64-398: Lolita Anime ( ロリータアニメ , Rorita Anime ) is a collection of adult original video animations (OVA) produced by Wonder Kids. It contains many notable firsts, as the first erotic original video animation , depicting hentai scenes which include yuri , BDSM and lolicon characters. It ran from February 1984 to May 1985 and consisted of six episodes. An alternative name for this anime

128-570: A 2004 news release (for their new OVAs aimed at women) that about 50% of the customers who had bought their anime DVDs in the past fell into the category of 25 to 40-year-old men, with only 13% of purchasers women, even with all ages included. (However, these statistics cover Bandai Visual anime DVDs in general.) Nikkei Business Publications also said in a news-release that mainly 25 to 40-year-old adults bought anime DVDs. Few OVAs target female audiences. Some OVAs based on television series (and especially those based on manga ) may provide closure to

192-663: A TV set with a VHS mechanism, were also once available for purchase. Combo units containing both a VHS mechanism and a DVD player were introduced in the late 1990s, and at least one combo unit, the Panasonic DMP-BD70V, included a Blu-ray player. VHS has been standardized in IEC 60774–1. The VHS cassette is a 187  mm wide, 103 mm deep, and 25 mm thick (7 3 ⁄ 8 × 4 1 ⁄ 16 × 1 inch) plastic shell held together with five Phillips-head screws . The flip-up cover, which allows players and recorders to access

256-557: A disadvantage. Matsushita's backing of JVC persuaded Hitachi , Mitsubishi , and Sharp to back the VHS standard as well. Sony's release of its Betamax unit to the Japanese market in 1975 placed further pressure on the MITI to side with the company. However, the collaboration of JVC and its partners was much stronger, which eventually led the MITI to drop its push for an industry standard. JVC released

320-553: A few minutes to two hours or more. An episode length of 30 minutes is common, but no standard length exists. An OVA series can run anywhere from a single episode to dozens of episodes in length. Many anime series first appeared as OVAs, and later grow to become television series or movies. Producers sometimes make other OVA releases as sequels, side stories, music-video collections, or bonus episodes that continue existing as television series or films. Much OVA-production aims at an audience of male anime enthusiasts. Bandai Visual said in

384-427: A flying erase head for erasing individual video fields, and one was a dummy used for balancing the head drum. The high tape-to-head speed created by the rotating head results in a far higher bandwidth than could be practically achieved with a stationary head. VHS machines record up to 3  MHz of baseband video bandwidth and 300 kHz of baseband chroma bandwidth. The luminance (black and white) portion of

448-586: A functional prototype of the Betamax format, and was very close to releasing a finished product. With this prototype, Sony persuaded the MITI to adopt Betamax as the standard, and allow it to license the technology to other companies. JVC believed that an open standard , with the format shared among competitors without licensing the technology, was better for the consumer. To prevent the MITI from adopting Betamax, JVC worked to convince other companies, in particular Matsushita (Japan's largest electronics manufacturer at

512-555: A maximum of about 430 m (1,410 ft) of tape at the lowest acceptable tape thickness, giving a maximum playing time of about four hours in a T-240/DF480 for NTSC and five hours in an E-300 for PAL at "standard play" (SP) quality. More frequently, however, VHS tapes are thicker than the required minimum to avoid complications such as jams or tears in the tape. Other speeds include "long play" (LP), "extended play" (EP) or "super long play" (SLP) (standard on NTSC; rarely found on PAL machines ). For NTSC, LP and EP/SLP double and triple

576-447: A necessity. The earliest known attempt to release an OVA was The Green Cat in 1983, although it cannot count as the first OVA: there is no evidence that the VHS tape became available immediately and the series remained incomplete. The first OVA to be billed as such was 1983's Dallos , released by Bandai . Other companies were quick to pick up on the idea, and the mid-to-late 1980s saw

640-405: A number of other competing tape standards. The cassettes themselves use a 0.5-inch magnetic tape between two spools and typically offer a capacity of at least two hours. The popularity of VHS was intertwined with the rise of the video rental market, with films being released on pre-recorded videotapes for home viewing. Newer improved tape formats such as S-VHS were later developed, as well as

704-414: A result, Wonder Kids decided to end Lolita Anime series. Much of Wonder Kids' staff was either uncredited or used pseudonyms. Known names include: Lolita Anime received mostly negative reception outside of otaku circles, with The Anime Encyclopedia entry on the work describing it as "disturbing" for its contents, which include gang rape and bondage of fictional underage girls. It is also known as

