Abstract: Techniques for synchronizing audio and video content for presentation to a user at a same rate are provided. Streams of content from two or more sources of media, each media source having an associated clock, are synchronized by a synchronizing component and processor with respect to a master clock. As well, techniques are provided for ensuring that output devices are synchronized at preview startup. That is, such techniques ensure that the output devices start playing the media at the same time as well as at the same rate.
