Under USE it states "In many European Union countries, S-Video is less common because of the dominance of SCART" This is factually incorrect, almost all SVHS machines were supplied equipped with S-Video sockets in addition to SCART. In fact I have never seen an SVHS machine without s-video socket. — Preceding unsigned comment added by 145.224.144.45 (talk) 10:12, 26 February 2015 (UTC)
"no console ever came with an RGB SCART cable packed in (it had to be purchased separately) generally coming with RF adapters at first"
French guy here - my consoles definitely nearly always came with a SCART cable as the default in the box (I bought an Atari 7600, Sega SC3000, Nintendo NES, Sega Master System, Sega Mega Drive, Sega Saturn, and Sega Dreamcast; all of those came with a SCART cables outputting true RGB (sidenote, the NES is an odd one, but that's another story)). Exceptions I bought were the PS1 (composite, w/ scart "adapter" (composite over the comp scart pin)), N64 (composite, don't remember if there was an adapter) and Xbox (composite cable w/ scart "adapter"). I still have these pieces of hardware at home. — Preceding unsigned comment added by 109.190.114.197 (talk) 17:07, 7 July 2015 (UTC)

I made a bet with my friend - in S-video the S stands for Super video, or Serial video??
S-Video certainly does stand for "separated video". Y/C is not a "serial" or packet transmission protocol. The erroneous term "super video" came from S-Video's early association with "Super VHS" (S-VHS), though S-Video and S-VHS really have nothing to do with each other. --Mark Rizo 07:08, 22 April 2007 (UTC)
Question?
Does anybody know what Y/C stands for in terms of SVHS? I was asked the question in an interview for a job at a Film and Video Archive today. I thought it was a trick question. Any ideas?
Can it be possible to have an S Video output from the laptop and send the signal to Coaxial Cable input port of a TV. Can it help solve the proble of B&W signals being recieved on TV from the laptop in case of normal S Video connection that is done?
Saad
Long Explantion: Co-ax is composite (or combined) video whereas S-Video is separated video (loosely referred to as component video by some - though not true component video like RGB connections). S-Video is a 4-wire connection with Luminance and Chrominance on 2 separate wires. Composite (standard coax) is single conductor carrying both luminance and chrominance.
But you can mix the svideo signals with a small capacitor to get a composite output http://www.epanorama.net/circuits/svideo2cvideo.html

I am looking to buy a DVD player (Philips DVP642), and while I don't have component on my TV I do have an S-video in. I've been playing things via my video card which has an S-video output as well. Will playing a DVD be as simple as swapping the cable from the computer to the DVD player? Can I hot swap it, or will that be a problem?
Thanks, JoeSmack [[User talk:JoeSmack|(talk)]] 19:45, 9 December 2005 (UTC)
1) Can you provide an pinout of the s-video cable pins? Every article on cable standards should be required to have a pinout. 2) Who developed the s-video standard? Thanks. 3. Is there any audio going through a S-Video connection? Or is it only video. Thanks
I have a s-video cable a TV s-video compatible and a laptop which has a S-Video port. I tried connecting the laptop to the TV using the svideo cable, but it doesnt seem to work! Am I missing out on something?

I want to play 4:3 video off a widescreen laptop through the S-Video output. What will the output dimension of the video be?
The aspect ratio (such as standard 4:3 and wide-screen 16:9) of the video played is not changed merely by playing the video on a screen with a different aspect ratio. If you play a video that has a 4:3 aspect ratio on a TV that has a 4:3 aspect ratio you will get a video in 4:3 aspect ratio that fills the same space as the original video. However, some edges of the original video may not be completely visible on the TV due to the way the TV may display the original video.
If you play a video that was recorded on a 4:3 aspect ratio (such as with non-widescreen camcorders) on a wide-screen (16:9 aspect ratio) TV, LCD or HDTV the video will play in a "pillar-box"; that is, there will be two vertical bars on the edges of the video. The video may also look a little stretched on the vertical axis (top/down) giving people a slight cone-head appearance. This can usually be compensated if the TV has manual adjustments for the aspect ratio. If it does, then the video will play on a "window-box" - that is, there will be two vertical and two horizontal boxes around the video.
If you play a wide-screen (16:9 aspect ratio) video on a 4:3 aspect ratio TV the people will look stretched on the horizontal axis; basically, they will look fatter than they would normally appear; circles will be stretched on the horizontal plane and will look like ovals. This may also be able to be somewhat compensated by the changing the settings on the TV or projector, though not all TVs or projectors allow you to compensate for the aspect ratio of the incoming signal. — Preceding unsigned comment added by Svideo (talk • contribs) 06:49, 7 February 2011 (UTC)

