THE FIRST TIMING A SEQUENCE PROVIDES A PERMANENT TIME RECORD OF WHEN THE DATA IN HE STREAM FIRST ORIGINATED. THE SECOND TIMING SEQUENCE IS RE-WRITABLE WHEN THE DATA STREAM IS ALTERED, FOR EXAMPLE BY EDITING, SO AS TO ENSURE AN INTERNALLY CONSISTENT TIME TRACK IS PROVIDED EACH TIME THE DATA STREAM (30) IS CHANGED. THE TIMING SEQUENCES ARE DERIVED FROM ABSOLUTE REFERENCES SUCH AS GLOBAL POSITIONING SYSTEM (GPS) TIME. THE FIRST AND SECOND TIMING SEQUENCES MAY BE STORED SEPARATELY TO THE DATA STREAM (30). TWO OR MORE SETS OF SECOND TIMING SEQUENCES MAY BE PROVIDED, CORRESPONDING TO DIFFERENT PRESENTATIONS OF COMMON SETS OF DATA STREAMS (30).
