HDTV Already Obsolete?
So you've followed our advice and have decided to ditch that dusty old set and spend the dough for a giant new HDTV. You'll be happy (or not so much) to know that researchers in Japan have completed the first revision of what may be HDTV's successor: Super Hi-Vision. The new technology is capable of capturing a broadcast image at a resolution of 7,680x4320. Compared to today's highest-resolution sets, which display images at 1920x1080, Super Hi-Vision features 16 times the resolution. To give you an idea just how clear that is: At a Super Hi-Vision demonstration, a newspaper was held up about 10 feet away from a prototype Super Hi-Vision camera. Its text was clearly legible.
There are problems, of course. Video at this resolution requires a huge amount of bandwidth that today's television, cable, and Internet networks can't handle. It'll be many years before researchers and engineers hand us the bandwidth to overcome those hurdles, and many more years after that when you'll need to worry about going TV shopping again.