Oppose — an A/V connector type used in a video transmission protocol, even the one that birthed it, is mixing apples with oranges. While S-video is the normal use of the Hosiden connector, I have also seen it used in other four pin low power applications (e.g. An optomitrists lamp for examining the retina, X-ray security equipment in airports) simply because it is small, compact, and easily obtainable in a variety of PCB edge mounted configurations. FrankB 21:44, 22 May 2006 (UTC)
Perhaps this S-Video article is not the correct article to merge the Hosiden connector with, but I feel there is some confusion among what should belong in each of the DIN_Connector, S-Video, and Hosiden articles. It appears that the content of the Hosiden article speaks specifically about the connector's application to the S-Video protocol, (except for the links section), while it should contain information about the physical connector and it's possible application. I have personally seen this connector type on many devices for a variety of applications, including the Apple_Desktop_Bus, power, and A/V applications--and feel there should be a clear explanation of this, connector vs. protocols commonly carried on the connector. Would it be reasonable to merge the Hosiden article in to the mini-DIN section of the DIN_Connector article? Or should the content of that section be moved to the Hosiden article? It is not clear to me what is the proper name for the connector, personally I have found mini-DIN to be the "correct" and popular name for the connector, though this could be specific to my geographic location in the United States—. Joeyhagedorn (talk) May 29, 2006, 21:23 (UTC)
Support — As it stands, with the exception of the 1st sentence, Hosiden talks only about the connector's application in S-Video. And so, content-wise, these two articles are duplicates.
That said, the physical Hosiden connectors are equivalent to mini-DIN connectors and "Hosiden" is the name of a Japanese manufacturer.
So my take is that the Hosiden article is completely wrong. Instead the content of the Hosiden article (as it is now) should be merged with S-Video (though aside from the graphic I don't see any new information), a Hosiden Connector article should be created and redirected to mini-DIN and Hosiden should be either deleted, or changed to an stub on the company.
How's that for a solution? Mobius 02:18, 31 May 2006 (UTC)
Can we have some description about the 7-pin s-Video?
There are many different configurations of a 7-pin connector that can fit in a circular "mini-DIN" connector. On laptops, and on many graphic cards on desktop computers, the most common configuration of the 7-pins is three pins on top, 4-pins in the middle and a rectangular "key" on the bottom, as illustrated at http://www.s-video.org/7svto3rca.html
There is some information on the net that states that the 7 pin s-video connector is not a 'standard' mini DIN connector; however, there is an "accepted" 7-pin mini-DIN connector and many other different configurations, among them the most common configuration mentioned above. The 7-pin S-Video output connector on laptops provides many different ways of sending the S-Video signal and/or the composite video signal and/or the digital audio signal. The actual signal or signals that may be output through the 7-pin mini-DIN connector will depend on the what the graphics card supports; some just support S-video, others S-Video and Composite Video, others just composite video and others all three, S-Video, composite video and digital audio.
The 7-pin is deliberately designed to accept the standard 4 mini pin DIN connector as commonly used for S-Video connections; however, since there is some slight variation in the manufacture of a 4-pin S-Video connector, the pins may not line-up exactly to match the 7-pin connectors, resulting in bent and broken pins. In addition, there are many 4-pin S-Video connectors that have a rectangular "key" that will not properly fit the 7-pin connector, thus resulting in broken keys and thus a flimsy connection. The ideal connection is to use a 7-pin to 4-pin adapter, as illustrated at http://www.s-video.org/7p1.html The advantage of using this adapter is that the outer mold of the adapter that mates to a laptop's 7-pin socket is just wide enough to fit into the 7-pin socket. Another advantage of using a 7 to 4-pin adapter is that is serves as a "port-saver."
In addition composite (CVBS) video is available from one of the other 3 pins and can be accessed by a suitable mating connector. The key in the 7 pin socket is designed to accept both 4 and 7 pin plugs. However, the key in the 7 pin plug is designed to prevent the plug from being inserted in a 4 pin socket (though as ever, extreme force will override the key) and will also result in breaking some of the pins. The presence of a 7 pin socket on a graphic card (or laptop) does not guarantee that CVBS video is, in fact, available. 86.176.155.137 (talk) 14:17, 14 January 2011 (UTC). However, there are adapters that take the 7-pin S-Video connector and convert the signal to Composite Video on an RCA connector, usually color-coded yellow. Such adapters are illustrated at http://www.s-video.org/7pin2rca1.html
What about the max/recommended length of cable to carry a S-video ? Jeff schiller 00:00, 21 November 2006 (UTC)
http://www.google.com/search?q=s+video+max+length —Preceding unsigned comment added by 155.138.3.21 (talk) 20:22, 24 September 2007 (UTC)
There are a lot of issues that can develop when running long lengths of cable. A safe length for S-Video is 150ft. This length is subject to signal strength from the source unit and being run in an area that is relatively free from interference.
If you need to increase this length, you can use a device called an S-Video Balun. The S-Video Balun is a stand alone device that transforms a single S-Video channel to and from CAT-5 twisted pair cabling. CAT-5 cable is much cheaper than S-Video and can be run up to a maximum of 500 ft. —Preceding unsigned comment added by 217.139.109.100 (talk) 12:58, 11 June 2008 (UTC)
There have been questions about laptops but I have a S-Video output on my PC and an input on my TV so I tried connecting them but it doesn't work. What do I need to do to make it work?
Never mind about that. I got it to work but it's not in color. What should I do to fix it?
Aspects of this question deserve to be clearly delineated in the article (in a way that non-tech readers are likely to understand). The basic S-Video cable carries two signals. If only one is working, for whatever reason, you may see a monochrome image. Apparently, some people sometimes use this odd possibility on purpose, when they WANT to convert an image to black-and-white greyscale. *** Beyond that basic matter, there is 4-pin vs. 7-pin S-Video. It is apparently usually OK to plug a 4-pin male into a 7-pin female, but not vice-versa. However, it seems that many laptops have "proprietary" non-standard S-Video-ish sockets, that may look completely normal -- but produce unpredictable results. So, only studying the tech specs for the laptop will answer. -69.87.199.161 (talk) 10:52, 24 June 2008 (UTC)

