Synchronizing the internal time code
generator to an external time code
Make these settings to synchronize the internal time
code generators of multiple VTRs, or to record the
playback time code signal of an external VTR without
waveform attenuation.
1 To synchronize the internal time code generator
to external LTC
Connect the TIME CODE IN connector to an
external time code generator or the time code
output connector of an external VTR.
To synchronize the internal time code generator
to VITC of the input video signals
Select the input video signals by pressing the [F1]
(VIDEO IN) button in the PF1 menu.
2 Set the following function buttons as shown below:
[F6] (TCG SOURCE) button: To ext.
[F7] (TCG MODE) button: To regen (regenerate).
[F10] (VITC) button: To on when recording
VITC.
[F5] (TC SEL) button: To LTC when
synchronizing to LTC. Set to VITC when
synchronizing to VITC.
When the settings have been completed, the
internal time code generator starts operating in
synchronization with the external time code
generator.
The following table shows the conditions specified by
the various settings of the [F6] (TCG SOURCE) and
[F7] (TCG MODE) buttons.

Records the time

from a set value.
To check the running of the internal time code
generator
Press the STOP button to stop the VTR, then press the
REC button.
4-3-4 Selecting the Time Code
Running Mode (RUN MODE)
Press the [F8] (RUN MODE) button to select the time
code running mode.
free: The time code advances when the power is on
regardless of the VTR’s operation mode.
rec: The time code advances only during recording.
4-3-5 Selecting the Drop Frame
Mode (DF/NDF) (DVW-A500/1 and
500/1 only)
Press the [F9] (DF/NDF) button to select the running
mode for the CTL counter and the time code generator.
DF: Drop frame mode
1)
(DF is displayed.)
NDF: Non-drop frame mode
2)
(NDF is displayed.)
Note
When the [F7] (TCG MODE) button is set to regen,
the drop frame mode is inoperative since the time code
generator is synchronized to the playback time code.
1) Drop frame mode
In order to compensate for differences between time
code values from the time code generator and the actual
time, the drop frame mode causes the time code
generator to omit the first two frames (frame 00 and 01)
in each minute except the tenth.
2) Non-drop frame mode
A mode of advancing the time code in such a way that
the difference in frame values between real time and the
time code is neglected. Using this mode produces a
difference of approximately 86 seconds per day between
real time and the time code.
