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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detecting channel change in automatic content recognition fingerprint matching","description":"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 f","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9706261","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
