They say a giant 500 M-pixel screen is needed to approach reality
with faster frame refresh than even 60p (highest available today)

This will only accelerate the rush to a standard that NO analog converters will be made for. Since most BPC flat-screens in use today will fail by 2020 anyway, what's to stop the TV vendors (all foreign-made that will pump up the trade deficit) from fleecing us again?

Future displays will be economical OLED mass produced in lowest-cost country driving traditional manufacturers out of business.

Traditional manufacturers ARE out of business. Zenith, RCA, Philco, Sylvania, etc. When you see the old names on new product, it's just brand recycling. Once the marketing whizzes run their focus groups after us Boomers are gone, those names will likely disappear.

I really could care less about the foreign manufacturers. Most of them offshored their work from Japan, Germany, etc. long ago. They did their damage to America and deserve the same fate. Sauce for the goose...

The present downfall of Japan is very severe (shed a tear )
as consumers there now buy Samsung/LG.
Their mercantilist economy not diverse enough
to withstand this sea-change .

I saw this demonstrated at BBC Broadcasting House, London. A combined NHK/BBC team televised part of the olympics. Some live material and also recordings were relayed to screens in London, 2 other UK sites, 1 or 2 in the US and 2 in Japan.

I wasn't quite close enough to the (big) screen to see all the potential resolution but the results were impressive. Even under difficult lighting conditions (fireworks and heaven knows what else) the results were consistently excellent. The style was relaxed, mainly wide shots, with little panning or zooming. I think this style suits the system - imagine the horror of a big close up of somebody's face many time larger than life.

Will it happen in the home? I really don't know, houses in many parts of the world are too small to accommodate a screen big enough to do justice to the system.

Sometimes some at trade shows like CES you see prototype 4k screens
(unsuccessfully looking for the next badly needed money generating product to
keep mercantilist Japan afloat)

Like I said before, I think tv's are going to be thought of like cell phones, part of endless upgrade cycle. Already my 2Ghz PPC imac has been tracked off any further upgrades from apple, firefox, and the rest. My 1995 PowerMac 7600 200mhz machine I still use had its last upgrade to software in 2002, my new imac is a 2006.

This new HD will certainly not have a converter for any tube sets, possibly only a converter to HDMI only.

I wonder what the bandwidth of this new format will be? 32mb/sec? or would that have to be over 64mb/sec at the 120hz refresh rate...? I can't get over BBC HD being sent at 25fps..... That will surely blink on a tube tv, and even worse on a good lcd right? At those bit rates won't the broadcast channel BW be 2 to 4X today's new digital tv BW? I bet they will add more levels of mux. to the transmission like cell phones do so one channel can actually handle a few phones.

Or will it be too much to even think about broadcasting?

If the tv's are too expensive for home purchase I wonder if we well see local "movie theaters" like places around town to offer dinner and "ultimate tv" kinda like when movietone news was in the theaters. Anyone for Vampire sitcom's over dinner in town tonight on the 38' screen....? Ha-Ha what a future lay in store....

Ralph still didn't get his 3D tv perfected and were movin' on again....

Advances at this pace may even put a damper on early adopters.... I mean how often can you blow $10K on a new ultimate tv?

Funny enough, I just played some PAL video on a multi-sync TV the other day
And it flickered, but not for long, as Brain adjusts from 60hz to 50hz refresh rate.

Same happened when I went to England, TV's flickered, but only the first day.

That being said, 50 hz TVs would have been more "fatiguing" to watch as brain
has to work harder to mask low refresh/poor motion information.

But, watching PAL easier on brain in another respect: it's slightly higher
resolution (as low resolution also fatiguing to visual processing)

Flicker issue no longer exists as Euro TVs now refresh @ 100 hz

Flicker isn't an issue with LCDs as each pixel holds the previous brightness between refreshes. There is no decay as in a CRT. The downside of this is potentially greater movement blur.

European CRT sets mostly refreshed at 50Hz. A few high end sets at 100Hz. With current sets I'm not sure. Some claim high refresh rates, up to 200Hz, presumably with some kind of temporal interpolator. Some low end sets may still be refreshing at 60Hz with inferior interpolation. The result of this is horrible. The deinterlacing is pretty poor on these sets too.

As for HD transmission standards I think that 720/50p, 1080/50i and 1080/25p are all used in Europe. The 25Hz would be converted to at least 50Hz before display. This is very easy for progressive scan, the equivalent of a multiblade shutter in projected film.

I was impressed with the Sony Crystal Prototype TV
looks better than LCD (instant LED refresh) @ 240hz?

I refuse to have an LCD TV for this reason.
When I'm not watching my superlative 1965 21" RCA 'New Vista',
I will turn on the 2005 Samsung DLP w/LED: This has High intensity
LEDs that are flashed for RGB in sequence @120 frames/second.
There is no 'LCD' lag or filtering of the pure wide-spectrum LED light.
So picture has the snap of the Sony 'Crystal'- only this product is a
reality - unlike the Sony which is too expensive to mass produce.

Japanese acknowledge Amazing South Koreans who have:
The best Analog TV system : NTSC
The best Digital TV system : ASTC
The best TV Receiver : LED DLP
The best Smart Phone : Galaxy III
And best Pop Song : "Gangnam Style"
