76-598: Xvid is a primary competitor of the DivX Pro Codec. In contrast with the DivX codec, which is proprietary software developed by DivX, Inc. , Xvid is free software distributed under the terms of the GNU General Public License . This also means that unlike the DivX codec, which is only available for a limited number of platforms, Xvid can be used on all platforms and operating systems for which

152-655: A tongue-in-cheek reference to the DIVX system. Although not created by them, the DivX company adopted the name of the popular DivX ;-) codec. The company dropped the smiley and released DivX 4.0, which was actually the first DivX version to trademark the term DivX . DivX ;-) (not DivX) 3.11 Alpha and later 3.xx versions refers to a hacked version of the Microsoft MPEG-4 Version 3 video codec (not to be confused with MPEG-4 Part 3 ) from Windows Media Tools 4 codecs. The video codec, which

228-485: A DVD player, a figure that had surpassed VCRs; it was also higher than personal computers or cable television. The DVD specifications created and updated by the DVD Forum are published as so-called DVD Books (e.g. DVD-ROM Book, DVD-Audio Book, DVD-Video Book, DVD-R Book, DVD-RW Book, DVD-RAM Book, DVD-AR (Audio Recording) Book, DVD-VR (Video Recording) Book, etc.). DVD discs are made up of two discs; normally one

304-449: A November 1997 online interview, and clarified it would release discs in early 1998. However, this date would be pushed back several times before finally releasing their first titles at the 1999 Consumer Electronics Show . In 2001, blank DVD recordable discs cost the equivalent of $ 27.34 US dollars in 2022. Movie and home entertainment distributors adopted the DVD format to replace

380-523: A codec and a player by adding an optional media container format called "DivX Media Format" ("DMF") (with a .divx extension) that includes support for the following DVD-Video and VOB container like features. This media container format is used for the MPEG-4 Part 2 codec. This new DivX Media Format also came with a "DivX Ultra Certified" profile, and all "Ultra" certified players must support all DivX Media Format features. While video encoded with

456-634: A computer. DVD players are a particular type of devices that do not require a computer to work, and can read DVD-Video and DVD-Audio discs. Read and write speeds for the first DVD drives and players were 1,385  kB /s (1,353  KiB /s); this speed is usually called "1×". More recent models, at 18× or 20×, have 18 or 20 times that speed. For CD drives, 1× means 153.6 kB/s (150 KiB/s), about one-ninth as swift. DVDs can spin at much higher speeds than CDs – DVDs can spin at up to 32000 RPM vs 23000 for CDs. In practice, they are not spun by optical drives anywhere close to these speeds to provide

532-491: A cost: DVD±DLs have slower write speeds as compared to DVD±R. DVD-R DL was developed for the DVD Forum by Pioneer Corporation ; DVD+R DL was developed for the DVD+RW Alliance by Mitsubishi Kagaku Media (MKM) and Philips . Recordable DVD discs supporting dual-layer technology are backward-compatible with some hardware developed before the recordable medium. DVD drives are devices that can read DVD discs on

608-495: A double-sided disc. Philips and Sony decided that it was in their best interests to end the format war, and on September 15, 1995 agreed to unify with companies backing the Super Density Disc to release a single format, with technologies from both. After other compromises between MMCD and SD, the group of computer companies won the day, and a single format was agreed upon. The computer companies also collaborated with

684-773: A dual-layer DVD up to 8.5 GB. Variants can store up to a maximum of 17.08 GB. Prerecorded DVDs are mass-produced using molding machines that physically stamp data onto the DVD. Such discs are a form of DVD-ROM because data can only be read and not written or erased. Blank recordable DVD discs ( DVD-R and DVD+R ) can be recorded once using a DVD recorder and then function as a DVD-ROM. Rewritable DVDs ( DVD-RW , DVD+RW , and DVD-RAM ) can be recorded and erased many times. DVDs are used in DVD-Video consumer digital video format and less commonly in DVD-Audio consumer digital audio format, as well as for authoring DVD discs written in

760-541: A free Windows CLI through DivX Labs with documentation on the DivX Developer Portal; DivX describes the release as a reference mux to demonstrate DivX Plus MKV extensions like World Fonts and Smooth FF/RW . DivX, Inc. markets a certification program to consumer electronics and IC manufacturers for the purpose of guaranteed compatibility and playback of video files that fall within DivX profiles. Devices that have been DivX certified usually brandish one of

