1. A method of managing media content, comprising:
- providing a media signal in which perceptible portions are intentionally degraded in perceptual quality;
in response to receiving authorization, transforming the media signal into a higher quality media signal in which the intentional degradation is corrected, including embedding an identifying code into the higher quality media signal, wherein the intentionally degraded portions are formed by adding a perceptible noise signal to the media content.

Abstract
A method of managing media content provides a media signal in which perceptible portions are intentionally degraded in perceptual quality. In response to receiving authorization, the method transforms the media signal into a higher quality media signal in which the intentional degradation is corrected. In addition, the media content is transformed by embedding an identifying code into the higher quality media signal. Media signal processing hardware includes a receiver of the media signal and activation hardware that transforms the media signal content in response to authorization, including embedding the identifying code.
