1. A method for synchronization of a host media signal, the method comprising:

  • using one or more programmed processors to perform acts of;

    detecting peaks due to redundancy of features in a host media signal;

    wherein the redundancy is controlled via a state machine that repeats a portion of a watermark structure, and varies another portion of the watermark structure over a coordinate system of the host media signal;

    analyzing the peaks to derive estimates of geometric or temporal distortion of the host media signal;

    computing a histogram of the estimated geometric or temporal distortion parameters; and

    from the histogram, computing a geometric or temporal distortion of the host media signal.
