Image Sensors 2012 interviews Hiroshi Shimamoto who will present NHK 8K/120fps sensor on the upcoming conference. Few quotes:
"Super Hi-Vision (SHV) is a future broadcast system that will give viewers a great sensation of reality. SHV consists of an extremely high-resolution (16 times of HDTV) imagery system and 22.2 channel super surround multi-channel sound system.
We are now proposing to extend its frame frequency from 60 Hz to 120 Hz to improve the motion picture quality, and to have a wide-gamut colorimetry for better color reproduction. We call this new SHV system "full-spec SHV"."
