ABSTRACT:
Marking a keyframe of a media stream in a communication system involves one or more entry media switches in communication with one or more endpoints. An entry media switch receives a media stream from an endpoint, where the media stream comprises a sequence of packets with a keyframe. The keyframe is detected and marked with a keyframe indicator. The keyframe indicator is operable to notify a downstream device of the keyframe. An output media stream is outputted.
