/see`-yoo-see'-mee/ ("CU" from Cornell University) A shareware personal computer-based videoconferencing program for use over the Internet, developed at Cornell University, starting in 1992. CU-SeeMe allows for direct audiovisual connections between clients, or, like irc, it can support multi-user converencing via servers (here called "reflectors") to distribute the video and audio signals between multiple clients. CU-SeeMe was the first videoconferencing tool available at a reasonable price (in this case, free) to users of personal computers. Compare with multicast backbone.
