Japanese national broadcaster NHK has said it is developing a sensor capable of shooting 8k video at 120fps. It will be able to support the company's Super Hi-Vision standard of 7680x4320 pixels (generically known as UHDTV) which, at 33MP, is 16x higher resolution than current 1080 HD technology. The high-speed chip is being developed with Shizuoka University and was reported at the IEEE Internation Solid-State Circuit Conference currently taking place in San Francisco. (via The Verge)

UHDTV is expected to arrive in homes some time around 2020 (the first screens have been demoed) and a 60fps version will be used to show high-quality footage from the 2012 Olympics on a series of large screens around the UK.

NHK has a history of developing high-resolution broadcast technologies - having started producing HD content as far back as 1982. Previous 60fps 8K cameras developed by NHK have been based around multiple 4k chips from Aptina.
