Most of us are still mulling over our choices to enter the wonderful world of HDTV, but experiments are already underway to push pixel progress even further out. Last month, NHK showed a live demonstration of “Super Hi-Vision” TV at the 2005 World Exposition in Aichi, Japan. The images had a resolution of 7,680 by 4,320 pixels, which is more than 15 times as many pixels than a 1080p display. It took two 8 megapixel digital cinema cameras to provide the feed, and the uncompressed signal required a 24 gigabit-per-second transmission rate.
That may seem extreme, but now consider the HIPerWall (which is short for Highly Interactive Parallelized Display Wall). (No, I don’t see how they got to that contraction, either.) The 23 foot wide and 9 foot tall display is installed at the University of California Irvine, using 50 individual flat panel displays. Total resolution is 200 million pixels, or the equivalent of about 100 1080p HD displays. Each of the 50 panels has its own dual-processor computer driving the image.
Now, doesn’t a 60-inch 1080p TV for your home seem like a perfectly reasonable display by comparison?
