Method and system for remotely controlling consumer electronic devices
Publication/Patent Number: US10904589B2 Publication Date: 2021-01-26 Application Number: 16/568,445 Filing Date: 2019-09-12 Inventor: Gordon, Donald F.   Assignee: Gracenote inc   IPC: H04N21/234 Abstract: A media system replaces content in a first sequence of media content. The media system presents the first sequence of media content to an end-user and generates a fingerprint of the sequence of media content. The fingerprint is for comparison with a plurality of reference fingerprints so as to identify the first sequence of media content and determine a reference position within the first sequence of media content. The media system sends a request for a replacement sequence of content to a content replacement system, and receives replacement media content selected based on the identified first sequence of media content. The media system presents the replacement media content to the end-user instead of the first sequence of media content. Presenting the replacement media content begins at a position in the first sequence of media content that is determined based on the reference position.

Method and System for Use of Earlier and/or Later Single-Match as Basis to Disambiguate Channel Multi-Match with Non-Matching Programs
Publication/Patent Number: US2021021893A1 Publication Date: 2021-01-21 Application Number: 16/586,552 Filing Date: 2019-09-27 Inventor: Sunku, Raghavendra   Lee, Jaehyung   Debelair, Virginie   Dunker, Peter   Assignee: Gracenote inc   IPC: H04N21/442 Abstract: A computing system detects a channel multi-match with non-matching programs, based on fingerprint-based ACR analysis of digital fingerprint data representing a channel rendered by a content presentation device. The system then responsively performs disambiguation based at least in part on detecting an earlier single-channel match and/or a later single-channel match, the disambiguation establishing that the channel rendered by the content presentation device is the single known channel. And based on the disambiguation, the system then uses the single known channel as a basis for carrying out of at least one channel-specific operation, such as recording audience-measurement data and/or invoking dynamic content modification.

Dynamic Video Overlays
Publication/Patent Number: US2021037283A1 Publication Date: 2021-02-04 Application Number: 16/928,683 Filing Date: 2020-07-14 Inventor: Cremer, Marcus K.   Dunker, Peter   Sherf, Steven D.   Pearce, David Henry   Li, Sherman Ling Fung   Harron, Wilson   Dimitriou, Konstantinos Antonios   Lee, Dewey Ho   Assignee: Gracenote inc   IPC: H04N21/44 Abstract: A client device accesses a video input stream from an intermediate device for display. The client device analyzes the video input stream to determine that the video input stream matches a template corresponding to a screen portion. Based on the video input stream matching the template, a video output stream is generated and caused to be presented on a display. In some example embodiments, the analysis is performed while the client device is replacing video content received from a content source via the intermediate device. For example, commercials transmitted from a national content provider to a smart TV via a set-top box may be replaced with targeted commercials. During the replacement, menus generated by the set-top box may be detected and the replacement video altered by the smart TV to include the menus.

Digital Video Fingerprinting Using Motion Segmentation
Publication/Patent Number: US2021020171A1 Publication Date: 2021-01-21 Application Number: 16/916,179 Filing Date: 2020-06-30 Inventor: Pereira, Jose Pio   Stojancic, Mihailo M.   Assignee: Gracenote inc   IPC: G10L15/20 Abstract: Methods of processing video are presented to generate signatures for motion segmented regions over two or more frames. Two frames are differenced using an adaptive threshold to generate a two-frame difference image. The adaptive threshold is based on a motion histogram analysis which may vary according to motion history data. Also, a count of pixels is determined in image regions of the motion adapted two-frame difference image which identifies when the count is not within a threshold range to modify the motion adaptive threshold. A motion history image is created from the two-frame difference image. The motion history image is segmented to generate one or more motion segmented regions and a descriptor and a signature are generated for a selected motion segmented region.

Publication/Patent Number: US10924816B2 Publication Date: 2021-02-16 Application Number: 16/734,283 Filing Date: 2020-01-03 Inventor: Nagorski, Igor Alexandrovich   Nesvadba, Jan Alexis Daniel   Aarts, Ronaldus Maria   Assignee: Gracenote inc   IPC: H04N21/81 Abstract: A main stream contains successive content elements of video and/or audio information that encode video and/or audio information at a first data rate. A computation circuit (144) computes main fingerprints from the successive content elements. A reference stream is received having a second data rate lower than the first data rate. The reference stream defines a sequence of the reference fingerprints. A comparator unit (144) compares the main fingerprints with the reference fingerprints. The main stream is monitored for the presence of inserted content elements between original content elements, where the original content elements have main fingerprints that match successive reference fingerprints and the inserted content elements have main fingerprints that do not match reference fingerprints. Rendering of inserted content elements to be skipped. In an embodiment when more than one content element matches only one is rendered. In another embodiment matching is used to control zapping to or from the main stream. In another embodiment matching is used to control linking of separately received mark-up information such as subtitles to points in the main stream.

Publication/Patent Number: US10977307B2 Publication Date: 2021-04-13 Application Number: 16/240,859 Filing Date: 2019-01-07 Inventor: Pereira, Jose Pio   Stojancic, Mihailo M.   Merchant, Shashank   Assignee: Gracenote inc   IPC: G06F16/00 Abstract: A multi-dimensional database and indexes and operations on the multi-dimensional database are described which include video search applications or other similar sequence or structure searches. Traversal indexes utilize highly discriminative information about images and video sequences or about object shapes. Global and local signatures around keypoints are used for compact and robust retrieval and discriminative information content of images or video sequences of interest. For other objects or structures relevant signature of pattern or structure are used for traversal indexes. Traversal indexes are stored in leaf nodes along with distance measures and occurrence of similar images in the database. During a sequence query, correlation scores are calculated for single frame, for frame sequence, and video clips, or for other objects or structures.
