ABSTRACT:
In a network karaoke system, a center station transmits song data, and a plurality of karaoke terminals communicate with the center station to receive therefrom the song data so that each karaoke terminal can provide a karaoke service based on the received song data. The center station has a first transmitter that broadcasts the song data to transmit the same simultaneously to all of the karaoke terminals, and a second transmitter that responds to a request from each karaoke terminal to individually transmit the song data to each karaoke terminal. Each karaoke terminal has a first receiver that is capable of receiving the song data broadcasted by the center station, a detector that detects when the first receiver has failed to receive the broadcasted song data for communicating with the center station to notify thereto the request for re-transmission of the song data, and a second receiver that receives the song data re-transmitted from the second transmitter of the center station in response to the request.
