An audio-graphics teleconferencing system has been developed that uses ordinary personal computers interconnected over a basic rate (2B+D) ISDN line. The system supports high-speed transmission of 200-dpi resolution documents read in by an optical scanner and presented on the displays of the conference participants. While looking at the same material, the conferees can interactively converse and make handwritten notations on the document via an LCD tablet for all the participants to see. We describe the configuration and performance of the system, focusing mainly on the ISDN based multimedia transmission method and the method for reducing and enlarging binary images.
