New pending patent applications are published in Thursdays. Today's Spotlight Applications concern aspects of digital fingerprinting. Assigned to iSpot.TV, the first application discloses techniques for modifying advertisements. Assigned to Sorenson Media, the second application discloses techniques for detecting channel change in automatic content recognition fingerprint matching.
20160366492, "Advertisement modification method and apparatus," assigned to iSpot.TV, INC.
Television transmissions are received at multiple locations across a large area. Advertisements may be identified, harvested and tagged from within in the television transmissions. The advertisements may be assigned identifiers; media plans may be determined. Advertisement representations (e.g. fingerprints) may be used to identify advertisements in television content received by the smart TVs. The smart TVs may report the fingerprints along with other identifiers or samples thereof. Television content and advertisements therein as rendered by the smart TVs may be categorized as live, timeshifted, on-demand, over-the-top, and the like. The advertisements may be categorized as occurring in national or local/regional ad slots. The data from the smart TVs may be used to determine ad impressions, gross rating points, and target rating points. View rates for advertisements may also be determined and variations of advertisement may also be prepared.
20160366474, "Detecting channel change in automatic content recognition fingerprint matching," assigned to Sorenson Media, Inc.
The disclosed system and method receives, from a media device, a query fingerprint that includes an ordered sequence of frames of content being consumed, and matches the query fingerprint with frame fingerprints by determining a distance between respective frame fingerprints and corresponding ones of the ordered sequence of frames. The matching may be performed by populating a binary tree structure with respective distances, chronologically across leaf nodes of the binary tree structure, and then noting a value of the root node. If below a maximum threshold, then there is a match. The system and method may detect a channel change at the media device by traversing a right or a left sub-tree of the binary tree structure, and locating a low value (or a zero) at the first or second nodes of the sub-tree. This channel change may be useful in targeting media to content being streamed to the media device.