836-725: A large number of media players and decoders based on libavcodec (such as MPlayer , VLC , ffdshow or Perian ). As of 2016, xvid.com carries binaries for using the codec. However, early versions of the codec had a bug that prevented XviD-encoded files from being decoded with DivX, even when they were encoded using the DivX fourcc. Xvid encoded files can be written to a CD or DVD and played in some (but not all) DivX compatible DVD players and media players . However, Xvid can optionally encode video with advanced MPEG-4 features that most DivX Certified set-top players do not support. Files encoded with global motion compensation , Qpel , MPEG quantization , multiple B-frames or files that exceed

912-549: A new and improved version of the codec's encoding algorithm known as "encore2". This code was included in the OpenDivX public source repository for a brief time, but then was abruptly removed. The explanation from DivX at the time was that "the community really wants a Winamp , not a Linux ." It was at this point that the project forked . That summer, Rota left the French Riviera and moved to San Diego "with nothing but

988-485: A noticeable pause in A/V playback on earlier DVD players , the length of which varies between hardware. A printed message explaining that the layer-transition pause was not a malfunction became standard on DVD keep cases . During mastering, a studio could make the transition less obvious by timing it to occur just before a camera angle change or other abrupt shift, an early example being the DVD release of Toy Story . Later in

1064-524: A pack of cigarettes" where he and Greenhall founded what would eventually become DivX, Inc. DivX took the encore2 code and developed it into DivX 4.0, initially released in July 2001. Other developers who had participated in OpenDivX took encore2 and started a new project— Xvid —that started with the same encoding core. DivX, Inc. has since continued to develop the DivX codec, releasing DivX 5.0 in March 2002. By

1140-479: A press release stating that they would only accept a single format. The group voted to boycott both formats unless the two camps agreed on a single, converged standard. They recruited Lou Gerstner , president of IBM, to pressure the executives of the warring factions. In one significant compromise, the MMCD and SD groups agreed to adopt proposal SD 9, which specified that both layers of the dual-layered disc be read from

1216-449: A safety margin. DVD drives limit reading speed to 16× (constant angular velocity), which means 9280 rotations per minute. Early-generation drives released before the mid-2000s have lower limits. DVD recordable and rewritable discs can be read and written using either constant angular velocity (CAV), constant linear velocity (CLV), Partial constant angular velocity (P-CAV) or Zoned Constant Linear Velocity (Z-CLV or ZCLV). Due to

1292-420: A special AVCHD format to hold high definition material (often in conjunction with AVCHD format camcorders ). DVDs containing other types of information may be referred to as DVD data discs. The Oxford English Dictionary comments that, "In 1995, rival manufacturers of the product initially named digital video disc agreed that, in order to emphasize the flexibility of the format for multimedia applications,

1368-555: A standard definition CRT TV or an HD flat panel TV with a DVD mechanism under the CRT or on the back of the flat panel, and VCR/DVD combos were also available for purchase. For consumers, DVD soon replaced VHS as the favored choice for home movie releases. In 2001, DVD players outsold VCRs for the first time in the United States. At that time, one in four American households owned a DVD player. By 2007, about 80% of Americans owned

1444-432: A storage capacity of 4.7 GB (4.38 GiB ) for a single-layered, single-sided disc and 8.5 GB (7.92 GiB) for a dual-layered, single-sided disc. The DVD specification ended up similar to Toshiba and Matsushita's Super Density Disc, except for the dual-layer option. MMCD was single-sided and optionally dual-layer, whereas SD was two half-thickness, single-layer discs which were pressed separately and then glued together to form

1520-424: Is DivX's version of digital rights management (DRM), which allows content copyright holders to control distribution. In 2009, DivX, Inc. received format approval from major Hollywood studios including Sony, Paramount, and Lionsgate, which has allowed content retailers to sell protected videos that will play on current and previous generations of DivX certified devices. The terms of the contract are not known, so it

1596-419: Is available in two formats, General (650 nm) and Authoring (635 nm), where Authoring discs may be recorded with CSS encrypted video content but General discs may not. Dual-layer recording (occasionally called double-layer recording) allows DVD-R and DVD+R discs to store nearly double the data of a single-layer disc—8.5 and 4.7 gigabyte capacities, respectively. The additional capacity comes at

