Abstract:
A system synchronizes a video presentation to a master time reference (e.g., a corresponding audio presentation) by modifying a video cadence. The system detects when a displayed video leads or lags a master time reference by a programmable level or more. The system minimizes the synchronization error by inserting or removing source video frames to or from a frame cadence pattern.
