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, ...

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 vide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ISO/IEC 646
ISO/IEC 646 is a set of ISO/ IEC standards, described as ''Information technology — ISO 7-bit coded character set for information interchange'' and developed in cooperation with ASCII at least since 1964. Since its first edition in 1967 it has specified a 7-bit character code from which several national standards are derived. ISO/IEC 646 was also ratified by ECMA as ECMA-6. The first version of ECMA-6 had been published in 1965, based on work the ECMA's Technical Committee TC1 had carried out since December 1960. Characters in the ISO/IEC 646 Basic Character Set are ''invariant characters''. Since that portion of ISO/IEC 646, that is the ''invariant character set'' shared by all countries, specified only those letters used in the ISO basic Latin alphabet, countries using additional letters needed to create national variants of ISO/IEC 646 to be able to use their native scripts. Since transmission and storage of 8-bit codes was not standard at the tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Teletext Services
Teletext (or "broadcast teletext") is a television information retrieval service developed in the United Kingdom in the early 1970s. It offers a range of text-based information, typically including national, international and sporting news, weather and TV schedules. Subtitle (captioning), Subtitle (or closed captioning) information is also transmitted in the teletext signal, typically on page 888 or 777. A number of similar teletext services were developed in other countries, some of which attempted to address the limitations of the British-developed system, with its simple graphics and fixed page sizes. This is an incomplete list of teletext services available on different television channels around the world: Countries with functioning teletext services Albania * Top-Channel * TVSH * Mediaset * RAI Austria * ORF Text (ORF1, ORF2, ORF3) * ORF Sport Text (ORF Sport Plus) * TW1 Text (TW1 (Austria), TW1) * 3satText (3sat) * ATV TEXT (ATV (Austria), ATV) * Puls 4 Text (Puls 4) * S ...

NAPLPS
NAPLPS (North American Presentation Level Protocol Syntax) is a graphics language for use originally with videotex and teletext services. NAPLPS was developed from the Telidon system developed in Canada, with a small number of additions from AT&T Corporation. The basics of NAPLPS were later used as the basis for several other microcomputer-based graphics systems. History The Canadian Communications Research Centre (CRC), based in Ottawa, had been working on various graphics systems since the late 1960s, much of it led by Herb Bown.Cynthia Boyko"Telidon" Friends of the CRC, 14 October 1997 Through the 1970s they turned their attention to building out a system of "picture description instructions", which encoded graphics commands as a text stream. Graphics were encoded as a series of instructions (graphics primitives) each represented by a single ASCII character. Graphic coordinates were encoded in multiple 6-bit strings of XY coordinate data, flagged to place them in the print ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JTES
JTES, the Japanese Teletext Specification, is a protocol used for encoding teletext pages, as well as other types of digital data, within the vertical blanking interval (VBI) of an analog video signal in Japan. It was adopted into the international standard CCIR 653 (now ITU-R BT.653) of 1986 as CCIR Teletext System D. It supports the display of Chinese, Katakana and Hiragana characters. The service can be used to display subtitles, cyclic text pages or pseudo interactive programs. There's support for presentation of photographs, geometry or sound. History The development of teletext in Japan started in 1972, followed by the announcement of the world's first teletext system (Ceefax) by the BBC in the United Kingdom. Because Japanese characters are different from the western alphabets, Japan proceeded with research and development of a specific transmissions method. Called ''"pattern method"'', it sends scanning signals similar to a fax, at a rate 20 times faster than existing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NABTS
NABTS, the North American Broadcast Teletext Specification, is a protocol used for encoding NAPLPS-encoded teletext pages, as well as other types of digital data, within the vertical blanking interval (VBI) of an analog video signal. It is standardized under standard EIA-516, and has a rate of 15.6 kbit/s per line of video (with error correction). It was adopted into the international standard CCIR 653 (now ITU-R BT.653) of 1986 as CCIR Teletext System C. History NABTS was originally developed as a protocol by the Canadian Department of Communications, with their industry partner Norpak, for the Telidon system. Similar systems had been developed by the BBC in Europe for their Ceefax system, and were later standardized as the World System Teletext (WST, aka CCIR Teletext System B), but differences in European and North American television standards and the greater flexibility of the Telidon standard led to the creation of a new delivery mechanism that was tuned for speed.

SCART
SCART (also known as or , especially in France, 21-pin EuroSCART in marketing by Sharp in Asia, Euroconector in Spain, EuroAV or EXT, or EIA Multiport in the United States, as an EIA interface) is a French-originated standard and associated 21-pin connector for connecting audio-visual (AV) equipment. The name SCART comes from , "Radio and Television Receiver Manufacturers' Association", the French organisation that created the connector in the mid-1970s. The related European standard EN 50049 has then been refined and published in 1978 by CENELEC, calling it ''péritelevision'', but it is commonly called by the abbreviation ''péritel'' in French. The signals carried by SCART include both composite and RGB (with composite synchronisation) video, stereo audio input/output and digital signalling. The standard was extended at the end of the 1980s to support the new S-Video signals. A TV can be woken from standby mode and automatically switch to the appropriate AV channel wh ...
