What
if the Pig is Grace Kelly or Robert Redford? Or Outing American
TV's Dirty Little Secret: NTSC Video
By Bill Warner
Amidst
the current buzz about HDTV and the looming switch to digital television,
one thing is perfectly clear: American television broadcasts are
lousy. No, I don't mean the programs; they're an easy target. Instead,
I'm referring to the quality of the picture we receive on our home
television sets. If you take a close look at what we're given at
home in the U.S., you'll be appalled to see the visual stew of sloppiness
that we're subjected to.
For example, ghosts(ing); fuzziness (very poor resolution); interference
artifacts; pucks, tennis balls, golf balls, baseballs and footballs
that momentarily disappear; unrealistic color; and many others.
But
as anyone who has traveled to Europe and watched much television
there (in many countries, they only break for commercials at the
bottom and top of each hour, so it's way easier to watch a film
broadcast over a commercial network in Europe) can tell you, we've
been getting the short end of the stick in the U.S. for years. The
fact is, the American television technical standard, known as NTSC,
is an ugly kluge of technical compromise and industry apathy that
produces pictures barely worth watching. For starters, television
in Europe is roughly 20 percent higher resolution than what we see
in the U.S. (The Europeans' PAL or SECAM standards give 625 lines
per screen, not the 525 provided via our NTSC). And the color, especially
on the French system (which the technical guys all like to make
fun of but which provides an excellent picture), is superb.
If
you're not familiar with European television, there's another way
to see what you're missing. Sit down at any run-of-the-mill computer
monitor and take a close look at some video images, still or moving.
What do you see? More detail and resolution than what your 27-inch
NTSC monstrosity can give you. Why? Well, two reasons, mainly: first,
your computer monitor displays data by design with higher resolution
than your TV set can.
And secondly, American television uses what is called an interlaced
display, meaning that it only shows half of its 525 lines at a time.
First it displays the odd lines of the picture display, and then
the even ones. Because of the persistence characteristics of human
vision, your eye retains the first image even after it has been
replaced by the second. You perceive the whole picture even though
technically at any given 1/30th of a second interval only half the
picture (roughly 250 lines) is on screen.
With
a computer monitor, what you see is what's really there: all the
lines of the picture are present the entire time you are perceiving
the image. You see all 480 lines, refreshed every 1/60th of a second.
The result? You get a crisper, clearer image than the lowest- common-denominator
picture you get with your standard American television set. And
if you really want to get a hint of what's to come, take a look
at one of your graphic designer friends' 17- or 19-inch monitors.
You'll see vivid color and picture detail that your 27-inch or bigger
set does not show.
The
European television systems and computer monitors give only a suggestion
of what we can have if we demand more as consumers. If you've got
any doubts about whether the move to digital and HDTV is worth it,
squelch them now. Virtually everyone who experiences true HDTV and
surround sound says the combination is "stop-you-dead-in-your-tracks"
beautiful.
The
ultimate goal of the HDTV standard has been to produce a picture
and sound experience comparable to 35mm pictures. However, as Greg
Coyle points out in "The Uncertain Revolution of HDTV, or a
Pig in a Dress is Still a Pig," if the programming remains
the same, there's no reason to convert to digital.
But
the point is that the programming will change, and for a couple
of reasons. First, there's an axiom in the TV biz that "you
shoot for the display." This means that we don't see programming
whose overall visual effects and level of detail can't be depicted
on the standard TV screen. Why bother shooting what you can't show?
But with HDTV, directors and writers will have options that aren't
currently available, such as long shots, crowd scenes, wide-angle
views, up-close details of buildings, statuary, sculpture, and paintings.
If it can be shown, it will be.
Second,
for a couple of years, certain organizations have been shooting
some of their programs in both conventional and HDTV formats. There
is already a lot of programming on the shelves waiting to be re-shown
or shown for the first time when HDTV arrives. Certain sports events
have already been broadcast and shown in HDTV, such as major league
baseball and major world soccer matches. Ever watch the Travel Channel?
Think what it would be like in HDTV. Or, how about a film like "Out
Of Africa," or "A River Runs Through It"? Sports,
nature shows, travel, first-run movies will all be available in
HDTV eventually.
Still
not convinced? How about the ability to choose whichever world network's
coverage you like best for major sporting events, such as Grand
Slam tennis tournaments? (Geez, the American announcers never shut
up. Listen to the Brits or the Germans: they stop talking when points
are in progress.) How about access to first-class films (not movies)
from all over the world, not just what the Hollywood studios will
allow into their very limited foreign distribution channels in the
U.S.? How about watching the French Grand Prix Formula 1 race or
the Tour De France from the cameras mounted on the cars or bicycles
of your favorite competitors (say four)? Or, live HDTV broadcasts
of first-run plays from London? We will eventually have options
like these. Where we'll find the time to watch them is another issue.
Now
that you know what you're missing, what can you do to get the manufacturers
to change? The good news in this conversion to digital television
is that we consumers have the potential to force the television
industry to convert to digital TV, and eventually HDTV, faster than
they otherwise will. The fact is that right now consumers have unbelievable
leverage in the marketplace. So here's how to exert that leverage
and get the picture (sorry, but for now, I can't do anything about
the programming) we deserve. (See HDTV Advocate for a supportive,
proactive consumerist view on the whole HDTV biz.)
For
starters, demand your birthright: Let companies know that you want
audio and visual quality at a level near the limits of your senses.
Every one of us can help spur the acceleration of HDTV product introductions
by holding off our purchases of video products until HDTV-capable
versions are available. Start saving your money now. Don't buy any
more low-resolution products. You should be very reluctant to buy
NTSC-based products that you will be depressed to see after viewing
the HDTV displays at the local electronics stores. Companies will
notice and produce real HDTV products before you are too old to
enjoy them. Those of you in the top 10 markets should keep in mind
that HDTV broadcasts are mandated to begin in a little more than
six-months, so digital video will soon be a reality for you.
I know,
I know, the sets and set-top boxes seem expensive. But that's typical
of consumer electronics products at the early stages of market development.
Prices will drop, just as they have for personal computers. Initially,
a couple hundred bucks for access to the digital stuff coming our
way with picture quality slightly better than what we get via NTSC
analog isn't a bad deal at all. And the sooner we stop buying standard
NTSC television sets, the sooner the manufacturers will change and
begin offering HDTV-capable equipment.
