The recorded frequency range was dependent on the linear tape speed. S-VHS tapes can give better audio and video quality, because the tapes are designed to have almost twice the bandwidth of VHS at the same speed.

Sound cannot be recorded on a VHS tape without recording a video signal, even in the audio dubbing mode. If there is no video signal to the VCR input, most VCRs will record black video and generate a control track while the sound is being recorded.

Some early VCRs record audio without a control track signal; this is of little use, because the absence of a signal from the control track means that the linear tape speed is irregular during playback.

More sophisticated VCRs offer stereo audio recording and playback. Linear stereo fits two independent channels in the same space as the original mono audiotrack.

While this approach preserves acceptable backward compatibility with monoaural audio heads, the splitting of the audio track degraded the signal's SNR, causing objectionable tape hiss at normal listening volume.

This dynamically boosts the mid-frequency band of the audio program on the recorded medium, improving its signal strength relative to the tape's background noise floor, then attenuates the mid-band during playback.

Dolby B is not a transparent process, and Dolby-encoded program material exhibits an unnatural mid-range emphasis when played on VCRs that are not made to work with this form of noise reduction.

Another option is to use noise reduction similar to that of DBX—that is, by recording with high volume but with a compressed dynamic range.

On playback the decompression will yield original audio; because weaker signals are attenuated, the hiss can also be significantly attenuated.

Has this been done, or is somebody just brainstorming at Wikipedia? High-end consumer recorders take advantage of the linear nature of the audio track, as the audio track could be erased and recorded without disturbing the video portion of the recorded signal.

Hence, "audio dubbing" and "video dubbing", where either the audio or video are re-recorded on tape without disturbing the other , were supported features on prosumer linear video editing -decks.

Without dubbing capability, an audio or video edit could not be done in-place on master cassette, and requires the editing output be captured to another tape, incurring generational loss.

Studio film releases began to emerge with linear stereo audiotracks in From that point onward nearly every home video release by Hollywood featured a Dolby-encoded linear stereo audiotrack.

However, linear stereo was never popular with equipment makers or consumers. Another linear control track , at the tape's lower edge, holds pulses that mark the beginning of every frame of video; these are used to fine-tune the tape speed during playback, so that the high speed rotating heads remained exactly on their helical tracks rather than somewhere between two adjacent tracks known as " tracking ".

The control track is also used to hold index marks , which were normally written at the beginning of each recording session, and can be found using the VCR's index search function: this will fast-wind forward or backward to the n th specified index mark, and resume playback from there.

At times, higher-end VCRs provided functions for the user to manually add and remove these marks [43] [44] — so that, for example, they coincide with the actual start of the television program — but this feature later became hard to find.

By the late s, some high-end VCRs offered more sophisticated indexing. For example, Panasonic's Tape Library system assigned an ID number to each cassette, and logged recording information channel, date, time and optional program title entered by the user both on the cassette and in the VCR's memory for up to recordings with titles.

VHS Hi-Fi audio is achieved by using audio frequency modulation AFM , modulating the two stereo channels L, R on two different frequency-modulated carriers and embedding the combined modulated audio signal pair into the video signal.

To avoid crosstalk and interference from the primary video carrier, VHS's implementation of AFM relied on a form of magnetic recording called depth multiplexing.

The modulated audio carrier pair was placed in the hitherto-unused frequency range between the luminance and the color carrier below 1.

Subsequently, the video head erases and re-records the video signal combined luminance and color signal over the same tape surface, but the video signal's higher center frequency results in a shallower magnetization of the tape, allowing both the video and residual AFM audio signal to coexist on tape.

During playback, VHS Hi-Fi recovers the depth-recorded AFM signal by subtracting the audio head's signal which contains the AFM signal contaminated by a weak image of the video signal from the video head's signal which contains only the video signal , then demodulates the left and right audio channels from their respective frequency carriers.

The end result of the complex process was audio of high fidelity, which was uniformly solid across all tape-speeds EP, LP or SP.

Since JVC had gone through the complexity of ensuring Hi-Fi's backward compatibility with non-Hi-Fi VCRs, virtually all studio home video releases produced after this time contained Hi-Fi audio tracks, in addition to the linear audio track.

The sound quality of Hi-Fi VHS stereo is comparable to some extent to the quality of CD audio, particularly when recordings were made on high-end or professional VHS machines that have a manual audio recording level control.

This high quality compared to other consumer audio recording formats such as compact cassette attracted the attention of amateur and hobbyist recording artists.

