<p>The present invention relates to a method, device and computer program product for embedding additional data in a media signal as well as a media signal processing device having such a device for embedding additional data. In the method a media signal divided into frames having blocks of a number of signal sample values is obtained, the variance (sigma<2>) of at least one block of samples of a frame is determined, (step 34), and used for the embedding of additional data (w(i,j)) in said block, (step 36, 48).</p> |
