Description

The present invention relates to a connected car for karaoke.

One of the problems facing an aging society is the theme of healthy life expectancy. Healthy life expectancy is the period during which one can live without any restrictions on daily life due to health problems. With the extension of average life expectancy in recent years, the increase in the difference between average life expectancy and healthy life expectancy (extension of the period during which one cannot live in good health) has become a problem. Therefore, along with the extension of average life expectancy, extension of healthy life expectancy is also required.

Here, it is said that exchanges and activities in the local community are effective for extending healthy life expectancy (see Non-Patent Document 1).

Karaoke singing is attracting attention as a means of interaction and activities in such local communities. For example, a business format such as karaoke snacks equipped with an online karaoke system was also called the "night market" in the karaoke business, but recently, stores are opened during the day to run karaoke classes and social gatherings for the elderly. Plays the role of.

By the way, in order to enjoy karaoke singing as part of exchanges and activities in the local community, users need to visit karaoke snacks in the neighborhood. On the other hand, some elderly people have difficulty traveling long distances due to physical problems. Such elderly people need to be picked up by their families or use public transportation. Therefore, it may be difficult for some elderly people to freely get the opportunity to sing karaoke. Furthermore, the owners of privately owned stores such as karaoke snacks are also aging, and the number of stores that are closing due to the absence of a successor is increasing, which is a major cause of the shrinking night market in the karaoke business. That is, since the number of stores such as karaoke snacks that the elderly visit is decreasing, the number of places where the elderly sing karaoke is decreasing.

(Reception department)
The reception unit 90a receives the music information of the reserved music that the user wishes to sing karaoke before the operation of the connected car 1 for karaoke starts.

The music information is identification information (music ID), music name, etc. set for each music. Music information can be accepted at any time before the start of operation. For example, the reception may be performed until just before the start of operation, or a predetermined time may be set in advance such as "until 17:00 the day before the usage day".

The number of reserved songs may be set to a predetermined number (up to 10 songs per user) in advance, and the number may not be particularly limited.

The user (or his / her family, etc.) inputs the music information of the reserved music via his / her own PC or mobile terminal. The reception unit 90a receives the input music information. The reception unit 90a outputs the received music information to the acquisition unit 90b. When the input of a plurality of music information is accepted, the reception unit 90a outputs the music information to the acquisition unit 90b in the order of acceptance.

In the present embodiment, the user shall input the music information together with the input of the usage date, the desired boarding time, and the desired disembarking time of the connected car 1 for karaoke by a set predetermined time, and the reception unit. 90a collectively accepts such information. The user may input the music information while confirming the confirmed operation schedule of the connected car 1 for karaoke. In this case, the reception unit 90a separately receives only the music information.

In addition, after inputting music information once, there may be a case where it is desired to add or change a reserved music due to a change in mood or the like. In that case, the user can add a new reserved music or delete a music already reserved before the operation starts. In this case, the extraction unit 90e performs a process of extracting the duplicate reserved music again, and the determination unit 90f performs a process of redetermining the performance start time of each reserved music including the duplicate reserved music (extraction process and determination). Details of the processing to be performed will be described later).

For users who do not want to sing karaoke (for example, users who want to talk with other users or who want to concentrate on listening to other people's karaoke songs), even if they do not enter music information. good.

(Acquisition department)
The acquisition unit 90b acquires the performance time of the reserved music based on the received music information.

For example, when the reception unit 90a outputs the music ID of the music M01, the acquisition unit 90b extracts the music ID matching the music ID from the music data stored in the karaoke device K, and the extracted music data. The playing time of the music M01 can be obtained from the attribute information included in. Alternatively, the acquisition unit 90b may acquire the performance time of the corresponding reserved music by referring to a table that defines the performance time for each music prepared in advance. The table is stored in, for example, the karaoke device K.

(Setting part)
The setting unit 90c sets a singing time zone that enables karaoke singing for each user based on the operation schedule.

The singing time zone is a time zone in which a user who gets on the connected car 1 for karaoke can actually sing karaoke. That is, it is a time zone immediately after boarding, excluding the vicinity of the time of disembarkation. For example, the setting unit 90c sets the singing start time after a predetermined time has elapsed from the boarding time of a certain user (for example, 5 minutes after the boarding time), and sets a predetermined time before the disembarking time (for example, 5 minutes before the disembarking time). The time zone to be the singing end time is set as the singing time zone of the user. An appropriate value (for example, 5 minutes) may be set in advance for the predetermined time, or it may be adjusted for each user according to the age, gender, etc. of the user. For example, older users tend to take longer to prepare for getting off. Therefore, the setting unit 90c can set 10 minutes before the disembarkation time as the singing end time. As described above, there may be a user who wants to get on the connected car 1 for karaoke but has not input the music information. In this case, the setting unit 90c does not set the singing time zone.

The singing time zone is set after the operation schedule is confirmed and the reception of reserved songs is completed. FIG. 5 is a diagram showing a singing time zone for each user set based on the operation schedule shown in FIG. 2, a reserved song for which each user wishes to sing karaoke, and an acquired performance time. For example, for user A, the singing time zone is 5 minutes after the boarding time 11:30 (11:35) as the singing start time and 5 minutes before the disembarking time 14:00 (13:55) as the singing end time. Is set. Further, the user A desires to sing two karaoke songs, the music M01 (playing time 4:20) and the music M02 (playing time 5:15). On the other hand, the singing time zone is not set for the user G who does not input the music information because he / she does not want to sing karaoke. The reserved songs shown in the example of FIG. 5 are arranged from the left in the order in which the user inputs the music information. For example, in FIG. 5, it is shown that the user B inputs the music information in the order of the music M03, M04, and M05.

(Split part)
The division unit 90d divides the set singing time zone of each user into a plurality of time zones according to the users who can sing karaoke.

Specifically, the division unit 90d first identifies the earliest singing start time and the latest singing end time from the singing time zones of all users, and sets the interval between them as the entire singing time zone. Then, the division unit 90d divides the entire singing time zone into a plurality of time zones for each time when the user who can sing karaoke changes.

For example, in the example of FIG. 5, the division unit 90d sets the singing start time of the user C, which is the earliest singing start time, at 11:05 and the singing end time of the user E, which is the latest singing end time, at 17:01. Identify and set as the entire singing time zone.

