Time code and user’s bit

Time code

The time code is used when the time code signal generated by the time code generator (time code signal generator) is to be recorded on the tape, its values are to be read by the time code reader (time code signal reader), and the absolute position of the

tape is to be displayed in increments		of	hours,
minutes, seconds and frames.
The time code is written in the sub-code area (data
area) of the helical track. This enables insert editing
to be conducted independently using the time code
alone. In addition, the VTR’s playback speed can be
read from the stop mode to the slow motion playback
up to high-speed playback (approx. 50			k normal
speed or approx. 100	k normal	speed	when using a
DVCPRO tape).

The time code values are indicated on the display and superimposed display.

REGEN:

The continuity of the underlying time code in place prior to editing is maintained.

PRE:

The time code can be preset using the operation panel controls or remote controller.

AUTO:

The time code is automatically switched to REGEN

or PRE depending on the VTR’s operation mode: during editing, REGEN is selected; at all other

times, PRE is selected.

User’s bit

The “user’s bit” refers to the 32-bit (8-digit) data frame among the time code signals which has been released

to users. It enables operator numbers and other values to be recorded.

The alphanumerics which can be used for the user’s bit are number 0 to 9 and letters A to F.