Who made s-video and when did it become a standard? 24.111.216.12 04:24, 3 March 2007 (UTC) 10:21 pm 3-2-07.
The following comment is wrong:
"S-video has always existed. S-video signals must exist before the signals are combined to transmit composite video. So the answer must be whowever developed the original NTSC colour system. 81.157.216.80 17:23, 19 October 2007 (UTC)"
S-video as a connector came out in 1987-88 when JVC S-VHS machines were launched as it became apparent that the composite video signal was inadequate in resolution to allow the full 420 lines of S-VHS to be transferred from one machine to another. --Quatermass (talk) 10:04, 11 October 2010 (UTC) Note, the preceding comment is also wrong. It is not correct to state that "the composite video signal was inadequate in resolution." In fact, composite video and S-Video have the same resolution, the difference is that in S-Video, the brightness and color signals are delivered separately to a TV that supports S-Video. When the brightness and color information is delivered separately, the TV does not have to separate the composite (combined brightness and color signals) and thus it reduces a processing step that the TV has to do when it has to separate the brightness and color signals from "composite" signal. When the TV separates the brightness and color signals on the composite video signal, there are some video artifacts that may be visible on the TV screen. Those video artifacts may be in the form of a little dots that appear to be crawling on the edges of contrasting colors and are commonly known as "dot-crawl". Dot-crawl was really not a big deal for about 40 years - most baby-boomers grew up with your regular standard definition "square" TV and probably never noticed the dot-crawl. The main reason that they never noticed the dot-crawl is that our eyes are part of the "resolution equation" and the dot-crawl is really not visible when the TV is seen at about the distance that it was meant to be seen, at a 4-to-1 ratio, the one (1) being about the horizontal size of the screen and the four (4) about four times the horizontal size. At that distance, most people will not notice the dot-crawl, and if they did notice it, our brain can quickly adjust to the dot-crawl and thus basically ignore it. The advantage of S-video is that the TV that supports S-Video will not have the "dot-crawl" video artifacts and thus the TV will look "sharper" and "brighter" than comparing it with just a composite video signal.
The S-Video connector was developed by Mogami and JVC for the JVC video equipment that began to support S-Video.
The second paragraph in the introduction starts: "S-Video is only one of several types of Y/C video connectors, but it is, by far, the most common." This implies that S-Video is a connector, which is false. S-Video is a video format. The most common type of connector that is being referred to is a 4-pin mini-DIN connector. I will change the text to reflect this. Snottywong 12:56, 7 April 2007 (UTC)
I beg to differ: S-Video is only one type of connector for Y/C signal transmission, though it is certainly the most popular. It would be more appropriate if the article was titled "Y/C" or "component Y/C". I have used Y/C for nearly 20 years, and I assure you there is no electrical signal difference between Y/C via S-Video and Y/C via dual BNC, dual RCA, 7-pin "dub", or any other Y/C variant. S-Video is just one type of connector for Y/C signals, just as composite video signals are transmitted via different connectors, e.g. BNC, RCA, 1/4 inch patch cables, etc. --Mark Rizo 06:55, 22 April 2007 (UTC)