Then, the division unit 90d divides the entire singing time zone according to the time when the user who can sing karaoke changes. That is, as shown in FIG. 6, the divided portion 90d covers the entire singing time zone (11: 05-17: 01), and the time zone T01 (11: 05-11) in which only the user C can sing karaoke. : 10 for 5 minutes), time zone T02 (11: 10-11: 35 for 25 minutes) where only user C and user H can sing karaoke, user A, user C, and user H only Time zone T03 (60 minutes from 11:35 to 12:35) where karaoke singing is possible, time zone T04 (time zone T04 where only user A, user C, user F, and user H can sing karaoke (20 minutes from 12:35 to 12:55), time zone T05 (40 minutes from 12:55 to 13:35) where only user A, user C, and user F can sing karaoke, user A , Only user B, user C, and user F can sing karaoke at T06 (20 minutes from 13:35 to 13:55), only user B, user C, and user F can sing karaoke. Time zone T07 (13 minutes 13: 55-14: 08) when singing is possible, time zone T08 (14: 08-14: 28 minutes 20 minutes) when only user B and user F can sing karaoke ), User B, User E, Time zone T09 (37 minutes from 14:28 to 15:05) when only User B can sing karaoke, User B, User D, User E, Use Time zone T10 (20 minutes from 15:05 to 15:25) where only person F can sing karaoke, time zone T11 (15) where only user D, user E, and user F can sing karaoke. : 25-15: 37 for 12 minutes), time zone T12 (15: 37-16: 55 for 78 minutes) where only user D and user E can sing karaoke, and only user E can sing karaoke. Is possible to divide into 13 time zones of T13 (6 minutes of 16: 55-17: 01). More specifically, the start time (11:35, 13:35, 11:05, 15:05, 14:28, 12:35, 11:10) and the end of the 7 singing time zones shown in FIG. By arranging a total of 14 time information of the time (13:55, 15:25, 14:08, 16:55, 17:01, 15:37, 12:55) in the order of earliest (11:05, 11:10). , 11:35, 12:35, 12:55, 13:35, 13:55, 14:08, 14:28, 15:05, 15:25, 15:37, 16:55, 17:01), You can get 13 time zones. Then, a user who includes the time zone in the singing time zone is associated with each time zone.

(Extractor)
The extraction unit 90e extracts duplicate reserved music based on the received music information.

The duplicate reserved song is a reserved song in which a plurality of users desire to sing karaoke. After the reception of the music information of the reserved music is completed, the extraction unit 90e compares the music IDs included in the received music information, and extracts the music having the same music ID as the duplicate reserved music.

Among the reserved songs shown in the example of FIG. 5, in the music M02, the user A, the user C, and the user H desire to sing a karaoke song, and the music M04 is the user B, the user D, and the user. E wants to sing karaoke, user B and user C want to sing karaoke in music M05, and user C and user H want to sing karaoke in music M06. In the music M08 and the music M12, the user C and the user F desire to sing karaoke. That is, in the example of FIG. 5, the music M02, the music M04, the music M05, the music M06, the music M08, and the music M12 correspond to the duplicate reserved music. It should be noted that the duplicate reserved music can be extracted, for example, in the order of reception such as the date of use or the order of inputting the music information of the reserved music.

(Decision section)
The determination unit 90f determines the performance start time of the reserved music based on the performance time of the reserved music and the set singing time zone.

In the present embodiment, the determination unit 90f makes a duplicate reservation based on the performance time of the reserved song and the set singing time zone so that each user who desires to sing the karaoke of the duplicate reserved song can sing the karaoke together. Determine the start time of the song.

Next, the determination unit 90f determines whether or not the karaoke performance of the music M08 can be completed during the specified time zone T04, and whether or not the performance start time of the next reserved music is included in the time zone T04. Here, since the performance time of the music M08 is "6:20", the karaoke performance is ended during the time zone T04, and the performance start time (12:44:00) of the next reserved music is also the time zone T04. include.

Therefore, the determination unit 90f determines the performance start time of the music M08 as "12:35:00". In this case, the performance time of the music M08 is "12: 35: 00-12: 41: 20" (see FIG. 7).

(Music M12)
The determination unit 90f sets a time zone in which all users (user C and user F) who wish to sing karaoke of the music M12 can sing karaoke together from the time zone T01 to the time zone T13. Identify. As shown in FIG. 6, the time zone in which the user C and the user F can sing karaoke together is the time zone T04 (20 minutes from 12:35 to 12:55) and the time zone T05 (12 :). 55-13: 35 for 40 minutes), time zone T06 (13: 35-13: 55 for 20 minutes), and time zone T07 (13: 55-14: 08 for 13 minutes). Therefore, the determination unit 90f identifies the earliest time zone T04.

Here, in the time zone T04, the performance time (12: 35: 00-12: 41: 20) of the music M08 has already been determined.

Therefore, the determination unit 90f determines whether or not the karaoke performance of the music M12 can be completed within the remaining time of the specified time zone T04, and whether or not the performance start time of the next reserved music is included in the time zone T04. .. Here, since the performance time of the music M12 is "4:00", the karaoke performance is completed within the remaining time of the time zone T04 (11 minutes of 12: 44-12: 55), and the next reserved music is used. The performance start time (12:51:00) of is also included in the time zone T04.

Therefore, the determination unit 90f determines that the performance start time of the musical piece M12 is "12:44:00". In this case, the performance time of the music M12 is "12: 44: 00-12: 48: 00" (see FIG. 7).

2. 2. Determining the performance start time of the reserved music other than the duplicate reserved music After determining the performance start time of the duplicate reserved music, the determination unit 90f starts playing the remaining reserved music in order from the earliest time zone among the divided time zones. Determine the time.

(Time zone T01)
First, the determination unit 90f confirms the reserved music whose performance start time is undecided among the reserved music of the user C who can sing karaoke in 5 minutes of the time zone T01. At this point, among the reserved songs (10 songs) of the user C, 5 songs (songs M07, M09, M10, 5 songs of the songs M02, M05, M06, M08, and M12) are excluded. The performance start times of M11 and M13) are undecided.

The determination unit 90f determines whether or not the performance time of the reserved music excluding the duplicate reserved music is included in the time zone T01. Further, when there are a plurality of songs whose performance start time is undecided as in this example, the determination unit 90f determines whether or not the performance time of the reserved music is included in the time zone T01 in the order in which the music information of the reserved music is input, for example. To judge.

Here, for the reserved music excluding the duplicate reserved music, the playing time of the music M07 for which the music information is first input by the user C is "4:05". Therefore, although the karaoke performance can be ended during the time zone T01, the performance start time (11:12:00) of the next reserved music is included in the next time zone T02.

Therefore, the determination unit 90f ends the determination of the performance start time in the time zone T01, assuming that the performance start time cannot be determined within the time zone T01, that is, there is no music capable of karaoke performance in the time zone T01. Therefore, there is no music played in karaoke in the time zone T01 (see FIG. 8).

In this example, there are four reserved songs other than the song M07, excluding the duplicate reserved songs for which the user C wishes to sing karaoke. When there are a plurality of reserved songs for a certain user, the determination unit 90f may determine whether or not the performance start time can be set in the time zone T01 for each of the reserved songs. Further, whether or not the performance time of the reserved music is included in the time zone T01 is determined in a predetermined order (for example, the input order is from the last reserved information) regardless of the order in which the music information of the reserved music is input. It is possible to do it, or it may be done randomly without deciding a specific order.

(Time zone T02)
Next, the determination unit 90f confirms the reserved music whose performance start time is undecided among the reserved music of the user C and the user H who can sing karaoke in 25 minutes of the time zone T02. At this point, among the reserved songs (10 songs) of the user C, 5 songs (songs M07, M09, M10, 5 songs of the songs M02, M05, M06, M08, and M12) are excluded. The performance start times of M11 and M13) are undecided. Further, among the reserved songs (4 songs) of the user H, the performance start times of 2 songs (songs M24 and M25) excluding the duplicate reserved songs (2 songs of the songs M02 and M06) are undecided.

