<p>A media object (70) sensed at one location is delivered at a second remote location, or an application associated with the object is made available at the second location. In some embodiments, the delivered object is of a higher quality than the sensed object. In other embodiments, larger objects requiring higher bandwidth for effective transmission are delivered notwithstanding low bandwidth bottlenecks between the first (12) and second (14) locations. Such advantages are achieved by employing watermark data as proxies for media objects and associated applications. In some arrangements, the first and second locations are the same, e.g., a photocopier (50) scans a paper document, finds a watermark in a photo on the paper document, obtains from a networked resource a pristine version of the photo, and substitutes the pristine photo for the scanned photo in the photocopied output.</p> |
