  The greatest feature of this embodiment with the above configuration is that the user classification information stored in the user-specific preference database 3071 is applied using the user ID of the registered user acquired based on the login operation of the registered user. Thus, the first unit ID corresponding to the registered user is acquired, and the singer included in the singing history information of the registered user corresponding to the music selection operation of the registered user related to the performance music stored in the singing history table 1071. The purpose is to determine the consistency between the ID and the first unit ID acquired for the registered user. Details will be described below.

  The control procedure regarding the process regarding the determination of advertisement information which the control part 101 of the karaoke apparatus 100 performs using FIG. 7 is demonstrated.

  In FIG. 7, for example, when the karaoke apparatus 100 is turned on by an administrator of the music playback system 1, this flow is started as represented by a “START” position in the drawing.

  First, in step S10, the control unit 101 uses the login table 1071 (see FIG. 2) to determine whether there is a registered user who has logged in to the my page. If the user ID is not stored in the login table 1071, it is considered that there is no registered user logged in to My Page, and the determination in step S10 is not satisfied, and the process waits in a loop. On the other hand, if the user ID is stored in the login table 1071, it is considered that there is a registered user logged in to My Page, and the determination in step S10 is satisfied, and the process proceeds to step S20.

  In step S20, the control unit 101 acquires the user ID of at least one registered user who has logged in to the My Page, that is, at least one user ID stored in the login table 1071. If a plurality of registered users are logged in to My Page, the user IDs of the plurality of registered users stored in the login table 1071 are acquired in step S20. This substantially corresponds to acquiring the user ID of the registered user based on the login operation of the registered user.

  Thereafter, in step S30, the control unit 101 accesses the user-specific preference database 3071 (see FIG. 4) of the host server 300. Then, in the user classification information stored in the user-specific preference database 3071, the unit ID associated with each user ID acquired in step S20, that is, the first unit ID is acquired. In practice, the first unit ID corresponding to the registered user is acquired based on the user classification information stored in the user-specific preference database 3071 based on the user ID of the registered user acquired in step S20. It corresponds to doing. That is, the procedure of step S30 functions as unit information acquisition means described in each claim.

  Then, the process proceeds to step S40, and the control unit 101 determines whether each first unit ID acquired in step S30 corresponds to the predetermined unit ID described above.

  Thereafter, in step S50, the control unit 101 includes the first unit ID corresponding to the predetermined unit ID in the first unit ID acquired in step S30 based on the determination result in step S40. Determine whether or not. In other words, this corresponds to determining whether there is a registered user who belongs to a unit that may want to hide his / her preference among other registered users who are logged in to the My Page. To do.

  In step S50, the first unit ID corresponding to the predetermined unit ID may not be included in the first unit ID acquired in step S30. In this case, it is considered that there is no registered user belonging to a unit that may want to hide his / her preference from other humans among the registered users who are logged in to My Page, and the determination in step S50 is performed. If not satisfied, the process proceeds to step S60.

  In step S60, the control unit 101 determines each first unit ID acquired in step S30 as a unit ID to be advertised. Thereafter, the process proceeds to step S90 described later.

  On the other hand, in step S50, the first unit ID corresponding to the predetermined unit ID may be included in the first unit ID acquired in step S30. In this case, it is considered that there is a registered user who belongs to a unit that may want to hide his / her preference from other people among the registered users who have logged in to My Page, and the determination in step S50 is satisfied. Then, the process proceeds to step S70.

  In step S70, the control unit 101 uses the first unit ID acquired in step S30 as a unit ID for advertising each first unit ID determined as not corresponding to the predetermined unit ID in step S40. Respectively.

  After that, in step S80, the control unit 101 determines that the first unit ID corresponds to the predetermined unit ID in step S40. In other words, the control unit 101 sets the unit that may want to hide its preference from other people. For the registered user to which the user belongs, the user ID acquired in step S20 is stored in a memory such as a RAM of the control unit 101, for example.

  And it moves to step S100 and the control part 101 performs a predetermined singing tendency determination process. Details of step S100 will be described later with reference to FIG.

  After that, in step S90, the control unit 101 determines whether all registered users have logged out from the My Page using the login table 1071. When the user ID is stored in the login table 1071, it is considered that all registered users have not logged out from My Page, and the determination in step S90 is not satisfied, and the process returns to step S20 and the same procedure is repeated. On the other hand, when the user ID is not stored in the login table 1071, it is considered that all registered users have logged out from My Page, the determination in step S90 is satisfied, and this flow ends.

  In addition, in the above, the procedure of step S40 and step S50 functions as a 2nd determination means as described in each claim.

  The detailed procedure of step S100 in FIG. 7 will be described with reference to FIG.

  In FIG. 8, first, in step S105, the control unit 101 acquires a user ID that has not yet been acquired from the user IDs stored in the memory in step S80 of FIG.

