Just what we need: even higher definition TV
Now that we finally have Comcast delivering high-definition television to our house (on a mere 8 or 10 channels since most channels haven't switched over to it yet), there's a new even higher definition TV being developed! According to this New York Times story (registration required):
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).
