Tuesday, July 29, 20080 comments

Ultra HD (Ultra High Definition), also called UHDV (Ultra High Definition Video) and Super Hi-Vision, is a digital video format proposed by the Japanese research group and broadcasting company, NHK (Nippon Hoso Kyokai) Science and Technical Research Laboratories.

Ultra HD is a giant leap forward from HDTV. It provides a video resolution that contains 16 times more pixels than a conventional HDTV. That is, against 1,080 lines of resolution of HDTV, Ultra HD offers 4,320. More precisely, Ultra HD provides 7,680 x 4,320 pixels in a widescreen aspect ratio of 16x9, for a total 33 megapixels. Additionally, Ultra HD offers a 22.2 channel sound system as opposed the 5-6 channel surround-sound systems commonly available with HDTVs.

Ultra HD is not planned to be commercially available until 2025. Until then, technology junkies will have to be satisfied with the standard HDTV.
