Follow Metadata Config:
This section reports on Metadata presence in the selected path if the Follow Metadata Path 1 or 2 Operating Mode is
selected. The four data boxes below the Metadata status icon indicate the current mode, plus the values in use for
Dialnorm, Center Mix Level and Surround Mix Level.
5.6.3 AES Inputs tab
The status icons at the top of the tab indicate which Groups
and discrete AES are detected, and which of the 32 channels
have signal present.
Audio Proc Input Selection
This section provides a selection between the embedded
audio and the discrete AES inputs. Channels 1 to 8 will
always be the first 8 embedded channels. However, channels
9 to 16 can be either embedded channels 9 to 16 or the 8
discrete channels from the 4 AES inputs, selected using the
pulldown.
Sample Rate Converter
Use the pulldowns to select between OFF and Auto for each
of the four AES.
•
OFF:
Sample rate conversion is disabled. Use only
if the AES input is always 48 kHz synchronous
to the video input OR if the AES input carries
non-PCM audio (Dolby or other) with its
channel status indicating “Linear PCM”.
•
AUTO: Sample rate conversion is automatic, based
on the input audio type. Sample rate
conversion is enabled for PCM audio, and
bypassed for non-PCM audio.
5.6.4 Status
tab
The Status tab reports the type of audio present at the input
and the Dolby-E alignment.
Audio Type Status:
•
PCM – the audio channel carries PCM audio
(orange)
•
Dolby E – the audio channel carries Dolby E
encoded audio (blue)
•
AC3 – the audio channel carries Dolby Digital (AC-3)
encoded audio (violet)
•
NPCM – the audio channel carries non-PCM other
than Dolby E or Dolby Digital (AC-3) (yellow).
Dolby-E Alignment:
•
When Dolby-E audio is present, this panel will
display the offset/delay between the Dolby-E and the
video output timing of the card. You may click the
