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.

Setting the time code

1 Set the VTR to the menu mode.

(Set the LOCAL/MENU/REMOTE switch to the MENU position.)
