Abstract
The invention relates to a device for the distributed mixing of data streams, including a main multimedia server (10) capable of receiving at least one incoming data stream (A, B, C) and of outputting at least one outgoing data stream (A′, B′, C′), and at least one secondary multimedia server (20) capable of receiving at least one incoming data stream (D, E, F) and of outputting at least one outgoing data stream (D′, E′, F′), the main multimedia server including a selection module (11) arranged so as to select a plurality of data streams (A, B, E, F) from the incoming data streams and a global mixing module (13) arranged so as to mix the selected data streams in order to obtain an aggregated stream (S), and the secondary multimedia server including a local mixing module (21) arranged so as to mix at least two incoming data streams (E, F) received by the secondary multimedia server and selected by the selection module of the main multimedia server in order to obtain an incoming intermediate stream (T) capable of being used by the global mixing module of the main multimedia server to obtain the aggregated stream. The invention also relates to a corresponding distributed mixing method…
