Claim 7:
8. At least one non-transitory computer readable medium comprising computer readable instructions that, when executed by at least one processor of a device meter, cause the device meter to at least:
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 by the device meter from a sensed signal, the sensed signal from a sensor that is to sense an output of the media device;
after receipt of an indication from the data processor that a first media signature of the first type is associated with first reference media, 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; and
in response to detection that a source of the media presented by the media device has changed, generate the media signatures of the first type to continue monitoring the media presented by the media device.
