.HD DVD (short for High Definition Digital Versatile Disc) is an obsolete high-density format for storing data and playback of. Supported principally by, HD DVD was envisioned to be the successor to the standard format.On February 19, 2008, after a protracted with rival, Toshiba abandoned the format, announcing it would no longer manufacture HD DVD players and drives. The HD DVD Promotion Group was dissolved on March 28, 2008.The HD DVD physical disc specifications (but not the ) were used as the basis for the (CBHD) formerly called CH-DVD.Because all variants except and HD REC employed a with a shorter wavelength, HD DVD stored about 3.2 times as much data per layer as its predecessor (maximum capacity: 15 GB per layer compared to 4.7 GB per layer). Contents.History In the late 1990s, commercial sets started to enter a larger market, but there was no inexpensive way to record or play back HD content. 's and 's formats could store that amount of data, but were neither popular nor well-known.

The DVD In 1997 the DVD format was born and Video Essentials (VE) was the best option for people who wanted to calibrate their audio/video. The DVD In 1997 the DVD format was born and Video Essentials (VE) was the best option for people who wanted to calibrate their audio/video home theater systems without the help of expensive home theater professionals.During those first few years, Video Essentials sold over 300,000 copies and became an essential tool for videophiles. (No pun intended).

It was well known that using lasers with shorter wavelengths would yield optical storage with higher density. Invented practical, but a lengthy patent lawsuit delayed commercial introduction. Origins and competition from Blu-ray Disc Sony started two projects applying the new diodes: (Ultra Density Optical) and DVR Blue together with Philips, a format of rewritable discs which would eventually become Blu-ray Disc (more specifically, BD-RE) and later on with Pioneer a format of read only discs (BD-ROM).

The two formats share several technologies (such as the AV codecs and the laser diode). In February 2002, the project was officially announced as Blu-ray Disc, and the was founded by the nine initial members.The (chaired by Sony) was deeply split over whether to go with the more expensive blue lasers or not.

Although today's Blu-ray Discs appear virtually identical to a standard DVD, when the Blu-ray Discs were initially developed they required a protective to avoid mis-handling by the consumer (early CD-Rs also featured a protective caddy for the same purpose.) The Blu-ray Disc prototype's caddy was both expensive and physically different from DVD, posing several problems. In March 2002, the forum voted to approve a proposal endorsed by and other that involved compressing HD content onto dual-layer discs. In spite of this decision, the DVD Forum's Steering Committee announced in April that it was pursuing its own blue-laser high-definition solution. In August, Toshiba and NEC announced their competing standard Advanced Optical Disc. It was adopted by the DVD forum and renamed to HD DVD the next year.The HD DVD Promotion Group was a group of manufacturers and media studios formed to exchange thoughts and ideas to help promote the format worldwide. Its members comprised Toshiba as the Chair Company and Secretary, Memory-Tech Corporation and as Vice-Chair companies, and Electric as Auditors; there were 61 general members and 72 associate members in total. The HD DVD promotion group was officially dissolved on March 28, 2008, following Toshiba's announcement on February 19, 2008 that it would no longer develop or manufacture HD DVD players and drives.Attempts to avoid a format war.

Main article:Much like the vs. During the late 1970s and early 1980s, HD DVD was competing with a rival format—in this case, Blu-ray Disc. In 2008, major content manufacturers and key retailers began withdrawing their support for the format.In an attempt to avoid a costly format war, the Blu-ray Disc Association and DVD Forum attempted to negotiate a compromise in early 2005. One of the issues was that Blu-ray Disc companies wanted to use a Java-based platform for interactivity ( based on ' standards), while HD DVD companies wanted to use Microsoft's 'iHD' (which became ). Another problem was the physical formats of the discs themselves. The negotiations proceeded slowly and ultimately stalled.On August 22, 2005, the Blu-ray Disc Association and DVD Forum announced that the negotiations to unify their standards had failed.

Rumors surfaced that talks had stalled; publicly, the same reasons of physical format incompatibility were cited. By the end of September that year, Microsoft and Intel jointly announced their support for HD DVD.(HP) attempted to broker a compromise between the Blu-ray Disc Association and Microsoft by demanding that Blu-ray Disc use Microsoft's instead of BD-J and threatening to support HD DVD instead. The Blu-ray Disc Association did not agree to HP's demands. In November 2006, Microsoft released an for their game console for $199. It came packaged with and could only play movies.On March 31, 2006, Toshiba released their first consumer-based HD DVD player in Japan at 110,000 (US$934). HD DVD was released in the United States on April 18, 2006, with players priced at $499 and $799.The first HD DVD titles were released on April 18, 2006.

