This ERIC digest provides a brief overview of the video, audio, and computer technologies that are currently used to deliver instruction for distance education programs. The video systems described include videoconferencing, low-power television (LPTV), closed-circuit television (CCTV), instructional fixed television service (ITFS), and cable television (CATV). Several types of audiographic teleconferencing are then described, including telefacsimile (FAX), freeze-frame or slow scan video, and compressed video. Audioconferencing is cited as the principal use of audio telephone delivery, but it is noted that other options are also available, including the use of an audio bridge to enable two-way interaction among groups at three or more locations. Computer conferencing options are also described, including electronic mail networks, electronic bulletin board services (BBSs), and teletext and videotex. A brief discussion of distance education concludes the digest. (14 references) (EW)
