Example apparatus disclosed herein are to compare first monitored media signatures associated with an advertisement block to a plurality of sequences of monitored media signatures associated with a first time period; determine a start boundary and an end boundary of a first advertisement in the advertisement block based on the comparison of the first monitored media signatures and the plurality of sequences of monitored media signatures, the first advertisement associated with second monitored media signatures representative of a subset of the first monitored media signatures between the start boundary and the end boundary; generate an entry in an advertisement relationship graph for the second monitored media signatures, the entry to map second monitored media signatures to the first advertisement; and credit media exposure to the first advertisement based on the second monitored media signatures in the advertisement relationship graph.

Systems and methods for adaptive adjustment of advertisement boundaries in media

An example apparatus disclosed herein includes at least one memory, instructions, and at least one processor to execute the instructions to: receive first HyperLogLog (HLL) data from a first server of a first database proprietor and second HyperLogLog (HLL) data from a second server of a second database proprietor, the first HLL data including obfuscated first user impression data and the second HLL data including obfuscated second user impression data; generate union HLL data based on the first HLL data from the first database proprietor and the second HLL data from the second database proprietor by performing a union of data sets of the obfuscated first user impression data represented in the first HLL data and the obfuscated second user impression data represented in the second HLL data; and determine a total number of deduplicated unique audience members based on the union HLL data generated by the vector analyzer.

Methods and apparatus to determine a unique audience for internet-based media

Methods, apparatus, systems and articles of manufacture are disclosed to monitor streaming media. An example apparatus includes memory, instructions in the apparatus, and processor circuitry to execute the instructions to: calibrate video data based on audio data, the video data and the audio data associated with a media stream, generate a signature representative of the media stream based on the calibrated video data, compare the signature to a signature database to identify a matching signature in the signature database; and credit media corresponding to the matching signature as being viewed.

Methods and apparatus to monitor streaming media

Methods, apparatus, systems and articles of manufacture are disclosed to generate measures of unique audiences for Internet-based media. An example apparatus disclosed herein includes at least one memory, instructions, and at least one processor. The processor to execute the instructions to: receive first HyperLogLog (HLL) data from a first server of a first database proprietor and second HyperLogLog (HLL) data from a second server of a second database proprietor, the first HLL data including obfuscated first user impression data and the second HLL data including obfuscated second user impression data; generate union HLL data based on the first HLL data from the first database proprietor and the second HLL data from the second database proprietor by performing a union of data sets of the obfuscated first user impression data represented in the first HLL data and the obfuscated second user impression data represented in the second HLL data; and determine a total number of deduplicated unique audience members based on the union HLL data generated by the vector analyzer.

Methods, apparatus, systems and articles of manufacture are disclosed to monitor streaming media. An example apparatus includes a media calibrator to calibrate video data to a calibration time-base based on audio data, the video data and audio data associated with a media stream and a signature generator to generate a signature representative of the media stream based on the calibrated video data.

Methods, apparatus, systems and articles of manufacture are disclosed to generate measures of unique audiences for Internet-based media. An example method disclosed herein includes a salt generator to generate a shared salt at a first database proprietor, a database proprietor interface to the shared salt to a second database proprietor, a Hyperloglog (HLL) generator to generate a first hash vector at the first database proprietor based on the shared salt and first user impression data associated with media, the first hash vector to obfuscate first personally identifiable information of first subscribers of the first database proprietor and an AME interface to send the first hash vector to a database containing a second hash vector, the second hash vector generated by the second database proprietor using second user impression data and the shared salt, the second hash vector to obfuscate second personally identifiable information of second subscribers of the second database proprietor, the first hash vector and the second hash vector to enable a third party to a deduplicate audience size corresponding to the first user impression data and the second user impression data.
