FIG. 3 is a diagram for explaining the management of the music data storage memory 36 by the reserved music management program 38b.

The reserved song management program 38b is shown in FIG.
As shown in (a), the process of creating a reserved song list, the process of deleting unnecessary songs, and the process of obtaining the next performance song are repeated in that order. This processing is performed in parallel with other processing (performance processing, etc.) as described above.

FIG. 3B shows an example of the reserved music list created as a result of the preparation of the reserved music list. 3 (c) and FIG.
(D) is a flow chart for explaining the processing of deleting unnecessary music and acquiring the next performance music, respectively.

The process of deleting unnecessary music will be described below with reference to the flowchart of FIG.

First, one music piece number of the music data stored in the music data storage memory 36 is acquired (S
1). If the song number can be obtained (S2; Y), check whether the obtained song number is included in the reserved song list,
If it is included (S3; Y), the process returns to S1 to obtain the next song number. If the acquired song number is not included in the reserved song list (S3; N), the music data corresponding to the song number is deleted from the music data storage memory 36, and the process returns to S1. If the song number cannot be obtained (S2; N), it means that no more music data is stored in the music data storage memory 36, and the process of deleting the unnecessary song is terminated.

The above processing will be specifically described in association with the reserved music list shown in FIG. At the time when the song with the song number "0100" in the playing column of FIG. 3B ends, the controller 32 refers to the reserved song list. Then, since the same song number “0100” is reserved at the position of reservation 3, the music data of the song with the song number “0100” is not deleted from the music data storage memory 36 but is retained as it is. Also, the song number "1234" in the column of reservation 1
When the performance of the song No. is finished, the song No. "1234" is not reserved after that, so the song No. "1234"
The music data of the song is deleted from the music data storage memory 36.

Next, with reference to the flowchart of FIG. 3D, the process of acquiring the next music piece will be described.

First, the control device 32 checks whether or not the next performance song is stored in the music data storage memory 36,
If not stored (S11; N), the free space of the music data storage memory 36 is checked (S12). If there is free space to store the music data of the next performance song (S13; Y), the music data of the next performance song is stored in the music data storage memory 36 (S15), and the process of acquiring the next performance song is performed. To finish. If there is not enough free space to store the music data of the next performance song in the music data storage memory 36 (S13; N), the music data storage memory 3
Delete the music data of the song with the lowest priority of 6 (S
14) and returns to S12. The process in S14 will be described later in detail with reference to FIG.

The above processing will be described in detail with reference to the reserved music list shown in FIG. While playing the song with the song number "0100" in the playing column of the reserved song list,
Next, the music data of the reserved music number "1234" is acquired. In the case where the music data of the music number "1234" is stored in the music data storage memory 36 and the processing for acquiring the next music performance is performed again (the performance processing and the reserved music management processing are performed in parallel). Therefore, the loop of the reserved song management process is repeated many times during the performance of the song), and the music data of the song with the song number “1234” has already been acquired, so the flowchart shown in FIG. Of S
When the result is 11, the result is Y, and the process of acquiring the next music piece is ended without doing anything. Further, when the song number “2214” of the reserved number 2 in the reserved song list of FIG. 3B is being played, the newly reserved song number “0100” cannot be acquired. Absent. This is because the music data of the song with the song number “0100” remains undeleted even after the performance of the song ends.

Next, the processing in S14 of the flow chart shown in FIG. 3D will be described. As described above, the music data storage memory 36 has a capacity capable of storing music data for several songs. After the performance, the music data of the song that is not reserved again is stored in the music data storage memory 3
6 is deleted (see FIG. 3C), the normal music data storage memory 36 has a margin.

However, if the music pieces are reserved in the order shown in FIG. 4A, the music data storage memory 36 has no free space for storing the next music piece to be played. In other words, in Fig. 4 (a), it is assumed that the songs with the song numbers "0011" to "0055" played five to one before are already reserved for each song. For example, when the song number “0066” is currently being played, the memory data storage memory 36 has a capacity enough to store the music data of the next reserved song number “0077”.
(See FIG. 4B).

In this case, the music data of a song having a low priority is deleted before the next performance song is stored. "Low priority" means that the reservation order in the reserved music list is later. In other words, look at the reserved song list in reverse order,
The music data stored in the music data storage memory 36 will be deleted. In FIG. 4A, the song number "0"
Music data of the songs "088" and "0099" are shown in FIG.
As shown in FIG. 5, since it is not in the music data storage memory 36, the song number “005
The music data of the song "5" is deleted from the music data storage memory 36.

The content of the music data storage memory 36 after the music data of the next performance music, that is, the music of the music number "0077" is stored is as shown in FIG. 4 (c). In addition,
If you can't store the next song by deleting one song,
Similarly, the songs with the highest reservation order are deleted in order. That is, the processes of S12 to S14 in the flowchart of FIG. 3D are repeated.

The reserved music management process as described above is performed in parallel with other processes (performance process, etc.) operating in the karaoke terminal. Therefore, during the performance of a certain song, the next song to be played is prepared, so that the no-play time between songs is shortened. In addition, if the same song is repeatedly reserved, the music data transmitted to the karaoke terminal can be saved and played repeatedly.
It is possible to prevent the communication load from increasing.

In this embodiment, the karaoke terminal 22
The system including the centralized management device 10 that manages a plurality of karaoke terminals 22 has been described, but a large number of recording media such as laser disks are housed inside the main body of one karaoke device, and recording is performed on the laser disks. The same method can be applied to a system in which the stored music data is temporarily stored in the music data storage memory 36 and then played.

[0039]

As is apparent from the above description, according to the music reproducing apparatus of the present invention, the deletion and holding of the music data of which the performance has ended are managed according to the reservation status. It is possible to reduce the load of preparing a song.
