Abstract
A personal computer based, multimedia, data processing system includes a software solution to the problem of synchronizing two or more data streams which output data to two or more multimedia output devices. One stream is a master and each other stream is a slave. The master stream generates sync pulses that can be handled in two different synchronization methods, master-slave independent synchronization or master-driven slave synchronization. Sync pulses are generated with a predetermined granularity, and synchronization is achieved when a slave stream is out of tolerance. Adaptive resynchronization may be used to speed up or slow down a slave stream.
