Abstract
A method for modulating a content signal (18) to contain an auxiliary signal, the content signal (18) having content segments, the method comprising logging detections of a test content signal (20) to create one or more log files (44); parsing the one or more log files (44) to create a profile file (46); scheduling the profile file (46) to create an encode file (48); and encoding the content signal (18) with the auxiliary signal according to the encode file (48) and a modulation method.
