8680-419: 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

8804-510: The channel such as business or person managing their online presence Earned media denotes public relations media channels like television, newspapers, blogs, or video sites that do not require direct payment or control by marketers but are included because viewers, readers, or users are interested in them. Free media is essentially online word of mouth, typically in "viral" trends, mentions, shares, retweets, reviews, recommendations, or content from third-party websites. When one's product or service

8928-460: The close partnership we have shared with Toshiba, it is time to turn our focus to releasing new and catalog titles on Blu-ray Disc." 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

9052-570: The commercial landscape. While Android and iOS both dominate the smartphone market. A study By Gartner found that in 2016 about 88% of the worldwide smartphones were Android while iOS had a market share of about 12%. About 85% of the mobile market revenue came from mobile games. The impact of the digital revolution can also be assessed by exploring the amount of worldwide mobile smart device users there are. This can be split into 2 categories; smart phone users and smart tablet users. Worldwide there are currently 2.32 billion smartphone users across

9176-469: The content in question when there are court orders and/or allegations of illegal use of the content on their site. As a result, YouTube has and continues to develop more policies and standards that go far past what the DMCA requires. YouTube has also created an algorithm which continuously scans their cite to make sure all content follows all policies. One digital media platform known to have copyright concerns

9300-405: The creation of this memex would be the work of scientists after World War II. Though the essay predated digital computers by several years, "As We May Think" anticipated the potential social and intellectual benefits of digital media and provided the conceptual framework for digital scholarship , the World Wide Web , wikis and even social media . It was recognized as a significant work even at

9424-565: The current copyright and intellectual property laws. The ease of creating, modifying, and sharing digital media can influence copyright enforcement challenging and many copyright laws are widely seen as outdated. Under current copyright law, common Internet memes are generally illegal to share in many countries. Legal rights can be unclear for many common Internet activities. These include posting pictures from someone else's social media account, writing fanfiction , or covering and/or using popular songs in content such as YouTube videos. During

9548-460: The data is stored lies under a 0.1  mm protective layer and on top of a 1.1 mm substrate made of polycarbonate plastic, compared to 0.6 mm on either side on DVDs. 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

9672-471: The development of millions of software applications. Most of these apps are able to generate income via in app advertising. Gross revenue for 2020 is projected to be about $ 189 million. Compared with print media , the mass media , and other analog technologies, digital media are easy to copy, store, share and modify. This quality of digital media has led to significant changes in many industries, especially journalism, publishing, education, entertainment, and

9796-417: The discs to 250 GB. However, it noted the major obstacle was that current read/write technology did not allow additional layers. 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

9920-403: The feature, only a description for what it does. The feature may be activated by default, as is the case in the disc writing utility growisofs . Deactivating write verification may be desirable to save time when mass-producing physical copies of data, since errors are unlikely to occur on physically undamaged media. The quality and data integrity of optical media can be determined by measuring

10044-409: The first prototype discs coming four years later. On January 7, 2013, Sony announced that it would release "Mastered in 4K" Blu-ray Disc titles sourced at 4K and encoded at 1080p. "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 a task force

10168-457: 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 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

10292-573: 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

10416-430: 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 the first three quarters of 2007, BD outsold HD DVD by about two to one. At CES 2007 , Warner proposed Total Hi Def —a hybrid disc containing Blu-ray on one side and HD DVD on

10540-579: The hard coating, given that, according to the Blu-ray Disc Association, they offer the best tradeoff between scratch resistance, optical properties, and productivity. 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. The table shows

10664-632: The initial specification for storing movies on Blu-ray discs defined a maximum resolution of 1080p ( 1920 × 1080 pixels) at up to 24 progressive or 29.97 interlaced frames per second . Revisions to 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

10788-547: The internet becomes more and more prevalent, more companies are beginning to distribute content through internet only means. Indeed, young people today are increasingly likely to use TikTok over Google, television or newspapers for their news. With the loss of viewers, there is a loss of revenue but not as bad as what would be expected. As of 2024 there has also been a wave of those considered too controversial by main-stream media moving over to online platforms such as X (formerly Twitter) to keep spreading their messages. One instance

