In mass communication , digital media is any communication media that operates in conjunction with various encoded machine-readable data formats. Digital content can be created, viewed, distributed, modified, listened to, and preserved on a digital electronic device, including digital data storage media (in contrast to analog electronic media ) and digital broadcasting . Digital is defined as any data represented by a series of digits, and media refers to methods of broadcasting or communicating this information. Together, digital media refers to mediums of digitized information broadcast through a screen and/or a speaker. This also includes text, audio, video, and graphics that are transmitted over the internet for viewing or listening to on the internet.

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and sharing digital media can influence copyright enforcement challenging and many copyright laws are widely seen as outdated.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
10168-453: 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
10292-566: 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
10540-569: 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.

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
11780-469: 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,
11904-479: 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
12152-511: 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

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
12772-545: 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,
13020-608: 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 ,

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),
15004-479: 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
