While Japanese broadcaster NHK demonstrated 8K technology way back in 2008 at CommunicAsia, but only recently developed a smaller and lower-power image sensor for eventual commercialization. Besides offering a staggering 7,680 x 4,320-pixel resolution, the new sensor can also capture extremely fast motion at 120-frames-per-second.
Two supporting electronic components have been jointly produced by NHK and Shizuoka University to keep up with the sheer amount of data recorded by the chip. One of them is a high-speed output circuit connected to the sensor, while the other is an analog-to-digital converter to digitally encode the video. (CNET)
