Contents • • • • • • • • • • • Technical information [ ] Like VHS, the S-VHS format uses a color under scheme. S-VHS improves (luma) resolution by increasing luminance. Increased bandwidth is possible because of increased luminance from 3.4 (MHz) to 5.4 MHz. Increased luminance bandwidth produces a 60% improvement in (luminance) picture detail, or a horizontal resolution of 420 vertical lines per picture height – versus VHS's 240 lines. The often quoted horizontal resolution of 'over 400' means S-VHS captures greater picture detail than even analog cable and broadcast TV, which is limited to about 330 (TVL). In practice, when on S-VHS equipment, the improvement over VHS is quite noticeable. Yet, the trained eye can easily spot the difference between and a S-VHS recording of it.

This is because S-VHS does not improve other key aspects of the video signal, particularly the (chroma) signal. In VHS, the chroma carrier is both severely and rather, a limitation that S-VHS does not address. Poor color resolution was a deficiency shared by S-VHS's contemporaries, such as and ED-Beta – all of which were limited to 0.4 megahertz or 30 TVL resolution. Regarding, S-VHS retains VHS's conventional linear () and (Hi-Fi) – (AFM) soundtracks. Some professional S-VHS decks can record a (PCM) track (stereo 48 kHz), along with the normal video and Hi-Fi stereo and mono analog audio. As an added bonus, due to the increased bandwidth of S-VHS, data () signals can be recorded along with the normal video signal.

As a result, this teletext data is also able to be decoded and displayed on-screen as an overlay of the conventional TV picture (though not on standard VHS machines). A suitably teletext-equipped receiver/decoder (TV, PC card, etc.) displays the recorded teletext data information as if the video were being viewed as a real-time live broadcast. Hardware [ ] S-VHS (VCRs) and cassette tapes are nearly identical in appearance and operation, and with VHS.

Older VHS VCRs cannot play back S-VHS recordings at all, but can record onto an S-VHS tape in the basic VHS format. [ – ] [ ] Newer VHS VCRs, depending upon their specification, offered a feature called S-VHS quasi-playback or Super Quasi-Play Back, abbreviated to SQPB.

SQPB lets basic VHS players view (but not record) S-VHS recordings, though reduced to the lesser VHS quality. This feature is useful for viewing S-VHS recordings which used either the full-size S-VHS videotape cassette or the smaller videotape cassette. Later model S-VHS VCRs offered a recording option called. S-VHS ET is a further modification of the VHS standards that permitted near S-VHS quality recordings on more common and less expensive basic VHS tapes.

S-VHS ET recordings can be viewed on most SQPB-equipped VHS VCRs and S-VHS VCRs. To get the most benefit from S-VHS, a direct video connection to the monitor or TV is required, ideally via an or -enabled connection. Media [ ] In order to take advantage of the enhanced capabilities of the S-VHS system, i.e., for the best recordings and playback, an S-VHS VCR requires S-VHS cassettes. These have a different oxide media formulation for higher magnetic coercivity. S-VHS video cassettes are sensed and identified by the video cassette recorder via a specific internal profile within a hole in the underside of the S-VHS video cassette body.

Videophiles were the first to theorize that since the only distinguishing feature of an S-VHS tape is a small 3 mm hole on the underside of the video cassette, it should be possible to use more common and inexpensive VHS tapes by duplicating that hole. However, S-VHS cassettes also contain a higher grade and of tape stock to effectively record the higher video bandwidth offered by S-VHS.

S-VHS ET [ ] JVC also introduced an S-VHS ET system on its S-VHS consumer decks, allowing the use of normal VHS tapes for S-VHS recording, by slightly modifying the S-VHS recording specs while still retaining compatibility so that S-VHS ET tapes could be played with non-ET S-VHS VCRs. Technically, in S-VHS ET mode, the recording circuit is altered with: • Change of the W/D clip level (reducing the white clip level from 210% in SVHS to 190% in SVHS ET) • Change of the main emphasis characteristics (changing the frequency responses) • Change of the recording level (Y and C) and recording current Shadow of VHS [ ] Despite its designation as the logical successor to VHS, S-VHS did not come close to replacing VHS.

In the home market, S-VHS failed to gain significant. For various reasons, consumers were not interested in paying more for an improved picture. Likewise, S-VHS rentals and movie sales did very poorly. A few pre-recorded movies were released to S-VHS, but poor market acceptance prompted studios to transition their high-end product from S-VHS to, and then onto. In the role, the smaller form S-VHS-C camcorder enjoyed limited success among home video users. It was more popular for the amateur video industry, as it allowed for at least second generation copies at reasonable quality (necessary for editing). JVC,, and Sony have sold industrial S-VHS decks for amateur and semi-professional production use.