1672-462: Is blank, and the other contains data. Each disc is 0.6 mm thick, and are glued together to form a DVD disc. The gluing process must be done carefully to make the disc as flat as possible to avoid both birefringence and "disc tilt", which is when the disc is not perfectly flat, preventing it from being read. Some specifications for mechanical, physical and optical characteristics of DVD optical discs can be downloaded as freely available standards from

1748-450: Is lost. Numerous factors affect longevity: composition and quality of the media (recording and substrate layers), humidity and light storage conditions, the quality of the initial recording (which is sometimes a matter of mutual compatibility of media and recorder), etc. According to NIST , "[a] temperature of 64.4 °F (18 °C) and 40% RH [Relative Humidity] would be considered suitable for long-term storage. A lower temperature and RH

1824-496: Is measureable, which means that future data losses caused by deteriorating media can be predicted well in advance by measuring the rate of correctable data errors. Support of measuring the disc quality varies among optical drive vendors and models. DVD-Video is a standard for distributing video/audio content on DVD media. The format went on sale in Japan on November 1, 1996, in the United States on March 24, 1997, to line up with

1900-583: Is recommended for extended-term storage." As with CDs, the information and data storage will begin to degrade over time with most standard DVDs lasting up to 30 years depending on the type of environment they are stored and whether they are full with data. According to the Optical Storage Technology Association (OSTA), "Manufacturers claim lifespans ranging from 30 to 100 years for DVD, DVD-R and DVD+R discs and up to 30 years for DVD-RW, DVD+RW and DVD-RAM." According to

1976-483: Is the explanation provided in a DVD Forum Primer from 2000 and in the DVD Forum 's mission statement, which the purpose is to promote broad acceptance of DVD products on technology, across entertainment, and other industries. Because DVDs became highly popular for the distribution of movies in the 2000s, the term DVD became popularly used in English as a noun to describe specifically a full-length movie released on

2052-440: Is unknown if that approval is still in effect. Dr. DivX OSS is capable of transcoding many video formats to DivX-encoded video. The original closed-source Dr. DivX terminated at version 1.06 for DivX 5.21. That was the last version of DivX capable of running on Windows 9x . An open-source version has since been made, which supports DivX 6. Dr. DivX offers greatly expanded features over the free DivX Converter application, that

2128-676: Is used with no explicit geographical restriction. The last US patents expired in November 2023. The only patents left worldwide are in Brazil. The Fedora Project , a community backed by Red Hat , has imported xvidcore to its repositories on January 24, 2023. In July 2002, Sigma Designs released an MPEG-4 video codec called the REALmagic MPEG-4 Video Codec. Before long, people testing this new codec found that it contained considerable portions of Xvid code. Sigma Designs

2204-505: The 69th Academy Awards that day; in Canada, Central America, and Indonesia later in 1997; and in Europe, Australia, and Africa in 1998. DVD-Video became the dominant form of home video distribution in Japan when it first went on sale on November 1, 1996, but it shared the market for home video distribution in the United States for several years; it was June 15, 2003, when weekly DVD-Video in

2280-508: The High Efficiency Video Coding DivX HEVC Ultra HD codec. The most recent version of the codec itself is version 6.9.2, which is several years old. New version numbers on the packages now reflect updates to the media player, converter, etc. The "DivX" brand is distinct from " DIVX ", which is an obsolete video rental system. The winking emoticon in the early " DivX ;-) " codec name was

2356-562: The ISO website. There are also equivalent European Computer Manufacturers Association (Ecma) standards for some of these specifications, such as Ecma-267 for DVD-ROMs. Also, the DVD+RW Alliance publishes competing recordable DVD specifications such as DVD+R, DVD+R DL, DVD+RW or DVD+RW DL . These DVD formats are also ISO standards. Some DVD specifications (e.g. for DVD-Video) are not publicly available and can be obtained only from

2432-612: The Optical Storage Technology Association (OSTA) on the use of their implementation of the ISO-13346 file system (known as Universal Disk Format ) for use on the new DVDs. The format's details were finalized on December 8, 1995. In November 1995, Samsung announced it would start mass-producing DVDs by September 1996. The format launched on November 1, 1996, in Japan, mostly with music video releases. The first major releases from Warner Home Video arrived on December 20, 1996, with four titles being available. The format's release in

