Abstract
A method and apparatus of providing a back-channel for a receiver terminal in a loosely-coupled conference is described. The loosely-coupled conference includes at least one receiver terminal and a H.323 panel having a multipoint controller with a multipoint address and one or more H.323 terminals coupled to the multipoint controller and each to transmit and receive media streams on a multicast address. The method includes the steps of receiving media streams of the one or more H.323 terminals on the multicast address by the receiver terminal, connecting to the multipoint controller by using the multipoint address, and joining the H.323 panel to transmit and receive media streams on the multicast address for establishing bi-directional communication with the one or more H.323 terminals.
