130. Specifically, when the value of the variable p is 1, the unit ID (unit ID related to the unit whose correlation value for the first unit is “1” included in the first record of the unit-specific correlation value buffer). ) To get. Then, the acquired unit ID is determined as the first unit ID representing the first unit, and stored in the similar unit buffer for each user. On the other hand, when the value of the variable p is 2 or more, the unit ID included in the p-th record of the unit-specific correlation value buffer (unit ID related to a unit whose correlation value for the first unit is within a predetermined range), this In the example, a unit ID included in a record where N ≧ M (excluding the first record) is acquired. Then, the acquired unit ID is determined as a second unit ID representing the second unit having a predetermined similar correlation, and stored in the similar unit buffer for each user.

  In step SK170 ′, as will be described later, the value of variable j is equal to the number m of users in the login state detected in step SK110, or the number of records in the unit-specific correlation value buffer. Since it is repeatedly executed until it becomes equal to pmax, as a result, the control unit 101 correlates each of the plurality of first units represented by the plurality of first unit IDs acquired in the above-described step SK140 (the above-described step SK164). A unit whose correlation value N) obtained in step SK115 is equal to or greater than the correlation threshold value M obtained in step SK115 (except for a unit where N = 1) is a second unit having a predetermined similar correlation. Can be determined for each first unit. In other words, the procedure of step SK170 ′ functions as a similar unit determination unit described in each claim.

  Thereafter, in step SK172, the control unit 101 determines whether or not the value of the variable p is equal to the number of records pmax in the unit-specific correlation value buffer. If p <pmax, it is considered that the correlation values included in all the records in the unit-specific correlation value buffer have not been compared with the correlation threshold value M acquired in step SK115, and step SK172. This determination is not satisfied, and the routine goes to Step SK174. In step SK174, the control unit 101 adds 1 to the value of the variable p. Thereafter, the process returns to step SK164 and the same procedure is repeated.

  On the other hand, since N <M in step SK166, the determination in step SK166 is not satisfied, and because p = pmax in step SK172, the correlation values included in all the records in the unit-specific correlation value buffer. Is compared with the correlation threshold value M acquired in step SK115, and if the determination in step SK172 is satisfied, the process proceeds to step SK180.

  The subsequent steps SK180 and SK190 are the same as those in FIG.

  As described above, in this modification, a range that is equal to or greater than the correlation threshold value M acquired in step SK115 is set as a predetermined range, and the value of the correlation threshold value M is the login detected in step SK110. It changes according to the number of users m in the state. Therefore, in step SK115, the control unit 101 substantially changes the predetermined range according to the number m of users in the login state detected in step SK110, that is, the number of users who have performed the login operation. It is set to. That is, the procedure of step SK115 functions as a range setting unit described in each claim.

  According to this modification, the predetermined range is variably set according to the number of users who have performed the login operation. Thereby, for example, when the number of users is relatively large, the range of the similar correlation used for specifying the second unit can be narrowed. In this case, it is possible to reduce the probability that an advertisement that is far from a user's preference and is not of interest to the user is provided.

(2) When targeting an advertisement for a second unit that is common to a plurality of users That is, advertisement information corresponding to a second unit that is common to two or more users included in a plurality of users who are logged in. It may be determined as an advertising target.

  Here, in the control procedure related to the determination and reproduction of the advertisement information to be advertised, which is executed by the control unit 101 of the karaoke apparatus 100 in this modification, the difference from the above-described FIG. 9 is the procedure of step SK200. The other procedures are almost the same as those in FIG. Hereinafter, the detailed procedure of step SK200 in this modification will be described with reference to FIG. FIG. 14 corresponds to FIG. 11 described above. The same steps as those in FIG. 11 are denoted by the same reference numerals and description thereof is omitted.

  In FIG. 14, first, in step SK202, the control unit 101 initializes the advertisement reproduction list buffer as described above with reference to FIG.

