375-line Television System
375-line corresponds to two different electronic television systems, both using 375 scan lines. One system (monochrome, 50 fields per second, interlaced) was used in Germany after 1936 along with the 180-line system, being replaced in a few years by the superior 441-line system. It was also tested in Italy around the same time. In the United States a completely different system ( field sequential color, 120 fields per second, interlaced) was used for early color television broadcasts Germany 375-line (50 fps, interlaced) television was demonstrated in 1936 on the Berlin Funkausstellung. The system used electronic cameras for live exterior broadcasts. The system was also used on experimental transmissions of the 1936 Summer Olympics (along with the 180-line system), using the Telefunken Iconoscope camera. A transmitter was setup in Berlin-Witzleben, broadcasting at 42.9 MHz. The Reichspost distributed the signal to major cities across Germany using cables. After the ...

Electronic 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.

Internationales Congress Centrum Berlin
The Internationales Congress Centrum Berlin (abbreviated ICC Berlin), located in the Westend locality of the Berlin borough of Charlottenburg-Wilmersdorf, is one of the largest conference centres in the world. It is used for conventions, theatrical productions and concerts. In April 2014 it was closed in order to remove asbestos contamination, and remains closed . In October 2021, it was temporarily reopened for the art project ''The Sun Machine Is Coming Down'' as part of the Berliner Festspiele. Overview ICC Berlin opened in 1979 (three years after the opening of the Palace of the Republic), and its architects were Ursulina Schüler-Witte and Ralf Schüler. It is 320 metres long, 80 metres wide and 40 metres high. It is linked to the neighboring Messe Berlin fairgrounds; often joining in trade shows and exhibitions.

Apollo TV Camera
The Apollo program used several television cameras in its space missions in the late 1960s and 1970s; some of these Apollo TV cameras were also used on the later Skylab and Apollo–Soyuz Test Project missions. These cameras varied in design, with image quality improving significantly with each successive model. Two companies made these various camera systems: RCA and Westinghouse Electric (1886), Westinghouse. Originally, these slow-scan television (SSTV) cameras, running at 10 frames per second (fps), produced only black-and-white pictures and first flew on the Apollo 7 mission in October 1968. A color camera – using a field-sequential color system – flew on the Apollo 10 mission in May 1969, and every mission after that. The color camera ran at the North American standard 30 fps. The cameras all used Video camera tube, image pickup tubes that were initially fragile, as one was irreparably damaged during the live broadcast of the Apollo 12 mission's first moonwalk. Startin ...

Federal Communications Commission
The Federal Communications Commission (FCC) is an independent agency of the United States federal government that regulates communications by radio, television, wire, satellite, and cable across the United States. The FCC maintains jurisdiction over the areas of broadband access, fair competition, radio frequency use, media responsibility, public safety, and homeland security. The FCC was formed by the Communications Act of 1934 to replace the radio regulation functions of the Federal Radio Commission. The FCC took over wire communication regulation from the Interstate Commerce Commission. The FCC's mandated jurisdiction covers the 50 states, the District of Columbia, and the territories of the United States. The FCC also provides varied degrees of cooperation, oversight, and leadership for similar communications bodies in other countries of North America. The FCC is funded entirely by regulatory fees. It has an estimated fiscal-2022 budget of US $388 million. It has 1,482 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
405-line Television System
The 405-line monochrome analogue television broadcasting system was the first fully electronic television system to be used in regular broadcasting. The number of television lines influences the image resolution, or quality of the picture. It was introduced with the BBC Television Service in 1936, suspended for the duration of World War II, and remained in operation in the UK until 1985. It was also used between 1961 and 1982 in Ireland, as well as from 1957 to 1973 for the Rediffusion Television cable service in Hong Kong. Sometimes called the Marconi-EMI system, it was developed in 1934 by the EMI Research Team led by Isaac Shoenberg. The figure of 405 lines had been chosen following discussions over Sunday lunch at the home of Alan Blumlein. The system used interlacing; EMI had been experimenting with a 243-line all-electronic interlaced system since 1933. In the 405 system the scanning lines were broadcast in two complementary fields, 50 times per second, creating 25 frame ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ultra High Frequency
Ultra high frequency (UHF) is the ITU designation for radio frequency, radio frequencies in the range between 300 megahertz (MHz) and 3 gigahertz (GHz), also known as the decimetre band as the wavelengths range from one meter to one tenth of a meter (one decimeter). Radio waves with frequencies above the UHF band fall into the super-high frequency (SHF) or microwave frequency range. Lower frequency signals fall into the VHF (very high frequency) or lower bands. UHF radio waves propagate mainly by Line-of-sight propagation, line of sight; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception. They are used for UHF television broadcasting, television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, satellite phones, and numerous other applications.

Exposition Internationale Des Arts Et Techniques Dans La Vie Moderne
The ''Exposition Internationale des Arts et Techniques dans la Vie Moderne'' (International Exposition of Art and Technology in Modern Life) was held from 25 May to 25 November 1937 in Paris, France. Both the Palais de Chaillot, housing the Musée de l'Homme, and the Palais de Tokyo, which houses the Musée d'Art Moderne de la Ville de Paris, were created for this exhibition that was officially sanctioned by the Bureau International des Expositions. A third building, , housing the permanent Museum of Public Works, which was originally to be among the new museums created on the hill of Chaillot on the occasion of the Exhibition, was not built until January 1937 and inaugurated in March 1939. Exhibitions At first the centerpiece of the exposition was to be a tower (" Phare du Monde") which was to have a spiraling road to a parking garage located at the top and a hotel and restaurant located above that. The idea was abandoned as it was far too expensive. Pavilions Finnish P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
