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.

Concepts like Super Hi-Vision have been discussed for almost 20 years now. The current 1920x1080 resolution is about as good as a human eye can resolve at a distance where the image occupies 30 degrees of our horizontal field of view--the same field of view which you'll find in the middle seat of most well designed movie theaters. That said, there are some advantages with regards to affective responses and time needed to create a sensation of reality by increasing the field of view occupied by the screen beyond that 30 degree standard. However, the primary gain in increasing the resolution four-fold would be in theatrical exhibition of feature movies, eliminating the film projection all together.

You're a moron. Nothing will replace film in the theaters for quite some time, if ever. Video just doesn't have the charm. Until they think of a way to make, nevermind, I think I'll keep that cat in the bag.

Thats cool but save your money. Pretty soon you will have a box in your livingroom that will be TV and Internet and you will have a Hologram that will let you interact. Voice commands will let you pull video from net in Hologram form. Cant figure out the interact part yet. Cable companies and telephone companies are paving the way as we speak with fibre optic to your house.

I have a 61" toshiba DLP that is clearer than I can see...almost. I also have a Direct tv HD tuner and a SD DVD recorder. I've found that when I record HD tv and play it back on the Toshiba the results are so good that I wont be buying a HD recorder till they give them away along with the media.. I also have a couple of DVD recorders that have the SD digital tuners in them and I am amazed at the resolution I get when playing them back on anything. I can read things and recognize people in the background...I could go on but I think you got the Idea.
