Videotex systems

Abstract

Videotex refers to "various computer-based interactive systems that electronically deliver screen text, numbers and graphics via telephone or two-way cable for display on a television set or a video monitor". This technology allows computer-naive users to easily access general interest or highly specialized information stored in on-line databases in the amount and sequence (s)he desires. Over the past decade, there has been considerable interest in videotex systems, and a number of them have already been implemented in different countries. With the proposed implementation of Integrated Services Digital Networks, the interest in videotex systems is expected to grow even further.This paper provides a brief overview of commercial videotex systems in various countries, and discusses possible organizational usage of these systems. In addition, this paper discusses design issues considered central to the development of a geographically dispersed videotex systems. Currently available solution procedures for addressing these design issues are also suggested.
