A karaoke network system includes a central station for serving karaoke data and image data, and a group of karaoke terminals connected to the central station through a communication line having a common channel and a plurality of parallel channels for locally presenting a karaoke accompaniment and a background picture. The central station includes a first server responsive to a request command from karaoke terminal for transmitting to the common channel requested karaoke data individually addressed to the karaoke terminal, and a second server operative independently of the first server for transmitting to the parallel channels a plurality of different image data continuously broadcast to each karaoke terminal. The karaoke terminal includes an admitter for admitting the karaoke data addressed thereto from the common channel, and a selector for selecting one of the parallel channels to admit therefrom image data associated to the admitted karaoke data, such that the karaoke terminal can present the karaoke accompaniment and the background picture according to the simultaneously admitted karaoke data and the image data.
