An apparatus and method for applying anti-copy protection to a raster-scanned video signal are described. A first communication station transmits a communication to a second communication station. The workpiece pad furthermore comprises an ordered array of micro-structures. In addition, the interactive content may present a message that conveys an incentive to the viewer to take some action such as actuating a button when a particular commercial is presented thereby allowing the service provider and advertisers to determine how many, and which, viewers watched a particular commercial. Accordingly, a runout track number is computed by subtracting the minimum track number from the maximum track number.
