The identification unit 100 identifies a candidate song based on the received singing history. The candidate song can be identified by various methods. For example, the specific unit 100 sets a predetermined number of times in advance, and obtains the number of times sung for each song included in the singing history. The specific unit 100 specifies as a candidate song a song for which the number of times obtained is equal to or greater than a predetermined number of times. Further, the specifying unit 100 may specify a predetermined number of songs as candidate songs in order from the one with the largest number of requests. Alternatively, when there are a plurality of logged-in users, the specific unit 100 may specify a song common to each user's singing history as a candidate song.

(Detection unit)
The detection unit 200 detects a keyword related to a word in the lyrics of the candidate song based on the keyword included in the keyword information transmitted from the user terminal and the lyrics telop data for each candidate song.

For example, it is assumed that the 10 keywords shown in FIG. 3 are transmitted from the user terminal M of the user U. Further, it is assumed that songs X1 to X10 are specified as candidate songs.

In this case, the detection unit 200 reads the lyrics telop data of each of the songs X1 to X10 from the storage means 20a. Then, the detection unit 200 confirms for each song whether or not the received 10 keywords are included in the lyrics. For example, when the detection unit 200 has a word that completely matches or partially matches a keyword in the lyrics, the detection unit 200 detects the keyword as a keyword related to the word in the lyrics. For the detection of the keyword, for example, the technique described in JP-A-2001-22361 can be used.

On the other hand, even if the keyword and the word in the lyrics do not match, the keyword and the word may be related (for example, the word "children" as opposed to the keyword "athletic meet"). Therefore, a database is constructed in advance by associating a plurality of related words with one keyword using machine learning. Then, the detection unit 200 may detect the keyword by using the database. Alternatively, an external server may be used to detect the relationship between the keyword and the word.

FIG. 6 is a diagram showing the relationship between the words in the lyrics of the music X1 and the 10 keywords included in the keyword information transmitted from the user terminal M. According to this example, six keywords related to the word in the lyrics of the song X1 are detected.

(Setting part)
The setting unit 300 sets a candidate song in which the number of detected keywords satisfies a predetermined condition as a recommended song, and associates the keyword identification information of the detected keyword and the word in the lyrics with the song identification information of the recommended song.

The predetermined condition is a condition for setting a recommended song, such as "the number of keywords is ● or more", and is set in advance.

Here, it is assumed that only the music X1 satisfies a predetermined condition with respect to the number of keywords of the music X1 to the music X10 detected by the detection unit 200. In this case, the setting unit 300 sets the music X1 as the recommended music.

The setting unit 300 associates the keyword IDs of the six keywords detected for the music X1 and the words in the lyrics corresponding to the keywords with the music ID of the music X1 (see FIG. 7).

(Image data receiver)
The image data receiving unit 400 transmits the keyword identification information associated with the music identification information of the set recommended song to the user terminal, and receives the image data specified based on the keyword identification information.

After the setting unit 300 sets the recommended song, the image data receiving unit 400 transmits the keyword ID associated with the song ID of the set recommended song to the user terminal M.

The second transmission processing unit 14c of the user terminal M identifies the image data corresponding to the keyword ID received from the karaoke device K from the image data stored in the storage means 10a. The second transmission processing unit 14c transmits the specified image data to the karaoke device K.

The timing of transmitting the image data specified by the second transmission processing unit 14c may be any time until the karaoke performance of the recommended song is started, such as when the recommended song is reserved.

For example, when the song X1 is set as the recommended song, the image data receiving unit 400 uses the keyword IDs "ID *** 0002", "ID *** 0003", "ID *** 0004", and "ID **". "* 0008", "ID *** 0009", and "ID *** 0010" are transmitted to the user terminal M.

The second transmission processing unit 14c refers to the table (see FIG. 3) stored in the storage means 10, and refers to the six image data “IMG002.jpg”, “IMG003.jpg”, which correspond to the received keyword IDs. Identify "IMG004.jpg", "IMG008.jpg", "IMG009.jpg", and "IMG010.jpg".

After that, it is assumed that the user U selects the music X1 via the user terminal M or the karaoke device K. In this case, the second transmission processing unit 14c reads the specified six image data from the storage means 10 and transmits the specified six image data together with the keyword ID to the karaoke device K.

