US2021021893A1
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.

US2021037285A1
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: EP3424219B1 Publication Date: 2021-01-20 Application Number: 17760606.8 Filing Date: 2017-02-28 Inventor: Lee, Jaehyung   Seo, Chung Won   Kwon, Youngmoo   Assignee: Gracenote, Inc.   IPC: H04N21/234

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.

US2021021884A1
Method and System for Use of Network Affiliation as Basis to Determine Channel Rendered by Content Presentation Device
Publication/Patent Number: US2021021884A1 Publication Date: 2021-01-21 Application Number: 16/586,542 Filing Date: 2019-09-27 Inventor: Sunku, Raghavendra   Lee, Jaehyung   Debelair, Virginie   Dunker, Peter   Assignee: Gracenote, Inc.   IPC: H04N21/234 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 determines a channel rendered by the device through a process including (a) determining that channels of the multi-match group are all affiliate channels of the same network as each other and (b) determining, as the channel, which affiliate channel of that network serves a location of the content presentation device. The system then uses the determined 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.

US2020149290A1
Method and System for Detecting and Responding to Changing of Media Channel
Publication/Patent Number: US2020149290A1 Publication Date: 2020-05-14 Application Number: 15/929,179 Filing Date: 2019-12-05 Inventor: Lee, Jaehyung   Lee, Dewey Ho   Assignee: Gracenote, Inc.   IPC: E04F15/02 Abstract: A computing system receives from a media presentation device a query fingerprint stream representing media content being presented by the media presentation device, where the query fingerprint stream has been determined to represent a first channel. The computing system then detects that a threshold mismatch exists between the received query fingerprint stream and a reference fingerprint stream representing the first channel, thus indicating a likelihood that the media presentation device has transitioned from presenting the first channel to presenting a second channel. Responsive to detecting the threshold mismatch, the system thus discontinues channel-specific action with respect to the first channel. For instance, the system could discontinue superimposing of first-channel-specific content on the presented media content and perhaps start superimposing of second-channel-specific content instead.