  Thereafter, in step S110, the control unit 101 determines whether or not the singing history information of the registered user whose user ID is acquired in step S105 is stored in the singing history table 1072 (see FIG. 3). When the singing history information including the user ID acquired in step S105 is not stored in the singing history table 1072, the singing history of the registered user whose user ID is acquired in step S105 is stored in the singing history table 1072. It is assumed that no information is stored, the determination in step S110 is not satisfied, and the routine goes to step S190 described later. On the other hand, when singing history information including the user ID acquired in step S105 is stored in the singing history table 1072, the registered user whose user ID is acquired in step S105 is stored in the singing history table 1072. It is considered that the singing history information is stored, the determination at Step S110 is satisfied, and the routine goes to Step S120.

  In step S120, the control unit 101 acquires the singer ID included in the singing history information of the registered user whose user ID has been acquired in step S105 from the singing history table 1072. When a plurality of records of the singing history information of the registered user whose user ID has been acquired in step S105 are stored in the singing history table 1072, the registration stored in the singing history table 1072 is stored in this step S120. Singer IDs included in the user's plurality of singing history information are respectively acquired. A record is a unit of data constituting a table.

  And it moves to step S130 and the control part 101 matches with respect to each predetermined unit ID among several singer ID in the singing object classification | category information memorize | stored in the said unit ID-singer ID table 1073 (refer FIG. 5). The obtained first singer ID is acquired. That is, in this step S130, the singer ID related to the most popular singer, in other words, the singer ID related to the singer that most characterizes the unit, in each unit that may want to hide its preference from the other humans. , Are acquired respectively.

  Thereafter, in step S140, the control unit 101 determines whether the first singer ID that matches any of the singer IDs acquired in step S120 is included in the first singer ID acquired in step S130. Determine. In other words, a registered user who is classified as a unit whose user ID is acquired in step S105 and may wish to hide his / her preferences from other humans needs to hide his / her preferences. This is equivalent to determining whether or not you are visiting with another person who is not present or whether you are visiting alone.

  In step S140, the first singer ID acquired in step S130 may include a first singer ID that matches one of the singer IDs acquired in step S120. In this case, a registered user who is classified as a unit that may want to hide his / her preferences from other humans is present with other humans who do not need to hide his / her preferences, or It is considered that one person is visiting, the determination in step S140 is satisfied, and the routine goes to step S150.

  In step S150, the control unit 101 uses the first unit ID acquired for the registered user whose user ID is acquired in step S105, among the first unit IDs acquired in step S30 of FIG. As a unit ID. Thereafter, the process proceeds to step S190 described later.

  On the other hand, in step S140, the first singer ID acquired in step S130 may not include the first singer ID that matches any of the singer IDs acquired in step S120. In this case, it is considered that a registered user classified as a unit that may wish to hide his / her preferences from other humans may wish to hide his / her preferences from other humans. The determination at S140 is not satisfied, and the routine goes to Step S160.

  In step S160, the control unit 101 determines in advance in the singing history table 1072 the number of records necessary for the singing tendency determination of the singing history information of the registered user whose user ID was acquired in step S105. It is determined whether or not more than three records are stored in this example. When the singing history information of the registered user whose user ID is acquired in step S105 is not stored in the singing history table 1072, the determination in step S160 is not satisfied, and the process proceeds to step S190 described later. On the other hand, if the singing history information of the registered user whose user ID is acquired in step S105 is stored in the singing history table 1072, three or more records are stored, the determination in step S160 is satisfied, and the process proceeds to step S200. .

  In step S200, the control unit 101 executes unit information determination processing for determining a unit ID to be associated with the registered user whose user ID is acquired in step S105 from the 100 unit IDs. Details of step S200 will be described later with reference to FIG. In step S200, the unit ID determined as the unit ID associated with the registered user whose user ID is acquired in step S105 corresponds to the second unit identification information described in each claim. Hereinafter, the unit ID will be referred to as a “second unit ID” as appropriate. The second unit ID represents the unit ID of the unit corresponding to the current user's music selection operation as described later.

  Then, the process proceeds to step S170, and the control unit 101 determines the first unit ID acquired in step S30 of FIG. 7 regarding the registered user whose user ID was acquired in step S105 and the step S200 regarding the registered user. It is determined whether or not the second unit ID thus made matches. This is substantially the registered user's singing history information stored in the singing history table 1072 and corresponding to the registered user's song selection operation related to the performance song, of the registered user whose user ID was acquired in step S105. This corresponds to determining the consistency between the singer ID included in the singing history information and the first unit ID acquired in step S30 in FIG. In other words, this corresponds to determining the consistency between the original preference of the registered user and the current music selection operation of the registered user. In other words, this corresponds to determining whether or not the registered user is present with another person who does not need to hide the preference of the registered user, or whether the registered user is visiting alone. That is, the procedure of step S170 functions as a first determination unit described in each claim.

