ABSTRACT:
In making a transition from two-point communication to three-point communication, by making preparations for three-point communication without interrupting two-point communication, and by making a transition to three-point communication when preparations are completed, momentary interruption of the conversation is eliminated. That is, while maintaining two-point communication, the transcoders at each point are made to acquire rate control information for all points, after which the transition to three-point communication is made.
