How Fox Is Using 4K at the Super Bowl

How Fox Is Using 4K at the Super Bowl | Video Breakthroughs | Scoop.it

The age of 4K may have officially begun, but the world still has some catching up to do. Case in point: You can't actually watch this weekend's Super Bowl in 4K (a.k.a. Ultra HD), even if you have a 4K TV, since there isn't yet a broadcast or cable standard for ultra-high-def format. Even the live stream is "just" in 720p.


That doesn't mean 4K won't make a difference at the big game. Fox will have six 4K cameras at MetLife Stadium — two on the sidelines, two on the goal lines and two on the end lines — specifically for the network's "Super Zoom" feature. When the broadcast needs to get in tight on some action, the feed will crop a 720p "window" from the 4K picture captured by those cameras. That way, Fox can get tight, high-res images without needing to zoom in optically.

NHK tests 8K terrestrial television transmissions

NHK tests 8K terrestrial television transmissions | Video Breakthroughs | Scoop.it

While the rest of the world is wondering about when we will see 4K broadcasts, NHK in Japan is conducting test transmissions of 8K Super Hi-Vision signals over the air. Its latest test demonstrated a signal with 16 times the resolution of high-definition sent over a single terrestrial television channel.

The standards for Ultra-High-Definition or UHDTV include both 8K and 4K profiles. An 8K Super Hi-Vision image has a resolution of 7680×4320 pixels, or over 33 megapixels, which is four times the resolution of a 4K or 3840×2160 image, or 16 times the resolution of a full-frame high-definition picture.


In its latest test, at the research laboratories of NHK in Hitoyoshi in southern Japan, an 8K signal was transmitted over a standard 6MHz broadcast channel and received 27 kilometres away.
