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.