768-486: A second VCR. The first version of Macrovision introduces high signal levels during the vertical blanking interval , which occurs between the video fields. These high levels confuse the automatic gain control circuit in most VHS VCRs, leading to varying brightness levels in an output video, but are ignored by the TV as they are out of the frame-display period. "Level II" Macrovision uses a process called "colorstriping", which inverts

832-447: Is Wonder Magazine Series and was based on a manga by Fumio Nakajima, which was serialized in the lolicon magazine Lemon People . Lolita Anime was planned and produced during the height of the "lolicon boom" in amateur Japanese animation, which was pioneered by figures such as Aki Uchiyama (whose name would be used to promote Lolita Anime by Nikkatsu , released later the same year) and Hideo Azuma . The script and designs of

896-559: Is 3.335  cm / s (1.313 ips) for NTSC , 2.339 cm/s (0.921 ips) for PAL —or just over 2.0 and 1.4 metres (6 ft 6.7 in and 4 ft 7.2 in) per minute respectively. The tape length for a T-120 VHS cassette is 247.5 metres (812 ft). As with almost all cassette-based videotape systems, VHS machines pull the tape out of the cassette shell and wrap it around the inclined head drum, which rotates at 1,800 rpm in NTSC machines and at 1,500  rpm for PAL , one complete rotation of

Over 220 commercial duplication facilities around the world are equipped to supply Macrovision videocassette copy protection to rights owners...The study found that over 30% of VCR households admit to having unauthorized copies, and that the total annual revenue loss due to copying

1024-450: Is estimated at $ 370,000,000 annually. The system was first used in copyrighted movies beginning with the 1984 film The Cotton Club . Macrovision copy protection saw refinement throughout its years, but has always worked by essentially introducing deliberate errors into a protected VHS tape's output video stream. These errors in the output video stream are ignored by most televisions, but will interfere with re-recording of programming by

1088-419: Is extended/super long play ( 1 ⁄ 3 speed) which was primarily released into the NTSC market. 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. Despite generation loss in quality when a tape was copied, this practice

1152-422: Is magnified by the narrower tracks. The heads for linear audio are not on the spinning drum, so for them, the tape speed from one reel to the other is the same as the speed of the heads across the tape. This speed is quite slow: for SP it is about 2/3s that of an audio cassette, and for EP it is slower than the slowest microcassette speed. This is widely considered inadequate for anything but basic voice playback, and

1216-465: The NTSC television standard were able to record one hour of programming at their standard tape speed of 1.5  inches per second  (ips). The first VHS machines could record for two hours, due to both a slightly slower tape speed (1.31 ips) and significantly longer tape. Betamax's smaller cassette limited the size of the reel of tape, and could not compete with VHS's two-hour capability by extending

1280-450: The omega transport system) in a helical fashion, assisted by the slanted tape guides. The head rotates constantly at 1798.2 rpm in NTSC machines, exactly 1500 in PAL, each complete rotation corresponding to one frame of video. Two tape heads are mounted on the cylindrical surface of the drum, 180 degrees apart from each other, so that the two heads "take turns" in recording. The rotation of

In the 1970s, videotape technology became affordable for home use, and widespread adoption of videocassette recorders (VCRs) began; the VHS became the most popular media format for VCRs as it would win the "format war" against Betamax (backed by Sony ) and

1408-526: The 2000s. In 1956, after several attempts by other companies, the first commercially successful VTR, the Ampex VRX-1000 , was introduced by Ampex Corporation . At a price of US$ 50,000 in 1956 (equivalent to $ 560,343 in 2023) and US$ 300 (equivalent to $ 3,362 in 2023) for a 90-minute reel of tape, it was intended only for the professional market. Kenjiro Takayanagi , a television broadcasting pioneer then working for JVC as its vice president, saw

1472-524: The DVD release of the series. VHS The VHS ( Video Home System ) is a standard for consumer-level analog video recording on tape cassettes , introduced in 1976 by the Victor Company of Japan (JVC) . It was the dominant home video format throughout the tape media period in the late 1970s, 1980s, 1990s and early 2000s. Magnetic tape video recording was adopted by the television industry in

1536-843: The HR-3300EK in the United Kingdom. The United States received its first VHS-based VCR, the RCA VBT200, on August 23, 1977. The RCA unit was designed by Matsushita and was the first VHS-based VCR manufactured by a company other than JVC. It was also capable of recording four hours in LP (long play) mode. The UK received its first VHS-based VCR, the Victor HR-3300EK, in 1978. Quasar and General Electric followed-up with VHS-based VCRs – all designed by Matsushita. By 1999, Matsushita alone produced just over half of all Japanese VCRs. TV/VCR combos , combining

