Synchronizing the Internal
Timecode Generator With an
External Signal — External Lock
You can synchronize the internal time code generator
to an external time code signal (TC) input to this unit.
Use this method to synchronize the time code
generators of a number of VCRs, or to carry out
recording maintaining the synchronization between the
source video and time code.
In this case, the settings of the sub LCD menu items F-
RUN/R-RUN and DF/NDF are ignored.
You can synchronize the internal time code generator
to one of the following external time codes.
• The time code (TC) output of an external time code
generator or external VCR connected to the TC IN
connector
• The time code (VITC) present in a video signal input
to the unit
• The time code (TC/VITC) input to the SDTI(QSDI)
INPUT connector (when fitted with the optional
DSBK-150) or i.LINK connector (when fitted with
the optional DSBK-140/160A) of the unit
To synchronize to an external time code
signal
Proceed as follows.

• When synchronizing to an external time code
Connect the time code output of the external time
code generator or external VCR to the TC IN
connector.

• When synchronizing to the time code (VITC) in
an input video signal
In the input selection section, select an input
video signal containing VITC, then select TC or
VITC with extended menu item 613.

Set switches on the control panel and the sub LCD
menu as follows.
TC SELECT switch:
TC or VITC according as
you are synchronizing to TC or VITC
TC INT/EXT switch:
EXT
Sub LCD menu item VITC:
• To record the time code (VITC) in the input
video signal as VITC, set to OFF.
• To record the time code generated by the
internal time code generator as VITC, set to
ON.
This starts the internal time code generator running in
synchronization with the external time code generator.
Once the internal time code generator is synchronized
with the external time code generator, even if the
external time code generator connection is removed,
the internal time code generator continues to run.
Note
When the input mode is SDTI or i.LINK (the SDTI or
i.LINK indicator is present in the subsidiary LCD),
then setting the TC INT/EXT switch to the EXT
position automatically synchronizes the internal
timecode generator to the timecode transferred through
the SDTI (DSBK-150) or i.LINK (DSBK-140/160A)
interface.
Note that when the TC INT/EXT switch is set to EXT,
the advance mode and frame count mode (DSR-70A
only) are automatically set as follows.
Advance mode:
free running
Frame count mode (DSR-70A only):
the same as
the external timecode signal (drop frame or non-
drop frame)
Checking the synchronization to the
external signal
Press the STOP button to stop this unit, then press the
REC/SEQ button.
Watch the time data display, and check that the values
displayed coincide with the external timecode values.
