Time Code & User’s Bit
Time code
The time code signal is generated by the time code
generator and recorded on the tape, and its value is
read by the time code reader. The time code is used
to display the absolute position of the tape in hour,
minute, second and frame increments.
The time code is written in the sub-code area (data
area) on the helical track. For this reason, the VTR’s
playback speed can be read out from the stop mode
to the slow-motion playback to high-speed playback.
The time code value is shown on the display and
superimposed on the screen.

User’s bit
The user’s bit refers to the 32-bit (8-digit) information
frame which is the only part of the time code signals
open to the user for use. It can be used to record the
operator number or other such information.
The alphanumerics which can be used for the user’s
bit are the numbers 0 through 9 and the upper-case
letters A through F.
