In the case of a song number designating ICM data, it is registered at the top of the reservation list, and this is executed next to the karaoke song currently being played (s3). On the other hand, if it is a normal karaoke song number, it is registered at the bottom of the reservation list (s4). If a karaoke song is not currently being played, the ICM data or karaoke song to which this song number is input is immediately executed.
[0030]
FIG. 7 is a flowchart showing the reservation execution operation. This operation is performed when the performance of the previous karaoke song is completed. First, it is determined whether or not there is a song number registered in the reservation list (s10). If there is no registered song number, an inter-song CM screening operation is executed. This inter-commercial CM is executed by ICM data, and displays the request best 20 and event information. If the song number is registered in the reservation list, the highest one is read (s11), and it is determined whether this is the song number designating the ICM data (s12). If it is the music number designating the ICM data, it is determined whether this is the music number designating the recording mode ICM data (s13). If the song number designates the recording mode ICM data, the recording mode operation of FIG. 8 is executed (s14). If the song number designates another ICM data, the process proceeds to the corresponding process. If the read music number is a music number designating normal music data, the music data of the music is read and a normal karaoke performance processing operation is executed (s15).
[0031]
FIG. 8 is a flowchart showing the recording mode processing operation. This operation is executed when the music number of the recording mode ICM data is read from the reservation list. First, the recording mode ICM data is read into the RAM 22 (s20), and the following operation is executed based on the script data and image data included in the recording mode ICM data (s21). First, the guidance screen shown in FIG. 9A is displayed. This guidance screen displays that this service is a billing service. If the user makes an OK corresponding to this (s22), the process proceeds to a charging process operation (s23). The billing processing operation (s23) is processing for communicating with the billing apparatus 10 to confirm that a predetermined amount of coins has been inserted, and subtracting this amount from the number of credits. When this billing process is completed (s24), the music selection for this recording mode is accepted (s2 5 ). If there is no OK input for the charging service (s22), and if the charging is not completed normally (s24), the recording mode operation is terminated as it is.
[0032]
When a karaoke song for the recording mode is selected (s25), the selected song data is read from the hard disk storage device 27 to the RAM 22 (s26), and the title of the karaoke song is shown on the singer photographed by the camera 6. Are combined to display a start screen and temporarily stop the operation (s27: see FIG. 9B). The singer looks at the start screen, checks his / her standing position, posture, clothes, etc. and then turns on the start key 53 to start the performance (s28). This start instruction uses the start key 53 of the commander 15, but a foot switch may be provided on the floor of the stage so that the singer can operate with his / her foot. Even if the commander 15 is not operated, the performance of the karaoke music automatically starts after a predetermined time (about 5 seconds) has passed (s29). In s30, the recording operation of the video CD recorder 9 is started, and at the same time, the performance operation of karaoke music is started (s31). The performance operation of the karaoke song is an operation of reading the event data of each track of the song data in synchronization with the tempo clock (s32) and outputting this data to each processing unit such as the tone generator 29 and the character pattern development unit 36. Then, it is confirmed that the music control data includes the camera control track (s34), and the control data (camera control data) read from the track is output to the drive control unit 66 of the video camera 6 (s35). . Thus, the direction and zooming of the video camera 6 are controlled in accordance with the singing of the singer while dancing with a predetermined choreography. The operation from s32 to s35 is continued until the music ends (s36), and when the music ends, the recording operation of the video CD recorder 9 is stopped (s37). Then, the monitor 7 or 8 accepts the selection of whether or not to reproduce the video that has just been recorded (s38). If there is an input for reproduction, the recorded video is reproduced and the monitor 7 or 8 is displayed via the display control unit 38. (S39). After the reproduction, this video CD is ejected (s40), and the recording mode operation is terminated. If it is selected not to reproduce in s38, the process proceeds to s40, the recorded video CD is ejected, and this operation is terminated. If the cancel key 55 is turned on during the reproduction of the video, the reproduction is stopped and the process proceeds to s40.
