What I find the most fascinating is how many extra features engineers were able to cram into the analog standards. Adding in color signals, closed captions, secondary audio programs and programming data into the same bandwidth while still maintaining compatibility with older television receivers.

[@johngaynor4363]

Old school engineers were wizards. Kind of amazing to see what they pulled off with so little.

An analog signal can transmit a mind boggling exponentially larger amount of data than a digital one. The hard part is encoding, decoding, and dealing with decay/loss. We just very recently figured out how to transmit data with another band of light in fiber optics.

The Japanese were right about choosing a 2:1 ratio. Closer to full widescreen instead of the academy 16:9 compromise that was settled for. However, I really do like the fact that TV and computer displays are all finally using the same resolutions. Very convenient.

[@jeremyandrews3292]

The first Plasma TV I ever got apparently had a physical resolution of 1024x768, but it used rectangular pixels and gave the illusion of being a 720p display until you hooked up a computer to the VGA input. I looked at the physical pixels and checked, but it turned out the resolution it was feeding to the computer was absolutely right, the pixels were just physically rectangular and stretched a 4:3 ratio out to 16:9. The reason this worked at the time was because DVDs usually achieved widescreen by being anamorphic... that is, they actually delivered a "squished" 4:3 picture that, when spread out to 16:9, looked correct. So the TV was designed to accommodate this without a lot of horizontal scaling, by just having the same aspect ratio as the DVD while having a wider screen through the odd-shaped pixels. I will say, out of all the HDTVs I ever watched, I thought that one looked the best with 4:3 content stretched to fill the screen, and I never knew why for years. But once I knew how it worked, it was obvious... because it really is a native 4:3 display, they just managed to make it wider than it is tall. The ultimate test... which worked, was ripping a Blu-Ray and downscaling it to 1024x768, using the anamorphic setting usually intended for DVDs to see if it looked better on this TV. It did... looked better than anything coming in on the HDMI port, or anything from component video. It was kind of weird, because I realized the majority of people using that TV would never see the best picture it could produce, because everything was either too high a resolution and had to be scaled down using a bad scaler, or too low a resolution and had to be scaled up using a bad scaler. But if you feed it an anamorphic widescreen DVD, or better yet a customized 1024x768 signal over the VGA port that reproduces the anamorphic effect? It's perfect. In fact, I now wonder if some of the places that sold those TVs did just that, used a VGA port and a custom signal to show the TV at it's best, using content like that I created for it by hand...

It still hangs in what's now my mothers room. No one ever wants to move this heavy beast. Still have the first Plasma TV staying around. 40" Pioneer 4:3 with 640:480 from around 97.

Really really annoying, so when you look at a native 1920x1080p media on a 1080p screen, most the reason it looks better next to a 720p tv is just because its native and your 720p screen panel is not.

The only thing that kinda pisses me off, that 720p TVs are NEVER actually 1280x720. They are almost always actually 1366x768, simply because it was easier/cheaper for manufacturers to convert existing processes to make TVs, instead of making new ones.

[@ThePreciseClimber]

Yeah, that sucked. The only two ways of getting real 720p back in the day were either finding one of the super-rare, native 720p monitors or using a 720p wall projector with DVI. But there simply were no native 720p TVs. So we were robbed of the true, 1:1 picture clarity on X360 & PS3.

The best reference for this topic from the U.S. perspective is the book "Defining Vision" by Joel Brinkley. It documents the entire agonizing political (and sometimes technical) story behind the seemingly endless battle for high definition television in the U.S. There were around ten proposed resolutions from various organizations at various times for various reasons and the computer industry had little input. The first proposals were analog or hybrid digital/analog systems until one company developed a fully digital system that, while wasn't still good enough, was clearly superior to all of the other proposed systems.

Honestly, pre-digital television broadcasting just feels like a sort of arcane magic to me, the more I know about it, the less sense it seems to make. It feels miraculous that any of it worked. Don't even get me started on CRTs.

