Starting with trials set to start in the Olympics in London in Aug this year, ITU has finally set the standards for UHDTV. UHDTV comprises 4k and 8k standards. ITU also redefined ITU-R standards like Rec.709 1080p to support 1080p on 16:9 aspect ratio and added additional standards for frame rates.
The ITU standards are different from the present standards for digital cameras and computers. Youtube uses 4096x3072, instead of the 3840x2160 (formerly known as quadHD), so it'll take a bit of firmware upgrade to conform with the new standards (or they'll want you to buy a new camera!)
The most significant of these standards is the 120 frame rate for both 4k and 8k, which means for broadcasters will have to have bandwidth of up to 320x what is available now! Problem is all broadcasters now on have 720p or 1080i bandwidth, and not even 1080p!
I remember as a kid watching a HDTV demo at Wimbledon (specifically a Lendl vs Edberg match). I almost skipped live to watch the match on the HDTV. With development time from R&D to market standard now shrinking, it is estimated that UHDTV will only be in the mainstream after 10-15 years. But it does tell us of what is coming, and for those who shoot 4k stock, to bug your camera manufacturer for an update to conform to the new standards!

"8K RAW (8192 x 4320), 24fps, 10-bit: 1.012 Gigabytes per second 60.75 Gigabytes per minute 3.645 Terabytes per hour"...LOL...now that's HBR. :lol:
