Abstract
A karaoke network system includes a host computer and a plurality of karaoke stations connected to the host computer via a communication line. When a new karaoke station is added to the karaoke network system or when a system program to be used by each of the karaoke stations is upgraded, a new system program is distributed from the host computer to the specified karaoke stations, Each of the karaoke stations has a first storage device for storing the new system program received from the host computer, and a second storage device that stores a system program currently executed to operate each of the karaoke stations. After rebooting each of the karaoke stations and thereafter, each of the karaoke stations is operated with the newest system program.
