Abstract: Example methods and apparatus to measure exposure to broadcast signals having embedded data are disclosed. Example meters disclosed herein are to decode a watermark from a first audio signal to obtain an identifier of a broadcast station, and query a data structure based on (i) the identifier of the broadcast station obtained from the watermark and (ii) a location, the query to obtain a transmission frequency of a broadcast signal corresponding to the audio signal. Disclosed example meters are also to tune a radio to the transmission frequency of the broadcast signal, and compare the first audio signal with a second audio signal from the radio to verify an identity of the broadcast station.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed for watermark outage detection. Example methods include evaluating an onset time and duration of a detected watermark outage based on a model of expected watermark outages to determine whether the detected watermark outage corresponds to at least one of the expected watermark outages represented in the model. Example methods further include generating an alert in response to determining the detected watermark outage does not correspond to at least one of the expected watermark outages included in the model, and suppressing the alert in response to determining the detected watermark outage corresponds to the at least one of the expected watermark outages represented in the model.

Abstract: Example methods and apparatus to measure exposure to broadcast signals having embedded data are disclosed. An example broadcast signal exposure meter includes a first decoder to obtain an identifier of a broadcast station from an audio signal output by an end user broadcast receiver, a radio to tune to a broadcast signal from the broadcast station associated with the identifier of the broadcast station, a second decoder to obtain embedded data from the broadcast signal, the embedded data representing media contained in the broadcast signal, and an interface to provide the embedded data to a server, the server to determine audience measurement information for the media based on the provided embedded data.
