What is Ultra HDTV?
In the world of super video television, there’s high-definition television (HDTV) and then there’s ultra HDTV, sometimes referred to as true HDTV, full HDTV, or super high res. Ultra HDTV is obviously better than HDTV, and they are both better than traditional television, in terms of resolution. HDTV is advanced video technology that drives what amounts to a much sharper, clearer, and ultimately more colorful picture than in most traditional TV displays, or standard definition TVs (SDTVs). HDTV is all the rage these days, as people line up to buy larger and larger televisions on which to view sports, films, and other pursuits. Many of these larger televisions have HDTV. By and large, HDTV offers a picture of a higher resolution than traditional displays. With resolution, the larger the number, the better the picture on the screen. That is the more lines, or the more pixels, the sharper and better the picture. Traditional TVs offer resolutions of up to 480 lines. HDTV can display resolu
In the world of super video television, there’s high-definition television (HDTV) and then there’s Ultra HDTV. One is obviously better than the other, and they are both better than most current television displays. HDTV is advanced video technology that drives what amounts to a much sharper, clearer, and ultimately more colorful picture than in most traditional TV displays. HDTV is all the rage these days, as people line up to buy larger and larger televisions on which to view sports, films, and other pursuits. Many of these larger televisions have HDTV. By and large, HDTV offers a picture of a higher resolution than traditional displays. With resolution, the larger the number, the better the picture on the screen. Traditional TVs offer resolutions from 300 up to 500 and 600 pixels per inch (PPI). The more pixels per inch, the sharper and better the picture. HDTV can display resolutions of 720 up to 1080 PPI. These are significant upgrades to existing technology. In order to take advan
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.
