Abstract
A method and apparatus is provided for generating or providing any of various types of modifications purposely made to generally known signals, waveforms, conditions, functions, etc. The modifications are sensed, read, detected or interpreted to provide a content control command indicative of the difference between the original signal, waveform, condition, functions, etc., and the modified signal, waveform, condition, function, etc. The content control command may be used to provide content control for a content control system, which in turn may provide control of a selected compliant device.
