Helical Scan
Helical scan is a method of recording high-frequency signals on magnetic tape. It is used in open-reel video tape recorders, video cassette recorders, digital audio tape recorders, and some computer tape drives. History Earl E Masterson from RCA patented the first helical scan method in 1950 after stealing it from German engineer Eduard Schüller. Eduard Schüller developed an actually working helical scan method of recording in 1953 while working at AEG. With the advent of television broadcasting in Japan in the early 1950s, they saw the need for magnetic television signal recording. Dr. Kenichi Sawazaki developed a prototype helical scan recorder in 1954.

Video Camera
A video camera is an optical instrument that captures videos (as opposed to a movie camera, which records images on film). Video cameras were initially developed for the television industry but have since become widely used for a variety of other purposes. Video cameras are used primarily in two modes. The first, characteristic of much early broadcasting, is live television, where the camera feeds real time images directly to a screen for immediate observation. A few cameras still serve live television production, but most live connections are for security, military/tactical, and industrial operations where surreptitious or remote viewing is required. In the second mode the images are recorded to a storage device for archiving or further processing; for many years, videotape was the primary format used for this purpose, but was gradually supplanted by optical disc, hard disk, and then flash memory. Recorded video is used in television production, and more often surveillance and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quantel
Quantel was a company based in the United Kingdom and founded in 1973 that designed and manufactured digital production equipment for the broadcast television, video production and motion picture industries. They were headquartered in Newbury, Berkshire. Quantel acquired Snell Ltd. in March 2014. Following a period of consolidation the two companies started operating under the Snell name, trading as Snell Advanced Media or SAM, from September 2015, following the staged removal of the Quantel board of directors by incoming CEO Ray Cross. The name Quantel came from Quantised Television, in reference to the process of converting a television picture into a digital signal. History Quantel founder, Peter Michael, had previously founded Micro Consultants Group (MCG). MCG had pioneered a range of fast data conversion products that could be used for converting video signals from analog to digital and back to analog. These devices found use in many early Quantel products. In the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type C Videotape
1–inch Type C (designated Type C by SMPTE) is a professional reel-to-reel analog recording helical scan videotape format co-developed and introduced by Ampex and Sony in 1976. It became the replacement in the professional video and broadcast television industries for the then-incumbent 2–inch quadruplex videotape (2–inch Quad for short) open-reel format. Additionally, it replaced the unsuccessful type A format, also invented by Ampex, and, primarily in mainland Europe, it supplemented the type B format, invented by the Fernseh division of Bosch, but it was replaced by type C format also there. Technical detail Compared to Quad, Type C had a smaller size, comparative ease of operation, and slightly higher video quality. 1–inch Type C is capable of "trick-play" functions such as still, shuttle, and variable-speed playback, including slow motion. 2–inch quadruplex videotape machines lacked these capabilities, due to the segmented manner in which it re ...

Glass Master
In optical disc manufacturing, replication is the process of producing discs via methods that do not involve "burning" blank CD, DVD or other discs; the latter is known as duplication. The replication of optical discs involves: # the creation of a glass master from a client original master. # the creation of a nickel stamper from that glass master. # the injection molding of clear optical-grade polycarbonate substrates (clear discs) from that stamper. # the metallizing and lacquer Lacquer is a type of hard and usually shiny coating or finish applied to materials such as wood or metal. It is most often made from resin extracted from trees and waxes and has been in use since antiquity. Asian lacquerware, which may be ca ...ing of those substrates to produce compact discs and DVDs.

LaserDisc
The LaserDisc (LD) is a home video format and the first commercial optical disc storage medium, initially licensed, sold and marketed as DiscoVision, MCA DiscoVision (also known simply as "DiscoVision") in the United States in 1978. Its diameter typically spans . Unlike most optical disc standards, LaserDisc is not fully Digital data, digital, and instead requires the use of analog video signals. Although the format was capable of offering higher-quality video and audio than its consumer rivals—VHS and Betamax videotape—LaserDisc never managed to gain widespread use in North America, largely due to high costs for the players and the inability to record TV programmes. It eventually did gain some traction in that region and became somewhat popular in the 1990s. It was not a popular format in Europe and Australia. By contrast, the format was much more popular in Japan and in the more affluent regions of Southeast Asia, such as Hong Kong, Singapore and Malaysia, and was the ...

R & D
Research and development (R&D or R+D), known in Europe as research and technological development (RTD), is the set of innovative activities undertaken by corporations or governments in developing new services or products, and improving existing ones. Research and development constitutes the first stage of development of a potential new service or the production process. R&D activities differ from institution to institution, with two primary models of an R&D department either staffed by engineers and tasked with directly developing new products, or staffed with industrial scientists and tasked with applied research in scientific or technological fields, which may facilitate future product development. R&D differs from the vast majority of corporate activities in that it is not intended to yield immediate profit, and generally carries greater risk and an uncertain return on investment. However R&D is crucial for acquiring larger shares of the market through the marketisation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2 Inch Quadruplex Videotape
2-inch quadruplex videotape (also called 2″ quad video tape or quadraplex) was the first practical and commercially successful analog recording video tape format. It was developed and released for the broadcast television industry in 1956 by Ampex, an American company based in Redwood City, California. The first videotape recorder using this format was built in the same year. This format revolutionized broadcast television operations and television production, since the only recording medium available to the TV industry until then was film used for kinescopes. Since most United States West Coast network broadcast delays done by the television networks at the time were done with film kinescopes that needed time for developing, the networks wanted a more practical, cost-effective, and quicker way to time-shift television programming for later airing on the West Coast than the expense and time consumption of the processing and editing of film caused. Faced with these challenges, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
