Abstract
A method and apparatus for simplifying the steps needed to produce a graphical cue to words being displayed as they are to be sung by a performer such as in Karaoke. The production of a CD-Graphics (CD-G) product containing compact disc ("CD") audio accompanied with a visual presentation of the lyrics is facilitated. In the end CD-G product, the lyrics are displayed on a CRT as white letters against a chroma keyed background (usually blue). An operator is able to precisely control the appearance of the lyrics of the display and the filling of the displayed lyrics in time with the music. The color of the fill can be specified e.g., to distinguish male solo or female solo or combination. The operator may also create display titles and other stylized graphical images for display during interludes where there is music and no lyrics. The operator may also specify the way in which graphical elements are put on the screen e.g., painted from left to right, right to left, spiral out from the center, etc.
