A centralized multipoint conferencing arrangement uses a combination of multicast and unicast transmissions that is bandwidth efficient. A method of conferencing includes transmitting multimedia streams from endpoint terminals to a central resource such as a multipoint control unit (MCU) using unicast transmission. The multimedia streams are processed in the MCU and transmitted back to the endpoint terminals using multicast transmission. In addition, the MCU transmits other multimedia streams to selected endpoint terminals using unicast transmission. At the selected endpoint terminals, processing of the multimedia streams is inhibited in favor of processing the other multimedia streams.