They were, and by. The first independent HD film released on HD DVD was. Main article:If a publisher wishes to restrict use of its HD DVD content, it may use the Advanced Access Content System although this is not required for normal disc playback. AACS is a standard for. It is developed by AACS Licensing Administrator, LLC (AACS LA), a that includes, Microsoft, Warner Bros., Toshiba. One of the advantages over, the content restriction system for DVDs, is that AACS allows content providers to revoke an individual player device model if its cryptographic keys have been compromised (meaning that it will not be able to decrypt subsequently released content).

There is no in the existing HD DVD specification, which means that titles from any country can be played in players in any other country.Since appearing in devices in 2006, several successful attacks have been made on the format. The first known attack relied on the problem. In addition, decryption keys have been extracted from a weakly protected player. Notably, a Processing Key was found that could be used to decrypt all HD content that had been released at the time. The processing key was widely published on the Internet after it was found and the AACS LA sent multiple notices with the aim of censoring it. This caused trouble on some sites that rely on user-submitted content, like and, when administrators tried to remove any mentions of the key. Further information:AACS has also been circumvented by with their program HD, which allows users to watch HD DVD movies on non-compliant PC hardware.

SlySoft has stated that AnyDVD HD uses several different mechanisms to disable the encryption, and is not dependent on the use of a single compromised encryption key.Other AACS circumvention programs have become available, like DVDFab HD Decrypter. Interactive content HD DVDs use to allow interactive content to be authored for discs. Microsoft's implementation of Advanced Content is the, and 'HDi' is frequently used to refer to the Advanced Content system. Advanced Content is based on web technologies such as, and , so authoring in Advanced Content should be a fairly easy transition for web developers. No existing DVD authoring experience is required. In comparison, Blu-ray Disc content is authored using either a scripting environment (BDMV) or a Java-based platform. DVD video discs use pre-rendered MPEG segments, selectable subtitle pictures, and simple programmatic navigation which is considerably more limited.Hardware Compatibility is available with all HD DVD players, allowing users to have a single player to play all types of HD DVD, DVD and CD.

There is also a hybrid HD DVD format which contains both DVD and HD DVD versions of the same movie on a single disc, providing a smooth transition for the studios in terms of publishing movies, and allowing consumers with only DVD players to still use the discs. DVD replication companies can continue using their current production equipment with only minor alterations when changing over to the format of HD DVD replication. Due to the structure of the single-lens optical head, both red and blue laser diodes can be used in smaller, more compact HD DVD players.General purpose computers HD DVD drives can also be used with a desktop/laptop personal computer (PC) running, 'Leopard', and many varieties of. Third-party player software for Windows and Linux have successfully played HD DVD titles using the add-on drive.Released at the end of November 2006, the HD DVD drive for the game-console gives the Xbox 360 the ability to play HD DVD movies. The drive was announced with an of US$199 and includes a for connection to the console. The first drives also included Peter Jackson's or Christopher Nolan's on HD DVD.

The final 'regular' for the drive was US$129.99 as of February 25, 2008. On February 23, 2008 Microsoft discontinued the Xbox 360 HD DVD player. On February 26, 2008, Microsoft 'officially' announced that the Xbox 360 HD DVD add on drive would reflect a heavily discounted price down to $49.99. Dual-compatibility drives In 2007, and released standalone consumer players that could read both HD DVD and Blu-ray Discs. The machines were sold at premium prices, but failed to sell in large quantities. In May 2008, both companies announced they would stop manufacturing dual-compatibility drives.A few computer manufacturers (such as HP and ) sold computers with combination HD DVD/Blu-ray Disc drives. LG marketed a Blu-ray writer that also read HD DVD discs (but could not write to them).

HD DVD / Blu-ray Disc comparison. Main article:HD DVD competed primarily with Blu-ray Disc. Both formats were designed as successors to, capable of higher quality video and audio playback, and of greater capacity when used to store video, audio, and computer data. Blu-ray Disc and HD DVD share most of the same methods of encoding media onto discs with each other, resulting in equivalent levels of audio and visual quality, but differ in other aspects such as interactive capabilities, internet integration, usage control and enforcement, and in which features were mandatory for players.

