202-682: A BD player. Japanese optical disc manufacturer Infinity announced the first "hybrid" Blu-ray Disc/(standard) DVD combo, to be released on February 18, 2009. This disc set of the TV series Code Blue featured four hybrid discs containing a single Blu-ray Disc layer (25 GB) and two DVD layers (9 GB) on the same side of the disc. In January 2007, Hitachi showcased a 100 GB Blu-ray Disc, consisting of four layers containing 25 GB each. It claimed that, unlike TDK's and Panasonic 's 100 GB discs, this disc would be readable on standard Blu-ray Disc drives that were currently in circulation, and it
303-652: A Blu-ray player. The information density of the DVD format was limited by the wavelength of the laser diodes used. Following protracted development, blue laser diodes operating at 405 nanometers became available on a production basis, allowing for the development of a denser storage format that could hold higher-definition media, with prototype discs made with diodes at a slightly longer wavelength of 407 nanometers in October 1998. Sony commenced two projects in collaboration with Panasonic , Philips , and TDK , applying

More recent half-height Blu-Ray writers have reached writing speeds of up to 16× ( constant angular velocity ) on single-layer BD-R media, while the highest reading speeds are 12×, presumably to prevent repeated physical stress on the disc. Slim type drives are limited to 6× speeds (constant angular velocity) due to spacial and power limitations. The Blu-ray format has
606-521: A chain reaction in the industry, with major American retailers such as Best Buy , Walmart , and Circuit City and Canadian chains such as Future Shop dropping HD DVD in their stores. Woolworths , then a major European retailer, dropped HD DVD from its inventory. Major DVD rental companies Netflix and Blockbuster said they would no longer carry HD DVD. Following these new developments, on February 19, 2008, Toshiba announced it would end production of HD DVD devices, allowing Blu-ray Disc to become

Region-free players are DVD players shipped without the ability to enforce regional lockout (usually by means of a chip that ignores any region coding), or without this flag set. However, if the player is not region-free, it can often be unlocked with an unlock code entered via

However, the final AACS standard was delayed, and then delayed again when an important member of the Blu-ray Disc group voiced concerns. At the request of the initial hardware manufacturers, including Toshiba, Pioneer, and Samsung, an interim standard
909-683: A day before CES 2008, Warner Bros. , the only major studio still releasing movies in both HD DVD and Blu-ray Disc format, announced that it would release only in Blu-ray after May 2008. This effectively included other studios that came under the Warner umbrella, such as New Line Cinema and HBO —though in Europe, HBO's distribution partner, the BBC , announced it would continue to release product on both formats while keeping an eye on market forces. This led to

A region-free or RCE-protected DVD will carry the value zero, since no regions are excluded. The Xbox , Xbox 360 , PlayStation 2 and PlayStation 3 consoles are all region-locked for DVD playback. The PlayStation 2 can be modified to have its regional-locking disabled through

Recordable (BD-R) and rewritable (BD-RE) versions of Mini Blu-ray Disc have been developed specifically for compact camcorders and other compact recording devices. " Blu-ray Disc recordable " (BD-R) refers to two optical disc formats that can be recorded with an optical disc recorder . BD-Rs can be written to once, whereas Blu-ray Disc Recordable Erasable (BD-REs) can be erased and re-recorded multiple times. The current practical maximum speed for Blu-ray Discs

Spreading out release dates allows for reuse of some release prints in other regions. For example, the film 28 Days Later was available on DVD in the United Kingdom before it was released in theaters in

On July 20, 2010, the research team of Sony and Japanese Tohoku University announced the joint development of a blue-violet laser, to help create Blu-ray Discs with a capacity of 1 TB using only two layers (and potentially more than 1 TB with additional layering). By comparison, the first blue laser was invented in 1996, with

