Patent ID: 7779271

Claim:
A NON-Transitory computer readable storage medium including a set of instructions stored thereon, which when executed by a digital processing system cause the digital processing system to perform a method of embedding a watermark in a media signal in the form of a bit stream, the method comprising: receiving , at a local station, auxiliary data along with the media signal from a remote location; retrieving an embedding strength parameter from the auxiliary data, said embedding strength parameter being computed at the remote location and being representative of an embedding strength with which the watermark is to be embedded in the media signal at the local station; and either embedding said watermark in the media signal at the local station with the embedding strength parameter as the embedding strength or embedding said watermark in the media signal at the local station with a fixed embedding strength as the embedding strength such that the watermark is perceptible in response to the embedding strength parameter not being found or being corrupt.
