(Acquisition department)
The acquisition unit 200 acquires user identification information of a user who sings karaoke. The user identification information is information unique to each user, such as a user ID for identifying the user.

For example, suppose user U uses the karaoke device K. In this case, the user U inputs his / her own user ID and password via the remote controller device 50. The karaoke device K transmits the input user ID and password to the server device S as a login request. The server device S logs in the user U to the karaoke system 1 by storing the user ID of the user in the storage means 60 (described later) based on the login request of the user U received from the karaoke device K. Complete.

After that, it is assumed that the user U selects the music X via the remote controller 50. In this case, the karaoke device K reserves the music X by registering the music ID of the music X and the user ID of the selected user U in the reservation queue.

When the performance order of the music X is reached, the karaoke device K reads the music data of the music X from the storage means 10a based on the music ID of the music X, and starts the karaoke performance based on the accompaniment data included in the music data. ..

At this time, the acquisition unit 200 acquires the user ID of the user U who sings the karaoke of the music X from the reservation queue.

(Display control unit)
The display control unit 300 performs various display controls on the karaoke device K.

When the predetermined timing data associated with the user identification information of the user is stored, the display control unit 300 according to the present embodiment changes the display color of the lyrics telop based on the predetermined timing data. ..

The predetermined timing data is the timing data transmitted from the server device S. When the karaoke device K receives the predetermined timing data from the server device S, the karaoke device K stores the predetermined timing data in the storage means 10a. The details of the predetermined timing data will be described later.

For example, the display control unit 300 causes the display device 30 to display the lyrics telop based on the lyrics telop data of the music X as the karaoke performance of the music X progresses.

Here, it is assumed that when the user U sings the karaoke of the music X, the storage means 10a stores the predetermined timing data associated with the user ID of the user U.

In this case, the display control unit 300 changes the display color of the lyrics telop based on the predetermined timing data as the karaoke performance of the music X progresses. A known method can be used for the process of changing the display color of the lyrics telop.

On the other hand, when the predetermined timing data is not stored, the display control unit 300 according to the present embodiment lyric telop based on one timing data selected from a plurality of timing data stored in the data storage unit 100. Change the display color of.

There are various criteria for selecting one timing data. For example, the display control unit 300 may randomly select one from a plurality of timing data each time. Alternatively, the display control unit 300 may select a plurality of timing data stored in the data storage unit 100 in a predetermined order. For example, when the above-mentioned eight types of timing data are stored in the data storage unit 100, the display control unit 300 selects the timing data of 30 msec for the first karaoke performance, and for the next karaoke performance. May select timing data of 60 msec, and select timing data in order such as ...

Here, it is assumed that when the user U sings the karaoke of the music X, the storage means 10a does not store the predetermined timing data associated with the user ID of the user U.

In this case, the display control unit 300 changes the display color of the lyrics telop based on the selected timing data as the karaoke performance of the music X progresses. For example, the display control unit 300 selects one timing data (here, the timing data is 150 msec) from eight types of timing data, and changes the display color of the lyrics telop based on the timing data. Specifically, the display control unit 300 changes the display color of one phrase included in the lyrics telop of the displayed song X at a timing 150 msec ahead of the timing at which the phrase should be sung in karaoke.

The user U sings the karaoke of the song X while referring to the lyrics telop.

(Evaluation department)
The evaluation unit 400 evaluates the karaoke singing performed by the user.

A known method can be used for evaluation of karaoke singing. For example, when the user U sings the karaoke of the music X, the evaluation unit 400 compares the singing audio signal based on the karaoke singing of the user U with the reference data of the music X, and according to the degree of matching. Find the scoring value. The scoring value can be obtained, for example, by a numerical value with a maximum of 100 points.

The evaluation unit 400 in the present embodiment evaluates the karaoke singing regardless of whether or not the user desires it. Further, the evaluation of the karaoke singing is performed at least until a predetermined timing data is received from the server device S.

(Transmission processing unit)
When the predetermined timing data is not stored, the transmission processing unit 500 refers to the one timing data and the lyrics telop whose display color is changed based on the one timing data, and performs the karaoke singing. The evaluation and the user identification information of the user are linked and transmitted to the server device S as aggregated information.

For example, it is assumed that the user U sings the karaoke song of the music X while referring to the lyrics telop whose display color is changed based on the timing data of 150 msec when the predetermined timing data is not stored. Then, as a result, it is assumed that the evaluation unit 400 requests an evaluation of 87.0 points. In this case, the transmission processing unit 500 associates the timing data of 150 msec, the evaluation of karaoke singing (87.0 points), and the user ID of the user U, and transmits the aggregated information AI to the server device S.

At least until the predetermined timing data is received from the server device S, the transmission processing unit 500 transmits the aggregated information to the server device S each time the user U sings a karaoke song.

== Server device ==
The server device S is a computer that manages and processes various types of information. FIG. 4 is a diagram showing the configuration of the server device S. The server device S includes a storage means 60, a communication means 70, and a control means 80. Each configuration is connected to bus B via an interface (not shown).

[Memory means]
The storage means 60 is a large-capacity storage device that stores various types of data. In the present embodiment, the storage means 60 stores the aggregated information acquired from the karaoke device K for each user.

