Talk:S-VHS

Is it just me or does S-video standfor SEPARATED video ? mean Y/C on tape and thus , better quality

No, S-VHS stands for "SuperVHS." An S-VHS recording is no more separated than VHS; both use color-under recording, with the chroma subcarrier shifted to a low frequency and the luma signal recorded via FM on a higher-frequency carrier. SuperVHS achieves greater luma bandwidth simply by using a higher carrier frequency and wider deviation in the FM. S-Video, on the other hand, refers to a signal, connector, and cable that carries the luma and chroma on separate conductors -- hence "separate video." Jeh 23:08, 29 March 2006 (UTC)[reply]

The answer to the top question is YES! The question was asking about S-video connetors, not S-VHS. Indeed the S here stands for Separated video, the luma and chroma are separated on this type of connector. Some idiots think that the connector is a SVHS connector which it isn't, even some Panasonic SVHS recorder manuals are at pains to point this out. Colin99 20:46, 22 April 2006 (UTC)[reply]

IF the question had been about the S-video connector, then you would be correct. However I think the OP was asking about the tape format, even though he says "S-video", because of his wording "....mean Y/C ON TAPE...". It seems very clear to me that the question is addressing the tape format and not the connector. JVC contributed to this confusion by creating a logo, a graphic rendition of "S-VHS", which they used on tape and tape equipment. Jeh 22:19, 17 February 2007 (UTC)[reply]

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.

PAL information needed

No mention of PAL, only NTSC specific. Could somebody with more knowledge please expand this article? Peter S. 18:51, 5 April 2006 (UTC)[reply]

Is S-VHS demonstrably superior to VHS in a domestic environment?

We have something approaching a contradiction. Top paragraph says: "when timeshifting TV programs on S-VHS equipment, the improvement over VHS is not noticeable" The bottom paragraph says: "Nevertheless, viewing an S-VHS recording through a VCR's built-in RF modulator yields a discernable perceived quality improvement over VHS"

They're not quite saying the same thing, the first is talking about timeshifting and the latter about an RF hookup (which is presumably used for timeshifting, what else?). The truth is of course that it is subjective. Some people can see the difference between VHS and SVHS, some can't. It's influenced by the tape, recording source, monitor and make/model/condition of machine. I've seen one set of VHS recordings (only one mind you!) which was so clear, noiseless, and carefully made as to subjectively surpass many recordings made by low-end S-VHS decks. Often however VHS is a fuzzy noisy mess and S-VHS is a less noisy fuzzy mess.

Without making it all too wordy, we should modify these phrases to ensure that both tend to point to a superior performance of S-VHS over VHS which may or may not be immediately obvious depending upon various factors. Volunteers to clean this up? Colin99 15:50, 2 January 2007 (UTC)[reply]

I made a first change, very easily, by changing the first bit to say the improvement IS noticeable. It certainly is to me. Jeh 22:18, 17 February 2007 (UTC)[reply]

If you record a foreign movie or TV show that has subtitles, the difference between VHS and Super VHS is immediately obvious. In VHS the subtitles take-on a blurry appearance and are difficult to read, whereas the Super VHS preserves them perfectly. ----- 00:06, 13 April 2009 (UTC)

S-VHS, S-VHS ET, SQPB

Could someone with knowledge in this area expand the explanations of S-VHS ET and SQPB, paying particular attention to where S-VHS recordings on S-VHS medium is viewable (only S-VHS decks?) and where S-VHS ET recordings on "normal" VHS medium is viewable (is it viewable on standard VHS decks or only those that support a special "S-VHS ET" format?). What does SQPB stand for and what is it (medium, technology, recording format, etc)? Also the sentence "As a sidenote, most S-VHS VCRs can also make VHS recordings on S-VHS tape, and conversely, conventional VHS VCRs can record on S-VHS videotape" is a bit wordy and confusing as to its exact meaning. —The preceding unsigned comment was added by 68.153.109.3 (talk) 20:07, 13 April 2007 (UTC).[reply]

I've seen in a few places that most VHS VCRs made since 1995 can play S-VHS recordings made on S-VHS tapes, though the output is only VHS quality. I've also read that the "ET" S-VHS recordings 'may not' play on VHS VCRs.

