Audio embedding / de-embedding

[mrpackethead]

I'm wondering if any one has seen any schematics / applicaiton notes, for embedding and de-embedding Audio on SDI Video?

I have an applicqaiton where i want to pull the audio out well before it gets to the video processing.  I also need to be able to inject it backin.

The usual approach is an FPGA with at least one transceiver to do the embed/deembed and an LMH something or other to act as line equaliser and driver, but IIRC Genem/Semtech had a part that specifically did audio embed/deembed but it will be ancient by now, might be worth asking about it still.

I would have thought that a very modest Artix 7 would get it done with no fuss, we use the -35s but we also do video and scaling in there, so something smaller may well work for you.

Thanks..  Thats a good place to look.  Semtech appear to have a few useful chipsets!
