Abstract
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.

10. A method comprising acts of:
-
receiving streaming content representing a media signal; selecting certain portions of the streaming content; caching selected portions of the streaming content in electronic memory; detecting steganographic indicia from cached portions of streaming content, in which steganographic indicia detection is performed in a device driver executing in a computer as the media signal is passed from an application program to a device, and in which the device driver includes 16 bit code, the steganographic indicia detection is implemented in 32 bit code, and the steganographic indicia detection is invoked from the 16 bit code through an application programming interface of the 32 bit code; and carrying out an action based at least in part on detection of the steganographic indicia. - View Dependent Claims (11, 23)
