    摘要: Embodiments provide methods for modification of an encoded data stream of data packets, wherein each data packet comprises one information bit. In the data stream, the information bits of sequential data packets display time intervals from each other which differ from desired time intervals and which are adapted to the desired time intervals by insertion of an artificially encoded, first data packet into the encoded data stream in the encoded domain temporally after a second data packet, or by removal of a fourth data packet present in the encoded data stream from the encoded data stream in the encoded domain.

    摘要: 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.
