To develop a cost-effective method of sharing educational resources, a dial-up teleconferencing network was implemented between three radiologic sites for a 30-day period of evaluation.
By means of standard dial-up telephone channels, compressed video and audio signals displayed radiologic images, slides, and text, allowing residents and faculty from the three sites to participate in sight and sound interactions.
Each of the three sites used compressed video/audio coderdecoders (codecs) conforming to the Consultative Committee on International Telegraphy and Telephony H.261 standard.
Four video cameras were used at each site, and the audio was run in full duplex mode.
A multipoint video bridge was used to broadcast codec output signals to the input lines of the other codecs.
