Ultra HDTV

Ultra HDTV, or Super Hi-Vision, is an experimental video format conceptualized by the Japanese public broadcasting network, NHK.

Unlike standard HDTV, Ultra HDTV is four times as wide and four times as high, producing an astonishing 7,680 × 4,320 pixel resolution. Ultra HDTV is 16 times the pixel resolution of standard HDTV. Some believe that this new technology raises Ultra HDTV health concerns.

In addition to the significant upgrade in video quality, sound quality is also significantly increased with Ultra HDTV. 24 channels of audio can be used with 24 speakers, producing a difference comparable to the video resolution.

Currently, only 2 cameras are able to capture video in Ultra HDTV format, and can only capture about 20 minutes in a single day. Needless to say, our current infrastructure is not designed to meet the Ultra HDTV requirements.

Several sources suggest that Super Hi-Vision technology will be available within the next 15 years.