No systems conforming to the Ecma International HVD standard have been released. The company responsible for HVD went bankrupt in 2010, making any releases unlikely. A boutique Blu-ray label or specialty Blu-ray label
1818-660: A region-free player to view NTSC discs (with the possible exception of Japanese discs in most European countries, since they are in the same region - this means European region 2 users could import Japanese discs and play them on their players without any obstacles.) There are also differences in pixel aspect ratio (720 × 480 vs. 720 × 576 with the same image aspect ratio ) and display frame rate (29.97 vs. 25). Most computer-based DVD software and hardware can play both NTSC and PAL video and both audio standards. Blu-ray players, which use up to 1080p signals, are backwards compatible with both NTSC and PAL DVDs. Usually,

If it cannot play the disc, then it tries another region until one is found that works. RCE could be defeated by briefly playing a "normal" region 1 disc, and then inserting the RCE protected region 1 disc, which would now play. RCE also caused a few problems with genuine region 1 players. Many "multi-region" DVD players defeated regional lockout and RCE by automatically identifying and matching
2020-476: A resolution supported by the Blu-ray specification. Besides these hardware specifications, Blu-ray is associated with a set of multimedia formats. Given that Blu-ray discs can contain ordinary computer files , there is no fixed limit as to which resolution of video can be stored when not conforming to the official specifications. The BD format was developed by the Blu-ray Disc Association ,

The intention was that when the disc was played in a non-region 1 player, the player would default to playing the material for its native region. This played the aforementioned video loop of a map, which was impossible to escape from, as the user controls were disabled. The scheme was fundamentally flawed, as

So-called "Region 0" and "ALL" discs are meant to be playable worldwide. The term "Region 0" also describes the DVD players designed or modified to incorporate Regions 1–8, thereby providing compatibility with most discs, regardless of region. This apparent solution

"D1" are the UK only releases; "D2" and "D3" are not sold in the UK and Ireland; "D4" are distributed throughout Europe. Overseas territories of the United Kingdom and France (both in region 2) often have other regions (4 or 5, depending on geographical situation) than their homelands. Most DVDs sold in Mexico and the rest of Latin America carry both region 1 and 4 codes. Some are region 1 only after 2006 to coincide with Blu-ray region A. Egypt, Eswatini, Lesotho, and South Africa are in DVD region 2, while all other African countries are in region 5, but all African countries are in

In an effort to increase sales, studios began releasing films in combo packs with Blu-ray Discs and DVDs, as well as digital copies that can be played on computers and mobile devices. Some are released on "flipper" discs with Blu-ray on one side and DVD on the other. Other strategies are to release movies with

In 2007, Hitachi was reported to have plans to produce 200 GB discs by 2009. Behind closed doors at CES 2007, Ritek revealed that it had successfully developed a high-definition optical disc process that extended the disc capacity to ten layers, increasing the capacity of

Boutique Blu-ray labels, which are popular among collectors and enthusiasts of film and physical media , have been credited as a factor in a "Blu-ray renaissance" dating back to at least 2018, with some consumers choosing to purchase films on physical formats in an age of digital streaming. Reasons some consumers prefer Blu-rays to streaming include higher video quality,

Nielsen VideoScan sales numbers showed that for some titles, such as 20th Century Fox's Hitman , up to 14% of total disc sales were from Blu-ray, although the average Blu-ray sales for the first half of the year were only around 5%. In December 2008,

It was finally adopted by the DVD Forum and renamed HD DVD the next year, after being voted down twice by DVD Forum members who were also Blu-ray Disc Association members—a situation that drew preliminary investigations by the U.S. Department of Justice . HD DVD had a head start in the high-definition video market, as Blu-ray Disc sales were slow to gain market share. The first Blu-ray Disc player
4040-562: The Blu-ray Disc specification has been finalized, engineers continue to work on advancing the technology. By 2005, quad-layer (100 GB) discs had been demonstrated on a drive with modified optics and standard unaltered optics. Hitachi stated that such a disc could be used to store 7 hours of 32 Mbit/s video (HDTV) or 3 hours and 30 minutes of 64 Mbit/s video ( ultra-high-definition television ). In April 2006, TDK canceled plans to produce 8-layer 200 GB Blu-ray Discs. In August 2006, TDK announced that it had created

