Abstract
A teleconferencing apparatus and system consisting of a unitary housing. The housing includes audio and video capture capabilities for capturing video images and spoken audio of a participant in a videoconference; a monitor for displaying visual images associated with at least one participant; audio and reproduction capabilities; and an adaptive acoustic echo canceler to reduce echo during the reproduction of audio. A plurality of the apparatuses are distributed in the system and interconnected by a first network and a second network. The first network provides an AV path along which AV signals, representing video images and spoken audio of the participants can be carried while the second network provides a data path along which data can be shared among a plurality of participants. The system may also include two monitors, one for displaying the video images of the participants and the other for displaying data shared among the participants.
