Methods and apparatus to verify and/or correct media lineup information

At least one non-transitory computer readable medium comprising instructions which, when executed, cause one or more processors to at least:

• when media presentation data representative of media output by a media device does not correspond to reference data associated with first reference media corresponding to a first station:
• identify a plurality of first signatures in a database that match a plurality of second signatures included in the media presentation data, the plurality of first signatures including at least one of first audio signatures or first video signatures, the plurality of second signatures including at least one of second audio signatures or second video signatures generated from the media output by the media device;
• and
• determine second reference media corresponding to the plurality of first signatures.

An apparatus comprising:

• memory;
• computer readable instructions;
• processor circuitry to execute the computer readable instructions to at least:
• when media presentation data representative of media output by a media device does not correspond to reference data associated with first reference media corresponding to a first station:
• identify a plurality of first signatures in a database that match a plurality of second signatures included in the media presentation data, the plurality of first signatures including at least one of first audio signatures or first video signatures, the plurality of second signatures including at least one of second audio signatures or second video signatures generated from the media output by the media device;
• and
• determine second reference media corresponding to the plurality of first signatures.
