Intermediate Film System
The intermediate film system was a television process in which 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 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 shown through motion picture film directly into the camera lens. 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 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 German television used it during broadcasts of the 1936 Summer Olympics.

1936 Summer Olympics
The 1936 Summer Olympics (German: ''Olympische Sommerspiele 1936''), officially known as the Games of the XI Olympiad (German: ''Spiele der XI. Olympiade'') and commonly known as Berlin 1936 or the Nazi Olympics, were an international multi-sport event held from 1 to 16 August 1936 in Berlin, Germany. Berlin won the bid to host the Games over Barcelona at 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 that was bidding to host those Games. Later rule modifications forbade cities hosting the bid vote from being awarded the games. To outdo the 1932 Los Angeles Games, Reich Führer Adolf Hitler had 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 televised, with radio broadcasts reaching 41 countries.Rader, Benjamin G. "American Sports: From the Age of Folk Games to the Age of Televised Spo ...

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 shifting, 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.

Vladimir Zworykin
Vladimir Kosma Zworykin; or with the patronymic as ''Kosmich''; or russian: Кузьмич, translit=Kuz'mich, label=none. Zworykin anglicized his name to ''Vladimir Kosma Zworykin'', replacing the patronymic with the name ''Kosma'' as a middle name, and using the nonstandard transliteration ''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 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 Ro ...

Philo Taylor Farnsworth
Philo Taylor Farnsworth (August 19, 1906 – March 11, 1971) was an American inventor and television pioneer. He made many crucial contributions to the early development of all-electronic television. He is best known for his 1927 invention of the first fully functional all-electronic image pickup device (video camera tube), the image dissector, as well as the first fully functional and complete all-electronic television system.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. . Farnsworth developed a 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–Hirsch fusor, employing inertial electrostatic confinement (IEC). Like many fusi ...

Video Camera Tube
Video camera tubes were 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 electron beam was scanned across an image of the scene to be broadcast focused on a target. This generated a current that was dependent on the brightness of the image on the target at the scan point. The size of the striking ray was tiny compared to the size of the target, allowing 483 horizontal scan lines per image in the NTSC format, 576 lines in PAL, and as many as 1035 lines in 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.e., non-flat panel) television receivers and computer d ... [...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 programmes 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 Kinescope 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. The term originally referred to the cathode ray tube used in television receivers, as named by inventor Vladimir K. Zworykin in 1929. Hence, the recordings were known in full as kinescope films or kines ... [...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 sound track or digital sound track, and may record the signal either optically or 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 SMPTE), which used the mercury vapor lamp as a modulating device to create a variable-density soundtrack. Later, Case Laboratories and Lee De Forest attempted to commercialize this process, when they developed an Aeolite glow lamp, which was deployed at Movietone Newsreel at the Roxy Theatre ...

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 image exposure length on 35 mm for movies ("single-frame" format) is four perforations per 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 century and early 20th century, as well as a variety of 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 stock supplied by George Eastman. ...

Fernsehsender Paul Nipkow
The Fernsehsender "Paul Nipkow" (''TV Station Paul Nipkow'') in Berlin, Germany, was the first public television station in the world. Carrying programming from Deutscher Fernseh-Rundfunk, 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 introduced in the Kroll Opera Ho ...

Television
Television, sometimes shortened to TV, is a telecommunication medium for transmitting moving images and sound. The term can refer to a television set, or the medium of television transmission. Television is a mass medium for advertising, entertainment, news, and sports. Television became available in crude experimental forms in the late 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 introduced in the U.S. and most other developed countries.
