TELETEXT SYSTEMS - CONSIDERING THE PROSPECTIVE USER

An overview of teletext systems is given, stressing in particular the viewpoint of the potential user. The expected reaction of the North American consumer to teletext is analyzed. Such a forecast is important because a consumer teletext system has not yet been implemented in North America. Although teletext has many potential categories of users and can be implemented in many different ways, this paper concentrates on broadcast teletext as an ancillary service for consumers. The analysis is based on considerations of technical feasibility and the constraints imposed by consumer behavior. The results of this analysis have important implications on system design.
