Apparently, the Divimath digital video transmission system does not support 1080p 60FPS.
I am therefore going to build a completely custom DIY solution using OpenHD. This will be a fun project!
I have just purchased two of the ALFA Network AWUS036ACH. One will be used as the air unit on the drone (VTX), and the other will be the ground unit that receives the video signal (VRX).
I can’t use the Raspberry Pi 4B to encode the video because it can’t do 60FPS, so I need a different SBC. Currently, I’m consider Rock 5B+. It even features a full sized HDMI input, so I can just plug the Sony FX3 directly into the port without having to use something like the BliKVM C790.