  In step S170, the first unit ID related to the registered user whose user ID was acquired in step S105 may match the second unit ID related to the registered user. In this case, the singer ID included in the singing history information of the registered user is consistent with the first unit ID related to the registered user, in other words, the original preference of the registered user and the Consistent with the registered user's current music selection operation, in other words, the registered user is present with another person who does not need to hide the registered user's preferences, or visited alone The determination at step S170 is satisfied, and the routine goes to step S180.

  In step S180, the control unit 101 acquires the first unit ID acquired for the registered user belonging to the predetermined unit for which the user ID is acquired in step S105, among the first unit IDs acquired in step S30 of FIG. Are determined as unit IDs to be advertised. Alternatively, the second unit ID determined in step S200 regarding the registered user that matches the first unit ID may be determined as the unit ID to be advertised. Thereafter, the process proceeds to step S190.

  On the other hand, in step S170, the first unit ID related to the registered user whose user ID was acquired in step S105 may not match the second unit ID related to the registered user. In this case, the consistency between the singer ID included in the singing history information of the registered user and the first unit ID related to the registered user is not achieved, in other words, the original preference of the registered user and the Consistency with the registered user's current music selection operation is not taken. In other words, it is considered that the registered user may want to hide his / her preferences from other people, and the determination in step S170 is performed. If not satisfied, the process proceeds to step S190. That is, if the determination in step S170 is not satisfied, the first unit ID acquired in step S30 of FIG. 7 for the registered user for which the user ID has been acquired in step S105 and the step for the registered user are described above. The second unit ID determined in S200 is not determined as the unit ID to be advertised.

  In step S190, the control unit 101 determines whether all user IDs have been acquired in step S105 from the user IDs stored in the memory in step S80 of FIG. If all user IDs have not been acquired in step S105, the determination in step S190 is not satisfied, and the process returns to step S105 and the same procedure is repeated. On the other hand, if all user IDs have already been acquired in step S105, the determination in step S190 is satisfied, and this routine ends.

  The detailed procedure of step S200 in FIG. 8 will be described with reference to FIG.

  In FIG. 9, first, in step S210, the control unit 101 acquires each singer ID included in the plurality of singing history information of the registered user whose user ID was acquired in step S105 of FIG. 7 from the singing history table 1072. To do.

  Thereafter, in step S220, the control unit 101 sets the value of the variable J corresponding to any of the 100 unit IDs to 1.

  And it moves to step S230 and the control part 101 is set to the value of the variable J at this time among several singer ID in the singing object classification | category information memorize | stored in the said unit ID-singer ID table 1073 (refer FIG. 5). The above-mentioned n first singer IDs to n-th singer IDs associated with corresponding unit IDs are respectively acquired. That is, in this step S230, in the unit related to the unit ID corresponding to the value of the variable J at this time, the singer ID related to the top n popular singers, in other words, the n singers characterizing the unit. Such a singer ID is acquired.

  Thereafter, in step S240, the control unit 101 includes a number of the plurality of singer IDs acquired in step S210 among the n first singer ID to the nth singer ID acquired in step S230. Count. Then, the count value related to the unit ID corresponding to the value of the variable J at this time is held as N (J).

  In step S250, the control unit 101 determines whether the value of the variable J is equal to the number Jmax of unit IDs (Jmax = 100 in this example). If J <Jmax, the determination at step S250 is not satisfied, and the routine goes to step S260. In step S260, the control unit 101 adds 1 to the value of the variable J. Thereafter, the process returns to step S230 and the same procedure is repeated. If J = Jmax, the determination at step S250 is satisfied, and the routine goes to step S270.

  In step S270, the control unit 101 determines whether or not the count value C (J) in step S240 is 0 in all of the 100 unit IDs. If the count value C (J) at step S240 is not 0 in any of the 100 unit IDs, the determination at step S270 is not satisfied, and the routine goes to step S280.

  In step S280, the control unit 101 selects the unit ID having the maximum count value C (J) from among the unit IDs in which the count value C (J) in step S240 has not become 0, in the step of FIG. The unit ID of the unit corresponding to the current music selection operation of the registered user who has acquired the user ID in S105 is selected. In addition, when there are a plurality of unit IDs having the maximum count value C (J), among those unit IDs, the singer IDs related to the popular singer, that is, the singer IDs with a small value of n are counted more. The unit ID that has been stored may be selected as the unit ID of the unit corresponding to the current music selection operation of the registered user whose user ID was acquired in step S105 of FIG.

  Thereafter, in step S290, the control unit 101 associates the unit ID selected in step S280 among the 100 unit IDs with the registered user whose user ID is acquired in step S105 of FIG. That is, it is determined as the second unit ID. That is, the second unit ID represents a unit ID of a unit corresponding to the current user's music selection operation. Thereafter, this routine is terminated.

  On the other hand, if the count value C (J) in step S240 is 0 in all the 100 unit IDs in step S270, the determination in step S270 is satisfied, and the process proceeds to step S295. .

