ABSTRACT:
In order to decode a received digital signal which has been watermarked with a known watermark, at least part of the digital signal is decoded by using a parametrisable iterative decoder, the watermark is extracted from the decoded signal, the extracted watermark is compared with the known watermark, and at least one parameter of the decoder is modified if necessary, according to the result of the comparison.
