The 3G receivers apparently have a built in 4K scaler that can be used to convert 2160p (4K) content to 1080p for display on 1080p HDMI 1.x monitors or projectors and scale a 1080p image to 2160p for display on a 4K-capable screen. The built-in scaler has HDCP handling that enables all content to be shown on any display regardless of its resolution and HDCP version.

One of the interesting approaches that Just Add Power is using with this is that they market that “unlike other IP-based video distribution products, there is no mandatory upgrade to 10 Gigabit managed switches required” — basically, they are using compression to do what they do, so there’s a trade-off. While 3G is compatible with fiber networks, you can still integrate the 3G transmitters and receivers over a standard Cat 5e/6 cabling and a Gigabit managed switch infrastructure to create a 4K-capable HDMI video matrix of any size, from 2×2 to 4,000×65,000, that allows for easy distribution of HDMI 2.0 devices to non-HDMI 2.0 displays and vice versa. Their 3G products also support uncompressed multi-channel audio formats including Dolby Atmos, compressed multi-channel audio and stereo.

Here are all the detailed specs.
