Abstract :
TELIDON is a videotex development of the Canadian Department of Communications that differs radically in display presentation format from the earlier European developments. The name videotex is used internationally to represent a class of home and business information services which disseminate information from information suppliers into the home or office. In general, a television receiver, suitably modified or augmented, can serve as the consumer´s terminal equipment. The system essentially makes use of the set as a still-picture display medium where the consumer has control over what is displayed. By utilizing the common-carrier telephone line or other interactive network, or broadcast system, users of the service are able to retrieve information stored in computer controlled databases and have it displayed.
