Patent ID: 8503991

Claim:
A method to monitor media delivered over wireless communication networks, comprising: emulating first and second wireless devices being at least one of from different manufacturers or of different models, the first emulated wireless device to decode a first media encoding format associated with at least one of a first manufacturer or a first model of the first emulated wireless device, and the second emulated wireless device to decode a second media encoding format different from the first media encoding format and associated with at least one of a second manufacturer or a second model of the second emulated wireless device; receiving first media via the first emulated wireless device and second media via the second emulated wireless device, the first media encoded using the first media encoding format, the second media encoded using the second media encoding format, and the first and second media corresponding to the same media content; storing a first reference exact signature of a portion of the first media received at the first emulated wireless device and a first reference similarity signature of the same portion of the first media to monitor exposure to the media content via a third wireless device being at least one of from the same first manufacturer or of the same first model as the first emulated wireless device, the first reference exact signature to confirm exposure to the media content via the third wireless device when a panel metering signature from the third wireless device matches the first reference exact signature within a threshold, and the first reference similarity signature to confirm exposure to the media content via the third wireless device when the panel metering signature is relatively more similar to the first reference similarity signature than to another reference similarity signature unrelated to the first media; and storing a second reference exact signature and a second reference similarity signature of a portion of the second media received at the second emulated wireless device to monitor exposure to the media content via a fourth wireless device being at least one of from the same second manufacturer or of the same second model as the second emulated wireless device.
