Time code/user bit
Time code
The time code is used when the time code signal
generated by the time code generator (time code
signal generator) is to be recorded on the tape, its
values are to be read by the time code reader (time
code signal reader), and the absolute position of the
tape is to be displayed in increments of hours,
minutes, seconds and frames.
The time code is written in the sub-code area (data
area) of the helical track. This enables insert editing to
be conducted independently using the time code
alone. In addition, the VTR’s playback speed can be
read from the stop mode to slow-motion playback up to
high-speed play (approx. 50anormal speed/approx.
100awhen using DVCPRO tape).
The time code value appears on the counter display. It
is also superimposed onto the display of the TV
monitor which has been connected to the VIDEO OUT
3 connector or SDI OUT 3 connector, but it does not
appear on the front panel’s LCD monitor.

User bit
“User bit” refers to the 32-bit (8-digit) data frame
among the time code signals which has been released
to users. It enables operator numbers values to be
recorded.
The alphanumeric characters which can be used for
the user bit are the figures 0 to 9 and the letters A to F.
Setting the internal time code
1Set the VTR to stop mode.
3Use the TC (REC RUN/FREE RUN) switch to set
the operation mode in which the internal time code
generator is to be advanced.
REC RUN:
The internal time code generator is advanced
during recording.
The time code advances all the time when the
TC (REGEN/PRESET) switch is at the REGEN
position.
FREE RUN:
When the power is on, the internal time code
generator is advanced regardless of the
operation mode.
4Use the TC (REGEN/PRESET) switch to set the re-
generating mode.
REGEN:
In this mode, the continuity of the original time
code prior to editing is maintained.
OA more detailed setting can be performed
using setup menu No. 503 (TCG REGEN) and
No. 504 (REGEN MODE).
PRESET:
In this mode, recording is commenced from the
value which was set by the
(SHIFT+PLAYER).
ODuring automatic editing, whatever has been
selected for the menu No. 504 setting is used
for regeneration even when the TCG switch
has been set to PRESET.

5Use the (SHIFT+PLAYER) to set the
start number of the time code or user bit.
1Press the (SHIFT+PLAYER). The
left-most set of digits starts flashing.
2To change the value, turn the search dial while
holding down the search button.
3Turn the search dial to select the set of digits that
is to be set. The digits selected start flashing.
The setting ranges are as follows:
OTime code:
[625i system]
00:00:00:00 to 23:59:59:24
[525i system]
00:00:00:00 to 23:59:59:29
OUser bit:
00:00:00:00 to FF FF FF FF
4Repeat steps 2and 3to change any other
values.
5Once the start number has been set, press the
SET button.
In the FREE RUN mode, the time code begins to
