Abstract: System, apparatus and method for determining semantic information from audio, where incoming audio is sampled and processed to extract audio features, including temporal, spectral, harmonic and rhythmic features. The extracted audio features are compared to stored audio templates that include ranges and/or values for certain features and are tagged for specific ranges and/or values. The semantic information may be associated with audio signature data Extracted audio features that are most similar to one or more templates from the comparison are identified according to the tagged information. The tags are used to determine the semantic audio data that includes genre, instrumentation, style, acoustical dynamics, and emotive descriptor for the audio signal.

Abstract: Disclosed examples involve collecting a cookie at a client device based on media accessed via a web page at the client device, and selecting a portable device identifier at the client device. The portable device identifier corresponds to a closest one of a plurality of portable devices in wireless communication with the client device. The portable device identifier is associated with a particular person. In response to instructions embedded in the media, a hypertext transfer protocol (HTTP) request is sent to a server. The HTTP request includes the cookie, the portable device identifier, and information identifying exposure to the media.

Abstract: A computer-implemented system and method for establishing media data exposure, where a media device, such as a computer, radio, television and the like, receive media data and produces research data from it. The research data may be based on computer-based or computer network-based characteristics, ancillary codes or audio signatures. As the research data is being produced, an inductive coupling is sought for nearby portable computer devices. Once a portable computing device inductively couples to the media device, information is transferred, allowing a system to determine and/or verify that specific users were exposed to particular media data.

Abstract: Apparatus, system and method for performing an action such as accessing supplementary data and/or executing software on a device capable of receiving multimedia are disclosed. After multimedia is received, a monitoring code is detected and a signature is extracted in response thereto from an audio portion of the multimedia.

Supplementary data is accessed and/or software is executed using the detected code and/or signature.

Abstract: Apparatus, system and method for encoding and/or decoding persistent universal media identification (ID) codes embedded in audio. For encoding, a persistent identifier code is generated or received from a registry database, where the code includes data for uniquely identifying a media object. Audio code components including frequency characteristics are generated to represent symbols of the persistent identifier code and the audio code components are psychoacoustically embedded into an audio portion of the media object to include the persistent identifier code within one or more of a plurality of encoding layers. Such embedded audio may be subsequently decoded by transforming the audio data into a frequency domain and processing the transformed audio data to detect the persistent identifier code.

Abstract: A computer-implemented apparatus, system and method to determine usage of a processing device, such as a cell phone, tablet, laptop, personal computer, etc. and/or to determine media exposure on a processing device. Screenshot images from the device are received and processed to form a feature map, where image characteristics are extracted from the feature map. These characteristics are then used to determine the presence of text and consequently extract text from the screenshot image. The text is then collected and compared to a library of text that is linked to specific device uses (e.g., software application, format) or specific media (e.g., artist, song, file name). Matches are then logged and used to generate audience measurement reports.
