摘要： A method and system for adding overtly human-perceptible supplemental audio content into a media stream to help mask audio effects of an audio watermark in the media stream. A method involves receiving a media stream that defines a sequence of audio content presentable by a content presentation device, modifying the media stream to produce a modified media stream that defines the sequence of audio content, and outputting the modified media stream for presentation by the content presentation device. The modified media stream includes an audio watermark that is machine-detectable to trigger an interactive event. Further, the act of modifying the media stream involves adding into the media stream supplemental audio content coincident with the audio watermark, to help mask the audio watermark in the modified media stream during presentation of the modified media stream by the content presentation device.

摘要： Methods, apparatus, systems and articles of manufacture are disclosed to use station identification to enable confirmation of exposure to live media. Example apparatus disclosed herein include a watermark data segmenter to determine a media identifier conveyed by a watermark, a detection time determiner to determine a time at which a media meter detected the watermark from a media presentation by a media device, a reference identifier to query a library of reference signatures for a reference signature associated with the media identifier of the watermark and associated with a reference timestamp corresponding to the time at which the media meter detected the watermark, and a viewing type determiner to determine whether the media presentation is live or time-shifted based on whether a result of the query indicates the reference signature does not exist in the library of reference signatures.

摘要： Methods, apparatus, systems and articles of manufacture to update audio sensor configuration are disclosed. An example apparatus includes at least one memory, instructions in the apparatus, and processor circuitry to execute the instructions to: in response to detection of an update to audio sensor configuration, identify a plurality of potential audio sensor configurations to be used to receive audio, select respective ones of the identified potential audio sensor configurations for testing, determine signal-to-noise ratios corresponding to each of the selected ones of the potential audio sensor configurations, select the greatest signal-to-noise ratio of the signal-to-noise ratios, compare the greatest signal-to-noise ratio value and a noise ratio change threshold, and in response to the selected greatest signal-to-noise ratio value exceeding the noise ratio change threshold, update a configuration memory to cause use of the potential audio sensor configuration corresponding to the selected greatest signal-to-noise ratio.

摘要： Apparatus, systems, articles of manufacture, and methods to identify and credit media using ratios of media characteristics are disclosed herein. Example apparatus to identify media include at least one memory, instructions, and at least one processor to execute the instructions to: determine a first ratio based on a first time interval and a second time interval of a monitored media signal; determine a second ratio based on the second time interval and a third time interval of the monitored media signal; generate a first ratio signature based on the first and second ratios; and initiate transmission of the first ratio signature to a recipient that is to compare the first signature with a second ratio signature to identify the media.

摘要： Example metering apparatus and related methods are disclosed. An example apparatus disclosed herein includes a stencil and a housing having a display area. The display area has a first recessed cavity and a second recessed cavity adjacent the first recessed cavity. The first recessed cavity is offset relative to the second recessed cavity such that the second recessed cavity defines a front surface of the display area and a peripheral lip of a front side of the housing. A cover is removably coupled to the housing to enable access to the display area. The second recessed cavity of the housing is to receive the cover. The cover is received by the second recessed cavity such that an outer surface of the cover is substantially flush mounted relative to a peripheral lip of the housing, and wherein a perimeter of the cover is substantially similar to a perimeter of the peripheral lip.
