This paper presents a synchronization model for hypermedia presentations. Several media, continuous, like video and audio files, and non-continuous, like text pages and images, are delivered separately in a distributed environment like the World Wide Web, and presented to the user in a coordinated way. The model is based on a set of synchronization relationships which define media behavior during presentation playback, channels in which to play them, and the effects of user interaction. The model is suited for a wide range of applications, among which self and distance education, professional training, Web advertising, cultural heritage promotion and news-on-demand are good representatives. The model is formally described in terms of changes in the presentation state due to media-related events. A virtual exhibition is analyzed as a test bed to validate the model.
