Abstract

Method and system for video conferencing with at least three different video conference participant stations, which communicate with one another by a telecommunications network. Multimedia data is transmitted over the telecommunications network including at least participant image data and/or participant audio data, and each participant receives the participant image data of the other participants shown at the same time visually arranged on a reproduction device. An eye tracking system registers the direction of view of the respective participant and transmits it to a communications unit. Those participant image data which are not shown in the momentary direction of view of the respective participant are transmitted over the telecommunications network to the communications unit with reduced resolution and/or video transmission rate.