The determination unit 90f determines whether or not the performance time of the reserved music excluding the duplicate reserved music is included in the time zone T02. Further, when there are a plurality of users who can sing karaoke as in this example, the determination unit 90f determines, for example, the performance start time in order from the user who has the earliest input (reception) such as the date of use. As described above, in the present embodiment, the user C inputs the usage date and the like earlier than the user H. Therefore, the determination unit 90f determines whether or not the performance time of the reserved music is included in the time zone T02 in the order in which the music information is input for the reserved music of the user C.

Here, in the time zone T02, the performance time (11:10: 00-11: 15: 25) of the music M06 has already been determined.

Therefore, the determination unit 90f determines whether or not the performance start time of the reserved music excluding the duplicate reserved music can be determined in the remaining time zone (17 minutes from 11:18: 00-11: 35:00).

In this example, for the reserved music excluding the duplicate reserved music, the playing time of the music M07 for which the music information is first input by the user C is "4:05". Therefore, the karaoke performance is ended in the remaining time zone of the time zone T02, and the performance start time (11:25:00) of the next reserved music is also included in the time zone T02.

Therefore, the determination unit 90f determines that the performance start time of the musical piece M07 is "11:18:00". In this case, the performance time of the music M07 is "11:18: 00-11: 22: 05" (see FIG. 8).

The determination unit 90f subsequently determines whether or not the performance start time of the remaining reserved music can be determined during the time zone T02. Here, in the time zone T02, there are two users, user C and user H, who can sing karaoke. In this way, when there are a plurality of users who can sing karaoke in a certain time zone, if only one user continuously sings karaoke, other users cannot enjoy karaoke singing. Therefore, the determination unit 90f can determine the performance start time so that the reserved songs of the same user do not continue in excess of a predetermined number in the same time zone. The predetermined number is a value for determining the number of songs that one user can continuously sing karaoke, and is predetermined (for example, two songs).

In this example, it is assumed that the predetermined number is "2 songs". Therefore, since the reserved music of the user C is already two consecutive songs (music M06 and music M07) in the same time zone (time zone T02), the determination unit 90f determines the playing time of each reserved music of the user H. It is determined whether or not it is included in the time zone T02.

The determination unit 90f determines whether or not the performance start time of the remaining reserved music of the user H can be determined in the remaining time zone (10 minutes from 11:25: 00-11: 35:00).

In this example, for the reserved music excluding the duplicate reserved music, the playing time of the music M24 for which the music information is first input by the user H is “3:45”. Therefore, the karaoke performance is ended in the remaining time zone of the time zone T02, and the performance start time (11:31:00) of the next reserved music is also included in the time zone T02.

Therefore, the determination unit 90f determines that the performance start time of the music M24 is "11:25:00". In this case, the performance time of the music M24 is "11:25: 00-11: 28: 45" (see FIG. 8).

The determination unit 90f subsequently determines whether or not the performance start time of the remaining reserved music can be determined during the time zone T02.

Here, for the reserved music excluding the duplicate reserved music, the playing time of the music M25 for which the music information is input by the user H is "3:45". Therefore, the performance start time of the next reserved music is included in the next time zone T03. Therefore, the determination unit 90f ends the determination of the performance start time in the time zone T02.

(Time zone T03)
Next, the determination unit 90f confirms the reserved music whose performance start time is undecided among the reserved music of the user A, the user C, and the user H who can sing karaoke in 60 minutes of the time zone T03. At this point, the performance start time of one of the reserved songs (two songs) of the user A, excluding the duplicate reserved song (one of the songs M02), is undecided. Further, among the reserved songs (10 songs) of the user C, duplicate reserved songs (5 songs of songs M02, M05, M06, M08, and M12) and reserved songs whose performance start time has already been determined (song M07). The performance start times of four songs (M09, M10, M11, and M13) excluding one song) are undecided. In addition, among the reserved songs (4 songs) of the user H, the duplicate reserved songs (2 songs of the songs M02 and M06) and the reserved songs whose performance start time has already been determined (1 song of the song M24) are excluded. The performance start time of the song (music M25) is undecided.

The determination unit 90f determines whether or not the performance time of the remaining reserved music of the user A who has the earliest input (reception) such as the usage date is included in the time zone T03 among the users.

Here, in the time zone T03, the performance time (11:35: 00-11: 40: 15) of the music M02 has already been determined.

Therefore, the determination unit 90f determines whether or not the performance start time of the reserved music excluding the duplicate reserved music can be determined in the remaining time zone (52 minutes from 11:43:00 to 12:35:00).

In this example, for the remaining reserved music, the playing time of the music M01 for which the music information is input by the user A is "4:20". Therefore, the karaoke performance is ended in the remaining time zone of the time zone T03, and the performance start time (11:50:00) of the next reserved music is also included in the time zone T03.

Therefore, the determination unit 90f determines that the performance start time of the music M01 is "11:43:00". In this case, the performance time of the music M01 is "11:43: 00-11: 47: 20" (see FIG. 8). At this stage, the performance start time of all the reserved songs for which the user A wishes to sing karaoke is determined. That is, the user A can sing all the reserved songs in karaoke.

The determination unit 90f subsequently determines whether or not the performance start time of the reserved music can be determined during the time zone T03. In this example, the determination unit 90f determines whether or not the performance time of the reserved music of the user C, whose input (reception) such as the usage date is the earliest after the user A, is included in the time zone T03.

Here, the performance start time of the next reserved music is "11:50:00", and the performance time of the music M09 among the remaining reserved music of the user C is "5:05". Therefore, the karaoke performance is ended in the remaining time zone of the time zone T03, and the performance start time (11:58:00) of the next reserved music is also included in the time zone T03.

Therefore, the determination unit 90f determines that the performance start time of the musical piece M09 is "11:50:00". In this case, the performance time of the music M09 is "11: 50: 00-11: 55: 05" (see FIG. 8).

The determination unit 90f subsequently determines whether or not the playing time of the remaining reserved music of the user C is included in the time zone T03.

Here, the performance start time of the next reserved music is "11:58:00", and the playing time of the music M10 among the remaining reserved music of the user C is "4:15". Therefore, the karaoke performance is ended in the remaining time zone of the time zone T03, and the performance start time (12:05:00) of the next reserved music is also included in the time zone T03.

Therefore, the determination unit 90f determines that the performance start time of the musical piece M10 is "11:58:00". In this case, the performance time of the music M10 is "11: 58: 00-12: 02: 15" (see FIG. 8).

Here, since the reserved music of the user C is two consecutive songs (music M09 and music M10) in the same time zone (time zone T03), the determination unit 90f determines that the playing time of the remaining reserved music of the user H is the time zone. Determine if it is included in T03.

The performance start time of the next reserved music is "12:05: 00", and the performance time of the music M25, which is the remaining reserved music of the user H, is "3:45". Therefore, the karaoke performance is ended in the remaining time zone of the time zone T03, and the performance start time (12:11:00) of the next reserved music is also included in the time zone T03.

