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] |
Prestel
Prestel was the Brand#Brand names and trademark, brand name of a videotex service launched in the UK in 1979 by BT Group#Post Office Telecommunications, Post Office Telecommunications, a division of the British Post Office Limited#History, Post Office. It had around 95,500 attached terminals at its peak, and was a forerunner of the internet-based online services developed in the late 20th and early 21st centuries. Prestel was discontinued in 1994 and its assets sold by BT Group, British Telecom to a company consortium. A subscriber to Prestel used an adapted TV set with a keypad or keyboard, a dedicated terminal, or a microcomputer to interact with a central database via an ordinary Telephone line, phoneline. Prestel offered hundreds of thousands of pages of general and specialised information, ranging from consumer advice to financial data, as well as services such as home banking, online shopping, travel booking, telesoftware, and messaging. In September 1982, to mark I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telidon
Telidon (from the Greek words τῆλε, ''tele'' "at a distance" and ἰδών, ''idon'' "seeing") was a videotex/teletext service developed by the Canada, Canadian Communications Research Centre Canada, Communications Research Centre (CRC) during the late 1970s and supported by commercial enterprises led by Infomart in the early 1980s. Most work on the system ended after 1985, having failed to build critical mass. The CRC referred to Telidon as a "second generation" videotex system, offering improved performance, 2D colour graphics, multilingual support and a number of different interactivity options supported on various hardware. With additional features added by AT&T Corporation, and 16 other contributors in North America and supported by the Federal Government, Telidon was redefined as a protocol and became the NAPLPS standard. A number of Telidon systems were rolled out, including GRASSROOTS for the Province of Manitoba, SOI for Venezuela, Compuserve, LA Times in Californi ...

Minitel
The Minitel, officially known as TELETEL, was an interactive videotex online service accessible through telephone lines. It was the world's first and most successful mass-market online service prior to the World Wide Web. It was developed in Cesson-Sévigné, Brittany, by government-owned France Télécom. The service was initially launched on an experimental basis on 15 July 1980 in Saint-Malo and extended to other regions in autumn 1980. It was commercially introduced throughout France in 1982 by the PTT (Postes, Télégraphes et Téléphones; since 1991, divided into 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.

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''. History 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. Commercial broadcasting of Antiope began on Antenne 2 in 1979. To publicise the service, pages were even transmitted ''en clair'' instead of the test card (compare the BBC ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorola 6809
The Motorola 6809 ("''sixty-eight-oh-nine''") is an 8-bit microprocessor with some 16-bit features. It was designed by Motorola's Terry Ritter and Joel Boney and introduced in 1978. Although source compatible with the earlier Motorola 6800, the 6809 offered significant improvements over it and 8-bit contemporaries like the MOS Technology 6502, including a hardware multiplication instruction, 16-bit arithmetic, system and user stack registers allowing re-entrant code, improved interrupts, position-independent code, and an orthogonal instruction set architecture with a comprehensive set of addressing modes. The 6809 was among the most powerful 8-bit processors of its era. It was also among the most expensive; in 1981 single-unit quantities were compared to for a Zilog Z80 and for a 6502. It was launched when a new generation of 16-bit processors were coming to market, like the Intel 8086, and 32-bit designs were on the horizon, including Motorola's own 68000. It was not feature ...

Teletext
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 display units to provide closed captioning to television shows for the hearing impaired. Public teletext information services were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Closed Captioning
Closed captioning (CC) is the process of displaying text on a television, video screen, or other visual display to provide additional or interpretive information, where the viewer is given the choice of whether the text is displayed. Closed captions are typically used as a transcription of the audio portion of a program as it occurs (either verbatim or in edited form), sometimes including descriptions of non-speech elements. Other uses have included providing a textual alternative language translation of a presentation's primary audio language that is usually burned-in (or "open") to the video and unselectable. HTML5 defines subtitles as a "transcription or translation of the dialogue when sound is available but not understood" by the viewer (for example, dialogue in a foreign language) and captions as a "transcription or translation of the dialogue, sound effects, relevant musical cues, and other relevant audio information when sound is unavailable or not clearly audible" (fo ...

Viewdata Graphics 1
Viewdata is a Videotex implementation. It is a type of information retrieval service in which a subscriber can access a remote database via a common carrier channel, request data and receive requested data on a video display over a separate channel. Samuel Fedida, who had the idea for Viewdata in 1968, was credited as inventor of the system which was developed while working for the British Post Office which was the operator of the national telephone system. The first prototype became operational in 1974. The access, request and reception are usually via common carrier broadcast channels. This is in contrast with teletext. Design Viewdata offered a display of 40×24 characters, based on ISO 646 (IRV IA5) – 7 bits with no accented characters. Originally, Viewdata was accessed with a special purpose terminal (or emulation software) and a modem running at ITU-T V.23 speed (1,200 bit/s down, 75 bit/s up). By 2004, it was normally accessed over TCP/IP using Viewdata client ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
