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).
A 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:
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...

Enter HDTV or DTV...
the next generation in television will be like a sequel to evolution of the Color TV..
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?
