Abstract
A remote conferencing system. Prior to a conference, visual images are distributed to computers of conference participants. Also, conference participants are supplied with pictures of all other participants. During the conference, one participant, a leader, periodically issues selection signals to all computers, causing them all to select one of the distributed images, and display it. In addition, the participants hold a telephone conference while viewing the images. The selection signals and the telephone conference are carried by a single voice-grade telephone channel.
