Time code and user bits
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
the slow motion playback up to high-speed playback
(approx. 50
k
normal speed or approx. 100
k
normal speed
when using a DVCPRO tape).
The time code values are indicated on the display and
superimposed display.
User bits
The “user bits” refers to the 32-bit (8-digit) data frame among
the time code signals which has been released to users. It
enables operator numbers and other values to be recorded.
The alphanumerics which can be used for the user bits are
number 0 to 9 and letters A to F.
Setting the internal time code
1
Set the VTR to the stop mode.
2
Set
TC/CTL on the <HOME> menu to TC.
3
Set
SOURCE on the <TC> menu to INT (for
selecting the internal time code).
4
Setting
RUN MD on the <TC> menu
REC:
The time code advances simultaneously with the
recording.
FREE:
The time code advances, like time, irrespective of the
VTR operation.
5
Setting
TCG MD on the <TC> menu
REGEN
:
The continuity of the underlying time code in place
prior to editing is maintained.
PRE
:
The time code can be preset using the operation
panel controls or remote controller.
AUTO
:
The time code is automatically switched to REGEN or
PRE depending on the VTR’s operation mode: during
editing, REGEN is selected; at all other times, PRE is
selected.
