Part of Norpak Information Provider System (IPS)-2 designed, developed & built in Canada as part of the Telidon system. The Telidon program began on August 15, 1978 and ended on March 31, 1985. The Information Provider System 2 (IPS-2) systems were purchased by service providers, like Informart, and made available to professional artists use to create content for Telidon field trails. This example was used by the National Museum of Science and Technology. - Fonction
-
This Norpak D3665 R2 display processor converted code into an image. It was part of an Information Provider System 2 (IPS-2) system which was used to create Telidon graphic images. - Technique
-
The images created for the Telidon System needed to be transmitted via a 1200 baud modem over narrow bandwidth telephone line. Accordingly, it was important for designers to make sure the system used a very small amount of data. The was especially the case as research conducted by Communications Research Center psychologists had determined that the system needed to be able to load images in about under 20 seconds as, otherwise, users would lose patience. Designers therefore worked to create a fairly efficient encoding and to get the number of bytes per page down, their target being the 1 to 2 kilobyte range. The system used a PDP 11 computer, a decoder and a floppy disk drive. The PDP 11 computer was an early version of the smallest of the mini computers, and contributed to the IPS-2 high cost. A professional artist would use the station, including this display processor, to create a graphical image, which software then converted into picture description instructions that could be uploaded to a central database, transmitted via a network, received and converted into something displayable on a home television screen by a decoder. While the IPS-2 system was very expensive, according to Douglas O'Brien, it did a great job at creating images for the Telidon system. 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. - Notes sur la région
