The invention relates to a method and device for mixing video streams in a video mixer device, by means of which a plurality of input video streams from different subscribers which are encoded with code words for macroblocks and in which the code words have interdependencies are combined into an output video stream. The input video streams are at least entropy-decoded to such a degree that the dependencies among the code words are dissolved, wherein the macroblocks are re-organized and mixed with each other, and the mixed macroblocks are entropy-encoded to obtain a new dedicated video stream.
