Abstract
A karaoke system sounds a karaoke song designated according to a request command. The system includes a record unit defining a closed data source for readably recording a karaoke song, and a playback unit for reading the record unit to reproduce an audio signal representative of the karaoke song such that the record unit and the playback unit compose a playback karaoke equipment. The system further includes a supply unit defining an open data source for accessibly supplying a song data prescriptive of a karaoke song, and a synthetic unit for processing the supplied song data to synthetic size an audio signal representative of the karaoke song such that the supply unit and the synthetic unit compose a synthetic karaoke equipment. A total control unit is provided for selectively activating either of the playback and synthetic karaoke equipments according to a request command to achieve efficient use of the closed and open data sources. A sound unit receives the audio signal from the activated one of the playback and synthetic karaoke equipments to thereby readily sound a designated karaoke song.