  In step S295, the control unit 101 associates “XXX”, which is identification information not corresponding to any of the 100 unit IDs, with the unit ID that associates the registered user whose user ID was acquired in step S105 of FIG. The second unit ID is determined. This substantially corresponds to determining that no unit ID is associated with the registered user because there is no unit corresponding to the current music selection operation of the registered user. Thereafter, this routine is terminated.

  As described above, in step S200, the control unit 101 uses the singer ID included in the singing history information of the registered user acquired in step S105 of FIG. 8 and stored in the singing history table 1071. Based on the singing object classification information stored in the unit ID-singer ID table 1073, a second unit ID to be associated with the registered user is determined from the 100 unit IDs. Therefore, all the procedures in step S200, that is, the procedures in steps S210 to S290 and S295 function as unit information determining means described in each claim.

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

  In FIG. 10, for example, when the karaoke apparatus 100 is turned on by the administrator of the music playback system 1, this flow is started as represented by a “START” position in the figure.

  First, in step S510, the control unit 101 is determined as a unit ID to be advertised in step S60 of FIG. 7, or step S70 of FIG. 7, or step S150 of FIG. 8, or step S180 of FIG. Get the unit ID. When there are a plurality of unit IDs determined as unit IDs to be advertised, in step S510, the determined plurality of units are respectively acquired.

  Thereafter, in step S520, the control unit 101 selects any one unit ID from the unit IDs acquired in step S510.

  Then, the process proceeds to step S530, and the control unit 101 acquires an advertisement ID associated with the unit ID acquired in step S520 from the unit-specific advertisement table (see FIG. 6). Thereafter, the advertisement information corresponding to the acquired advertisement ID is determined as the advertisement information to be subsequently reproduced by the reproduction unit 102.

  Thereafter, in step S540, the control unit 101 determines whether or not a reservation for the next performance song has not been made after the end of the reproduction of one performance song, that is, a so-called song interval. Until it is between songs, the determination in step S540 is not satisfied, and the process waits in a loop. And if it becomes between music, determination of step S540 will be satisfy | filled and it will move to step S550.

  In step S550, the control unit 101 reads out the advertisement information determined in step S530 from the mass storage device 107.

  Then, the process proceeds to step S560, where the control unit 101 waits for reservation of the performance song, that is, until the start of reproduction of the next performance song, that is, the advertisement information read in step S550, that is, The reproduction unit 102 is controlled to reproduce the advertisement information associated with the unit ID to be advertised. Thereby, the video related to the advertisement information is displayed on the display unit 103, and the sound related to the advertisement information is output from the audio output unit 104. Note that the playback unit 102 is controlled to play back the advertisement information associated with the unit ID to be advertised, that is, the playback of the advertisement information by the playback unit 102 is substantially different from the advertisement target. This corresponds to outputting the advertisement information associated with the unit ID to be performed. That is, the procedure of step S560 functions as an advertisement information output unit described in each claim.

  Specifically, when the determination in step S50 in FIG. 7 is not satisfied, the first unit ID acquired in step S30 in FIG. 7 is determined as the unit ID to be advertised. The control unit 101 causes the reproduction unit 102 to reproduce the advertisement information associated with the first unit ID. On the other hand, when the determination in step S50 is satisfied, the first unit ID determined as not corresponding to the predetermined unit ID in step S40 in FIG. 7 is determined as the unit ID to be advertised. The control unit 101 causes the reproduction unit 102 to reproduce the advertisement information associated with the first unit ID.

  If the determination in step S140 in FIG. 8 is satisfied, the first unit ID related to the registered user whose user ID was acquired in step S105 in FIG. 8 is determined as the unit ID to be advertised. Therefore, the control unit 101 causes the reproduction unit 102 to reproduce the advertisement information associated with the first unit ID.

  When the determination in step S170 in FIG. 8 is satisfied, the first or second unit ID related to the registered user whose user ID is acquired in step S105 in FIG. 8 is the unit ID to be advertised. Therefore, the control unit 101 causes the reproduction unit 102 to reproduce the advertisement information associated with the first or second unit ID. On the other hand, if the determination in step S170 is not satisfied, the first and second unit IDs related to the registered user whose user ID is acquired in step S105 are not determined as the unit IDs to be advertised, respectively. Therefore, the control unit 101 controls the reproduction unit 102 so as not to reproduce the advertisement information respectively associated with the first and second unit IDs. Note that the playback unit 102 is controlled not to play the advertisement information associated with the first and second unit IDs, that is, the advertisement information associated with the first and second unit IDs is reproduced. The fact that the reproduction by the unit 102 is substantially equivalent to prohibiting the output of advertisement information respectively associated with the first and second unit IDs.

  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 proceeds to step S570.

