For the past several years I have been helping goHDR man their booth in the futures park of NAB, the siggraph of the broadcast TV tech nerd industry (it fills up the Vegas convention center). goHDR was the first to my knowledge to have a full HDR pipeline from camera to compressed transmission to display, and that is what got me interested in the company in the first place. The goHDR booth setup from this year is in this video.
In previous years the industry was obsessed with 4K (what I call 2160p) and the HDR demo got little attention, and my impression was the broadcasters didn't know what HDR stood for. This year was entirely different as the industry is looking for some new reason to ever buy a TV again. In my opinion, HDR is more impressive subjectively than was digital, HD, or especially 2160p (I want that for coding, but do not find the entertainment demos compelling). Only the transition from B/W to color was subjectively more impressive to me than HDR is (yes, sadly I am old enough to remember that). Scott Wilkinson wrote a nice little piece on HDR at NAB this year and notes that HDR is finally on the horizon.
