Embedded 1, 2 In Audio
Enables or disables automatic phase
adjustment for FS1/FS2 input embedded
audio channel groups.
Enable: Automatic adjustment (normal
setting)
Disable: No adjustment
Auto
Sync SDI
Audio Clock
Selects audio clock signal to use for
de-embedding and processing audio data
in HD-SDI input signal.
Auto: De-embeds HD-SDI embedded
audio data using the audio clock phase
data in the embedded audio. Synchronous
and asynchronous embedded audio
signals from 4 audio groups can be
de-embedded separately.
*2
Audio data will be processed as
synchronous data if the audio clock phase
data is incorrect, or jitter is too great.
Sync SDI: All audio data in 4 audio groups
are always processed as synchronous data
without referring to the respective audio
clock phase data.
*3
Audio Clock: Always uses audio clock
phase data in HD-SDI embedded audio
data to de-embed the audio data.
*4
*1 Embedded audio signal groups are automatically phase-adjusted when they are input to
the FA-9520. If there is an abnormal audio signal in an audio group, whether the audio
group is in use or not, audio streams may be obstructed by the auto phase adjustment. In
such cases, audio stream obstruction can be avoided using this Alignment enable/disable
function.
*2 Embedded audio signals in SD-SDI video inputs are always processed as synchronous
signals.
*3 Sync SDI should be selected only if audio data cannot pass through as Auto or
asynchronous audio data is never input.
*4 Audio Clock may be effective in the case audio data cannot properly pass through as Auto
or Sync SDI.
Use this Alignment enable/disable function only if the audio output has noise or is
muted. Do not change the setting for normal audio output.
Note that the audio output will be temporally muted when Alignment is changed from
Disable to Enable while audio signal phases are aligning.
