qa DF/NDF (drop frame/non-drop frame) switch
This switch selects whether the time code advances in drop frame mode
or non-drop frame mode. This switch is effective only when the format is
set to one of 29.97 PsF, 30 PsF, 59.94 I or 60 I in the MULT FORMAT
page of the MAINTENANCE menu.
DF: Drop frame mode
1)
NDF: Non-drop frame mode

qs REAL TIME switch
This switch selects whether or not real time is to be recorded as VITC
user bit data. It is also used for setting the real time.
ON: Real time is recorded as VITC user bit data.
OFF: Real time is not recorded as VITC user bit data.
SET: Sets the real time.

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 format is set to either 29.97 PsF
or 59.94 I in the MULT FORMAT page of the MAINTENANCE menu, 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 format is set to either 29.97 PsF or 59.94 I in the MULT
FORMAT page of the MAINTENANCE menu, there will be a discrepancy
between the actual time and the time code value of about 86 seconds per one day
of recording. In case of 30 PsF and 60 I, a discrepancy will not occur.
