Abstract
A method is designed for feeding karaoke data representative of karaoke performance to a karaoke apparatus having an audio section and a video section. The method is conducted by the following steps. The initial step is formatting the karaoke data containing various kinds of data items including music control data and word control data into a plurality of packets such that each packet is formed of a body containing a segment of the karaoke data and a header containing identification information indicating the kind of the karaoke data contained in the body of each packet. The next step is delivering the plurality of the packets in a stream to the karaoke apparatus according to a predetermined order by which the karaoke apparatus time-sequentially processes the stream of the packets. The further step is selectively distributing the music control data contained in the processed packets to the audio section in accordance with the identification information to thereby enable the audio section to generate music tones of the karaoke performance. The last step is selectively distributing the word control data contained in the processed packets to the video section in accordance with the identification information to thereby enable the video section to display lyric words of the karaoke performance in synchronization with the music tones.
