The problem is there's no way to control the HDMI receiver side - meaning recorder manufacturers do all kinds of strange things with the image (sharpening, color conversions, etc.) and in general only support very specific resolutions/framerates. There are also no standards for HDMI.

This PCB is relevant to the project because AXIOM Beta generates HDMI content inside its Beta Main Board FPGA and therefore almost any data can be sent over an HDMI connection. This provides a potential solution to not having control at the HDMI receiver side (recorder manufacturers do all kinds of strange things with the image, e.g. sharpening, colour conversions, etc... and in general only support very specific resolutions/frame-rates. Coincidentally there are also no standards for HDMI.

With the Elgato CAM Link 4k it's now possible to take over control of the receiver side. This opens up a whole world of possibilities with regards to what data could be packed into the HDMI "frame" if it were to be used as a data container.

1 PCB

It is reported to be an 8 layer PCB. Probably atleast a 2-3+ HDI.
