FS1 Installation and Operation Manual — 4.3 Embed Audio Out
4.3 Embed Audio Out
This parameter allows you to enable or disable audio output. SDI Embedded Audio
output may be
On
,
Muted
(embedded silence) or turned
Off
(no embedded audio).
Analog and AES audio outputs are not affected by 4.3 (they’re left On).
4.4 Sample Rate Convert
This parameter controls audio sample rate conversion on input audio.
On
is the default
(audio is rate-converted and synced with video) and
Off
is a setting for use when Dolby
®
5.1 and similar schemes need to be preserved and the audio data passed unaltered.
Normally, set this to
On
(default). Set it to
Off
only if the following are both true:
1.
You want to pass digital encoded audio from either embedded or AES into
embedded and/or AES out.
2.
You have the embedded or AES input genlocked to the FS1 output. In other
words, the encoded audio will not survive the frame-sync function (dropping or
repeating frames) so it needs to be set to lock to the input. You can lock to a
reference only if that reference is driving both the FS1 and the upstream source
of the embedded or AES input to the FS1.
Note:
If parameter 4.5
Audio Follow Video
is set to
On
, the
Sample Rate Convert
selection is independently kept for each separate input:
SDI 1
,
SDI 2
,
Composite
,
S-Video
,
and
Component
. If
Audio Follow Video
is set to
Off
, another
Sample Rate Convert
selection is used.
4.3 Embed Audio Out
Description of Choices
Parameter Adjustments:
On (
Default)
Off
Mute
Embedded audio will be passed.
Do not pass embedded audio packets to the SDI outputs.
FS1 outputs SDI embedded audio packets containing silence.
4.4 Sample Rate Conversion
Description of Choices
Parameter Adjustments:
On
(Default)
Off
Normal operation. The FS1 performs audio sample rate conversion and keeps the
video and audio synchronized.
The FS1 does not sample rate convert the audio, leaving embedded audio as is,
useful for Dolby
®
5.1 embedded audio and other applications.