The pinout diagrams for the 9-pin connector are confusing because there are no numbers shown next to the pins. Are better diagrams available? Also, does ATI use the first or second example? The text is confusing because it talks about the first example twice and doesn't refer to the second. I now see there is mention of this issue under the "nVidia 9-pin" topic below. Thanks Stuart H.

The article says "carries high-bandwidth 480i or 576i resolution video, i.e. standard definition video" but the S-Video signal only contains 120 lines (as it said in the article "For NTSC S-video's color resolution is typically 120 lines"). What's right? Can it be explained more clearly? --I hate to register 12:12, 6 August 2007 (UTC)
The 120 lines is referring to the the Chroma or colour aspect of the S-video signal which is much lower in resolution that the Luminance which is 420 lines. --Quatermass (talk) 10:09, 11 October 2010 (UTC)
In the Overview section it says "In composite video, the luminance signal is low-pass filtered to prevent crosstalk between high-frequency luminance information and the color subcarrier" which I believe is factually wrong. In all three broadcast systems (NTSC, PAL, SECAM) the color (burst) signal is multiplexed in time with the luminance signal so that there is no reason the luminance signal cannot use the full bandwidth of the channel. (VCR recording is a totally different issue.) GS3 08:35, 24 August 2007 (UTC)

The 7-pin drawing shows uneven pin hole spacing. The row of 3 holes is evenly spaced, the row of 4 holes is asymmetrical. The 7-pin socket photo matches this, but is left-right reversed. This visual mis-match leads to confusion, although if one is male and one is female it is correct.

The article used to be telling it means 'separate video (erroneously super video)'. The parenthetical remark was removed here, and now an anon changed 'separate' into 'super'.

Well, back when the ONLY product that used an "S-Video" jack was an S-VHS VCR, it (in the JVC S-VHS decks manuals) referred (as well as many products around the late 80's/early 90's) to the jack as a S-VHS jack, not S-video. S-video came into play once S-VHS failed to gain popularity and DVD, videogames and other devices started using the S-VHS jack since it was the best until component. The "S" in S-video stood for super as in SUPER-VHS, originally.

I agree. Back in the late Eighties in the UK all S-video connectors were referred to as S-VHS connectors or Super-video plugs. They were never called Separate-video. Composite video was too poor in quality and RGB too expensive to implement so JVC invented a compromise. --Quatermass (talk) 10:21, 11 October 2010 (UTC)
It shows that the subcarrier for Y shares a portion of the band with C. The frequency band of Y should not interfere with the one for C, as they are separate signals.

There's presumably sync signals in amongst all this, like there is in AFAIK every other video signal format; I had originally been under the impression that S-Video has a dedicated sync line (or lines!) due to the 4 pins+shell, but then seeing the pinout there, it appears the only signal lines are luminance and chrominance. So where's the sync signals? I can see no mention in the article. Mixed with Y? With C? Copies in both? Separated with H in one and V in the other? Something else entirely? 80.175.8.54 (talk) 10:05, 18 May 2009 (UTC)

"The S-Video connector is the most common video-out connector on laptop computers; however, many devices with S-Video outputs also have composite outputs."
If this was ever true, it was in the past. This should be updated as I would say VGA is the most common nowadays, although even that is becoming a little aged.