Home recording enthusiasts occasionally recorded high quality stereo mixdowns and master recordings from multitrack audio tape onto consumer-level Hi-Fi VCRs.

However, because the VHS Hi-Fi recording process is intertwined with the VCR's video-recording function, advanced editing functions such as audio-only or video-only dubbing are impossible.

A short-lived alternative to the hifi feature for recording mixdowns of hobbyist audio-only projects was a PCM adaptor so that high-bandwidth digital video could use a grid of black-and-white dots on an analog video carrier to give pro-grade digital sounds though DAT tapes made this obsolete.

Some VHS decks also had a "simulcast" switch, allowing users to record an external audio input along with off-air pictures.

Some televised concerts offered a stereo simulcast soundtrack on FM radio and as such, events like Live Aid were recorded by thousands of people with a full stereo soundtrack despite the fact that stereo TV broadcasts were some years off especially in regions that adopted NICAM.

Other examples of this included network television shows such as Friday Night Videos and MTV for its first few years in existence.

Likewise, some countries, most notably South Africa , provided alternate language audio tracks for TV programming through an FM radio simulcast.

The considerable complexity and additional hardware limited VHS Hi-Fi to high-end decks for many years. Even then, most customers were unaware of its significance and merely enjoyed the better audio performance of the newer decks.

Due to the path followed by the video and Hi-Fi audio heads being striped and discontinuous—unlike that of the linear audio track—head-switching is required to provide a continuous audio signal.

While the video signal can easily hide the head-switching point in the invisible vertical retrace section of the signal, so that the exact switching point is not very important, the same is obviously not possible with a continuous audio signal that has no inaudible sections.

Hi-Fi audio is thus dependent on a much more exact alignment of the head switching point than is required for non-HiFi VHS machines.

Misalignments may lead to imperfect joining of the signal, resulting in low-pitched buzzing. Another issue that made VHS Hi-Fi imperfect for music is the inaccurate reproduction of levels softer and louder which are not re-created as the original source.

The audio system both linear and AFM is the same. S-VHS made little impact on the home market, but gained dominance in the camcorder market due to its superior picture quality.

Since VHS-C tapes are based on the same magnetic tape as full-size tapes, they can be played back in standard VHS players using a mechanical adapter, without the need of any kind of signal conversion.

The magnetic tape on VHS-C cassettes is wound on one main spool and uses a gear wheel to advance the tape.

The adapter is mechanical, although early examples were motorized, with a battery. It has an internal hub to engage with the VCR mechanism in the location of a normal full-size tape hub, driving the gearing on the VHS-C cassette.

Also, when a VHS-C cassette is inserted into the adapter, a small swing-arm pulls the tape out of the miniature cassette to span the standard tape path distance between the guide rollers of a full-size tape.

This allows the tape from the miniature cassette to use the same loading mechanism as that from the standard cassette.

Ultimately neither format "won" and both have been superseded by digital high definition equipment. There is also a JVC-designed component digital professional production format known as Digital-S , or officially under the name D9, that uses a VHS form factor tape and essentially the same mechanical tape handling techniques as an S-VHS recorder.

This format is the least expensive format to support a Sel-Sync pre-read for video editing. It has now been superseded by high definition formats.

These devices served the sole purpose of rewinding VHS tapes. Proponents of the rewinders argued that the use of the rewind function on the standard VHS player would lead to wear and tear of the transport mechanism.

The rewinder would rewind the tapes smoothly and also normally do so at a faster rate than the standard rewind function on VHS players.

However some rewinder brands did have some frequent abrupt stops, which occasionally led to tape damage.

Some devices were marketed which allowed a personal computer to use a VHS recorder as a data backup device. VHS can record and play back all varieties of analog television signals in existence at the time VHS was devised.

However, a machine must be designed to record a given standard. Typically, a VHS machine can only handle signals using the same standard as the country it was sold in.

Since the s, dual and multi-standard VHS machines, able to handle a variety of VHS-supported video standards, became more common.

Dedicated multi-standard machines can usually handle all standards listed, and some high-end models could convert the content of a tape from one standard to another on the fly during playback by using a built-in standards converter.

A small number of VHS decks are able to decode closed captions on video cassettes before sending the full signal to the set with the captions.

A smaller number still are able, additionally, to record subtitles transmitted with world standard teletext signals on pre-digital services , simultaneously with the associated program.

S-VHS has a sufficient resolution to record teletext signals with relatively few errors. It uses the Lee font, designed by Leo Weisz.

