4-3-3 Setting the Time Code Generator (TCG SOURCE/MODE)

There are two ways to record time codes on the VTR. One way is to record the output of the VTR’s internal time code generator. The other is to directly record time codes that are input from an external time code generator.

The output from the internal time code generator can either be set to a specified initial value, or synchronized with an external time code generator. The internal time code generator time code settings are made with the [F6] (TCG SOURCE)/[F7] (TCG MODE) buttons. Menu selections and settings are shown below.

Regenerated signals are selected using the 608.TCG/ UBG REGENE MODE setting in the VTR SETUP menu.

To check the running of the internal time code generatorPress the INPUT CHECK button.

4-3-4 Selecting the Time Code Running Mode (RUN MODE)

Press the [F8] (RUN MODE) button to select the time code running mode.

free: The time code advances when the power is on regardless of the VTR’s operation mode.

rec: The time code advances only during recording.

4-3-5 Selecting the Drop Frame Mode (DF/NDF)

Press the [F9] (DF/NDF) button to select the running mode for the CTL counter and the time code generator.

DF: Drop frame mode1) (DF is displayed.)NDF: Non-drop frame mode2) (NDF is displayed.)

auto: The unit switches to drop frame mode when the field frequency is 59.94 Hz, and switches to non- drop frame mode when the field frequency is

60 Hz.

Note

This setting is only active when the frame frequency of the unit is 29.97 Hz or 30 Hz.

When the [F7] (TCG MODE) button is set to regene, the drop frame mode is inoperative since the time code generator is synchronized to the playback time code.

1)Drop frame mode

In order to compensate for differences between time code values from the time code generator and the actual time that occurs when the field frequency of this unit is 59.94 Hz, the drop frame mode causes the time code generator to omit the first two frames (frame 00 and 01) in each minute except the tenth.

2)Non-drop frame mode

In this mode, drop frame mode processing is not performed. Since there is no frame cutting, a discrepancy of about 86 seconds occurs each day (in the case of a field frequency of 59.94 Hz).
