Stooky
Stooky Bill was the name given to the head of a ventriloquist dummy that Scottish television pioneer John Logie Baird used in his 1924 experiments to transmit a televised image between rooms in his laboratory at 22 Frith Street, London. Baird invented some of the first experimental television systems.

History Of Television
The concept of television was the work of many individuals in the late 19th and early 20th centuries. The first practical transmissions of moving images over a radio system used mechanical rotating perforated disks to scan a scene into a time-varying signal that could be reconstructed at a receiver back into an approximation of the original image. Development of television was interrupted by the Second World War. After the end of the war, all-electronic methods of scanning and displaying images became standard. Several different standards for addition of color to transmitted images were developed with different regions using technically incompatible signal standards. Television broadcasting expanded rapidly after World War II, becoming an important mass media, mass medium for advertising, propaganda, and entertainment. Television broadcasts can be distributed over the air by VHF and UHF radio signals from terrestrial transmitting stations, by microwave signals from Earth orbi ...

John Logie Baird
John Logie Baird FRSE (; 13 August 188814 June 1946) was a Scottish inventor, electrical engineer, and innovator who demonstrated the world's first live working television system on 26 January 1926. He went on to invent the first publicly demonstrated colour television system and the first viable purely electronic colour television picture tube. In 1928 the Baird Television Development Company achieved the first transatlantic television transmission. Baird's early technological successes and his role in the practical introduction of broadcast television for home entertainment have earned him a prominent place in television's history. In 2006, Baird was named as one of the 10 greatest Scottish scientists in history, having been listed in the National Library of Scotland's 'Scottish Science Hall of Fame'. In 2015 he was inducted into the Scottish Engineering Hall of Fame. On 26 January 2017 – IEEE unveiled a bronze street plaque at 22 Frith Street (Bar Italia), London, dedicat ...

Television
Television, sometimes shortened to TV, is a telecommunication medium for transmitting moving images and sound. The term can refer to a television set, or the medium of television transmission. Television is a mass medium for advertising, entertainment, news, and sports. Television became available in crude experimental forms in the late 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 introduced in the U.S. and most other developed countries. The availability of various types of archival st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mechanical Television
Mechanical television or mechanical scan television is a television system that relies on a mechanical scanning device, such as a rotating disk with holes in it or a rotating mirror drum, to scan the scene and generate the video signal, and a similar mechanical device at the receiver to display the picture. This contrasts with vacuum tube electronic television technology, using electron beam scanning methods, for example in cathode ray tube (CRT) televisions. Subsequently, modern solid-state liquid-crystal displays (LCD) are now used to create and display television pictures. Mechanical-scanning methods were used in the earliest experimental television systems in the 1920s and 1930s. One of the first experimental wireless television transmissions was by John Logie Baird on October 2, 1925, in London. By 1928 many radio stations were broadcasting experimental television programs using mechanical systems. However the technology never produced images of sufficient quality to become ...

Phonovision
Phonovision is a proof of concept format and experiment for recording a mechanical television signal on gramophone records. The format was developed in the late 1920s in London by Scottish television pioneer John Logie Baird. The objective was not simply to record video, but to record it synchronously, as Baird intended playback from an inexpensive playback device, which he called a "Phonovisor". Technical information The process involved mechanically linking the television scanning mechanism, a Nipkow disk, and the record-mastering turntable. The video signal from the Nipkow disc scanner was amplified and connected to the cutting stylus of the turntable. Baird had to make a number of compromises to get the process to work, among them using a picture rate of only five frames per second. Unlike Baird's other experiments (including stereoscopy, colour and infra-red night-vision), there is no evidence of a public demonstration of playback of pictures. The results were conside ...

Ventriloquist
Ventriloquism, or ventriloquy, is a performance act of stagecraft in which a person (a ventriloquist) creates the illusion that their voice is coming from elsewhere, usually a puppeteered prop known as a "dummy". The act of ventriloquism is ventriloquizing, and the ability to do so is commonly called in English the ability to "throw" one's voice. History Origins Originally, ventriloquism was a religious practice. The name comes from the Latin for 'to speak from the stomach: (belly) and (speak). The Greeks called this gastromancy ( grc-gre, εγγαστριμυθία). The noises produced by the stomach were thought to be the voices of the unliving, who took up residence in the stomach of the ventriloquist. The ventriloquist would then interpret the sounds, as they were thought to be able to speak to the dead, as well as foretell the future. One of the earliest recorded group of prophets to use this technique was the Pythia, the priestess at the temple of Apollo in Delphi, ...

Scots (language)
Scots ( endonym: ''Scots''; gd, Albais, ) is an Anglic language variety in the West Germanic language family, spoken in Scotland and parts of Ulster in the north of Ireland (where the local dialect is known as Ulster Scots). Most commonly spoken in the Scottish Lowlands, Northern Isles and northern Ulster, it is sometimes called Lowland Scots or Broad Scots to distinguish it from Scottish Gaelic, the Goidelic Celtic language that was historically restricted to most of the Scottish Highlands, the Hebrides and Galloway after the 16th century. Modern Scots is a sister language of Modern English, as the two diverged independently from the same source: Early Middle English (1150–1300). Scots is recognised as an indigenous language of Scotland, a regional or minority language of Europe, as well as a vulnerable language by UNESCO. In the 2011 Scottish Census, over 1.5 million people in Scotland reported being able to speak Scots. As there are no universally accepted c ...
