We’re in the same boat as you here – with a few slight differences. We have a small OB van where the switcher lives and cable runs of about 50m to our cameras (currently 3x Sony EX1R). We’ve tried HDMI over ethernet with no luck…works with short ethernet cables (3-5m) but no longer. We’ve also tried with long HDMI cables. The TVS is very fussy. Also please be aware that the computer has to be outputting whatever resolution the switcher is set to, otherwise it won’t show… In our case, here in the uk its set to 1920x1080i50.

I’ve even tried VGA to HDMI convertors but those are just flawed by design. The computer thinks its a VGA monitor that’s connected and won’t offer you the option of 1920×1080. With a HDMI connection from the computer we’re able to get the right resolution but then still have the distance to conquer…

Our next idea is to try to convert from HDMI to SDI, carry the signal over Coax and either go into the TVS via SDI or convert back to HDMI… Atomos have just launched some ‘cheaper’ convertors. Will keep you posted if we have any luck.
