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

2 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 mode1)

NDF: Non-drop frame mode2)

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.

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.
