SECAM is definitely an interesting color standard, it was also used in Czechoslovakia, but instead of having SECAM VTRs etc. it was all done in PAL, mostly on Ampex and Sony stuff (Czechoslovak national TV had Ampex VR2000 since the 60s with it's logo scratched off) and then converted to SECAM before transmission. So in early 90s all they had to do was to bypass the SECAM converters and we became PAL region.

An important benefit of SECAM was its insensitivity to timebase errors (that are produced in VTRs). That meant that the old monochrome TBCs could continue to be used. The time and phase insensitivity also allowed distribution over old and vast networks (think USSR) without degradation. Its biggest drawback was that it could not be used in post-production. It's impossible to mix or key a SECAM signal, you need either the component original signal (pre encoding to SECAM), or you must decode and then re-encode, causing degradation.

I was at the WM in football in 1998 in france making television for the national broadcaster here in Denmark (still working there) and was on almost on all stadiums with our OB truck. Many of the french OB trucks was PAL composite system, with a PAL to SECAM encoder. I remember that on Bang & Olufsen television set there was a remote command that sometimes was activated, that shifted the IF signal from negative to positive. So now the PAL signal looked like the SECAM signal. Now its a lot easier, no analog transmision. Mostly digital with component HD or UHD signal. All the Phillips equipment you have in the video, are developed here in Denmark. When Phillips sold that division out, it became PTV, and later DK Technologies. Great video by the way.

A lot of production in these countries shifted to PAL and was then transcoded to SECAM for tx. Second, SECAM was adopted by France and Russia as they used long distance high power stations which gained from the improved colour fidelity.

I lived on the south coast in my teens. French television could be received regularly with an aerial swing to the South East and some modifications of a dual standard TV. Set to 405 lines on VHF, one could tune in to some 819 lines transmissions, albeit with two narrow pictures displayed when synchronised. No sound of course. BRT, Belgium also used positive modulation and AM sound using System C on VHF, so could also be received from modifying the tv set's internal slider to enable 625 lines on VHF, again with no sound; the carrier at +5.5 Mhz, whereas the 405 system was -3.5 Mhz below (simplisticly). Any engineers having experience with turret tuners will know! Turning to UHF and disabling the set's internal slider switch to enable AM sound and positive modulation, one could pick up the two other French System L 625 line channels, Antenne 2 and FR3. Again, no sound for previous reasons. The disadvantage with positive modulation, particularly at VHF, were ignition noise and industrial noise spikes came out as picture white spots, the greater the interference, the greater the white spots! Considerably more noticeable than black spots under negative modulation systems.

Supplemental. In UK dual standard sets, switching from VHF to UHF also switched from System B to System I: Both line standards and modulation standards *together*. The internal switch looked like a long strip similar to a slide rule operated by a cable. One just unhooked the cable for each of the circuits; 1. modulation in the IF strip and, 2. timebase circuit for line frequency. The high voltages in these sets meant you had to know what you were doing and take safety precautions. #Caveat.

Of course, unless engaged in 'border blasting', broadcasters tend to want to avoid signal bleedthrough into neighbouring countries, or at least that's the impression I get... Still though, I've always thought it a pity, thinking about it from the standpoint of an average viewer 'in the wild', rather than from the engineering p.o.v., that British TV's couldn't ordinarily decode French signals (or vice versa). It would have been nice for British and French householders to have been able to watch each other's programmes, with only the need for the right sort of aerial pointed in the right direction, and no need for the complicated and fussy (but clever) workarounds you describe. This, of course, is exactly what Irish television viewers who lived near the East coast or the Northern Irish border did. I don't know about viewers in places like Cumbria or Anglesea, or the Isle of Man, but I know many people in Northern Ireland 'returned the favour' -- but only in certain neighbourhoods, since, bizarrely, increasing your choice of TV stations by 50% more or less for free would be seen as a political statement! (The need for an outside aerial mounted high, and pointing in the right direction obviously meant that 'discretion' wasn't an option! Of course, going back to the subject of picking up French TV in England, even leaving aside their incompatible - in - practice SECAM system, one would also be faced with the insurmountable difficulty that French broadcasters stubbornly insist, to this day, on using the French language (probably with an eye to selling programmes to Canada, or something?! 😉 ) I've always been intrigued as well, by France's having an 819(? I can't refer back!) - line system, so long before everyone else, at a time when, as you mention, many British viewers were still getting by with less than half that resolution! I seem to recall Japan having something similar? (TV, you may have gathered, is not my field!) I could just be confabulating, but I seem to have this recollection that the French High - Res (for the time, anyway) system was in Black & White only(?) -- Interesting trade - off, if true...

