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. The VTR’s playback speed can be
read from the stop mode to slow-motion playback up to
high-speed play (approx. 50 a normal speed approx. 100
a when using DVCPRO tape).
The time code values are indicated using the display and
superimpose functions.

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.
