A system and method for searching based on input multimedia content elements. The method includes obtaining at least one signature for each of at least one input multimedia content element, each signature representing a concept, wherein each concept is a collection of signatures and metadata representing the concept; determining, based on the obtained signatures, at least one context of the at least one input multimedia content element; generating, based on the determined at least one context, at least one query; and searching in at least one data source using the generated at least one query.

A system and method for identifying trending content based on context. The method includes generating at least one signature for each of a plurality of multimedia content elements, wherein each signature represents a concept, wherein each concept is a collection of signatures and metadata describing the concept; correlating the concepts of the generated signatures to determine at least one context of each multimedia content element, wherein each context represents a sentiment; and identifying, based on the determined contexts, at least one trending multimedia content element, wherein the context of each trending multimedia content element meets a sentiment threshold.

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.

The present invention relates to an advertisement detection system based on fingerprints, and provides an advertisement detection systems based on fingerprints, including a content stream storage unit for storing broadcast content in real time, a section selection unit for selecting a reference section and a test section from broadcast content stored by the content stream storage unit, a fingerprint extraction unit for extracting fingerprints from the reference section and the test section selected by the section selection unit using one or more methods, a fingerprint matching unit for comparing the fingerprints from the test section and the reference section, extracted by the fingerprint extraction unit, with each other and then performing matching between the fingerprints, an advertisement section determination unit for determining advertisement segments from the test section based on results of the matching performed by the fingerprint matching.

Methods and apparatus to generate reference signatures are disclosed. An example method includes collecting a first signature for media being presented to a plurality of households; crediting the media when the first signature matches a reference signature in a reference signature database; in response to determining that the first signature does not match a reference signature in the reference signature database and the first signature does not match an unidentified signature in an unknown signature database, storing the first signature in the unknown signature database; in response to determining that a second signature does not match the reference signature in the reference signature database and the second signature matches the unidentified signature in the unknown signature database, and increasing a count associated with the unidentified signature.

Methods, apparatus, systems and articles of manufacture are disclosed for associating different watermarks detected in media. An example method disclosed herein includes determining whether a first watermark detected in a media signal is represented in a watermark data structure and associating the first watermark with a first media presentation record associated with a second watermark in response to the first watermark being associated in the watermark data structure with the second watermark. The example method further includes transmitting monitoring data including the first media presentation record to an audience measurement entity.

Embodiments are directed towards providing supplemental content to a viewer based on the viewer's environment while the viewer is viewing content. Content is provided to a content receiver for presentation to the viewer. While the viewer is viewing the content, an image of the viewer's environment is captured and analyzed to detect the context of the environment. Supplemental content is selected based on this detected context and presented to the viewer, which allows the supplemental content to be tailored to the viewer. One or more additional images of the viewer's environment are captured while the viewer is viewing the supplemental content and the context of the viewer's environment emotion while the viewer is viewing the supplemental content is detected. This subsequent context is analyzed to determine if the viewer had an expected response to the supplemental content, which can be used to determine the efficiency of the supplemental content.

Aspects of the subject disclosure may include, for example, capturing first monitoring information associated with an audience that is viewing a presentation, determining an actual audience engagement level by performing pattern recognition on the first monitoring information, comparing the actual audience engagement level with an expected audience engagement level to generate an engagement score for the presentation, and transmitting, to a device, a haptic feedback according to the engagement score during the presenting of the presentation. Other embodiments are disclosed.
