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 Op ...

Nipkow Disk
A Nipkow disk (sometimes Anglicized as Nipkov disk; patented in 1884), also known as scanning disk, is a mechanical, rotating, geometrically operating image scanning device, patented in 1885 by Paul Gottlieb Nipkow. This scanning disk was a fundamental component in mechanical television, and thus the first televisions, through the 1920s and 1930s. Operation The device is a mechanically spinning disk of any suitable material (metal, plastic, cardboard, etc.), with a series of equally-distanced circular holes of equal diameter drilled in it. The holes may also be square for greater precision. These holes are positioned to form a single-turn spiral starting from an external radial point of the disk and proceeding to the center of the disk. When the disk rotates, the holes trace circular ring patterns, with inner and outer diameter depending on each hole's position on the disk and thickness equal to each hole's diameter. The patterns may or may not partially overlap, depending on t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kroll Opera House
The Kroll Opera House (german: Krolloper, Kroll-Oper) in Berlin, Germany, was in the Tiergarten district on the western edge of the '' Königsplatz'' square (today ''Platz der Republik''), facing the Reichstag building. It was built in 1844 as an entertainment venue for the restaurant owner Joseph Kroll, and redeveloped as an opera house in 1851. It also served as the assembly hall of the Reichstag from 1933 to 1942. Severely damaged by the bombing of Berlin in World War II and the Battle of Berlin, it was demolished in 1951. History 1842–1848: Early years The Kroll story began in the Silesian capital Breslau, where the entrepreneur Joseph Kroll (1797–1848) had opened the "Kroll Winter Garden" in 1837. The Breslau authorities chose this reputable establishment to entertain the new Prussian King Frederick William IV when he visited the city in 1841. The King was impressed by the splendid, flower-decorated rooms and suggested that something similar should be initiated in ...

Funkturm Berlin
The Berliner Funkturm or Funkturm Berlin (Berlin Radio Tower) is a former broadcasting tower in Berlin. Constructed between 1924 and 1926 to designs by the architect Heinrich Straumer, it was inaugurated on 3 September 1926, on the occasion of the opening of the third Große Deutsche Funkausstellung (Great German Radio Exhibition) in the grounds of the Messe Berlin trade fair in the borough of Charlottenburg-Wilmersdorf. Nicknamed ''der lange Lulatsch'' ("the lanky lad"), the tower is one of the best-known points of interest in the city of Berlin and, while no longer used for broadcasting purposes, it remains a protected monument. Construction method The tower is built as one large steel framework construction, similar to the Eiffel Tower in Paris. The and approximately 600-metric ton radio tower was originally planned strictly as a transmitting tower, but later additions included a restaurant at a height of approximately 52 m, and observation deck at a height of approxim ...

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 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.

Manfred Von Ardenne
Manfred von Ardenne (20 January 1907 – 26 May 1997) was a German researcher and applied physicist and inventor. He took out approximately 600 patents in fields including electron microscopy, medical technology, nuclear technology, plasma physics, and radio and television technology. From 1928 to 1945, he directed his private research laboratory ''Forschungslaboratorium für Elektronenphysik''.

Kenjiro Takayanagi
was a Japanese engineer and a pioneer in the development of television. Although he failed to gain much recognition in the West, he built the world's first all-electronic television receiver, and is referred to as "the father of Japanese television". Career In 1925, Takayanagi began research on television after reading about the new technology in a French magazine. He developed a system similar to that of John Logie Baird, using a Nipkow disk to scan the subject and generate electrical signals. But unlike Baird, Takayanagi took the important step of using a cathode ray tube to display the received signal, thereby developing the first "all-electronic" television set. On December 25, 1926, Takayanagi successfully demonstrated his system at Hamamatsu Industrial High School, where he was teaching at the time (the school is now the Faculty of Engineering at Shizuoka University). The first picture he transmitted was of the Japanese katakana character made up of 40 scan lines. This ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
