Abstract
Systems, methods, devices that enable the efficient synchronization of timing information from first time-based process to a second time-based process using periodic or event-driven synchronization messages are provided. In one aspect, the invention includes a media processing system having a first process for processing media based, at least in part, on first timing information derived from a first timing source and a second timing source. The system may also include a second process for processing the media based, at least in part, on second timing information derived from the first timing source. The first process may send one or more timing synchronization messages, generated based at least in part on the first timing source and the second timing source, to the second process to synchronize the second timing information with the first timing information.
