Abstract
Synchronizing a data stream with an associated metadata stream by receiving a data stream and a metadata stream having a plurality of metadata events associated with the data stream, identifying within the data stream a plurality of data events, matching each of the data events to one of the metadata events in accordance with a matching criterion, and synchronizing the data stream with the metadata stream by effecting a relative time shift between the metadata stream and the data stream in accordance with a time shift adjustment value that results in the smallest sum of absolute differences between time indices of each matched data event and metadata event.
