Abstract
Abstract The invention disclosed herein is a digital audio workstation for the audio portions of video programs. It combines audio editing capability with the ability to immediately display video images associated with the audio program. The invention detects an operator's indication of a point or segment of audio information and uses it to retrieve and display the video images that correspond to the indicated audio programming. Another aspect of the invention is a labeling and notation system for recorded digitized audio or video information. The system provides a means of storing in association with a particular point of the audio or video information a digitized voice or textual message for later reference regarding that information.
