Скачать или смотреть FPV Goggles, Eachine EV300D and a few words of insight!

I have had the Eachine EV300D goggles for a bit now, I thought this would make a nice intro to FPV and how it can integrate to a number of different applications including industrial and other areas.
What it did was raise far more questions than It answered, dont get me wrong, these are nice goggles for the price, Banggood were great to send them and I will be working through many projects and tutorials on how they work etc. But..... it appears they are nearly all (Not just the Eachine) based on really old NTSC/PAL TV standards, not just that but odd ones that are rarely used ?? AKA 480P and 576P, also when it comes to the Cameras, dont believe all the numbers...
