Abstract

A method of synchronizing digitized audio information (113) and digitized picture information (105) establishes a reference time base (109) based on timecodes (107 & 117) included with the audio and picture information. The reference time base may be used to synchronize output between a digitized source and one which may be digitized or undigitized.
