Abstract
There is provided a method for automatically synchronizing playback between a first media service and a second media service, both services corresponding to the same media content source. Common audio events in the first media service and the second media service are matched. A playback timing of at least one of the first media service and the second media service is adjusted, based on a result of the matching step, so as to automatically synchronize the playback between the first media service and the second media service.