@@richiehoyt8487 The French 819 line system had 737 active lines, and was interlaced. (Compare with current 720P!) Indeed, like the UK's 405 line system it was black and white only and the aspect ratio was 4:3. The (VHF only) channels too, were interlaced over Band I and III with a bandwidth of 14MHz. Compare that with the 405 line bandwidth of a mere 5 MHz. Still with air pressure being high, reception was fairly regular at least at VHF in Hastings. Due to licensing, countries did and do minimise overspill. Different line standards and colour systems often meant production and market protection, so set makers in France at a distinct advantage to make 819 line sets. TF-1 eventually ended up on UHF with the rest. I now live in North Wales and occasionally recieve TV from Ireland. The signal makes it's way across the Irish Sea and by complete coincidence, channelled through the Menai Straits to this location. Digital TV in Ireland uses DVB rather than DVB-T2 on the multiplexes. These days of course, with the advent of satellite TV, Distance reception (DX-TV) much easier with a moveable dish and asatellite finder, but that's another story!

If you decide to look up that video, there's some weird music video starting at around 11:30 where this whole "color popping in and out" thing seems especially bad

Even more weird than system L was the system E used on VHF (819 lines). There the position of the AM sound carrrier (vs the positively modulated AM vision carrier) was alternating between adjacent channels. So, on two adjacent channels the video carriers OR the audio carriers would be next to eachother. It probably prevented interference from vision into audio, but of course that must have been a nightmare for TV set builders, they would have to either have two different IF strips (with mirrored filters) or have to different ranges of local oscillator in the tuner and using upper/lower mixing. AM sound was problematic in itself. One could not use intercarrier sound (i.e. getting the sound from the video demodulator) as it would suffer from extreme interference from the sync. So, a TV set with AM sound required an AM demodulator at the IF, not at 5.5/6.5 MHz. And the TV set had to be tuned accurately enough for that AM signal (with a bandwidth of 20 kHz or so) to be within the AM filter of the receiver. A set with FM intercarrier sound could be way more off tuned because the frequency difference is only dependent on the transmitter frequencies, not on the receiver tuning. So sound was always OK and tuning would only affect the picture.

I presume that SECAM television sets were originally more expensive to manufacture than PAL sets. Certainly the market penetration of colour TVs in France was way behind that of the UK during the 60s and 70s.

Great video. Another possible explanation for System L using positive modulation that isn't a political one is a technical one. 819 lines was also positively modulated, as was the old British 405 line system. British dual-standard sets were very complicated and not all that reliable, having to support 405 positive modulation, 625 negative modulation, as well as both AM and FM audio. Retaining positive modulation with AM audio on System L could simplify dual-standard 819/625 line sets and reduce costs too.

I remember living in the southernmost part of Sweden in the 80s before satellite TV. During nice weather in the summer we could receive both West German (PAL) and East German (SECAM) TV. I got a dual standard Philips TV and I was surprised to find that I needed an almost noise-free reception of the East German TV station before I could get color and then it was either full color or no color when the signal got weaker. The West German stations on the other hand showed color as soon as the sync signal locked even though the picture could be very noisy. No wonder most eastern European countries switched to PAL in the 90's. Today I wouldn't bother watching German TV since everything is dubbed...

