Time code & user’s bit

Time code

The time code signals generated by the time code generator (time code signal generator) are recorded on the tape, and their values are read by the time code reader (time code signal reader) to indicate absolute positions on the tape in increments of hours, minutes, seconds and frames.

The time code itself is written in the sub code area (data area) of the helical track.

This enables the VTR’s playback speed to be read from the stop mode to slow playback or even to high- speed playback.

The time code values are indicated on the display or superimposed onto the screen.

User’s bit

The user’s bit is a 32-bit (8-digit) information frame among the time code signals which has been released to users. 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 to 9 and the letters A, B, D, E and F.