1600-520: The U-matic format. In 1971, JVC engineers Yuma Shiraishi and Shizuo Takano put together a team to develop a VTR for consumers. By the end of 1971, they created an internal diagram, "VHS Development Matrix", which established twelve objectives for JVC's new VTR: In early 1972, the commercial video recording industry in Japan took a financial hit. JVC cut its budgets and restructured its video division, shelving

1664-483: The VHS project. However, despite the lack of funding, Takano and Shiraishi continued to work on the project in secret. By 1973, the two engineers had produced a functional prototype. 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. Later, Sony had

These protection methods worked well to defeat analog-to-analog copying by VCRs of the time. Consumer products capable of digital video recording are mandated by law to include features which detect Macrovision encoding of input analog streams, and disrupt copying of

1792-454: The bandwidth to over 5 megahertz, yielding 420 analog horizontal (560 pixels left-to-right). Most Super VHS recorders can play back standard VHS tapes, but not vice versa. S-VHS was designed for higher resolution, but failed to gain popularity outside Japan because of the high costs of the machines and tapes. Because of the limited user base, Super VHS was never picked up to any significant degree by manufacturers of pre-recorded tapes, although it

1856-409: The cassette through the circular hole in the center of the underside, and two photodiodes are on the left and right sides of where the tape exits the cassette. When the clear tape reaches one of these, enough light will pass through the tape to the photodiode to trigger the stop function; some VCRs automatically rewind the tape when the trailing end is detected. Early VCRs used an incandescent bulb as

1920-399: The drum moving across the tape at (a writing speed of) 4.86 or 6.096 meters per second. To maximize the use of the tape, the video tracks are recorded very close together. To reduce crosstalk between adjacent tracks on playback, an azimuth recording method is used: The gaps of the two heads are not aligned exactly with the track path. Instead, one head is angled at plus six degrees from

1984-576: The earliest optical disc format, LaserDisc ; the lack of global adoption of these formats increased VHS's lifetime, which eventually peaked and started to decline in the late 1990s after the introduction of DVD , a digital optical disc format. VHS rentals were surpassed by DVD in the United States in 2003, which eventually became the preferred low-end method of movie distribution. For home recording purposes, VHS and VCRs were surpassed by (typically hard disk –based) digital video recorders (DVR) in

2048-456: The edge label. The tapes are made, pre-recorded, and inserted into the cassettes in cleanrooms , to ensure quality and to keep dust from getting embedded in the tape and interfering with recording (both of which could cause signal dropouts) There is a clear tape leader at both ends of the tape to provide an optical auto-stop for the VCR transport mechanism. In the VCR, a light source is inserted into

2112-415: The first VHS machines in Japan in late 1976, and in the United States in mid-1977. Sony's Betamax competed with VHS throughout the late 1970s and into the 1980s (see Videotape format war ). Betamax's major advantages were its smaller cassette size, theoretical higher video quality, and earlier availability, but its shorter recording time proved to be a major shortcoming. Originally, Beta I machines using

2176-409: The first erotic anime video release. It also featured the reoccurring character Miu, whose popularity prefigured that of Cream Lemon ' s Ami. Original video animation Like anime made for television broadcast, OVAs are divided into episodes. OVA media (tapes, laserdiscs or DVDs) usually contain just one episode each. Episode length varies from title to title: each episode may run from

2240-570: The first two episodes were based on Fumio Nakajima's manga. Sales for these first two episodes were not ideal, which led Wonder Kids to create Miu, a heroine who was more cartoony in appearance and subject to less sadistic treatment than the girls in prior episodes. A third installment by Nakajima was produced, but delayed in favour of Miu's debut episode. The installment was later added to the sixth and final episode. Not long after Lolita Anime ' s initial episodes were released, more erotic OVAs went into production from other independent animators; as

2304-419: The following steps, in this order: The erase head is fed by a high-level, high-frequency AC signal that overwrites any previous recording on the tape. Without this step, the new recording cannot be guaranteed to completely replace any old recording that might have been on the tape. The tape path then carries the tape around the spinning video-head drum, wrapping it around a little more than 180 degrees (called

2368-414: The head corresponding to one video frame. VHS uses an "M-loading" system, also known as M-lacing, where the tape is drawn out by two threading posts and wrapped around more than 180 degrees of the head drum (and also other tape transport components) in a shape roughly approximating the letter M . The heads in the rotating drum get their signal wirelessly using a rotary transformer . A VHS cassette holds

2432-409: 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. This is referred to as helical scan recording. A tape speed of 1 + 5 ⁄ 16 inches per second corresponds to the heads on

2496-446: The light source: when the bulb failed, the VCR would act as if a tape were present when the machine was empty, or would detect the blown bulb and completely stop functioning. Later designs use an infrared LED , which has a much longer life. The recording medium is a Mylar magnetic tape , 12.7 mm ( 1 ⁄ 2 inch) wide, coated with metal oxide , and wound on two spools .

