Abstract
An automatic switching system and method for determining and effecting an optimal video display mode based on the interaction among participants in a conference or discussion is disclosed. The system includes a timer which continuously monitors the duration of signals received from each of a number of endpoints. The system further includes a signal switching processor which compares the signal durations to predefined parameters which define various display mode switching thresholds. The system reacts to the conversational interaction of endpoint participants by automatically switching the display mode of all endpoints between single-window, single speaker presentation mode, and multiple-window, multiple speaker discussion mode.