[@petrkubena]

Really? To me it seem's very ... primitive for the lack of better word. You can easily understand everything what happens in an analogue broadcast. Digital broadcast is the real magic. You most likely understand it only on a very high abstraction layer. Ie analogue video encoding is something you can explain in a few minutes. Digital video encoding is an art where only handfull of people know how a single frame is encoded from start to finish. You go one layer up and puting I/P/B frames and ordering them is one of the hundreds of problems and there are ten more layers to the digital broadcasting.

The fact that they did not immediately realize the need for square pixels insane. PCs got square pixels already in 1987 with the VGA. Square pixels make things so much simpler.

[@AttilaAsztalos]

I reckon working with a *generated* image instead of a *captured* image might have had something to do with it - it's hard enough figuring out where to put down the next black pixel when drawing a circle with square pixels - if they're not square, it's even worse. Of course, this was immediately subverted by things like the ZX Spectrum video memory structure, where the order was line 0, then 8 lines below, then another 8 lines below - for ONE THIRD of the screen; then continue with line 1, line 9, line 17 etc; then proceed to the second third and repeat. YOU try drawing a circle onto that...

[@devan_danger]

Standard resolution on a CRT TV for basic programming doesn't require the same pin sharp focus of reading fine text on a monitor. Generally any image looks great on a CRT when reading fine text isn't a requirement

Yeah, if you have rectangular pixels, the software designers will often still treat them as if they are square, resulting in a stretched look. Most NES games did have that issue.

Great video. Couple things I wanted to add. SMPTE is general accepted as “simp-tee” for short. Save yourself a mouthful next time. One other cool note is that if you multiply the width by height by framerate from NTSC land(720x480x30) you get the same number as doing the same equation in PAL resolutions. (720x576x25). Both yield 10,368,000. Not sure why this is. Seeing as how both standards have the same bandwidth I’m guessing that’s just the most they could get out of it.

[@eDoc2020]

It's definitely not a coincidence that the line numbers multiplied by the frame rate equals the same number. Or really the same but with the total number of scanlines (525 vs 625). The resulting number is the line rate. It's (nearly) the same because the 625 line standard is based on the 525 line one.

Very interesting! A brief search of online dictionaries only mentions this sense being used in "computing" not other fields. I found a blog I'm sure I can't link, which offers the below: "The word has been used in engineering since the nineteenth century. The word ‘bug’ actually is short for Bugbear. (sometimes found as Bugaboo). It’s meaning is much closer to ‘Gremlin’, where the people who worked on engineering prototypes often grew to suspect that the problems were due to malicious spooks. I sometimes even still hear it said that some software is cursed with malicious spirits. The ‘Bug’ or ‘Bogey’ part of the word is traceable back to the fifteenth century in the meaning of ‘Hobgoblin’, devil or ghost. In East Anglia particularly, the word Bugbear’, first recorded in the sixteenth century, is still used in referring to problems with machinery."

being any ind of early adopter when it came to HD and home theater tech around the turn of the century was insanely expensive and not remotely cost effective. You'd pay huge amounts for the latest tech and then it would be surpassed by something newer long before any kind of reasonable end of life. A $4K HD TV wasn't even all that expensive back then. You could spend more than twice that on a plasma display that didn't even do 720p and which suffered horrendous burn-in if you ever left anything on the screen for a hile - including just station logos and the like.

Input lag is bound to be better on a modern lcd than an HD crt as well (though obv not as good as earlier crt's), and decent minileds will beat the crt for contrast too (as well as most non-Kuro plasmas). Even a modern non-miniled VA panel might beat it for native contrast, though it'll be even more compromised on viewing angles. As much as I dislike lcd's in general, 40+ years of development is starting to pay off.

And why did they decide on the rec.2020 colour gamut if it still can't handle all visible colours, officially it's so they don't require conversion chips to handle imaginary colours but seeing as all digital video requires computer chips anyway that explanation always baffled me.

