Abstract

Media monitoring using multiple types of signatures is disclosed. Example methods disclosed herein include sending a first indication to a device meter to indicate that media monitored by the meter corresponds to first reference media in response to determining that a media signature of a first type reported by the meter matched a first reference signature associated with the first reference media. Disclosed example methods also include, after sending the first indication, comparing media signatures of a second type reported by the meter with reference signatures of the second type associated with the first reference media. Disclosed example methods further include, in response to determining that the media signatures of the second type fail to match the reference signatures of the second type, sending a second indication to the meter to indicate that the media monitored by the meter no longer corresponds to the first reference media.

Claims

1. A media monitoring method comprising:

sending a first indication to a device meter to indicate that media monitored by the device meter corresponds to first reference media in response to determining, with a processor, that a media signature of a first type reported by the device meter matched a first reference signature associated with the first reference media;

after sending the first indication, comparing, with the processor, media signatures of a second type reported by the device meter with reference signatures of the second type associated with the first reference media; and

in response to determining, with the processor, that the media signatures of the second type fail to match the reference signatures of the second type, sending a second indication to the device meter to indicate that the media monitored by the device meter no longer corresponds to the first reference media.
