Abstract
In the karaoke system 1, a center 3 is connected to a plurality of karaoke terminals 5 by a coaxial cable 7. The center 3 divides the karaoke song data stored in the memory device 13 over several channels and transmits all the karaoke song data within a fixed time period in succession to the karaoke terminals 5 via the coaxial cable 7. This operation is performed regardless of whether or not a song is requested from one of the karaoke terminals 5. Whether the karaoke data transmitted in succession is data of a requested song is determined by the control portion 41 of a karaoke terminal 5. If so, karaoke performance processes are performed wherein the karaoke data is reproduced and the orchestral accompaniment and lyric image is outputted.
