DJI announced their new digital transmission system today which is capable of 1080p/60fps and which has been built with the new Ronin RS3 in mind, and while people on here won't really care for this particular product, it does prove what capabilities DJI could give us if they were to continue investing in the FPV market. Those antennas look very familiar  I guess we will just have to wait and see if they do end up producing and releasing a much smaller version in Air Unit / Air Unit Lite size based on this same technology that is aimed at the UAV market. They would clearly need to get the latency down for that though because 68ms or 100ms is just too much for FPV.

Notes

1. Measured with the equipment in a level and stationary state, the gimbal balanced, three axes in an active state, and the battery only powering the gimbal.
   
2. In open environments free of obstructions or interference.

I am assuming the VTX has a built in battery which makes is large n heavy.

Too big for our use case but hopefully the technology trickles down to FPV hobby grade stuff.

I guess for commercial applications they prefer the tradeoff of better image quality over latency.

68ms is no good for FPV agreed. If DJI do release their new FPV system later this year I'm hoping it will be at the 22ms mark or less with at least OLED 1080p120. Also with a 4K DVR would be nice with no slow SD card errors. Canvas mode and live audio too.

Good one ... 

Why is there not a low latency video receiver designed to hook up to a monitor instead of goggles from every digital goggle manufacturer it makes sense to do if it isn't potato quality analog

Having to buy goggles to receiver the video signal is mainly to lock you into their ecosystem and to force you to buy their most expensive hardware. The only HD system that currently has a module that you can hook up to a monitor is HDZero. The HD system coming from Orqa will also be a module if/when it finally gets released. Walksnail have asked the community if they are interested in a module and the reply was an outstanding yes, but whether they actually end up making one or not is anyone's guess at this point so all we can do is just wait and see what happens.

Interesting that the DJI version of the CE band is quoted in several places as 5725-5850, and not 5725-5875
