Abstract

A method of detecting a payload embedded using watermarking in a content stream, the payload being different in a first and a second segment of the content stream, a payload in the second segment having a predetermined relationship with a payload in the first segment, is described. The method selects a point in the content stream where the first segment is likely to end and the second segment to begin, samples the stream to obtain a first set of samples that is before the chosen point and a second set of samples that is after the chosen point, and detects the payload on a combination of the first set and a transformation of the second set, where the transformation is based on the assumption that the second set is from the second segment and exploits the relationship that exists between the payloads in the first and second segments.