The image data receiving unit 400 associates the received image data with a word in the lyrics based on the keyword ID (see FIG. 8).

In the present embodiment, the image data receiving unit 400 transmits the music identification information of the set recommended song to the user terminal together with the keyword identification information.

For example, when the music X1 is set as the recommended music, the image data receiving unit 400 transmits the music ID "ID *** X1" of the music X1 to the user terminal M. In this case, the notification unit 14d of the user terminal M can notify the user of the music X1 as a recommended music.

After that, it is assumed that the user U selects the music X1 via the input means 13. The reservation processing unit 14e transmits the music ID of the music X1 to the karaoke device K. At this time, the second transmission processing unit 14c reads out the specified six image data from the storage means 10 and transmits the specified six image data together with the keyword ID to the karaoke device K.

(Display control unit)
The display control unit 500 superimposes the lyrics telop based on the lyrics telop data on the background image and displays it on the display means in synchronization with the karaoke performance of the music.

For example, the karaoke device K reserves the music X1 by registering the music ID of the music X1 received from the user terminal M in the reservation queue.

After that, it is assumed that the user U instructs the karaoke performance of the music X1 via the user terminal M or the remote control device 60 of the karaoke device K. In this case, the karaoke device K reads the music data of the music X1 from the storage means 20a and starts the karaoke performance based on the accompaniment data. Further, the karaoke device K superimposes the lyrics telop based on the lyrics telop data on the background image based on the background image data and displays it on the display device 40 in synchronization with the karaoke performance.

Here, in the present embodiment, when the display control unit 500 includes a word in the lyrics related to the detected keyword in the lyrics telop to be displayed, the display control unit 500 selects the image data specified based on the keyword identification information of the keyword. Use to display the background image.

Specifically, when displaying the lyrics telop, the display control unit 500 confirms whether or not the word related to the detected keyword is included in the displayed lyrics telop.

For example, in the above example, when displaying one lyric telop T1 for the music X1, the words "friend", "Japan Sea", and "journey" related to the detected keyword among the words included in the lyric telop T1. , "Drive", "Children", "Wedding" are included.

Here, it is assumed that the word "friend" related to the detected keyword is included in the lyrics telop T1. In this case, the display control unit 500 reads out the image data "IMG0002.jpg" associated with the word "friend" and displays an image based on the image data "IMG0002.jpg" as a background image.

On the other hand, for example, it is assumed that none of the words related to the detected keyword is included in the lyrics telop T2 following the lyrics telop T1. In this case, when displaying the lyrics telop T2, the display control unit 500 displays a background image based on the background image data of the music X1 stored in the storage means 20a.

The display control unit 500 performs the same processing every time the lyrics telop is switched.

If the display control unit 500 does not include a word related to the detected keyword in a certain lyrics telop, the display control unit 500 may display the image based on the image data used in displaying the previous lyrics telop as it is. In the above example, when displaying the lyrics telop T2, the display control unit 500 may continue to display the image based on the image data “IMG0002.jpg” as the background image.

Alternatively, one lyric telop may contain multiple words. In this case, the display control unit 500 may display an image based on the image data associated with any one word, or may display a plurality of images based on the plurality of image data associated with the plurality of words. The images may be switched and displayed.

For example, when the song X1 is set as the recommended song, the karaoke device K causes the display device 40 or the remote control device 60 to display the song name and the singer name of the song X1.

It is assumed that the user selects the music X1 via the remote control device 60. In this case, the karaoke device K reserves the music X1 by registering the music ID of the music X1 in the reservation queue.

Further, the image data receiving unit 400 transmits the keyword ID associated with the music ID of the music X1 to the user terminal M, and receives the image data specified based on the keyword ID. Subsequent processing is the same as the processing in the embodiment.

By adopting such a configuration, the user terminal does not need to include the notification unit 14d and the reservation processing unit 14e.

The above embodiment is presented as an example and does not limit the scope of the invention. The above configurations can be implemented in appropriate combinations, and various omissions, replacements, and changes can be made without departing from the gist of the invention. The above-described embodiments and modifications thereof are included in the scope and gist of the invention, as well as in the scope of the invention described in the claims and the equivalent scope thereof.
