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.
