Abstract
In a karaoke system, a central terminal and a plurality of karaoke terminals are connected by a coaxial cable. A polling modem modulates a polling signal to a predetermined channel signal and transmits it to a karaoke terminal and also receives a response signal (signal for responding as to whether a song has been requested) transmitted from the karaoke terminal in response to the polling signal. When a song is requested, the data transmission control portion retrieves the karaoke song data of the requested song from the memory, modulates it via the data transmission modem into an alternating current signal that differs from the channel of the polling signal, and transmits it to the karaoke terminal.
