Abstract
A media object 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 and second locations. Such advantages are achieved by employing watermark data as proxies for media objects and associated applications.
