New patents are issued by the USPTO on Tuesdays. Today's Spotlight Patents concern aspects of digital fingerprinting and digital watermarking. Assigned to Facebook, the first patent addresses techniques for detecting commercials based on audio fingerprinting. Assigned to Digimarc, the second patent addresses media processing methods and arrangements using digital watermarking. #Digimarc #Facebook
9,258,604, "Commercial detection based on audio fingerprinting," assigned to Facebook.
A commercial detection system generates a probe audio fingerprint of an audio signal associated with a media stream on a broadcast channel and determines whether the media stream has commercial content based on analysis of the probe audio fingerprint. The commercial detection system determines whether a same match between the probe audio fingerprint and a reference audio fingerprint is observed across multiple broadcast channels. Responsive to the number of same matches exceeding a predetermined threshold, the commercial detection system determines that the media stream has commercial content. The commercial detection system may also apply a trained feature analysis model to extracted acoustic features of the audio signal. The commercial detection system determines whether the media stream has commercial content based on a confidence score assigned to the probe audio fingerprint. The commercial detection system reduces false positive detection using program guide information of the media stream.

The disclosure relates, e.g., to media processing methods and arrangements. One method includes: obtaining first optical data in a first user's cell phone, the first optical data corresponding to a first face of a product's packaging, the product also including a second face of the packaging, the first face comprises first digital watermarking conveying first data and the second face comprises second digital watermarking convey second data; analyzing the first optical data to obtain the first data therefrom; responsive to providing the first data to a remotely located computer resource, the first user's cell phone receiving a first response; obtaining second optical data in a first user's cell phone, the second optical data corresponding the second face of the packaging; analyzing the second optical data to obtain the second data therefrom; responsive to providing the second data to a remotely located computer resource, the first user's cell phone receiving a second response, the second response being different from the first service; and storing in the cell phone an association between: i) the first data and the first response, and ii) the second data and the second response. Of course other methods, combinations and systems are disclosed as well.
