Telesoftware
The term telesoftware was coined by W.J.G. Overington who invented the concept in 1974; it literally means “software at a distance” and it often refers to the transmission of programs for a microprocessor or home computer via broadcast teletext, though the use of teletext was just a convenient way to implement the invention, which had been invented as a theoretical broadcasting concept previously. The concept being of producing local interactivity without the need for a return information link to a central computer. The invention arose as spin-off from research on function generators for a hybrid computer system for use in simulation of heat transfer in food preservation, and thus from outside of the broadcasting research establishments. Software bytes are presented to a terminal as pairs of standard teletext characters, thus utilizing an existing and well-proven broadcasting system. History Telesoftware was pioneered in the UK during the 1970s and 1980s, and a paper on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teletext
A British Ceefax football index page from October 2009, showing the three-digit page numbers for a variety of football news stories Teletext, or broadcast teletext, is a standard for displaying text and rudimentary graphics on suitably equipped television sets. Teletext sends data in the broadcast signal, hidden in the invisible vertical blanking interval area at the top and bottom of the screen. The teletext decoder in the television buffers this information as a series of "pages", each given a number. The user can display chosen pages using their remote control. In broad terms, it can be considered as Videotex, a system for the delivery of information to a user in a computer-like format, typically displayed on a television or a dumb terminal, but that designation is usually reserved for systems that provide bi-directional communication, such as Prestel or Minitel. Teletext was created in the United Kingdom in the early 1970s by John Adams, Philips' lead designer for video di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multimedia Home Platform
Multimedia Home Platform (DVB-MHP) is an open middleware system standard designed by the DVB project for interactive digital television. The MHP enables the reception and execution of interactive, Java-based applications on a TV-set. Interactive TV applications can be delivered over the broadcast channel, together with audio and video streams. These applications can be for example information services, games, interactive voting, e-mail, SMS or shopping. MHP applications can use an additional return channel that has to support IP. Deployment In May 2010 the largest deployments DVB-MHP are in Italy (DVB-T), Korea ( DVB-S), Belgium ( DVB-C) and Poland ( DVB-S) with trials or small deployments in Germany, Spain, Austria, Colombia, Uruguay and Australia. MHP service was also offered in Finland by Finnish Broadcasting Corporation (Yleisradio), but the service was shut down at the end of 2007 after technical failure. The shutdown wasn't ever officially announced. Ultimately the reaso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ceefax
Ceefax (, punning on "seeing facts") was the world's first teletext information service and a forerunner to the current BBC Red Button service. Ceefax was started by the BBC in 1974 and ended, after 38 years of broadcasting, at 23:32:19 BST (11:32 PM BST) on 23 October 2012, in line with the digital switchover being completed in Northern Ireland.Pete Clifton Points of View 9 November 2008Test Cards and Ceefax BBC Archive To receive a desired page of text on a teletext-capable receiver, the user would enter a three-digit page number on the device. Once the page number was entered, the selected page would display on the user's screen upon its actual transmission, which would have required a wait of several seconds. There were many pages to choose from and they could be displayed either on a bl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BBC Micro
The British Broadcasting Corporation Microcomputer System, or BBC Micro, is a series of microcomputers and associated peripherals designed and built by Acorn Computers in the 1980s for the BBC Computer Literacy Project. Designed with an emphasis on education, it was notable for its ruggedness, expandability, and the quality of its operating system. An accompanying 1982 television series, ''The Computer Programme'', featuring Chris Serle learning to use the machine, was broadcast on BBC2. After the Literacy Project's call for bids for a computer to accompany the TV programmes and literature, Acorn won the contract with the ''Proton'', a successor of its Atom computer prototyped at short notice. Renamed the BBC Micro, the system was adopted by most schools in the United Kingdom, changing Acorn's fortunes. It was also successful as a home computer in the UK, despite its high cost. Acorn later employed the machine to simulate and develop the ARM architecture. While nine models ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BBC Micro Expansion Unit
A BBC Micro expansion unit, for the BBC Micro is one of a number of peripherals in a box with the same profile and styling as the main computer. Second Processors The second processors are connected to Acorn's proprietary and trademarked ''Tube'' interface. Only one second processor unit could be connected at a time to a BBC Micro, although a Master 128 could also have a co-processor fitted internally at the same time. The terminology of ''second'' processor was slightly misleading, since connected and switched on, the system worked on a "host-parasite" model, with the processor in the external unit taking control while the 6502 in the "main" computer simply took on responsibility for I/O. 6502 Second Processor The 6502 Second Processor (using a 65C02) was clocked at 3 MHz, a full 50% faster than the 6502 inside a BBC Model B, and also had 64 KB of RAM, of which typically 30–44 KB was free for application data (compared to as little as 8.5 KB on an unexpa ...

The Micro User
''The Micro User'' (titled ''BBC Micro User'' in the first three issues) was a British specialist magazine catering to users of the BBC Microcomputer series, Acorn Electron, Acorn Archimedes and, to a limited extent, the Cambridge Z88. It had a comprehensive mix of reviews of games, application software, and the latest Acorn computers; type-in programs (duplicated on a "cover disk" which was available separately), a correspondence page offering help with computer problems, and approachable technical articles on programming and the BBC Micro's internals. The magazine hosted the long-running ''Body Building'' series by Mike Cook, in which each article introduced a small electronics project that could be built and connected to one of the BBC Micro's I/O ports. The project could be ordered in kit form or fully assembled, or the reader could source the parts and design as the articles contained a circuit diagram. There were regular columns on adventure gaming from two successive c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meteosat
The Meteosat series of satellites are geostationary meteorological satellites operated by EUMETSAT under the Meteosat Transition Programme (MTP) and the Meteosat Second Generation (MSG) program. The MTP program was established to ensure the operational continuity between the end of the successful Meteosat Operational Programme in 1995 and Meteosat Second Generation (MSG), which came into operation at the start of 2004 using improved satellites. The MSG program will provide service until the MTG (Meteosat Third Generation) program takes over. __TOC__ First generation The first generation of Meteosat satellites, Meteosat-1 to Meteosat-7, provided continuous and reliable meteorological observations from space to a large user community. Meteosat-1 to -7 have all now retired. When operational, the Meteosat First Generation provided images every half-hour in three spectral channels (Visible, Infrared) and Water Vapour, via the Meteosat Visible and Infrared Imager (MVIRI) instrum ...

Digital Television
Digital television (DTV) is the transmission of television signals using digital encoding, in contrast to the earlier analog television technology which used analog signals. At the time of its development it was considered an innovative advancement and represented the first significant evolution in television technology since color television in the 1950s. Modern digital television is transmitted in high-definition television (HDTV) with greater resolution than analog TV. It typically uses a widescreen aspect ratio (commonly 16:9) in contrast to the narrower format of analog TV. It makes more economical use of scarce radio spectrum space; it can transmit up to seven channels in the same bandwidth as a single analog channel, and provides many new features that analog television cannot. A transition from analog to digital broadcasting began around 2000. Different digital television broadcasting standards have been adopted in different parts of the world; below are the more widel ...