Therefore, the determination unit 90f determines the performance start time of the music M25 as "12:05: 00". In this case, the performance time of the music M25 is "12: 05: 00-12: 08: 45" (see FIG. 8). At this stage, the performance start time of all the reserved songs for which the user H wishes to sing karaoke is determined. That is, the user H can sing all the reserved songs in karaoke.

The determination unit 90f subsequently determines whether or not the playing time of the remaining reserved music of the user C is included in the time zone T03.

Here, the performance start time of the next reserved music is "12:11:00", and the playing time of the music M11 among the remaining reserved music of the user C is "5:55". Therefore, the karaoke performance is ended in the remaining time zone of the time zone T03, and the performance start time (12:19:00) of the next reserved music is also included in the time zone T03.

Therefore, the determination unit 90f determines that the performance start time of the musical piece M11 is "12:11: 00". In this case, the performance time of the music M11 is "12: 11: 00-12: 16: 55" (see FIG. 8).

The determination unit 90f subsequently determines whether or not the playing time of the remaining reserved music of the user C is included in the time zone T03.

Here, the performance start time of the next reserved music is "12:19:00", and the performance time of the music M13, which is the remaining reserved music of the user C, is "4:35". Therefore, the karaoke performance is ended in the remaining time zone of the time zone T03, and the performance start time (12:26:00) of the next reserved music is also included in the time zone T03.

Therefore, the determination unit 90f determines that the performance start time of the music M13 is "12:19:00". In this case, the performance time of the music M13 is "12: 19: 00-12: 23: 35" (see FIG. 8). At this stage, the performance start time of all the reserved songs for which the user C wishes to sing karaoke is determined. That is, the user C can sing all the reserved songs in karaoke. Further, since there is no reserved music whose performance start time is undecided in the time zone T03, the determination unit 90f ends the determination of the performance start time in the time zone T03.

(Time zone T04)
Next, the determination unit 90f selects the reserved music whose performance start time is undecided among the reserved music of the user A, the user C, the user F, and the user H who can sing karaoke for 20 minutes in the time zone T04. confirm. At this point, there are no reserved songs whose performance start times are undecided for user A, user C, and user H. On the other hand, among the reserved songs (4 songs) of the user F, the performance start times of the two songs (musics M22 and M23) excluding the duplicate reserved songs (two songs M08 and M12) are undecided.

The determination unit 90f determines whether or not the playing time of the remaining reserved music of the user F is included in the time zone T04.

Here, in the time zone T04, the performance time of the music M08 (12: 35: 00-12: 41: 20) and the performance time of the music M12 (12: 44: 00-12: 48: 00) have already been determined. are doing.

Therefore, the determination unit 90f determines whether or not the performance start time of the reserved music excluding the duplicate reserved music can be determined in the remaining time zone (4 minutes from 12:51:00 to 12:55:00).

In this example, the playing time of the music M22 for which the music information is input by the user F is "4:50". Therefore, since the karaoke performance cannot be ended in the remaining time zone of the time zone T04, the determination unit 90f ends the determination of the performance start time in the time zone T04.

(Time zone T05)
Next, the determination unit 90f confirms the reserved music whose performance start time is undecided among the reserved music of the user A, the user C, and the user F who can sing karaoke in 40 minutes of the time zone T05. At this point, there are no reserved songs whose performance start times are undecided for users A and C. On the other hand, among the reserved songs (4 songs) of the user F, the performance start times of the two songs (musics M22 and M23) excluding the duplicate reserved songs (two songs M08 and M12) are undecided.

The determination unit 90f determines whether or not the performance time of the remaining reserved music of the user F is included in the time zone T05.

Here, the playing time of the music M22 in which the music information is input by the user F is "4:50". Therefore, the karaoke performance is finished within the time zone T05, and the performance start time (13:02:00) of the next reserved music is also included in the time zone T05.

Therefore, the determination unit 90f determines that the performance start time of the music M22 is "12:55:00". In this case, the performance time of the music M22 is "12: 55: 00-12: 59: 50" (see FIG. 8).

The determination unit 90f subsequently determines whether or not the playing time of the remaining reserved music of the user F is included in the time zone T05.

Here, the performance start time of the next reserved music is "13:02:00", and the performance time of the music M23, which is the remaining reserved music of the user F, is "5:15". Therefore, the karaoke performance is ended in the remaining time zone of the time zone T05, and the performance start time (13:10: 00) of the next reserved music is also included in the time zone T05.

Therefore, the determination unit 90f determines that the performance start time of the music M23 is "13:02:00". In this case, the performance time of the music M23 is "13:02: 00-13: 07: 15" (see FIG. 8). At this stage, the performance start time of all the reserved songs for which the user F wishes to sing karaoke is determined. That is, the user F can sing all the reserved songs in karaoke. Further, since there is no reserved music whose performance start time is undecided in the time zone T05, the determination unit 90f ends the determination of the performance start time in the time zone T05.

(Time zone T06)
Next, the determination unit 90f selects the reserved music whose performance start time is undecided among the reserved music of the user A, the user B, the user C, and the user F who can sing karaoke for 20 minutes in the time zone T06. confirm. At this point, there are no reserved songs for which the performance start time is undecided for the user A, the user C, and the user F. On the other hand, among the reserved songs (3 songs) of the user B, the performance start time of one song (music M03) excluding the duplicate reserved songs (two songs M04 and M05) is undecided.

The determination unit 90f determines whether or not the playing time of the remaining reserved music of the user B is included in the time zone T06.

Here, in the time zone T06, the performance time of the music M05 has already been determined (13:35: 00-13: 39: 45).

Therefore, the determination unit 90f determines whether or not the performance start time of the reserved music excluding the duplicate reserved music can be determined in the remaining time zone (13 minutes from 13:42:00 to 13:55:00).

Here, the playing time of the music M03, which is the remaining reserved music of the user B, is "5:00". Therefore, the karaoke performance is finished within the time zone T06, and the performance start time (13:50:00) of the next reserved music is also included in the time zone T06.

Therefore, the determination unit 90f determines that the performance start time of the music M03 is "13:42:00". In this case, the performance time of the music M03 is "13:42:00 to 13:47:00" (see FIG. 8). At this stage, the performance start time of all the reserved songs for which the user B wishes to sing karaoke is determined. That is, the user B can sing all the reserved songs in karaoke. Further, since there is no reserved music whose performance start time is undecided in the time zone T06, the determination unit 90f ends the determination of the performance start time in the time zone T06.

(Time zone T07)
Next, the determination unit 90f confirms the reserved music whose performance start time is undecided among the reserved music of the user B, the user C, and the user F who can sing karaoke in 13 minutes of the time zone T07. At this point, none of User B, User C, and User F has a reserved song whose performance start time is undecided. Therefore, the determination unit 90f does not determine the performance start time for the time zone T07.

(Time zone T08)
Next, the determination unit 90f confirms the reserved music whose performance start time is undecided among the reserved music of the user B and the user F who can sing karaoke in 20 minutes of the time zone T08. At this point, neither user B nor user F has a reserved song whose performance start time is undecided. Therefore, the determination unit 90f does not determine the performance start time for the time zone T08.

