<Embodiment>
A karaoke device according to an embodiment will be described with reference to FIGS.

==Karaoke Equipment==
The karaoke machine K is a device for playing karaoke music and for users to sing karaoke. Each karaoke machine K is assigned with device identification information. The device identification information is information unique to each karaoke machine, such as a device ID for identifying the karaoke machine.

As shown in FIG. 1, the karaoke device K includes a karaoke unit 10, a speaker 20, a display device 30, a microphone 40, and a remote control device 50.

The karaoke machine main unit 10 performs various controls related to karaoke performance and singing, such as controlling the karaoke performance of the selected song, displaying lyrics and background images, and processing audio signals input through the microphone 40. The speaker 20 is configured to emit sound based on the sound emission signal from the karaoke machine main unit 10. The display device 30 is configured to display videos and images on a screen based on the signal from the karaoke machine main unit 10. The microphone 40 is configured to convert the user's singing voice into an analog audio signal and input it to the karaoke machine main unit 10. The remote control device 50 is a device for performing various operations on the karaoke machine main unit 10.

As shown in FIG. 2, the karaoke machine 10 according to this embodiment includes a storage unit 10a, a communication unit 10b, an input unit 10c, a performance unit 10d, and a control unit 10e. Each component is connected to a bus B via an interface (not shown).

[Storage means]
The storage unit 10a is a large-capacity storage device that stores various types of data, including music data.

Song data is assigned song identification information to identify each song. Song identification information is information unique to each song, such as a song ID used to identify the song. Song data includes accompaniment data, reference data, etc. Accompaniment data is data that forms the basis of the karaoke performance sound. Reference data is data that indicates the main melody of the song being performed karaoke.

The storage means 10a stores lyric caption data for displaying lyric captions corresponding to each song on the display device 30 or the like in sync with the karaoke performance, background image data to be displayed on the display device 30 or the like during the karaoke performance, and song attribute information.

In this embodiment, the storage means 10a pre-stores the conditions for performing karaoke. The conditions for performing karaoke are stored, for example, in the form of a table that associates condition identification information, condition names, and specific content of the conditions. Condition identification information is information unique to each condition, such as a condition ID for identifying the condition. Condition names are names assigned to each condition. The specific content of the conditions is information used when determining whether the conditions are met (described below).

Figure 3 is an example of a conditions table. In this example, the conditions shown are "solo karaoke," "scored content," "couples," and "just one song."

"Solo Karaoke" is a condition suitable for songs that the user wants to sing or songs that the user is currently practicing. "Scoring Content" is a condition suitable for songs that the user is good at or songs that are expected to get high scores in scoring content. "Couple" is a condition suitable for duet songs or songs that the user wants to play for the opposite sex. "Just one song" is a condition suitable for songs that everyone knows or songs that will liven up the atmosphere.

As shown in FIG. 3, the "solo karaoke" condition is associated with a condition ID ***C1, a condition name "solo karaoke," and specific content "only one user ID obtained in the operation input to log in to the karaoke device." The "scoring content" condition is associated with a condition ID ***C2, a condition name "scoring content," and specific content "scoring content currently being performed." The "couple" condition is associated with a condition ID ***C3, a condition name "couple," and specific content "two user IDs obtained in the operation input to log in to the karaoke device, the users being of different genders, and the age difference being less than 12 years." The "just one song" condition is associated with a condition ID ***C4, a condition name "just one song," and specific content "five minutes have passed without any karaoke performance."

Note that the specific content of the conditions mentioned above is merely an example. For example, the specific content of the age difference in the "couple" condition could be "under 6 years old," and the specific content of the elapsed time in the "one song for now" condition could be "3 minutes."

[Communication means/input means]
The communication means 10b provides an interface for communication with the remote control device 50. The input means 10c is configured to allow the user to input various operations. The input means 10c is a button or the like provided on the karaoke machine main unit 10. Alternatively, the remote control device 50 may function as the input means 10c.

[Means of performance]
The performance means 10d, under the control of the control means 10e, performs karaoke performance of music pieces and processes signals based on singing voices input through the microphone 40. The performance means 10d includes a sound source, a mixer, an amplifier, etc. (none of which are shown).

