The DVD Forum is an international organization composed of hardware, software, media and production companies that use and develop the DVD and formerly HD DVD formats. It was initially known as the DVD Consortium when it was founded in 1995.
The DVD Forum was created to facilitate the exchange of information and ideas about the DVD format, another evolution of the LaserDisc format, and to enable it to grow through technical improvement and innovation. The organization hopes to promote worldwide acceptance of DVD for entertainment, consumer electronics and information technology applications. Membership in the DVD Forum is open to any company or organization involved in DVD research, development, or manufacturing; software firms and other DVD users interested in developing the format are also encouraged to join. Forum members can support other formats in addition to DVD.[ citation needed ]
The DVD Forum is responsible for the official DVD format specification. The group handles licensing of the DVD format and logo through the DVD Format and Logo Licensing Corporation (DVD FLLC), which also publishes the official "DVD Book" format specifications. [1] Reference materials and newsletters are published for DVD Forum members.[ citation needed ]
In 2003, the DVD Forum had 213 members. [2] In 2007, it had 195 registered members. [3] In 2008, it had 159 registered members, [4] and in 2010, it had 98 registered members. [5] In 2012 this downward trend continued with the membership standing at 80 members. [6] Since 1 April 2012, the Forum is in a "Reduced Activity Mode", [7] however the DVD FLLC is still active as of 2020. [8]

Ten companies founded the organization:
Competing standards developed by the rival DVD+RW Alliance are for the "plus" formats (DVD+R, DVD+RW). Alliance leaders Philips, Sony and Thomson were also founding members of the DVD Forum, established in 1997. As of 2009 [update] , both plus and dash formats seem equally popular with customers, and both are compatible with the vast majority of DVD players.
JVC is a Japanese brand owned by JVCKenwood. Founded in 1927 as the Victor Talking Machine Company of Japan and later as Victor Company of Japan, Ltd., the company was best known for introducing Japan's first televisions and for developing the Video Home System (VHS) video recorder.
DVD-RAM is a DVD-based disc specification presented in 1996 by the DVD Forum, which specifies rewritable DVD-RAM media and the appropriate DVD writers. DVD-RAM media have been used in computers as well as camcorders and personal video recorders since 1998.
The DVD+RW Alliance is a group of electronic hardware, optical storage and software manufacturers who in 1997 created and promoted a format standard of recordable and rewritable DVDs, known as the "plus" format. As of 2004, plus format DVDs were available in three forms: DVD+R, DVD+RW, and DVD+R DL. In late 2005 DVD+RW DL was developed but never produced commercially.
The DualDisc is a type of double-sided optical disc product developed by a group of record companies including MJJ Productions Inc., EMI Music, Universal Music Group, Sony BMG Music Entertainment, Warner Music Group, and 5.1 Entertainment Group and later under the aegis of the Recording Industry Association of America (RIAA). It featured an audio layer intended to be compatible with CD players on one side and a standard DVD layer on the other. In this respect it was similar to, but distinct from, the DVDplus developed in Europe by Dieter Dierks and covered by European patents.
DigitalLiving Network Alliance (DLNA) is a set of interoperability standards for sharing home digital media among multimedia devices. It allows users to share or stream stored media files to various certified devices on the same network like PCs, smartphones, TV sets, game consoles, stereo systems, and NASs. DLNA incorporates several existing public standards, including Universal Plug and Play (UPnP) for media management and device discovery and control, wired and wireless networking standards, and widely used digital media formats. Many routers and network attached storage (NAS) devices have built-in DLNA support, as well as software applications like Windows Media Player.
The Blu-ray Disc Association (BDA) is the industry consortium that develops and licenses Blu-ray Disc technology and is responsible for establishing format standards and promoting business opportunities for Blu-ray Disc. The BDA is divided into three levels of membership: the board of directors, contributors, and general members.
The USB Implementers Forum (USB-IF) is a nonprofit organization created to promote and maintain USB, a set of specifications and transmission procedures for a type of cable connection that has since become used widely for electronic equipment. Its main activities are currently the promotion and marketing of USB, Wireless USB, USB On-The-Go, and the maintenance of standards and specifications for the related devices, as well as a compliance program.
