发明名称 Videoconference system
摘要 A video-conferencing system between participants located at distant sites, each site featuring a viewing screen. The viewing screen is a large screen of the projection, overhead projection, or direct projection type which has one or more viewing systems forming an image wall to simultaneously view all the distant participants within a space reproduced on the image wall formed by the screen. The system includes devices for each site that spatially distribute the sound to match the sound generated by each distant participant and the image of the participant projected on the screen at the site considered.
