Abstract: A basic idea for efficient media communication between two nodes in a group communication system is to set up a number, N, of parallel, separate media streams of the same media type in a given direction between the nodes, where N is equal to or greater than 2. Before setting up the media streams, the actual number of media streams is negotiated (S1). Once the negotiation is completed, the media streams are established (S2). Media data of the same type can then be transferred in parallel, media streams (S3), where each media stream may include media data from a separate source or from a mix of sources. In this way, a richer and/or more personalized rendering of the media data is enabled since media data may be transported as individual media streams and processed locally in a participant, rather than processed and mixed into a single stream by a central mixer.
