CD-ROM, CD-R, CD-RW, and DVD-ROM Drives) Are the Hardware Devices That Read Computer Data from Disks
A Brief History of CD/DVD The first disc that could be written and read by optical means (using light as a medium) was developed by James T. Russell. In the late 1960s, Russell created a system that recorded, stored, and played audio/video data using light rather than the traditional contact methods, which could easily damage the disks during playback. Russell developed a photosensitive disc that stored data as 1 micron-wide dots of light and dark. The dots were read by a laser, converted to an electrical signal, and then to audio or visual display for playback. Russell's own company manufactured the first disc player in 1980, although the technology never reached the marketplace until Philips and Sony developed the technology. In late 1982, Philips and Sony released the first of the compact disc (CD) formats, which they then called CD-DA (digital audio). In the years since, format has followed format as the original companies and other industry members developed more adaptations of the original specifications. Digital Versatile disc (DVD) had its beginning in 1994, when two formats, Super disc (SD) and Multimedia CD (MMCD) were introduced. Promoters of the competing technologies failed to reach an agreement on a single standard until 1996, when DVD was selected as a convergence format. DVD has, in the few years since, grown to include variations that do anything that CD does, and more efficiently. Standardization and compatibility issues aside, DVD is well-placed to supplant CD. Magnetic vs Optical Media Optical media are storage media that hold information in digital form and that are written and read by a laser; these media include all the various CD and DVD variations, as well as optical jukeboxes and autochangers. -

Introduction to DVD Carol Cini, U.S
Proceedings of the 8th Annual Federal Depository Library Conference April 12 - 15, 1999 Introduction to DVD Carol Cini, U.S. Government Printing Office Washington, DC DVD started out standing for Digital Video Disc, then Digital Versatile Disc, and now it’s just plain old DVD. It is essentially a bigger and faster CD that is being promoted for entertainment purposes (movies) and some computer applications. It will eventually replace audio CDs, VHS and Beta tapes, laserdiscs, CD-ROMs, and video game cartridges as more hardware and software manufacturers support this new technology. DVDs and CDs look alike. A CD is a single solid injected molded piece of carbonate plastic that has a layer of metal to reflect data to a laser reader and coat of clear laminate for protection. DVD is the same size as a CD but consists of two solid injected molded pieces of plastic bonded together. Like CDs, DVDs have a metalized layer (requires special metalization process) and are coated with clear laminate. Unlike CD's, DVD's can have two layers per side and have 4 times as many "pits" and "lands" as a CD. There are various types of DVD, including DVD-ROM, DVD-Video, DVD-Audio, DVD-R, and DVD-RAM. The specifications for these DVD's are as follows: for prerecorded DVD's; Book A - DVD-ROM, Book B - DVD-Video, and Book C- DVD-Audio. For recordable DVD's, there is Book D - DVD-R, Book E - DVD-RAM. The official DVD specification books are available from Toshiba after signing a nondisclosure agreement and paying a $5,000 fee. -
HDTV Vs HD Ready
Skylink Engineering Sas - Partita Iva: 02568530964 Sede Legale: Largo Esterle, 4 Monza (MI) - Magazzino e Uffici: Via XXIV Maggio, 2–20035 Lissone (MI) SETTORE ANTENNE Numeri telefonici: Tel. 039/2457492 – Fax 039/2457591 E-Mail: [email protected] - Sito WEB: www.skylinksas.com HDTV vs HD Ready Lo scorso 20 Marzo l’EICTA (l’European Information & Communications Technology Industry Association) ha introdotto un nuovo logo che presuppone una nuova certificazione e quindi delle nuove specifiche da rispettare. Stiamo parlando dell’HDTV . Tutti sappiamo cos'è un HDTV (High Definition Television), ma non tutti sanno che un HDTV per essere considerato tale deve rispettare dei requisiti da oggi più precisi e rigorosi. Infatti non poca è stata finora la confusione che questo “appellativo” ha generato nella testa dei consumatori meno esperti. Le case produttrici dal canto loro non si sono poi tanto impegnate a chiarire eventuali dubbi: anzi molto spesso sono state le principali attrici in questo palcoscenico sovrastato dal caos totale. In sostanza il mercato dell’HDTV era (ed ancora lo è!) diventato una selva “oscura” (per dirla alla Dante), con i produttori che si davano battaglia a suon di “HD Ready e HDTV”. Ci ha pensato l’EICTA lo scorso 19 Gennaio 2005 a fare un po' di chiarezza e a riportare un po di ordine, in un mercato che ormai andava per conto suo a discapito del povero consumatore, introducendo il marchio HD READY , fino ad allora abusato da produttori e commercianti. L’associazione ha dapprima spiegato cosa si deve intendere per alta definizione e, successivamente, ha elencato quelle che sono le caratteristiche minime che un display (Plasma, lcd, Retroproiettore e Videoproiettore) deve avere per poter essere fregiato del logo HD READY. -

