Abstract
A method and apparatus for generating and adjusting a watermark in a watermarking system comprising a watermark generator and a watermark detector includes the watermark generator emitting the watermark. The watermark detector detects the watermark. The watermark detector transmits a signal to the watermark generator. The watermark generator then adjusts the generated watermark based on the signal received from the watermark detector.
