Abstract:
1. A media processing system comprising control circuitry configured to: execute a first process for processing media, wherein the first process accesses a first timing source and a second timing source, and wherein the first process processes media based at least in part on first timing information derived from the first timing source; execute a second process for processing the media, wherein the second process accesses the second timing source but cannot access the first timing source, and wherein the second process processes media based at least in part on shadow timing information; wherein the first process sends 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 process with the first process; and wherein the shadow timing information is an estimate of the first timing information maintained by the second process.
