Definitions
Audio Format
The format of each audio channel is reported (PCM, Dolby AC-3, Dolby E, other or Unavailable).
Metadata
The metadata extracted from the VANC and from the Dolby E is available as text in the XEdit system tree,
and therefore can be displayed in any widget capable of displaying the text element of channels (currently
only UMDs).
Dialnorm is displayed as a numeric value between -31 and -1 dB. Program Config is displayed as the Dolby
E Program Config description. Unavailable is displayed if the source is not being decoded, or is not Dolby E.
Configuring Video/Audio Alarm Threshold
To configure the threshold for a video or audio alarm:
1. Click the System tab in the main window.
2. On the Configure menu, click Connect, if you wish to apply the changes in real time. If the connection
succeeds, “Connected to [IP address]” will appear in the application status bar.
Note: If this step is omitted, then you will need to export the database to apply the calibration
changes.
