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.

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] |
BBC Red Button
BBC Red Button is a brand used for digital interactive television services provided by the BBC, and broadcast in the United Kingdom. The services replaced Ceefax, the BBC's analogue teletext service. BBC Red Button's text services were due to close on 30 January 2020, but the switch off was suspended on 29 January 2020 following protests. History and branding The service was launched on 23 September 1999 as BBC Text. It was relaunched in November 2001 under the BBCi brand and operated under this name until late 2008, when it was rebranded as BBC Red Button. The "red button" name refers to the common interface on remote controls for digital televisions and set-top boxes, a red push-button that launches digital teletext services. Although initially marketed as a spectacular new form of television, by 2008 this had given way to positioning iTV as ‘everyday’. This was due in part to the institutional landscape of television in the UK. In September 2009, the BBC celebrated 10 y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antiope (teletext)
Antiope was a French teletext standard in the 1980s. It also formed the basis for the display standard used in the French videotex service Minitel. The term allegedly stood for ''Acquisition Numérique et Télévisualisation d’Images Organisées en Pages d’Écriture'', which could be loosely translated as ''Digital Acquisition and Remote Visualization of Images Organized into Written Pages''. Work on Antiope started in 1972 at CCETT, the newly merged French national research centre for television and telecommunications in Rennes, with first field trials in 1975. The system was officially launched in 1976 at Vidcom in Cannes, and simultaneously at the СПОРТ 76 exposition in Moscow. It was adopted into the international standard CCIR 653 (now ITU-R BT.653) of 1986 as CCIR Teletext System A. Antiope ceased to be used for broadcast teletext in the early 1990s, before teletext became popular in France. It was replaced by European standard World System Teletext. However, ...

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] |

Prestel
Prestel (abbrev. from press telephone), the brand name for the UK Post Office Telecommunications's Viewdata technology, was an interactive videotex system developed during the late 1970s and commercially launched in 1979. It achieved a maximum of 90,000 subscribers in the UK and was eventually sold by BT in 1994. The technology was a forerunner of on-line services today. Instead of a computer, a television set connected to a dedicated terminal was used to receive information from a remote database via a telephone line, although a computer with a modem and running Terminal emulator software can be used if the user so inclined. The service offered thousands of pages ranging from consumer information to financial data but with limited graphics. Initial development Prestel was created based on the work of Samuel Fedida at what was then known as the Post Office Research Station in Martlesham, Suffolk. In 1978, under the management of David Wood the software was developed by a tea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World System Teletext
World System Teletext (WST) is the name of a standard for encoding and displaying teletext information, which is used as the standard for teletext throughout Europe today. It was adopted into the international standard ITU-R, CCIR 653 (now ITU-R BT.653) of 1986 as CCIR Teletext System B. Development WST originally stems from the UK standard developed by the BBC and the UK Independent Broadcasting Authority in 1974 for teletext transmission, extended in 1976 as the Broadcast Teletext Specification. With some tweaks to allow for alternative Teletext character set, national character sets, and adaptations to the NTSC 525-line system as necessary, this was then promoted internationally as "World System Teletext". It was accepted by ITU-R, CCIR in 1986 under international standard CCIR 653 (now ITU-R BT.653) as one of four recognised standards for teletext worldwide (most commonly referred to as CCIR Teletext System B). WST in Europe Almost all television sets sold in Europe since the e ... [...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] |