VHS was popular for long-form content, such as feature films or documentaries, as well as short-play content, such as music videos, in-store videos, teaching videos, distribution of lectures and talks, and demonstrations.

VHS instruction tapes were sometimes included with various products and services, including exercise equipment, kitchen appliances, and computer software.

VHS was the winner of a protracted and somewhat bitter format war during the late s and early s against Sony's Betamax format as well as other formats of the time.

Betamax was widely perceived at the time as the better format, as the cassette was smaller in size, and Betamax offered slightly better video quality than VHS — it had lower video noise, less luma-chroma crosstalk , and was marketed as providing pictures superior to those of VHS.

However, the sticking point for both consumers and potential licensing partners of Betamax was the total recording time. Very high-end Betamax machines still supported recording in the Beta I mode and some in an even higher resolution Beta Is Beta I Super HiBand mode, but at a maximum single-cassette run time of [with an L cassette].

Because Betamax was released more than a year before VHS, it held an early lead in the format war. However, by , United States' Betamax sales had dipped to only percent of all sales.

Some, including Sony's founder Akio Morita, say that it was due to Sony's licensing strategy with other manufacturers, which consistently kept the overall cost for a unit higher than a VHS unit, and that JVC allowed other manufacturers to produce VHS units license-free, thereby keeping costs lower.

The video cassette recorder was a mainstay in television -equipped American and European living rooms for more than twenty years from its introduction in The home television recording market, as well as the camcorder market, has since transitioned to digital recording on solid-state memory cards.

Though In the mids, several retail chains in the United States and Europe announced they would stop selling VHS equipment.

The last known company in the world to manufacture VHS equipment was Funai of Japan, who produced video cassette recorders under the Sanyo brand in China and North America.

Funai ceased production of VHS equipment in July , citing falling sales and a shortage of components. Despite the decline in both VHS players and programming on VHS machines, they are still owned in some households worldwide.

Those who still use or hold on to VHS do so for a number of reasons, including nostalgic value, ease of use in recording, keeping personal videos or home movies , watching content currently exclusive to VHS, and collecting.

Some expatriate communities in the United States also obtain video content from their native countries in VHS format. Although VHS has been discontinued in the United States, VHS recorders and blank tapes were still sold at stores in other developed countries prior to digital television transitions.

A market for pre-recorded VHS tapes has continued, and some online retailers such as Amazon still sell new and used pre-recorded VHS cassettes of movies and television programs.

None of the major Hollywood studios generally issue releases on VHS, the last major studio film to be released in the format in the United States, other than as part of special marketing promotions, was A History of Violence in However, there have been a few exceptions.

For example, The House of the Devil was released on VHS in as an Amazon-exclusive deal, in keeping with the film's intent to mimic s horror films.

Though occasionally showing compression artifacts and color banding that are common discrepancies in digital media, the durability and longevity of a VCD depends on the production quality of the disc, and its handling.

The data stored digitally on a VCD theoretically does not degrade in the analog sense like tape. In the disc player, there is no physical contact made with either the data or label sides.

When handled properly, a VCD will last a long time. Since a VCD can hold only 74 minutes of video, a movie exceeding that mark has to be divided into two or more discs.

Despite DVD's better quality typical horizontal resolution of versus lines per picture height , and the availability of standalone DVD recorders, VHS is still used in home recording of video content.

The commercial success of DVD recording and re-writing has been hindered by a number of factors including:. High-capacity digital recording systems are also gaining in popularity with home users.

These types of systems come in several form factors:. These types of systems provide users with a no-maintenance solution for capturing video content.

Customers of subscriber-based TV generally receive electronic program guides, enabling one-touch setup of a recording schedule.

Hard disk—based systems allow for many hours of recording without user-maintenance. Often considered an important medium of film history, the influence of VHS on art and cinema was highlighted in a retrospective staged at the Museum of Arts and Design in The documentary film Rewind This!

Dedicated multi-standard machines can usually handle all standards listed, and some high-end models could convert the content of a tape from one standard to another on the fly during playback by using a built-in standards converter.

A small number of VHS decks are able to decode closed captions on video cassettes before sending the full signal to the set with the captions.

A smaller number still are able, additionally, to record subtitles transmitted with world standard teletext signals on pre-digital services , simultaneously with the associated program.

S-VHS has a sufficient resolution to record teletext signals with relatively few errors. It uses the Lee font, designed by Leo Weisz.