  Thereafter, in step SK300, the control unit 101 executes a common similar unit determination process for determining a second unit ID related to a second unit that is common to two or more users who have performed the login operation. The detailed procedure of step SK300 will be described with reference to FIG.

  In FIG. 15, first, in step SK 305, the control unit 101 initializes a unit-by-unit user number buffer on a memory such as a RAM of the control unit 101. This unit-specific user number buffer is a buffer for storing the unit ID of each unit and the number of user IDs in association with each other.

  Then, the process proceeds to step SK310, where the control unit 101 classifies the user IDs stored in the above-described similar unit buffer for each user for each unit ID, and counts the number of user IDs for each unit ID. Then, the count result, that is, the number of user IDs for each unit ID is stored in the unit-specific user number buffer in association with each unit ID.

  Thereafter, in step SK320, the control unit 101 rearranges the plurality of records in the unit-specific user number buffer so as to be in descending order with respect to the number of user IDs included in the record.

  Then, the process proceeds to step SK330, and the control unit 101 initializes a common similar unit buffer on a memory such as a RAM of the control unit 101. The common similar unit buffer is a buffer for storing a second unit ID that is common to two or more users among a plurality of users in the login state.

  Thereafter, in step SK340, the control unit 101 sets the value of the variable q for counting the records in the unit-by-unit user number buffer to 1.

  Then, proceeding to step SK350, the control unit 101 acquires the number of user IDs included in the qth record in the unit-specific user number buffer. Then, let Q be the number of the acquired user IDs.

  Thereafter, in step SK360, the control unit 101 determines whether or not the number Q of user IDs acquired in step SK350 is two or more. If Q ≧ 2, the unit ID included in the q-th record in the unit-by-unit user number buffer is regarded as a second unit ID that is common to the two or more users, and the determination in step SK360 is performed. Is satisfied, and the routine goes to Step SK370.

  In step SK370, the control unit 101 acquires a unit ID included in the q-th record in the unit-by-unit user number buffer, that is, a second unit ID that is common to the two or more users. Then, the acquired second unit ID is stored in the common similar unit buffer.

  Then, the process proceeds to step SK380, where the control unit 101 determines whether or not the value of the variable q is equal to the record number qmax in the unit-by-unit user number buffer. If q <qmax, it is considered that the storage of the second unit ID that is common to the two or more users in the common similar unit buffer has not been completed yet, and the determination in step SK380 is not satisfied, and the step Move on to SK390. In step SK390, control unit 101 adds 1 to the value of variable q. Thereafter, the procedure returns to step SK350 and the same procedure is repeated.

  On the other hand, since Q = 1 in step SK360, it is considered that the unit ID included in the qth and subsequent records in the unit-specific user number buffer is not the second unit ID that is common to the two or more users. If the determination in step SK360 is not satisfied, and because q = qmax in step SK380, it is considered that the storage of the second unit ID common to the two or more users in the common similar unit buffer has ended. If the determination at step SK380 is satisfied, this routine is terminated.

  Returning to FIG. 14, when step SK300 is completed as described above, the process proceeds to step SK205. In step SK205, the control unit 101 sets a variable r for counting the unit ID stored in the common similar unit buffer to 1.

  Thereafter, in step SK215, the control unit 101 acquires the rth unit ID stored in the common similar unit buffer, that is, the second unit ID that is common to the two or more users.

  Then, the process proceeds to step SK225, and the control unit 101 stores the unit-specific advertisement database 3075 (see FIG. 7) stored in the mass storage device 307 of the host server 300 via the communication control unit 106 and the networks NW1 and NW2. to access. The advertisement ID associated with the unit ID in the advertisement classification information stored in the unit-specific advertisement database 3075 using the second unit ID common to the two or more users acquired in step SK215 as a key. To get. Then, the acquired advertisement ID is stored in the advertisement reproduction list buffer. This is substantially common to two or more users included in a plurality of logged-in users among the plurality of second unit IDs determined for each first unit ID in step SK170 described above. Determining the advertisement information (corresponding to the third advertisement information described in each claim; hereinafter referred to as “third advertisement information” as appropriate) represented by the advertisement ID associated with the second unit ID as an advertisement target. It corresponds to.

