Procedure for time code synchronization

To synchronize the time code, proceed as follows:

Synchronizing the time code

1 Turn on the POWER switch.

2 Set the PRESET/REGEN/CLOCK switch to PRESET.

3 Set the F-RUN/SET/R-RUN switch to F-RUN.

4 Set the DISPLAY switch to TC.

5 Supply a time code signal and a reference video signal complying with the SMPTE (for the DVW-970) or EBU (for the DVW-970P) standard and in proper phase relationship, to the TC IN connector and to the GENLOCK IN connector, respectively.

This operation synchronizes the internal time code generator with the external time code. After about 10 seconds, you can disconnect the external time code without losing the synchronization. However, there will be noise on the recorded image if you connect or disconnect the time code signal during recording.

Notes

•When you finish the above procedure, the internal time code is immediately synchronized with the external time code and the counter display will show the value of the external time code. However, wait for a few seconds until the sync generator stabilizes before recording.

•If the frequency of the reference video signal is not the same as the frame frequency of the camcorder, the camera cannot be correctly genlocked. In such a case, the internal time code is not correctly synchronized with the external time code.

•When the GENLOCK ON/OFF item is set to “OFF” on the GENLOCK page of the MAINTENANCE menu, the time code cannot be synchronized with the reference video signal. In this case, set the GENLOCK item to “ON” on the GENLOCK page of the MAINTENANCE menu.

User bit settings during time code synchronization

When the time code is synchronized, only the time data is synchronized with the external time code value. Therefore, the user bits can have their own settings for each camcorder.

To synchronize the user bits with external user bit data, set the EXT-LK UBIT item on the TIME CODE page of the MAINTENANCE menu to “EXT.”

To release the time code synchronization

First disconnect the external time code, then set the F- RUN/SET/R-RUN switch to R-RUN.

To change the power supply from the battery pack to an external power supply during time code synchronization

To maintain a continuous power supply, connect the external power supply to the DC IN connector before removing the battery pack. You may lose time code synchronization if you remove the battery pack first.

Camera synchronization during time code synchronization

During time code synchronization, the camera is genlocked to the reference video signal input from the GENLOCK IN connector.