But the television standards of PAL West and SECAM East were black and white compatible. The same FM tone and frequency grid was used. For black and white broadcasts, SECAM switched off the color carrier, PAL did not. After 1990 the Ost broadcasting stations were quickly converted to PAL.

This was probably some kind of protection or threshold in the circuitry of the set. SECAM has some advantages over PAL and one is performance with low signal and poor reception. The typical effect associated with SECAM and low/noisy signal was the "color explosion" - the colors become oversaturated instead of faded. This was quite obvious with the old Russian sets from my childhood where there was a knob on the back of the set to turn off color which was quite useful when there was bad reception to remove the bursts of oversaturated color. Maybe your Philips was smart enough to do it automatically.

Sovok (the USSR) chose SECAM over the NTSC just because the latter one is very susceptible to phase distortions yet unusable in the Soviet transmission lines as the relay TV network there was of very crappy quality.

Really interesting Matt, thanks for sharing. It's fascinating to hear about these exotic means of encoding and broadcasting TV

My first digital capable TV, a 28" 16:9 Hitachi had undocumented analogue capabilities which I discovered using my first analogue and digital satellite receiver. The satellite receiver could send 625/ PAL to the TV whatever satellite signal was being received but could be set to send in NTSC and SECAM as well and the Hitachi TV would accept them. When a NTSC 525line satellite signal was fed to the TV as 625/PAL motion was jerky which cleared when switched to 525/NTSC and a TINT option became available in the TV's settings menu. When the French analogue satellite 625/SECAM signals were seen, text had noticeable colour ringing which I think must be the origin of the STREAKAM nickname for the system.

Another plus of SECAM is that it could be recorded on monochrome VTRs and play back color without the need for time base correction. Even industrial and consumer VTRs for NTSC and PAL must have at least hetrodyne systems to stabilize the chroma signal. The NTSC and PAL broadcast machines started with analog voltage variable delay lines, then went to digital storage when technically available. SECAM VTRs never needed this additional circuitry for color. The problem for NTSC and PAL VTRs was once again, phase errors. I don't care how good your machine shop is, nobody can manufacture a tape transport stable enough to avoid destructive phase errors in an analog color video signal.

The color tint in those control fields just shows little phase error of the R-Y and B-Y demodulator. Those errors are compensated on other parts of picture by PAL switching, so you just loose saturation a little, but in those fields became visible even if the difference is just few degrees. So by those fields you can adjust PAL demodulator just by eye. And they were not only on Telefunken test picture, but were added to Philips one too.

Not sure if others have posted - but I suspect System L using +ve modulation and AM sound is because the previous French 819 line (System E) system was also +ve modulated and also used AM sound? Would it have slightly simplified dual-standard receiver design - or just been 'what we do'? (The UK also used +ve modulation and AM audio for its 405/50 B&W system - System-A). Weren't the Bell/Cloche filters also related to the compatibility issue? B&W broadcasts in PAL/NTSC have no subcarrier added to the luminance - so deliver a perfectly acceptable B&W picture to a B&W TV (as there are no subcarrier dots or cross-luma). SECAM broadcasts of monochrome B&W content still have subcarrier present added to the luminance, meaning B&W broadcasts were impaired on B&W TVs with no subcarrier filtering (as there was still subcarrier overlaid and this would be seen as dot crawl on monochrome TVs). As a result I think the bell filters are partially there to reduce the amplitude of the FM chroma subcarrier as the subcarrier frequency nears the FM zero points - i.e. where Dr and Db are near zero when the content is in B&W?

BBC and ITV wanted to implement a compatible NTSC-A service in the late 50's but the Government insisted they wait for a German system as the UK was trying to overcome French objections to the UK joining the Common Market. Would have saved a lot of money on transmitters work @@Alozhatos

Interesting. Thanks

Bonjour, baguette, foie-gras, sécam, et cocorico.

