UHDV resolution shown in comparison to other digital video formats Super Hi-Vision, also known as Ultra High Definition Video, UHDV, Ultra High Definition Television, UHDTV and UHD is an experimental digital video format, currently proposed by NHK of 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 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 resolution) as existing HDTV, 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 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 with a combined resolution of only 3840 × 2048. They then resorted to pixel shifting to bring it to 7680 × 4320. The system was demonstrated at Expo 2005, Aichi, Japan, the NAB 2006 and NAB 2007 conferences, Las Vegas, and at IBC 2006, Amsterdam, Netherlands. A review of the NAB 2006 demo was published in a Broadcast Engineering e-newsletter.[2] In November 2005 NHK demonstrated a live relay of Super Hi-Vision (UHDV) program over a distance of 260 km by a fiber optic network. Using dense wavelength division multiplex (DWDM), 24 gigabit speed was achieved with a total of 16 different wavelength signals. |

That's too much detail. I like my current non-HD, non-Digital-signal TV. |

Imagine watching porn in UHD. You'd see every wrinkle and birthmark. |
