The CPU 14 stores the search data 18a, lyrics data 18b, performance data 18c, video data 18d, and pattern data 18e indicating various patterns of the video data 18d for each song.
8 are connected.

Further, a sound source 24 for reproducing the performance data 18c read from the hard disk 18 is connected to the CPU 14. A mixing amplifier 26 and a speaker 28 are connected to the sound source 24.
The data from the sound source 24 is amplified by a mixing amplifier 26 and output from a speaker 28.

An image control circuit 22 connected to the CPU 14
Is for displaying a lyric image based on the lyric data 18b of the hard disk 18 and displaying an image of a background video based on the video data 18d. The video is displayed on the CRT 30 connected to the video control circuit 22.

The search data 18a includes a music number and a file name corresponding to the music as shown in FIG.

As shown in FIG. 2, the performance data 18c
The PU 14 manages time, and is composed of music reproduction data, a lyrics timing flag indicating timing for displaying lyrics, and a background timing flag indicating timing for displaying background images. There are as many background image timing flags as the maximum number of background images that can be displayed during performance of a song, and all of them are given priority.

As shown in FIG. 4, the pattern data 18e includes a music number, a pattern number corresponding to the music number, the number of background images used in each pattern, and a background image number.

FIG. 2 shows the relationship between the flow of time during performance and data, and the operation of this embodiment will be described with reference to FIG.

First, the performance and display of the music are executed by the CPU 14.
The operation of will be described. When the song number is designated by the input key 10, the CPU 14 reads out the search data 18a from the hard disk 18, and reads the file name of the performance data 18c and the file of the lyrics data 18b of the song number of the search data 18a that matches the input song number. Get a name. CPU14
Is the performance data 18c and the lyrics data 1 from the file name.
8b is read from the hard disk 18. The pattern data is read out from the hard disk 18 based on the pattern number and the song number designated by the pattern designation key 12, and
Thereby, the video data number and the number of video switching are obtained. Then, the CPU 14 reads necessary video data 18 d from the hard disk 18.

Next, the CPU 14 starts playing, and if the performance data 18c is reproduction data for producing a sound, the sound source 24
The sound source 24 performs reproduction, and if the data is flag data, the lyrics data 18b and the video data 18d are transmitted to the video control circuit 2.
2 and the video control circuit 22 performs display.

Next, the characteristic operation of the present invention will be described.

The display timing flag of the selected song is 20
A case where there are five pieces and the number of pieces of video data 18d specified by the pattern data 18e is five will be described.

First, the CPU 14 sends reproduction data from the beginning of the performance data 18c to the sound source 24, and the number of display timing flags included in the start portion of the performance data is 1 and is 5 or less of the number specified by the pattern data. Therefore, the first video data 18d is transferred to the video control circuit 22.
To send to. Subsequently, the CPU 14 transmits the reproduced data to the sound source 24.
, The display timing flag is recognized. Since the number of this flag is 11, which is larger than the designated number of 5, the CPU 14 ignores this flag and does not perform the processing.
In this way, while the music is being reproduced, only the flag having the designated number of 5 or less is selected from the 20 flags, and the video data 18d is sent to the video control circuit 22 when the flag is set. If the number of flags is larger than 5, the processing is not performed. In this way, five images are displayed during the performance.

Next, a case where the number of video data 18d specified by the pattern data 18e in the same music piece is 10 will be described. In this case as well, the CPU 14 starts to transmit the reproduction data to the sound source 24, and upon recognizing the display timing flag, determines whether or not the value of the flag is greater than 10. If the display timing flag is 10 or less, the video data is sent to the display control circuit 22, and if the flag is larger than 10, it is ignored, so that 10 video data are displayed evenly during the performance.

That is, when the CPU 14 recognizes the background image timing flag among the flag data contained in the performance data 18c, the CPU 14 compares the number of video data indicated in the pattern data 18e with the priority of the flag, and If the priority shown by is larger than the number of sheets, video display is not performed, and if the priority of the flag is lower, video display is performed. In this way, the number of video data prepared in the pattern is set as the priority of the background image timing flag, and the display is switched evenly.

As described above, according to the present embodiment, for the video data of the background image of various patterns displayed in each music piece, the display switching timing is determined according to the number of background images used in the pattern of the background image data. By making the adjustment, the number of sheets for creating the background image data is not limited, and the viewer can enjoy the background image data more.

The present invention is not limited to the embodiments described above, and various changes can be made without departing from the gist of the present invention.

For example, the number of video data 18d that can be specified by the pattern data 18e is not limited to 5 or 10, but may be any number. Although the performance data includes flag data, the display timing flag may be handled as data different from the performance flag.