Kornelis Antonie "Kees" Schouhamer Immink is a Dutch engineer, inventor, and entrepreneur, who pioneered and advanced the era of digital audio, video, and data recording, including popular digital media such as compact disc (CD), DVD and Blu-ray disc. He has been a prolific and influential engineer, who holds more than 1100 U.S. and international patents. A large portion of the commonly used audio and video playback and recording devices use technologies based on his work. His contributions to coding systems assisted the digital video and audio revolution, by enabling reliable data storage at information densities previously unattainable.
DVD recordable and DVD rewritable are optical disc recording technologies. Both terms describe DVD optical discs that can be written to by a DVD recorder, whereas only 'rewritable' discs are able to erase and rewrite data. Data is written ('burned') to the disc by a laser, rather than the data being 'pressed' onto the disc during manufacture, like a DVD-ROM. Pressing is used in mass production, primarily for the distribution of home video.
The OpenAjax Alliance is an industry group dedicated to the set of technologies and web programming techniques known as Ajax.
The Consumer Electronics Linux Forum was a non-profit organization to advance the Linux operating system as an open-source software platform for consumer electronics (CE) devices. It had a primarily technical focus, working on specifications, implementations, conferences and testing to help Linux developers improve Linux for use in CE products. It existed from 2003 to 2010.
The Open Grid Forum (OGF) is a community of users, developers, and vendors for standardization of grid computing. It was formed in 2006 in a merger of the Global Grid Forum and the Enterprise Grid Alliance. The OGF models its process on the Internet Engineering Task Force (IETF), and produces documents with many acronyms such as OGSA, OGSI, and JSDL.
The DVD-VR standard defines a logical format for video recording on DVD-R, DVD-RW, and DVD-RAM style media, including the dual layer versions of these media. As opposed to media recorded with the DVD+VR recording standard, the resulting media are not DVD-Video compliant, and do not play back in some DVD-Video players. Most DVD video recorders in the market that support DVD-R, DVD-RW, or DVD-RAM media record to these media in DVD-VR mode, as well as in a DVD-Video compliant mode. It is possible to use the DVD-VR format with DVD+R and DVD+RW media, but no examples are known other than some PC based recording utilities.
The DVD is a digital optical disc data storage format. It was invented and developed in 1995 and first released on November 1, 1996, in Japan. The medium can store any kind of digital data and has been widely used to store video programs, software and other computer files. DVDs offer significantly higher storage capacity than compact discs (CD) while having the same dimensions. A standard single-layer DVD can store up to 4.7 GB of data, a dual-layer DVD up to 8.5 GB. Variants can store up to a maximum of 17.08 GB.
Blu-ray is a digital optical disc data storage format designed to supersede the DVD format. It was invented and developed in 2005 and released worldwide on June 20, 2006, capable of storing several hours of high-definition video. The main application of Blu-ray is as a medium for video material such as feature films and for the physical distribution of video games for the PlayStation 3, PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X. The name refers to the blue laser used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs.
HD DVD is an obsolete high-density optical disc format for storing data and playback of high-definition video. Supported principally by Toshiba, HD DVD was envisioned to be the successor to the standard DVD format, but lost to Blu-ray, supported by Sony and others.
MIPI Alliance is a global business alliance that develops technical specifications for the mobile ecosystem, particularly smart phones but including mobile-influenced industries. MIPI was founded in 2003 by Arm, Intel, Nokia, Samsung, STMicroelectronics and Texas Instruments.
The high-definition optical disc format war was a market competition between the Blu-ray and HD DVD optical disc standards for storing high-definition video and audio; it took place between 2006 and 2008 and was won by Blu-ray Disc.
DVD-Video is a consumer video format used to store digital video on DVDs. DVD-Video was the dominant consumer home video format in Asia, North America, Europe, and Australia in the 2000s until it was supplanted by the high-definition Blu-ray Disc, before eventually both were replaced by streaming services such as Netflix and Disney+. Discs using the DVD-Video specification require a DVD drive and an MPEG-2 decoder. Commercial DVD movies are encoded using a combination of MPEG-2 compressed video and audio of varying formats. Typically, the data rate for DVD movies ranges from 3 to 9.5 Mbit/s, and the bit rate is usually adaptive. DVD-Video was first available in Japan on November 1, 1996, followed by a release on March 26, 1997, in the United States—to line up with the 69th Academy Awards that same day.
Super Video CD is a digital format for storing video on standard compact discs. SVCD was intended as a successor to Video CD and an alternative to DVD-Video, and falls somewhere between both in terms of technical capability and picture quality.