Some stations and other low-budget venues used the S-VHS format, both for acquisition and subsequent studio editing, but the network studios largely avoided S-VHS, as descendants of the more expensive format had already become a. S-VHS-C competed directly with, the latter offering smaller cassettes, longer running time, and ultimately selling much better. A number of colleges and universities also used S-VHS as a teaching tool for students, as the tapes cost less and offered more recording time than Betacam SP tapes, and yet students could still be trained on professional-level equipment. I Think My Tailbone Is Broken.

Plus on the professional level in the US a number of local access TV stations, and in Canada local cable channels used S-VHS in the 1990s to record and playback local programs, such as city councils and Christmas parades. For most of these stations, while the 3/4 U-Matics that they had been using were being phased out, but digital video was still years away, S-VHS was used to record from the composite setups that were still in place for U-Matic production. As of 2007, consumer S-VHS VCRs were still available, but difficult to find in retail outlets. The largest VCR manufacturers, such as () and, gradually moved to, and hard-disk based (DVRs). Combination DVD/VCR units rarely offered S-VHS format standard, only VHS. In the mainstream consumer camcorder market,, DVD, and—eventually—solid state memory-based camcorders replaced S-VHS-C camcorders. Digital camcorders generally outperform S-VHS-C units in most technical aspects: audio/video quality, recording time, lossless duplication, and form-factor.

The themselves are available, mostly by mail order or online, but are vanishingly rare in retail channels, and substantially more expensive than high-quality standard VHS media. S-VHS vs ED-Beta [ ] Shortly after the announcement of S-VHS, responded with an announcement of Extended Definition (ED-Beta). S-VHS was JVC's next generation video format designed to dominate the competing format (which already offered better-than-VHS quality). Not to be outdone, Sony developed as their next generation competitor to S-VHS. In terms of video performance, ED-Beta offered even greater luminance bandwidth than S-VHS – 500 (TVL) of horizontal resolution per picture height, versus S-VHS's or Laserdisc's 420 TVL; putting ED-Beta nearly on par with professional digital video formats (520 TVL). However, chroma performance was far less spectacular, as neither S-VHS nor ED-Beta exceeded 0.4 megahertz or ~30 TVL maximum, whereas NTSC broadcast has a chroma resolution of ~120 TVL, and DVD has a chroma resolution of ~240 TVL.

S-VHS was used in some TV stations for inexpensive 'on the spot' camcorder capture of breaking news, however it was not suitable for multi-generational (studio) use. In terms of audio performance, both VHS and Beta offered analog Hi-Fi stereo of outstanding quality. Rather than re-invent the wheel, both S-VHS and ED-Beta re-used the AFM schemes of their predecessors without change. Professional S-VHS decks did offer digital PCM audio, a feature not matched by ED-Beta decks. In markets, depth multiplexed audio was used for both formats. Market, the mainstream consumer market had largely ignored the release of S-VHS. With the Betamax market already in sharp decline, a 'format war' for the next generation of video simply did not materialize.

Sony discontinued the ED-Beta product line in the U.S. Market after less than two years, handing S-VHS a victory by default, if it can even be called that. (VHS decks continued to outsell S-VHS decks until the end of the VCR product life cycle.) There is anecdotal evidence that some TV stations purchased ED-Beta equipment as a low-cost alternative to professional equipment, prompting speculation that Sony's management took steps to prevent its consumer (ED-Beta) division from cannibalizing the sales of its more lucrative professional video division. Nevertheless, it is clear to all that by the time of ED-Beta's introduction, VHS had already won a decisive victory, and no amount of competition on behalf of ED-Beta could regain the home video market. Home use [ ] Getting the most benefit from S-VHS required a direct video connection to the monitor, ideally via an connection. However, older lacked S-Video or even any AV inputs.

Nevertheless, viewing an S-VHS recording through a VCR's built-in yields a discernible quality improvement over VHS. Download Full Length Movies. It is not unusual to see the term S-VHS incorrectly used to refer to connectors (also called Y/C connectors), even in printed material.

This may be due to S-VHS having been one of the more common consumer video products equipped with the S-Video connector. However, S-Video connectors became common on many other video devices: DVD players and recorders, and Hi8 camcorders, cable/satellite set-top boxes, TV-compatible video outputs on computers and video game consoles, and inputs on TV sets themselves. Where the S- in S-VHS means 'super', the S- in S-Video refers to the 'separated' luminance and chrominance signals. Use for digital audio [ ].

An Alesis ADAT XT 8-channel digital audio recorder In 1991, introduced, an eight-track digital audio recording system that used S-VHS cassettes. An ADAT machine recorded eight tracks of uncompressed audio material in 16-bit (later 20-bit) resolution.

The recording time was one-third of the cassette's nominal playing time, e.g., a 120 min S-VHS cassette held 40 minutes of eight-track audio. Also produced the V-Eight and the V-Twenty-Four digital multitrack recorders that utilised S-VHS tape cassettes for 8-track, and 24-track digital audio recording, at a significantly lower cost than their DASH reel-to-reel digital recorders. The videotape transports were made for Studer by Matsushita.
