Abstract
A karaoke network system is composed of a central station for providing a data, and a local terminal connected to the central station through a communication line; for presenting an event according to the provided data and being switchable between a working state and an idling state in response to a request. The central station responds to a call from the local terminal for providing a song data representative of a karaoke event to the local terminal through the communication line. The central station further down-loads a program data which sequentially prescribes spare events into the local terminal through the communication line. The local terminal operates in the working state where a request is present for presenting the karaoke event based on the provided song data, and otherwise operates in the idling state where a request is absent for sequentially presenting the spare events according to the down-loaded program data so as to fill a blank period of the idling state.
