Start Time

A value that is set in synchronizers, sequencers, or other equipment that is to be synchronized with some form of time code. The start time tells the device where to start its function in relation to the incoming time code. For example, on a sequencer that is being synchronized to a video tape the start time would be the time code value (usually SMPTE time code) where you want to sequence to begin playing. This is normally a few seconds before the beginning of the program material on the video. When that value of time code arrives the sequencer starts its playback (or recording as the case may be). The sequencer will usually continue to monitor the time code and adjust its speed so it stays in sync as the tape plays. Typically time code is striped to a whole tape from beginning to end so as to provide the maximum flexibility with start times and synchronization equipment later.
