Karaoke apparatus with concurrent start of audio and video upon request

摘要

In a karaoke apparatus, an audio device is responsive to a request of a music piece for starting karaoke performance of the music piece to accompany a live singing voice of the music piece. A monitor device displays a background image selected from a temporary picture having a short term and a permanent picture having a long term in matching with the music piece to support the karaoke performance. A first video device is enabled initially without a substantial delay time when the audio device starts the karaoke performance for providing the temporary picture corresponding to the requested music piece. A second video device is enabled subsequently to the first video device with a substantial delay time after the audio device starts the karaoke performance for providing the permanent picture corresponding to the requested music piece. A control device operates when the karaoke performance is started upon the request for initially feeding the temporary picture provided from the first video device to the monitor device until the second video device is enabled, and operates when the second video device is enabled for subsequently feeding the permanent picture provided from the second video device to the monitor device in place of the temporary picture so that the background image displayed on the monitor device is switched from the temporary picture to the permanent picture.