  In step S570, the control unit 101 determines whether or not a predetermined end operation, for example, power-off of the karaoke apparatus 100 has been performed. If the end operation has not been performed, the determination in step S570 is not satisfied, and the process returns to step S510 and the same procedure is repeated. When the end operation is performed, the determination in step S570 is satisfied, and this flow is ended.

  As described above, in the present embodiment, when a registered user performs the above-described login operation in order to receive the reproduction service of the karaoke apparatus 100, the user ID of the registered user is acquired based on the operation (see FIG. 7 (see step S20). Then, the control unit 101 accesses the user-specific preference database 3071 (see FIG. 4) of the host server 300 using the user ID, and applies the user classification information stored in the user-specific preference database 3071. The first unit ID related to the registered user is acquired (see step S30 in FIG. 7).

  Here, in general, when a user receives a performance music reproduction service using performance music data, the user may come alone, or may be accompanied by another person and come by a plurality of people. Usually, the user's preference can be roughly estimated from the name, type, etc. of the performance song that the user selects and sings. For this reason, there is a possibility that the user selects and sings performance music that is different from the original singing tendency, that is, different from the user's original taste, depending on the face of the person who is accompanied and used. Therefore, in the present embodiment, when the registered user performs a music selection operation, the control unit 101 acquires the first unit ID corresponding to the original preference of the registered user acquired as described above and the singing history. The consistency with the singer ID included in the singing history information corresponding to the operation content of the music selection operation of the specific user stored in the table 1072 (see FIG. 3) is determined (see step S170 in FIG. 8).

  As a result, if the determination in step S170 is satisfied and it is determined that there is a match, the registered user is visiting alone or another person who does not need to hide the preference of the registered user. It can be regarded as visiting. As a result, in this case, various services that match the original preference of the registered user, for example, advertisements that match the first unit ID, recommended music selection information, recommended food and beverage information, and the like may be provided. it can. That is, it is possible to make the service content in line with the intention of the registered user so that his / her preference does not have to be hidden.

  On the other hand, if the determination in step S170 is not satisfied and it is determined that the matching is not achieved, it may be considered that the registered user is present with another person who wants to hide the preference of the registered user. it can. As a result, in this case, it is possible to make the service content in line with the intention of the registered user to stop providing various services that match the original preference of the registered user and hide his / her preference. .

  In the present embodiment, in particular, when a registered user performs a song selection operation for a performance song in order to receive the reproduction service of the karaoke apparatus 100, song history information corresponding to the operation content is stored in the song history table 1072. . The control unit 101 stores the unit ID-singer ID table 1073 (see FIG. 5) described above in the singer ID included in the singing history information of the registered user stored in the singing history table 1072 as described above. By applying the singing target classification information, it is possible to determine the second unit ID associated with the registered user (see FIG. 9). Thereby, the control unit 101 determines whether or not the first unit ID acquired for the registered user matches the second unit ID related to the registered user determined as described above. Consistency between the original preference of the registered user and the current music selection operation of the registered user can be determined.

  As described above, in the present embodiment, the unit ID of the unit corresponding to the current song selection operation of the registered user is determined, and the unit ID and the unit ID of the unit corresponding to the original preference of the registered user are determined. Compare. Thereby, since the intention of the registered user can be detected with high accuracy, the service content in accordance with the intention can be realized with certainty.

  In the present embodiment, the control unit 101 causes the reproduction unit 102 to reproduce the advertisement information associated with the unit ID to be advertised. (See step S560 in FIG. 10). On the other hand, depending on what the user's preference is, the user may not need to hide his / her preference regardless of who the other party is. Sometimes you want to hide your taste. If the user wants to hide his / her preference and outputs advertisement information corresponding to the preference, the user's preference may be estimated by another person who has seen the advertisement, which is not preferable.

  Therefore, in the present embodiment, in particular, the control unit 101 may want to hide the first unit ID related to the registered user acquired as described above from the above-described predetermined unit ID, that is, as described above. It is determined whether the unit ID is a possible unit (see step S40 and step S50 in FIG. 7). When the first unit ID related to the registered user is a predetermined unit ID, the control unit 101 may want to hide his preference from other people as described above. Then, it is determined whether or not the first unit ID and the second unit ID related to the registered user match. If the first unit ID and the second unit ID match, the determination in step S170 is satisfied, and it is not necessary for the registered user to visit alone or to hide the preference of the registered user. It can be regarded as visiting with other people. Thereby, the control unit 101 causes the reproducing unit 102 to reproduce the advertisement information associated with the matched first or second unit ID. Thereby, an advertisement useful for the registered user can be effectively provided in a form in line with the intention of the registered user.

  Here, if the first unit ID and the second unit ID related to the registered user do not match, the determination in step S170 in FIG. 8 is not satisfied, and therefore the registered user needs to hide the preference of the registered user. It can be regarded as visiting with other human beings. In the present embodiment, in particular, when it is determined that the first unit ID related to the registered user and the second unit ID do not match as described above, the control unit 101 sets the first ID related to the registered user. The reproduction unit 102 is controlled so as not to reproduce the advertisement information associated with each of the first and second unit IDs. Thereby, the provision of the advertisement for the registered user can be stopped at all in accordance with the intention of the registered user.

