Synchronizing the internal timecode
generator to an external timecode —
External synchronization
External Regen mode
You can synchronize the internal timecode generator of
this unit to an external timecode which is either of the
following.
• LTC signal connected to the TC IN connector
• VITC signal inserted in the video signal
• Timecode signal embedded in the SD-SDI signal: LTC
conforming to RP188
• Timecode signal embedded in the HD-SDI signal: LTC
or VITC conforming to ARIB STD-B4.2.0 and RP188
Use this capability when synchronizing the timecode
generators of multiple recorders, when recording the
playback timecode of an external VCR, or when you want
to record without breaking the relation of a source
timecode and a source image.
When an external timecode is input, the internal timecode
generator advance mode and frame count mode are
automatically set as follows.
Advance mode:
FREE RUN
Frame count mode:
same as the external timecode (drop-
frame or non-drop-frame )
Proceed as follows.

Depending on the type of external timecode, set the
signal input source and TIME CODE menu item
as follows.
1) Select the video signal input with the INPUT SELECT buttons
in the video/audio input selection section.
2) SD-SDI embedded TC only supports LTC. If SDI input is selected,
the synchronization priority sequence of external timecode is as
follows.
1
SD-SDI signal: RP188. HD-SDI signal: ARIB STD-B4.2.0, and
RP188.

An input to the TC IN connector
3) HD-SDI input supports VITC as embedded timecode, and SD-SDI
input supports VITC multiplexed into video signals.
When the timecode generator is in the regenerate mode
(when the setting of the TC MODE menu item is INT
REGEN or EXT REGEN), you can select whether to
regenerate both timecode and user bit data, or to regenerate
either one of them, in the TIME CODE >TCG REGEN
menu item
.
• When the input mode is i.LINK (the i.LINK indication
appears in the video area of the input signal display), if
you set the TC MODE menu item to EXT REGEN, then
the internal timecode generator is synchronized to the
i.LINK input and not to the TC IN input.
• Recording of VITC is supported only when the
recording format of this unit is DVCAM.
• When the TC MODE menu item is set to EXT REGEN,
and timecode is also input from an external device
connected to the HDV/DV connector, if the input
timecode includes discontinuities, or advances
incorrectly, the input timecode and the timecode to be
recorded on the tape may be out of step with the
timecode display on this unit. Also, when using a
recorded tape with timecode discontinuous in this way,
editing and search operations may not perform correctly
depending on the combination of equipment.
To check that an external synchronization
is present
Press the STOP button to put this unit in stop mode, then
press the REC button.
Watch the time counter display, and check that the value
agrees with the external timecode value.
