In other words, a specific video is displayed as a background video for a specific music, so that the interest of the karaoke user is increased. In addition, if a new singer, a singer trying to sell a new song, a group promotion image, or the like is used as the specific image, an advertising effect can be obtained.

On the other hand, when performing with karaoke data having no specific video data, the video data transmitted from the central unit can be appropriately selected from the genre-specific video data and displayed as a background video as in the conventional case. The amount is not huge. Further, since the background video storage unit 15a can store the specific video data received from the central device, it is not necessary to receive the specific video data once received, for example. For this reason, for example, the time spent for receiving the specific video data can be reduced, and the karaoke user is less likely to wait.

Although the present invention has been described with reference to the embodiments, the present invention is not limited to such embodiments, and it goes without saying that various embodiments can be made without departing from the spirit of the present invention. For example, if a period of one month, three months, or the like is set and specific video data after the period is deleted from the storage of the video data storage unit, excessive specific video data is stored in the video data storage unit. Can be avoided, and the storage capacity can be reduced. In addition, if videos suitable for a particular season or promotional videos that often end their roles in a short period of time are stored for a long period of time, the efficiency of the video data storage means may decrease. The drop can also be prevented.

Although a hard disk is exemplified as the karaoke data storage means and the background video storage means (specific video data storage means), a floppy disk, a semiconductor memory, a compact disk, a magneto-optical disk, a bubble memory, or the like may be appropriately selected. Can be used.

It is also possible to adopt a configuration in which, for example, data for a background image transmitted from a central device is displayed on a monitor display (display device) in real time without providing a background reproduction device including a background image storage means.
