Description
Summary:Within the last few years videotex has attracted considerable attention. Unfortunately, but as frequently is the case with novel services that are still evolving, a precise definition of videotex is somewhat difficult to obtain. To some people the term videotex applies to a wide variety of time-shared computer services for the home and business market, while to others, the term videotex is very specific perhaps best exemplified by the UK Prestel service. In its most narrow and specific meaning, videotex is a subset of online, time-shared computer services. It utilizes the home TV set for display to access a large, central database of frames of general information in colour with graphics. The database is organized in a tree fashion, and the main target is the home market.
