US 2025/0149059 A1 · METHODS AND APPARATUS TO PERFORM SIGNATURE MATCHING USING NOISE CANCELLATION MODELS TO ACHIEVE CONSENSUS

Abstract

Examples are disclosed to perform signature matching using noise cancellation models to achieve consensus. Example apparatus disclosed herein include a signature matcher to compare a first stream of monitored media signatures to streams of reference signatures representative of corresponding reference media to determine a first signature match, and compare a second stream of monitored media signatures to the streams of reference signatures to determine a second signature match; a match selector to use at least one the first signature match or the second signature match to identify a first one of the reference media corresponding to the monitored media data; and a creditor interface to output identification data for the first one of the reference media identified with the at least one the first signature match or the second signature match, the identification data to be used to credit a media exposure corresponding to the monitored media.

Dependent claims

A media meter device comprising:

at least one microphone;
a processor;
memory having stored thereon computer readable instructions that, when executed by the processor, cause the media meter device to perform a set of operations including:
collecting raw ambient audio data using the at least one microphone;
processing the raw ambient audio data with a noise reduction model to thereby generate modified audio data;
generating a stream of modified audio signatures based on the modified audio data, wherein each of the modified audio signatures is generated from a modified version of a corresponding portion of the raw ambient audio;
determining, for respective ones of the modified audio signatures, timestamp values corresponding to times at which respective corresponding portions of the raw ambient audio data were collected using the at least one microphone;
associating the determined timestamp values with the respective ones of the modified audio signatures;
and
transmitting the stream of modified audio signatures with the associated determined timestamp values to a matching server for comparison with reference audio signatures.

collecting raw ambient audio data using at least one microphone;
processing the raw ambient audio data with a noise reduction model to thereby generate modified audio data;
generating a stream of modified audio signatures based on the modified audio data, wherein each of the modified audio signatures is generated from a modified version of a corresponding portion of the raw ambient audio;
determining, for respective ones of the modified audio signatures, timestamp values corresponding to times at which respective corresponding portions of the raw ambient audio data were collected using the at least one microphone;
associating the determined timestamp values with the respective ones of the modified audio signatures;
and
transmitting the stream of modified audio signatures with the associated determined timestamp values to a matching server for comparison with reference audio signatures.
