Time Codes and User’s Bit
Time codes
Time codes are used when recording time code signals generated by the time code generator
on the tape, reading out their values with the time code reader, and displaying the absolute
positions of the tape in increments of hours, minutes, seconds and frames.
The time codes are written in the sub-code area (data area) of the helical track. For this reason,
they can be read at any playback speed from the stop mode to slow-motion playback or high-
speed playback.
The time code value is indicated on the display or superimposed.

User’s bit
The user’s bit is the 32-bit (8-digit) data frame in the time code signal which is made available to
users. It can record operator numbers, etc.
The characters which can be used for the user’s bit are 0 to 9 and A B C D E F.
