ABSTRACT:
A synchronization system includes a motion event synchronizer and multiple application encapsulators which operate together to synchronize motion events operating in replicated multi-dimensional non-modified 3-D existing applications. The application encapsulators compress one or more user generated motion events together and then send the compressed motion events to the motion event synchronizer. The motion event synchronizer multi-casts the motion event to each of the application encapsulators in the synchronization system. The application encapsulators and the motion event synchronizer conduct a two-phase lock-step acknowledge and download enable protocol that ensures each application is downloaded with the same motion event at the same time. To ensure simultaneous motion event viewing at each user site, the application encapsulators interleave spacer events between adjacent motion events.