(Time zone T09)
Next, the determination unit 90f confirms the reserved music whose performance start time is undecided among the reserved music of the user B, the user E, and the user F who can sing karaoke in 37 minutes of the time zone T09. At this point, there are no reserved songs for which the performance start time is undecided for the user B and the user F. On the other hand, among the reserved songs (8 songs) of the user E, the performance start times of 7 songs (songs M15, M16, M17, M18, M19, M20, M21) excluding the duplicate reserved songs (1 song of the song M04). Is undecided.

The determination unit 90f determines whether or not the playing time of the remaining reserved music of the user E is included in the time zone T09.

Here, the playing time of the music M15, which is the remaining reserved music of the user E, is "5:40". Therefore, the karaoke performance is finished within the time zone T09, and the performance start time (14:36:00) of the next reserved music is also included in the time zone T09.

Therefore, the determination unit 90f determines the performance start time of the music M15 as "14:28:00". In this case, the performance time of the music M15 is "14: 28: 00-14: 33: 40" (see FIG. 8).

The determination unit 90f continues to determine whether or not the playing time of the remaining reserved music of the user E is included in the time zone T09.

Here, the performance start time of the next reserved music is "14:36:00", and the performance time of the music M16, which is the remaining reserved music of the user E, is "4:50". Therefore, the karaoke performance is ended in the remaining time zone of the time zone T09, and the performance start time (14:43:00) of the next reserved music is also included in the time zone T09.

Therefore, the determination unit 90f determines the performance start time of the music M16 as "14:36:00". In this case, the performance time of the music M16 is "14: 36: 00-14: 40: 50" (see FIG. 8).

At this stage, there are two consecutive reserved songs of user E in the same time zone, and there is no reserved song whose performance start time is undecided among the reserved songs of other users. Therefore, the determination unit 90f determines whether or not a rest time during which the karaoke performance is not performed can be provided. The rest time is set to a predetermined time in advance. In this example, the fraction less than 1 minute for the performance end time of the reserved music is set to 0, and the time obtained by adding "10 minutes" is set as the rest time.

Here, the performance end time of the music M16 is "14:40:50". Therefore, a rest time can be provided within the remaining time of the time zone T09 (24 minutes and 10 seconds).

Therefore, the determination unit 90f determines the rest time from the performance end time (14:40:50) of the music M16 to 14:50:00 (see FIG. 8).

In this example, the number of songs for providing a rest time (predetermined number) and the number of songs that allow one user to continuously sing karaoke are described as the same, but these numbers are different. May be good. For example, the number of songs that one user can continuously sing karaoke may be "2 songs", and the number of songs for providing a rest time may be "3 songs". That is, after two reserved songs of one user are determined in succession in the same time zone, if there is a reserved song whose performance start time is undecided among the reserved songs of other users, the next use is another. Judgment is made based on the reserved music of the person. This is because, as described above, if only one user continuously sings karaoke, the other users cannot enjoy karaoke singing. On the other hand, if there is no reserved song whose performance start time is undecided among the reserved songs of other users after two songs reserved by one user are determined in succession in the same time zone, the next one is also the next one. Judgment is made based on the reserved music of the user. This is because it is not necessary to consider the karaoke singing of other users in the time zone. However, when the reserved music of one user is determined three times in a row, it is always determined whether or not to provide a rest time in consideration of the fatigue of one user.

After providing the rest time, the determination unit 90f continues to determine whether or not the performance time of the remaining reserved music of the user E is included in the time zone T09.

Here, the performance start time of the next reserved music is "14:50:00", and the performance time of the music M17, which is the remaining reserved music of the user E, is "4:10". Therefore, the karaoke performance is ended in the remaining time zone of the time zone T09, and the performance start time (14:57:00) of the next reserved music is also included in the time zone T09.

Therefore, the determination unit 90f determines that the performance start time of the musical piece M17 is "14:50:00". In this case, the performance time of the music M17 is "14: 50: 00-14: 54: 10" (see FIG. 8).

The determination unit 90f continues to determine whether or not the playing time of the remaining reserved music of the user E is included in the time zone T09.

Here, the performance start time of the next reserved music is "14:57:00", and the performance time of the music M18, which is the remaining reserved music of the user E, is "3:50". Therefore, the karaoke performance is ended in the remaining time zone of the time zone T09, and the performance start time (15:03:00) of the next reserved music is also included in the time zone T09.

Therefore, the determination unit 90f determines that the performance start time of the music M18 is "14:57:00". In this case, the performance time of the music M18 is "14: 57: 00-15: 00: 50" (see FIG. 8).

At this stage, the reserved music of the user E is two consecutive songs, and among the reserved music of other users, there is no reserved music whose performance start time is undecided. Therefore, the determination unit 90f determines whether or not a rest time during which the karaoke performance is not performed can be provided.

Here, the performance end time of the music M18 is "15:00:50". Therefore, it is not possible to provide a rest time within the remaining time (4 minutes and 10 seconds) of the time zone T09. In such a case, the determination unit 90f ends the determination of the performance start time in the time zone T09.

(Time zone T10)
Next, the determination unit 90f selects the reserved music whose performance start time is undecided among the reserved music of the user B, the user D, the user E, and the user F who can sing karaoke for 20 minutes in the time zone T10. confirm. At this point, there are no reserved songs for which the performance start time is undecided for the user B and the user F. On the other hand, the performance start time of one of the reserved songs (two songs) of the user D, excluding the duplicate reserved song (one of the songs M04), is undecided. Further, among the reserved songs (8 songs) of the user E, the duplicate reserved songs (1 song of the song M04) and the reserved songs whose performance start time has already been determined (4 songs of the songs M15, M16, M17, and M18). The performance start times of the three songs (music M19, M20, M21) excluding the above are undecided.

The determination unit 90f determines whether or not the playing time of the remaining reserved music of the user D who has the earliest input (reception) such as the usage date among the user D and the user E is included in the time zone T10.

Here, in the time zone T10, the performance time of the music M04 has already been determined (15:05: 00-15: 08: 55).

Therefore, the determination unit 90f determines whether or not the performance start time of the reserved music excluding the duplicate reserved music can be determined in the remaining time zone (14 minutes from 15: 11: 00-15: 25: 00).

The playing time of the music M14, which is the remaining reserved music of the user D, is "5:10". Therefore, the karaoke performance is finished within the time zone T10, and the performance start time (15:19:00) of the next reserved music is also included in the time zone T10.

Therefore, the determination unit 90f determines that the performance start time of the music M14 is “15:11: 00”. In this case, the performance time of the music M14 is "15: 11: 00-15: 16: 10" (see FIG. 8). At this stage, the performance start time of all the reserved songs for which the user D wishes to sing karaoke is determined. That is, the user D can sing all the reserved songs in karaoke.

The determination unit 90f subsequently determines whether or not the performance start time of the reserved music can be determined during the time zone T10. In this example, the determination unit 90f determines whether or not the performance time of the reserved music of the user E is included in the time zone T10.

Here, the performance start time of the next reserved music is "15:19:00", and the performance time of the music M19 among the remaining reserved music of the user E is "6:05". Therefore, the karaoke performance cannot be ended in the remaining time zone of the time zone T10.

