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] |
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.

Minitel
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 (France), Postes, Télégraphes et Téléphones; divided since 1991 between Orange S.A., France Télécom and La Poste (France), La Poste)."Minitel: The rise and fall of the France-wide web" Hugh Schofield, ''BBC News Magazine'' (Paris), 27 June 2012.

T-Online
t-online.de is a German news portal, owned and published by digital multi-channel media company Ströer. It reaches over 179 million visits per month coming from 29 million unique visitors. The editorial team is located in Berlin. History In 1995 Deutsche Telekom renamed the ''Bildschirmtext'' (BTX) service as "T-Online". In Spring 2000, T-Online became the first major ISP in Germany to offer a flat-rate dialup plan for consumers. This was important because local telephone calls in Germany, including dialup access to ISPs, were not offered on a flat price per call (i.e., unlimited) basis. The flat-rate service was also offered to customers with ISDN connections at the same price as for analog service. In spring 2001, T-Online announced the demise of the flat-rate dialup plan but offered a flat-rate DSL plan in its place. Deutsche Telekom (T-Online) was the monopoly Internet Service Provider (ISP) for the German Internet until its privatization Privatization (also pri ...

CEPT1
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.

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] |

A system, surrounded and influenced by its environment, is described by its boundaries, structure and purpose and expressed in its functioning. Systems are the subjects of study of systems theory and other systems sciences. Systems have several common properties and characteristics, including structure, function(s), behavior and interconnectivity. Etymology The term ''system'' comes from the Latin word ''systēma'', in turn from Greek ''systēma'': "whole concept made of several parts or members, system", literary "composition"."σύστημα" Henry George Liddell, Robert Scott, '' |
Hewlett-Packard

Berlin
Berlin ( , ) is the capital and largest city of Germany by both area and population. Its 3.7 million inhabitants make it the European Union's most populous city, according to population within city limits. One of Germany's sixteen constituent states, Berlin is surrounded by the State of Brandenburg and contiguous with Potsdam, Brandenburg's capital.

Düsseldorf
Düsseldorf ( , , ; often in English sources; Low Franconian and Ripuarian: ''Düsseldörp'' ; archaic nl, Dusseldorp ) is the capital city of North Rhine-Westphalia, the most populous state of Germany. It is the second-largest city in the state and the seventh-largest city in Germany, with a population of 617,280. Düsseldorf is located at the confluence of two rivers: the Rhine and the Düssel, a small tributary. The ''-dorf'' suffix means "village" in German (English cognate: ''thorp''); its use is unusual for a settlement as large as Düsseldorf. Most of the city lies on the right bank of the Rhine. Düsseldorf lies in the centre of both the Rhine-Ruhr and the Rhineland Metropolitan Region. It neighbours the Cologne Bonn Region to the south and the Ruhr to the north. It is the largest city in the German Low Franconian dialect area (closely related to Dutch). Mercer's 2012 Quality of Living survey ranked Düsseldorf the sixth most livable city in the world.

German Reunification
German reunification (german: link=no, Deutsche Wiedervereinigung) was the process of re-establishing Germany as a united and fully sovereign state, which took place between 2 May 1989 and 15 March 1991. The day of 3 October 1990 when the German Reunification Treaty entered into force dissolving the German Democratic Republic (GDR; german: link=no, Deutsche Demokratische Republik, DDR, or East Germany) and integrating its recently re-established constituent federated states into the Federal Republic of Germany (FRG; german: link=no, Bundesrepublik Deutschland, BRD, or West Germany) to form present-day Germany, has been chosen as the customary ''German Unity Day'' () and has thereafter been celebrated each year from 1991 as a national holiday. East and West Berlin were united into a single city and eventually became the capital of reunited Germany. The East Germany's government led by the Socialist Unity Party of Germany (SED) (a communist party) started to falter on 2 May 1 ...
