1) Drop frame mode
To eliminate the discrepancy between the actual time and the time code value
generated by the time code generator when the field frequency is 59.94 Hz, drop
frame mode drops two frames (frames 00 and 01) from the time code value at
the beginning of each minute except every tenth minute.
2) Non-drop frame mode
Non-drop frame mode does not perform the processing of drop frame mode. As
a result, when the field frequency is 59.94 Hz, there will be a discrepancy
between the actual time and the time code value of about 86 seconds per one day
of recording.