In this case, the determination unit 90f ends the determination of the performance start time in the time zone T10.

(Time zone T11)
Next, the determination unit 90f confirms the reserved music whose performance start time is undecided among the reserved music of the user D, the user E, and the user F who can sing karaoke in the 12 minutes of the time zone T11. At this point, neither the user D nor the user F has a reserved music whose performance start time is undecided. On the other hand, among the reserved songs (8 songs) of the user E, the duplicate reserved songs (1 song of the song M04) and the reserved songs whose performance start time has already been determined (4 songs of the songs M15, M16, M17, and M18). The performance start times of the three songs (music M19, M20, M21) excluding the above are undecided.

The determination unit 90f determines whether or not the playing time of the remaining reserved music of the user E is included in the time zone T11.

Here, among the remaining reserved songs of the user E, the playing time of the song M19 is "6:05". Therefore, the karaoke performance is ended within the time zone T11, and the performance start time (15:34:00) of the next reserved music is also included in the time zone T11.

Therefore, the determination unit 90f determines that the performance start time of the music M19 is "15:25:00". In this case, the performance time of the music M19 is "15: 25: 00-15: 31: 05" (see FIG. 8).

The determination unit 90f continues to determine whether or not the playing time of the remaining reserved music of the user E is included in the time zone T11.

Here, the performance start time of the next reserved music is "15:34:00", and the playing time of the music M20 among the remaining reserved music of the user E is "5:40". Therefore, the karaoke performance cannot be ended in the remaining time zone of the time zone T11.

In this case, the determination unit 90f ends the determination of the performance start time in the time zone T11.

(Time zone T12)
Next, the determination unit 90f confirms the reserved music whose performance start time is undecided among the reserved music of the user D and the user E who can sing karaoke in 78 minutes of the time zone T12. At this point, there is no reserved music whose performance start time is undecided for user D. On the other hand, among the reserved songs (8 songs) of the user E, 5 of the duplicate reserved songs (1 song of the song M04) and the reserved songs (songs M15, M16, M17, M18, M19) whose performance start time has already been determined. The performance start times of the two songs (songs M20 and M21) excluding the song) are undecided.

The determination unit 90f determines whether or not the playing time of the remaining reserved music of the user E is included in the time zone T12.

Here, among the remaining reserved songs of the user E, the playing time of the song M20 is "5:40". Therefore, the karaoke performance is ended within the time zone T12, and the performance start time (15:45:00) of the next reserved music is also included in the time zone T12.

Therefore, the determination unit 90f determines that the performance start time of the music M20 is "15:37:00". In this case, the performance time of the music M20 is "15: 37: 00-15: 42: 40" (see FIG. 8).

The determination unit 90f continues to determine whether or not the playing time of the remaining reserved music of the user E is included in the time zone T12.

Here, the playing time of the music M21, which is the remaining reserved music of the user E, is "4:55". Therefore, the karaoke performance is ended within the time zone T12, and the performance start time (15:52:00) of the next reserved music is also included in the time zone T12.

Therefore, the determination unit 90f determines that the performance start time of the music M21 is "15:45:00". In this case, the performance time of the music M21 is "15: 45: 00-15: 49: 55" (see FIG. 8). At this stage, the performance start time of all the reserved songs for which the user E wishes to sing karaoke is determined. That is, the user E can sing all the reserved songs in karaoke. Further, since there is no reserved music whose performance start time is undecided in the time zone T12, the determination unit 90f ends the determination of the performance start time in the time zone T12.

It is not necessary to determine whether or not two reserved songs of the same user are consecutive for each time zone. In this case, the determination unit 90f may determine, for example, whether or not two reserved songs that are not duplicate reserved songs of the same user are consecutive. More specifically, from the time zone T11 to the time zone T12, there are two consecutive reserved songs that are not duplicate reserved songs of user E, and among the reserved songs of other users, the reserved songs whose performance start time is undecided. not exist. Therefore, the determination unit 90f determines whether or not a rest time during which the karaoke performance is not performed can be provided. Here, the performance end time of the music M20 is "15:42:40". Therefore, a rest time can be provided within the remaining time of the time zone T12 (73 minutes and 20 seconds). Therefore, the determination unit 90f determines the rest time from the performance end time (15:42:40) of the music M20 to 15:52:00.

(Time zone T13)
As described above, the performance start time is determined for all the reserved songs of the user A to the user H who use the connected car 1 for karaoke on the usage day X. Therefore, the determination unit 90f does not determine the performance start time for the time zone T13.

The determination unit 90f stores the information (performance timetable) of the performance start time and the break time of the determined reserved music in the storage unit 60.

When the usage day X is reached, the karaoke connected car 1 travels based on the operation schedule and picks up and drops the user. In this case, the computer device C provides the karaoke device K with a performance timetable of the usage date X stored in the storage unit 60. The karaoke device K automatically performs the karaoke performance of the reserved music based on the reserved music and the performance start time shown in the performance timetable.

== Processing in a connected car for karaoke ==
Next, a specific example of the processing in the karaoke connected car 1 will be described with reference to FIG. FIG. 9 is a flowchart showing a processing example in the karaoke connected car 1.

The reception unit 90a receives the music information of the reserved music that the user wishes to sing karaoke before the operation of the connected car 1 for karaoke starts (reception of the reserved music, step 10).

The acquisition unit 90b acquires the performance time of the reserved music based on the music information received in step 10 (acquisition of the performance time. Step 11).

The setting unit 90c sets a singing time zone that enables karaoke singing for each user based on the operation schedule (setting of the singing time zone. Step 12).

The division unit 90d divides the singing time zone of each user set in step 12 into a plurality of time zones according to the users who can sing karaoke (divided into a plurality of time zones. Step 13).

Based on the music information received in step 10, the extraction unit 90e extracts duplicate reserved music, which is a reserved music for which a plurality of users desire to sing karaoke, for each time zone divided in step 13 (duplicate reservation). Extraction of music. Step 14).

The determination unit 90f starts playing the duplicate reserved music for each of a plurality of time zones divided in step 13 based on the playing time of the reserved music acquired in step 11 and the singing time zone set in step 12. Determine the time (determine the performance start time of the duplicate reserved music. Step 15).

After step 15, the determination unit 90f determines the performance start time of the reserved music other than the duplicate reserved music for each of the plurality of time zones divided in step 13 (determines the performance start time of the remaining reserved music). 16).

After that, when the day of use of the karaoke connected car 1 comes, the computer device C controls the running of the karaoke connected car 1 based on the operation schedule, and picks up and drops each user (based on the operation schedule). Running. Step 17).

At that time, the karaoke device K performs the karaoke performance of the reserved music based on the performance start time determined in steps 15 and 16 (karaoke performance based on the performance start time. Step 18).