Blu -Ray Disc 2010 CHAPTER: - 1 INTRODUCTION 1 | P a g e Blu -Ray Disc 2010 Introduction Blu-ray Disc (official abbreviation BD) is a high definition media format designed to supersede the DVD format. The format defines as its standard physical media a 5-inch (same as DVDs and CDs), 25 GB per-layer optical disc, being dual layer discs (50 GB) the norm for feature-length video discs, and the addition of more layers left open as a future possibility. The name Blu-ray Disc refers to the "blue laser" used to read the disc, which allows for five times more storage than on a DVD. Blu-ray Disc was developed by the Blu-ray Disc Association, a group representing makers of consumer electronics, computer hardware, and motion pictures. As of June 2009, more than 1,500 Blu-ray Disc titles were available in Australia and the United Kingdom, with 2,500 in the United States and Canada. In Japan as of July 2010 more than 3,300 titles were released. During the high definition optical disc format war, Blu-ray Disc competed with the HD DVD format. Toshiba, the main company that supported HD DVD, conceded in February 2008, releasing their own Blu-ray Disc player in late 2009. 2 | P a g e Blu -Ray Disc 2010 CHAPTER: 2 HISTORY 3 | P a g e Blu -Ray Disc 2010 History A blank rewritable Blu-ray Disc (BD-RE). Commercial HDTV sets began to appear in the consumer market around 1998, but there was no commonly accepted, inexpensive way to record or play HD content. -
What Is a DVD? Technical Considerations
NCTE Advice Sheet – DVDs Advice Sheet 6 DVDs Leaving Certificate students are using a DVD featuring Shakespearean plays to quickly progress through scenes in each play. They are doing so in order to compare and contrast specific themes. What is a DVD? DVD is an acronym for Digital Versatile Disc. It is very similar in appearance to a compact disc, but has considerably more storage capacity. The commonly available DVD holds 4.7GB of information on one layer, or enough for a 2-hour movie, audio or other digital information. Dual Layer recording allows discs to store significantly more data, up to 8.5GB per disc, compared with 4.7 GB for single-layer discs. Using MPEG-2 video compression — the same system that will be used for digital TV, satellite and cable transmissions — it is quite possible to fit a full-length movie onto one side of a DVD. In a computing context, however, DVD means more than just movies. The unprecedented storage capacity provided by DVD lets application vendors fit multiple CD titles (phone databases, map programs, encyclopedias’) on a single disc, making them more convenient to use. Developers of edutainment (education/entertainment) and reference titles are also able to use video and audio clips more liberally in their products. Technical Considerations To play a DVD disc, a DVD player is required. They fall into two categories: (1) home DVD players that play movies, and (2) DVD drives in PCs that read DVDs containing digital information of any sort, e.g., audio, video, multimedia content, etc. Home DVD Players DVD home players are primarily focused on playing video and films • DVD players allow users to change languages at the switch of a button — normally the choice is English, French or Spanish. -

EXAMPLES AND APPLICATIONS HDTV High Definition Television (HDTV) is expected to replace standard television in the coming years. Compared to the PAL and SECAM formats, HDTV offers up to five times more detail. The common HDTV formats are 720p, 1080i and 1080p. The 1080p format with a resolution of 1920x1080 pixels/lines, delivers a picture with a resolution and picture size five times greater than the current PAL format with 720x576 pixels/lines. HDTV offers the viewer more detail. However, as picture quality improves, the amount of storage required to record such a high-resolution television signal without loss of quality also increases. Due to the large amount of television signal data, viewers can only record approximately 20 minutes of programming in HDTV quality on a conventional DVD. The Blu-ray Disc offers viewers sufficient storage capacity to record their favourite TV shows in HDTV quality without any loss of data. 4 bluray_brochure_AU.qxd 8/9/06 4:21 PM Page 5 Data Storage More and more businesses are investing in backup systems capable of storing vast amounts of data. -
