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 ForceForeign Technology Division AFFTD, 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 codersdecoders, 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.
