Preserving a record of timecodes used in editing a recorded digital video signal

摘要

A method of processing timecode data in a recorded digital video signal comprises assigning a first timecode to a first timecode location in the signal during recording, assigning the first timecode to a second timecode location and assigning a current second timecode to the first timecode location during a first editing step, and in subsequent editing steps sequentially changing the timecode locations of the timecodes so that the current timecode is assigned to the first timecode location and the previous timecodes are shifted sequentially through the other timecode locations.