VHS was popular for long-form content, such as feature films or documentaries, as well as short-play content, such as music videos, in-store videos, teaching videos, distribution of lectures and talks, and demonstrations.

VHS instruction tapes were sometimes included with various products and services, including exercise equipment, kitchen appliances, and computer software.

VHS was the winner of a protracted and somewhat bitter format war during the late s and early s against Sony's Betamax format as well as other formats of the time.

Betamax was widely perceived at the time as the better format, as the cassette was smaller in size, and Betamax offered slightly better video quality than VHS — it had lower video noise, less luma-chroma crosstalk , and was marketed as providing pictures superior to those of VHS.

However, the sticking point for both consumers and potential licensing partners of Betamax was the total recording time.

Very high-end Betamax machines still supported recording in the Beta I mode and some in an even higher resolution Beta Is Beta I Super HiBand mode, but at a maximum single-cassette run time of [with an L cassette].

Because Betamax was released more than a year before VHS, it held an early lead in the format war. However, by , United States' Betamax sales had dipped to only percent of all sales.

Some, including Sony's founder Akio Morita, say that it was due to Sony's licensing strategy with other manufacturers, which consistently kept the overall cost for a unit higher than a VHS unit, and that JVC allowed other manufacturers to produce VHS units license-free, thereby keeping costs lower.

The video cassette recorder was a mainstay in television -equipped American and European living rooms for more than twenty years from its introduction in The home television recording market, as well as the camcorder market, has since transitioned to digital recording on solid-state memory cards.

Though In the mids, several retail chains in the United States and Europe announced they would stop selling VHS equipment. The last known company in the world to manufacture VHS equipment was Funai of Japan, who produced video cassette recorders under the Sanyo brand in China and North America.

Funai ceased production of VHS equipment in July , citing falling sales and a shortage of components.

Despite the decline in both VHS players and programming on VHS machines, they are still owned in some households worldwide. Those who still use or hold on to VHS do so for a number of reasons, including nostalgic value, ease of use in recording, keeping personal videos or home movies , watching content currently exclusive to VHS, and collecting.

Some expatriate communities in the United States also obtain video content from their native countries in VHS format.

Although VHS has been discontinued in the United States, VHS recorders and blank tapes were still sold at stores in other developed countries prior to digital television transitions.

A market for pre-recorded VHS tapes has continued, and some online retailers such as Amazon still sell new and used pre-recorded VHS cassettes of movies and television programs.

None of the major Hollywood studios generally issue releases on VHS, the last major studio film to be released in the format in the United States, other than as part of special marketing promotions, was A History of Violence in However, there have been a few exceptions.

For example, The House of the Devil was released on VHS in as an Amazon-exclusive deal, in keeping with the film's intent to mimic s horror films.

Though occasionally showing compression artifacts and color banding that are common discrepancies in digital media, the durability and longevity of a VCD depends on the production quality of the disc, and its handling.

The data stored digitally on a VCD theoretically does not degrade in the analog sense like tape. In the disc player, there is no physical contact made with either the data or label sides.

When handled properly, a VCD will last a long time. Since a VCD can hold only 74 minutes of video, a movie exceeding that mark has to be divided into two or more discs.

Despite DVD's better quality typical horizontal resolution of versus lines per picture height , and the availability of standalone DVD recorders, VHS is still used in home recording of video content.

The commercial success of DVD recording and re-writing has been hindered by a number of factors including:.

High-capacity digital recording systems are also gaining in popularity with home users. These types of systems come in several form factors:.

These types of systems provide users with a no-maintenance solution for capturing video content. Customers of subscriber-based TV generally receive electronic program guides, enabling one-touch setup of a recording schedule.

Hard disk—based systems allow for many hours of recording without user-maintenance. Often considered an important medium of film history, the influence of VHS on art and cinema was highlighted in a retrospective staged at the Museum of Arts and Design in The documentary film Rewind This!

Vhs Kassette - Das ist bei der Digitalisierung von VHS-Kassetten wichtig

Die von den Köpfen geschriebenen Videospuren liegen dicht an dicht. Die Kassetten können bei den meisten als Leerkassetten verkauften Fabrikaten durch Herausbrechen einer Lasche auf der rückwärtigen Längsseite vor dem Löschen der enthaltenen Aufnahmen geschützt werden. Das Vorgehen in Eigenregie hat aber auch kritische Punkte — ein Aspekt: die zeitaufwendige Nachbearbeitung.
