Synchronizing the internal time code generator to an external time code

Make these settings to synchronize the internal time code generators of multiple VTRs, or to record the playback time code signal of an external VTR without waveform attenuation.

1 To synchronize the internal time code generator to external LTC

Connect the TIME CODE IN connector to an external time code generator or the time code output connector of an external VTR.

To synchronize the internal time code generator to VITC of the input video signals

Select the input video signals by pressing the [F1] (VIDEO IN) button in the PF1 menu.

2 Set the following function buttons as shown below:

[F6] (TCG SOURCE) button: To ext.

[F7] (TCG MODE) button: To regen (regenerate).

[F10] (VITC) button: To on when recording VITC.

[F5] (TC SEL) button: To LTC when synchronizing to LTC. Set to VITC when synchronizing to VITC.

When the settings have been completed, the internal time code generator starts operating in synchronization with the external time code generator.

The following table shows the conditions specified by the various settings of the [F6] (TCG SOURCE) and [F7] (TCG MODE) buttons.

To check the running of the internal time code generator

Press the STOP button to stop the VTR, then press the REC 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) (DVW-A500/1 and 500/1 only)

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.)

Note

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