10912-439: The larger issues that have occurred concerning digital media copyright. The piracy of digital media, such as film and television, directly impacts the copyright party (the owner of the copyright). This action can impact the "health" of the digital media industry. Piracy directly breaks the laws and morals of copyright. Along with piracy, digital media has contributed to the ability to spread false information or fake news . Due to

11036-668: The last decade, the concepts of fair use and copyright have been applied to different types of online media. Copyright challenges are spreading to all parts of digital media. Content creators on platforms such as YouTube follow guidelines set by copyright, IP laws, and the platform's copyright requirements. If these guidelines are not followed, the content may get demonetized, deleted, or sued. The situation can also occur when creators accidentally use audio tracks or background scenes that are under copyright. To avoid or resolve some of these issues, content creators can voluntarily adopt open , or copyleft licenses or they can release their work to

11160-448: The main trail or joining it by a side trail to a particular item. When it becomes evident that the elastic properties of available materials had a great deal to do with the bow, he branches off on a side trail which takes him through textbooks on elasticity and tables of physical constants. He inserts a page of longhand analysis of his own. Thus he builds a trail of his interest through the maze of materials available to him. Bush hoped that

11284-412: The maximum exploitable drive speed is 288  Mbit/s or 36  MB/s (also called 8× speed). A USB 3.0 interface (with proper cabling) does not have this limitation, nor do even the oldest version of Serial ATA (SATA, 150 MB/s) nor the latest Parallel ATA (133 MB/s) standards. Internal Blu-ray drives that are integrated into a computer (as opposed to physically separate and connected via

Other old machine readable media include instructions for pianolas and weaving machines. It

11532-402: The most popular days for papers, Sunday, has seen a 9% circulation decrease the lowest since 1945. In journalism, digital media and citizen journalism have led to the loss of thousands of jobs in print media and the bankruptcy of many major newspapers. But the rise of digital journalism has also created thousands of new jobs and specializations. E-books and self-publishing are changing

11656-401: The music business. The overall effect of these changes is so far-reaching that it is difficult to quantify. For example, in movie-making, the transition from analog film cameras to digital cameras is nearly complete. The transition has economic benefits to Hollywood, making distribution easier and making it possible to add high-quality digital effects to films. At the same time, it has affected

11780-473: 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,

11904-482: 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

12028-420: 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

12152-514: 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, 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

12276-423: 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

12400-440: The platform. Paid media refers to promotional channels that marketers pay to use, including traditional media (e.g., television, radio, print, or outdoor advertising), online and digital media (e.g., paid search ads, web and social media display ads, mobile ads, or email marketing). This model compels businesses to develop sponsored media then pay social media platforms like Instagram for the right to show such media to customers in

12524-413: The platforms' newsfeeds. These customers become exposed to paid media, sometimes referred to as promoted or sponsored posts. Owned media refers to digital assets and channels that a company or individual controls and manages. This includes websites, social media profiles for example Facebook etc., blogs, and any other content platforms own and operated by the entity. Entity means the owner or controller of

12648-518: The problem of error in calculations. Between 1822 and 1823, the mathematician Ada Lovelace wrote the first instructions for calculating numbers on Babbage engines. Lovelace's instructions are now believed to be the first computer program. Although the machines were designed to perform analysis tasks, Lovelace anticipated the possible social impact of computers and program writing. "For in the distribution and combination of truths and formulas of analysis, which may become easier and more quickly subjected to

12772-551: 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

12896-721: 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,

13020-619: The rise of digital computers . Digital computers use binary code and Boolean logic to store and process information, allowing one machine in one configuration to perform many different tasks. The first modern, programmable, digital computers, the Manchester Mark 1 and the EDSAC , were independently invented between 1948 and 1949. Though different in many ways from modern computers, these machines had digital software controlling their logical operations . They were encoded in binary ,

