Title: Videotex: The new information systems
Author(s): Veith, Richard H.
Subject(s): Libraries --Automation Library science --Data processing Information technology
Abstract: Videotex and teletext are terms that are becoming harder and harder to define, and it is usually necessary to begin by explaining what the terms originally meant. Videotex has been used to refer to computerized information/ entertainment systems using telephone lines to tie home television sets to computers. Teletext has been used to refer to computerized information/ entertainment systems that send data to home television sets by encoding the data into unused portions of a television signal. At the receiving end the television set both videotex and teletext can look identical. And both, from the beginning, employed color and graphics as distinguishing characteristics. However, both systems are still evolving technically and conceptually. Newer systems have been developed (for example, on cable television installations) which incorporate a little bit of both, as well as features of traditional timesharing computer systems. In many cases, the term videotex is used to refer to all of these systems that are designed to bring digital data to television sets or television monitors, usually using color and graphics.
