6 to 8 are flowcharts showing the operation of the karaoke apparatus. ◇
FIG. 6 is a flowchart showing an operation when a music selection command is input. When a music selection command is input from the re-common 30 or the like (n1), music data corresponding to the music code included in the music selection command is retrieved from the HDD 17 (n2), and performance time data is read from the header (n3). This performance time is added to the tail of the reservation table together with the music code (n4), the reserved display is displayed on the monitor (n5), and the operation is finished. The reserved display is composed of a song name and a waiting time until the performance of the song starts. The waiting time is calculated by the total performance time of the already reserved music + the remaining time of the currently played music + the switching time of the music × the number of reserved music.
[0023]
FIG. 7 is a flowchart showing the operation at the start of karaoke. The music data of the first music in the reservation table is searched (n10), the header is read (n11), and background video selection data is created (n12). The background video selection data is sent to the LD changer 30 (n13). The performance flag is set (n14), the music is deleted from the reservation table, the data for the second music and thereafter are shifted, and the data of this music is written into the performance data register (n15). After that, the sequence operation is started (n16).
[0024]
FIG. 8 is a flowchart showing an operation when a reservation list display command is input. When a reservation list display command is input (n20), it is determined whether or not a karaoke song is currently being played (n21). If the performance is being performed, the selector switch 36 is switched to the second video signal side, and the process proceeds to (n22) n23. If not playing, the process proceeds to n23 while keeping the first video signal side. At n23, data is read from the reservation table, and the waiting time is calculated for each song (n24). Based on this waiting time, a table as shown in FIG. 5 is created (n25), converted into pattern data for writing in the service information memory 32 (n26), and sent to the service information memory 32. As a result, the reservation list is displayed on the audience monitor 25, and if the karaoke song is not being played, the reservation list is also displayed on the singer monitor 26. After displaying for a certain time, the CPU 10 deletes the service information memory 32 and switches the switch to the first video signal side. As a result, the reservation list is displayed only on the audience monitor 25 during the karaoke performance, and the reservation list is displayed on all monitors when the performance is not being performed.
[0025]
When the karaoke performance is started while the reservation list is displayed, the changeover switch 36 is switched to the second video signal side at that time to delete the reservation list from the singer's monitor 26. . In the above embodiment, the selector switch 36 is switched to the second video signal side only when a reservation list display command is input even during karaoke performance. You may make it fix to the 2nd video signal side.
[0026]
In this embodiment, the reservation list is displayed as service information, but the service information is not limited to this. In the present embodiment, a changeover switch may also be provided on the audience monitor 25 side so that some images such as lyrics are not displayed on the audience monitor 25.
[0027]
If the karaoke device has a tempo switching function for songs, the waiting time for reserved songs may be recalculated every time tempo switching is performed.
[0028]
