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 ...

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 ...

Federal Communications Commission
The Federal Communications Commission (FCC) is an independent agency of the United States government that regulates communications by radio, television, wire, internet, wi-fi, 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 established pursuant to the Communications Act of 1934 to replace the radio regulation functions of the previous 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 in North America. The FCC is funded entirely by regulatory fees. It has an estimated fiscal-2022 budg ... [...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. 405-line was approved as System A in the CCIR assignment of broadcast systems. 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 l ...

525 Lines
525-line (or EIA 525/60) is an American standard-definition television resolution used since July 1, 1941, mainly in the context of analog TV broadcast systems. It consists of a 525-line raster, with 486 lines carrying the visible image at 30 (29.97 with color) interlaced frames per second. It was eventually adopted by countries using 60 Hz utility frequency as TV broadcasts resumed after World War II.

Ultra High Frequency
Ultra high frequency (UHF) is the ITU designation for 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 decimetre). 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; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception. They are used for 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. The IEEE defines the UHF radar band as frequencies between 300 MHz and 1 GHz. Two other IEEE ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.

Loewe (electronics)
Loewe Technology GmbH, doing business as Loewe (), is a German company that develops, designs, manufactures, and sells consumer electronics and electromechanical products and systems. The company was founded in Berlin, in 1923, by brothers Siegmund and David L. Loewe.

Siegmund Loewe belonged to a circle which promoted public broadcasting in Germany and did his best to initiate what later became known as the radio boom. His work with the young physicist Manfred von Ardenne in 1926 led to the development of the Loewe 3NF, an early attempt to combine several functions into one electronic device, similar to the modern integrated circuit. It was the basis for the broadcast receiver OE 3 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
