New patents are issued by the PTO on Tuesdays. Both of today's Spotlight Patents concern aspects of audio fingerprinting. Assigned to Sony, the first patent addresses techniques for media fingerprinting for social networking. Assigned to Google, the second of today's patents addresses techniques for generating a sequence of audio fingerprints at a set top box.
9,113,217, "Media fingerprinting for social networking," assigned to Sony Computer Entertainment (JP).
Audio fingerprinting and other media matching technologies can be used to identify media, such as movies, television shows, and radio broadcasts. A user device can record image, audio, and/or video information and upload information to a matching service that is able to use matching technology to identify the media and provide supplemental content or information to the user. The user then can share this information with other users, such as by uploading to a social networking site or passing the information to peers on a peer network as part of a container. Users can have the ability to add tagged content, provide comments and ratings, and otherwise interact based at least in part upon the tagged media content.
9,113,203, "Generating a sequence of audio fingerprints at a set top box," assigned to Google.
A computer-implemented method for generating audio fingerprints at a set top box that is communicatively coupled to a television and reporting the audio fingerprints from the set top box to a remote server is disclosed. After receiving a video signal and an audio signal associated with the video signal from a TV content provider, both of which correspond to a TV program being played on the television, the set top box generates a plurality of audio fingerprints from the audio signal, at least one of which corresponds to a predefined video scene transition detected in the video signal. The set top box then sends the plurality of audio fingerprints to the remote server for determining TV program information associated with the TV program.
