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.
