Abstract
In some embodiments, a videoconferencing endpoint may be an MCU (Multipoint Control Unit) or may include embedded MCU functionality. In various embodiments, the endpoint may thus conduct a videoconference by receiving/compositing video and audio from multiple videoconference endpoints. The endpoint may select a subset of endpoints and form a composite video image from the subset of the videoconference endpoints to send to the other videoconference endpoints. In some embodiments, the subset of endpoints that are selected for compositing into the composite video image may be selected according to criteria such as the last N talking participants. In some embodiments, the master endpoint may request the non-talker endpoints to stop sending video to help conserve the resources on the master endpoint. In some embodiments, the master endpoint may ignore video from endpoints that are not being displayed.
