Abstract

A karaoke apparatus is responsive to a request of a music piece for producing karaoke accompaniment to accompany a live singing voice of the music piece while reproducing a background video associated with the music piece. In the karaoke apparatus, a sound source device produces the karaoke accompaniment of the music piece in response to the request. A storage device stores video data representative of a piece of the background video which is associated with the music piece. The piece of the background video has a time length normally longer than a time length of the music piece. A central processing unit variably designates a read start point from which the piece of the background video should be reproduced. A drive device is responsive to the request for accessing the storage device to reproduce the background video from the read start point.