Please stop. If you continue to blank out or delete portions of page content, templates or other materials from Wikipedia, as you did to S-video, you will be blocked from editing.
The luminance (Y; gray-scale) signal and modulated chrominance (C; color) information are carried on separate, synchronised signal and ground pairs.
In composite video, the luminance signal is low-pass filtered to prevent crosstalk between high-frequency luminance information and the color subcarrier. S-Video maintains the two as separate signals, so that detrimental low-pass filtering is unnecessary. This increases bandwidth for the luminance information, and also subdues the color crosstalk problem. The infamous dot crawl is eliminated. This means that S-Video leaves more information from the original video intact; thus, it offers an improved image reproduction compared to composite video.
Due to the separation of the video into brightness and color components, S-Video is sometimes considered a type of component video signal; however, it is also the poorest, quality-wise, being far surpassed by the more complex component video schemes, such as RGB. What distinguishes S-Video from these better component-video schemes is that S-Video carries the color information as one signal. This means that the color has to be encoded in some way, and as such, NTSC, PAL, and SECAM signals are all decidedly different through S-Video. Thus, for full compatibility, the connected devices not only have to be S-Video compatible, but also compatible in terms of color encoding. In addition, S-Video suffers from reduced color resolution. NTSC S-Video color resolution is typically 120 lines horizontal (approximately 160 pixels edge-to-edge)[citation needed], versus 250 lines horizontal for the Rec. 601-encoded signal of a DVD, or 30 lines horizontal for standard VCRs. One very prominent fact about S-Video, is that the cable can carry a signal longer with out degrading the quality as in other cables, which is why it is still fairly popular today. For example, in theory a 400 foot S-video cable will have a better quality than a 400 foot hdmi cable.
When used for connecting a video source to a video display that supports both 4:3 and 16:9 display formats, the PAL television standard provides for signaling pulses that will automatically switch the display from one format to the other. The S-Video connection transparently supports this operation. The S-Video connection also has general provision for widescreen signaling through a DC offset applied to the chrominance signal; however, this is a more recent development, and is not widely supported.
I have reverted an edit by Special:Contributions/Doniago because it removed information. It is based on an dictionary, it has the sources. Thank you. Hinata talk 10:55, 26 August 2010 (UTC)
The article states that the chroma signal consists of U and V (or equivalently I and Q) in quadrature amplitude modulation, whose carrier frequency in NTSC is 3.579545 MHz. The entire U and V resolution of Rec. 601 would fit in 0.20-6.96 MHz. So I see no fundamental reason why the C signal couldn't carry full res, making it theoretically equal in quality to 480i component. The article has a citation needed tag on the horizontal chroma resolution of S-Video, but according to one of the above talk sections, it's just a lack of inline citations. Does one of the sources define the bandwidth of Y and C in S-Video? Or is it just that devices restrict chroma to 3.0-4.2 MHz so that the composite signal path doesn't need a separate bandpass? --Damian Yerrick (talk | stalk) 16:00, 8 October 2010 (UTC)

about 7 pin connectors - hoaxes do exist.. and 7pin din connectors do exist .. but it does seem not unreasonable to ask for proof that 7 pin din connectors have actually been used for S-video. It's not as trivial as it may seem to some - I have no idea what connectors have been used other than the standard connector. Old manuals and pinouts should be available online somewhere, I've got to repeat that the majority of this article is non-obvious to an average reader.Sf5xeplus (talk) 03:37, 18 January 2011 (UTC)
I've been asked to comment here about the tags. Please note Wikipedia:Verifiability. I see that some of the content has come from the Free On-line Dictionary of Computing which I assume to be a good and reliable source. In short that material which comes from that source should be referenced inline (ie using <ref> tags). Any material that has been added which can be verified from that source can also be reference from that source. (however I only found this http://foldoc.org/S-Video though there may be more)
Ultimately all statements should be referenced from reliable sources, the article is clearly not up standard in that respect. For an example of a page that is fully referenced see hdmi. The tag therefore is applicable - the article needs referencing, and the tags are appropriate eg this version [5] - some of the material covered is quite technical and needs to be properly cited. If unreference material is being "challenged and removed" is is fair to request that it be moved to this talk page so that editors can examine and possibly reference and re-add it.
In practice the solution is to solve the problem by referencing the article.Sf5xeplus (talk) 02:15, 18 January 2011 (UTC)
A few points that have been mentioned that I would like to reiterate. The first is that Doniago is absolutely correct in asking if there are policy based reasons for the tags to be removed. There are of course none. As Sf5xeplus points out, the sources are available, and it is easy to fix the problem instead of complaining about the tags. The fact that the content has remained unchallenged for so long is a moot point, it says in an abundance of places around the wiki that unsourced content can be removed at anytime. The tags are no reason to take offense, they are not a reflection on any work done. The tags found on this page are very common and it is very unlikely they are effecting the experience of the readers of this page. The fact that large portions of Wikipedia are unsourced has no bearing on the content or tagging of this specific article. Lastly, to the IP editor, you may find editors here much more willing to work with you if you focus on article content and refrain from attacking them based on your perceptions.

