The invention provides a method for selecting input video signals in a video conference for transmission. The method bases its selection decision on the momentary voice activity of the participants, but does so while observing constraints aimed at: improving stability of the image seen by each participant; decreasing flickering of the image; choosing comfortable and helpful swapping times between different image configurations; and reflecting the importance which is attributed to persons having a higher past average activity in a natural conference. In one embodiment of the invention, the set of constraints includes an override, by which one or more participants can be selected irrespectively of the selection decision. In accordance with a second aspect of the invention, there is provided video selector hardware comprising units to perform the steps of the method. |
