Abstract
A media relay conferencing system includes a media relay multipoint control unit and a media relay endpoint that handle needs for Intra frames in an efficient way, improves the conferees experience, and reduces the load on the resources associated with that media relay videoconference by reducing the number of Intra frames and lowering the impact of Intra frames when they are needed. In some embodiments, when a requiring media relay endpoint requests an Intra frame for a video stream received from a presenting media relay endpoint, a media relay multipoint control unit may respond by requesting the presenting media relay endpoint to synchronize a reference frame in an encoder of the presenting media relay endpoint, which encodes the relevant relay compressed video stream, with a reference frame in a decoder of the requiring media relay endpoint.
