HDTV/DTV

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 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..."
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.
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...
Today AT&T is part owner of Direct TV and Zenith co-developed the HDTV standard that
will be used in the United States for digital television.
