Abstract
In one embodiment, a method includes dropping an initial series of video frames received by a video conferencing system from a first endpoint that has entered a video conference session as a first participant. One or more fast video update (FVU) messages received by the video conferencing system from the first endpoint during an enabling time period are then discarded. A single FVU message is then to the first endpoint after the video conferencing system has become enabled with respect to the first endpoint. An I-frame received from the first endpoint in response to the single FVU message is then sent back to the first endpoint. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.
