An example watermark decoding apparatus includes a component detector to identify watermark components in a media signal and detect phases of the respective ones of the watermark components in the media signal. The example apparatus also includes a phase reference determiner to identify a phase reference for the watermark components. The example apparatus also includes a phase comparator to perform comparisons of the phases of the respective ones of the watermark components with the phase reference. The example apparatus also includes a phase shift determiner to determine phase shifts associated with respective ones of the watermark components based on the comparisons. In addition, the example apparatus also includes a symbol determiner to determine a symbol based on the phase shifts."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Watermarking with phase shifting","description":"Apparatus, devices, systems, methods, and articles of manufacture are disclosed for watermarking with phase shifting.
