Configuring Alarms
Detailed Directions
Audio Format
The format of each audio channel (PCM, Dolby AC-3, Dolby E, other or Unavailable) is
reported as a text attribute, that can be assigned to a text level within a logical source.
Metadata
The metadata extracted from the VANC and from the Dolby E is available as text in the XEdit
hierarchical system list, and therefore can be exposed via any layout element capable of
displaying text levels from logical sources (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.
Logical Source Assignment
Logical source assignment is performed by dragging an AES pair onto a logical source’s
audio level.
For Dolby E, if the AES pair is calibrated as a Dolby E source, then the 8 channels are
available to be displayed by an audio monitor. The channel displayed by the audio monitor
depends on how the monitor was configured.
For Dolby VANC, if the audio monitor is set to Auto or Dolby VANC, the VANC metadata
from the video of the assigned AES will be decoded. The audio monitor will have access to
all amended audio peaks depending on VANC program configuration (regardless of which
AES pair was assigned to the logical source).