[Control means]
The control means 10e performs various controls on the karaoke device K. The control means 10e includes a CPU and a memory (neither of which is shown). The CPU executes programs stored in the memory to realize various functions.

In this embodiment, the CPU executes the programs stored in the memory, causing the control means 10e to function as a setting unit 100, a registration unit 200, a determination unit 300, and a reservation unit 400.

(Settings section)
The setting section 100 sets conditions for performing karaoke for the music piece selected by the user.

When using karaoke device K, the user operates remote control device 50 and inputs their own user identification information. User identification information is information unique to each user, such as a user ID used to identify the user.

The karaoke device K completes the user's login to the karaoke device K by storing the entered user identification information in the storage means 10a (i.e., by performing the login process).

A user who has logged in to karaoke device K operates remote control device 50 to select list registration mode. List registration mode is a mode for registering songs selected by the user to a list. The user then operates remote control device 50 to select the songs they wish to register to the list. Song selection can be done in the same way as when selecting songs they wish to sing karaoke.

Here, the setting unit 100 according to this embodiment sets the conditions based on operational input from the user.

Specifically, when a user selects a song, the setting unit 100 displays a list of settable conditions, for example, on the display screen of the remote control device 50.

The user operates the remote control device 50 and selects from the displayed conditions the conditions they believe are suitable for the selected song.

The setting unit 100 sets the conditions selected by the user as the conditions for performing karaoke of the selected song. Note that the user may select multiple conditions for one song. In this case, the setting unit 100 sets the selected multiple conditions as the conditions for performing karaoke of the selected song.

(Registration Department)
The registration unit 200 associates the song identification information of the selected song with the condition identification information of the set condition, and registers them in the user's list.

When the setting unit 100 sets conditions, the registration unit 200 associates the condition ID of the set conditions with the song ID of the selected song and registers them in the list. Registration in the list is performed each time the user selects a song (each time a condition is set).

The list is linked to the user ID and stored in the storage means 10a. It is also possible to add new songs to a list created in the past. Previously created lists may be stored in the storage means 10a, or may be stored in a server device (not shown) separate from the karaoke device K.

For example, karaoke machine K transmits the user ID of the logged-in user to the server device. The server device reads the list linked to the received user ID from the storage means and transmits it to karaoke machine K. The registration unit 200 links the song ID of the newly selected song and the condition ID of the conditions set for that song to the received list, and registers them in order to update the list. The updated list is transmitted to and stored in the server device, for example, when the user logs out.

(Judgment Department)
The determining unit 300 determines at a predetermined timing whether the condition corresponding to the condition identification information registered in the list of the user is satisfied.

The predetermined timing is any timing while the user is using the karaoke machine. For example, the predetermined timing can be a single timing, such as the timing when the login process is performed based on the user's operational input, or 30 minutes after the login process. Alternatively, multiple timings can be set as the predetermined timing. For example, the predetermined timing can be the timing when the login process is performed based on the user's operational input, or 20 minutes after the login process.

When the specified timing arrives, the determination unit 300 determines whether the condition corresponding to the condition ID registered in the user's list is met (i.e., whether the specific content of the condition is met).

If it is determined that a certain condition is met, the determination unit 300 outputs the condition ID of that condition to the reservation unit 400.

(Reservation Department)
If it is determined that the condition is met, the reservation unit 400 registers the song identification information linked to the condition identification information of the condition in a reservation queue, thereby reserving the song corresponding to the song identification information.

When the determination unit 300 outputs a condition ID for a certain condition (i.e., when it is determined that a certain condition is met), the reservation unit 400 refers to the list and identifies the song ID associated with the condition ID for the certain condition. The reservation unit 400 reserves the song corresponding to the identified song ID by registering the identified song ID in a reservation queue. Note that when there are multiple song IDs associated with a certain condition ID, the reservation unit 400 may register all of those song IDs in the reservation queue, or may register only one song ID in the reservation queue.

