NHK Fukuoka Broadcasting Bureau. Credit: Soramimi Japan's national public broadcasting organization NHK is developing an 8K slow-motion camera capable of recording ultra-high-definition content at 240fps.
The technology was announced in a press release (partially translated here), and will be showcased at NAB 2018 in Las Vegas next week. Though 8K monitors and televisions are still in their infancy, the broadcaster is pioneering 8K technologies in anticipation of future demand.
To that end, NHK also plans to showcase a new 8K VR display during NAB 2018. The display is designed to eliminate the pixelated look common to current VR headsets.

Finally, future 8K broadcasts may benefit from the NHK's new transmitter technology, which reduces an 8K broadcast from a huge 40Gbps to a more manageable (but still huge) 8Gbps. The transmitter then converts the content into an IP-based signal for live broadcasting, a process that allegedly happens in "tens of microseconds. "
According to AV Watch, NHK anticipates using its new 8K technology for sports broadcasts (think Tokyo 2020 Olympics) and other content featuring fast-moving objects starting later this year. Unlike existing solutions, the NHK system is said to offer better compression and transmission for a very low delay while maintaining 8K quality for live shows.
