This patent application is generally related to watermarking and steganography. One claim recites a method of transmarking a media signal previously embedded with a first digital watermark using a first digital watermark embedding method. The method includes: utilizing a programmed electronic processor, detecting the first digital watermark in the media signal; converting the media signal to a different format; utilizing a programmed electronic processor, embedding detected message information from the first digital watermark into a second digital watermark in the converted media signal such that the second digital watermark is adapted to robustness or perceptibility parameters associated with the new format. Of course, other combinations and claims are provided as well.
