You probably have heard quite a lot in the news
lately, especially if you are a television buff about HDTV (High Definition Television) or
DTV (Digital Television).
An Personal Historical Perspective
Some of you may have not been alive then, but in
1958/59, color TV had just made it's debut. My father was program director for KOA TV
channel 4 in Denver, Colorado when I was just a boy. He used to take me down to the local
studios on the weekends and I could watch film feeds of Sky King or participate in a local
kid's cartoon show. I remembered the quietness of the studios, the large TV cameras and
the hot vacuum tube transmitter area. Since NBC had
started broadcasting in color, and since my dad worked there, he was able to borrow a real
RCA color TV for a few months to test KOA's color broadcast capabilities. Now this was
probably the first commercial color TV and cost from $500 to $1000 (very expensive for the
1950's). Once in the privacy of our humble home, I watched my very first color broadcast:
The following program is brought to you in
living color on NBC: and a Peacock with primary/secondary colors appeared (not the correct
hues mind you)
With the TV's color started with
Bonanza!...the Cartwrights were never so colorful.
But alas, Hoss' face was blue and the sky was
pink. The colors were a wash - sorta like water colors; my dad and I spent the whole hour
trying to get the color/tint just right. The only other show in color was Walt Disney's
Wonderful World of Color. I must admit cartoons looked better in color than black and
white.
Other Networks like ABC
and CBS started to broadcast in color. Color commercials
came later and eventually, local television expanded from B&W to color in the
sixties...it wasn't until the 1970's had all local stations converted over to color,
almost 20 years since color debuted.
Color TV has come along way since then. It wasn't
until the late 1960's and early 1970's had it been perfected to the point that it was
quite acceptable. Early color TV's had green and pink lines on either side of objects on
the screen and local TV studios never seemed to have color matching in sync with other
networks so you had to constantly adjust the color...Today analog and
digital color TV is as perfect
as it can get. We even have stereo, surround sound and closed captioning...

television check out the New York Times
Enter HDTV or DTV...
the next generation in television will be like
a sequel to evolution of the Color TV..
"The following program is brought to you in High
Definition Digital Format on NBC..."
"CBS HDTV by Mitsubitsi"
1990 PREDICTION: HDTV will merge
with computers in the year 2000 and start to replace analog TV's; AT&T Satellite
Television and Zenith would develop this system...
AT&T was part owner of Direct TV and Zenith co-developed the HDTV standard that
will be used in the United States for digital television.
Note: Actually in the year 2000,
you can now buy an HDTV compatible TV tuner card for your PC from Hauppage.
Win-TV D
1997: Already, several local stations have started
broadcasting in test mode. HDTVs are expected to be available sometime in 1998, but only
if you are willing to spend $2,500-5,000! for those first units.
Six major cities will begin simulcast
broadcasting HDTV on separate channels/frequencies in 1998. By 2006, however, according to
FCC rules, all broadcasting will be digital and thereafter analog will discontinue. By
that time most HDTV systems will be well under $1,000.
2000 Update: When
this article was first written in 1996, HDTV was very new, and quite
expensive, most monitor/receivers around $5-10,000; but today the
cost is beginning to come down. Although there are still very few
HDTV broadcasts relatively speaking (compared to regular NTSC analog),
that is about to change. All major networks are starting to broadcast
several shows, like ABC's 780i, NBC's
Tonight Show in 1080i, CBS
and PBS and HBO. To date,
there are 122
stations broadcasting DTV. The dawn of a new age in television is at hand:
One can buy a system starting around $2,400. Although this is not
where the price-point will bottom-out, it puts it closer to reasonable
affordability.
Today Direct-TV now broadcasts several HDTV channels including an all HBO
HDTV channel. With RCA's new DT-100
receiver, costing around 649.00 connected to the new RCA
MM36100 monitor which
for now costs $2,299.00 (The monitor is a 36" multi-sync multimedia
(not wide-screen), tube based (not projection), interfaced to either an
outside terrestrial antenna or perhaps RCA's new Direct-TV plus compatible
elliptical HDTV satellite dish (DSA8900E)
for $199.00, you may not merely just see quite an improvement to regular
digital broadcasts, but you will be able to watch actual HDTV. Of course,
you could easily spend more for a system. Once the prices drop to
below 2,000 and more importantly, HD broadcasts begin to proliferate,
expect to sees sales take off (not unlike DVD
has). Note: if you don't get a HDTV system by 2006, you will have to buy
an adapter so you can continue to watch analog, because that's when the
channels you watch today will be disconnected...expect to see huge sales
in those adapters for the millions whom want to continue to watch
TV! I plan to purchase, install and experience the above
configuration over the next few months, so I will keep you posted...On
March 11th, it was delivered.
What problems are facing the early
adapters of this new technology and what caveats remain for it to become
mainstream?
- The number of HDTV broadcasts
are few and far between - but expect that to change from now on.
Direct TV now offers channels 509 for HBOH, a 24 hour HDTV based movie
channel. Channel 199 shows a half-hour demo loop of HDTV, and
late evenings/early mornings has PPV in HDTV. CBS has it's prime-time
lineup in HDTV while NBC only has Tonight Show, ABC lower resolution
sports...
- To receive over the air
broadcasts, you will probably need an outside UHF antenna. This will
permit you to watch the major network offerings.
- Compatibilities between
monitors and receivers, software and the differences between formats
are being worked out and standardized at this time
- Cable television may be the
last to adopt HDTV.
- Data-casting may subvert the
allocated spectrum for HDTV
