Media channel identification and action with multi-match detection and disambiguation based on matching with differential reference- fingerprint feature
Publication/Patent Number: US10972786B2 Publication Date: 2021-04-06 Application Number: 15/929,180 Filing Date: 2019-12-05 Inventor: Lee, Jaehyung   Lee, Dewey Ho   Cremer, Markus   Assignee: Gracenote, Inc.   IPC: H04H60/32 Abstract: A computing system compares various reference fingerprints each representing a reference media stream broadcast on a different respective known channel, and the computing system determines that a plurality of the reference fingerprints match each other, thus defining a multi-match group of the matching reference fingerprints. In response, the computing system identifies a fingerprint feature that could define a distinction between the reference fingerprints, and the computing system resolves the multi-match based on the identified feature, thereby determining the channel carrying the media stream being rendered by the media presentation device. And the server then takes channel-specific action based on the determined channel.

Media channel identification and action with multi-match detection based on reference stream comparison
Publication/Patent Number: US10939162B2 Publication Date: 2021-03-02 Application Number: 15/929,193 Filing Date: 2019-12-19 Inventor: Seo, Chung Won   Kwon, Youngmoo   Lee, Jaehyung   Assignee: Gracenote, Inc.   IPC: H04H60/32 Abstract: A computing system will compare various reference fingerprints each representing a reference media stream broadcast on a different respective known channel, and the computing system will determine that a plurality of the reference fingerprints match each other, thus defining a multi-match group of the matching reference fingerprints. Further, the computing system will determine that a query fingerprint representing a media stream being rendered by a media presentation device matches the multi-match group, thus raising a question of which channel is carrying the media stream that is being rendered by the media presentation device. By considering one or more attributes of the query fingerprint, the server may then disambiguate and thereby determine the channel at issue, and the server may in turn take channel-specific action.
