The commercial detection system determines whether a same match between the probe audio fingerprint and a reference audio fingerprint is observed across multiple broadcast channels. Responsive to the number of same matches exceeding a predetermined threshold, the commercial detection system determines that the media stream has commercial content. The commercial detection system may also apply a trained feature analysis model to extracted acoustic features of the audio signal. The commercial detection system determines whether the media stream has commercial content based on a confidence score assigned to the probe audio fingerprint. The commercial detection system reduces false positive detection using program guide information of the media stream."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Commercial detection based on audio fingerprinting","description":"A commercial detection system generates a probe audio fingerprint of an audio signal associated with a media stream on a broadcast channel and determines whether the media stream has commercial conten","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9832523","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.
