Part of Norpak Information Provider System (IPS)-2 Designed, developed & built in Canada as par to 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

A table used as a work station to for an Information Provider System 2 (IPS-2) system. It allows components to be bolted into an equipment rack and monitors and a keyboard to be used on the table surface. Attached to this table are 1987.0953.5 - .7, and a PDP 11/03 computer. The PIS-2 was a picture creation system used for Telidon. Page creation systems were meant to be used by professional artists hired by service providers to create and provide content for Telidon system databases, often in the form of commercial art.

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 IPS-2 system to create a graphical image, which software then converted into picture description instructions which 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.
