LaserDisc
LaserDisc (LD) is a home video format and the first commercial optical disc storage medium. It was developed by Philips, Pioneer Corporation, Pioneer, and the movie studio MCA Inc., MCA. The format was initially marketed in the United States in 1978 under the name DiscoVision, a brand used by MCA. As Pioneer took a greater role in its development and promotion, the format was rebranded LaserVision. While the LaserDisc brand originally referred specifically to Pioneer's line of players, the term gradually came to be used generically to refer to the format as a whole, making it a genericized trademark. The discs typically have a diameter of , similar in size to the phonograph record. Unlike most later optical disc formats, LaserDisc is not fully Digital data, digital; it stores an analog video signal. Many titles featured Compact Disc Digital Audio, CD-quality digital audio, and LaserDisc was the first home video format to support surround sound. Its 425 to 440 horizontal lin ...

Optical Recording
The history of optical recording can be divided into a few number of distinct major contributions. The pioneers of optical recording worked mostly independently, and their solutions to the many technical challenges have very distinctive features, such as *reflective disc (Compaan and Kramer) *transparent disc (Gregg) *floppy disc (Russell) *rigid disc (Compaan and Kramer) *focused laser beam for read-out through transparent substrate (Compaan and Kramer). Gregg 1958 Laserdisc technology, using a transparent disc, was invented by David Paul Gregg in 1958 (and patented in 1970 and 1990). By 1969 Philips had developed a videodisc in reflective mode, which has great advantages over the transparent mode. MCA and Philips decided to join their efforts. They first publicly demonstrated the videodisc in 1972. Laserdisc was first available on the market, in Atlanta, on December 15, 1978, two years after the VHS VCR and four years before the CD, which is based on Laserdisc technology. Phi ...

Optical Disc
An optical disc is a flat, usuallyNon-circular optical discs exist for fashion purposes; see shaped compact disc. disc-shaped object that stores information in the form of physical variations on its surface that can be read with the aid of a beam of light. Optical discs can be reflective, where the light source and detector are on the same side of the disc, or transmissive, where light shines through the disc to be detected on the other side. Optical discs can store analog information (e.g. LaserDisc), digital information (e.g. DVD), or store on the same disc (e.g. CD Video). Their main uses are the distribution of media and data, and long-term archival. Design and technology The encoding material sits atop a thicker substrate (usually polycarbonate) that makes up the bulk of the disc and forms a dust defocusing layer. The encoding pattern follows a continuous, spiral path covering the entire disc surface and extending from the innermost track to the outermost track ...

HD-MAC
HD-MAC (High Definition Multiplexed Analogue Components) was a broadcast television systems, broadcast television standard proposed by the European Commission in 1986, as part of Eureka (organisation), Eureka 95 project. It belongs to the Multiplexed Analogue Components, MAC - Multiplexed Analogue Components standard family. It is an early attempt by the European Economic Community, EEC to provide High-definition television (HDTV) in Europe. It is a complex mix of Analog signal, analogue signal (based on the Multiplexed Analogue Components standard), multiplexed with digital sound, and assistance data for decoding (DATV). The video signal (1250 lines/50 fields per second in 16:9 aspect ratio, with 1152 visible lines) was encoded with a modified D2-MAC encoder. HD-MAC could be decoded by normal D2-MAC Standard-definition television, standard definition receivers, but no extra resolution was obtained and certain artifacts were visible. To decode the signal in full resolution a specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Compact Disc Digital Audio
Compact Disc Digital Audio (CDDA or CD-DA), also known as Digital Audio Compact Disc or simply as Audio CD, is the standard format for audio compact discs. The standard is defined in the '' Red Book'' technical specifications, which is why the format is also dubbed ''"Redbook audio"'' in some contexts. CDDA utilizes pulse-code modulation (PCM) and uses a 44,100 Hz sampling frequency and 16-bit resolution, and was originally specified to store up to 74 minutes of stereo audio per disc. The first commercially available audio CD player, the Sony CDP-101, was released in October 1982 in Japan.

Shot mostly on location at Martha's Vineyard in Massachusetts from May to October 1974, ''Jaws'' was the first major motion picture to be shot on the ocean and consequently had a troubled production, going over budget and schedule. As the art department's mechanical sharks often malfunctioned, Spielberg decided to mostly suggest the shark's presence, employing an omi ...

Test Market
A test market, in the field of business and marketing, is a geographic region or demographic group used to gauge the viability of a product or service in the mass market prior to a wide scale rollout. The criteria used to judge the acceptability of a test market region or group include: #a population that is demographically similar to the proposed target market; and #relative isolation from densely populated media markets so that advertising to the test audience can be efficient and economical. Practical use The test market ideally aims to duplicate "everything" - promotion and distribution as well as "product" - on a smaller scale. The technique replicates, typically in one area, what is planned to occur in a national launch; and the results are very carefully monitored, so that they can be extrapolated to projected national results. The area may be any one of the following: *Television area *Internet online test *Test town *Residential neighborhood *Test site A number of dec ...
