Fifty Years of Color Television 469

Posted by michael from the get-off-the-couch dept.
peter303 writes "The Houston Chronicle notes that color TVs were first manufactured on March 25, 1954 at a price of $1000 (about $4000 in today's dollars). Some of the older folk here remember the excitement of your first neighbors acquiring one of these in the 1960s and as the TV series one-by-one switched to color. Ironically, for such a high tech nation, there hasn't been a major quality improvement in TV broadcast images for a half-century until the 2006 changeover to HDTV."

    Adults are projected to watch, on average, 1,669 hours of television in 2004, about 70 days worth, according to census figures.

    1669 hours... a perspective:

    If you are awake 16 hours per day 1669 hours is 104 days, not "just" 70. Apparently, on average, adults watch TV 29% of their waking hours. If you work/commute 45 hours per week, your "free time" is, if you do nothing else, about 9 1/2 hours per day, of which, on average, you watch TV 4 1/2 hours.

    So the average adult uses more than half of their available time watching TV.

    Pretty sad.

    Actually, there have been numerous quality improvements, though they have come in the receivers, rather than in the NTSC standard. The standard itself is rather elegant, and apart from the error that resulted in shifting to a non-integer frame rate (and the problems that has created for designers of hardware for decades), it has proved very robust.
    • and apart from the error that resulted in shifting to a non-integer frame rate

      What is a non-integer frame rate? Do you mean the Horizontal and Vertical Scans out of sync with each other? Or is one or the other a strange multiple of the carrier wave? Or what?
      • Many people refer to television's refresh rate as 30 frames per second, but the truth is that the refresh rate is 29.97 frames per second.
      • IIRC, NTSC runs at 59.94 fields per second or thereabouts. It is NOT 60 fields per second, otherwise you get one noticable glitch about once every twenty seconds.
        • So, the framerate isn't an integer multiple of some arbitrarily chosen units? That doesn't sound like a problem with the framerate. It sounds like a problem with the units chosen.

            Actually, the problem is that the frame rate is not an exact integer multiple of the 60Hz AC power frequency, which is usually the largest source of electrical noise. It's off by a fraction of a percent; that's why you often see a distortion slowly creeping up the screen about once per minute as the frame rate beats against the power line sine wave. If the frame rate were exactly locked to the power line frequency, the distortion wouldn't move, so you wouldn't notice it.

            IIRC, the original B&W broadcast was at 60 frames/second, but there was some technical reason they had to slightly shift it in order to add the color subcarrier. Old B&W TVs were the worst with this noise distortion because they weren't designed to try to prevent it.

            (I think that color TVs only became truly usable in the 80s when they introduced decent automatic color correction. Before that, it seemed you could only watch in one of two colors: purple or green. No matter how much you fiddled with the knobs on old color TVs, it never looked quite right.)

              Uhhh... Okay. Credentials: Former professional video technician (at the SkyDome in Toronto) before being hired to design radar video systems for Litton. Also an avid collector and restorer of early television sets. [glowingplate.com]

              In the 1950s, AC power was not universal, especially in rural areas (note the sustained popularity of the "All American Five" AC/DC table radio at that time). Lots of places had DC, and lots of cities had 25Hz power well into the late 1950s. Nor was it necessarily going to be in sync from one town to the next, so you couldn't guarantee that the 60Hz powerline hum could be synchronized with the TV station's 60Hz vertical signal. In other words, you couldn't be guaranteed that the hum was going to happen in the vertical blanking interval (that black bar you see rolling when the vertical hold control is set wrong).

              I suspect that the vertical was chosen to be at 60Hz more because the large current draw of the vertical output tube driving the deflection yoke would then be more likely to occur during the charge cycle of the set's filter capacitors, allowing smaller capacitors to be used (cheaper). This of course being a time when electrolytic filter capacitors (in fact, all small parts) were still hand made.

              Even more importantly, you should remember that most early TV sets (until the advent of selenium rectifiers in about 1955) had full-wave rectifiers, generally using a 5U4 or similar tube. A full-wave rectifier folds the negative half of the sinewave up to the positive side, which effectively doubles the frequency to 120Hz.

              Either way, if the set is operating correctly, regardless of color standard, you will not see any powerline artifacts or ripple. It's when the horizontal system starts to come out of resonance that the biggest current draw happens in the set. Your horizontal output tube (transistor) consumes the most power of any part of the set; if a typical 1950s DuMont or Admiral has a cathode current of 120mA (at ~300V) and you misadjust the horizontal hold, that current will spike to over double that. That will load down the set's power supply, discharge the filter capacitors more, and you might start to hear 120Hz (full wave rectifier at 60Hz) hum in the set's speaker.

              IIRC, the original B&W broadcast was at 60 frames/second, but there was some technical reason they had to slightly shift it in order to add the color subcarrier.