On January 1, 2010, Sony, in association with Panasonic, announced plans to increase the storage capacity on their Blu-ray Discs from 25 GB to 33.4 GB via a technology called i-MLSE ( maximum likelihood sequence estimation ). The higher-capacity discs, according to Sony, would be readable on existing Blu-ray Disc players with
4444-409: The United States. Videotapes were inherently regional since formats had to match those of the encoding system used by television stations in that particular region, such as NTSC and PAL , although from the early 1990s PAL machines increasingly offered NTSC playback . DVDs are less restricted in that sense. Region coding allows movie studios to better control the global release dates of DVDs. Also,

In 2012, a report from The Sydney Morning Herald revealed that region-free DVD players were legal in Australia, as they were exempt from the Technological Protection Measures (TPMs) included in the US Free Trade Agreement. Under New Zealand copyright law, DVD region codes and

In the mid-2010s, the Ultra HD Blu-ray format was released which is an enhanced variant of Blu-ray compatible with the 4K resolution . Ultra HD Blu-ray discs and players became available in the first quarter of 2016, having a storage capacity of up to 100 GB. By December 2017, the specification for an 8K Blu-ray format
4747-444: The amount of content that can be stored. Given that the Blu-ray Disc data layer is closer to the surface of the disc compared to the DVD standard, it was found in early designs to be more vulnerable to scratches. The first discs were therefore housed in cartridges for protection, resembling Professional Discs introduced by Sony in 2003. Using a cartridge would increase the price of an already expensive medium, and would increase
4848-560: The converted signal. NTSC discs may be output from a PAL DVD player in three different ways: However, most NTSC players cannot play PAL discs, and most NTSC TVs do not accept 576i video signals as used on PAL/SECAM DVDs. Those in NTSC countries, such as the United States, generally require both a region-free, multi-standard player and a multi-standard television to view PAL discs, or a converter box, whereas those in PAL countries generally require only
4949-682: The copyright in a title may be held by different entities in different territories. Region coding enables copyright holders to (attempt to) prevent a DVD from a region from which they do not derive royalties from being played on a DVD player inside their region. Region coding attempts to dissuade importing of DVDs from one region into another. DVDs are also formatted for use on two conflicting regional television systems: 480i /60 Hz and 576i /50 Hz, which in analog contexts are often referred to as 525/60 ( NTSC ) and 625/50 ( PAL / SECAM ) respectively. Strictly speaking, PAL and SECAM are analog color television signal formats which have no relevance in

PAL is the analog color TV format historically associated with most of Europe, most of Africa, China, India, Australia, New Zealand, Israel, North Korea, and other countries (Brazil adopted the variant PAL-M , which uses
5151-655: The country code allows much more precise control of the regional distribution of Blu-ray discs than the six (or eight) DVD regions. In Blu-ray discs, there are not any "special regions" like the regions 7 and 8 in DVDs. Ultra HD (4K) Blu-Ray discs are region-free as they're generally encoded as worldwide region. For the UMD, a disc type used for the PlayStation Portable , UMD movies have region codes similar to DVDs, although many PSP games are region-free. Region coding

Sony also announced in April 2004 a version using paper as the substrate developed with Toppan Printing, with up to 25 GB storage. In January 2005, TDK announced that it had developed an ultra-hard yet very thin polymer coating (" Durabis ") for Blu-ray Discs; this

However, the DVD system was originally designed to encode the information necessary to reproduce signals in these formats, and the terms continue to be used (incorrectly) as a method of identifying refresh rates and vertical resolution. However, an "NTSC", "PAL" or "SECAM" DVD player that has one or more analog composite video output (baseband or modulated) will only produce NTSC, PAL or SECAM signals, respectively, from those outputs, and may only play DVDs identified with