As described above, the connected car 1 for karaoke according to the present embodiment is equipped with a karaoke device K for performing karaoke performance in the car, and travels based on an operation schedule in which the boarding time and the disembarking time of the user are set. Control. The connected car 1 for karaoke acquires the playing time of the reserved music based on the reception unit 90a that receives the music information of the reserved music that the user wishes to sing karaoke before the start of operation. A reservation in which a plurality of users desire to sing karaoke based on the unit 90b, the setting unit 90c that sets the singing time zone that enables karaoke singing for each user based on the operation schedule, and the received music information. Based on the playing time of the reserved music and the set singing time zone so that the extraction unit 90e that extracts the duplicate reserved music that is the music and each user who wants to sing the karaoke of the duplicate reserved music can sing the karaoke together. It also has a determination unit 90f for determining the performance start time of the duplicate reserved music.

According to such a connected car 1 for karaoke, it is possible to determine one performance start time as a duplicate reserved song for a song that a plurality of users desire to sing karaoke. Therefore, the same song is not repeatedly played in karaoke while riding. That is, according to the karaoke connected car 1 according to the present embodiment, each user can get on the car without getting bored. Further, by determining one performance start time for the duplicate reserved music, it is possible to obtain many opportunities to karaoke the other reserved music. That is, each user can enjoy karaoke singing by effectively utilizing the limited boarding time.

Further, the connected car 1 for karaoke according to the present embodiment has a division unit 90d that divides the set singing time zone of each user into a plurality of time zones according to the user who can sing karaoke. The extraction unit 90e extracts duplicate reserved music for each of a plurality of divided time zones, and the determination unit 90f determines the performance start time of the duplicate reserved music, and then determines the duplicated reserved music for each of the divided time zones. Determine the performance start time of reserved songs other than reserved songs. By dividing the singing time zone into a plurality of time zones in this way, the performance start time of the reserved music can be determined for each time zone. Further, by determining the performance start time of the duplicate reserved music in advance, it is possible to preferentially perform the karaoke performance of the music that the plurality of users want to perform the karaoke singing.

<Modification 1>
The process of determining the performance start time of the reserved music including the duplicate reserved music is not limited to the above example. For example, the configuration may be such that the division portion 90d is not provided.

Specifically, the determination unit 90f selects the reserved songs one by one in order from the user's reserved song with the earliest input (reception) of the usage date, etc., based on the playing time of the reserved song and the set singing time zone. The performance start time can be determined.

At this time, when the determination unit 90f determines the performance start time T of the reserved music M of one user, the reserved music M is a duplicate reserved music extracted by the extraction unit 90e, and the reserved music M is reserved. If the other user can sing a karaoke song at the performance start time of the reserved music M, the reserved music M of the other user is also determined as the performance start time T.

For example, in the example of the above embodiment, the reserved music of the user A who inputs the usage date and the like earliest is two music (music M01 and M02).

Here, the performance time of the music M01 is "4:20", the karaoke performance is ended during the singing time zone (11: 35-13: 55) of the user A, and the performance of the next reserved music is started. The time (11:42:00) is also included in the singing time zone of the user A.

Therefore, the determination unit 90f determines that the performance start time of the music M01 is "11:35:00". In this case, the performance time of the music M01 is "11:35: 00-11: 39: 20".

Next, the reserved music of the user B whose input of the usage date and the like is the earliest after the user A is three songs (musics M03, M04, M05).

Here, the performance time of the music M03 is "5:00", the karaoke performance is ended during the singing time zone (13: 35-15: 25) of the user B, and the performance of the next reserved music is started. The time (13:43:00) is also included in the singing time zone of user B.

Therefore, the determination unit 90f determines the performance start time of the music M03 as "13:35:00". In this case, the performance time of the music M03 is "13: 35: 00-13: 40: 00".

Next, the reserved music of the user C whose input such as the usage date is the earliest after the user B is 10 songs (musics M02, M05, M06, M07, M08, M09, M10, M11, M12, M13).

In the singing time zone 11: 05-14: 08 of the user C, the performance time of the music M01 is "11: 35: 00-11: 39: 20", and the performance time of the music M03 is "13: 35: 00-". 13:40:00 "has been decided. Therefore, the determination unit 90f is in a time zone that does not overlap with the time in which the performance time has already been determined among the singing time zones of the user C (remaining time zones "11: 05-11: 35", "11:42". -13: 35 "," 13: 43-14: 08 ", but the predetermined interval after the end of the karaoke performance of the song has already been excluded, the same shall apply hereinafter), and the karaoke performance ends, and the performance start time of the next reserved song Determines if there is a song included in the singing time zone of user C.

Here, the performance time of the music M02 is "5:15", the karaoke performance is finished during the remaining time zone (11: 05-11: 35) of the user C, and the performance of the next reserved music is performed. The start time (11:13:00) is also included in the remaining time zone of user B.

Therefore, the determination unit 90f can determine the performance start time of the music M02 as "11:05: 00". In this case, the performance time of the music M02 is "11:05: 00-11: 10: 15".

By the way, as described in the above embodiment, the music M02 corresponds to the duplicate reserved music that the user A, the user C and the user H desire to sing karaoke. However, the singing time zone of the user A is "11: 35-13: 55", and the singing time zone of the user H is "11: 10-12: 55". In such a case, the user A and the user H cannot sing the karaoke song of the music M02 together with the user C.

Next, the reserved music of the user D whose input of the usage date and the like is the earliest after the user C is two songs (music M04 and M14).

Here, the performance time of the music M04 is "3:55", the karaoke performance is ended during the singing time zone (15: 05-16: 55) of the user D, and the performance of the next reserved music is started. The time (15:11:00) is also included in the singing time zone of the user D.

Therefore, the determination unit 90f determines that the performance start time of the music M04 is "15:05: 00". In this case, the performance time of the music M04 is "15: 05: 00-15: 08: 55".

By the way, the music M04 corresponds to a duplicate reserved music in which the user B, the user D, and the user E desire to sing karaoke. On the other hand, the singing time zone of the user B is "13: 35-15: 25", and the singing time zone of the user E is "14: 28-17: 01". In such a case, the user B and the user E can sing the karaoke song of the music M04 together with the user D.

In this case, the determination unit 90f also determines the performance start time of the music M04 as "15:05: 00" for the user B and the user E.

Next, among the reserved songs of the user E whose input of the usage date etc. is the earliest after the user D, the reserved songs whose performance start time is undecided are 7 songs (musics M15, M16, M17, M18, M19, M20, M21).

In the singing time zone (14: 28-17: 01) of the user E, "15:05: 00-15: 08: 55" is determined as the performance time of the music M04. Therefore, the determination unit 90f uses a time zone (remaining time zones "14: 28-15: 05", "15:11") that does not overlap with the time in which the performance time has already been determined among the singing time zones of the user E. -17: 01 ”), it is determined whether or not there is a song in which the karaoke performance is finished and the performance start time of the next reserved song is included in the singing time zone of the user E.

Here, the performance time of the music M15 is "5:40", the karaoke performance is finished during the remaining time zone (14: 28-15: 05) of the user E, and the performance of the next reserved music is performed. The start time (14:36:00) is also included in the remaining time zone of user E.

Therefore, the determination unit 90f can determine the performance start time of the music M15 as "14:28:00". In this case, the performance time of the music M15 is "14: 28: 00-14: 33: 40".

Next, the reserved music of the user F, whose input of the usage date and the like is the earliest after the user E, is four songs (music M08, M12, M22, M23).

