摘要： The present invention relates to a video conference system (SC, SE, VI) comprising at least one visual scan means (SC), a mediating Server entity (SE) and a at least one visual presentation means (VI) for presenting a scanned perspective view connected via a network, where the visual scan means (SC) comprises change means for changing the perspective view, and the video conference system (SC, SE, VI) comprises further mediating means (SE), storage means (MO), and control means that are adapted to process individual visual perspectives for the at least one visual presentation means, where the mediating means are adapted to aggregate multiple scanned views, where the storage means buffer the aggregate multiple scanned views, where the control means are adapted to instruct the change means for selecting a scan perspective, and where retrieval means are adapted to extract a requested individual perspective view out of the aggregated multiple scanned views. The invention further relates to a mediating media server, a client device, a computer software product, and a method for providing an individual perspective view for a participant of a videoconference between multiple participants.
