Claim:
1. A computer implemented method for creating a video image for display on at least one client within a multiparty video conferencing system, the client comprising one or more graphical user interfaces, the video data stream created to meet the perceptual requirements of a viewer within a virtual environment representing the video conferencing system, comprising the steps of: at a processor, receiving a first client video image, associated with a first client in the multiparty video conferencing system; receiving spatial coordinates of a video surface associated with the first client within the virtual environment; receiving from a viewer client spatial coordinates of a viewpoint associated with the viewer client within the virtual environment; spatially degrading the video image in dependence on the positions and orientations of the viewpoint and the video surface within the virtual environment, the step of spatially degrading the video image is performed by: transmitting the degraded video stream to the viewer client for display within the virtual environment; and receiving updated spatial coordinates and updating the spatial degradation of the video image in dependence on the updated spatial coordinates.
