Abstract
Systems and Methods to transmit and simultaneously display all video streams in a video conference by dynamically adapting video streams based on audio volume of the participants include allocating an amount of bandwidth to a participant in a videoconference; determining a level of activity exhibited by the participant during the videoconference, and changing the amount of bandwidth allocated to the participant responsive to the determined level of activity. In another aspect, a method for displaying video streams includes creating a graphical representation of a participant in a videoconference; displaying the created graphical representation; determining a level of activity exhibited by the participant during the videoconference; and altering the displayed graphical representation of the participant responsive to the determined level of activity.