2508-551: The Video buffering verifier limitations may not play back properly on DivX Certified hardware devices. For example, Xvid specifies three warp points for its implementation of global motion compensation as opposed to the single warp point implementation of DivX. Enabling some of the more advanced encoding features can compromise player compatibility. Some issues exist with the custom quantization matrices used in tools such as AutoGK that automate encoding with Xvid. This can (depending on

2584-521: The format war of 2006–2008 . A dual layer HD DVD can store up to 30 GB and a dual layer Blu-ray disc can hold up to 50 GB. However, unlike previous format changes, e.g., vinyl to Compact Disc or VHS videotape to DVD, initially there was no immediate indication that production of the standard DVD will gradually wind down, as at the beginning of the 2010s they still dominated, with around 75% of video sales and approximately one billion DVD player sales worldwide as of April 2011. In fact, experts claimed that

2660-636: The AVI file format. The methods of including multiple audio and even subtitle tracks involve storing the data in RIFF headers and other such AVI hacks which have been known for quite a while, such that even VirtualDubMod supports them. DivX, Inc. did this on purpose to keep at least partial backward compatibility with AVI, so that players that do not support the new features available to the .divx container format (like interactive menus, chapter points and XSUB subtitles) can at least play that primary video stream (usually

2736-465: The DVD Book assigns them distinct disc types. DVD-14 has no analogous 8 cm type. The comparative data for 8 cm discs is provided further down. HP initially developed recordable DVD media from the need to store data for backup and transport. DVD recordables are now also used for consumer audio and video recording. Three formats were developed: DVD-R / RW , DVD+R / RW (plus), and DVD-RAM . DVD-R

2812-671: The DVD Format/Logo Licensing Corporation (DVD FLLC) for a fee of US$ 5000. Every subscriber must sign a non-disclosure agreement as certain information on the DVD Books is proprietary and confidential. Borrowing from the LaserDisc format, the DVD standard includes DVD-10 discs (Type B in ISO) with two recorded data layers such that only one layer is accessible from either side of the disc. This doubles

2888-500: The DVD would remain the dominant medium for at least another five years as Blu-ray technology was still in its introductory phase, write and read speeds being poor and necessary hardware being expensive and not readily available. Consumers initially were also slow to adopt Blu-ray due to the cost. By 2009, 85% of stores were selling Blu-ray Discs. A high-definition television and appropriate connection cables are also required to take advantage of Blu-ray disc. Some analysts suggested that

The output from DivX to Go's PlayStation 3 preset is also playable on the Xbox 360. DVD The DVD (common abbreviation for digital video disc or digital versatile disc ) is a digital optical disc data storage format. It

3040-475: The DivX codec is an MPEG-4 video stream, the DivX Media Format is analogous to media container formats such as Apple's QuickTime. In much the same way that media formats such as DVD specify MPEG-2 video as a part of their specification, the DivX Media Format specifies MPEG-4-compatible video as a part of its specification. However, despite the use of the ".divx" extension, this format is an extension to

3116-462: The U.S. was delayed multiple times, from August 1996, to October 1996, November 1996, before finally settling on early 1997. Players began to be produced domestically that winter, with March 24, 1997, as the U.S. launch date of the format proper in seven test markets. Approximately 32 titles were available on launch day, mainly from the Warner Bros. , MGM , and New Line libraries, with

3192-456: The United States rentals began outnumbering weekly VHS cassette rentals. DVD-Video is still the dominant form of home video distribution worldwide except for in Japan where it was surpassed by Blu-ray Disc when Blu-ray first went on sale in Japan on March 31, 2006. The purpose of CSS is twofold: In 2006, two new formats called HD DVD and Blu-ray Disc were released as the successor to DVD. HD DVD competed unsuccessfully with Blu-ray Disc in

3268-559: The biggest obstacle to replacing DVD was due to its installed base; a large majority of consumers were satisfied with DVDs. DVDs started to face competition from video on demand services around 2015. With increasing numbers of homes having high speed Internet connections, many people had the option to either rent or buy video from an online service, and view it by streaming it directly from that service's servers, meaning they no longer need any form of permanent storage media for video at all. By 2017, digital streaming services had overtaken

