  Here, the feature of this embodiment is that when the operator performs a specific operation via the operation unit 25 of the remote controller 20, the ages, genders, and units of a plurality of registrants stored in the group song history database 3320 are stored. Is based on the age information, gender information, and unit ID of a plurality of target persons including the operator and a companion accompanying the operator (second related person, second companion, hereinafter referred to as “operation companion” as appropriate) Karaoke music recommended to the operator is determined based on the group singing history information that satisfies the first condition, and a display based on the determination result is displayed on the display unit 26 of the remote controller 20. Hereinafter, the detailed contents will be described in order.

  In the following description, a case where a plurality of target persons including an operator and an operation companion person are members who are registered as members and who have been authenticated for use will be described as an example.

  That is, in the present embodiment, when the operator performs a predetermined operation via the operation unit 25 of the remote controller 20 when making a music selection, the remote controller 20 displays a predetermined search screen (not shown) on the display unit 26. The When the operator performs a specific operation (for example, touching the portion of the operation unit 25 corresponding to the “search” image displayed on the search screen) via the operation unit 25 of the remote controller 20 with the search screen displayed. In the remote controller 20, a signal indicating that fact (hereinafter referred to as “search signal” as appropriate) is transmitted to the host server 30. Note that the search signal may include information such as the user IDs of the operator and the operation companion. Thereby, in the host server 30, according to the search signal received from the remote controller 20, the age information, the gender information, and the unit ID of each of a plurality of subjects including the operator and the operation companion are retrieved from the user information database 3310. Is acquired.

  For example, as subjects, three subjects including an operator and two operation companions, that is, a subject I who is an operator (a user having a user ID “user9” in the user information database 3310 shown in FIG. 2) Age: 25 years old, gender: male, unit: 1), subject J who is an operation companion (user with user ID “user10” in the user information database 3310 shown in FIG. 2. Age: 30 years old, gender: Female, unit: 2), subject K who is another operation companion (user with user ID “user11” in the user information database 3310 shown in FIG. 2. Age: 40 years old, gender: female, unit: 3) Think of a case. In this case, for the subject I, “25 years old” is acquired as age information, “male” is acquired as sex information, and “1” is acquired as a unit ID. As for the subject J, “30 years old” is acquired as age information, “female” is acquired as sex information, and “2” is acquired as a unit ID. For the subject K, “40 years old” as age information, “female” as sex information, and “3” as a unit ID are acquired.

  Then, in the host server 30, among the plurality of group singing history information stored in the group singing history database 3320, the age, gender, and unit of each of the plurality of registrants are determined for each of the acquired plurality of subjects. It is determined whether or not there is group singing history information that satisfies the first condition based on age information, gender information, and unit ID. In this example, the first condition is set to completely match the age, sex, and unit of each of the plurality of subjects. Therefore, here, among the plurality of group singing history information stored in the group singing history database 3320, the age, gender, and unit of each of the plurality of registrants are the age information of each of the acquired plurality of subjects. It is determined whether there is group singing history information that completely matches the age indicated, the gender indicated by the gender information, and the unit indicated by the unit ID. That is, it is determined whether or not there is group singing history information including the singing histories of a plurality of registrants corresponding to the same age, gender, and preference configuration as the configuration of the age, sex, and preference of the plurality of subjects.

  For example, when there are the above three target persons I, J, and K as target persons, the age information, sex information, and unit ID of the target persons I, J, and K are acquired as described above. Among the plurality of group singing history information stored in the group singing history database 3320, the age, sex, and unit of one registrant are the age “25 years” of the target person I, the sex “male”, and the unit Matches exactly “1”, and the age, gender, and unit of another registrant is exactly the same as the age “30”, sex “female”, and unit “2” of subject J. Whether there is group singing history information in which the age, sex, and unit of one of the registrants completely match the age “40 years”, sex “female”, and unit “3” of the subject K Is done.

  At this time, the age, sex, and unit of each of the plurality of registrants satisfy the first condition (that is, the age indicated by the age information of each of the acquired plurality of subjects, the sex indicated by the sex information, and the unit ID). If there is group singing history information (which completely matches the indicated unit), the host server 30 extracts the group singing history information. That is, in the extracted group singing history information, the singing history of a plurality of registrants corresponding to the same age, gender, and preference configuration of a plurality of subjects, in other words, Information on karaoke music pieces that have been selected in the past under the same age, sex, and preference structure as that of the subject's age, sex, and preference is included.

  For example, when there are the above three target persons I, J, and K as target persons, the age information, sex information, and unit ID of each of the target persons I, J, and K are acquired as described above. In the group singing history database 3320 shown in FIG. 3, a registrant (age: 25 years old, gender: male, unit: 1), user ID “user2” in the group singing history database 3320 shown in FIG. Group singing history information concerning a registrant (age: 30 years old, gender: female, unit: 2) and a registrant (age: 40 years old, gender: female, unit: 3) having a user ID “user3” That is, the group singing history information with the identification number “1” is extracted.

