Super Hi-Vision, also known as Ultra High Definition Video or UHDV and UHD is a digital video (http://en.wikipedia.org/wiki/Video) format, currently proposed by NHK (http://en.wikipedia.org/wiki/NHK) of Japan (http://en.wikipedia.org/wiki/Japan).
Super Hi-Vision's main specifications:
Resolution: 7,680 × 4,320 pixels (16:9) (approximately 33 megapixels)
Frame rate: 60 frame/s.
Audio: 22.2 channels (http://en.wikipedia.org/wiki/22.2)
9 — above ear level
10 — ear level
3 — below ear level
2 — low frequency effects
Bandwidth: 21 GHz frequency band
600 MHz, 500~6600 Mbit/s bandwidth The new format with a resolution of 7,680 × 4,320 pixels is four times as wide and four times as high (for a total of 16 times the pixel (http://en.wikipedia.org/wiki/Pixel) resolution (http://en.wikipedia.org/wiki/Screen_resolution)) as existing HDTV (http://en.wikipedia.org/wiki/High-definition_television), which has a maximum resolution of 1920 × 1080 pixels. Because this format is highly experimental, NHK researchers had to build their own prototype from scratch. In the system demonstrated in September 2003 (http://en.wikipedia.org/wiki/2003) they used an array of 16 HDTV recorders to capture the 18-minute-long test footage. The camera itself was built with four 2.5 inch (64 mm) CCDs (http://en.wikipedia.org/wiki/Charge-coupled_device) with a combined resolution of only 3840 × 2048. They then resorted to pixel shifting (http://en.wikipedia.org/w/index.php?title=Pixel_shifting&action=edit) to bring it to 7680 × 4320.
To put this into contrast, the human eye sees, at apparently, around 4000-5000p at its focal point. So this really would be the future... if they could push the size down to 30 inches of course... otherwise its just like a bunch of hd tvs selotaped together :/