JVC developed a three-layer technology that allows putting both standard-definition DVD data and HD data on a BD/(standard) DVD combination. This would have enabled the consumer to purchase a disc that can be played on DVD players and can also reveal its HD version when played on
5555-438: The drive allows DVDs from any region to play. Newer drives use RPC-2 firmware, which enforces the DVD region coding at the hardware level. These drives can often be reflashed or hacked with RPC-1 firmware, effectively making the drive region-free. This may void the drive's warranty. Some drives may come set as region-free, so the user is expected to assign their region when they buy it. In this case, some DVD programs may prompt
5656-651: The drive is locked. Most commercial players are locked to a region code, but can be easily changed with software. Other software, known as DVD region killers, transparently remove (or hide) the DVD region code from the software player. Some can also work around locked RPC-2 firmware. The region coding of a DVD can be circumvented by making a copy that adds flags for all region codes, creating an all-region DVD. DVD backup software can do this, and some can also remove Macrovision , CSS , and disabled user operations (UOps). In common region-locked DVDs (but not in RCE-DVDs),

Since some software does not work correctly with RPC-1 drives, there is also the option of reflashing the drive with a so-called auto-reset firmware. This firmware appears as RPC-2 firmware to software, but will reset the region changes counter whenever power is cycled, reverting to

"Mastered in 4K" Blu-ray Disc titles can be played on existing Blu-ray Disc players and have a larger color space using xvYCC . On January 14, 2013, Blu-ray Disc Association president Andy Parsons stated that

At CES 2007 , Warner proposed Total Hi Def —a hybrid disc containing Blu-ray on one side and HD DVD on the other, but it was never released. On June 28, 2007, 20th Century Fox cited Blu-ray Discs' adoption of the BD+ anticopying system as key to their decision to support the Blu-ray Disc format. On January 4, 2008,
6161-579: The first two years (1997–1998) compared to 8.3 million high-definition software units (2006–2007). One reason given for this difference was the smaller marketplace (26.5 million HDTVs in 2007 compared to 100 million SDTVs in 1998). Former HD DVD supporter Microsoft did not make a Blu-ray Disc drive for the Xbox 360 . The 360's successor Xbox One features a Blu-ray drive, as does the PS4, with both supporting 3D Blu-ray after later firmware updates . Shortly after

The Blu-ray Disc specification requires the testing of resistance to scratches by mechanical abrasion . In contrast, DVD media are not required to be scratch-resistant, but since development of the technology, some companies, such as Verbatim, implemented hard-coating for more expensive lines of recordable DVDs.

Paramount Pictures , which started releasing movies only in HD DVD format during late 2007, also said it would start releasing on Blu-ray Disc. Both studios announced initial Blu-ray lineups in May 2008. With this, all major Hollywood studios supported Blu-ray. Although