==Operation of Karaoke Device K==
Next, a specific example of the operation of the karaoke machine K in this embodiment will be described with reference to Figures 4A to 5. Figure 4A is a flowchart showing the process of registering to the list (i.e., an example of the operation of the setting unit 100 and the registration unit 200). Figure 4B is a flowchart showing the process of registering to the reservation queue (i.e., an example of the operation of the determination unit 300 and the reservation unit 400). Figure 5 is an example of a list of user U1 stored in the storage means 10a. In this example, it is assumed that user U1 will be using the karaoke machine K. It is also assumed that the process of registering to the list and the process of registering to the reservation queue are performed at different times (for example, on different days).

[Processing when registering to the list]
User U1 operates the remote control device 50 to input his/her own user ID. The karaoke device K stores the input user ID of user U1 in the storage means 10a, thereby completing the login of user U1 to the karaoke device K (login process, step 10).

User U1 operates remote control device 50 to select list registration mode. User U1 then operates remote control device 50 to select the song they wish to register in the list (select song; step 11).

The setting unit 100 sets the conditions for performing karaoke for the song selected by user U1 in step 11 (setting the conditions for the selected song; step 12).

The registration unit 200 links the song ID of the song selected by user U1 in step 11 with the condition ID of the condition set in step 12 and registers it in user U1's list (the song ID and condition ID are linked and registered in the list; step 13).

Karaoke device K repeats steps 11 to 13 until user U1 logs out (if Y in step 14).

As a specific example, user U1 operates remote control device 50 to select song X1. The setting unit 100 displays a list of conditions that can be set as conditions for performing karaoke of song X1 on the display screen of remote control device 50. In this example, four conditions (see Figure 3) are displayed: "Solo karaoke," "Scored content," "Couple," and "Just one song."

The user selects the "solo karaoke" condition from the four conditions that they believe is most suitable for song X1 (an example of operational input).

Based on user U1's selection, the setting unit 100 sets the condition for song X1 to "solo karaoke." The registration unit 200 links song X1's song ID ***X1 with the "solo karaoke" condition ID ***C1 and registers them in user U1's list.

Next, user U1 operates remote control device 50 to select song X2. From the four conditions, user U1 selects the "scoring content" condition that they believe is most suitable for song X2 (an example of operational input).

Based on user U1's selection, the setting unit 100 sets the condition for song X2 to "scoring content." The registration unit 200 associates song X2's song ID ***X2 with the condition ID ***C2 for "scoring content," and registers them in user U1's list.

Next, user U1 operates remote control device 50 to select song X3. From the four conditions, user U1 selects the condition "Couple" that they believe is most suitable for song X3 (an example of operational input).

Based on user U1's selection, the setting unit 100 sets the condition for song X3 to "Couple." The registration unit 200 links song X3's song ID ***X3 with the condition ID ***C3 of "Couple," and registers them in user U1's list.

Next, user U1 operates remote control device 50 to select song X4. From the four conditions, user U1 selects the condition "One song for now" that they believe is most suitable for song X4 (an example of operational input).

Based on user U1's selection, the setting unit 100 sets the condition for song X4 to "One song for now." The registration unit 200 links song X4's song ID ***X4 with the condition ID ***C4 for "One song for now," and registers them in user U1's list.

By repeating this process, the list for user U1 shown in Figure 5 is completed. Note that, like song X3 and song X5, there may be songs in one list that are linked to the same condition ID.

[Processing when joining a reservation queue]
User U1 operates the remote control device 50 to input his/her own user ID. The karaoke device K stores the input user ID of user U1 in the storage means 10a, thereby completing the login of user U1 to the karaoke device K (login process, step 20). After user U1 has logged in, the karaoke device K reads out a list of user U1 from the storage means 10a.

At a predetermined timing, the determination unit 300 determines whether the condition corresponding to the condition ID registered in the list for user U1 is satisfied (determines whether the condition corresponding to the condition ID registered in the list is satisfied; step 21).

If it is determined in step 21 that the condition is met (Y in step 22), the reservation unit 400 reserves the song corresponding to the song ID by registering the song ID linked to the condition ID of that condition in the reservation queue (registering the song ID linked to the condition ID in the reservation queue; step 23).

