4.4 Troubleshooting Metadata Problems
The DP570 has several status indicators to help troubleshoot metadata‐related problems.
The front‐panel status display shows the metadata source as External if any metadata
source is set to external.
Metadata Input indicators on both the DP570 front panel and in the DolbyRemote 570
software provide status information. The indicators are green any time a valid metadata
signal is present, whether or not it is being used. They turn red only when an external port
is in use and there is a problem with the metadata signal.
The Metadata Params submenu under either the Setup or status menu on the
front‐panel display can also be used to determine the current source for a parameter and
its current value.
4.5 Outputting Metadata
You can choose to send metadata from the DP570 to downstream devices using the
Metadata Output connector on the rear panel. The frame rate for output metadata is set by
the received video reference signal and is locked to the beginning of the video frame.
Note: If the DP570 is using external metadata and there is a temporary error in the
metadata stream, the unit continues to use the last valid metadata values. When
the error clears, the DP570 resumes using the stream from the external port.