  Note that this step SK225 is repeatedly executed until the value of the variable r becomes equal to the unit ID number rmax stored in the common similar unit buffer, as will be described later. A plurality of third advertisement information in which an advertisement ID is associated with each of a plurality of unit IDs (second unit IDs common to two or more users) stored in the similar unit buffer are determined as advertisement targets. be able to.

  Thereafter, in step SK235, the control unit 101 determines whether or not the value of the variable r is equal to the unit ID number rmax stored in the common similar unit buffer. If r <rmax, it is considered that the storage of the advertisement ID associated with the second unit ID common to the two or more users in the advertisement reproduction list buffer has not been completed yet, and step SK235. This determination is not satisfied, and the routine goes to Step SK245. In step SK245, the control unit 101 adds 1 to the value of the variable r. Thereafter, the process returns to step SK215 and the same procedure is repeated. Then, when step SK215 or the like is repeatedly executed and r = rmax, the advertisement ID associated with the second unit ID common to the two or more users is stored in the advertisement reproduction list buffer. It is considered that the process has ended, the determination at step SK235 is satisfied, and the routine goes to Step SK255.

  In step SK255, the control unit 101 accesses the unit-specific advertisement database 3075. In the advertisement classification information stored in the unit-specific advertisement database 3075, the plurality of first unit IDs corresponding to the plurality of users in the login state acquired in step SK140 in FIG. Each advertisement ID associated with each first unit ID is acquired. The acquired plurality of advertisement IDs are stored in the advertisement reproduction list buffer. This substantially corresponds to determining a plurality of first advertisement information in which an advertisement ID is associated with each of the plurality of first unit IDs acquired in the above-described step SK140 as an advertisement target. Thereafter, this routine is terminated.

  In addition, in the above, the procedure of step SK225 and step SK255 functions as an advertisement determination means described in each claim.

  As described above, in the present modification, in step SK225 of FIG. 14, common to two or more users among the plurality of second unit IDs determined for each first unit in step SK170 of FIG. 10. The third advertisement information in which the advertisement ID is associated with the second unit ID by the advertisement classification information is determined as the advertisement target. In step SK255 in FIG. 14, a plurality of first advertisement information in which the advertisement ID is associated with each of the plurality of first unit IDs acquired in step SK140 in FIG. Determine as. Thus, in this modification, for each user, the advertisement information directly connected to his / her preference and the advertisement information that is common to two or more users among the advertisement information whose preference is relatively close to each user's preference, Provided to each user. In this way, by narrowing the provision of advertisement information with a preference relatively similar to the user's preference to only information common to a plurality of users, for example, when the number of users is relatively large, far away from the preference of a certain user, It is possible to reduce the probability that an advertisement that is not of interest to the user is provided.

(3) Others In addition, in the above, the advertisement delivery server 400 outputs a plurality of advertisement information to the karaoke apparatus 100 in advance, and the control unit 101 of the karaoke apparatus 100 determines the advertisement target among the plurality of advertisement information. Advertisement information (or advertisement information determined as default) to be played is played by the playback unit 102 after the end of playback of one performance piece and before the start of the next playback, but is not limited thereto. For example, the display screen of the display unit 103 may be divided into a plurality of parts, one of which may display the lyrics telop corresponding to the performance song and the other screen may display the advertisement information.

  In addition, for example, when the advertisement distribution server 400 outputs advertisement information to the remote controller 200 at an appropriate timing, and it is determined that the operation unit 205 has not been operated for a certain period of time, the control unit 201 of the remote controller 200 performs the above advertisement target The advertisement information (or advertisement information determined as default) may be displayed on the entire display unit 203. Alternatively, the display screen of the display unit 203 may be divided into a plurality of screens, and a music selection screen for performance music may be displayed on one screen, and the advertisement information may be displayed on another screen.