I actually had 3 screens of this resolution, before the market saw them vanish with 1920x1080 being the only option, at which point I pushed up to 2560x1440. Unfortunately, I wanted to keep my 24" size, but I had to choose between a 1920x1080 24" screen, or a 2560x1440 27" screen, so I went bigger. Also interestingly, I remember a few years earlier when I got my 3rd 1920x1200 screen, that I almost bought a 2560x1600 screen, still 16:10.

The 3008 died in the summer of 2022, at which point only the very first oled monitors had hit the market. They would've been a downgrade height-wise, being a 34" 3440x1440 screen, so I had to "settle" on a 4K 144Hz IPS screen instead.

At 02:05: "Reducing the scanning frequency to 29.970 frames per second, with the remaining bandwith used to carry the color signal" - uhm... no, not at all. I don't know where to start correcting this, as it's so wrong and such a big misconception. In short: the frame rate was reduced to 29.97 Hz in order to reduce interference between the newly introduced color carrier and the existing sound carrier frequency by shifting everything in a manner so that the color carrier and the audio carrier are different by a non-integer multiple of the line frequency. This reduction of the line frequency and this overall framerate (or, rather, field rate) has nothing, really *nothing* to do to accomodate the "higher bandwith" of a color television signal. In fact, the overall bandwith of the NTSC color signal is not at all higher than that of a black-and-white signal. The spectrum of the color sub-carrier lies well (and completely) inside the spectrum of the luminance signal. This is actually why we have things like cross-color artifacts and dotcrawl, and why S-Video (separate Y/C signals) was even invented. Sorry for the elaborate correction, but I just couldn't let this stand as such. Otherwise, as always, great video! Keep it up!

As an additional step, that super-odd resolution of 1366x768 that was common on so many laptop panels for so long was actually a stopgap resolution, that was meant to be compatible with programs that required 1024x768 while also delivering a widescreen resolution for watching 1280x720 media and navigating websites meant for widescreen displays.

[@rager1969]

Back in 2008, a buddy of mine that worked in TV post-production was telling me about film transfers being done in 4K, which was twice the horizontal and twice the vertical resolution on 1080i and being progressive scan (he may have mentioned the fps, but I don't recall). I asked him why it was referring to the horizontal rather than the vertical resolution and he said because film aspect ratios vary so it's better to think in terms of the commonality - the horizontal. I also asked why it isn't 4096, to be true 4K and he said to keep the resolution an integer multiple of 720p and 1080i for easy down converting.

The height of the picture depends on how many perforations high the camera exposed and on ow much of that the director blocked off.

They didn't really change; they just adopted the movie resolution names and used them for the closest video resolution. A "real" 4k frame is 4 thousand pixels wide, not those 3840 computers and TVs use. Move resolutions have always been about the width. The width of a film strip is constant, but how you subdivide the infinite length of the strip is up to you. Although it makes very much sense to use multiples of the perforation and mask off areas at the top and bottom you don't need. Quite the opposite of the fixed number of lines and fuzzy horizontal resolution of TV/video signals. So when digitizing film, the only thing standardised is the horizontal resolution. The number of lines is how many you get after cutting off the black areas and can be different from movie to movie. A notable exception is IMAX, where they run a 70mm-wide film strip horizontally, so it becomes 70mm high and the width becomes the variable.

In France, the movie director Abel Gance invented super wide format called Polyvision in 1927. It was basically 3 pictures side by side of a 4:3 aspect ratio each. But it needed 3 movie projectors. This was not easy to use everywhere. Seeing this, the astronomer Pr. Henri Chrétien tought about a way to do wide screen with a single projector, compressing the image by anamorphosis. He called his system Hypergonar. Those breakthoughs were ingored until 30 years later people in the USA started to watch more and more television and don't go to movie theatre anymore. Movie studios wanted more exciting technologies to bring back audience in theatres. Cinerama is a rip off Gance's system, also using 3 projectors; and the Fox studio bought Hypergonar from Chrétien and rebranded it under the name Cinemascope. The Cinemascope was a sucess. This is why you have wide screen now. And who invented 4:3 in first place? It was William Dickson who wanted a 1,5:1 aspect ratio, but due to technical limitations of technology and dimentions of the 35 mm film gauge decided to make the best out of this and went for 4:3 instead.