3344-489: The codec, which "took about a week". In early 2000, Jordan Greenhall recruited Rota to form a company (originally called DivXNetworks, Inc., renamed to DivX, Inc. in 2005) to develop an MPEG-4 codec, from scratch, that would still be backward-compatible with the Microsoft MPEG-4 Version 3 format. This effort resulted first in the release of the "OpenDivX" codec and source code on 15 January 2001. OpenDivX

However, most recent model DivX compatible DVD players have improved support for custom quantization matrices. DivX DivX is a brand of video codec products developed by DivX, LLC . There are three DivX codecs : the original MPEG-4 Part 2 DivX codec, the H.264/MPEG-4 AVC DivX Plus HD codec and

3496-481: The developers of the DVD format and eventually the first company to actually release a DVD-based console. Game consoles such as the PlayStation 2 , Xbox , and Xbox 360 use DVDs as their source medium for games and other software. Contemporary games for Windows were also distributed on DVD. Early DVDs were mastered using DLT tape, but using DVD-R DL or +R DL eventually became common. TV DVD combos , combining

3572-460: The following marks: DivX certified devices have included DVD players, car stereos, mobile phones, televisions, Blu-ray players, and even alarm clocks. Aside from verifying proper decoding of files conforming to the DivX profiles the certification also confirms the device can play back DivX Video on Demand content, which includes Hollywood content that can be purchased from Internet retailers. On 4 December 2007, native MPEG-4 ASP playback support

3648-892: The format's life, larger data buffers and faster optical pickups in DVD players made layer transitions effectively invisible regardless of mastering. Dual-layer DVDs are recorded using Opposite Track Path (OTP). The DVD Book also permits an additional disc type called DVD-14: a hybrid double-sided disc with one dual-layer side, one single-layer side, and a total nominal capacity of 12.3 GB. DVD-14 has no counterpart in ISO. Both of these additional disc types are extremely rare due to their complicated and expensive manufacturing. For this reason, some DVDs that were initially issued as double-sided discs were later pressed as two-disc sets. Note : The above sections regarding disc types pertain to 12 cm discs. The same disc types exist for 8 cm discs: ISO standards still regard these discs as Types A–D, while

3724-442: The format; for example the sentence to "watch a DVD" describes watching a movie on DVD. Released in 1987, CD Video used analog video encoding on optical discs matching the established standard 120 mm (4.7 in) size of audio CDs. Video CD (VCD) became one of the first formats for distributing digitally encoded films in this format, in 1993. In the same year, two new optical disc storage formats were being developed. One

3800-459: The ground up. By the beginning of the 2020s, sales of DVD had dropped 86% with respect to the peak of DVD sales around 2005, while on-demand sales and, overall, subscription streaming of TV shows and movies grew by over 1,200%. At its peak, DVD sales represented almost two thirds of video market in the US; approximately 15 years later, around 2020, they fell to only 10% of the market. By 2022, there

3876-487: The grouping is a specific subset of what is in the standards, there are certification processes for each of the profiles that device manufacturers must follow. All DivX certified devices bearing a DivX logo will adhere to one of the profiles outlined in the table below as would any tools that support the DivX profiles. 352×288×25 720×576×25 720×480×30, 720×576×25 5/6: 1920×1080×30, 1280×720×60 1280×720×60 NAL: 24000000 5/6: 244800 DivX Video on Demand (DivX VOD)

Soon after, DARC released a beta version of their closed-source commercial DivX 4 codec, which was based on encore2, saying that "what the community really wants is a Winamp , not a Linux ." It was after this that a fork of OpenDivX was created, using the latest version of encore2 that

Of course, the DivX codec and tools like Dr. DivX still support the traditional method of creating standard AVI files. Since version 5.0 of DivX, the FourCC (identifying code) for the DivX MPEG-4 Part 2 codec is DX50. Previously it used DIVX. DivX Plus HD is a marketing name for a file type using

4104-428: The notable inclusion of the 1996 film Twister . However, the launch was planned for the following day (March 25), leading to a distribution change with retailers and studios to prevent similar violations of breaking the street date . The nationwide rollout for the format happened on August 22, 1997. DTS announced in late 1997 that they would be coming onto the format. The sound system company revealed details in

