Einheitsempfänger
In August 1939, Nazi Germany introduced the Einheits-Fernseh-Empfänger E1 (i.e. ''Unitary-TV-receiver E1''), also called Volksfernseher (i.e. ''People's TV''), a 441-line, 25 interlaced frames per second (or more correctly 50 fields per second) television system. The TV was presented to the public in the 16th International radio exhibition Berlin. History The project started in 1938, associating the Reichspost and several companies, including Bosch, Blaupunkt, Loewe, Lorenz, TeKaDe and Telefunken. The objective was to produce 10,000 units, but the start of World War II caused only about 50 devices to be installed in military hospitals and various government departments. The Berlin transmitter was destroyed by Allied bombing in November 1943. Like British televisions of the era, the Einheitsempfänger could receive only one channel with its frequency pre-tuned at the factory to reduce construction costs. Surviving sets Only a few surviving and functioning units are known: * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
441-line Television System
441-line is the number of scan lines in some early electronic monochrome analog television systems. Systems with this number of lines were used with 25 interlaced frames per second in France from 1937 to 1956, Germany from 1939 to 1943, Italy from 1939 to 1940, Japan in 1939, as well as by RCA in the United States with 30 interlaced frames per second from 1938 to 1941. Broadcasts were planned in Finland for 1940, but eventually cancelled due to World War II. Some experiments with a similar system were carried out on the USSR in the 1930s. Germany After trials with a 375-line system during the Berlin Olympic Games of 1936, by 1937 Germany had introduced a 441-line with 50 interlaced fields per second television system that replaced the previous 180 lines network relayed by a special Reichspost (National Post Office) cable network in the country's main cities (Berlin, Hamburg, Munich, Bayreuth, Nuremberg). The system's line frequency was 11.025 kHz and the broadcast freq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Internationale Funkausstellung Berlin
The IFA ( ), or Internationale Funkausstellung Berlin (International radio exhibition Berlin, a.k.a. 'Berlin Radio Show'), is one of the oldest industrial exhibitions in Germany. Between 1924 and 1939 it was an annual event, but from 1950 it was held every other year until 2005. Since then it has become an annual event again, held in September. Today it is one of the world's leading trade shows for consumer electronics and home appliances. It offers the opportunity to exhibitors to present their latest products and developments to the general public. As a result of daily reporting in almost all the German media, the radio exhibition and the showcased technology receives a large amount of attention around the globe. In the course of its history, many world innovations were first seen at the exhibition. IFA is "Europe's biggest tech show". 245,000 visitors and 1,645 exhibitors attended IFA 2015.

History Of Television In Germany
The first regular electronic television service in Germany began in Berlin on March 22, 1935, as Deutscher Fernseh Rundfunk. Broadcasting from the Fernsehsender Paul Nipkow, it used a 180-line system, and was on air for 90 minutes, three times a week. Very few receivers were ever privately owned, and viewers went instead to (television parlors). During the 1936 Summer Olympics, broadcasts, up to eight hours a day, took place in Berlin and Hamburg. The Nazis intended to use television as a medium for their propaganda once the number of television sets was increased, but television was able initially to reach only a small number of viewers, in contrast to radio. Despite many technical improvements to camera technology, allowing for higher resolution imaging, by 1939, and the start of World War II, plans for an expansion of television programming were soon changed in favor of radio. The production of the TV receiver E1, that had just started was cancelled because of the war. Neve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Telecommunications In Germany
History is the systematic study of the past, focusing primarily on the Human history, human past. As an academic discipline, it analyses and interprets evidence to construct narratives about what happened and explain why it happened. Some theorists categorize history as a social science, while others see it as part of the humanities or consider it a hybrid discipline. Similar debates surround the purpose of history—for example, whether its main aim is theoretical, to uncover the truth, or practical, to learn lessons from the past. In a more general sense, the term ''history'' refers not to an academic field but to the past itself, times in the past, or to individual texts about the past. Historical research relies on Primary source, primary and secondary sources to reconstruct past events and validate interpretations. Source criticism is used to evaluate these sources, assessing their authenticity, content, and reliability. Historians strive to integrate the perspectives o ...

Television Sets
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 ...

Hochschule Mittweida
The Hochschule Mittweida () is a public university of applied science located in Mittweida, Germany, founded in 1867. History The University of Applied Sciences Mittweida is the second-largest public university of applied sciences in Saxony. It has had almost 80,000 alumni from almost 40 countries worldwide. Founded in 1867 as Technicum, the university first served the education of machine-building engineers, and it was one of the largest private schools in Germany at the turn of the century. After the takeover by the National Socialists, the Technicum lost its status as a private school, and in 1935 became the Engineering School Mittweida (Ingenieurschule Mittweida). In the 1960s, due to the success of the electrotechnical training program, the school became the Engineering College Mittweida. In 1980, it received the right to award the academic degree of doctor engineer. In 1992, after reunification, the college received a new start as a university of applied sciences. Notab ...

Frequency
Frequency is the number of occurrences of a repeating event per unit of time. Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light. The interval of time between events is called the period. It is the reciprocal of the frequency. For example, if a heart beats at a frequency of 120 times per minute (2 hertz), its period is one half of a second. Special definitions of frequency are used in certain contexts, such as the angular frequency in rotational or cyclical properties, when the rate of angular progress is measured. Spatial frequency is defined for properties that vary or cccur repeatedly in geometry or space. The unit of measurement of frequency in the International System of Units (SI) is the hertz, having the symbol Hz. Definitions and units For cyclical phenomena such as oscillations, waves, or for examp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