The effort produced the U-matic format in 1971, which was the first cassette format to become a unified standard for different companies. It was preceded by the reel-to-reel 1 ⁄ 2 " EIAJ format. The U-matic format was successful in businesses and some broadcast television applications, such as electronic news-gathering, and

2624-438: The market flooded with OVAs. During this time, most OVA series were new, stand-alone titles. During Japan's economic bubble , production companies were more than willing to spontaneously decide to make a one- or two-part OVA in the 1980s. They paid money to anime studios, who then haphazardly created an OVA to be released to rental shops. Judging from sales, should a longer series be deemed feasible, TV networks paid for most of

2688-414: The miniaturized drum required twice as many heads to complete any given task. This almost always meant four heads on the miniaturized drum with performance similar to a two head VCR with a full sized drum. No attempt was made to record Hi-Fi audio with such devices, as this would require an additional four heads to work. W-VHS decks could have up to 12 heads in the head drum, of which 11 were active including

2752-447: The need for his company to produce VTRs for the Japanese market at a more affordable price. In 1959, JVC developed a two-head video tape recorder and, by 1960, a color version for professional broadcasting. In 1964, JVC released the DV220, which would be the company's standard VTR until the mid-1970s. In 1969, JVC collaborated with Sony Corporation and Matsushita Electric (Matsushita was

2816-470: The playing time for an E-XXX tape in an NTSC machine, this formula is used: Since the recording/playback time for PAL/SECAM is roughly 1/3 longer than the recording/playback time for NTSC, some tape manufacturers label their cassettes with both T-XXX and E-XXX marks, like T60/E90, T90/E120 and T120/E180. SP is standard play, LP is long play ( 1 ⁄ 2 speed, equal to recording time in DVHS "HS" mode), EP/SLP

2880-419: The playing time for any given cassette will vary between the systems. To avoid confusion, manufacturers indicate the playing time in minutes that can be expected for the market the tape is sold in: E-XXX indicates playing time in minutes for PAL or SECAM. T-XXX indicates playing time in minutes for NTSC or PAL-M. To calculate the playing time for a T-XXX tape in a PAL machine, this formula is used: To calculate

2944-572: The plot – closure not present in the original series. OVAs originated during the early 1980s. As the VCR became a fixture in Japanese homes, the anime industry grew. Demand for anime became massive, so much so that consumers would go to video stores to buy new animation outright. While people in the United States used the phrase " direct-to-video " as a pejorative for works that could not make it onto television or movie screens, in Japan direct-to-video became

3008-553: The production costs of the entire series. As the Japanese economy worsened in the 1990s , the flood of new OVA titles diminished to a trickle. Production of OVAs continued, but in smaller numbers. Many anime TV series ran 13 episodes rather than the traditional 26-episodes per season. Studios often designed new titles to be released to TV if they approached these lengths. In addition, the rising popularity of cable and satellite TV networks (with their typically less strict censorship) allowed

3072-431: The public to see direct broadcasts of many new titles. Therefore, many violent and risque series became regular TV series, when previously those titles would have been OVAs. During this time, most OVA content was limited to that related to existing and established titles. In 2000 and later, a new OVA trend began. Producers released many TV series without normal broadcasts of all of the episodes—but releasing some episodes on

3136-526: The quality of the SP speed, and dramatically lowered the quality of freeze frame and high speed search. Later models implemented both wide and narrow heads, and could use all four during pause and shuttle modes to further improve quality although machines later combined both pairs into one. In machines supporting VHS HiFi (described later), yet another pair of heads was added to handle the VHS HiFi signal. Camcorders using

3200-612: The recording time accordingly, but these speed reductions cause a reduction in horizontal resolution – from the normal equivalent of 250 vertical lines in SP, to the equivalent of 230 in LP and even less in EP/SLP. Due to the nature of recording diagonally from a spinning drum, the actual write speed of the video heads does not get slower when the tape speed is reduced. Instead, the video tracks become narrower and are packed closer together. This results in noisier playback that can be more difficult to track correctly: The effect of subtle misalignment