  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 first and second unit IDs do not match, when the advertisement corresponding to the second unit ID is played back In the above embodiment, the first unit ID corresponding to the original preference and the current music selection operation When it is determined that the second unit ID corresponding to the ID does not match, the playback unit 102 is controlled not to play the advertisement information associated with the first and second unit IDs, respectively. Not limited to this. That is, in such a case, the reproduction unit 102 may reproduce the advertisement information associated with the second unit ID corresponding to the current music selection operation.

  The detailed procedure of step S100 in the present modification will be described with reference to FIG. FIG. 11 is a diagram corresponding to FIG. 8 described above. The same steps as those in FIG.

  11 is different from FIG. 8 described above in that step S185 is newly provided between step S170 and step S190. That is, in step S170, it is determined whether or not the first unit ID related to the registered user whose user ID was acquired in step S105 described above matches the second unit ID related to the registered user, and the first unit ID. And the second unit ID do not match, the process proceeds to step S185 newly provided.

  In step S185, the control unit 101 determines the second unit ID determined in the above-described step S200 regarding the registered user whose user ID has been acquired in the above-described step S105 as a unit ID to be advertised. Thereafter, the process proceeds to step S190.

  The procedure other than the above is the same as that in FIG.

  In the present modification, the control procedure relating to the reproduction of advertisement information executed by the control unit 101 of the karaoke apparatus 100 is substantially the same as that in FIG. 10 described above, but the procedures in steps S510 and S560 are slightly different.

  In step S510 in the present modification, unlike step S510 in the above embodiment, the control unit 101 performs the above-described step S60, the above-described step S70, the above-described step S150, the above-described step S180, or the above-described FIG. In step S185, the unit ID determined as the unit ID to be advertised is acquired. Note that, as in step S510 in the above embodiment, when there are a plurality of unit IDs determined as unit IDs to be advertised, in step S510, the determined units are acquired.

  In step S560 in this modification, the control unit 101 performs substantially the same process as in step S560 in the above embodiment. In the present modification, as described above, when the determination in step S170 described above is not satisfied, unlike in the above embodiment, in step S185 in FIG. 11, the user ID is acquired in step S105 described above. The second unit ID related to the registered user is determined as the unit ID to be advertised. In such a case, in step S560 in the present modified example, unlike step S560 in the above embodiment, the control unit 101 causes the reproduction unit 102 to reproduce the advertisement information associated with the second unit ID.

  Here, if the first unit ID and the second unit ID related to the registered user do not match, the determination in step S170 described above is not satisfied, so the registered user needs to hide the preference of the registered user. It can be regarded as visiting with other people. In this modification, in response to this, when it is determined that the first unit ID and the second unit ID related to the registered user do not match as described above, the control unit 101 performs the original registration of the registered user. Advertisement information associated with the first unit ID corresponding to the preference is not reproduced by the reproduction unit 102, but advertisement information associated with the second unit ID is reproduced by the reproduction unit 102. Thereby, provision of the advertisement which can estimate the original preference of the registered user can be stopped in a form in line with the intention of the registered user.

(2) When the first and second unit IDs do not match, the advertisement corresponding to the first or second unit ID is selectively reproduced, that is, the first unit ID corresponding to the original preference and the current unit ID If it is determined that the second unit ID corresponding to the music selection operation does not match, the unit selection probability is calculated so that the calculated unit selection probability is obtained, and the first and second unit IDs are calculated. The reproduction information may be selectively reproduced by the reproduction unit 102.

  In the present modification, the table storage area of the mass storage device 107 of the karaoke apparatus 100 includes a unit combination coefficient table 1075 (see FIG. 12 described later) and a singing frequency coefficient table 1076 (see FIG. 13 described later). ) Is stored.

  FIG. 12 shows an example of the stored contents of the unit combination coefficient table 1075.

  As shown in FIG. 12, the coefficient table 1075 for each unit combination has a coefficient M1 as a first weighting coefficient that is determined in advance according to the combination of the first unit ID and the second unit ID that is assumed in advance. Is remembered.

  The coefficient M1 represents the presence or absence of a contact point between the preference corresponding to the first unit ID and the preference corresponding to the second unit ID. In this example, the maximum value of the coefficient M1 is set to “1” and the minimum value is set to “0” and stored. And the combination with many contact points of the preference corresponding to the first unit ID and the preference corresponding to the second unit ID, in other words, the higher the original preference, the larger the corresponding coefficient M1 (in this example) On the contrary, the smaller the combination of the preference corresponding to the first unit ID and the preference corresponding to the second unit ID, in other words, the lower the original preference level, the lower the corresponding coefficient M1. Is set so as to be small (in this example, close to 0) and stored.

