So I'm working on a new engineering project at work and I'm running into a bit of a roadblock.
We currently have a Media Studio that is running a BM ATEM 4 M/E, a BM 40x40 and a BM Talkback that is currently handling signal flow for Tally to some BM G2. Don't blame me, I didn't build the studio but I am fixing it. Lol.
I want to swap out the ATEM for one of the spare Carbonites that we have since it'll provide more of the features we need in the studio, which is 50% filming and 50% broadcast.
The current issue I am running into is I want to maintain the signal flow for the Tally on return SDI to the G2's, I want to remove the ATEM completely and swap it for the Carb. As it stands, the ATEM currently sends the Tally signal back through embedded SDI and I'm trying to find a solution that will convert the Carb's GPIO signal to embedded SDI. Real estate is at a premium currently and there's little chance I'll be able to run different cables.
I saw Skaathoj had a SDI-GPI link that would have worked exactly as I needed, but it seems as though they don't produce it anymore. I'm looking for alternatives that will do what I'm looking for. I know they have a ETH-GPI system, but I have no idea how I'd integrate that into the BM Talkback as I can't find any online documentation about it or have found anyone who's done something similar.
If anybody had info on how it would work that would be great. Other than that, different solutions would be appreciated also. If it helps any, the guys that run the studio do all of their shading in camera, they don't even use the BM software to shade so if I lose the ATEM completely, it will not effect our work flow.
