DVD Multitrack Recorder DV824

Chasing external TC (the optional Model 8348 required)

The following explains how to chase-sync the unit to time code received from the [TIME CODE INPUT] connector when the optional TC/SYNC card (Model 8348) is installed.

In the following connection example, a VTR is a master, while the DV824 (with the Model 8348) is a slave. The DV824 receives time code recorded on the master VTR and chase the master. A word sync reference signal is also fed to the DV824 from the master VTR.

Preparations

Before performing the chase function, set the following.

1)Set the system clock reference to "Video".

You can set the system clock reference via the quick setup mode or the "Sync clock" menu item in the "TC SETUP" menu of the MENU mode (see pages 47 and 127).

2)Set the chase mode appropriately.

You can set the chase mode via the "Chase mode" menu item in the "TC SETUP" menu of the MENU mode (see page 135). Three chase modes ("Once", "Continue" and "Frame sync") are available. The default is "Once".

3)Set chase offset if required.

By setting chase offset appropriately, the unit chases and locks to the master with maintaining a time interval.

You can set chase offset via the "Chase offset" menu item in the "TC SETUP" menu of the MENU mode (see page 136).

Chasing

1)Starts playback of the master (in this example, VTR).

2)Press the DV824 [CHASE] key to activate the chase mode (the [CHASE] indicator starts flashing).

The DV824 chases the master time code. When lock is achieved, it starts playback while the [CHASE] indicator is lit steadily.

3)To stop chasing, press the [CHASE] key again (the [CHASE] indicator turns off).