(Specific Example 1)
For example, when the time arrives when the login process is performed based on user U1's operation input (an example of a predetermined time), the judgment unit 300 judges whether the condition of "solo karaoke" corresponding to the condition ID ***C1 registered in user U1's list is satisfied.

As shown in Figure 3, the specific content of "solo karaoke" is "only one user ID was acquired in the operational input to log in to the karaoke device." The determination unit 300 determines whether one user ID has been stored in the storage means 10a through the login process (i.e., whether one user is logged in).

In this example, only user U1 is logged in to karaoke device K. Therefore, the determination unit 300 determines that the condition for "solo karaoke" is met. In this case, the determination unit 300 outputs the condition ID ***C1 for "solo karaoke" to the reservation unit 400.

The reservation unit 400 references the list for user U1 shown in Figure 5 and reserves song X1 by registering song ID ***X1 of song X1, which is linked to condition ID ***C1 of "solo karaoke," in the reservation queue.

Furthermore, when condition IDs corresponding to multiple conditions are registered, as in the list for user U1 shown in Figure 5, the judgment unit 300 performs judgment processing for each condition.

In the above example, the determination unit 300 determines for each condition whether the conditions corresponding to the condition IDs other than condition ID ***C1 (ID ***C2, ID ***C3, ID ***4) registered in user U1's list are satisfied.

As shown in Figure 3, the specific content of "Scoring Content" is "Scoring Content Currently Being Executed." The determination unit 300 determines whether scoring content is being executed on the karaoke device K.

In this example, the specified timing for performing the determination process is the timing when the login process is performed based on user U1's operation input. In other words, user U1 has just logged in to karaoke device K and has not yet used any graded content. Therefore, the determination unit 300 determines that the condition for the "graded content" is not met. In this case, the determination unit 300 does not output the condition ID ***C2 for the "graded content" to the reservation unit 400.

As shown in Figure 3, the specific content of a "couple" is "two user IDs obtained through operational input to log in to the karaoke device, the users are of different genders, and the age difference is less than 12 years." The determination unit 300 determines whether there are two user IDs stored in the storage means 10a through the login process (i.e., whether there are two users logged in).

In this example, only user U1 is logged in to karaoke device K. Therefore, the determination unit 300 determines that the "couple" condition is not met. In this case, the determination unit 300 does not output the "couple" condition ID ***C3 to the reservation unit 400.

As shown in Figure 3, the specific content of "one song for now" is "five minutes have passed without any karaoke performance of a song." The determination unit 300 determines whether five minutes or more have passed without any karaoke performance of a song.

In this example, the predetermined timing for performing the determination process is the timing when the login process is performed based on user U1's operation input. In other words, user U1 has just logged in to karaoke device K. Therefore, the determination unit 300 determines that the condition for "one song for now" is not met. In this case, the determination unit 300 does not output the condition ID ***C4 for "one song for now" to the reservation unit 400.

In this way, in specific example 1, the reservation unit 400 only reserves song X1.

(Specific Example 2)
On the other hand, suppose that the predetermined timing is 30 minutes after the login process based on the operation input of user U1. Also, suppose that at that time, no other users are logged in to karaoke machine K except user U1, the scoring content is not being played, and user U1 stops singing karaoke 20 minutes after the login process.

In this case, the determination unit 300 determines whether the conditions corresponding to each condition ID registered in user U1's list are met.

As shown in Figure 3, the specific content of "solo karaoke" is "only one user ID was acquired in the operational input to log in to the karaoke device." The determination unit 300 determines whether one user ID has been stored in the storage means 10a through the login process (i.e., whether one user is logged in).

In this example, only user U1 is logged in to karaoke device K. Therefore, the determination unit 300 determines that the condition for "solo karaoke" is met. In this case, the determination unit 300 outputs the condition ID ***C1 for "solo karaoke" to the reservation unit 400.

The reservation unit 400 references the list for user U1 shown in Figure 5 and reserves song X1 by registering song ID ***X1 of song X1, which is linked to condition ID ***C1 of "solo karaoke," in the reservation queue.

In addition, the determination unit 300 determines for each condition whether the conditions corresponding to condition IDs other than condition ID ***C1 (ID ***C2, ID ***C3, ID ***4) registered in user U1's list are satisfied.