              Yup. The original NTSC standard was 30FPS; when the 3.58MHz sinewave which carries color was added, the bandwidth of the signal had to be increased. (The original was 3.5MHz bandwidth for the image; reducing the frame rate slightly was sufficient to keep the bandwidth inside the original spectrum and didn't screw up many of the existing TV sets.)

              Old B&W TVs were the worst with this noise distortion because they weren't designed to try to prevent it.

              Note that the NTSC color TV standard was adopted in 1953, though not implemented until 50 years ago today. Every TV set built since then has known about the new frame rate the sets would have to handle. I actively collect and restore early TV sets, and I only have a few which predate this - they're rate.

              Again, you don't get powerline beat in the picture unless something is wrong with the set's filter capacitors.

              If you're getting a beat in the picture which, on a blank raster, moves in time with the vertical hold control, then you've got a problem where the vertical is either consuming too much current, or a

        What is a non-integer frame rate?

        The frame rate in monochrome television was 30fps. In NTSC, it is 29.97fps. This leads to the need for "drop-frame" timecode, and other delights.

        Drop-frame attempts to correct for the time errors by dropping two frame addresses periodically. The algorithm is that the first frame of the first second of each minute not evenly divisible by ten is identified as frame 2, not frame 0. The 18 frames per 10 minutes thus dropped reduces the cumulative error to a little more than 2 frames per 24 hours.

        There are other techniques recommended for reducing the residual further.

      I wouldn't go so far as to call NTSC "elegent", though it is clever especially with regards to how it implemented colour. PAL is a much cleaner standard, as the europeans (as they often did) took what they saw as flaws in NTSC and implemented things differently. Though PAL has a lower frame rate (25 as apposed to 30), it has a higher resolution and doesn't requier a TINT or HUE control, and the colour is better. When there are problems in the signal, with PAL you will see weaker colour, but with NTSC you can see the wrong colour (ie "green faces"). SECAM (the french standard) is even better because it uses FM modulation for colour, so it eliminates both these problems, though it has its issues (you can't "mix" two SECAM signals together, which makes it a pain for some professionals).

          That definition was declared by the Brits, and SECAM was also defined as Something Essentially Contrary to the American Method.

          I've worked in television for over 30 years, and although there are certainly shortcomings in the NTSC standard, they are dwarfed by the failings in the delivery systems (transmitters and cable systems), so that the resolution visible in the living room has typically been about 50% of that seen in production rooms.

      You have to work harder to pay the increased cable bill as channels have to pay to buy new equipment. Then you have to work harder still to afford the new TV to receive the signals. Then you have to get a car big enough to carry said new TV from the store to your house. Then you have to haul it around and get it in a place where your wife (or SO) approves so it follows the flow of the room.

My biggest beef at the moment is the number of broadcasters who slap a watermark right in the middle of the black lines thus confusing my TV so it can't stretch the image properly. Yes, I can use one of the manual presets but then it chops off the edges.

    I think TV has more to do with what is ON it, not what is IN the TV electronics.

    Programming quality has greatly improved since even the 1980s, and so has the picture/colour too, in my opinion. The cameras are sharper, and don't produce as many streaks when they move in dim areas.

    The quality of the TV electronics has declined if anything. Now that they are made in Mexico, instead of places where quality was a desirable feature, I hear lots of people complaining they die within a year. Plasma TVs for instace only have a lifespan at maximum of about 7 years, compared to I suppose ~15 for CRTs. I have two working 20" colour TVs that are both at least 15 years old.

    I would rather watch a fuzzy show I like, than a sharp/crystal clear show of some tiresome comedy like Everybody Hate Raymond.

    To say that there have been no major quality improvements in color television isn't entirely correct. The televisions themselves have implemented better and better filtering algorithms and can better lock onto signals than they used to. Color realism has gotten better with newer TV's to project more fleshy tones and more accurate color temperatures.

    Then there have been improvements in the means of broadcasting signals. Cable TV was introduced, and not too long after was followed by satellite reception (with their appropriate receivers), both of which improved the strength of the signal and integrity of the image. In more recent years, digital cable and satellite hit it big, and allow for near-perfect signal quality and picture integrity.

    The only thing that hasn't really changed up to this point has been the resolution, and this has partly been a result of how well the TV market took off after its introduction. It's hard to change a standard once it has been in place and is used by everyone. Optimally, it would be nice if there was a way to allow HDTV signals to continue to be received by regular definition TVs so that broadcasters wouldn't have to maintain separate equipment, but the technology is so much different that it would be impractical. This is why the introduction of HDTV has taken so long.

      Interesting - I just want to expand on your "fleshy" point:

      Modern TVs use a colour gamut designed to improved flesh tones, yet they have a smaller gamut than the original colour specification. In other words, an antique original colour TV is able to represent MORE colours than your current set.. It just won't do hiqh quality pr0n as well.

      As to "near-perfect" signal quality and picture integrity... I would argue that "digital" mpeg encoding reduces quality. The mpeg encode of course relies on "picture integrity" (actually, no, everything is bundled up into 188 byte packets, with the assumption that there will be lossage, and no retransmission).