VHS has 3 megahertz luminance bandwidth while S-VHS has 5.25 megahertz bandwidth. Old VHS decks will read the greater than 3 megahertz recording, but won't know how to handle it, so they display "garbage" on the screen. VHS decks with Super-Quasi-PlayBack will use low-pass filters to remove anything above 3 megahertz, thereby cleaning up the image. ---- Theaveng (talk) 11:31, 21 November 2008 (UTC)[reply]

Combo decks

JVC, Matsushita(Panasonic), and at least one other company made combo decks that had both an S-VHS transport and a MiniDV transport. Many of them also included a Firewire port for connection to a computer. What I've never been able to find out is whether or not they provided computer control of the the S-VHS transport or direct digitizing from it, or if to digitize from VHS one had to first copy to a MiniDV tape. —Preceding unsigned comment added by 208.100.251.47 (talk) 10:48, 5 September 2007 (UTC)[reply]

from S-VHS, via Y-C, to S-Video.

SVHS is the follow-up of the video recording VHS, a video-recording standard, the old competitor of BETAMAX(SONY) and of VIDEO2000(PHILIPS). I am a PHILIPS man and in those days the competitors trick was to use a new way of transferring the video from the recorder to the TV. Instead of offering the usual composite signal of both Colour and Video Base band Signals: CVBS, where both signals: Colour and Black and White were mixed together, they send both signals separated to the TV. This excluded the necessity of using a signal-separation filter in the TV, thereby decreasing cross-interferences between both signals and.. improving Bandwidth and off course...... improving the definition of picture details! Because of that, PHILIPS and SONY just called the same idea: Y/C-signal-transfer. Y for video black/white and C for Color. I think the S originally stood for 'super', but the word 'separate' is actually better, because of the nature of the video-connection. So SVHS is correctly replaced by S-Video, forgetting the recording history. —Preceding unsigned comment added by 77.248.104.2 (talk) 20:40, 9 April 2009 (UTC)[reply]

S-video predates Super VHS by about ten years. In fact by the time S-VHS arrived, studios were already using component video as part of the Betacam format. ----- 00:08, 13 April 2009 (UTC)

"Needs citations" template

Editor Hinata removed the "needs citations" parameter from the "multiple issues" template, saying that the article does "site[sic] references". And has now done so twice.

WP policy requires that inline citations (and it's Citations, by the way, not Sitations) be present for "any material challenged or likely to be challenged, and for all quotations" (see WP:CITE, WP:V), and that citations are strongly recommended for everything else: "All material in Wikipedia articles must be attributable to a reliable published source to show that it is not original research".

The policy does also state that "in practice not everything need actually be attributed", but that does not mean that two inline citations are sufficient for an article of about 20 paragraphs. Ideally it means a citation for every statement or claim of fact.

And by the way... the two citations that are present here do not even directly apply to the article topic! One is used to justify a statement regarding poor chroma resolution of other video tape formats, and the other for the resolution of HDV!

Sorry but the notion that this article has enough references or inline citations is completely unsustainable. I did change the parameter from "unreferenced" ("it does not cite any references or sources") to "citations missing" ("It is missing citations or footnotes"), as that is a better fit. Jeh (talk) 23:17, 21 September 2010 (UTC)[reply]

Backed up, Jeh. I was going to add a "citation needed" tag on the "Modifying VHS Cassettes for S-VHS recordings" section, when I noticed that the need for citations was global to the article. Twipley (talk) 17:53, 22 September 2010 (UTC)[reply]

I'll come back to the article with refs over the weekend. Plenty of RS available on the subject itself. As for the homegrown mods, it's better be reduced to just one line: "Yes, it was possible, no, it didn't work". Get real, it's all in the past, who really cares? It's like spending hours describing overclocking on a 286 (WTF is a 286, mommy ...). East of Borschov 09:29, 23 September 2010 (UTC)[reply]