As mentioned above, no scoring content is being performed at the specified timing. Furthermore, only user U1 is logged in to karaoke machine K.

Therefore, the determination unit 300 determines that the conditions for "scored content" and "couple" are not met. In this case, the determination unit 300 does not output the condition ID ***C2 for "scored content" and the condition ID ***C3 for "couple" to the reservation unit 400.

As shown in Figure 3, the specific content of "one song for now" is "five minutes have passed without any song being played by karaoke." The determination unit 300 determines whether five minutes or more have passed without any song being reserved.

In this example, the predetermined timing for performing the determination process is 30 minutes after the login process based on user U1's operation input. However, user U1 stops singing karaoke 20 minutes after the login process. In other words, at the predetermined timing, no karaoke performance has been performed for 10 minutes. Therefore, the determination unit 300 determines that the condition of "one song for now" is met. In this case, the determination unit 300 outputs the condition ID ***C4 for "one song for now" to the reservation unit 400.

The reservation unit 400 references the list for user U1 shown in Figure 5 and reserves song X4 by registering song ID ***X4 of song X1, which is linked to condition ID ***C4 of "One song for now," in the reservation queue.

In this way, in specific example 2, the reservation unit 400 makes reservations for songs X1 and X4.

(Specific Example 3)
Alternatively, the predetermined timing may be the timing at which the login process based on the operation input of user U1 is performed, or 20 minutes after the login process. Furthermore, it is assumed that 20 minutes later, there is no other user other than user U1 logged in to the karaoke machine K, and the scoring content is being played.

In this case, the determination unit 300 first determines whether the conditions corresponding to each condition ID registered in user U1's list are satisfied when the login process is performed based on user U1's operation input. At this time, song X1 is reserved, as described in Specific Example 1.

Next, the determination unit 300 determines whether the conditions corresponding to each condition ID registered in user U1's list are satisfied 20 minutes after the login process based on user U1's operation input is performed.

As shown in Figure 3, the specific content of "Scoring Content" is "Scoring Content Currently Being Executed." The determination unit 300 determines whether scoring content is being executed on the karaoke device K.

In this example, the scoring content is being implemented at the specified timing. Therefore, the determination unit 300 determines that the condition for the "scoring content" is met. In this case, the determination unit 300 outputs the condition ID ***C2 for the "scoring content" to the reservation unit 400.

The reservation unit 400 references the list for user U1 shown in Figure 5 and reserves song X2 by registering song ID ***X2 of song X2, which is linked to condition ID ***C2 of the "scored content," in the reservation queue.

The determination unit 300 also determines whether the conditions corresponding to the condition IDs other than condition ID ***C2 (ID ***C1, ID ***C3, ID ***4) registered in user U1's list are satisfied for each condition.

As mentioned above, at this point, only user U1 is logged in to karaoke device K, and since the scoring content is being performed, five minutes have not passed without a song being played karaoke.

Therefore, the determination unit 300 determines that the conditions of "Couple" and "One song for now" are not met. In this case, the determination unit 300 does not output the condition ID ***C3 for "Couple" and the condition ID ***C4 for "One song for now" to the reservation unit 400.

In this way, in specific example 3, the reservation unit 400 makes reservations for songs X1 and X2.

In specific example 3, song X1 corresponding to condition ID ***C1 for "solo karaoke" has already been reserved 20 minutes after the login process. In such a case, the reservation unit 400 may or may not make a duplicate reservation for song X1 20 minutes after the login process. Alternatively, the reservation unit 400 may make a new reservation for song X1 only if the previously reserved song X1 is already being performed as a karaoke performance 20 minutes after the login process.

==Summary==
As is clear from the above, the karaoke device K of this embodiment includes a setting unit 100 that sets conditions for performing karaoke for a song selected by the user; a registration unit 200 that links the song identification information of the selected song with the condition identification information of the set conditions and registers them in the user's list; a determination unit 300 that determines whether the condition corresponding to the condition identification information registered in the user's list is satisfied at a predetermined time while the user is using the karaoke device; and a reservation unit 400 that, if it is determined that the condition is satisfied, registers the song identification information linked to the condition identification information of the condition in a reservation queue, thereby reserving the song corresponding to the song identification information.

