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.

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.
