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.