  In the example illustrated in FIG. 12, for example, the coefficient M1 corresponding to the combination of the first unit ID “1” and the second unit ID “1” is set to the maximum value “1”. The coefficient M1 corresponding to the combination of the first unit ID “1” and the second unit ID “2” is set to “0.5”. The coefficient M1 corresponding to the combination of the first unit ID “1” and the second unit ID “3” is set to “0.5”. The coefficient M1 corresponding to the combination of the first unit ID “1” and the second unit ID “4” is set to “0.1”. The coefficient M1 corresponding to the combination of the first unit ID “1” and the second unit ID “5” is set to “0.8”. Although the description is omitted, the corresponding coefficient M1 is similarly set for combinations other than the above.

  FIG. 13 shows an example of the stored contents of the singing frequency coefficient table 1076.

  As shown in FIG. 13, the coefficient table 1076 for each number of singing times stores a coefficient M2 as a second weighting coefficient that is determined in advance according to the size of the number of singing times of the registered user corresponding to the second unit ID. Has been. In this example, the maximum value of the coefficient M2 is set to “1”, and the corresponding coefficient M2 is set and stored so as to decrease as the number of singings increases.

  In the example shown in FIG. 13, the coefficient M2 corresponding to the number of times of singing “0-3 times” is set to the maximum value “1”. The coefficient M2 corresponding to the number of times of singing “4-5 times” is set to “0.9”. The coefficient M2 corresponding to the number of times of singing “6-7 times” is set to “0.8”. The coefficient M2 corresponding to the number of times of singing “8 times or more” is set to the minimum value “0.7”.

  The detailed procedure of step S100 in this modification is demonstrated using FIG. FIG. 14 is a diagram corresponding to FIGS. 8 and 11 described above. The same steps as those in FIG.

  14 is different from FIG. 8 described above in that step S300 is newly provided between step S170 and step S190. That is, in step S170, it is determined whether or not the first unit ID related to the registered user whose user ID was acquired in step S105 described above matches the second unit ID related to the registered user, and the first unit ID. If the second unit ID does not match, the process proceeds to step S300 newly provided.

  In step S300, the control unit 101 executes a predetermined unit information selection process. Details of step S300 will be described later with reference to FIG.

  The procedure other than the above is the same as that in FIG.

  The detailed procedure of step S300 in FIG. 14 will be described with reference to FIG.

  In FIG. 15, first, in step S310, the control unit 101 obtains the registered user whose user ID has been acquired in step S105 described above from the unit-specific coefficient table 1075 (see FIG. 12). The coefficient M1 corresponding to the combination of one unit ID and the second unit ID determined in step S200 described above for the registered user is acquired. Note that the coefficient M1 having a larger value is acquired as the combination having more contact points between the preference corresponding to the first unit ID and the preference corresponding to the second unit ID, in other words, the higher the original preference level is. On the contrary, the coefficient M1 having a smaller value is acquired as the combination having fewer contact points between the preference corresponding to the first unit ID and the preference corresponding to the second unit ID, in other words, the lower the original preference level is. For example, the first unit ID may be “1” and the second unit ID may be “5”. In this case, the coefficient M1 (“0.8” in the example shown in FIG. 12) corresponding to the combination of the first unit ID “1” and the second unit ID “5” is acquired from the unit-specific coefficient table 1075. The

  Thereafter, in step S320, the control unit 101 stores the number of records of the singing history information of the registered user whose user ID is acquired in the above-described step S105, which is stored in the singing history table 1072 (see FIG. 3). Detect the number of sings of registered users.

  And it moves to step S330 and the control part 101 is the number of times of singing of the registered user from which the user ID was acquired in the above-mentioned step S105 detected in the above-mentioned step S320 from the coefficient table 1076 (see FIG. 13) according to the number of times of singing The coefficient M2 corresponding to is obtained. In addition, the coefficient M2 with a large value is acquired, so that there are few singing times. On the contrary, the smaller the number of singing, the smaller the coefficient M2 is acquired. For example, in step S320, it may be detected that the number of times the registered user has sung is “twice”. In this case, the coefficient M2 corresponding to the number of times of singing “2 times” (“1” corresponding to the number of times of singing “0-3 times” in the example shown in FIG. 13) is obtained from the coefficient table 1076 for each number of times of singing. Is done.

  Thereafter, in step S340, the control unit 101 calculates a unit selection probability P using the coefficient M1 acquired in step S310 and the coefficient M2 acquired in step S330. In this example, the control unit 101 calculates the unit selection probability P by multiplying the coefficient M1 acquired in step S310 and the coefficient M2 acquired in step S330. The unit selection probability P is the probability of selecting the advertisement information associated with the first unit ID from the advertisement information associated with the first unit ID and the advertisement information associated with the second unit ID. is there. That is, the greater the value of the unit selection probability P, the higher the probability that the advertisement information associated with the first unit ID will be selected. Conversely, the smaller the value of the unit selection probability P, the more the first unit ID. The probability that the associated advertisement information is selected is reduced. The unit selection probability P may be a probability of selecting the advertisement information associated with the second unit ID. The procedure of Step SS340 functions as a selection probability calculation unit described in each claim.

