Abstract
A method of recording time code in a database is disclosed which makes it easy to search for video segments on a target medium while making the original source time code available on playback. As a video segment from a source medium is recorded on the target medium the time code from the first frame of the video segment is extracted and held. The number of frames of the video segment are counted to determine a duration, and at the conclusion of the video segment the extracted time code together with the duration and a location code indicating where on the target medium the video segment is stored are formed into a data structure that is stored in a break table in the database as a 'break' entry. The break table is sorted, optimized to eliminate any break entry overlaps, and updated after each new break entry.
