Media Channel Identification and Action with Multi-Match Detection and Disambiguation Based on Matching with Differential Reference-Fingerprint Feature
|
Publication/Patent Number: US2018270529A1 | Publication Date: 2018-09-20 | Application Number: 15/982,437 | Filing Date: 2018-05-17 | Inventor： Lee, Jaehyung Lee, Dewey Ho Cremer, Markus | Assignee: Gracenote, Inc. | IPC: H04N21/44 | 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 with Video Multi-Match Detection and Disambiguation Based on Audio Fingerprint
|
Publication/Patent Number: US2018109841A1 | Publication Date: 2018-04-19 | Application Number: 15/842,189 | Filing Date: 2017-12-14 | Inventor： Lee, Jaehyung Kwon, Youngmoo Seo, Chung Won | Assignee: Gracenote, Inc. | IPC: H04N21/44 | 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. | |||

Method And Device for Judging Dangerous Situation of Walking Assistant Apparatus
|
Publication/Patent Number: KR20180107015A | Publication Date: 2018-10-01 | Application Number: 20180032940 | Filing Date: 2018-03-21 | Inventor： Lee, Seongil Kim, Sang Min Lee, Jaehyung | Assignee: RESEARCH & BUSINESS FOUNDATION SUNGKYUNKWAN UNIVERSITY | IPC: A61H3/04 | Abstract: Disclosed is a method for determining and controlling dangerous situation in a walking aid device. The method determines whether something dangerous has happened to a user based on at least one of a distance between the user and a walking aid device controller, movement related information related to the movement of the walking aid device, area of a modified triangle calculated by using the movement related information of the walking aid device to a basic triangle, and a vertex coordinate of the modified triangle. If a dangerous situation is determined to be taken place, the speed of the walking aid device is controlled. | |||

Media channel identification with multi-match detection and disambiguation based on single-match
|
Publication/Patent Number: US10063918B2 | Publication Date: 2018-08-28 | Application Number: 15/222,405 | Filing Date: 2016-07-28 | 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. | |||

Method and System for Detecting and Responding to Changing of Media Channel

Publication/Patent Number: US2017251247A1 | Publication Date: 2017-08-31 | Application Number: 15/443,615 | Filing Date: 2017-02-27 | Inventor： Lee, Jaehyung Lee, Dewey Ho | Assignee: Gracenote, Inc. | IPC: H04N21/44 | 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. | |||
