Systems for over-the-air or wired distribution of textual and/or graphic information. This term is usually used to include both teletext and viewdata systems.
A form of electronic publishing consisting of computer-generated text distributed through telecommunications and received and viewed on home television.
An electronic textual information distribution system, from a central computer to remote VDUS. (Also See Teletext, Viewdata).
Interactive (two-way) system for accessing written and graphic information on video screens and computer display terminals, which are linked to central computers via telephone lines.
A service similar to teletext except that information is delivered by telephone channels and a user can interact with the data base to select information for viewing
Term invented by the ITU to describe TV equipment used to display computer-based data, whether sent via a telephone (often called viewdata) or a broadcasting charnel (Teletext). ITU distinguishes between interactive or broadcast videotex.
Describes TV equipment used to display computer-based data, whether this comes to the set vie a telephone (sometimes known as viewdata) or via a broadcasting channel (otherwise known as Teletext).
The generic term used to refer to a 2-way interactive system for the delivery of computer-generated data into the home, usually using the television set as a display device. Some of the more often used specific terms are "viewdata" for telephone-based systems (narrowband interactive systems); "wideband broadcast" or "cabletext" for systems utilizing a full video channel for information transmission; and "wideband 2-way teletext" for systems which could be implemented over 2-way cable television systems. In addition, hybrids and other transmission technologies, such as satellite, could be used for delivery of videotex services on a national scale.
From the late 1970s to mid-1980s, Videotex as one of the earliest implementations of "end-user information systems", delivers information (usually pages of text) to a user in computer-like format, typically to be displayed on a television .
