Time code/user 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 slow-motion playback up to high-speed play (approx. 50a normal speed/approx. 100a when using DVCPRO tape).

The time code value appears on the counter display. It is also superimposed onto the display of the TV monitor which has been connected to the VIDEO OUT 3 connector or SDI OUT 3 connector, but it does not appear on the front panel’s LCD monitor.

User bit

“User 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 values to be recorded.

The alphanumeric characters which can be used for the user bit are the figures 0 to 9 and the letters A to F.

Setting the internal time code

1 Set the VTR to stop mode.

2 Select “TC” using the COUNTER button.

3 Use the TC (REC RUN/FREE RUN) switch to set the operation mode in which the internal time code generator is to be advanced.

REC RUN:

The internal time code generator is advanced during recording.

The time code advances all the time when the TC (REGEN/PRESET) switch is at the REGEN position.

FREE RUN:

When the power is on, the internal time code generator is advanced regardless of the operation mode.

4 Use the TC (REGEN/PRESET) switch to set the re- generating mode.

REGEN:

In this mode, the continuity of the original time code prior to editing is maintained.

O A more detailed setting can be performed using setup menu No. 503 (TCG REGEN) and No. 504 (REGEN MODE).

PRESET:

In this mode, recording is commenced from the value which was set by the (SHIFT+PLAYER).
