It seems that as soon as we get settled with our 720p and 1080p HDTV displays, talk started up about even higher resolution images. Demonstrations of 2K and 4K display technologies have knocked viewers’ virtual socks off. Is there a limit to how high “high definition” can become?
One problem that doesn’t get discussed much, however, [...]
Folks,
I hate to admit this...but I bought it ....until i went down to the comments....GOOD job & Happy April Fools Day!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I was hoping for the system they use on CSI TV Shows. They can take a 320x240 VHS tape and zoom/sharpen to a super high resolution image.
It's on a TV show, so it MUST be true!!!

Yes, Bob, they've been using incredible computers to do this magic for years, mostly on spy shows. Also cool is how they can use low-res cams with snap-shot capabilities in ATMs and such to scan large areas with real-time video, which they helpfully store hours of in kilobytes of RAM. Amazing stuff.
The problem that poor Alfred had was in explaining how we vectorize the data in the first place. Minor issue. And the size, cost, and complexity required to restore it back to a raster format. But they've got some amazing GPUs now that will be usable not only to render the data into imagery on our big screens, but can also be used to heat the home! That's great for winter-time viewing, but not so good for summers. However, a combination of Peltier junctions and liquid cooling (also used to provide hot water for showers) should solve that problem by next April 1.
On April 3rd, as I began to read the column, I was with you. The explanation was initially easy to follow, or so it foolishly seemed. Still, it seemed too good to be true. But, when you began the arcane bit with the straight lines representing images and the mathematical equations, well, you lost me. Then, I was trying to sort it all out. I didn't get it. You really got me.
Alfred's comments are pretty close to reality. Tektronix of Portland, OR built vector scan display terminals for many years for use in CAD, graphic design, mapping and many other applications. They were monochrome green, not too fast and required specific software but you could find many thousands of them all over the world. Most radar displays are vector scanned with long persistence phosphors. I have seen television on very slow decay phosphors and it is not something you would want to watch.
SMPTE is a very active organization. If you want technical, they are the place to go! Actually if you would like to consider4K and above consider attending DCS 2011 NAB - SMPTE at the Las Vegas Convention Center - Advances in Image and Sound: 3D, 4K, and Beyond
Sunday, April 10, 2011:
"This will involve examination of the psychophysical and subjective impacts of moving to 4K, 8K,
and higher resolutions, as well as consideration of creative, technical, and practical issues."
Panelists:
· George Joblove, EVP, Advanced Technology, Sony Pictures Technologies
· Michael Goi, President, ASC
· Howard Lukk, VP Digital Production, Disney
I don't know anything about the "Brooklyn Bridge" organization however.