High Definition consist of various resolutions. You have to remember when the standard was created, high resolution fixed pixel displays weren't in use. CRT ruled the day, and could display numerous input signals at their native resolution. So the focus was on the source resolution, not the display resolution. When it came to displays, it got even more complicated. A display for sale in the US could legally be listed as High Definition with a native resolution as low a 1024x768 if the pixels were rectangular in shape. For source material it started at 1280x720 progressive. Young people seem to have forgotten ATSC HD broadcasts were limited to 1080i for nearly 20 years. Up until recently, no 1080p OTA broadcasts existed. compression codecs and bitrate play just as big a role in the quality of a high definition image as the output resolution.

Did anything ever even use 1536x864? As far as I know the 4:3 version 1152x864 exists only because on budget CRT monitors you could get 75Hz at that resolution, being between 1024x768@85Hz and 1280x960@60Hz

[@ebridgewater]

​@@Pasi123 I am not familiar with the resolution. iPhone maybe? Though the chart is labelled "Desktop screen resolutions", so I am unsure.

[@Redhotsmasher]

And now that I think about it, what even happened to 1440p? Surely there were more 1440p screens than fucking 1366x768 screens in 2023?

[@jhgvvetyjj6589]

1536×864 is due to incorrectly measuring resolutions. 1920×1080 with 120dpi (125%) is a common configuration, but browsers divide the width and height by 1.25 and report it as 1536×864 so that scalable content adapts to that size.

I suspect the answer is gematria and the moon. Screens are 1080 and 2160p because those are the average radius and diameter of the moon at its equator, respectively. Hence, 1080 and 2160p. 2160 is the sum of a cube's angles, 90x4=360 per face x 6 faces = 2160. Drop the zero, you have 216, the 6th cube number. 6x6x6=216. The most prominent aspect ratio is 16:9. This can be explained with (pythagorean / digital root) gematria. The word "you" = 25 + 15 + 21, as y is the 25th letter, o the 15th, and u the 21st. The sum being 41, the 13th prime, where 13 is the 6th prime and also 6+1+6, a "number of the beast" and also part of Earth's orbital velocity. Which is 66,616 miles/hour. 6 is the first perfect number, the 3rd triangular number, and so on. In pythagorean gematria (compared to "ordinal") a digital root is taken before adding the numbers together. So Y=25, 2+5=7, Y=7. O=15=1+5=6, U=21=2+1=3. Simple digit sum. So You=7+6+3=16. There's the 16 in 16:9. i is the 9th letter. There's the 9. So the screen aspect ratio 16:9 is the ratio of you:i. "Money" is likewise, the word is an encoded reference to the eye of Horus, ie the moon. Mo[o]ney[e]. You also have mon-E, or one e. One energy, one 5, where 5 is the senses, sensory reality, and witht he 5 pointed star it's the top point, the hidden "aetheric" mover, the spirit. The other 4 are the elements, or the visible, the seen. Fire, water, air, earth. The pentagram also encodes the music scale in its unfolded ratios, it has infinite recursion, and so on. Screen sizes and resolutions are references to the moon. Which is chased away by the sun, it reflects the sun, it eclipses the sun periodically. Where the masculine and feminine, the sun, and moon, the beast divided, become one, revealing the corona, ie the white ring. There was an important eclipse over much of Europe in November (11) of 1331. Fold in your ring finger, you have 13. Flip your hand around, 31. 1331. For the older 4:3 screens it's the same. 16 is the 4th square. 9 is the 3rd square. 4x4 and 3x3. ie 16:9. The magic square of the sun is 111 and it's a 6x6 grid. 1080, drop the zeroes, 18. A lucky number. Also 3x6, or 6x3. 6+6+6. Which is the number that connects the sun, the moon, and the Earth. It's the number of "The World". That's the beast. Also in Hebrew gematria the word for "a man" = 216, 6x6x6. It's the number of a man. "six hundred threescore and six" gives 313 and 133, which is a whole 'nother rabbit hole. 1:45 441 lines. 441 is the 21st square. 21x21. 21 is the 6th triangular number. 66 again. Or U is the 21st letter, So U times U. You x you, you alone, or alone with others, in front of the TV. Not that I was ever all that social. 2+1=3. So 33 also. 625 x 576 for PAL. 625 is the 25th square. 25 is the 5th square. 5^4. 576 is the 24th square. 2+4=6. 66. X is also the 24th letter. So XX. 625 x 576 = 360,000. 600th square, 600x600. Or drop the zeroes, 36. The 6th square. 6x6 either way.

