New pending patent applications are published on Thursdays. Both of today's Spotlight Applications concern aspects of digital fingerprinting. Assigned to Google, the first application discloses techniques for broadcast audience interaction and participation. Assigned to Enswers (KR), the second application discloses techniques for providing image-based video service.
20160261917, "Systems and methods for broadcast audience interaction and participation," assigned to Google.
A broadcast audience interaction and feedback system may discover and activate a recording function of a portable device of a user to record audio and/or video of media content output by a media device in proximity to the user. The audio or video data may be used to identify the content by matching audio or video fingerprints or signatures of the data recorded by the portable device with separately generated signatures or fingerprints associated with the content. Additional entities may be automatically associated with the content via capturing of metadata or closed captioning data during the content, OCR of displayed text in the content, or detection of other such entities. In some implementations, the portable device may also capture feedback from the user, including cheering, applause, and laughter, as well as explicit questions or comments, voting choices, etc. The feedback may be identified, and queries generated or additional functions performed based on the identified feedback, the identified media content, and/or one or more entities associated with the identified media content.
20160255380, "System and method for providing image-based video service," assigned to Enswers CO LTD. (KR).
The present invention provides a system for providing image-based video service, including a cache system configured to store video information that matches image-related data; a fingerprint extraction unit configured to extract the fingerprint of an image corresponding to input image-related data; and a matching unit configured to determine video information that matches the fingerprint of the image extracted by the fingerprint extraction unit; wherein the system for providing image-based video service determines video information, matching image-related data received from a client terminal, via the cache system or the matching unit, and transmits video result information corresponding to the determined video information to the client terminal, and a method using the same.
