Time code and user’s 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 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’s bit
The “user’s 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 and other
values to be recorded.
The alphanumerics which can be used for the user’s
bit are number 0 to 9 and letters A to F.