3264-509: The respective analog TV standard (625 for PAL or 525 for NTSC ; somewhat fewer scan lines are actually visible due to overscan and the VBI ). In modern-day digital terminology, NTSC VHS resolution is roughly equivalent to 333×480 pixels for luma and 40×480 pixels for chroma. 333×480=159,840 pixels or 0.16 MP (1/6 of a megapixel). PAL VHS resolution is roughly 333×576 pixels for luma and 40×576 pixels for chroma (although when decoded PAL and SECAM half

3328-449: The second tape head, is another 1 ⁄ 60 or 1 ⁄ 50 of a second TV picture field, and so on. Thus one complete head rotation records an entire NTSC or PAL frame of two fields. The original VHS specification had only two video heads. When the EP recording speed was introduced, the thickness of these heads was reduced to accommodate the narrower tracks. However, this subtly reduced

3392-517: The tape length. Instead, Sony had to slow the tape down to 0.787 ips (Beta II) in order to achieve two hours of recording in the same cassette size. Sony eventually created a Beta III speed of 0.524 ips, which allowed NTSC Betamax to break the two-hour limit, but by then VHS had already won the format battle. Additionally, VHS had a "far less complex tape transport mechanism" than Betamax, and VHS machines were faster at rewinding and fast-forwarding than their Sony counterparts. VHS eventually won

3456-441: The tape, has a latch on the right side, with a push-in toggle to release it (bottom view image). The cassette has an anti-despooling mechanism, consisting of several plastic parts between the spools, near the front of the cassette (white and black in the top view). The spool latches are released by a push-in lever within a 6.35 mm ( 1 ⁄ 4 inch) hole at the bottom of the cassette, 19 mm ( 3 ⁄ 4 inch) in from

3520-611: The time, marketing its products under the National brand in most territories and the Panasonic brand in North America, and JVC's majority stockholder), to accept VHS, and thereby work against Sony and the MITI. Matsushita agreed, primarily out of concern that Sony might become the leader in the field if its proprietary Betamax format was the only one allowed to be manufactured. Matsushita also regarded Betamax's one-hour recording time limit as

3584-409: The track, and the other at minus six degrees. This results, during playback, in destructive interference of the signal from the tracks on either side of the one being played. Each of the diagonal-angled tracks is a complete TV picture field , lasting 1 ⁄ 60 of a second ( 1 ⁄ 50 on PAL) on the display. One tape head records an entire picture field. The adjacent track, recorded by

3648-444: The vertical color resolution). JVC countered 1985's SuperBeta with VHS HQ, or High Quality. 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 effect

3712-404: The video is frequency modulated and combined with a down-converted " color under " chroma (color) signal that is encoded using quadrature amplitude modulation . Including side bands , the signal on a VHS tape can use up to 10 MHz of RF bandwidth. VHS horizontal resolution is 240 TVL , or about 320 lines across a scan line. The vertical resolution (number of scan lines) is the same as

3776-411: The video. Both intentional and false-positive detection of Macrovision protection has frustrated archivists who wish to copy now-fragile VHS tapes to a digital format for preservation. As of the 2020s, modern software decoding ignores Macrovison as software is not limited to the fixed standards that Macrovision was intended to disrupt in hardware based systems. The recording process in VHS consists of

3840-718: The war, gaining 60% of the North American market by 1980. 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. JVC started selling the HR-3300 in Akihabara , Tokyo, Japan, on October 31, 1976. Region-specific versions of the JVC HR-3300 were also distributed later on, such as the HR-3300U in the United States, and

3904-509: Was a major liability for VHS-C camcorders that encouraged the use of the EP speed. Color depth deteriorates significantly at lower speeds in PAL: often, a color image on a PAL tape recorded at low speed is displayed only in monochrome, or with intermittent color, when playback is paused. VHS cassettes for NTSC and PAL/SECAM systems are physically identical, although the signals recorded on the tape are incompatible. The tape speeds are different too, so

Therefore, soon after the U-Matic release, all three companies started working on new consumer-grade video recording formats of their own. Sony started working on Betamax , Matsushita started working on VX , and JVC released the CR-6060 in 1975, based on

4032-523: Was regarded as a widespread problem, which members of the Motion Picture Association of America (MPAA) claimed caused them great financial losses. In response, several companies developed technologies to protect copyrighted VHS tapes from casual duplication by home users. The most popular method was Analog Protection System , better known simply as Macrovision , produced by a company of the same name. According to Macrovision: The technology

4096-528: Was to increase the apparent horizontal resolution of a VHS recording from 240 to 250 analog (equivalent to 333 pixels from left-to-right, in digital terminology). 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. In 1987, JVC introduced a new format called Super VHS (often known as S-VHS) which extended
