Abstract
The present invention relates generally to processing audio or video content. One claim recites an apparatus comprising: electronic memory for storing media representing audio or video content; and an electronic logic processor. The electronic processor is programmed for: embedding a protect watermark in the media, the protect watermark providing an indication that the media is protected; embedding a rights watermark in the media, the rights watermark providing an indication of user rights associated with rendering the audio or video content, in which the protect watermark is more difficult to remove from the media relative to the rights watermark; and reproducing the audio or video content after said embedding a protect watermark in the media and embedding a rights watermark in the media. Other claims and combinations are provided as well.