13144-408: 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

13268-517: The same size as DVDs and CDs . Conventional (or "pre-BD-XL") Blu-ray discs contain 25  GB per layer, with dual-layer discs (50 GB) being the industry standard for feature-length video discs. Triple-layer discs (100 GB) and quadruple-layer discs (128 GB) are available for BD-XL re-writer drives. While the DVD-Video specification has a maximum resolution of 480p ( NTSC , 720 × 480 pixels) or 576p ( PAL , 720 × 576 pixels),

13392-405: The scope of where digital magazines can be published; smartphones are an example. Thanks to the improvements in tablets and other personal electronic devices, digital magazines have become much more readable and enticing through the use of graphic art. The evolution of online magazines began to focus on becoming more of a social media and entertainment platform. Online piracy has become one of

13516-580: 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

13640-455: The skirmishes of the Crusades. He has dozens of possibly pertinent books and articles in his memex. First, he runs through an encyclopedia, finds an interesting but sketchy article, and leaves it projected. Next, in history, he finds another pertinent item and ties the two together. Thus he goes, building a trail of many items. Occasionally he inserts a comment of his own, either linking it into

13764-414: 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,

13888-441: The start of a new era in industrial history, called the Information Age , perhaps leading to a paperless society in which all media are produced and consumed on computers. However, challenges to a digital transition remain, including outdated copyright laws, censorship , the digital divide , and the spectre of a digital dark age , in which older media becomes inaccessible to new or upgraded information systems. Digital media has

14012-403: 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

14136-459: The time of its publication. Since the 1960s, computing power and storage capacity have increased exponentially, largely as a result of MOSFET scaling which enables MOS transistor counts to increase at a rapid pace predicted by Moore's law . Personal computers and smartphones put the ability to access, modify, store and share digital media in the hands of billions of people. Many electronic devices, from digital cameras to drones have

14260-547: The way libraries are used and their role in society. Every major media, communications and academic endeavor is facing a period of transition and uncertainty related to digital media. Often time the magazine or publisher have a Digital edition which can be referred to an electronic formatted version identical to the print version. There is a huge benefit to the publisher and cost, as half of traditional publishers' costs come from production, including raw materials, technical processing, and distribution. Since 2004, there has been

14384-460: The wide range of literacy and communications skills necessary to use it effectively, have deepened the digital divide between those who have access to digital media and those who do not. The rising of digital media has made the consumer's audio collection more precise and personalized. It is no longer necessary to purchase an entire album if the consumer is ultimately interested in only a few audio files. The rise of streaming services has led to

14508-492: The widespread use of digital media, fake news can receive more notoriety. This notoriety enhances the negative effects fake news creates. As a result, people's health and well-being can directly be affected. Nanometre The nanometre (international spelling as used by the International Bureau of Weights and Measures ; SI symbol: nm ), or nanometer ( American spelling ), is a unit of length in

14632-474: The world. This figure is to exceed 2.87 billion by 2020. Smart tablet users reached a total of 1 billion in 2015, 15% of the world's population. The statistics evidence the impact of digital media communications today. What is also of relevance is the fact that the number of smart device users is rising rapidly yet the amount of functional uses increase daily. A smartphone or tablet can be used for hundreds of daily needs. There are currently over 1 million apps on

14756-582: The years have a multi camera set up as we would see on TV. Many of these creators also creating their own digital companies as their personalities grow. Personal devices have also seen an increase over the years. Over 1.5 billion users of tablets exist in this world right now and that is expected to slowly grow About 20% of people in the world regularly watch their content using tablets in 2018 User-generated content raises issues of privacy, credibility, civility and compensation for cultural, intellectual and artistic contributions. The spread of digital media, and

14880-507: 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),

15004-528: 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

15128-470: 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

15252-478: Was created three months prior to conduct a study concerning an extension to the Blu-ray Disc specification that would add the ability to contain 4K UHD video. On August 5, 2015, the BDA announced it would commence licensing the Ultra HD Blu-ray video format starting on August 24, 2015. The Ultra HD Blu-ray format delivered support for high dynamic range video that significantly expanded the range between

15376-534: 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
