The home television recording market, as well as the camcorder market, has since transitioned to digital recording on solid-state memory cards. The frequency modulation of the VHS luminance signal is limited to 3 megahertz, which makes higher resolutions technically impossible even with the highest-quality recording heads and tape materials, but an HQ branded deck includes luminance noise reduction, chroma noise reduction, white clip extension, and improved sharpness circuitry. The magnetic tape on VHS-C cassettes is wound on one main spool and uses a gear wheel to advance the tape..
Feb 23, 2012 #6 bbmyers Tele-Meister For example, a 120 GB system recording at an extended recording rate (XP) of 10 Mbit/s MPEG-2 can record over 25 hours of video content. The rotation of the inclined head drum, combined with the relatively slow movement of the tape, results in each head recording a track oriented at a diagonal with respect to the length of the tape, with the heads moving across the tape at speeds higher than what would otherwise be possible. , Soon after, Sony and Matsushita broke away from the collaboration effort, in order to work on video recording formats of their own. Ultimately neither format "won" and both have been superseded by digital high definition equipment. Cinelerra 7.2 Original / GG v2020-10 / CV 2.3, K-Lite Codec Pack Standard 15.8.5 / Update 15.8.5.

The tape passes across the audio and control head, which records the control track and the linear audio track or tracks. For the VHS SP mode, which already uses a lower tape speed than the compact cassette, this resulted in a mediocre frequency response of roughly 100 Hz to 10 kHz for NTSC, frequency response for PAL VHS with its lower standard tape speed was somewhat worse. The major VHS OEMs resisted HQ due to cost concerns, eventually resulting in JVC reducing the requirements for the HQ brand to white clip extension plus one other improvement. Most Super VHS recorders can play back standard VHS tapes, but not vice versa. Developed by Victor Company of Japan (JVC) in the early 1970s, it was released in Japan on September 9, 1976, and in the United States on August 23, 1977. 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. For NTSC, LP and EP/SLP doubles and triples the recording time accordingly, but these speed reductions cause a reduction in horizontal resolution – from the normal equivalent of 250 vertical scan lines lines in SP, to the equivalent of 230 in LP and even less in EP/SLP. Similar systems were manufactured in the United States by Corvus and Alpha Microsystems, and in the UK by Backer from Danmere Ltd. VHS can record and play back all varieties of analog television signals in existence at the time VHS was devised. Disney ones selling for thousands of dollars, Here's How to Jailbreak iOS 14.1 Using Checkra1n, Check Out Devices That Can Use the Jailbreaking Tool. The corresponding numbers here for PAL are, on the other hand, exact, as PAL's field rate is exactly 1/50 of a second. S-VHS machines for the Brazilian market record in NTSC and convert between it and PAL-M. 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. For example, The House of the Devil was released on VHS in 2010 as an Amazon-exclusive deal, in keeping with the film's intent to mimic 1980s horror films. With this prototype, Sony persuaded the MITI to adopt Betamax as the standard, and allow it to license the technology to other companies. S-VHS was designed for higher resolution, but failed to gain popularity outside Japan because of the high costs of the machines and tapes. VHS tapes have approximately 3 MHz of video bandwidth and 400 kHz of chroma bandwidth, which is lower than the 6 MHz in NTSC broadcasts, and the 5 MHz in Type C videotape. VHS tapes stopped being produced in 2008, and Panasonic stopping selling VCRs in 2012. , The first VCR to use VHS was the Victor HR-3300, and was introduced by the president of JVC in Japan on September 9, 1976. However some rewinder brands did have some frequent abrupt stops, which occasionally led to tape damage. In 1987, JVC introduced a new format called Super VHS (often known as S-VHS) which extended the bandwidth to over 5 megahertz, yielding 420 analog horizontal (560 pixels left-to-right). The company began making VCRs in 1983, selling as many as 15 million units per year in its golden days. Sound cannot be recorded on a VHS tape without recording a video signal, even in the audio dubbing mode. "VHS: A Posthumanist Aesthetics of Recording and Distribution." . VCRs were the way to watch home movies that were sold and rented (remember Blockbuster?!). , As VHS was designed to facilitate recording from various sources, including television broadcasts or other VCR units, content producers quickly found that home users were able to use the devices to copy videos from one tape to another. The tape is wrapped around the head drum, using a little more than 180 degrees of the drum. This high quality compared to other consumer audio recording formats such as compact cassette attracted the attention of amateur and hobbyist recording artists. Retrieved on 2006-12-28 from, John Howells. One tape head records an entire picture field.
Linear stereo fits two independent channels in the same space as the original mono audiotrack. Misalignments may lead to imperfect joining of the signal, resulting in low-pitched buzzing. IEEE History Center: Development of VHS.  Other speeds include "long play" (LP), and "extended play" (EP) or "super long play" (SLP) (standard on NTSC; rarely found on PAL machines). As an acknowledgement of the continued use of VHS, Panasonic announced the world's first dual deck VHS-Blu-ray player in 2009.
Recorders must be capable of being produced in high volume, their parts must be interchangeable, and they must be easy to service.

JVC started selling the HR-3300 in Akihabara, Tokyo, Japan on October 31, 1976. U-matic was successful in business and some broadcast applications (such as electronic news-gathering), but due to cost and limited recording time very few of the machines were sold for home use. This means that the VCR — and subsequently, VHS tapes — are finally dead. - Transformers News - TFW2005", "DILIFE - The Slow Decline of the VHS Tapes", "An Armchair Revolution, and Barbie, Too VHS Film Retrospective at Museum of Arts and Design", "Yale Is Building an Incredible Collection of VHS Tapes", "Even Yale University is getting into VHS collecting", VHSCollector.com: Analog Video Cassette Archive, https://en.wikipedia.org/w/index.php?title=VHS&oldid=984951534, Articles needing additional references from November 2008, All articles needing additional references, Articles with unsourced statements from November 2019, Articles with unsourced statements from November 2015, Articles with unsourced statements from June 2018, Articles with unsourced statements from March 2014, Articles with unsourced statements from July 2014, Wikipedia articles in need of updating from April 2014, All Wikipedia articles in need of updating, Articles with limited geographic scope from July 2015, Articles with multiple maintenance issues, Articles with empty sections from March 2020, Creative Commons Attribution-ShareAlike License, common: 120, 160 minutes (Standard Play Mode); unusual: 5, 10, 15, 30, 60, 90, 130, 180, 190, 200, 210 minutes (Standard Play Mode). , In 1971, JVC engineers Yuma Shiraishi and Shizuo Takano put together a team to develop a consumer-based VTR.

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. , In 1974, the Japanese Ministry of International Trade and Industry (MITI), desiring to avoid consumer confusion, attempted to force the Japanese video industry to standardize on just one home video recording format. This is because some parameters of analog broadcast TV are not applicable to VHS recordings, the number of VHS tape recording format variations is smaller than the number of broadcast TV signal variations—for example, analog TVs and VHS machines (except multistandard devices) are not interchangeable between the UK and Germany, but VHS tapes are.