The main article contains too much waffle. It goes on to talk about the Nintendo 64 and how you can modify it to output RGB by a german company?
while this is vaguely tied to svideo wouldnt it be better to remove all of this and put it in the nintendo 64 article and focus on s-video isntead. —Preceding unsigned comment added by 94.171.217.102 (talk) 18:06, 23 January 2011 (UTC)
Archiving unsourced material here. Despite the discussions above this information has remained without sourcing. Please feel free to add this material back into the article with proper sourcing. Doniago (talk) 15:00, 23 February 2011 (UTC)
9-pin Video In/Video Out

=== 9-pin Video In/Video Out ===
These are used on graphics systems that feature the ability to input video as well as output it. Again, there is no standardization between manufacturers as to which pin does what (also given that there 2 known variants of the connector in use). As can be seen from the diagram above, although the S-Video signals are available on the corresponding pins, neither variant of the connector will accept an unmodified 4-pin S-video plug, though they can be made to fit by removing the key from the plug. In this latter case, it becomes all too easy to misalign the plug when inserting it with consequent damage to the small pins.

S-Video is commonly used throughout the world. It is found on consumer TVs, DVD players, high-end video cassette recorders, digital TV receivers, DVRs, game consoles, graphics cards and projectors. It is in the process of being superseded by component video and digital video standards, such as DVI and HDMI.
S-Video cables are used for computer-to-TV output for business or home use. Because it is very simple to convert S-Video to composite signal, many electronics retailers offer converter adapters. The wiring is:
Conversion is likely to degrade image quality, but it does allow connection between otherwise incompatible devices. Converting composite signal to S-Video is harder, because once luminance and chrominance are merged, it is hard to separate them while minimising loss. High quality comb filters are commonly used to separate the signals. Due to lack of bandwidth, S-Video connections are generally not considered suitable for high-definition video signals. As a result, HD sources are generally connected to a monitor by way of analogue component video or wideband digital methods (usually HDMI or DVI). However, when using older monitors with S-Video but without HDMI and DVI, some graphics cards have full display (including bootup display) with HDMI, DVI, and S-Video and partially full display (displaying only after the OS boots up) with component and composite. So in this case, S-Video works well, as it allows the user to see the display in the event that they need to adjust settings in the CMOS. The situation with VCRs is a bit unusual: the common S-Video connector was designed for Super VHS and Hi8 VCRs as a high-bandwidth video connection and has been used for the same purpose on a great number of other consumer devices, coming into greatest prominence with the rise of the DVD format. Many digital (and all Hi-8 and S-VHS-C) camcorders support S-Video as well. Standard VHS VCRs do not put out a high enough resolution signal to saturate an S-Video connection, and therefore most such units (even those in combination units with DVD players, which commonly use S-Video or component outputs) require the output from the VHS deck to go through a composite video or RF connection. |
History

