The invention concerns a method and devices (1, 2) for the detection of errors, in particular transmission errors, in data streams and/or data packets. In order to better detect systematic errors in particular, the error detection function (1) according to the invention is variable. The detection function is varied on the basis of the time and/or the data themselves, for example by assigning an individual variation value to each index (packet index), thus effectively varying the data (D) on the basis of this value. The invention is particularly suitable for application to compressed data streams. <IMAGE> |
