Abstract
In a method and apparatus for generating musical accompaniment signals corresponding to a musical program, there is provided a recording medium which has an audio storage unit and a lyric storage unit separate from the audio storage unit. The audio storage unit and the lyric storage unit respectively have a plurality of audio music data and a plurality of lyric data corresponding to a plurality of the musical programs stored therein. The lyric data include encoded text data and timing information. In operation, the audio music data and the lyric data corresponding to a selected one of the musical programs are retrieved from the recording medium. The encoded text data and timing information retrieved from the recording medium are decoded to obtain decoded data, and bitmap data are then generated from the decoded data. The bitmap data are synchronized with the audio music data retrieved from the recording medium in accordance with the timing information. The audio music data retrieved from the recording medium are provided to a sound card to obtain an audio output. The bitmap data are provided to a VGA card to obtain a video signal.