The storage size also varies: A dual-layer HD DVD holds a maximum of 30 GB of data, while a dual-layer Blu-ray Disc carries 50 GB.Development Even after finalizing the HD DVD standard, engineers continued developing the technology. A 51 GB triple-layer spec was approved at the DVD Forums 40th Steering Committee Meeting (held on November 15, 2007). No movies had been scheduled for this disc type, and Toshiba had declined to say whether the 51 GB disc was compatible with existing drives and players. Specification 2.0 Part 1 (Physical Specification) for triple layer HD DVD had been approved in November 2007.At the 2007, revealed their high definition optical disc process that extended both competing high definition formats to ten layers, increasing capacity to 150 GB for HD DVD and 250 GB for Blu-ray Disc.

A major obstacle to implementing this technology in either format (150 GB HD DVD will not be developed due to HD DVD's discontinuation) is that reader-writer technology available may not be able to support the additional data layers., and have separately developed a single chip/laser that can read both the HD DVD and the Blu-ray Disc standard. Broadcom and STMicroelectronics will be selling their dual-format single chip/laser solution to any willing to develop a product based on the chip.Variants and media HD DVD-R / -RW / -RAM HD DVD-R is the writable disc variant of HD DVD, available with a single-layer capacity of 15 GB or a dual-layer capacity of 30 GB. Write speeds depend on drive speed, with a data rate of 36.55 Mbit/s (4.36 MB/s) and a recording time of 56 minutes for 1× media, and 73 Mbit/s (8.71 MB/s) and a recording time of 28 minutes for 2×.The Toshiba SD-L902A for notebooks was one of the first available HD DVD writers, although it was not meant for retail. Burning HD DVD (including Dual Layer) with a 1× write speed, it could also burn DVDs and CDs. In a test of the SD-L902A by with discs, the written HD DVD-Rs suffered from high noise levels, as a result, the written discs could not be recognized by the, though they could be read back by the SD-L902A.HD DVD-RW is the rewritable disc variant of HD DVD with equal storage capacity to an HD DVD-R. The primary advantage of HD DVD-RW over HD DVD-R is the ability to erase and rewrite to an HD DVD-RW disc, up to about 1,000 times before needing replacement, making them comparable with the and standards. This is also of benefit if there are writing errors when recording data, as the disc is not ruined and can still store data by erasing the faulty data.HD DVD-RAM was the proposed successor to for random access on optical media using phase-change principals.

It would hold 20 gigabytes per layer instead of 15 gigabytes for HD DVD-R, due to differences in recording methods used, yielding a higher density disc.DVD / HD DVD hybrid discs There are two types of hybrid formats which contain standard DVD-Video format video for playback in regular DVD players, and HD DVD video for playback in high definition on HD DVD players. The Combo disc is a dual sided disc with one side DVD and the other HD DVD, each of which can have up to two layers. The Twin disc is a single sided disc that can have up to three layers, with up to two layers dedicated to either DVD or HD DVD. These hybrid discs make retail marketing and shelf space management easier. Another advantage is hardware cross-compatibility. The average consumer does not have to worry about whether or not they can play a hybrid DVD: any standard home DVD player can access the DVD-encoded content and any HD DVD player can access both the DVD- and HD DVD-encoded content.HD DVD / Blu-ray Disc hybrid discs Warner Bros. Officially announced (THD or Total HD) at.

THD hybrid discs were to support both HD DVD and Blu-ray Disc, with HD DVD on one side (up to two layers) and Blu-ray Disc on the other side (up to two layers). In November 2007, Warner Bros.

Cancelled THD's development. 3× DVD The HD DVD format also applies to current red laser DVDs; this type of disc is called '3× DVD', as it is capable of three times the bandwidth of regular.3× DVDs are physically identical to normal DVDs. Although 3× DVDs provide the same high definition content, their playback time is less. For example, an 8.5 GB DVD can hold about 90 minutes of 1080p video encoded with VC-1 or AVC at an average bitrate of 12 Mbit/s, which corresponds with the average length of Hollywood feature-films. If quality is compromised slightly, and good compression techniques are used, most feature films could be encoded with 3× DVD.

Due to its much greater resolution, HD-Video also has significantly more redundant information than DVD which newer compression standards can encode more efficiently.It is technically possible for consumers to create HD DVD compatible discs using low cost DVD-R or DVD+R media. At least one such guide exists. The 3× DVD is comparable to Blu-ray Disc.HD REC HD Rec is an extension of the HD DVD format for recording HD content on regular red laser DVD-Rs/DVD-RWs using compression. It was approved by the on September 12, 2007 It is comparable to Blu-ray Disc's.CBHD The (CBHD), a high-definition optical disc format, was based upon the HD DVD format. Like the HD DVD, CBHD discs have a capacity of 15 GB single-layer and 30 GB dual-layer and can use existing DVD production lines. Unlike the HD DVD format, industry support for this format has grown steadily.