In the singing time zone "12: 35-15: 37" of the user F, "13: 35: 00-13: 40: 00" is determined as the performance time of the music M03, and the performance time of the music M04 is determined. "15:05: 00-15: 08: 55" has been determined, and "14: 28: 00-14: 33: 40" has been determined as the performance time of the music M15. Therefore, the determination unit 90f is in a time zone that does not overlap with the time in which the performance time has already been determined among the singing time zones of the user F (remaining time zones "12: 35-13: 35", "13:43". -14: 28 "," 14: 36-15: 05 "," 15: 11-15: 37 "), the karaoke performance ends, and the performance start time of the next reserved song is the singing time zone of user F. Determine if there are any songs included in.

Here, the performance time of the music M08 is "6:20", the karaoke performance is finished during the remaining time zone (12: 35-13: 35) of the user F, and the performance of the next reserved music is performed. The start time (12:44:00) is also included in the remaining time zone of the user F.

Therefore, the determination unit 90f can determine the performance start time of the music M08 as "12:35:00". In this case, the performance time of the music M08 is "12: 35: 00-12: 41: 20".

By the way, the music M08 corresponds to a duplicate reserved music that the user C and the user F desire to sing karaoke. On the other hand, the singing time zone of the user C is "11: 05-14: 08". In such a case, the user C can sing the karaoke song of the music M08 together with the user F.

In this case, the determination unit 90f also determines the performance start time of the music M08 as "12:35:00" for the user C.

Next, the reserved music of the user H whose input of the usage date and the like is the latest is four music (music M02, M06, M24, M25).

In the singing time zone "11: 10-12: 55" of the user H, "11: 35: 00-11: 39: 20" is determined as the performance time of the music M01, and the performance time of the music M02 is determined. "11:05: 00-11: 10: 15" has been determined, and "12: 35: 00-12: 41: 20" has been determined as the performance time of the music M08. Therefore, the determination unit 90f is in a time zone that does not overlap with the time in which the performance time has already been determined among the singing time zones of the user H (remaining time zones "11: 13-11: 35", "11:42". -12: 35 "," 12: 44-12: 55 "), it is determined whether or not there is a song in which the karaoke performance ends and the performance start time of the next reserved song is included in the singing time zone of the user H. do.

Here, the performance time of the music M02 is "5:15", the karaoke performance is finished during the remaining time zone (11: 13-11: 35) of the user H, and the performance of the next reserved music is performed. The start time (11:21:00) is also included in the remaining time zone of the user H.

Therefore, the determination unit 90f can determine the performance start time of the music M02 as "11:13:00". In this case, the performance time of the music M02 is "11:13: 00-11: 18: 15".

By the way, the music M02 corresponds to a duplicate reserved music in which the user A, the user C, and the user H desire to sing karaoke. On the other hand, the singing time zone of the user A is "11: 35-13: 55". Further, for the user C, the performance time of the music M02 has already been determined. In such a case, the user A and the user C cannot sing the karaoke song of the music M02 together with the user H.

The determination unit 90f repeats the above processing in the order in which the input of the usage date and the like is earlier until the performance start time of the reserved music of all the users is determined. As described above, even if the division unit 90d is not provided, one performance start time can be set for at least a part of the duplicate reserved music.

<Second Embodiment>
Next, with reference to FIG. 10, the connected car for karaoke according to the second embodiment will be described. A detailed description of the same configuration as that of the first embodiment will be omitted.

Some users of connected cars for karaoke do not like singing karaoke with other users. The present embodiment describes an example in which the performance start time of the reserved music is determined according to the wishes of such a user.

(Reception department)
The reception unit 90a according to the present embodiment receives chorus availability information together with music information. The chorus possibility information is information indicating whether or not the reserved music is karaoke sung together with other users.

The user (or his / her family, etc.) inputs chorus availability information together with the music information of the reserved music via his / her own PC or mobile terminal. The reception unit 90a outputs the input chorus permission / rejection information to the extraction unit 90e.

(Extractor)
The extraction unit 90e according to the present embodiment extracts duplicate reserved songs based on the chorus possibility / non-chorus information.

For example, in the example of FIG. 5, the reception unit 90a receives chorus permission / rejection information from user C to the effect that “the chorus with another user is refused”, and the other user “with another user”. It is assumed that the chorus permission / rejection information to the effect that "chorus is allowed" is accepted (see FIG. 10).

In this case, the extraction unit 90e does not compare the music ID included in the music information received from the user C with the music ID included in the music information received from another user.

Therefore, the duplicate reserved music in the example of FIG. 5 is two music, music M02 (user A and user H) and music M04 (user B, user D, and user E).

(Decision section)
The determination unit 90f determines the performance start time of the duplicate reserved music as in the first embodiment. For example, the determination unit 90f is a user (user A and the user) whose chorus propriety information is "possible" among all the users who desire the karaoke singing of the music M02 from the time zone T01 to the time zone T13. Person H) specifies the time zone during which the karaoke singing can be performed together. As shown in FIG. 6, the time zone in which the user A and the user H can sing karaoke together is the time zone T03 (60 minutes from 11:35 to 12:35) and the time zone T04 (12: 35-12: 55 for 20 minutes). Therefore, the determination unit 90f identifies the earliest time zone T03.

Here, since the performance time of the music M02 is "5:15", the karaoke performance is ended during the time zone T03, and the performance start time (11:43:00) of the next reserved music is also the time zone T03. include.

Therefore, the determination unit 90f determines that the performance start time of the music M02 is "11:35:00". In this case, the performance time of the music M02 is "11:35: 00-11: 40: 15". Similarly, the performance time of the music M04 is "15: 05: 00-15: 08: 55".

The determination unit 90f determines the performance start time for the duplicate reserved music M02 and the music M04, and then the performance start time for the remaining reserved music (including the music M02 for which the user C wishes to sing karaoke alone). To decide.

As described above, the reception unit 90a of the connected car 1 for karaoke according to the present embodiment receives and extracts the chorus possibility information indicating whether or not the reserved music is sung together with other users, together with the music information. The unit 90e extracts duplicate reserved songs based on the chorus possibility / non-chorus information.

In this way, by extracting duplicate reserved songs based on the chorus availability information received for each user, it is possible to meet the wishes of users who want to enjoy karaoke singing alone.

<Modification 2>
The chorus permission / rejection information may be set for each reserved song. In this case, the reception unit 90a receives chorus availability information for each reserved song.

For example, in the example of FIG. 5, the reception unit 90a receives chorus possibility information from the user C to the effect that the chorus of the music M02, M05, M06, and M07 is "possible to chorus with other users", and the music M08. , M09, M10, M11, M12, M13 accept chorus permission information to the effect that "chorus with other users is refused", and other users "chorus with other users" for all songs. Is accepted (see FIG. 11).

In this case, among the music information received from the user C, the extraction unit 90e has the music IDs of the music M08, M09, M10, M11, M12, and M13 included in the music information received from other users. Do not compare with ID.

Therefore, the duplicate reserved music in the example of FIG. 5 includes music M02 (user A, user C and user H), music M04 (user B, user D and user E), and music M05 (user B). And user C) and music M06 (user C and user H).
