Abstract
A conferencing server () receives incoming bitstreams (I, I, I, I, I) carrying media data from respective conferencing endpoints (); receives a mixing strategy (M) specifying properties of at least one outgoing bitstream (O, O, O, O, O) and requiring at least one additive media mixing step; and supplies at least one outgoing bitstream by executing, in a processor () and a memory () with a plurality of memory spaces, a run list of operations selected from a predefined collection of primitives and realizing the received mixing strategy. A pre-processor () in the server derives said run list repeatedly and dynamically while taking into consideration determined momentary activity in each incoming bitstream. In embodiments, the run list may be derived by (a) pruning of an initial run list, (b) constrained or non-constrained minimization of a cost function, or (c) automatic code generation.