With this karaoke device K, users can set conditions for performing karaoke on songs they have selected and then register them in a list. Furthermore, if the karaoke device K determines at a predetermined time that a condition corresponding to the condition identification information registered in the user's list is met, it can automatically register the song identification information linked to the condition identification information of that condition in the reservation queue. Therefore, simply by setting conditions for performing karaoke on songs they have selected, users can have the opportunity to perform karaoke on songs registered in their list. In other words, the karaoke device K of this embodiment can provide users with the opportunity to perform karaoke on songs registered in their list.

In addition, the determination unit 300 according to this embodiment can make a determination at the timing when login processing is performed based on user input. In this case, it becomes possible to reserve music that is appropriate at the timing when login processing is performed.

In addition, the setting unit 100 according to this embodiment can set conditions based on operational input from the user. In this case, the user can set conditions that they deem appropriate for each song.

<Modification 1>
If there are multiple predetermined timings, a song that is determined to satisfy the condition at one timing may be determined not to satisfy the condition at another timing. In such a case, the determination unit 300 can instruct the reservation unit 400 to delete the song identification information registered in the reservation queue.

For example, at a certain point in time, the reservation unit 400 reserves song X1 by registering song ID ***X1 of song X1, which is linked to condition ID ***C1 of "solo karaoke," in the reservation queue.

Suppose that user U2 then logs in to karaoke machine K at a different time before the karaoke performance of song X1. Furthermore, user U2 is of a different gender than user U1, but the same age.

As shown in Figure 3, the specific details of a "couple" are "two user IDs obtained through operational input to log in to the karaoke device, the users are of different genders, and the age difference is less than 12 years." The determination unit 300 determines whether two user IDs are stored in the storage means 10a through the login process (i.e., whether there are two logged-in users), whether the users are of different genders, and whether the age difference is less than 12 years. The gender and age of the users can be identified from the user's attribute information (described below).

In this example, two users, user U1 and user U2, are logged in to karaoke device K. Furthermore, user U1 and user U2 are of different genders but the same age. Therefore, the determination unit 300 determines that the condition for "couple" is met. In this case, the determination unit 300 outputs the condition ID ***C3 for "couple" to the reservation unit 400.

The reservation unit 400 references the list for user U1 shown in Figure 5 and registers the song ID ***X3 of song X3 and the song ID ***X5 of song X5, which are linked to the condition ID ***C3 of "couple," in the reservation queue, thereby reserving song X3 and song X5.

However, because there are now two users, the determination unit 300 determines that the condition for "solo karaoke" is not met. In this case, the determination unit 300 instructs the reservation unit 400 to delete the song ID of song X1 registered in the reservation queue. The reservation unit 400 checks the reservation queue, and if song ID ***X1 for song X1 is registered, deletes song ID ***X1.

In this way, with the configuration of this modified example, it is possible to reserve only songs that meet the appropriate conditions at the time the specified timing arrives. If the specified timing is the timing at which login processing is performed based on the user's operational input, the determination unit 300 may determine whether the conditions corresponding to each condition ID registered in user U2's list are satisfied at the timing at which login processing is performed based on user U2's operational input.

<Modification 2>
In the above embodiment, the setting unit 100 sets the conditions based on the user's operation input. On the other hand, the setting unit 100 can also set the conditions based on at least one of the user's attribute information, the user's singing history, and the log information of the karaoke machine.

In this modified example, the storage means 10a stores user attribute information, the user's singing history, and karaoke machine log information. The attribute information, singing history, and log information may be stored in the storage means 10a, or may be stored in a server device (not shown) separate from the karaoke machine K.

User attribute information is personal information about the user, such as the user's name, age, and gender. The user's singing history is information obtained when the user uses a karaoke device, such as the song IDs of songs the user has previously sung, the date and time the karaoke was sung, the results of using the scoring content (e.g., the score), and the device ID of the karaoke device used. The user's attribute information and singing history are linked to user identification information.

The log information of a karaoke device includes an operation history that chronologically records user inputs, and an operation history that chronologically records the processes actually performed in response to the inputs. The log information is linked to the device ID.

