WHAT'S NEXT Just Like High-Definition TV, but With Higher Definition By DOUGLAS HEINGARTNER June 3, 2004 HIGH-DEFINITION television may be only just beginning to catch on, but researchers at the Japanese national broadcaster NHK are already working on a successor. The format, called Ultra High Definition Video, or UHDV, has a resolution 16 times greater than plain-old HDTV, and its stated goal is to achieve a level of sensory immersion that approximates actually being there. At a picture size of 7,680 by 4,320 pixels - that works out to 32 million pixels - UHDV's resolution trounces even high-end digital still cameras. HDTV, by comparison, has about two million pixels, and normal TV about 200,000 (and only 480 lines of horizontal resolution versus 4,000 with UHDV). Add to that UHDV's beefed-up refresh rate of 60 frames per second (twice that of conventional video), projected onto a 450-inch diagonal screen with more than 20 channels of audio, and you've got an impressive home theater on your hands. Of course, UHDV's current dimensions make it impractical for most homes. The NHK researchers are investigating how to squeeze all those pixels onto smaller screens. ... http://www.nytimes.com/2004/06/03/technology/circuits/03next.html ---------------------------------------------------------------------- You can UNSUBSCRIBE from the OpenDTV list in two ways: - Using the UNSUBSCRIBE command in your user configuration settings at FreeLists.org - By sending a message to: opendtv-request@xxxxxxxxxxxxx with the word unsubscribe in the subject line.
