Time Code and User’s Bit

Time code

The time code signal generated by the time code generator is recorded on the tape as a time code, it is read out by the time code (signal) reader, and used to display the absolute position of the tape in increments of hours, minutes, seconds and frames.

The time code is written in the sub-code area (data area) of the helical track. For this reason, it can be read out across a wide range of VTR playback speeds from the stop mode to slow playback and to high-speed playback.

The time code is indicated by the display or by the figures superimposed onto the screen.

The figures 0 to 9 and the letters ABCDEF can be used for this bit.
