ABSTRACT:
Method and apparatus for Real Time protocol mixer traversal. Data including at least one feedback component are transmitted from a first to a second node. The feedback component is transmitted to the first node. Alternatively, a method includes transmitting Real Time Protocol data to a mixer from a first and a second node participating in a real time communications session. The mixer has a first feedback decoupling and a second feedback decoupling array. A feedback stream is sent from the first node and the second node to the mixer. The first and second feedback stream are responsive to the mixed stream. The first and second feedback stream are separated into a first and a second feedback component part. The first part is associated with Real Time Protocol information received from the first node. The second feedback component is representative of the information received from the second node. The first and second feedback component parts are combined into a plurality of feedback streams comprising the feedback components. The mixer feedback streams are transmitted to the nodes. A communications system includes a first and a second node. Data is transmitted from the first to the second node. A mixer receives feedback including at least one feedback component. The feedback component is transmitted to the first node and is responsive to the real time data received by the second node.
