Reference media data and monitored media data are accessed. Media data may be accessed as streams of media data, as media data stored in a memory, or any combination thereof. A first pattern of first media content (e.g., a video event) and a second pattern of second media content (e.g., an audio event) are identified in the reference media data, and their corresponding counterparts are identified in the monitored media data as a third pattern of first media content (e.g., a video event) and a fourth pattern of second media content (e.g., an audio event). After these patterns are identified, a first time interval is determined between two of the patterns, and a second time interval is determined between two of the patterns. A difference between the two time intervals is then determined and stored in a memory. This difference may be presented as a media synchronization error.
