<DIV>What you have to do is de embed the AES stream. Then modify it
and re embed it. Grass Valley had some modules in the MAX series that did
this. They appear on EBay a lot. The time delay will not be an issue
for this part of the process. The time delay to be concerned about is the
level processing that you require.</DIV>

<DIV>I'm trying to solve a problem involving an SD-SDI signal with embedded
digital audio: We need to be able to adjust the audio level within the
stream before it hits any other downstream devices.</DIV>
<DIV><BR></DIV>
<DIV>The level adjustment can't cause any picture to sound sync issues or
degrade the picture or sound quality.</DIV>
<DIV><BR></DIV>
<DIV>Any idea whether there's such a product out there?</DIV>
<DIV><BR></DIV>
<DIV>A small box solution would be ideal, rather than a rack-mounted device.
Rack cards in an independent, single-card housing with inboard or wall-wart
power supply is fine.</DIV>
<DIV><BR></DIV>
<DIV>I'll be contacting Ensemble and Cobalt again to see if they've
introduced something in the last 12-18 months</DIV>
<DIV><BR></DIV>
<DIV>If you are aware of something from either or other manufacturers,
please contact me off-list at <B><A

<DIV>New thought: A combination of boxes could work: IE: Dis-embed the
audio, allow for level control, re-embed the audio.</DIV></BLOCKQUOTE>
