camera control with HDMI signal boosters in line?

PostTue Feb 16, 2021 4:54 pm

I'm setting up a system in a recording studio environment where I'll need to connect BMPCC 4Ks in recording rooms to an ATEM Mini Pro Iso in a control room. HDMI lines will be going through wall panels, and I'm concerned about signal integrity and reliability for both video signal as well as camera control. Would HDMI signal boosters be recommended in this scenario, and will camera control data be passed through?

'Till now, I've only run video around the place via SDI which has worked well, and I had originally thought that I'd just convert the camera output to SDI for longer runs and reconvert to HDMI at the Atem. But I'd really love to preserve camera control if possible...

I supsect it will depend on the model of HDMI booster - it would have to pass the control signals in the reverse direction to the video signal.

Have you considered a pair of BM Bidirectional SDI / HDMI micro converters? Must be the recent model with 3G in the name and you need a pair of SDI cables between them. (The second cable transmits the control data from the ATEM mini.) There is a diagram on page 22 of the Convertors manual.

Thanks to some googling and forum searching (which OBV I should've done before I posted this!), I found a fiber HDMI cable which I can run through the wall from control room to recording room and which works both for picture and camera control.

Progress!!

The Linkinperk cables of amazon also do the job but are much cheaper :-)
