摘要： 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.

摘要： A method and apparatus for recovering a call resource from a call session are disclosed. A call resource detects if a media stream communicated from a device via a communication network becomes inactive during the call session and deletes the inactive media stream. The call resource deletes the inactive media streams until one media stream remains in the call session, which is terminated to release the call resource from the call session.