FIG. 5A is a diagram showing aggregated information of the user U stored in the storage means 60. As shown in FIG. 5A, the storage means 60 stores the number of times the karaoke singing is performed (the number of singing times, that is, the number of the received aggregated information) and the average value of the evaluations for each of the eight types of timing data. .. The storage means 60 may store other statistical values (median value, etc.) instead of the average value of the evaluations, or may store only the highest evaluation (for example, the highest score).

[Communication means]
The communication means 70 provides an interface for communicating with the karaoke device K.

[Control means]
The control means 80 performs various controls on the server device S. The control means 80 includes a CPU and a memory (neither of which is shown). The CPU realizes various functions by executing a program stored in the memory.

In the present embodiment, the control means 80 functions as the storage processing unit 80a and the determination unit 80b by executing the program stored in the memory by the CPU.

(Memory processing unit)
The storage processing unit 80a stores the aggregated information received from the karaoke device K for each user.

For example, in a state where the aggregated information of the user U shown in FIG. 5A is stored in the storage means 60, the server device S sends the aggregated information AI (timing data of 150 msec, evaluation of karaoke singing “87. It is assumed that "0 points" and the user ID of the user U) are received.

In this case, the storage processing unit 80a updates the number of singing times corresponding to the timing data of 150 msec from 7 times to 8 times, and adds "87.0 points" to the average value of the evaluation (88.1 points). Update to. FIG. 5B shows the aggregated information AI added to the aggregated information of the user U in FIG. 5A.

(Decision part)
When the aggregated information including the user identification information of the user satisfies the predetermined condition, the determination unit 80b determines the predetermined timing data based on the aggregated information, and the predetermined timing data is used by the user of the user. It is linked with the identification information and transmitted to the karaoke device K.

The predetermined condition is a reference for starting the process of determining the predetermined timing data, and is set in advance. The predetermined conditions are, for example, the number of aggregated information (40 or more, etc.) and the period (after 3 months have passed since the aggregated information was first stored, etc.). The predetermined timing data is at least one of the timing data included in the aggregated information of a certain user stored in the storage means 60, which indicates the optimum timing for changing the display color for the certain user.

For example, it is assumed that the predetermined condition is set as "the number of aggregated information is 40 or more". In this case, in the state of FIG. 5B, the aggregated information including the user ID of the user U satisfies the predetermined condition. Therefore, the determination unit 80b determines predetermined timing data based on the aggregated information shown in FIG. 5B.

The determination of predetermined timing data can be made using various criteria. For example, the determination unit 80b can determine predetermined timing data based on the average value of evaluations corresponding to each timing data. When the average value of the evaluation corresponding to a certain timing data is higher than the average value of the evaluation corresponding to another timing data, the user U is changed by changing the display color of the lyrics telop based on the timing indicated by the certain timing data. It can be considered that was easy to sing karaoke (as a result, the evaluation was high).

In the example of FIG. 5B, the timing data corresponding to the highest evaluation average value is the timing data of 120 msec. Therefore, the determination unit 80b determines the timing data of 120 msec as the predetermined timing data PT.

Then, the determination unit 80b transmits the determined predetermined timing data PT to the karaoke device K in association with the user ID of the user U. The storage means 10a of the karaoke device K stores the received predetermined timing data PT in association with the user ID of the user U.

After that, when the user U sings a karaoke song on the karaoke device K, the display control unit 300 of the karaoke device K changes the display color of the lyrics telop based on the predetermined timing data PT.

== Processing in the karaoke system ==

Similar to the first modification, the acquisition unit 200 in this modification acquires the music identification information of a certain song in which the user sings karaoke, in addition to the user identification information of the user who sings karaoke.

(Correction part)
The correction unit 600 corrects the evaluation of the karaoke singing of a certain song by the evaluation unit 400 according to the difficulty level associated with the song identification information of the certain song.

The difficulty level is set for each song. The difficulty level is included in the attribute information of the music data, for example. Difficulty is the difficulty of singing a song in karaoke. In general, it is difficult to sing karaoke for songs with high pitches and fast tempos. Therefore, a high degree of difficulty is set for such a song. The difficulty level can be classified into, for example, "difficult", "somewhat difficult", "normal", "somewhat easy", and "easy".

Corrections according to the difficulty level can be made in various ways. For example, a correction value according to the difficulty level is set in advance. As a specific example, when the difficulty level is "difficult", "somewhat difficult", "normal", "somewhat easy", and "easy", the correction values are "+5.0 points", "+2.5 points", and " It can be "± 0 points", "-2.5 points", and "-5.0 points". The correction unit 600 corrects the evaluation by using the correction value according to the difficulty level.

Here, it is assumed that as a result of the user U singing the karaoke of the music X, the evaluation unit 400 evaluates it as "88.0 points". Further, it is assumed that the difficulty level of the music X is "somewhat difficult".

In this case, the correction unit 600 sets the evaluation "88.0 points" of the karaoke song of the music X to the correction value "+2.5 points" corresponding to the difficulty level "slightly difficult" associated with the music ID of the music X. It is corrected according to the above, and "90.5 points" is obtained.

The transmission processing unit 500 associates the corrected evaluation with the user ID and the like, and transmits the corrected evaluation to the server device S as aggregated information.

According to such a karaoke system 1, predetermined timing data suitable for the user can be determined regardless of the difficulty level of each song. The correction unit 600 may be provided on the server device S side.
