Abstract

In one example, a method performed by an audience measurement computing system is described. The method includes determining a source identifier that identifies a media source from which media presented by a media presentation device at a media presentation environment is received. The method also includes using meter hash keys and the source identifier as a basis to select, from stored reference hash keys representing signatures of previously-identified media, a set of reference hash keys that match the meter hash keys and correspond to the source identifier, each reference hash key associated with a corresponding media identifier, where the meter hash keys are generated based on meter signatures representing the media. The method also includes identifying the media based on the set of reference hash keys. The method also includes generating exposure data that credits exposure of an audience member at the media presentation environment to the identified media.

First claim

What is claimed is:

1 . A non-transitory computer-readable storage medium, having stored thereon program instructions that, upon execution by a processor of an audience measurement computing system, cause performance of operations comprising:
determining a source identifier that identifies a media source from which media presented by a media presentation device at a media presentation environment is received; using meter hash keys and the source identifier as a basis to select, from stored reference hash keys generated based on reference signatures representing previously-identified media, a set of reference hash keys that match the meter hash keys and correspond to the source identifier, each reference hash key associated with a corresponding media identifier, wherein the meter hash keys are generated based on meter signatures representing the media; identifying the media by matching at least a subset of the meter signatures to at least a subset of reference signatures from which the set of reference hash keys selected using the meter hash keys a ad the source identifier were generated; and generating exposure data that credits exposure of an audience member at the media presentation environment to the identified media.

2 . The non-transitory computer-readable storage medium of claim 1 , wherein determining the source identifier comprises:
receiving, from a meter computing system at the media presentation environment, one or more of an Internet Protocol (IP) address or a domain name associated with the media source; and determining the source identifier based on data that maps IP addresses and domain names to corresponding media sources.

3 . The non-transitory computer-readable storage medium of claim 2 , the operations further comprising:
receiving the meter signatures from the meter computing system; and generating the meter bash keys based on the meter signatures.

4 . The non-transitory computer-readable storage medium of claim 3 , wherein:
the meter computing system comprises a first meter device and a second meter device, the first meter device is configured to generate the meter signatures and transmit the meter signatures to the audience measurement computing system, and the second meter device is configured to monitor network traffic to the media presentation device and transmit one or more of the IP address of the domain name to the audience measurement computing system.

5 . The non-transitory computer-readable storage medium of claim 1 , wherein determining the source identifier comprises determining the source identifier based on predetermined audience data that maps one or more of a media presentation environment identifier of the media presentation environment or an audience member identifier of the audience member to one or more source identifiers.

6 . The non-transitory computer-readable storage medium of claim 1 , wherein the media source comprises a streaming media source.

7 . The non-transitory computer-readable storage medium of claim 1 , wherein:
using the meter hash keys and the source identifier as a basis to select the set of reference hash keys comprises:
for each of the meter hash keys, querying a database for one or more reference hash keys that match the meter hash key and correspond to the source identifier; and
receiving the set of reference hash keys in response to the querying, and
the database comprises data that maps reference hash keys to respective source identifiers.

8 . The non-transitory computer-readable storage medium of claim 1 , wherein using the meter hash keys and the source identifier as a basis to select the set of reference hash keys comprises:
for each of the meter hash keys, querying a database for one or more reference hash keys that match the meter hash key; and for each of the one or more reference hash keys:
determining that the reference hash key corresponds to the source identifier, and
based on the determination that the reference hash key corresponds to the source identifier, storing the reference hash key in a data structure associated with a particular one of the media identifiers.

9 . The non-transitory computer-readable storage medium of claim 1 , wherein identifying the media based on the set of reference hash keys comprises:
selecting, from the set of reference hash keys, a subset of reference hash keys that satisfy a set of validation conditions; and identifying the media based on the subset of reference hash keys.

10 . A method performed by an audience measurement computing system, the audience measurement computing system comprising a processor, the method comprising:
determining a source identifier that identifies a media source from which media presented by a media presentation device at a media presentation environment is received; using meter hash keys and the source identifier as a basis to select, from stored reference hash keys generated based on reference signatures representing previously-identified media, a set of reference hash keys that match the meter hash keys and correspond to the source identifier, each reference hash key associated with a corresponding media identifier, wherein the meter hash keys are generated based on meter signatures representing the media; identifying the media by matching es subset of the meter signatures to at least a subset of reference signatures from which the set of reference hash keys selected using the meter hash keys and the source identifies were generated; and generating exposure data that credits exposure of an audience member at the media presentation environment to the identified media.

11 . The method of claim 10 , wherein determining the source identifier comprises:
receiving, from a meter computing system at the media presentation environment, one or more of an Internet Protocol (IP) address or a domain name associated with the media source; and determining the source identifier based on data that maps IP addresses and domain names to corresponding media sources.

12 . The method of claim 11 , further comprising:
receiving the meter signatures from the meter computing system; and generating the meter hash keys based on the meter signatures.

13 . The method of claim 12 , wherein:
the meter computing system comprises a first meter device and a second meter device, the first meter device is configured to generate the meter signatures and transmit the meter signatures to the audience measurement computing system, and the second meter device is configured to monitor network traffic to the media presentation device and transmit one or more of the IP address of the domain name to the audience measurement computing system.

14 . The method of claim 10 , wherein determining the source identifier comprises determining the source identifier based on predetermined audience data that maps one or more of a media presentation environment identifier of the media presentation environment or an audience member identifier of the audience member to one or more source identifiers.

15 . The method of claim 10 , wherein:
using the meter hash keys and the source identifier as a basis to select the set of reference hash keys comprises:
for each of the meter bash keys, querying a database for one or more reference hash keys that match the meter hash key and correspond to the source identifier; and
receiving the set of reference bash keys in response to the querying, and the database comprises data that maps reference hash keys to respective source identifiers.

16 . The method of claim 10 , wherein using the meter hash k
