Enhancement of the Shared Graphics Workspace.

Abstract

The Shared Graphic Workspace (SGWS) is part of a two-node video-teleconferencing system, developed by CSM under DARPA auspices, that links the United Stated Air Force/Foreign Technology Division (AF/FTD), in Dayton, Ohio, with another U.S. government site, in Maryland. It transmits black-and-white images via the CLI 19.2 kilobits-per-second (kbps) Sketch Coders; uses TSP-2000 voice codecs (coders/decoders), operating at 4.8 kbps, for the audio connection; and allows teleconference participants to share and annotate information sent via the SGWS. This report discusses software and hardware enhancements that CSM is making to the SGWS. The enhancements include upgrading the UNIX 6.0 operating system to Ultrix, a variation of the Berkeley UNIX, and improving the hardcopy capabilities of the SGWS by adding the Datacopy Digital camera and the Apple Laserwriter.
