Abstract: Methods, apparatus, systems and articles of manufacture (e.g., physical storage media) to verify radio station watermarking with software defined radios are disclosed. Example methods disclosed herein to verify watermarking of radio station broadcasts include calibrating a notch filter to attenuate a first radio station broadcast signal. Disclosed example methods also include tuning a software defined radio to demodulate a second radio station broadcast signal from an output of the notch filter, the second radio station broadcast signal different from the first radio station broadcast signal. Disclosed example methods further include processing, with a watermark decoder, audio data resulting from the tuning of the software defined radio to verify watermarking of the second radio station broadcast signal.

Abstract: A second screen system comprises a first screen that renders a first content comprising watermarks of a first type and watermarks of a second type. The watermarks of the first type are captured by a second screen that reacts to these watermarks. The second screen displays information to a user and receives user input. The second screen also watermarks a second content with watermarks of the second type and renders the second content. A third device captures watermarks of the second type in both the first content and the second content. Since the watermarks embedded by the second screen can depend on the user's actions, the third device can indirectly react to the user's actions.

Abstract: Methods and apparatus to validate a tag for media are disclosed. An example method includes obtaining first identification information extracted from a tag distributed with media presented at a presentation location, obtaining second identification information determined from at least one of a) inherent information of at least one of audio or video of the media presented at the presentation location or b) a watermark embedded in at least one of the audio or the video of the media presented at the presentation, comparing the first identification information with the second identification information, and when first identification information does not substantially match the second identification information, preventing the tag from being used to report exposure of the media.

Abstract: Methods and apparatus to verify and/or correct media lineup information are disclosed. An example method includes comparing presentation data representative of media output by a first set top box (STB) to reference data corresponding to a first station to determine whether the media presentation data corresponds to the reference data, the presentation data collected while the first STB was tuned to a first channel. The method further includes determining a second station that corresponds to the presentation data when the presentation data does not correspond to the reference data. The method further includes correcting a first channel map that relates the first channel to the first station by relating the first channel to the second station to create a second channel map, and correcting clickstream data that represents commands to other STBs using the second channel map.
