Remember the Osborn? Or was it the Osborne?
Actually, I knew it existed, but didn't
care. This thing was a personal computer.
Like we'd ever need one of those? Those
new electric typewriters with memory were
the rage. THAT was something!
Flash forward and we are upon the reverse
engineered UFO goodies. Oh, wait, no,
that's not exactly right.
It's the dawning of the age of Aquarius,
age of Aquarius, Ah QUAR EEEE USSS. Um,
no, that was some time ago.
It's the age of $3 US Gas. Not a good
milestone
The age of HDTV!!! Remember when "high
definition" included the terms "stems
and seeds?" You do? You rascal.
No, this is about High Definition TELEVISION.
Personally, I feel the word TELEVISON
is so.. Fifties. We need a new one there.
So did you jump for the Plasma? Or the
LCD projector? The DLP? Have you got the
home theater with all the tricked out
electronics?
Don't put your ear directly on the high
tech train tracks, then, because there's
another train coming, and you'll hear
it down the line.
UHDV is in the pipeline. On the track.
In the lab. In the electron wind. Want
to guess? Time's up. ULTRA HIGH DEFINITION.
Remember the movie where they invent
this skull cap that would capture your
emotions and immediately the bad guy looped
someone having how shall we say - some
very intense happy times. and turned himself
into peak experience broccoli? Is that
where all this is headed? Not for a while,
if ever. HOWEVER: UHDV is close to the
detail of 35mm film. With 7680 x 4320
pixels, this isn't far from the 4K (4,000
scan line) digital projection systems
for big-screen movie theaters.
Donald Trump will be able to see how
bad his hair looks like never before.
UHDV features 33 million pixels with
a 60 frame-per-second (fps) progressive
scan format.
NHK, the Japanese broadcasting giant
who had HDTV in the 1980s. is behind the
UHDV format, but reassures us it may be
a long time before home theater UHDV becomes
reality. That's corporate talk for, "Don't
let the competition know how close we
really are!"
With 32 times the bandwidth demands of
HDTV, UHDV would be prohibitive for today's
broadcast, cable and satellite technology.
NHK's demo required a data rate of 24
Gbps. That was a few years back in Amsterdam
where some people were close to hurling
lunch because the moving car video hi-jinx
was that real.
How real?
NHK cobbled together a custom camera
of four CCD image sensors; then to show
the output built a LCoS projector combining
four eight-megapixel panels. Data storage,
using 16 synchronized HDTV recorders,
provided roughly 18 minutes of recording
time, using 3.5 terabytes of total capacity
and a screen about 12 feet high and 22
feet wide. NHK researchers called this
"the sensation of reality saturation point,"
in the hopes of providing a completely
immersive experience: 100 degrees of visual
field angle, viewing from a distance of
three-quarters of the height of the screen
(about nine feet) with at least 60 pixels
required for each one degree of visual
field angle.
And speakers? UHDV offers 24-channel
sound, or 22.2, containing vertically
arrayed surround sound speakers: nine
above ear level, 10 at ear level, three
below ear level and two low-frequency
subwoofer channels.
The format, according to NHK, is not
so much intended for home use as for museums,
public spaces and theaters. You tell The
Donald.
Once upon a time there was SHOWSCAN.
Special effects pioneer Douglas Trumbull
had his demo unit in a suburb of Dallas,
behind a Chucky Cheese, if memory serves.
I saw the demo.
The equipment and the Showscan Film Process
of producing and projecting Showscan films
are justifiably proprietary and patented.
At the time, Showscan's discovery was
hailed as the most significant advancement
in film technology since the introduction
of sound in the 1929 film "The Jazz Singer".
(Not the one with Neil Diamond.) However,
it remained as little more than a technological
curiosity until the company developed
new camera, high speed projectors, and
built special theaters to showcase the
revolutionary Showscan images. There was
a catch-22 at work. Theaters weren't equipped
for this state of the art projection so
they couldn't convince investors to make
films in that format. Solution: do it
all in house.
I can't remember the specs but it was
scarily real, 3-D, multi channel and way
ahead of multi channel. or HDTV. I do
remember it ran film through the gate
much faster than normal projection speeds.
Today the company's simulation and specialty
theatres are open or under construction
in 24 countries around the world, located
in theme parks, motion picture multiplexes,
expos, world's fairs, resorts, shopping
centers, casinos, museums, and other tourist
destinations where somebody wants a rush.
If NHK can even come close, well.
Enjoy your puny HDTV now while you can,
citizen.
