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. 100anormal speed).
The time code values are indicated using the display
and superimpose functions.

ttt tHours Minutes Seconds Frames
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.
3Set the run mode for the time code generator using
setup menu No. 513 (RUN MODE).
REC:
The internal time code generator is advanced
during recording.
FREE:
When the power is on, the internal time code
generator is advanced regardless of the
operation mode.
4Set the TCG switch to REGEN 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 TC PRESET button.
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 TC PRESET button to set the start number
of the time code or user’s bit.

as an optional accessory) in the VTR, the time code
value is also superimposed onto the video signals
which are output from the SDI OUT 3 connector.
OWhen the time code signal cannot be read, the time
code is automatically interpolated by the CTL
signal.
The display appears as shown below.

External synchronization of video
output signals
The video output signals are output in synchronization
with the REF VIDEO input signal or video input signal.
As shown in the figure below, this signal is selected in
accordance with the setup menu settings, VTR mode
and availability of the video input signal.
Synchronization is determined as follows depending
on the availability of the REF VIDEO input signal
when “BB”, “CB100” or “CB75” has been selected as
the setup menu No. 600 (INT SG) setting.

Audio V fade function
When editing tapes, the edit point splicing selection
(setup menu No. 311 and 312) information is recorded
on the tape. This information is then sensed during
playback, and V fade or cut processing is
automatically performed for these sections. 
However, only when the playback fade selection (No.
727) is AUTO.

OWhen the playback fade selection (No. 727) is
CUT, cut processing is performed for all splices.
OWhen the playback fade selection (No. 727) is
FADE, V fade processing is performed for all
splices.
