Talk:S-VHS
From Wikipedia, the free encyclopedia
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)

- 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)

- 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)

[edit] 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)
[edit] 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)
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)
[edit] 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).
- 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.
[edit] 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)