Actually, I had long wondered why they chose 720x576 instead of 768x576 for (PAL) DV video (the latter would have resulted in square pixels for 4:3 aspect ratio). Now it makes sense. Thank you.

PAL was a color standard and has nothing to do with the number of lines. The 625 line system existed before anyone even thought of PAL. In the UK the black and white standard was 405 lines though they adopted the 625 line system in anticipation of the color in the 60s.

Doesn't make sense to call QHD 2K as it is 2560 wide (far from ~ 2000). If 2160p is 4K (3840 wide) , then 1080p is 2K (1920 wide).

@@stalefurset9444 it's because 1440p is 4x the resolution of HD at 720p. The 2k comes from the 2560 horizontal pixels while UHD/4k has 3840.

2:00 The scan rate of NTSC colour was reduced slightly to make it circuits easier to build with the hardware of the time; it did not change the bandwidth. The bandwidth needed for colour information was taken out of the bandwidth available for horizontal resolution, leaving colour systems with a maximum resolution of about 160 lines across. (Sort of. The interactions between colour information and luminance information are rather more complex than that, so the resolution actually depends on what colours are being displayed, but if you wanted to display alternating black and white vertical lines on a colour display, you can't do more than about 160 before the TV decides that it should be display colour information.) 7:00 Higher vertical resolutions were introduced long before VGA; even IBM had introduced 350-line EGA by 1984. But it was the Japanese who kicked this off with microcomputers (probably due to wanting to be able to display kanji reasonably well) few years earlier (around 1981) with 400 line displays in systems such as the NEC PC-8801 and Fujitsu FM-77. (And of course the Japanese were heavily involved in later HD standards, since they both used almost exactly the same NTSC system as North America and had a very strong industry building TVs and exporting them worldwide.) BTW, in North America we usually pronounce "SMPTE" not letter-by-letter, but as "simptee."

Yes. 720p (1280x720) is part of the HD standard. Many people confuse this with the 720x480 resolution of DVDs. It's an unfortunate coincidence that 720 features in both specs.

It is HD but came later. 720p was born out of NBC & Zenith's 787.5/60p experiments which began in the early 1980's. NBC/Zenith claimed that a progressive scan image would be better & simpler than an interlaced (then 1035i) image and experimentally obtained that 787.5 would be the best mix of static resolution, motion resolution, and bandwidth; however, there was little hardware available unlike what the Japanese had. Regardless, NBC ended up using the 787.5 system to fight against 1035i being accepted as the sole American standard in the early 80's. This standard was later revived when digital HD transmission was considered in the USA & modified to 750/60p (720p) since it could use the same pixel clock (74.25MHz) as 1080i.

René Barthélémy invented HD in 1941, which later became analog HD standard in France in 1948 known as « 819 lignes ». It was black and white, used 12 MHz bandwidth and Acamedy aspect ratio. It was adpoted by neighbourgh French speaking countries. The last one to use this system was Monaco who discontinued this system in 1985.
