From Wikipedia, the free encyclopedia.
Super Hi-Vision, also known as Ultra High Definition Video or UHDV is a digital video format, currently proposed by NHK of Japan.
* Resolution: 7,680 × 4,320 pixels.
* Frame rate: 60 frame/s.
* 22.2-channel audio
o 9 - above ear level
o 10 - ear level
o 3 - below ear level
o 2 - low frequency effects
The new format is four times as wide and four times as high 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.
18 minutes of UHDV consumes 3.5 terabytes of data.
Preliminary response of the UHDV was somewhat negative. This was not because of the lack of the promised technology, but more in the fact that it was too good. Some viewers got motion sickness when viewing the video image. This was due to the fact that the image was so close to reality.
In November 2005 NHK demonstrated a live relay of Super Hi-Vision (UHDV) program over a distance of 260 km by a fiberoptic network. 24 gigabit speed was achieved using DWDM (dense wavelength division multiplex) method with a total of 16 different wavelength signals.
