New pending patent applications are published on Thursdays by the USPTO. Both of this week's Spotlight Applications concern aspects of digital fingerprinting. Assigned to Gracenote, the first application discloses a computing system with content-characteristic-based trigger feature. Assigned to Dolby, the second application discloses techniques for acquisition, recovery, and matching of unique information from file-based media for automated file detection.
20170195752, "Computing system with content-characteristic-based trigger feature," assigned to Gracenote.
In one aspect, an example method includes (i) receiving, by a computing system, media content; (ii) generating, by the computing system, a fingerprint of a portion of the received media content; (iii) determining, by the computing system, that the received media content has a predefined characteristic; (iv) responsive to determining that the received media content has the predefined characteristic, transmitting, by the computing system, the generated fingerprint to a content identification server to identify the portion of the received media content; and (v) performing an action based on the identified portion of media content.
20170195721, "Acquisition, recovery, and matching of unique information from file-based media for automated file detection," assigned to Dolby.
A media fingerprint archive system generates and archives media fingerprints from second media content portions such as commercials. A downstream media measurement system can extract/derive query fingerprints from an incoming signal, and query the media fingerprint archive system whether any of the query fingerprints matches any archived fingerprints. If so, the media measurement system can perform media measurements on a specific secondary media content portion from which the matched query fingerprint is derived. If not, the media measurement system can analyze media characteristics of a media content portion to determine whether the media content portion is a secondary media content portion and perform media measurement if needed to. The media measurement system may send fingerprints from an identified secondary media content portion to the media fingerprint archive system for storage.
