Philips and Sony proposed the Compact Disc Digital Audio standard (CD-DA) which was coded in the so-called Red Book [Philips and Sony Corporation, 1991]. The development of this technique revolutionized the audio world by introducing truly digital technology for the first time. It was in the year 1982 that Philips and Sony launched the first players and discs on the market. The CD became the music carrier of choice by 1991, when sales exceeded those of audio-cassettes. Another widely available optical disc
Choosing the Best Sound Format for Production There are many issues facing an audio professional who is considering getting into surround production, either for music, film, DVD, Internet, or multi-media. Whether you are recording, mixing, editing, or mastering, there is a lot of information that you need to be comfortable with before you can succeed in surround sound. Although this collection is a good start, it is by no means an exhaustive list or in-depth manual. Hopefully it will give you a

Information can be stored on both sides of the disk unlike CD ROM which can only store information on one side. DVD drives operate at different speeds which means the speed at which data can be retrieved varies. The quality of the laser also affects the performance. DVD ROMs often hold information like movies in an encrypted format. This is
BD and DVD both have pits and bumps. The difference between the two is that the BD pits and bumps are smaller and packed closer together. A blue laser is used to read the BD. The BD has spiral tracks running from the center of the disc out to the edges. The information is stored in these tracks in the form of audio and video. The blue laser used to read this information has a wavelength of approximately 405 nanometers and must be much more accurate than that of a DVD as the pits and bumps are smaller
The DVD Revolution Specific Purpose: To inform my audience about the features and advantages of DVD video. Central Idea: The DVD video format has superior audio and visual quality to VHS, as well as more special features, which is why it should eventually occupy the place of the VCR in American households. Introduction I’d like to start things out by taking a survey. How many of you remember having a CD player in your house fifteen years ago? Not very many of you, I see. Of course, we all have
companies and artists sell to the public. However, if “pirates” are selling illegal copies of the media, the companies do not make any money. For example, Feng Xiaogang, a Chinese director, said in an article on CNN.com, “We estimate that one pirated DVD is watched by five people and there are roughly one million pirated copies of our film. One million copies times five people times $2.10 per tickets -- that's more than twelve million Yuan in box office loss” (FlorCruz 2002). Piracy costs people

This opinion was reinforced when the government began to have large institutions built to house all the people described as ‘mental deficiency’: ‘idiots’, ‘imbeciles’, ‘feeble-minded persons’ and ‘moral imbeciles’.

Communication is an essential part of daily life for everyone but for people who have learning difficulties or impairments like those in Lennox Castle it is especially important. This is why it is imperative all workers
differences between the average home Video Cassette Recorder (VCR) and the recently developed Digital Video Disc (DVD) system. These two home entertainment components have very clear differences. It is important for consumers to carefully consider each of these concerns before deciding on the home entertainment component that is right for them.When considering the purchase of a home VCR or DVD system, consumers should carefully examine the varying costs of the two components. If cost is a concern, consumers
it, the now ubiquitous DVD. The acronym “DVD” originally stood for Digital Video Disc, but as this versatile technology found more and more uses in non-video applications, it has come to be known by many as the Digital Versatile Disc. Officially, the members of the DVD Forum (maintained by Toshiba) never came to a decision on the matter, so the name of the format remains “DVD,” and the meaning of the “V” remains ambiguous. But despite the confusion over the acronym, the DVD has taken the world by
The Physics of CDs and DVDs Everywhere you look now days, you see or interact with CDs or DVDs; whether it is in the car, at work, or at home for pleasure, you deal with these modern marvels. Whatever the use, CD has become a reliable medium in which to distribute information, in a reliable way. The cost of a CD is very inexpensive, making it a popular choice by companies trying to advertise, or teach you about something. American On Line (AOL) is one example of companies who have chose this reliable
together introduced the first color videodisc prototype in 1972. Sony teamed up with Philips on the creation of the compact disc, and together they were able to develop a standard, universal compact disc to hold audio information. The two companies officially announced the Digital-Audio disc in 1980. In 1982, the compact disc was introduced to the public in Europe and Japan. Later, in 1983, it was introduced in the United States (Future). Compact Discs are flat and circular, with a diameter
The Technological Need for Holographic Data Storage Digital technology has become the latest byword in entertainment and computers. Records and analog cassette tapes have been supplanted with Compact Discs, and now VCRs are being challenged by Digital Video Discs. Multimedia applications such as these consume enormous amounts of storage space, and are challenging the limits of today's storage devices. Many solutions are being put forth in an attempt to keep pace with the growth in demand for
N.V. Philips (Netherlands) and Matsushita Electric (Japan) are among the largest consumer electronics companies in the world. Their success was based on two contrasting strategies – diversification of worldwide portfolio and local responsiveness for Philips, and high centralization and mass production for Matsushita. Royal Philips Electronics of the Netherlands began as a small light-bulb factory in Holland, and by the turn of the century, was one of the largest producers in Europe. One-product

Instead of using a method established by other video markets “to attract customers to a retail location, Netflix offered home delivery of DVDs through the mail” which eventually led to a booming business towards streaming forms of entertainment (Shih, Kaufman, & Spinola, 2009, p. 3). Today, Netflix exists along with several competitors; however, offers the most streaming content available

As I sat in front of my computer downloading my favorite song from Napster, I started to think about how hard it must have been to write a song so sublime with the way the words flow from one another, and how talented one must be to do so. I started to think how hard people work on their music for themselves and their fans, and how their fans don’t realize what they are doing every time they download a song off the internet. What they don’t realize is that it is messing over the people who worked
DVD sales have declined causing a current problem for Sony Corporations subsidiary Sony Pictures Entertainment. Sony Pictures Entertainment Inc. has seen a severe decline in revenue in the past recent months. DVD sales have declined to a level of severe concern, and as such left financial analysts and specialists in the industry deeply worried. We have taken to the field and conducted a number of interviews to decipher the basis of the rationale behind lack of DVD sales. Through the course of the
Sometimes I really miss video stores; the experience of walking into a huge store filled with shelves of films, TV shows and video games was lost in the upheaval of modern technology taking the lead in entertainment. Now you can simply walk up to a Redbox and choose from a semi limited selection of films and games at a far lower price, but like video stores there is a late fee if your item is not returned on time. Though if you are looking for a larger catalogue there’s always Netflix who’s fully
automated DVDs, Blu-ray Discs and video games rentals, was founded by McDonald’s Corporation. Customers are able to rent movies or video games at an affordable price via a vending machine. The idea was to drive more traffic to McDonald’s and added convenience to customers. In 2002, the company tested two concepts by placing fully automated convenience store kiosks (vending-like machine that sells anything from milk to shampoo) and DVD rental kiosks in the Washington D.C. area. The DVD kiosks succeeded
