MEDIA CHANNEL IDENTIFICATION AND ACTION WITH MULTI-MATCH DETECTION BASED ON REFERENCE STREAM COMPARISON
|
Publication/Patent Number: EP3780630A1 | Publication Date: 2021-02-17 | Application Number: 20197250.2 | Filing Date: 2017-02-28 | Inventor： Seo, Chung Won Kwon, Youngmoo Lee, Jaehyung | Assignee: Gracenote Inc. | IPC: H04N21/236 | 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. | |||

Media Channel Identification with Multi-Match Detection and Disambiguation Based on Time of Broadcast
|
Publication/Patent Number: US2021037285A1 | Publication Date: 2021-02-04 | Application Number: 16/949,183 | Filing Date: 2020-10-19 | Inventor： Seo, Chung Won Kwon, Youngmoo Lee, Jaehyung | Assignee: Gracenote, Inc. | IPC: H04N21/44 | Abstract: Disclosed herein are methods and systems to help disambiguate channel identification in a scenario where fingerprint data of media content being rendered by a media presentation device matches multiple reference fingerprints corresponding respectively with multiple different channels. Upon detecting such a multi-match, a server or other entity will perform disambiguation based at least in part on a comparison of time of broadcast of the media content being rendered by the media presentation device with time of broadcast of the media content represented by the reference fingerprints. The server or other entity will thereby determine the channel on which the media content being rendered by the media presentation device is arriving, so as to facilitate taking channel-specific action. | |||

Media channel identification with multi-match detection and disambiguation based on single-match

Publication/Patent Number: US10567836B2 | Publication Date: 2020-02-18 | Application Number: 16/276,061 | Filing Date: 2019-02-14 | Inventor： Lee, Jaehyung Seo, Chung Won Kwon, Youngmoo | Assignee: Gracenote, Inc. | IPC: H04H60/32 | Abstract: Disclosed herein are methods and systems to help disambiguate channel identification in a scenario where fingerprint data of media content matches multiple reference fingerprints corresponding respectively with multiple different channels. Upon detecting such a multi-match, a server or other entity will perform disambiguation based on a determination that a segment of the fingerprint data matches a reference fingerprint corresponding with just a single channel, such as a reference fingerprint representing commercial or news programming content specific to just the single channel. The server or other entity will thereby determine the channel on which the media content being rendered by the media presentation device is arriving, so as to facilitate taking channel-specific action. | |||

MEDIA CHANNEL IDENTIFICATION WITH VIDEO MULTI-MATCH DETECTION AND DISAMBIGUATION BASED ON AUDIO FINGERPRINT

Publication/Patent Number: US2020221173A1 | Publication Date: 2020-07-09 | Application Number: 16/819,657 | Filing Date: 2020-03-16 | Inventor： Seo, Chung Won Kwon, Youngmoo Lee, Jaehyung | Assignee: Gracenote, Inc. | IPC: H04N21/442 | Abstract: Disclosed are methods and systems to help disambiguate channel identification in a scenario where a video fingerprint of media content matches multiple reference video fingerprints corresponding respectively with multiple different channels. Given such a multi-match situation, an entity could disambiguate based on an audio component of the media content, such as by further determining that an audio fingerprint of the media content at issue matches an audio fingerprint of just one of the multiple channels, thereby establishing that that is the channel on which the media content being rendered by the media presentation device is arriving. | |||
