Abstract
Methods, apparatus, systems and articles of manufacture (e.g., physical storage media) to implement power efficient detection of watermarks in media signals are disclosed. Example watermark detection methods disclosed herein include operating a watermark detector in a first operating mode to detect a first watermark in a media signal. Disclosed example watermark detection methods also include, in response to the first watermark being verified, operating the watermark detector in a second operating mode in which the watermark detector cycles between sleep intervals and active intervals to detect a second watermark at a second location in the media signal relative to a first location of the first watermark in the media signal.