4180-451: The original film recordings. Shows that were made between the early 1980s and the early 2000s were generally shot on film, then transferred to video tape, and then edited natively in either NTSC or PAL; this makes high-definition transfers impossible, as these SD standards were baked into the final cuts of the episodes. Star Trek: The Next Generation was the only such show that had a Blu-ray release, as prints were re-scanned and edited from

4256-399: The preferred abbreviation DVD would be understood to denote digital versatile disc." The OED also states that in 1995, "The companies said the official name of the format will simply be DVD. Toshiba had been using the name 'digital video disc', but that was switched to 'digital versatile disc' after computer companies complained that it left out their applications." "Digital versatile disc"

4332-459: The project's CVS . In early 2001, DARC member Sparky wrote an improved version of the encoding core called encore2. This was updated several times before, in April, it was removed from CVS without warning. The explanation given by Sparky was "We (our bosses) decided that we are not ready to have it in public yet." In July 2001, developers started complaining about a lack of activity in the project;

4408-518: The release of version 5.2.1 on 8 September 2004, the DivX codec was substantially feature-complete. Changes since then have tended to focus on speed, and encouraging wider hardware player support, while the company has also focused its time on the formats and next generation codecs. In February 2011, DivX was acquired by Rovi Corporation , upon completion of its acquisition of Sonic Solutions . In 2014, Blackstone Group and Parallax Capital acquired DivX from Rovi for $ 75 million. On January 5, 2015, it

4484-412: The sales of DVDs and Blu-rays for the first time. Until the end of the 2010s, manufacturers continued to release standard DVD titles as of 2020 , and the format remained the preferred one for the release of older television programs and films. Shows that were shot and edited entirely on film, such as Star Trek: The Original Series , could not be released in high definition without being re-scanned from

4560-414: The same side—instead of proposal SD 10, which would have created a two-sided disc that users would have to turn over. Philips/Sony strongly insisted on the source code, EFMPlus , that Kees Schouhamer Immink had designed for the MMCD, because it makes it possible to apply the existing CD servo technology. Its drawback was a loss from 5 to 4.7 Gbyte of capacity. As a result, the DVD specification provided

4636-663: The slightly lower data density of dual layer DVDs (4.25 GB instead of 4.7 GB per layer), the required rotation speed is around 10% faster for the same data rate, which means that the same angular speed rating equals a 10% higher physical angular rotation speed. For that reason, the increase of reading speeds of dual layer media has stagnated at 12× ( constant angular velocity ) for half-height optical drives released since around 2005, and slim type optical drives are only able to record dual layer media at 6× (constant angular velocity), while reading speeds of 8× are still supported by such. The quality and data integrity of optical media

4712-586: The source code can be compiled. In January 2001, DivXNetworks founded OpenDivX as part of Project Mayo which was intended to be a home for open source multimedia projects. OpenDivX was an open-source MPEG-4 video codec based on a stripped-down version of the MoMuSys reference MPEG-4 encoder. The source code, however, was placed under a restrictive license and only members of the DivX Advanced Research Centre (DARC) had write access to

4788-436: The standard Matroska media container format (.mkv), rather than the proprietary DivX Media Format. DivX Plus HD files contain an H.264 video bitstream, AAC surround sound audio, and a number of XML-based attachments defining chapters, subtitles and meta data. This media container format is used for the H.264/MPEG-4 AVC codec. DivX has defined profiles which are subsets of MPEG-4/AVI and H.264/Matroska standards. Because

4864-729: The terms of the GPL. After articles were published in Slashdot and The Inquirer , in August 2002 Sigma Designs agreed to publish their source code. Xvid is not a video format ; it is a program for compressing to and decompressing from (hence the name codec ) the MPEG-4 ASP format. Since Xvid uses MPEG-4 Advanced Simple Profile (ASP) compression, video encoded with Xvid is MPEG-4 ASP video (not "Xvid video"), and can therefore theoretically be decoded with all ASP-compliant decoders. This includes

4940-416: The total nominal capacity of a DVD-10 disc to 9.4 GB (8.75 GiB), but each side is locked to 4.7 GB. Like DVD-5 discs, DVD-10 discs are defined as single-layer (SL) discs. DVD hardware accesses the additional layer (layer 1) by refocusing the laser through an otherwise normally-placed, semitransparent first layer (layer 0). This laser refocus—and the subsequent time needed to reacquire laser tracking—can cause

5016-430: The ubiquitous VHS tape as the primary consumer video distribution format.