For example, the setting unit 100 can calculate a score for each condition using the user's attribute information, the user's singing history, and the karaoke machine's log information, and set the condition with the highest score as the condition for performing the karaoke version of the selected song.

As a specific example, assume that user U1 operates remote control device 50 to select song X1. In this example, it is possible to set four conditions (see the embodiment for details): "Solo karaoke," "Scored content," "Couple," and "Just one song."

The setting unit 100 extracts the combination of the date and time when song X1 was sung by user U1 and the device ID of the karaoke device used from the singing history stored in the storage means 10a.

Based on the extracted combination of date and time and device ID and log information, the setting unit 100 identifies the users who were logged in to the karaoke device corresponding to the device ID on that date and time. If only user U1 was logged in, the setting unit 100 adds "+1" to the "solo karaoke" score.

On the other hand, if only one other user other than user U1 is logged in, the setting unit 100 determines the gender and age difference between user U1 and the other user based on the attribute information of each of user U1 and the other user. If the genders are different and the age difference is less than 12 years, the setting unit 100 adds "+1" to the "couple" score.

The setting unit 100 also references user U1's singing history and checks whether the results of using the scored content are linked to the extracted combination of date, time, and device ID. If the results of using the scored content are linked, the setting unit 100 adds "+1" to the score of the "scored content."

The setting unit 100 also checks, based on the extracted combination of date and time and device ID and the log information, whether there is a record of a karaoke performance on the karaoke device corresponding to that device ID within five minutes prior to that date and time. If there is no record of a karaoke performance, the setting unit 100 adds "+1" to the score of the "Just One Song."

After performing the above process, the setting unit 100 sets the condition with the highest score as the condition for performing karaoke for song X1.

In the above example, if user U1 has sung song X1 karaoke multiple times (i.e., if there are multiple singing histories for song X1), the setting unit 100 can extract multiple combinations of the date and time the karaoke performance was performed and the device ID of the karaoke device used. In this case, the setting unit 100 can add up the scores for each condition obtained based on each combination, and set the condition with the highest total score as the condition for performing karaoke for song X1.

The setting unit 100 may also set conditions using at least one of the user's attribute information, the user's singing history, and the karaoke machine's log information.

In this way, the setting unit 100 in this modified example can set conditions based on at least one of the user's attribute information, the user's singing history, and the karaoke machine's log information. With this configuration, conditions appropriate for the song can be automatically set without the user having to select conditions.

The setting unit 100 may set conditions for a single song based on user input and conditions based on at least one of the user's attribute information, the user's singing history, and the karaoke machine's log information. In this case, multiple condition IDs are linked to the song ID of a single song and registered in the list. In this case, if the determination unit 300 determines that either or both conditions are met, it outputs the condition ID of the condition to the reservation unit 400.

Furthermore, as described in the embodiment, when a user selects a song, the setting unit 100 displays a list of settable conditions on the display screen of the remote control device 50. Thereafter, it is assumed that the user does not select a condition from the displayed conditions within a certain period of time (for example, within three minutes). In such a case, the setting unit 100 may set a condition based on at least one of the user's attribute information, the user's singing history, and the karaoke device's log information.

<Modification 3>
The setting unit 100 can also set conditions other than those described in the embodiment. For example, conditions such as "family,""friends," and "workplace" can be set. "Family" is a condition suitable for family-oriented songs, anime songs, etc. "Friends" is a condition suitable for songs in a genre that has common tastes, songs that are popular among people of the same generation, etc. "Workplace" is a condition suitable for songs that even older users know, songs that are not too good (for example, songs that can sing just the chorus at karaoke), etc.

Specific conditions for "family" can be, for example, "three or more user IDs obtained through operational input to log in to the karaoke machine, users with the same last name, and including users who are elementary school age or younger." Specific conditions for "friends" can be, for example, "three or more user IDs obtained through operational input to log in to the karaoke machine, and the age difference is less than three years." Specific conditions for "workplace" can be, for example, "three or more user IDs obtained through operational input to log in to the karaoke machine, and the age difference is 10 years or more."
