New pending patent applications are published by the USPTO on Thursdays. Today's Spotlight Applications concern aspects of digital watermarking and digital fingerprinting. Assigned to Sony (JP), the first application discloses techniques for distributing metadata embedded in video. Assigned to Microsoft, the second application discloses techniques for communicating metadata that identifies a current speaker.
20160277793, "System for distributing metadata embedded in video," assigned to Sony (JP)
A method, non-transitory computer-readable storage medium, and reception apparatus for extracting metadata, and an information providing apparatus for providing the metadata. The method for extracting metadata includes processing, by circuitry of the reception apparatus, content that includes the metadata embedded therein. The metadata is embedded as a watermark in a first portion of a video frame of the content. The circuitry determines symbol values of the watermark from the video frame based on luminance values in pixels of the first portion of the video frame of the content to extract the metadata. At least one of the luminance values is less than 16.
20160275952, "Communicating metadata that identifies a current speaker," assigned to Microsoft.
A computer system may communicate metadata that identifies a current speaker. The computer system may receive audio data that represents speech of the current speaker, generate an audio fingerprint of the current speaker based on the audio data, and perform automated speaker recognition by comparing the audio fingerprint of the current speaker against stored audio fingerprints contained in a speaker fingerprint repository. The computer system may communicate data indicating that the current speaker is unrecognized to a client device of an observer and receive tagging information that identifies the current speaker from the client device of the observer. The computer system may store the audio fingerprint of the current speaker and metadata that identifies the current speaker in the speaker fingerprint repository and communicate the metadata that identifies the current speaker to at least one of the client device of the observer or a client device of a different observer.
