Abstract

Methods and apparatus to create a media measurement reference database from a plurality of distributed sources are described. An example method of developing a reference database associated with media content includes receiving first identifying data associated with media content from a meter on a first information presentation device, the media content being locally accessible at the first information presentation device; determining whether the reference database includes reference data associated with the first identifying data; when the reference database lacks the reference data associated with the first identifying data, sending a message to the meter requesting first reference data for the media content; and receiving the first reference data associated with the first identifying data.

Claims

1. A method of developing a reference database to identify media content, comprising:

locating first local media content on a first information presentation device;

extracting first identifying data associated with the first local media content;

querying a central facility with the first identifying data; and

in response to an indication from the central facility that the reference database lacks validated reference data associated with the first identifying data, generating first reference data from the first local media content.

2. A method as defined in claim 1, further comprising installing a meter on the first information presentation device.

3. A method as defined in claim 1, wherein generating the first reference data comprises generating the first reference data via a meter.

4. A method as defined in claim 2, wherein installing the meter further comprises downloading software from a network and executing the software on the first information presentation device.

5. A method as defined in claim 1, further comprising conveying the first reference data to the central facility.

6. A method as defined in claim 1, further comprising bundling the first reference data with the first identifying data.

7. A method as defined in claim 1, wherein generating the first reference data is performed at a time at which a user is not using the first information presentation device.

8. A method as defined in claim 1, wherein generating the first reference data is performed at a time at which a user is unlikely to be using the first information presentation device.

9. A method as defined in claim 1, wherein the first identifying data comprises at least one of a title, an author, an artist, an album, an episode title, a version, a producer, a director, or a copyright holder.

10. A method as defined in claim 1, wherein the first reference data is at least one of a signature or a code.

11. A method as defined in claim 1, wherein the first information presentation device is associated with a panelist in an audience measurement study that has agreed to provide access to the first local media content.

12. A method as defined in claim 1, wherein the first reference data cannot be used to play the first local media content.

13. A method as defined in claim 1, wherein the first reference data includes every type of reference data available for the first local media content.

14. A method as defined in claim 1, wherein the first reference data includes a first type of reference data not yet present in the reference database for the first local media content, but excludes a second type of reference data already present in the reference database for the first local media content.

15. A method as defined in claim 1, wherein the first information presentation device is located at a first geographic location and further comprising locating second local media content on a second information presentation device located at a second geographic location different from the first geographic location.

16. A method as defined in claim 15, further comprising extracting second identifying data associated with the second local media content.

17. A method as defined in claim 16, further comprising querying the central facility with the second identifying data associated with the second local media content.

18. A method as defined in claim 17, further comprising, in response to an indication from the central facility that the reference database lacks validated reference data associated with the second identifying data, generating second reference data from the second local media content.

19. A method as defined in claim 18, further comprising conveying the second identifying data and the second reference data to the central facility.

20. A method as defined in claim 19, further comprising comparing the first reference data to the second reference data.

21. A method as defined in claim 20, further comprising incrementing a count in response to determining that the first and second reference data are substantially similar.

22. A method as defined in claim 21, further comprising validating the first reference data when the count reaches a threshold.

23. A method as defined in claim 20, further comprising decrementing a count in response to determining that the first and second reference data are substantially different.

37. A system to collect reference data into a reference database, comprising:

a set of meters on a corresponding set of geographically disposed information presentation devices to detect local media content accessible at their respective information presentation devices; and

a central facility to receive reference data from the meters and to add the received reference data to the reference database.

38. A system as defined in claim 37, wherein the reference data was not in the reference database prior to receiving the reference data from one of the meters.

39. A system as defined in claim 37, wherein at least one of the meters detects local media content by monitoring at least one of presentation or download activity on a corresponding information presentation device.

40. A system as defined in claim 37, wherein at least one of the meters detects media content by performing a search of a memory of a respective one of the information presentation devices.

41. A system as defined in claim 37, wherein at least one of the information presentation devices comprises a personal computer, a laptop computer, a media center computer, a digital video recorder, a portable computer device, a console gaming system, a removable media player, a set top box, or a cell phone.

42. A system as defined in claim 37, wherein the local media content is non-broadcast media content.

43. A system as defined in claim 37 wherein the local media content is purchased audio content.

44. A system as defined in claim 37, wherein the local media content is purchased MP3 files.

45. A system as defined in claim 37, wherein the local media content is purchased audio-video content.

46. A meter to provide data associated with local media content to a central database, comprising:

a content identifier to search an information presentation device for local media content;

a data extractor to extract identifying information associated with the local media content and to forward the identifying information to a central facility; and

a reference generator to generate reference data associated with the local media content.

49. A meter as defined in claim 46, further comprising a reference bundler to bundle the identifying information with the generated reference data, wherein bundled information is conveyed to the central facility.

55. A meter as defined in claim 46, wherein the local media content is non-broadcast media content.

56. A meter as defined in claim 46, wherein the local media content is purchased audio content.

57. A meter as defined in claim 46, wherein the local media content is purchased MP3 files.

58. A meter as defined in claim 46, wherein the local media content is purchased audio-video content.