==History==
In 1987, JVC's release of S-VHS introduced the S-Video cable standard. With these cables, the S-VHS video cassette systems play with their full potential, completing the improved definition and resolution into a compatible TV. Due to low market penetration of television sets and video devices equipped with S-Video ports, the format failed to become a mainstream image standard and remained in the niche high-end home cinema market. In the late 1990s, big-screen television sets began shipping with S-Video option in input ports, thus increasing the number of supportable electronic devices such as DVD players, satellite receivers, and video game consoles. The format gained some popularity as a better alternative to composite video inputs. S-Video was also adopted in the graphics card market in the early 2000s to provide a video output from computers to TVs. The introduction of component video, offering a better image and backward compatibility, replaced S-Video as the default alternative to the composite video on many high-end cards. Laptops commonly included an S-Video output, but since the mid-2000s, this function on new models has been replaced by DisplayPort or HDMI outputs. Etymologically, the word S-Video has several denotations: Super Video (complementing Super VHS), Separated Video, and S-VHS cable. |

Before the mini-DIN plug became standard, S-Video signals were often carried through different types of connectors. For example, the Commodore 64 home computer of the 1980s, one of the first widely available devices to feature an output similar to S-Video. It used an eight-pin DIN connector on the computer end and a pair of phono plugs on the monitor end to hookup separate luminance and chrominance, the latter with a higher signal level than standard S-video. (Also available via third-party vendors was an eight-pin DIN-to-4-pin mini-DIN to connect the Commodore directly to a television.) The S-Video connector is the most common video-out connector on older laptop computers; however, many devices with S-Video outputs also have composite outputs.
The Atari 800 home computer featured S-Video outputs in 1979 (three years before the Commodore 64), via a five-pin DIN plug. At least some Fujitsu laptops (S-7020, S-7110) use so-called mini S-Video connector for TV-Out. This mini S-Video connector is actually a 3.5mm TRS connector where tip and ring carry Y/C, both using the sleeve as ground. Such a mini S-Video is rare, and it is very difficult to obtain a proprietary cable for it. In Japan, MSX 2+ and MSX Turbo-R models from Panasonic featured standard S-Video output, some X68000 computers from Sharp (like the X68030) also feature S-Video output. |
That statement is just wrong.
JVC, who introduced the 4-pin DIN connector pictured that is the de-facto standard for Y/C connectors on consumer A/V equipment in much of the world (outside of where SCART-only is mandated) uses the terms "S-VHS Plug", "S-VHS cable", and "Super Video" interchangeably with "S-Video" to refer to it to this day.

The article mentions the cable should be twisted pair like CAT-5 so both luminance and chrominance signals are paired with ground. What is the source for this? S-Video is no different from any other analog video connection, so coaxial cable with 75 ohms impedance should be used, one for Y and one for C signal. — Preceding unsigned comment added by 91.153.27.229 (talk) 12:07, 4 November 2011 (UTC)
When I used a CRT TV I used an S-video link from the DVD player so that I could feed the sound to a stereo that offered far better sound fidelity. For someone who did not have surround sound, the stereo offered far better sound than did the TV set. The S-cable was adequate for the quality of the picture. But for the much-better picture with an HDTV, let alone a Blu-Ray player an S-cable is not so adequate. There may be other ways to get high-quality sound than a dedicated stereo system that one uses for music...
We are discussing an obsolete technology in the form of a TV cable. An HDMI cable does the job far better, but one can't hook one up to one of the old-fashioned analogue TVs. For people who still have an analogue TV in use it might still be adequate.
My observation on its use is my experience... I think that my ears are good enough to distinguish sound quality between an analogue 19" TV set and a stereo system and that my eyes can discern a difference between HDTV and the old CRT TVs. Pbrower2a (talk) 12:40, 29 July 2013 (UTC)
Does anybody the exact horizontal resolution of the color signal for S-video? I When I read this article, it says "S-video has better image clarity than composite video, but has lower color resolution than component video". I also wonder if Composite video and S-video share the same amount of detail you get in the chrominance signal you get from each other. I can't seem to find a source that explains what the maximum horizontal you get with S-Video chrominance nor the how much horizontal resolution there is in a an analog Y-Pb-Pr component video signal. It'd be nice to know so I can understand how big of gap there is between S-Video, and Component Video in terms of image clarity. TommyMunoz2002 (talk) 21:58, 22 July 2022 (UTC)
This page use to say the amount of horizontal resolution S-Video supports natively but now it doesn't. It just says S-Video provides better image quality than composite video but lower color resolution than component video. This Wikipedia page should say how much color resolution S-Video supports, the amount of bandwidth the chrominance signal supports, and how many color changes S-Video supports per-scanline.
