Abstract: A video conferencing system provides realistic presence of participants in a videoconference by way of standards-based communication. The system includes three large displays, and at least one slave codec and one camera for each display. In addition, there is an extra codec installed which is the master codec. The master codec is able to establish a conference by instructing the slave codecs at its own site and at the other participating sites to set up point-to-point connections with other slave codecs at different participation sites in a pattern providing an optimal feeling of natural communication so that when a user A talk to user B at another site, user B will experience that the user A turns to him.

Abstract: An arrangement and a method of a videoconferencing end-point provide for eye contact between users at different sites. A conference camera is placed in the light beam of a projector apparatus without degrading the camera-captured view by the projector light. This is provided by generating a black spot in the light beam covering the camera lens, and by adjusting the position and/or size of the black spot according to a camera position detector, which may be the camera itself or one or more light sensors around and close to the camera lens.
