Patent ID: 6930620

Claim:
A method comprising: providing a filter graph comprising multiple filters, the filter graph being configured to process multiple timestamped data streams for rendering the data streams in accordance with data stream timestamps; providing a synchronization module associated with the filter graph, the synchronization module being configured to: query individual filters of the filter graph to ascertain input timestamp-to-output timestamp mappings, compute adjustments that are to be made to output timestamps in order to synchronize the data streams, and instruct individual queried filters to adjust their output timestamps in accordance with computed adjustments; querying individual filters of the filter graph, using the synchronization module, to ascertain input timestamp-to-output timestamp mappings; computing, based on the ascertained input timestamp-to-output timestamp mappings, adjustments that are to be made to output timestamps in order to synchronize the data streams; and synchronizing the data streams by instructing one or more of the queried filters to adjust their output timestamps in accordance with the computed adjustments.