  On the other hand, the age, sex, and unit of each of the plurality of registrants satisfy the first condition (that is, the age indicated by the age information of each of the acquired plurality of subjects, the gender indicated by the sex information, and the unit ID) If there is no group singing history information that completely matches the unit, the host server 30 relaxes the first condition. For example, the first condition is relaxed to completely match the age and sex of each of the plurality of subjects. Alternatively, the first condition may be relaxed to completely match the age and unit of each of the plurality of subjects. Alternatively, the first condition may be relaxed so as to completely match the age of each of the plurality of subjects. Alternatively, the first condition may be relaxed to be included in a predetermined range of age of each of the plurality of subjects (for example, around 5 years old). Thereafter, the host server 30 performs the above determination again using the relaxed first condition. That is, among the plurality of group singing history information stored in the group singing history database 3320, the age, sex, and unit of each of the plurality of registrants satisfy the relaxed first condition (for example, the acquired plurality of singing history information). It is determined whether or not there is group singing history information, which is completely coincident with the age indicated by the age information of each target person and the gender indicated by the sex information. When there is group singing history information in which the age, sex, and unit of each of the plurality of registrants satisfy the first condition, the host server 30 extracts the group singing history information, and the group singing history information. If there is not, the first condition is relaxed, and the above determination is performed again using the relaxed first condition (or an error notification may be made that group singing history information could not be extracted) ).

  When the group singing history information is extracted, the host server 30 extracts the group singing history information (the age, gender, and preference of the plurality of subjects that satisfy the predetermined conditions regarding the age, sex, and preference configuration). Under the configuration, the recommended karaoke music to the operator is determined based on the information of past karaoke music selected in the past. In the present embodiment, among the karaoke songs related to the extracted group singing history information, the karaoke song whose evaluation result satisfies the second condition is determined as the karaoke song recommended for the operator. In this example, the second condition is set to be “3” or more. Accordingly, here, among the karaoke songs related to the extracted group singing history information, the karaoke song whose evaluation result is “3” or more is determined as the karaoke song recommended for the operator.

  Then, the host server 30 transmits (outputs) the determination result, that is, a display signal for displaying a search result screen including information related to the karaoke music recommended to the operator to the remote controller 20. As a result, the remote controller 20 displays a predetermined search result screen D1 (see FIG. 6 described later) on the display unit 26 based on the display signal received from the host server 30.

  FIG. 6 shows an example of the search result screen D1 displayed on the display unit 26 of the remote controller 20.

  In the search result screen D1 shown in FIG. 6, information related to a plurality of karaoke songs recommended to the operator (in this example, song names and singer names) is displayed in a list.

  At this time, information other than the song name and the singer name may be displayed as information related to a plurality of karaoke songs recommended to the operator. For example, in addition to the song name and singer name, information on the release date of the karaoke song, information indicating which operation companion is the karaoke song (for example, an image related to the operation companion), and for which age (generation) Information (for example, an image representing age (generation), etc.) indicating whether the karaoke piece is a karaoke piece may be displayed.

  Moreover, the arrangement | sequence aspect of the information of the some karaoke music recommended to an operator is not specifically limited. For example, the information of a plurality of karaoke songs recommended to the operator includes the order of the largest number of singing histories in the whole, the order of the number of singing histories in the operator's age (generation), the order of the highest evaluation results, Arrangements may be made in any arrangement mode such as the newest order of the singing history, the newest order of the release start year, etc. In addition, it may be possible to select (sort) by which the operator arranges in which arrangement mode. Moreover, it may be classified and displayed for men and women, classified and displayed for each age (generation), or classified and displayed for each operation companion.

  Hereinafter, a control procedure executed between the remote controller 20 and the host server 30 in order to realize the above method will be described with reference to FIG. In FIG. 7, each procedure is basically shown as a time series change from the upper side to the lower side in the drawing.

  In FIG. 7, the process shown in the flow on the remote controller 20 side is started when the software by the karaoke music piece recommendation program is activated.

  That is, when the operator performs a predetermined operation via the operation unit 25, the CPU of the control unit 21 of the remote controller 20 displays the search screen on the display unit 26 in step SA10.

  Thereafter, in step SA20, the CPU of the control unit 21 of the remote controller 20 stands by in a loop until a specific operation is performed via the operation unit 25 of the operator while the search screen is displayed on the display unit 26. When a specific operation is performed via the operation unit 25 of the operator (a specific operation is accepted), the process proceeds to step SA30. The procedure of step SA20 corresponds to an operation reception procedure, and the CPU 1 of the control unit 2 of the remote controller 20 that executes the procedure of step SA20 functions as an operation reception unit.
