Keying (telecommunications)
Keying is a family of modulation forms where the modulating signal takes one of a specific (predetermined) number of values at all times. The goal of keying is to transmit a digital signal over an analog channel. The name derives from the Morse code key used for telegraph signaling. Modulation is the general technique of shaping a signal to convey information. When a digital message has to be represented as an analog waveform, the technique and term ''keying'' (or ''digital modulation'') is used. Keying is characterized by the fact that the modulating signal will have a limited number of states (or values) at all times, to represent the corresponding digital states (commonly zero and one, although this might depend on the number of symbols used). This is in contrast to ''analogue modulation'', where an analogue signal is transmitted over an analogue channel, and where the modulated analogue signal will have an infinite number of meaningful states. Furthermore, note that keying or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keying (ship)
''Keying'' (Chinese: , p ''Qíyīng'') was a three-masted, 800-ton Foochow Chinese trading junk which sailed from China around the Cape of Good Hope to the United States and Britain between 1846 and 1848. History and voyages ''Keying'' had been purchased in August 1846 in secrecy by British businessmen in Hong Kong, defying a Chinese law prohibiting the sale of Chinese ships to foreigners. She was renamed after the Manchu official Keying. ''Keying'' was manned by 12 British and 30 Chinese sailors (the latter all Cantonese). She was commanded by Captain Charles Alfred Kellett, also British. Crew *Captains (2): Charles Alfred Kellett and So Yin Sang Hsi * Mates (2): Mr G.

Keying (electrical Connector)
Components of an electrical circuit are electrically connected if an electric current can run between them through an electrical conductor. An electrical connector is an electromechanical device used to create an electrical connection between parts of an electrical circuit, or between different electrical circuits, thereby joining them into a larger circuit. Most electrical connectors have a Gender of connectors and fasteners, genderi.e. the male component, called a ''plug'', connects to the female component, or ''socket''. The connection may be removable (as for portable equipment), require a tool for assembly and removal, or serve as a permanent electrical joint between two points. An adapter can be used to join dissimilar connectors. Thousands of configurations of connectors are manufactured for Power cord, power, data (computing), data, and audiovisual applications. Electrical connectors can be divided into four basic categories, differentiated by their function: * ''inline ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keying (official)
Keying (愛新覺羅 耆英, 21 March 1787 – 29 June 1858), also known by his romanized Mandarin Chinese name Qiying or Ch'i-ying ( Wade-Giles) and his Manchu name Kiyeng, was a Manchu statesman during the Qing dynasty of China. An imperial clansman of the house of Aisin Gioro, he began his career in the Imperial Clan Court. He conducted several peace treaties with Western powers, beginning with the Treaty of Nanking, which ended the First Opium War with Britain in 1842. Keying was sent to negotiate again in 1858 to settle the Arrow War with Britain and France, but the settlement was repudiated by the Xianfeng Emperor and he was forced to commit suicide. Early career Keying was born on 21 March 1787. A descendant of Nurhaci's ninth son Babutai (Duke Kexi of the First Rank), Keying was a member of the imperial house of Aisin Gioro, and belonged to the Manchu Plain Blue Banner in the Eight Banners. He held several prominent posts in the Qing government and was demoted sever ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vandalism
Vandalism is the action involving deliberate destruction of or damage to public or private property. The term includes property damage, such as graffiti and defacement directed towards any property without permission of the owner. The term finds its roots in an Enlightenment view that the Germanic Vandals were a uniquely destructive people. Etymology The Vandals, an ancient Germanic people, are associated with senseless destruction as a result of their sack of Rome under King Genseric in 455. During the Enlightenment, Rome was idealized, while the Goths and Vandals were blamed for its destruction. The Vandals may not have been any more destructive than other invaders of ancient times, but they did inspire English poet John Dryden to write, ''Till Goths, and Vandals, a rude Northern race, Did all the matchless Monuments deface'' (1694). However, the Vandals did intentionally damage statues, which may be why their name is associated with the vandalism of art. The term ''Va ...

Keying (graphics)
Compositing is the process or technique of combining visual elements from separate sources into single images, often to create the illusion that all those elements are parts of the same scene. Live-action shooting for compositing is variously called "chroma key", "blue screen", "green screen" and other names. Today, most, though not all, compositing is achieved through digital image manipulation. Pre- digital compositing techniques, however, go back as far as the trick films of Georges Méliès in the late 19th century, and some are still in use. Basic procedure All compositing involves the replacement of selected parts of an image with other material, usually, but not always, from another image. In the digital method of compositing, software commands designate a narrowly defined color as the part of an image to be replaced. Then the software (e.g. Natron) replaces every pixel within the designated color range with a pixel from another image, aligned to appear as part of the ...
