    La continua evoluzione dell'elettronica e della tecnologia di visualizzazione aumenta sempre più la definizione, la superficie visualizzabile e le dimensioni stesse degli schermi. Fino al 2003, la maggior parte dei monitor aveva un rapporto d'aspetto di 4:3 e qualcuno di 5:4. Dal 2003 al 2006 si sono resi disponibili vari monitor con un rapporto di risoluzione tipicamente di 16:10 (e talvolta 16:9), inizialmente sui laptop e successivamente sui monitor per PC. Con questi rapporti dimensionali ci si avvicina di più ai formati tv e cinematografici, utili per il montaggio video, la computergrafica e i videogiochi, si aiutano inoltre le attività di wordprocessing e DTP, che ne hanno tratto beneficio potendo visualizzare l'equivalente di due pagine A4affiancate. La Video Electronics Standards Association (VESA) ha definito diversi standard video mentre quelli ergonomici sono definiti dal TCO.

    Una risoluzione di 1024×600 ad esempio indica che l'immagine sul monitor è formata da 1024 colonne e 600 righe ed è pertanto caratterizzata da un rapporto d'aspetto di circa 1,707:1. Nel caso dei monitor LCD o al plasmal'immagine verrà riadattata alla risoluzione dello schermo perché caratterizzata da una risoluzione fissa che costringe a ridimensionare tutte le immagini o a ricevere direttamente quel solo formato. Nel caso di un monitor a tubo catodico, se l'immagine rientra nell'intervallo di risoluzione minima e massima verrà proiettata senza alcuna alterazione, mentre nel caso il monitor riceva immagini troppo grandi il monitor non visualizzerà alcuna immagine. Secondo il report della società Net Analytics, al 2008 la tradizionale risoluzione dei siti web a 800×600 risultava in larga misura superata dalle seguenti scelte degli sviluppatori: 1024×768 (37%), 1280×960 (20%), 1280×1024 (13%). La scelta della risoluzione è influenzata dall'ampiezza del monitor e dall'eventuale riduzi...

    Nella tabella, qui sotto riportata, troviamo le risoluzioni video più comuni nei PC che si sono evoluti dall'originale IBM PC, più alcune che sono supportate da altri tipi di computer come ad esempio i computer Apple. La Video Electronics Standards Association (VESA) ha curato le specifiche di molti di questi standard. Tuttavia, val la pena far notare che dal 2014-15 si è vista un'evoluzione oltre i 2k verso risoluzioni "personalizzate" con misure inconsuete e non facilmente classificabili, più vicine alle esigenze costruttive e dimensionali del prodotto che delle consuetudini e degli standard. Vedi il Microsoft Surface 4 (2736x1824), i MacBook Pro (2880x1800) o il Microsoft Surface Studio(4500 x 3000).

    Nella tabella qui sotto riportata troviamo le risoluzioni video più comuni nei televisori e nei videoproiettori. Nella tabella seguente 60 Hz o 60 FPS sono un'approssimazione. Il valore preciso è 60 1000 1001 {\\displaystyle 60{\\frac {1000}{1001}}} ossia circa 59,94.

    The Oxford English Dictionary comments that, "In 1995, rival manufacturers of the product initially named digital video disc agreed that, in order to emphasize the flexibility of the format for multimedia applications, the preferred abbreviation DVD would be understood to denote digital versatile disc." The OED also states that in 1995, "The companies said the official name of the format will simply be DVD. Toshibahad been using the name 'digital video disc', but that was switched to 'digital versatile disc' after computer companies complained that it left out their applications." "Digital versatile disc" is the explanation provided in a DVD Forum Primer from 2000and in the DVD Forum's mission statement.

    Development

    There were several formats developed for recording video on optical discs before the DVD. Optical recording technology was invented by David Paul Gregg and James Russell in 1963 and first patented in 1968. A consumer optical disc data format known as the LaserDisc was developed in the United States, and first came to market in Atlanta, Georgia in December 1978. It used much larger discs than the later formats. Due to the high cost of players and discs, consumer adoption of the LaserDisc was v...

    Adoption

    Movie and home entertainment distributors adopted the DVD format to replace the ubiquitous VHS tape as the primary consumer video distribution format. They embraced DVD as it produced higher quality video and sound, provided superior data lifespan, and could be interactive.[citation needed] Interactivity on LaserDiscs had proven desirable to consumers, especially collectors. When LaserDisc prices dropped from approximately $100 per disc to $20 per disc at retail, this luxury feature became av...

    The DVD specifications created and updated by the DVD Forum are published as so-called DVD Books (e.g. DVD-ROM Book, DVD-Audio Book, DVD-Video Book, DVD-R Book, DVD-RW Book, DVD-RAM Book, DVD-AR (Audio Recording) Book, DVD-VR (Video Recording) Book, etc.). DVD discs are made up of two discs; normally one is blank, and the other contains data. Each disc is 0.6 mm thick, and are glued together to form a DVD disc. The gluing process must be done carefully to make the disc as flat as possible to avoid both birefringenceand "disc tilt", which is when the disc is not perfectly flat, preventing it from being read. Some specifications for mechanical, physical and optical characteristics of DVD optical discs can be downloaded as freely available standards from the ISO website. There are also equivalent European Computer Manufacturers Association (Ecma) standards for some of these specifications, such as Ecma-267 for DVD-ROMs. Also, the DVD+RW Alliance publishes competing recordable DVD speci...