      As to resolution - 480i has been "good enough". Indeed, DVDs are 480i/p as well. Generally, few complaints.

      1080i (etc.) HD formats. ARE a major step. Roughly, an order of magnitude improvement. But, for many, 480i/p is "good enough" (please note that HD has 6 times the datarate of a current DVD - and DVD *is not* an HDTV format. The only source of HD will be broadcast (possibly cable or sat..). And, you won't actually be able to *record* an HD signal using normal consumer gear).

      And, I find that 480i/p is good enough for me. I do have a largish set, and still don't really have the urge for HDTV. If we had "super-DVD" out there, with 1080i format movies, THEN I would for it. But, I honestly don't care for broadcast formats.

      That's probably just me, though...

    Ironically, for such a high tech nation, there hasn't been a major quality improvement in TV broadcast images for a half-century until the 2006 changeover to HDTV.

    Assuming HDTV actually switches over in 2006...

    I would argue that there were two major quality improvements in TV with the advents of video tape and digital compression. The first was a revolution of time, since people could now watch what they wanted when they wanted regardless of when the stations/theaters were showing it. The second enabled a revolution in distribution, as it allows cleaner transmission in smaller channels and arbitrary additional content. This is mainly manifested in DVD but is equally applicable to digital cable, video on demand, and online distribution (legal or otherwise, with anime fansubs and other non-domestic shows being the most striking application). Thanks to digital tech you can bundle on a ton of extras, edit with ease, and lower the cost of distribution and replication to inconsequential levels.

    HDTV is a nice improvement in video quality to theater-grade levels. But the video and digital revolutions are far more significant, and will continue to trump HD where both can not be accomodated. After all, what matters the most is not the presentation but content.

    Nothing highlights the amazing cost that has been aquiring HDTV like this.

    $1000 then / $4000 now for the first round of color TVs?

    It was something like $10000-20000 for the first round of HDTVs. In the last year they were just now coming down to the $4000 range, especially if you count the cost of the HDTV tuner as part of the TV cost.

    Today you can get them for sub-$1000 but not with a tuner so far, which puts it at a minimum of $1200 for full HDTV.

    How long did it take before the broadcast networks considered color to be "it"? I know in the early 80's I was still watching on a B&W tv about 1/2 the time. -Good- color quality didn't really happen until the late 80's.

    That is 30 years for a full transition.

    Makes the time it has taken to get HDTV adopted (2 years before it is considered defacto, probably 10 more before you get rid of the majority of old color boxes that are using downscan converters) to be alot less painful than people usually make it sound.

Things stayed that way for several years until I happened to be at a friend's around 1962. They had just bought a brand new TV that put up an image that looked pretty much as they do today and I thought - "Gee (we said Gee back then) - that looks as good as a movie! These color TV's might be pretty nifty (another word we used back then...)"

Early Gilligan's Island episodes and I Dream of Jeannie episodes were in B&W, as you can verify on Nick at Nite. Yup, it sure was different seeing Jeannie's costume in black & white.

      They do the same thing today with HDTV. They love to show you a bunch of tiny old TVs next to a huge new HD screen so the disparity is as great as possible. Of course, they try to show you the "quality" of the new system. I'm not quite sure how I'm supposed to judge a higher-resolution screen as viewed through my low-resolution screen. Yet sometimes they show a HD screen by itself and say "look at the quality!" as if they think it's somehow going to show through to me. I think it's pretty funny actually.

    In theory, the quality should have been OK, and perhaps it was in a studio, on a high-quality monitor, via closed circuit.

    In practice, the home receivers of the late 1950s and 1960s were lousy. They were very temperamental beasts. They had no built-in degaussers and if you moved them or turned them you'd get color changes due to the earth's magnetic field.

    The tube circuits were unstable and drifted. They had no ability to compensate for any signal variation, so colors shifted from program to commercial, from program to station break, from program to program, and sometimes from camera to camera within a program. You were constantly leaping up to fiddle with the contrast, brightness, saturation, and hue adjustments.

    The tubes were never properly converged (and had about seventeen tweaks needed to converge them).

    The picture tubes were circular rather than rectangular and cut off significant parts of the picture. The phosphors couldn't deliver much brightness, so they couldn't put the usual neutral tint in the CRT face; a set when turned off looked pale grey rather than dark. When turned on, room light washed out the colors (and if you turned the brightness up the picture looked even worse).

    They were trophies and icons of conspicuous consumption, but it wasn't much fun watching them. I've often suspect that at least part of the reason for the popularity of the Disney show is that animated cartoons were relatively unharmed by slight color distortions.

    In the 1970s, solid-state circuits and the introduction of various AGC and other automatic-adjustment features finally brought home receivers to the point where they were worth watching.

Then we went to an 18" dish that gets 150+ channels on two satellites that don't require repositioning, and all look uniformly good (some compression artifacting) especially when compared to two and a half channels in the late 1970s.
