CEPT4
CEPT Recommendation T/CD 06-01 was a standard set in 1981 by the European Conference of Postal and Telecommunications Administrations (CEPT) for the display of Videotex; specifically, for the ''Videotex Presentation Layer Data Syntax''. It was revised a number of times in the 1980s, and also later redesignated as recommendation T/TE 06-01. The standard aimed to bring a degree of harmonisation between Europe's emerging videotex systems, which had been diverging along national lines. It recognised four baseline profiles (with conformance criteria set out in Annex C) based on existing videotex services: * CEPT1: BTX (Germany) * CEPT2: Teletel (France) * CEPT3: Prestel (UK) * CEPT4: Prestel Plus (Sweden) and defined criteria for a "harmonised enhanced" service. National videotex services were encouraged to either follow one of the existing four basic profiles; or if they extended them, to do so in ways compatible with the harmonised enhanced specification.

Videotex
Videotex (or interactive videotex) was one of the earliest implementations of an end-user information system. From the late 1970s to early 2010s, it was used to deliver information (usually pages of text) to a user in computer-like format, typically to be displayed on a television or a dumb terminal. In a strict definition, videotex is any system that provides interactive content and displays it on a video monitor such as a television, typically using modems to send data in both directions. A close relative is teletext, which sends data in one direction only, typically encoded in a television signal. All such systems are occasionally referred to as ''viewdata''. Unlike the modern Internet, traditional videotex services were highly centralized. Videotex in its broader definition can be used to refer to any such service, including teletext, the Internet, bulletin board systems, online service providers, and even the arrival/departure displays at an airport. This usage is no longe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Conference Of Postal And Telecommunications Administrations
The European Conference of Postal and Telecommunications Administrations (CEPT) was established on June 26, 1959, by nineteen European states in Montreux, Switzerland, as a coordinating body for European state telecommunications and postal organizations. The acronym comes from the French version of its name ''Conférence européenne des administrations des postes et des télécommunications''. CEPT was responsible for the creation of the European Telecommunications Standards Institute (ETSI) in 1988. CEPT is organised into three main components: * Electronic Communications Committee (ECC) - responsible for radiocommunications and telecommunications matters and formed by the merger of ECTRA (European Committee for Telecommunications Regulatory Affairs) and ERC (European Radiocommunications Committee) in September 2001 **The permanent secretariat of the ECC is the European Communications Office (ECO) * European Committee for Postal Regulation (CERP, after the French ''"Com ...

Bildschirmtext
Bildschirmtext (German "screen text", abbrev. Btx or BTX) was an online videotex system launched in West Germany in 1983 by the Deutsche Bundespost, the (West) German postal service. Btx originally required special hardware (it was based on GEC 4000 series computers) which had to be bought or rented from the British General Post Office. The data was transmitted through the telephone network using V.23 modems and the content was displayed on a television set. History Originally conceived to follow the UK Prestel specifications, and developed on contract by a small UK company called Systems Designers Ltd (originally merged into EDS and now part of HP) for IBM Germany. Btx added a number of additional features before launch, including some inspired by the French Minitel service, to create a new display standard of its own, which in 1981 was designated the CEPT1 profile. The system was presented at the IFA in Berlin, with a trial system installed in Düsseldorf and Berlin i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teletel
The Minitel was a videotex online service accessible through telephone lines, and was the world's most successful online service prior to the World Wide Web. It was invented in Cesson-Sévigné, near Rennes in Brittany, France. The service was rolled out experimentally on 15 July 1980 in Saint-Malo, France, and from autumn 1980 in other areas, and introduced commercially throughout France in 1982 by the PTT ( Postes, Télégraphes et Téléphones; divided since 1991 between France Télécom and La Poste)."Minitel: The rise and fall of the France-wide web" Hugh Schofield, ''BBC News Magazine'' (Paris), 27 June 2012.

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] |

European Telecommunications Standards Institute
The European Telecommunications Standards Institute (ETSI) is an independent, not-for-profit, standardization organization in the field of Information and communications technology, information and communications. ETSI supports the development and testing of global technical standards for ICT-enabled systems, applications and services. Overview ETSI was set up in 1988 by the European Conference of Postal and Telecommunications Administrations (European Conference of Postal and Telecommunications Administrations, CEPT) following a proposal from the European Commission. ETSI is the officially recognized body with a responsibility for the standardization of Information and Communication Technologies (ICT). It is one of the three bodies, the others being European Committee for Standardization, CEN and CENELEC, officially recognized by the European Union as a European Standards Organization (ESO). The role of the European Standards Organizations is to support EU regulation and poli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
