Abstract
The present invention relates generally to hiding a signal in video, audio and/or audio-visual content. One form of hiding is steganographic encoding. In one implementation a method includes: receiving first data representing audio-visual content, the audio-visual content comprising a video portion representing video imagery or picture elements and an audio portion; processing at least a portion of the first data to recover information steganographically encoded therein; based on at least on recovered information, obtaining details associated with the audio-visual content from a data repository; generating a report including at least the details associated with the audio-visual content; and providing the report to a client or remote location. In another implementation, a method includes: receiving first data representing audio-visual content, the audio-visual content comprising a video portion representing video imagery or picture elements and an audio portion; receiving second data conveyed along with the audio-visual content, the second data being separate from the video portion and the audio portion, processing at least a portion of the first data to recover information steganographically encoded therein, if any; and making a determination concerning the audio-visual content based at least in part on a result associated with said act processing and the second data. Other implementations and combinations are provided as well.
