Abstract
A method for providing a full motion synched compatible audio/visual interactive television display from a plurality of syllable synched compatible audio choices for a common full motion video frame presentation. Two or more audio channels are synched to a common video channel by first recording the most likely branch and then rerecording the audio portions for the alternate branches by syllable synching the alternate branch choices to the original video presentation so as to make the video compatible with all audio channels. Animated characters, such as puppets, cartoon animations or humans, are used in the video with the audio being synched to the mouth movements of such an animated character so that all branches appear to be visually the same. The same techniques can be used to convert appropriate preexisting non-interactive programming into interactive programming.
