| Abstract: | This paper describes an event-based synchronization mechanism, which is at the core of the inter-media synchronization in
the upcoming standard for multimedia presentation, PREMO. The synchronization mechanism of PREMO is a powerful tool, based
on a small number of concepts, and on cooperation among active objects, and represents a synthesis of various synchronization
models described in the literature. This model can serve as a basis for the implementation of complex synchronization patterns
in multimedia presentations, both purely event-based, as well as time-based. |
