Follow Metadata Config:
This section reports on Metadata presence if the
Follow Metadata
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.
•
The user can choose whether to use the available Dialnorm value in the downmix process by selecting ON or
OFF from the pulldown list at the bottom of the section.
5.5.5 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 encoded
audio (violet)
•
NPCM – the audio channel carries Dolby Digital Plus
or non-PCM other than Dolby E or Dolby Digital
(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 Auto Align
button to automatically adjust the audio timing delay to
ensure a perfect alignment with the video. This is
equivalent to changing manually the audio delay in the
audio processor. If you change the output timing of the
card or the video output format, you may have to re-
align the Dolby E.
•
The offset is not available for any type of audio other
than Dolby E.