A distortion of SECAM was the "red teeth" effect. Especially evident with women presenters wearing bright lipstick. I am uncertain of the precise reason, but it was evidently due to delayed chrominance. I am not aware that PAL suffered from this effect.

Very interesting what you write. Let me tell you that in 2012 I bought a 32" HDTV Sony, thinking that brand has a good prestige. But I noticed sake effect you describe, ears of a man on screen like bload, sometimes bloady hands, lips borders as painted makeup, etcetera. Me as graphic designer said to my self _no no no no._ So I changed the purchase of Sony and LG 32", wich is perfect colors in all situations of image. White areas are not exagerated luminousity fir example, and color problems are inexistent. Curiously Samsung black areas (such as shadows, hair) sometimes looks like a ultra dark rare image. Greetings from Santiago de Chile.

9:48 TV bought from Saudi Arabia doesn’t have SECAM-L. Only NTSC-M, PAL-BG, PAL-I, PAL-DK, SECAM-BG, SECAM-DK only. + AUTO, PAL, SECAM, NTSC 4.43, NTSC video outputs.

It would have made much more sense to use a delay line and transmit one color at a time but with VSB-SC modulation. Like the FM stereo subcarrier but only keeping the lower side band. Phase errors would lead to a decrease in saturation but no color shift.

First Secam versions were in fact like NTSC using AM-SC with only one color difference signal transmitted in each line. But then they started to solve other problems like early VTRs errors and long distance line phase errors and they switched to FM. Secam became too complicated and the quality was compromised.

Supreme Effort to Counter American Methods

@richjames2540

More likely at the time was to counter Allemand (German) Methods. There was contempt in France for the endless delays from Telefunken and their NTSC with a swing burst system... Memories of German behavior in the second world war were still strong.

Hey you got a nice set!! I endet up making a mustistandard Philips PM5534 for PAL and Sécam...It works well but when it comes to the modulator i am stuck `cause of the vestigial side band filter. Where did you get the PM5680MS. That would be a lot simpler for me than having seperate modulators for each system!!! I need a rack for all of them. System: C L L` G,B D,K I M,N B.t.w i like your videos!! A1!!!

Actually France wanted to save their industrie same with cars. In the 70`s when Japanese cars were a threatso they only allowed a certain number cars being imported. But then the Japanese outsmarted France Japanese carmakers assembled their cars in other countries than Japan to "bypass" that regulation. But maybe there was also "pride" involved.

Dont forget there is this weard antenna plug called: Pal plug and Sécam plug.🤣🤣🤣🤣 What does a color system have to do with a plug and the already existing b/w sytem is way beyond me because the socalled "PAL" plug is in reality called IEC plug!! How often do Americans say Pal has 625 lines and NTSC has 525 lines.😡😡 Hey dont forget system N !! Pal 625 lines and sound carrier 4.5Mhz so its the same narrow bandwith like system M in USA. Yes there is a PAL M and a PAL N used in south America So just for "fun" i "created" fantom systems like system "L" positive modulation but with FM sound and NTSC 4.43Mhz color. Now whats that???????🤔🤔

Indeed a major irritant is the assumption PAL is 625 lines and NTSC is 525 lines. Number of lines has nothing to do with the colour encoding method.

You are VERY right at 9:45 "so lets keep these pesty German tellies...." I am not a TV and not a TV system BUT i have/had the same problem because i am a Swede of partly French and German background. The Germans didnt like my French part and in France it was just the opposite. And the biggest joke is that them 2 countries are fromer members of the EU!!! Well i am sad the UK left the EU but i understand the UK because Germany is ,dont get me wrong anyone,the "leader" in Europe especially when it comes to sytems and technologies...like the bulky non polarised mains/power plug ,the "SCHUKO" plug that is now used in almost in every country except UK,Ireland,France, Switzerland. Yeah a SCHUKO plug that is not polarized!!!
