Abstract
A karaoke apparatus sounds a karaoke accompaniment and displays visual information to perform karaoke play. An audio generator responds to a request for generating an audio signal. A sound component is switchable from an inactive state to an active state for receiving the audio signal to sound a karaoke accompaniment corresponding to the request. A video generator having a plurality of channels generates a plurality of video signals which represent visual information containing various items assigned differently to the representative channels. A channel selector switches the channels to select an adequate video signal so as to control the visual information. A monitor receives the selected video signal for displaying the visual information such that the displayed visual information includes a necessary item and excludes an unnecessary item for the karaoke play at least under the active state of the sound component.
