Intermediate Film System
The intermediate film system was a television process in which film stock, motion picture film was processed almost immediately after it was exposed in a camera, then scanned by a television scanner, and transmitted over the air. This system was used principally in Great Britain, Britain and Germany where television cameras were not sensitive enough to use reflected light, but could transmit a suitable image when a bright light was shone through motion picture film directly into the camera lens. History John Logie Baird began developing the process in 1932, borrowing the idea of Georg Oskar Schubert from his licensees in Germany, where it was demonstrated by Fernseh AG in 1932 and used for broadcasting in 1934. The BBC One, BBC used Baird's version of the process during the first three months of its then-"high-definition" television service from November 1936 through January 1937, and Fernsehsender Paul Nipkow, German television used it during broadcasts of the 1936 Summer Olympics ...

1936 Summer Olympics
The 1936 Summer Olympics (), officially the Games of the XI Olympiad () and officially branded as Berlin 1936, were an international multi-sport event held from 1 to 16 August 1936 in Berlin, then capital of Nazi Germany. Berlin won the bid to host the Games over Barcelona on the 29th IOC Session on 26 April 1931. The 1936 Games marked the second and most recent time the International Olympic Committee gathered to vote in a city bidding to host those Games. Later rule modifications forbade cities hosting the bid vote from being awarded the games. To outdo the 1932 Summer Olympics, 1932 Los Angeles Games, Adolf Hitler had Olympiastadion (Berlin), a new 100,000-seat track and field stadium built, as well as six gymnasiums and other smaller arenas. The Games were the first to be Fernsehsender Paul Nipkow, televised, with radio broadcasts reaching 41 countries.Rader, Benjamin G.

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. The format uses magnetic tape and 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 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 motion picture film. Since most United States network broadcast delays by the television networks at the time used kinescope film that took time to develop, the networks wanted a more practical, cost-effective, and quicker way to time shifting, time-shift television programming for later airing in Western time zones than the expensive and time-consuming processing and editing of film. Faced with these challenges, broadc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vladimir Zworykin
Vladimir Kosma Zworykin (1888/1889July 29, 1982) was a Russian-American inventor, engineer, and pioneer of television technology. Zworykin invented a television transmitting and receiving system employing cathode-ray tubes. He played a role in the practical development of television from the early thirties, including charge storage-type tubes, infrared image tubes and the electron microscope. Early life and education Vladimir Zworykin was born in Murom, Russia, in 1888 or 1889, to the family of a prosperous merchant, merchants. He had a relatively calm upbringing, and he rarely saw his father except on religious holidays. He studied at the St. Petersburg Institute of Technology, under Boris Rosing. He helped Rosing with experimental work on television in the basement of Rosing's private lab at the School of Artillery of Saint Petersburg. They worked on the problem of "electrical telescopy," something Zworykin had never heard of before. At this time, electrical telescopy (or te ...

Philo Taylor Farnsworth
Philo Taylor Farnsworth (August 19, 1906 – March 11, 1971), "The father of television", was the American inventor and pioneer who was granted the first patent for the television by the United States Government. Burns, R. W. (1998), ''Television: An international history of the formative years''. IET History of Technology Series, 22. LondonThe Institution of Engineering and Technology (IET) p. 370. . He also invented a video camera tube, and the image dissector. He commercially produced and sold a fully functioning television system, complete with receiver and camera—which he produced commercially through the Farnsworth Television and Radio Corporation from 1938 to 1951, in Fort Wayne, Indiana. In later life, Farnsworth invented a small nuclear fusion device, the Farnsworth Fusor, employing inertial electrostatic confinement (IEC). Like many fusion devices, it was not a practical device for generating nuclear power, although it provides a viable source of neutrons. The de ...

