Période

IF USED - AT NMST OTTAWA, CA. 1983

Canada

Part of videotex technology system designed, developed & built in Canada by the Communications Research Centre. The Telidon program began on August 15, 1978 and ended on March 31, 1985. Artefact was purchased by the National Museum of Science and Technology on October 28th, 1982 as operational equipment for $4050. The object was wither used very little or never used.

Fonction

The Hemton EPS 1 was an electronic projector system use to decode, demonstrate and display Telidon graphic images onto a color monitor in areas like shopping malls or businesses.

Technique

The Hempton EPS 1 model is an early Telidon decoder that was used & current in 1982. It used a microprocessor and a 1200 baud modem to decode and convert communications data code to something that was displayable on a television display screen. This decoder used a bit plane that is a dot by dot image structure. While the graphic was not high quality, it was quite reasonable and the code was designed to be capable of expanding to handle higher resolutions. The system was designed to be forward and backward compatible, meaning it had the capability of displaying existing and future images, taking advantage of lowering memory costs to improve Telidon technology over time. According to Douglas O’brien, this is essentially a Norpak terminal with memory. It was possible to load and cycle trough data, projecting Telidon graphics. This technology was meant for a different market as it was designed for presentations and displays in places like shopping malls. In 1983, the North American Presentation Level Protocol Syntax (NAPLPS) graphics language develop from the Canadian Telidon system was formalized, ratified and adopted as a world standard for graphics transmission by computer.
