Generation of mixed media streams

摘要

To achieve coordination during generation of a plurality of mixed media streams, there is suggested a method of generating a mixed media stream ( 62 - 64 ) from input media streams ( 40 - 50 ) having payload data elements and related identifiers. The method comprises the step (S 12 ) of aligning the input media streams ( 40 - 50 ) according to a pre-specified relation between identifiers in different input media streams ( 40 - 50 ) before generating the mixed media stream.
