Media monitoring using multiple types of signatures
First Claim
1. A media monitoring method comprising:
- reporting, from a device meter to a data processor, media signatures of a first type to monitor media presented by a media device, the media signatures of the first type being generated by the device meter from a sensed signal;
after receiving, from the data processor, an indication that a first media signature of the first type is associated with first reference media, generating, at the device meter, media signatures of a second type, different from the first type, from the sensed signal to continue monitoring the media presented by the media device; and
in response to detecting, at the device meter, that a source of the media presented by the media device has changed, generating the media signatures of the first type to continue monitoring the media presented by the media device.

Abstract
Media monitoring using multiple types of signatures is disclosed. Example media monitoring methods disclosed herein include reporting media signatures of a first type to monitor media presented by a media device, the media signatures of the first type being generated by a device meter from a sensed signal. Disclosed example media monitoring methods also include, after receiving an indication that a first media signature of the first type is associated with first reference media, generating media signatures of a second type, different from the first type, from the sensed signal to continue monitoring the media presented by the media device. Disclosed example media monitoring methods further include, in response to detecting that a source of the media presented by the media device has changed, generating the media signatures of the first type to continue monitoring the media presented by the media device.

8. A tangible machine readable medium comprising machine readable instructions which, when executed, cause a machine to at least:
-
generate media signatures of a first type to monitor media presented by a media device, the media signatures of the first type being generated from a sensed signal; generate media signatures of a second type, different from the first type, from the sensed signal to continue monitoring the media presented by the media device after receiving an indication that a first media signature of the first type is associated with first reference media; and generate the media signatures of the first type to continue monitoring the media presented by the media device in response to detecting that a source of the media presented by the media device has changed. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A device meter comprising:
-
a signature reporter to report, to a data processor, media signatures of a first type to monitor media presented by a media device, the media signatures of the first type being generated from a sensed signal; and a signature generator to; generate the media signatures of the first type; generate media signatures of a second type, different from the first type, from the sensed signal to continue monitoring the media presented by the media device after receiving, from the data processor, an indication that a first media signature of the first type is associated with first reference media; and revert to generating the media signatures of the first type to monitor the media presented by the media device in response to detecting that a source of the media presented by the media device has changed. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. An apparatus comprising:
-
means for reporting media signatures of a first type to monitor media presented by a media device, the media signatures of the first type being generated from a sensed signal; means for generating media signatures of a second type, different from the first type, from the sensed signal to continue monitoring the media presented by the media device after receiving an indication that a first media signature of the first type is associated with first reference media; and means for reverting to generating the media signatures of the first type to continue monitoring the media presented by the media device in response to detecting that a source of the media presented by the media device has changed.