    HP initially developed recordable DVD media from the need to store data for backup and transport.[failed verification] DVD recordables are now also used for consumer audio and video recording. Three formats were developed: DVD-R/RW, DVD+R/RW (plus), and DVD-RAM. DVD-R is available in two formats, General (650 nm) and Authoring (635 nm), where Authoring discs may be recorded with CSSencrypted video content but General discs may not. Although most current DVD writers can write in both the DVD+R/RW and DVD-R/RW formats (usually denoted by "DVD±RW" or the existence of both the DVD Forumlogo and the DVD+RW Alliance logo), the "plus" and the "dash" formats use different writing specifications. Most DVD hardware plays both kinds of discs, though older models can have trouble with the "plus" variants. Some early DVD players would cause damage to DVD±R/RW/DL when attempting to read them.[citation needed] The form of the spiral groove that makes up the structure of a recordable DVD encodes un...

    The basic types of DVD (12 cm diameter, single-sided or homogeneous double-sided) are referred to by a rough approximation of their capacity in gigabytes. In draft versions of the specification, DVD-5 indeed held five gigabytes, but some parameters were changed later on as explained above, so the capacity decreased. Other formats, those with 8 cm diameter and hybrid variants, acquired similar numeric names with even larger deviation. The 12 cm type is a standard DVD, and the 8 cm variety is known as a MiniDVD. These are the same sizes as a standard CD and a mini-CD, respectively. The capacity by surface area (MiB/cm2) varies from 6.92 MiB/cm2 in the DVD-1 to 18.0 MB/cm2 in the DVD-18.[clarification needed] Each DVD sector contains 2,418 bytes of data, 2,048 bytes of which are user data. There is a small difference in storage space between + and -(hyphen) formats:

    DVD drives are devices that can read DVD discs on a computer. DVD players are a particular type of devices that do not require a computer to work, and can read DVD-Video and DVD-Audiodiscs.

    DVD-Video is a standard for distributing video/audio content on DVD media. The format went on sale in Japan on November 1, 1996, in the United States on March 24, 1997 to line up with the 69th Academy Awards that day; in Canada, Central America, and Indonesia later in 1997, and in Europe, Asia, Australia, and Africa in 1998. DVD-Video became the dominant form of home video distribution in Japan when it first went on sale on November 1, 1996, but it shared the market for home video distribution in the United States until June 15, 2003, when weekly DVD-Video in the United States rentals began outnumbering weekly VHS cassette rentals.DVD-Video is still the dominant form of home video distribution worldwide except for in Japan where it was surpassed by Blu-ray Discwhen Blu-ray first went on sale in Japan on March 31, 2006.

    DVD-Audio is a format for delivering high fidelity audio content on a DVD. It offers many channel configuration options (from mono to 5.1 surround sound) at various sampling frequencies (up to 24-bits/192 kHz versus CDDA's 16-bits/44.1 kHz). Compared with the CD format, the much higher-capacity DVD format enables the inclusion of considerably more music (with respect to total running time and quantity of songs) or far higher audio quality (reflected by higher sampling rates, greater sample resolution and additional channels for spatial soundreproduction). DVD-Audio briefly formed a niche market, probably due to the very sort of format war with rival standard SACD that DVD-Videoavoided.

    In 2006, two new formats called HD DVD and Blu-ray Disc were released as the successor to DVD. HD DVD competed unsuccessfully with Blu-ray Disc in the format war of 2006–2008. A dual layer HD DVD can store up to 30 GB and a dual layer Blu-ray disc can hold up to 50 GB. However, unlike previous format changes, e.g., vinyl to Compact Disc or VHS videotape to DVD, there is no immediate indication that production of the standard DVD will gradually wind down, as they still dominate, with around 75% of video sales and approximately one billion DVD player sales worldwide as of April 2011. In fact, experts claim that the DVD will remain the dominant medium for at least another five years as Blu-ray technology is still in its introductory phase, write and read speeds being poor and necessary hardware being expensive and not readily available. Consumers initially were also slow to adopt Blu-ray due to the cost. By 2009, 85% of stores were selling Blu-ray Discs. A high-definition television an...

    Longevity of a storage medium is measured by how long the data remains readable, assuming compatible devices exist that can read it: that is, how long the disc can be stored until data is lost. Numerous factors affect longevity: composition and quality of the media (recording and substrate layers), humidity and light storage conditions, the quality of the initial recording (which is sometimes a matter of mutual compatibility of media and recorder), etc. According to NIST, "[a] temperature of 64.4 °F (18 °C) and 40% RH [Relative Humidity] would be considered suitable for long-term storage. A lower temperature and RH is recommended for extended-term storage." According to the Optical Storage Technology Association(OSTA), "Manufacturers claim lifespans ranging from 30 to 100 years for DVD, DVD-R and DVD+R discs and up to 30 years for DVD-RW, DVD+RW and DVD-RAM." According to a NIST/LoC research project conducted in 2005–2007 using accelerated life testing, "There were fifteen DVD produ...
