Information and Communication Technologies: 11. Television World in History
Information and communication technologies: 11. Television world in history. Analog and digital. 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. -

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. -

Transformative Choices: A Review of 70 Years of FCC Decisions Sherille Ismail FCC Staff Working Paper 1 Federal Communications Commission Washington, DC 20554 October, 2010 FCC Staff Working Papers are intended to stimulate discussion and critical comment within the FCC, as well as outside the agency, on issues that may affect communications policy. The analyses and conclusions set forth are those of the authors and do not necessarily reflect the view of the FCC, other Commission staff members, or any Commissioner. Given the preliminary character of some titles, it is advisable to check with the authors before quoting or referencing these working papers in other publications. Recent titles are listed at the end of this paper and all titles are available on the FCC website at http://www.fcc.gov/papers/. Abstract This paper presents a historical review of a series of pivotal FCC decisions that helped shape today’s communications landscape. These decisions generally involve the appearance of a new technology, communications device, or service. In many cases, they involve spectrum allocation or usage. Policymakers no doubt will draw their own conclusions, and may even disagree, about the lessons to be learned from studying the past decisions. From an academic perspective, however, a review of these decisions offers an opportunity to examine a commonly-asserted view that U.S. regulatory policies — particularly in aviation, trucking, and telecommunications — underwent a major change in the 1970s, from protecting incumbents to promoting competition. The paper therefore examines whether that general view is reflected in FCC policies. It finds that there have been several successful efforts by the FCC, before and after the 1970s, to promote new entrants, especially in the markets for commercial radio, cable television, telephone equipment, and direct broadcast satellites. -

The Origination and Evolution of Radio Traffic Analysis: the World War I Era
UNCLASSI Fl ED The Origination and Evolution of Radio Traffic Analysis: The World War I Era (b )(3)-P. L. 86-36 Not unlike the telegraph and ita influence on the American Civil War, the invention of radio had a profound affect on World War I military operations and in all conflicts since 1901. Signals intelligence, a new form. of intelligence produced from. the intercept of radio traffic, developed on a parallel course with radio during the early years of the twentieth century. Although signals intelligence was identified as a method to produce useful and critical information during war, it did not mature as a significant tool until after the ,.War to End All Wars." Radio traffic analysis, a branch of signals intelligence, was not even recognized as a separate technique until long after the First World War ended. Nevertheless, traffic analysis, or TIA, existed as a function in that era and made significant contributions to military operations and to the development ofsignals intelligence. For the American signals intelligence service, radio traffic analysis originated as a technique in the codebreaking section and with the clerks in the goniometric or Direction Finding (DF) service of the American Expeditionary Force. The early cryptanalysts developed TIA techniques to identify the originator and receiver of radio messages and to determine the more important encoded or enciphered messages to attack. TIA also evolved in the DF service with the clerks who discovered ways to produce intelligence from analysis of the externals of messages and from the location ofthe radio transmitters. The increasingly more complex communications systems which defied cryptanalytic attack provided the impetus for these developments.
