Metodický koncept k efektivní podpoře klíčových odborných kompetencí s využitím cizího jazyka ATCZ62 - CLIL jako výuková strategie na vysoké škole History of television in Czechoslovakia Pioneers: ● František Pilát - later post-war technical director of Barrandov Film Studio, himself built a television receiver ● Pilát was the first in Czechoslovakia to receive experimental Baird's "thirty-line" broadcast, spread in the early 1930s (1929- 1935) from Great Britain to the mid-wave of 261.5 meters. ●The most active pre-war pioneer of the television is dr. Jaroslav Šafránek, associate professor of experimental physics at Charles University in Prague ●In 1935 Šafránek built his own functioning television equipment, with which he later traveled to the Republic and presented him in public. History of television in Czechoslovakia The Ministry of Post and Telegraph refused to authorize Šafránek to broadcast television in the air. Šafranek´s equipment could only work in the laboratory and lecture halls. While Šafránek, radio amateurs and their interest organization, Czechoslovak Radio Broadcasting Corporation requested permission for experimental broadcasting of a mechanical low-line (30 line) television mainly serving radio amateurs, the Ministry of Post and Telegraph, which since 1934 closely watched developments abroad, wanted to provide frequencies for television broadcasting to some more developed Projects. He was guided by the principle - to wait, to study foreign facts and then to decide. In 1939, television research on the territory of former Czechoslovakia ended. (Threats to the Republic, Munich, and the Nazi occupation). At that time, Shafranek was working on a more advanced 240-line image decomposition device. -

A telling example of this is the US born aerobics movement as it was brought to TV in Europe, with shows such as Gym Tonic (from 1982) in France, Enorm in Form (from 1983) in Germany or the Green Goddess on BBC Breakfast Time (from 1983) in Great Britain. -

Reading Between the Lines
volume 01 issue 02/2012 READING BETWEEN THE LINES A TRANSNATIONAL HISTORY OF THE FRANCO-BRITISH ‘ENTENTE CORDIALE’ IN POST-WAR TELEVISION1 Andreas Fickers Maastricht University Grote Gracht 90-92 Postbox 616 6200 MD Maastricht The Netherlands [email protected] Andy O’Dwyer BBC Research Centre House 56 Wood Lane W12 7SB London United Kingdom [email protected] Abstract: In 1950 and 1952, the British Broadcast Corporation (BBC) and Radio Télévision Française (RTF) realized the first transnational television transmissions ever. The so called ‘Calais Experiment’ (1950) and the ‘Paris Week’ (1952) were celebrated as historic landmarks in European television and celebrated as a new ‘entente cordiale’ between the two countries. This article aims at highlighting some of the tensions that surrounded the realization of these first experiments in transnational television by embedding the historic events into the broader context of television development in Europe and by emphasizing the hidden techno- political interests at stake. In line with current trends in transnational and European television historiography, the article analyses transnational media events as performances that highlight the complex interplay of the technical, institutional and symbolic dimension of television as a transnational infrastructure. Keywords: Transnational history, BBC, RTF, Eurovision, experimental television 1 Introduction What is generally praised as the first instance of transnational television and an historic landmark in European television history, the Franco-British ‘Calais experiment’ of August 1950 and the ‘Paris week’ of July 1952, is in fact a perfect showcase to demonstrate both the ambitions and the challenges of institutionalising the new medium of television as a “champion national” both in Britain and in France. -
Thomas Edison Alexander Graham Bell
The Inventing Game Cut out the images. Cut out the name of the inventor separately. Read out the text as a clue. Can people match the correct name and image? THOMAS EDISON Clue The first great invention developed by (don’t say the name) Thomas Edison was the tin foil phonograph. A prolific producer, Edison is also known for his work with light bulbs, electricity, film and audio devices, and much more. ALEXANDER GRAHAM BELL Clue In 1876, at the age of 29, (don’t say the name) Alexander Graham Bell invented his telephone. Among one of his first innovations after the telephone was the "photophone," a device that enabled sound to be transmitted on a beam of light. GEORGE WASHINGTON CARVER Clue (Don’t say the name) George Washington Carver was an agricultural chemist who invented 300 uses for peanuts and hundreds of more uses for soybeans, pecans, and sweet potatoes. His contributions chang ed the history of agriculture in the south. ELI WHITNEY Clue (Don’t say the name) Eli Whitney invented the cotton gin in 1794. The cotton gin is a machine that separates seeds, hulls, and other unwanted materials from cotton after it has been picked. JOHANNES GUTTENBERG Clue (don’t say the name) Johannes Gutenberg was a German goldsmith and inventor best known for the Gutenberg press, an innovative printing machine that used movable type. JOHN LOGIE BAIRD Clue (don’t say the name) John Logie Baird is remembered as the inventor of mechanical television (an earlier version of television).

Any author outside of RCA intending to write a Sarnoff is a controversial figure. His supporters have Sarnoff biography who sought access to company called him a visionary and a genius, and are in awe of records would probably have received cooperation him, while critics have described him as a ruthless in proportion to how likely that author was to praise egotist. A case might be made for either label. I recognize Sarnoff’s shortcomings, yet I admire him for reasons that will become clear later in this article. -
Volume 3 Number 185 the Battle for Color Television - II
Volume 3 Number 185 The Battle for Color Television - II Lead: In the 1940s two corporate giants, NBC and CBS, fought over the means of broadcasting television in color. Tag: A Moment in Time with Dan Roberts. Content: After World War II, NBC under its chairman, David Sarnoff, had begun commercial black and white television broadcasts and was selling TVs by the truckload. Its great rival, William Paley’s CBS, was producing Black and White shows such as Ed Sullivan but at the same was experimenting with color television in hopes of getting a jump on the competition. The problem was the CBS color system used a spinning wheel with color filters in the camera and in the TV set and produced a signal which could not be received by existing black and white TVs without a relatively expensive converter. Sarnoff had too many sets out there to give up his advantage and began a campaign to smear the CBS system. NBC was working on an all-electronic color system, without the cumbersome spinning wheels, but which they thought would not be ready for years. By 1950 CBS was ready and had applied to the Federal Communications Commission to designate its system as the only standard. Both sides were at it now. Secret meetings with congressmen, lobbying, accusations in the media. Millions were at stake. Finally, the FCC approved CBS color in October 1950 and the courts struck down NBC’s court challenge. The problem was, not a single CBS color set had been sold, just a lot of useless black and white sets. -
