Time Code Input

This parameter controls where the DP571 derives its time code information.

LTC:LTC In connector supplies time code.

VITC: Vertical Interval Time Code is derived from the Video Ref In connector.

Metadata Revert

This parameter determines what happens if the external metadata source is interrupted. These settings are only active if the Metadata Source is set to External or Ext Override.

Stop Encoding: Stops encoding and displays error status on front-panel Error LED. Most likely useful only in postproduction.

Last Used: Continues encoding using the last values set by the external source.

Preset: If any metadata parameters are missing, the Program Config selected in Metadata Params: Reversion Preset is used but no Dolby Digital metadata is included in the Dolby E bitstream. See Section 3.2.4 - Metadata Params.

Adaptive: Behaves like Last Used if the metadata disappears completely. Behaves like Preset if any metadata parameters are missing.