Video Camera Tube
Video camera tubes are devices based on the cathode-ray tube that were used in television cameras to capture television images, prior to the introduction of charge-coupled device (CCD) image sensors in the 1980s. Several different types of tubes were in use from the early 1930s, and as late as the 1990s. In these tubes, an cathode ray, electron beam is scanned across an image of the scene to be broadcast focused on a target. This generated a current that is dependent on the brightness of the image on the target at the scan point. The size of the striking ray is tiny compared to the size of the target, allowing 480–486 horizontal scan lines per image in the NTSC format, 576 lines in PAL, and as many as 1035 lines in Multiple sub-Nyquist sampling encoding, Hi-Vision. Cathode-ray tube Any vacuum tube which operates using a focused beam of electrons, originally called cathode rays, is known as a cathode-ray tube (CRT). These are usually seen as display devices as used in older (i. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kinescope
Kinescope , shortened to kine , also known as telerecording in Britain, is a recording of a television program on motion picture film directly through a lens focused on the screen of a video monitor. The process was pioneered during the 1940s for the preservation, re-broadcasting, and sale of television programs before the introduction of quadruplex videotape, which from 1956 eventually superseded the use of kinescopes for all of these purposes. Kinescopes were the only practical way to preserve live television broadcasts prior to videotape. Typically, the term can refer to the process itself, the equipment used for the procedure (a movie camera mounted in front of a video monitor, and synchronized to the monitor's scanning rate), or a film made using the process. Film recorders are similar, but record source material from a computer system instead of a television broadcast. A telecine is the inverse device, used to show film directly on television. The term originally refer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sound-on-film
Sound-on-film is a class of sound film processes where the sound accompanying a picture is recorded on photographic film, usually, but not always, the same strip of film carrying the picture. Sound-on-film processes can either record an Analog signal, analog sound track or Digital data, digital sound track, and may record the signal either optical sound, optically or magnetism, magnetically. Earlier technologies were sound-on-disc, meaning the film's soundtrack would be on a separate phonograph record. History Sound on film can be dated back to the early 1880s, when Charles E. Fritts filed a patent claiming the idea. In 1923 a patent was filed by E. E. Ries, for a variable density soundtrack recording, which was submitted to the SMPE (now Society of Motion Picture and Television Engineers, SMPTE), which used the mercury vapor lamp as a modulating device to create a variable-density soundtrack. Later, Theodore Case, Case Laboratories and Lee De Forest#Phonofilm sound-on-film pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
35mm Movie Film
35 mm film is a film gauge used in filmmaking, and the film standard. In motion pictures that record on film, 35 mm is the most commonly used gauge. The name of the gauge is not a direct measurement, and refers to the nominal width of the 35 mm format photographic film, which consists of strips wide. The standard negative pulldown, image exposure length on 35 mm for movies ("single-frame" format) is four film perforations, perforations per Film frame, frame along both edges, which results in 16 frames per foot of film. A variety of largely proprietary gauges were devised for the numerous camera and projection systems being developed independently in the late 19th and early 20th centuries, along with various film feeding systems. This resulted in cameras, projectors, and other equipment having to be calibrated to each gauge. The 35 mm width, originally specified as inches, was introduced around 1890 by William Kennedy Dickson and Thomas Edison, using 120 film st ...

Fernsehsender Paul Nipkow
The Fernsehsender "Paul Nipkow" (''TV Station Paul Nipkow'') , also known as Deutscher Fernseh-Rundfunk (''German Television Broadcasting''), in Berlin, Germany, was the first regular television service in the world. It was on the air from 22 March 1935, until it was shut down in 1944. The station was named after Paul Gottlieb Nipkow, the inventor of the Nipkow disk. History Parallel to the experiments by John Logie Baird in the United Kingdom, by Herbert E. Ives and Charles Francis Jenkins in the United States, as well as by Kenjiro Takayanagi in Japan, television pioneers like Dénes Mihály and Manfred von Ardenne had organised experimental television transmissions in Berlin since 1928. In the same year, Telefunken presented a television set prototype during the Internationale Funkausstellung industrial exhibition. From 1929 television test programs were regularly aired from the Funkturm Berlin transmitter (''Rundfunksender Witzleben''). The first public transmission was i ...

Television
Television (TV) is a telecommunication medium for transmitting moving images and sound. Additionally, the term can refer to a physical television set rather than the medium of transmission. Television is a mass medium for advertising, entertainment, news, and sports. The medium is capable of more than "radio broadcasting", which refers to an audio signal sent to radio receivers. Television became available in crude experimental forms in the 1920s, but only after several years of further development was the new technology marketed to consumers. After World War II, an improved form of black-and-white television broadcasting became popular in the United Kingdom and the United States, and television sets became commonplace in homes, businesses, and institutions. During the 1950s, television was the primary medium for influencing public opinion.Diggs-Brown, Barbara (2011''Strategic Public Relations: Audience Focused Practice''p. 48 In the mid-1960s, color broadcasting was ...

BBC One
BBC One is a British free-to-air public broadcast television channel owned and operated by the BBC. It is the corporation's oldest and flagship channel, and is known for broadcasting mainstream programming, which includes BBC News television bulletins, primetime drama and entertainment, and live BBC Sport events. The channel was launched on 2 November 1936 under the name BBC Television Service, which was the world's first regular television service with a high level of image resolution. It was renamed BBC TV in 1960 and used this name until the launch of the second BBC channel, BBC2, in 1964. The main channel then became known as BBC1. The channel adopted the current spelling of BBC One in 1997. The channel's annual budget for 2012–2013 was £1.14 billion. It is funded by the television licence fee together with the BBC's other domestic television stations and shows uninterrupted programming without commercial advertising. The television channel had the highest reach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
