Beyond HDTV
The Hub writes "The Economist writes a thoughtful article about the next generation of HDTVs and how they will provide resolutions beyond 1080p. The drive for higher resolution is driven in part by the demands of 3D content. Also, some see streaming higher resolution content to the home as a way to make up for declining DVD sales. This would mean the studios would have to better embrace services such as Netflix or stream directly to the consumer. Mind you, picture quality is driven by more than the number of pixels."
I would venture to guess that 80%-90% of the people buying HDTV's are doing it either because their old TV broke and it's the only thing available, or because they heard it was cool from a friend and wanted it for their Superbowl party. Either way, almost no one really understands it or even knows how to get the most out of all that resolution as it is NOW. We're talking people who buy 32" HDTV's and sit 10 feet away from them, thinking they're getting "high definition." We're talking people who hook up DVD (and even blu-ray) players to their HDTV's with composite cables. We're talking people who still have the same SD cable box they've had for years, thinking that the channels "really look better now in HD."
Joe isn't even ready for 1080p. This whole "let's add even MORE resolution" thing is just industry hype. It's Sony and Samsung thinking that if they just keep adding new gimmicks that people will constantly trade up their TV's like they trade up their computers. Joe Sixpack already has a perfectly good HDTV that he isn't even using to its full potential as it is, but they want him to go out and buy a TV with a resolution that he would need a magnifying glass to even appreciate. Welcome to America!
SJW: Someone who has run out of real oppression, and has to fake it.
Computer monitors have been following television resolutions & aspect ratios. We need height back in our displays for all the portrait document-oriented stuff that we spend the majority of our times with on computers (emails, webpages, word processing, heck even board-based casual games). I'm sick of seeing my interactive options through a narrow slit.
Few sources, even Blu-Ray, consistently deliver 1080p now. Get close enough to a display to see the pixels, and notice the compression blur that stabilizes once motion stops.
The next logical step is a higher frame rate. 24FPS for movies is way too slow. Cameron ("Titanic", "Avatar", etc.) has been bitching about this for years. He likes pans over highly detailed backgrounds, which produce strobing effects at 24FPS. Movies should be at least 48FPS, and maybe 72FPS. (The Showscan tests indicate that viewers notice improved quality up to about 72FPS, but not above that, so that's the limit of human perception.)
Personally, I'd like to see framefree compression. This is a concept out of Kerner Optical (a Lucasfilm spinoff). Instead of merely switching from one frame to the next, the player computes a morph between frames. This allows running at any display rate, allows arbitrarily slow motion, allows much higher compression ratios than MPEG-4, and requires substantial computation in the decoder. They never did much with the technology, though; it was sold to Monolith in Japan, which hasn't done much with it. It's worth looking at again, now that putting a GPU in a TV isn't a radical concept.
And the misconceptions shown in that chart is exactly why we cant have nicer resolutions. That chart details the normal resolving capability of the human eye (one arcminute). The lines he drew there indicate when a person with 20/20 vision would be able to fully resolve each pixel. It does not account that a significant amount of the population can naturally see better than that, nor does it account for the fact that another significant amount of the population wears corrective lenses to see better than that. It does not account for the fact that certain structures like two parallel high contrast lines can be resolved significantly smaller than that. It does not account for the fact that structures smaller than that can still produce visible aliasing artifacts.
Basically, someone somewhere took a couple minutes to find out the meaning of "20/20 vision" and decided that's all the better we ever need, without realizing that the human eye is far more complex than that single value depicts.
