Let me start by stating I'm very new to SDI video/distribution.
Setup:
Video Source - TONGVEO 20x Zoom Conference Room Camera (SDI Out 1080p/60) I could not find a specific model number, i did not order this. It's just what I have atm. I could not find any documentation to know whether this is level A or B.
Monitor Tester - Rsrteng HD-3200C
Camera SDI Out > 2' Belden 1694A Low Loss cable> Blackmagic Design Optical Fiber 12G> 300' SM 2strand Fiber w/ FieldCast 6G SFP> Blackmagic Design Optical Fiber 12G> 3' Belden 1694A Low Loss Cable> Blackmagic SDI Distribution 4k
Issue:
When I set the camera to output 1080p 60, i get no video signal out of the Distribution 4k, I get video signal off the Optical Fiber converter just before the Distribution 4k. I have swapped SDI test cables to make sure it's not a bad fitting or cable. If i dump the camera down to 1080p 30, I get video out of the Distribution 4k. I run into the same scenario if I use a Blackmagic Design Mini Converter SDI to HDMI 3G in place of the Distribution 4k and pull video off HDMI out. The video on the loop out is fine, but the HDMI out has no video.
We are also looking at extracting audio off this feed and will ultimately be coming off the 2nd optical fiber 12G into a Blackmagic Design Mini Converter SDI to Audio 4k then into the Distribution 4k. If i put this in, i do get 1080p 60 video signal on the loop out of the SDI to Audio 4k. It's only when i try to go thru the Distribution 4k or SDI to HDMI 3G.
I have updated the firmware/software of the SDI to HDMI 3G converters but didn't have mini usb cable on me to update the Distribution 4k
I definitely feel this might be a level A/B issue but not sure how to troubleshoot this further. Any suggestions or recommendations on what to try next?