6767-477: The new diodes: UDO (Ultra Density Optical), and DVR Blue (together with Pioneer ), a format of rewritable discs that would eventually become Blu-ray Disc (more specifically, BD-RE). The core technologies of the formats are similar. The first DVR Blue prototypes were unveiled by Sony at the CEATEC exhibition in October 2000. A trademark for the "Blue Disc" logo was filed on February 9, 2001. On February 19, 2002,
6868-435: The new format, and they wanted a new DRM system that would protect more against unauthorized copying than the failed Content Scramble System (CSS) used on DVDs. On October 4, 2004, the name Blu-ray Disc Founders was officially changed to the Blu-ray Disc Association (BDA), and 20th Century Fox joined the BDA's Board of Directors. The Blu-ray Disc physical specifications were completed in 2004. The recording layer on which
6969-423: The new format. New Ultra HD Blu-ray Discs hold up to 66 GB and 100 GB of data on dual- and triple-layer discs, respectively. Blu-ray's physical and file system specifications are publicly available on the BDA's website. According to Media Research, high-definition software sales in the United States were slower in the first two years than DVD software sales. 16.3 million DVD software units were sold in
7070-424: The package that was adopted worldwide following the Blu-ray versus HD DVD market adoption choice. Because Blu-ray cases are smaller than DVD cases, more Blu-rays than DVDs can fit on a shelf . The "Mini Blu-ray Disc" (also, "Mini-BD" and "Mini Blu-ray") is a compact 8-centimetre-diameter (3.1 in) variant of the Blu-ray Disc that can store 7.8 GB of data in its single-layer configuration, or 15.6 GB on
7171-519: The player software, not by the computer system or the drive, not like DVD regions. The region code is stored in a file or the registry, and there are hacks to reset the region counter of the player software. In standalone players, the region code is part of and enforced by the firmware. For bypassing region codes, there are software and multi-regional standalone players available. On the other hand, some standalone players can be modified to be region-free. A new form of Blu-ray region coding tests not only
7272-554: The project was officially announced as Blu-ray Disc, and Blu-ray Disc Founders was founded by the nine initial members. The first consumer device arrived in stores on April 10, 2003: the Sony BDZ-S77, a US$ 3,800 BD-RE recorder that was made available only in Japan. However, there was no standard for pre-recorded video, and no movies were released for this player. Hollywood studios insisted that players be equipped with digital rights management before they would release movies for
7373-437: The range between the brightest and darkest elements, an expanded color range, a high frame rate of up to 60 frames per second for a smoother motion appearance, an increase of the supported resolution to 3840 × 2160 for a more detailed picture, object-based sound formats, and an optional "digital bridge" feature. New players were required to play this format, and they became able to play all three of DVDs, traditional Blu-rays, and
7474-725: The rate of errors , of which higher rates may be an indication for deteriorating media , low-quality media, physical damage such as scratches, dust, and/or media written using a defective optical drive . Errors on Blu-Ray media are measured using the so-called LDC ( Long Distance Code s) and BIS ( Burst Indication Subcode s) error parameters, of which rates below 13 and 15 respectively can be considered healthy. Not all vendors and models of optical drives have error scanning functionality implemented. Pre-recorded Blu-ray Disc titles usually ship in packages similar to, but slightly smaller (18.5 mm shorter and 2 mm thinner: 135 mm × 171.5 mm × 13 mm ) and more rounded than,
7575-651: The refresh rate and resolution commonly associated with NTSC). SECAM, a format associated with French-speaking Europe, while using the same resolution and refresh rate as PAL, is a distinct format which uses a very different system of color encoding. Some DVD players can only play discs identified as NTSC, PAL or SECAM, while others can play multiple standards. In general, it is easier for consumers in PAL/SECAM countries to view NTSC DVDs than vice versa. Almost all DVD players sold in PAL/SECAM countries are capable of playing both kinds of discs, and most modern PAL TVs can handle
7676-408: The region 2, region 4, and region 5 codes, or are region 0. Region-code enhanced, also known as just "RCE" or "REA", was a retroactive attempt to prevent the playing of one region's discs in another region, even if the disc was played in a region-free player. The scheme was deployed on only a handful of discs. The disc contained the main program material region coded as region 1. But it also contained
7777-420: The region code is stored in the file "VIDEO_TS.IFO" (table "VMGM_MAT"), byte offsets 34 and 35. The eight regions each correspond to a value which is a power of 2: Region 1 corresponds to 1 (2 ), Region 2 to 2 (2 ), Region 3 to 4 (2 ), and so on through Region 8, which corresponds to 128 (2 ). The values of each region that the disc is not encoded for are added together to give the value in the file. For example,
7878-606: The region of the player/player software, but also its country code. This means, for example, while both the US and Japan are Region A, some American discs are not going to be played on devices/software installed in Japan or vice versa, due to the two countries having different country codes (the United States has 21843 or Hex 5553 ("US" in ASCII , according to ISO 3166-1 ), and Japan has 19024, or Hex 4a50 ("JP"); Canada has 17217 or Hex 4341 ("CA"). Although there are only three Blu-ray regions,
7979-491: The same Blu-ray region code (region B). North Korea and South Korea have different DVD region codes (North Korea: region 5, South Korea: region 3), but use the same Blu-ray region code (region A). In China, two DVD region codes are used: Mainland China uses region 6, but Hong Kong and Macau use region 3. There are also two Blu-ray regions used: China uses region C, while Hong Kong and Macau use region A. Most DVDs in India combine
8080-411: The same area. For a Blu-ray Disc, the spot size is 580 nm. This allows a reduction of the pit size from 400 nm for DVD to 150 nm for Blu-ray Disc, and of the track pitch from 740 nm to 320 nm. See compact disc for information on optical discs' physical structure. In addition to the optical improvements, Blu-ray Discs feature improvements in data encoding that further increase
8181-582: The same method used on standard DVDs. The first releases using the newer VC-1 and AVC formats were introduced in September 2006. The first movies using 50 GB dual-layer discs were introduced in October 2006. The first audio-only albums were released in May 2008. By June 2008, over 2,500 Blu-ray Disc titles were available in Australia and the United Kingdom, with 3,500 in the United States and Canada. In Japan, over 3,300 titles had been released as of July 2010. The DVD Forum , chaired by Toshiba ,

