    摘要： This patent document details, e.g., claims and systems for watermark decoding from streaming media signals. One claim recites an apparatus comprising: electronic memory for buffering a streaming media signal; one or more electronic processors programmed for: ranking buffered portions of the media signal in terms of their ability to hide steganographic indicia; detecting steganographic indicia from relatively higher-ranked portions of the streaming media signal before attempting to detect from relatively lower-ranked portions; and carrying out an action based at least in part on detection of the steganographic indicia. Of course, other claims and disclosure are provided too.

    摘要： The disclosure details methods and systems for watermark encoding and decoding. In one implementation a method is provided to detect steganographic indicia embedded in a streaming media signal. The method includes receiving a streaming media signal; caching selected portions of the streaming media signal; detecting steganographic indicia from cached portions of streaming content; and carrying out an action based at least in part on detection of the steganographic indicia. Additional solutions, methods and implementations are detailed in the disclosure.

    摘要： The disclosure details methods and systems for watermark encoding and decoding in imaging devices, such as printers and scanners, and imaging device interfaces. Watermark encoding and decoding functions are incorporated into printer and scanner image processing pipelines. Watermark encoders and decoders perform watermark encoding and decoding, respectively, on an image as it is being transferred from one stage of a printing or scanning process to another. In particular, streaming mode watermark encoders and decoders operate on sequential portions of the image in a sequential image stream passing from one stage to another. The streaming mode encoder and decoder may be incorporated in a printer or scanner driver in a computer connected to a printer or scanner peripheral or within a printer or scanner device.
