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). Baird also patented inventions related to radar and fibre optics. -

The History of Television
The History of Television Television was not invented by a single inventor, instead many people working together and alone over the years, contributed to the evolution of television. At the dawn of television history there were two distinct paths of technology experimented with by researchers. Early inventors attempted to either build a mechanical television system based on the technology of Paul Nipkow's rotating disks; or they attempted to build an electronic television system using a cathode ray tube developed independently in 1907 by English inventor A.A. Campbell-Swinton and Russian scientist Boris Rosing. Electronic television systems worked better and eventual replaced mechanical systems. German, Paul Nipkow developed a rotating-disc technology to transmit pictures over wire in 1884 called the Nipkow disk. Paul Nipkow was the first person to discover television's scanning principle, in which the light intensities of small portions of an image are successively analyzed and transmitted. In the 1920's, John Logie Baird patented the idea of using arrays of transparent rods to transmit images for television. Baird's 30 line images were the first demonstrations of television by reflected light rather than back-lit silhouettes. John Logie Baird based his technology on Paul Nipkow's scanning disc idea and later developments in electronics. Charles Jenkins invented a mechanical television system called radiovision and claimed to have transmitted the earliest moving silhouette images on June 14, 1923. Electronic television is based on the development of the cathode ray tube, which is the picture tube found in modern TV sets. German scientist, Karl Braun invented the cathode ray tube oscilloscope (CRT) in 1897. -

Investigations into the Emergence of British Television 1926-1936 1 Investigations into the Emergence of British Television 1926-1936 November 2017 A Critical Review submitted to Aberystwyth University in partial fulfilment of the degree of Doctor of Philosophy (PhD by Published Work) in the Department of Theatre, Film and Television Studies Donald F McLean Aberystwyth University Investigations into the Emergence of British Television 1926-1936 2 Abstract This Critical Review discusses the significance of the author’s published works and their impact on the history of the emergence of British television between 1926 and 1936. Although events in television within this period have since been well- documented, the related debates have tended to be specialist in scope and restricted to technology-centric or institution-centric viewpoints. Within this period of complex, rapid technological change, the author’s published works introduce the principle of embracing multiple disciplines for comparative analysis. The author’s application of that principle opens up long- established views for further debate and provides a re-assessment of early British television within a broader context. The rewards of this approach are a view of events that not only avoids nationalistic bias and restrictions of a single institutional viewpoint, but also tackles the complex interdependencies of technology, of service provision and of content creation. These published works draw attention to the revolutionary improvements that enabled the BBC’s 1936 service and the re-definition of television, yet also emphasise the significance of the previous television broadcast services. The most important innovation within these works has been the author’s discovery and in-depth study of artefacts from that earlier period. -

Satellite Delivery of 3D Television 16 September 2009
Satellite delivery of 3D television 16 September 2009 Two types of reception sites are being created: one mimics a home environment using longer content, while the other is a public venue with shorter content. A ‘home site’ has been set up at ESTEC, ESA’s research and technology centre in Noordwijk, the Netherlands. The 3D channel is being transmitted from Eurobird 9A, located at 9°E, on 11 747 MHz with horizontal polarisation and a symbol rate of 27 500. Videos are transmitted in a modified side-by-side arrangement. To view them, a 3D-capable television and appropriate glasses are required. ESA is taking a practical step forward in the ultimate Since the first broadcasts in the 1920s by Scottish television viewer experience: satellite-delivered 3D engineer John Logie Baird - the first person to television at home. Through the Advanced Research in Telecommunications Systems (ARTES) programme and produce a live, moving, television image from the project ‘Stereoscopic Broadcasting’, ESA is reflected light - broadcasting and viewing have providing its support to the companies OpenSky and been continually improved. In 2008 there were SkyLogic in the provision of a complete service offering more than 100 million European homes receiving for consumer-oriented 3D television broadcasting. TV programmes transmitted by satellites, either by Credits: ESA direct reception or through cable distribution systems. Viewers have enjoyed the arrival of High Definition (PhysOrg.com) -- As part of its Advanced (HD), surround-sound and both widescreen and Research in Telecommunications Systems flatscreen televisions, all aimed at enhancing the programme, ESA is taking a practical step towards user experience. -
DVB - the History of Television
DVB - The History of Television A History of Television by Jean-Jacques Peters (EBU) Contents Preface The foundations The first broadcasts Highlights Colour television On the primaries Colour television Digital television Technological developments transmission Television film Video recording Television cameras scanning Towards other screens Electronic special effects Digital images Preface Did you know there are more television sets in the world than there are telephones? Even the television professionals find it hard to believe. However the statistics prove it to be true; according to official figures from the International Telecommunication Union there were 565 million telephones in 1983, and 600 million television sets. Other figures are just as impressive: in Belgium, from 1967 to 1982, the average time spent watching television by children from 10 to 13 years, increased from 82 to 146 minutes per day. Stupefying in every sense of the word. Our senses are assailed every day by the attraction of the visual message. Its all-pervasiveness and instantaneity are finely tuned to our way of thinking, whether we be hard-pressed or lazy. We expect from it effortless pleasure and hot news. A Chinese proverb tells us a picture is worth ten thousand words. But the stupefaction takes its toll and we thirst for more. Images pour over us in a never-ending torrent. Television has already modified our social behaviour. It fosters, for example, our taste for things visual the impact of the picture and its colours. It encourages in us a yearning for the big spectacle the razzmatazz and the forthright declaration. The effect can be seen in the way we react one to another and in the world of advertising. -
Hardware and Software for Mechanical Television System
Hardware and Software for Mechanical Television System This document provides all the required information for being able to build / tweak a mechanical narrow band television similar to the prototype show in this Youtube video: http://www.youtube.com/watch?v=tslWfnsTwPg . Building-up and tweaking this kind of mechanical and electronic hardware requires some experience and a lot of patience. Electromechanical parts (speed response vs torque of the available motor , disc inertia and size) have an impact on the global system behavior, so that the prototype will not be “plug-and-play”. A lot of adjustment means have been implemented in the schematics to face this kind of issues. However, it remains possible that you will have to modify some values/components to match with your mechanical configuration, especially in the motor synchronization system (as in all other kinds of mechanical TV designs). If experienced in homebrew design but not familiar at all with NBTV and/or mechanical television, first have a look to this well documented website: http://www.earlytelevision.org/dupouy.html The design proposed in this document is modular so that it is possible to chose some parts from it, if not all of them, according to one's preferences: * Video synchronization extractor + Y / green extractor * Motor driving system disc synchronization with video * Vsync triggered stroboscope for an easy adjustment of vertical synchronization by the user. * Low loss LED anode voltage regulator (avoids thermal dissipation issues and reduces power consumption), made with very common components. * SECAM-like color decoder + audio separator, if willing to build a color TV (includes a PIC1F819). -
