Methods and apparatus to facilitate meter to meter matching for media identification

A non-transitory computer readable medium comprising computer readable instructions that, when executed, cause at least processor to at least:

• access a matched group of candidate signature segments, the candidate signature segments from a plurality of meters, respective ones of the meters to monitor respective media presentations by corresponding ones of a plurality of media devices;
• compare signature timestamps associated with signature values of a first one of the group of candidate signature segments to respective network timestamps associated with corresponding uniform resource locators (URLs) accessed by a first one of the plurality of media devices;
• and
• in response to a determination that at least one of the signature timestamps of the first one of the group of candidate signature segments matched a first network timestamp associated with a first one of the URLs, credit ones of the group of candidate signature segments to respective presentations, by the corresponding ones of the plurality of media devices, of first media associated with first first one of the URLs.

A method comprising:

• accessing a matched group of candidate signature segments, the candidate signature segments obtained from a plurality of meters, respective ones of the meters to monitor respective media presentations by corresponding ones of a plurality of media devices, ones of the group of candidate signature segments not matching reference signatures included in a reference signature database;
• comparing, by executing an instruction with at least one processor, signature timestamps associated with signature values of a first one of the group of candidate signature segments to respective network timestamps associated with corresponding uniform resource locators (URLs) accessed by a first one of the plurality of media devices;
• and
• in response to determining that at least one of the signature timestamps of the first one of the group of candidate signature segments matched a first network timestamp associated with a first one of the URLs, crediting, by executing an instruction with the at least one processor, the ones of the group of candidate signature segments with respective presentations, by the corresponding ones of the plurality of media devices, of first media associated with the first one of the URLs.
