Methods and apparatus to reduce false positive signature matches due to similar media segments in different reference media assets

An apparatus comprising:

• at least one memory;
• instructions in the apparatus;
• and
• processor circuitry to execute the instructions to at least:
• identify matched reference media assets associated with matches between a sequence of monitored media signature and ones of a plurality of sequences of reference media signatures, the sequence of monitored media signatures associated with monitored media, the ones of the sequences of reference media signatures associated with respective reference media assets;
• and
• classify one or more of the matched reference media assets as false positive matches based at least in part on a count of different ones of the reference media assets.

An apparatus comprising:

• at least one memory;
• and
• processor circuitry including one or more of:
• at least one of a central processing unit, a graphic processing unit or a digital signal processor, the at least one of the central processing unit, the graphic processing unit or the digital signal processor having control circuitry to control data movement within the processor circuitry, arithmetic and logic circuitry to perform one or more first operations corresponding to instructions, and one or more registers to store a result of the one or more first operations, the instructions in the apparatus;
• a Field Programmable Gate Array (FPGA), the FPGA including logic gate circuitry, a plurality of configurable interconnections, and storage circuitry, the logic gate circuitry and interconnections to perform one or more second operations, the storage circuitry to store a result of the one or more second operations;
• or
• Application Specific Integrate Circuitry including logic gate circuitry to perform one or more third operations;
• the processor circuitry to perform at least one of the first operations, the second operations or the third operations to:
• identify matched reference media assets associated with matches between a sequence of monitored media signature and ones of a library of sequences of reference media signatures, the sequence of monitored media signatures associated with monitored media, the ones of the sequences of reference media signatures associated with respective reference media assets;
• and
• associate one or more of the matched reference media assets with false positive matches based at least in part on a number of different ones of the reference media assets.
