[Problem to be Solved by the Invention]
By the way, if the user can make a medley music by combining his favorite music, he can enjoy many music at a time, so the user tries to select as many music as possible. If you enjoy karaoke with a small group of people, there will still be no problem. However, in the case of enjoying karaoke in large numbers, if each person sings a large number of medley songs, it takes time to perform one medley performance, and the order does not come easily. Then people other than the singer feel frustrated or bored.
[0005]
Also, even if the singer himself wants the song he wants, if he chooses too many songs, he will get tired of the performance for a long time, or if he is not confident that he can sing, it will be easy to sing You may want to finish it.
[0006]
Therefore, the present inventor considered that it would be convenient to be able to specify the length of performance of the medley music according to the situation. That way, not only is it useful for caring for other users, but it can be used separately when the user wants to enjoy a large number of songs or enjoys a small number of songs. It is very convenient.

[0022]
=== Configuration Example of Section Identification Information ===
As a characteristic feature of the present invention, the karaoke data for each karaoke piece stored in the karaoke database is provided with section identification information for designating a performance section (medley part) to be processed during the medley performance. ing. The section identification information is attached as header information of music performance data, and a plurality of medley parts are defined corresponding to the length of the medley performance in the form of a script for each music performance data.
[0023]
FIG. 6 shows a data configuration example of the section identification information. The music performance data describes performance processing to be executed in association with the elapsed time from the start of the performance. Therefore, delimiters (a to f in the figure) can be attached corresponding to the elapsed time from the start of performance. The script of the section to be played (section identification information) can be described by a delimiter indicating the start / end of the section.
[0024]
For example, in FIG. 6, three types of section identification information including “long-time medley part”, “standard medley part”, and “short-time medley part” are defined by the order of performance length. The script of each part is defined by a section start code of a, c, e and a section end code of b, d, f. That is, for the performance instruction of “part for long time medley”, the performance processing is performed in the sections a to b, the sections c to d, and the sections ef in order. Similarly, with respect to the performance instruction of “standard medley part”, the performance processing is sequentially performed in the sections a to b and the sections ef. In addition, in response to the performance instruction “part for short time medley”, only the sections ef are played.
The section identification information is accompanied by information on the standard performance time of each part. The music performance data can be obtained by being configured so that the performance required time (standard performance time) at the standard speed can be known by the synchronization signal.
[0025]
=== Medley editing function ===
A user who desires a medley performance designates a plurality of desired music pieces by various designation methods exemplified below, and transmits (inputs) a medley editing command together with information on the length of the medley performance to the karaoke performance apparatus.
[0026]
<First designation method>
If the user feels troublesome to select a specific request candidate song from the above notepad, or if it is difficult to narrow down to a specific song, reserve a medley performance consisting of the songs entered in the notepad. can do. The user touches the “memo pad” button 21 from the top screen (FIG. 4) to switch to the memo pad list screen in the same manner as in the case of the performance reservation using the memo pad described above, and further includes the contents. Touching the notepad displays a list of songs entered in the notepad. The outline of the screen at this time is shown in FIG. When the “medley performance” button 22 arranged on this screen is touched, a screen for designating the length of the performance is displayed by order information including three stages of “long”, “standard”, and “short”. When you select a button by touching one of these buttons, the medley editing command, the specified performance length information, and the song number of the song written in the notepad are listed in the order of the list. Sent to.
[0027]
The karaoke performance device that has received the information registers it as a medley musical piece in a performance reservation queue and performs medley editing. That is, the karaoke database is referred to for each music number in the designated order, and the performance of the medley part corresponding to the designated length is prepared. For example, if the user wishes to play “long” in the order of “music α, music β, music γ”, the long-time medley part of music α → the long-time medley part of music β → the length of music γ Preparation (editing) of the medley performance is performed with reference to the section identification information in the order of the time medley part.
Then, when the order of performance of the medley music is reached, the performance process of the medley part is executed in accordance with the edited permutation, and the medley performance is acoustically output.
[0028]
<Second designation method>
The karaoke performance apparatus according to the second designation method includes a user interface that can designate a desired time (length) of a medley performance as well as designation of a desired song. The user designates the desired song as in the first designation method and designates the target time for the medley performance. For example, three songs A, B, and C are designated as desired songs, the target time is set to “4 minutes”, and the medley editing command is transmitted to the karaoke performance apparatus.
[0029]
In the karaoke performance device, the standard performance time of the medley part is referred to for each musical piece, and the parts used are appropriately combined so that the total becomes 4 minutes (= 240 seconds) (or as close to 4 minutes as possible). To edit.
[0030]
For example, when the total performance time (A 90 seconds, B 80 seconds, C 85 seconds) of the long-time medley part of each music is 255 seconds, it is compared with the standard medley part or the short-time medley part of each music. Change the part to be used for any of the songs. On the other hand, when the total performance time (A 60 seconds, B 65 seconds, C 70 seconds) of the standard medley part is 215 seconds, the part used for any of the music is compared with the long time medley part of each music. change. In this case, A and C use the medley part for a long time, and if only B uses the standard medley part, it matches the target value of 240 seconds.
[0031]
Therefore, in the karaoke performance device, preparation (editing) of the medley performance is performed with reference to the section identification information in the order of the long-time medley part of the music A → the standard medley part of the music B → the long-time medley part of the music C. .
Then, when the order of performance of the medley music is reached, the performance process of the medley part is executed in accordance with the edited permutation, and the medley performance is acoustically output.
In addition, when the target value is not reached only by the designated medley target music, it is also possible to replay or select an appropriate music.
[0032]
<Third designation method>
When the desired music to be medley edited is designated, the karaoke performance apparatus according to the third designation method automatically determines the medley part to be used according to the number of music pieces and performs the medley editing. For example, when there are 10 or more desired songs, since the number of songs is large, all the songs are medley edited using a short medley part. If the desired song is in the range of 5 to 9 songs, medley editing is performed using the standard medley part of each song. In the case of less than 5 songs, the medley part is used for a long time because the number of songs is small. This method is convenient because it saves the user from having to specify the length of the performance.
[0033]
=== Other Embodiments ===
About the length of performance of a medley music, you may enable it to specify the information regarding length for every music. Then, for example, even if you want to make a medley performance for a short time as a whole, you can use a medley part for a long time only for your favorite music and use a short medley part for others. Is possible.
[0034]
It is also possible to select the music for medley editing on the spot. For example, it is also possible to provide a “medley edit” menu on the top screen (FIG. 4) of the multi-function karaoke remote control device, and to make a user interface that allows the user to select a song by clicking on it. Of course, it is needless to say that a user interface can be used for inputting on the operation panel of the karaoke performance apparatus main body without using the multi-function karaoke remote controller.
[0035]
Furthermore, the application of the medley editing method according to the present invention is not limited to a karaoke performance device. For example, the present invention can be applied to an incoming melody of a mobile phone or the like. By applying the method of the present invention to an incoming melody download site (server), it is possible to medley edit and download a plurality of melodies specified by the user. Alternatively, it is possible to medley edit a plurality of incoming melodies that are applied to a mobile phone or the like and saved by downloading or the like.
[0036]
【The invention's effect】
According to the technique of the present invention, medley editing with different lengths is possible depending on the situation. This makes it possible to freely change the performance time of the medley of a favorite song and let it be played by a karaoke performance device, etc., creating a new way to enjoy music and expecting an increase in the user base in the music-related industry it can.
