Abstract
A method of detecting an embedded signal in a media signal. The method comprises receiving blocks of the media signal and computing a detection metric for the blocks. The detection metric comprises a measure of coincidence of detection parameters of different blocks. The method performs subsequent detection operations based on the measure of coincidence of the detection parameters.