8383-582: The size of Blu-ray Disc drives, so designers chose hard-coating of the pickup surface instead. TDK was the first company to develop a working scratch-protection coating for Blu-ray Discs, naming it Durabis . In addition, both Sony's and Panasonic's replication methods include proprietary hard-coat technologies. Sony's rewritable media are spin-coated, using a scratch-resistant acrylic and antistatic coating. Verbatim 's recordable and rewritable Blu-ray Discs use their own proprietary technology, called Hard Coat. Colloidal silica-dispersed UV-curable resins are used for
8484-478: The special features only on Blu-ray Discs and none on DVDs. Blu-ray Discs cost no more to produce than DVD discs. However, reading and writing mechanisms are more complicated, making Blu-ray recorders, drives and players more expensive than their DVD counterparts. Adoption is also limited due to the widespread use of streaming media . Blu-ray Discs are used to distribute PlayStation 3 , PlayStation 4 , PlayStation 5 , Xbox One and Xbox Series X games, and
8585-426: The specification allowed newer Blu-ray players to support videos with a resolution of 1440 × 1080 pixels, with Ultra HD Blu-ray players extending the maximum resolution to 4K ( 3840 × 2160 pixels) and progressive frame rates up to 60 frames per second. Aside from an 8K resolution ( 7680 × 4320 pixels) Blu-ray format exclusive to Japan , videos with non-standard resolutions must use letterboxing to conform to
8686-414: The speeds available. Even the lowest speed (1×) is sufficient to play and record real-time 1080p video; the higher speeds are relevant for general data storage and more sophisticated handling of video. BD discs are designed to cope with at least 5,000 rpm of rotational speed. The usable data rate of a Blu-ray Disc drive can be limited by the capacity of the drive's data interface. With a USB 2.0 interface,
8787-418: The state of a drive that has never had its region code changed. Most freeware and open source DVD players ignore region coding. VLC , for example, does not attempt to enforce region coding; however, it requires access to the DVD's raw data to overcome CSS encryption, and such access may not be available on some drives with RPC-2 firmware when playing a disc from a different region than the region to which
8888-404: The tactile nature of owning a film physically, elaborate packaging, bonus features, and the desire to own or watch films that are not available in streaming services' libraries. While a DVD uses a 650 nm red laser, Blu-ray Disc uses a 405 nm " blue " laser diode . Although the laser is called "blue", its color is actually in the violet range. The shorter wavelength can be focused to
8989-557: The use of modchips . Although region locked on film DVDs and film Blu-ray Discs, the PlayStation 3 , PlayStation 4 , PlayStation 5 , Xbox One , and Xbox Series X are region free for video games, though add-on content on the online store is region locked and must match the region of the disc. Blu-ray discs use a much simpler region-code system than DVD with only three regions, labeled A, B and C. As with DVDs, many Blu-rays are encoded region 0 (region free), making them suitable for players worldwide. Blu-ray regions are verified only by
9090-447: The user to select a region, while others may actually assign the region automatically based on the locale set in the operating system. In most computer drives, users are allowed to change the region code up to five times. If the number of allowances reaches zero, the region last used will be permanent even if the drive is transferred to another computer. This limit is built into the drive's controller software, called firmware. Resetting
9191-509: Was a significant technical advance because a far tougher protection was desired in the consumer market to protect bare discs against scratching and damage compared to DVD, given that Blu-ray Discs technically required a much thinner layer for the denser and higher-frequency blue laser. Cartridges, originally used for scratch protection, were no longer necessary and were scrapped. The BD-ROM specifications were finalized in early 2006. Advanced Access Content System Licensing Administrator (AACS LA),
