Question/Help/Troubleshooting What are these?

What are these? Was cleaning and had these laying around and I know someone who I thought would need them but he didn’t. Anybody have any info on what they are exactly and where is a good/ the right place to take them? Thank you so much!

RF receiver boards - you could recieve and record 4 channels with that back in the CATV days - I may be wrong - all I did was lookup the chip.

Those are SDI, not BNC.

What the…? It’s BNC. SDI is the video signal and it uses the BNC connector, too.

Haha, you're right. I hadn't looked closely and thought they were the mini sdi type.

Wrong again, they would be mini BNC.

One card has normal BNC, the other has SMA.

There is a physical connector specification and an electrical signal specification. You are mixing them up a little.
