Time Codes/User’s Bit
Time codes
Time codes are used to indicate the absolute position
of the tape in hour, minute, second and frame
increments: the time code signals generated by the
time code generator (time code signal generator) are
recorded on the tape and read by the time code
reader (time code signal reader).
Time codes are written into the sub-code area (data
area) on the helical track.
This enables the VTR’s playback to be read out from
the stop mode through slow-motion playback to high-
speed playback.
The time code value appears on the display or is
superimposed onto the screen.

User’s bit
Among the time code signals, the user’s bit refers to
the 32-bit (8-digit) information frame that is released to
the user. It can be used to record the operator
number or any other information.
The alphanumerics which can be used for the user’s
bit are numbers 0 through 9 and letters A, B, C, D, E
and F.
