Abstract (en)
[origin: WO2011137919A1] The invention relates to a method for modifying a coded data stream comprising data packets (P1, P2, P3, P4, P5), of which each data packet (P1, P2, P3, P4, P5) comprises a piece of information (B1, B2, B3, B4, B5). In the data flow, the pieces (B1, B2) of information of consecutive data packets (P1, P2, P3, P4, P5) have time intervals (d1, d3) between each other, which deviate from target time intervals (d1) and which are set to the target time intervals (d1) by inserting an artificially coded first data packet (P2') into the coded data flow in the coded domain after a second data packet or by removing a fourth data packet (P4) present in the coded data flow from the coded data flow in the coded domain.