  In step S350, the control unit 101 obtains the registered user whose user ID has been acquired in step S105 described above so that the unit selection probability P calculated in step S340 is obtained. One unit ID and the second unit ID determined in the above-described step S200 for the registered user are selectively determined as a unit ID to be advertised. Thereafter, this routine is terminated.

  In the present modification, the control procedure relating to the reproduction of advertisement information executed by the control unit 101 of the karaoke apparatus 100 is substantially the same as that in FIG. 10 described above, but the procedures in steps S510 and S560 are slightly different.

  In step S510 in this modification, unlike step S510 in the above embodiment, the control unit 101 performs the above-described step S60, the above-described step S70, the above-described step S150, the above-described step S180, or the above-described FIG. In step S350, the unit ID determined as the unit ID to be advertised is acquired. Note that, as in step S510 in the above embodiment, when there are a plurality of unit IDs determined as unit IDs to be advertised, in step S510, the determined units are acquired.

  In step S560 in this modification, the control unit 101 performs substantially the same process as in step S560 in the above embodiment. In the present modification, as described above, when the determination in step S170 described above is not satisfied, the user ID is acquired in step S105 described above in step S350 in FIG. The first unit ID related to the registered user and the second unit ID related to the registered user are selectively determined as the unit IDs to be advertised. In such a case, in step S560 in the present modification, unlike step S560 in the above embodiment, the control unit 101 is associated with the first or second unit ID that is selectively determined in step S360. The reproduction unit 102 reproduces the advertisement information. This is substantially the advertising information associated with the first unit ID and the advertising information associated with the second unit ID so as to be the unit selection probability P calculated in step S340 of FIG. Is equivalent to selectively reproducing by the reproducing unit 102.

  Here, depending on the content of the user's preference, or depending on the combination of another preference different from the user's preference, the presence or absence of a contact point between the user's preference and the other preference, or the two preferences. There may be differences in the degree of compromise in. In the present modification, in consideration of the above-described tendency, the coefficient M1 corresponding to the combination of the first unit ID and the second unit ID assumed in the unit combination coefficient table 1075 (see FIG. 12) in advance. Is set and stored. When it is determined that the first unit ID and the second unit ID do not match, the control unit 101 refers to the storage contents of the unit combination-specific coefficient table 1075 and refers to the first unit ID and the second unit. Unit selection probability P is calculated using coefficient M1 corresponding to the combination of IDs (see step S340 in FIG. 15). Then, the control unit 101 selectively reproduces the advertisement information corresponding to the first unit ID and the advertisement information corresponding to the second unit ID while achieving the calculated unit selection probability P. To play.

  As a result, it is possible to provide a fine advertisement to the user while prescribing the stochastic advertisement providing characteristic by the coefficient M1.

  In addition, when a user intends to hide the user's preference from other people if possible or to make it difficult to see, the degree of the feeling depends on the face of other people and the circumstances at that time. There may be various changes. In particular, the number of times the user sings may be correlated with the degree of feeling. That is, as described above, when the number of times the user sings is relatively large while the first unit ID and the second unit ID are inconsistent, the user's desire to hide the preference is There is a high possibility that it is gradually getting stronger. Therefore, in the present modification, in consideration of the above-described tendency, a coefficient M2 corresponding to the magnitude of the number of singing by the user is set and stored in the coefficient table 1076 for each number of singing (see FIG. 13) in advance. When it is determined that the first unit ID and the second unit ID do not match, the control unit 101 uses the coefficient M1 based on the stored content of the unit combination coefficient table 1075 and sings the registered user. The unit selection probability P is calculated using the coefficient M2 set taking the number of times into account. Then, the control unit 101 selectively reproduces the advertisement information corresponding to the first unit ID and the advertisement information corresponding to the second unit ID while achieving the calculated unit selection probability P. To play.

  This makes it possible to provide a more detailed advertisement that reflects the user's intention with high accuracy.

  In the above, the advertisement distribution 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 sets the unit ID as an advertisement target among the plurality of advertisement information. The advertisement information associated with the determined unit ID is reproduced by the reproducing unit 102 after the end of reproduction of one performance piece and before the start of the next reproduction, 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 associated with the unit ID determined as the unit ID 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. In this case, the control unit 201 of the remote controller 200 functions as advertisement information output means described in each claim.

  In addition, the flowcharts shown in FIGS. 7, 8, 9, 10 and the like do not limit the present invention to the procedure shown in the above-described flow, and the procedure can be added without departing from the spirit and technical idea of the invention. You may delete or change the order.

  In addition to those already described above, the methods according to the above-described embodiments and modifications may be used in appropriate combination.

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
