Abstract
A system and method for synchronized playback and control of a movie (also referred to as time-based digital media). The movie includes one or more data structures, called "tracks", containing time-based data that is intended to be played together in a synchronized manner at a given rate of speed. The system and method allows two or more participants that are operating on different playback systems at different locations to simultaneously view and control the playing of the movie. The image on each participants display is kept synchronized with the others, providing a virtual co-location.
