New pending patent applications are published on Thursdays by the USPTO. Today's Spotlight Applications concern aspects of digital fingerprinting. Assigned to Gracenote, the first application discloses techniques for presenting additional content at a media system. Assigned to Cohesity, the second application discloses techniques for deduplicating chunks of data across multiple clusters.
20180302673, "Method and system for presenting additional content at a media system," assigned to Gracenote.
A media system, receives a received sequence of media content, for presentation at the media system and generates a comparison fingerprint of the received sequence of media content. The comparison fingerprint is for comparison with a plurality of reference fingerprints so as to identify the received sequence of media content. The media system sends a request for identification of additional content to a server system. The request is based at least in part on the comparison fingerprint. The media system receives a response to the request, including information enabling additional content to be selected for display at the media system based at least in part on the identification of the received sequence of media content, and presents a displayed sequence of media content that includes at least a portion of the received sequence of media content and at least a portion of the additional content.
20180307701, "Global deduplication," assigned to Cohesity, Inc.
Embodiments presented herein describe techniques for deduplicating chunks of data across multiple clusters. A process executing in a storage system identifies one or more chunks in an incoming stream of data. For each chunk, a first fingerprint corresponding to the chunk is generated. The process determines whether the first fingerprint matches a second fingerprint listed in a corresponding entry in a deduplication map. Each entry of the deduplication map corresponds to a chunk stored in a location in one of the storage clusters. Upon determining that the first fingerprint matches the second fingerprint, the process writes, to a local persistent storage, a pointer referencing the location in that storage cluster.
