I've actually started writing this blog twice already, and both times I got too buried in the technical bits and pieces that would literally interest only a true geek like me. In the first one I started writing about how 4K isn't really 4K, it's called UHD-1 which is slightly less resolution but it's still generally referred to as 4K in the consumer market, as true 4K is typically only used for cinematic purposes. In the second version, I pulled out most of the technical stuff but was getting too far away from the actual topic. I stopped writing and I started to think, what questions were people going to ask us? Most likely they will want to know by what factor is 4K better than HD?

UHD-1 is what you will find on many consumer televisions, while true 4K is found on most drones, including our Phantoms and Typhoons. The amount of data needed is quadruple what we need for HD, since 4K is four times the spatial resolution of HD. (Think about seeing 4 football fields on the screen instead of 1). (read mo
