Is there a product that brings the digital HD video signal of Lightbridge to regular DIY quads?

I would like to use the higher quality and the “always on or off” aspect that comes with digital video transmission, but I also want the freedom to build my own quad. DJI’s Lightbridge seemed like a good idea, but I don’t see any comparable products made for regular DIY quads. Does something like this exist or is literally every company only making the analog signal transmitters?

I know that using this method is not suitable for “racing quads” as it adds a small delay, and I am completely fine with that. I wouldn’t say that I’d be using my quad for aerial photography, but I certainly won’t be using it for racing either.