9292-481: Was adopted faster than the DVD format was at a similar period in its development. This conclusion was based on the fact that Singulus Technologies received orders for 21 Blu-ray dual-layer replication machines during the first quarter of 2008, while 17 DVD replication machines of this type were made in the same period in 1997. According to GfK Retail and Technology, in the first week of November 2008, sales of Blu-ray recorders surpassed DVD recorders in Japan. According to
9393-605: Was also completed. However, this specification was for Japan only so that it could be used by Japanese public broadcasters like NHK to broadcast in 8K resolution for the Tokyo 2020 Olympic Games in Japan. The Holographic Versatile Disc (HVD), described in the ECMA-377 standard, was in development by the Holography System Development (HSD) Forum using a green writing/reading laser (532 nm) and
9494-472: Was believed that a firmware update was the only requirement to make it readable by then-current players and drives. In October 2007, they revealed a 100 GB Blu-ray Disc drive. In December 2008, Pioneer Corporation unveiled a 400 GB Blu-ray Disc (containing 16 data layers, 25 GB each) compatible with current players after a firmware update. Its planned launch was in the 2009–10 time frame for ROM and 2010–13 for rewritable discs. Ongoing development
9595-583: Was criticized for facilitating unlawful market control strategies, such as price fixing . Sale of region-coded DVDs are illegal in New Zealand . The Australian Competition and Consumer Commission (ACCC) have warned that DVD players that enforce region-coding may violate the Competition and Consumer Act 2010 . A December 2000 report from the ACCC advised consumers to "exercise caution when purchasing
9696-511: Was perceived as expensive and buggy, and there were few titles available. The Sony PlayStation 3 , which contained a Blu-ray Disc player for primary storage, helped support Blu-ray. Sony also ran a more thorough and influential marketing campaign for the format. AVCHD camcorders were also introduced in 2006. These recordings can be played back on many Blu-ray Disc players without re-encoding but are not compatible with HD DVD players. By January 2007, Blu-ray Discs had outsold HD DVDs, and during
9797-527: Was popular in the early days of the DVD format, but studios quickly responded by adjusting discs to refuse to play in such machines by implementing a system known as "Regional Coding Enhancement" (RCE). DVDs sold in the Baltic states use both region 2 and 5 codes, having previously been in region 5 (because of their history as part of the USSR), but EU single market law concerning the free movement of goods caused
9898-567: Was published that did not include some features, such as managed copy, which would have let end users create copies limited to personal use. The first BD-ROM players (Samsung BD-P1000) were shipped in mid-June 2006, though HD DVD players beat them to market by a few months. The first Blu-ray Disc titles were released on June 20, 2006: 50 First Dates , The Fifth Element , Hitch , House of Flying Daggers , Underworld: Evolution , xXx (all from Sony), and MGM 's The Terminator . The earliest releases used MPEG-2 video compression,
9999-520: Was split over whether to develop the more expensive blue laser technology. In March 2002 the forum approved a proposal, which was endorsed by Warner Bros. and other motion picture studios . The proposal involved compressing high-definition video onto dual-layer standard DVD-9 discs. In spite of this decision, however, the DVD Forum's Steering Committee announced in April that it was pursuing its own blue-laser high-definition video solution. In August, Toshiba and NEC announced their competing standard,
10100-399: Was threatened by the advent of digital home video was the tradition of releasing a movie to cinemas and then for general rental or sale later in some countries than in others. This practice was historically common because before the advent of digital cinema , releasing a movie at the same time worldwide used to be prohibitively expensive. Most importantly, manufacturing a release print of
10201-535: Was underway to create a 1 TB Blu-ray Disc. At CES 2009, Panasonic unveiled the DMP-B15, the first portable Blu-ray Disc player, and Sharp introduced the LC-BD60U and LC-BD80U series, the first LCD HDTVs with integrated Blu-ray Disc players. Sharp also announced that it would sell HDTVs with integrated Blu-ray Disc recorders in the United States by the end of 2009. Set-top box recorders were not being sold in
