Methods and systems for synchronizing data streams
First Claim
1. A method comprising:
- providing at least one time-stamped data stream that is to be rendered in accordance with data stream timestamps; and
synchronizing said at least one time-stamped data stream relative to a reference by adjusting one or more timestamps of said at least one time-stamped data stream.

Abstract
Methods and systems are provided for synchronizing various time-stamped data streams. The data streams can be synchronized to another data stream or to a point of reference such as a reference clock. In one embodiment, synchronization processing takes place in association with a filter graph comprising multiple filters. The filter graph is configured to process multiple timestamped data streams for rendering the data streams in accordance with data stream timestamps. A synchronization module is provided and is associated with the filter graph queries individual filters of the filter graph to ascertain input timestamp-to-output timestamp mappings. The module computes adjustments that are to be made to output time stamps in order to synchronize the data streams, and then instructs queried filters to adjust their output timestamps in accordance with its adjustment computations.
