Abstract: Methods and apparatus to generate and use content-aware watermarks are disclosed herein. An example disclosed method includes detecting a watermark in a first media composition, the watermark encoded with a word present in an audio track of the first media composition, the word audible during playback of the audio track. The example method also includes retrieving the word from the watermark. The example method also includes determining whether the word retrieved from the watermark matches a keyword, and presenting a second media composition when the word matches the keyword.

Abstract: Example methods, apparatus, and articles of manufacture determine compliance with usage guidelines of an audience measurement system. Initially, location information associated with an audience member is obtained. It is then determined whether the audience member is in compliance with the usage guidelines based on the location information. Media monitoring information corresponding to the location information is then tagged as non-compliant if the audience member is not in compliance with the usage guidelines.

Abstract: Methods and apparatus to monitor media exposure are disclosed. An example implementation includes accessing a meter identifier and first audio received from a wearable bracelet meter, the meter identifier uniquely associated with the wearable bracelet meter. Whether the first audio substantially matches second audio received at a second meter is determined. In response to determining that the first audio and the second audio substantially match, the meter identifier associated with the wearable bracelet meter and at least one of the first audio or the second audio are stored.

Abstract: Methods and apparatus to generate and use content-aware watermarks are disclosed herein. In a disclosed example method, media composition data is received and at least one word present in an audio track of the media composition data is selected. The word is then located in a watermark.

Abstract: Methods and apparatus to monitor media exposure are disclosed. An example implementation includes transmitting a start signal from a mailable meter to at least one mailable meter to at least one wearable meter; receiving a first audio at the mailable meter upon transmission of the start signal; receiving a second audio at the at least one wearable meter upon reception of the start signal; deriving a signature of the first received audio at the mailable meter; deriving a signature of the second received audio at the at least one wearable meter; transmitting the signature of the second received audio and an identification number from the at least one wearable meter to the mailable meter; and storing the signature of the first received audio and the identification number at the mailable meter as audience measurement data if the signature of the first received audio and the signature of the second received audio correlate.

Abstract: Example methods, apparatus, and articles of manufacture to collect metering information associated with media presented by portable and computer media presentation devices are disclosed. A disclosed example apparatus includes a headset configured to be communicatively coupled to a media presentation device and a speaker coupled to the headset and configured to emit audio based on audio information received from the media presentation device. The example apparatus also includes a metering information generator coupled to the headset and configured to be communicatively coupled to the media presentation device to receive the audio information and generate metering information associated with the received audio information.

Abstract: Example methods and apparatus for associating media devices with a demographic composition of a geographic area are disclosed. A disclosed example method includes receiving a plurality of Internet Protocol addresses assigned to a media device associated with a panel member, determining a most used Internet Protocol address from the plurality of Internet Protocol addresses, accessing geographic information and determining a geographic location corresponding to the most used Internet Protocol address, accessing demographic information and determining a demographic profile associated with the geographic location, and associating at least one of the geographic location or the demographic profile with the media device.

Abstract: Methods and apparatus to maintain audience privacy while determining viewing of video-on-demand (VOD) programs are disclosed.

Abstract: Apparatus, methods, and articles of manufacture for media monitoring are disclosed. In particular, the example apparatus, methods, and articles of manufacture determine a media source type associated with a media signal and select an encoding or decoding mode based on the media source type. An encoding operation encodes the media signal using the selected encoding mode and a decoding operation decodes the media signal using the selected decoding mode.

Abstract: Example methods, apparatus, and articles of manufacture determine compliance with usage guidelines of an audience measurement system. Initially, location information associated with an audience member is obtained. It is then determined whether the audience member is in compliance with the usage guidelines based on the location information. Media monitoring information corresponding to the location information is then tagged as non-compliant if the audience member is not in compliance with the usage guidelines.

Abstract: Methods and apparatus to monitor media exposure in vehicles are disclosed. An example implementation includes collecting audience measurement data with a media monitoring device fixed in a vehicle and transmitting the audience measurement data from the media monitoring device to a shuttle located within the vehicle, the shuttle being incapable of collecting audience measurement data independent of the media monitoring device.

Abstract: Methods and apparatus to count persons in a monitored environment are disclosed. An example apparatus to count the number of people in a monitored environment is described, which includes an image sensor to collect a plurality of pixels, a pseudorandom number generator to pseudorandomly select at least one of a row of the pixels or a column of the pixels, a reader to read first pixel data generated by first pixels of the image sensor at a first time, the first pixels located in at least one of the row of the pixels or the column of the pixels, a comparator to compare the first pixel data with second pixel data generated by the first pixels at a second time different than the first time to generate first change values, and a counter to generate a count of persons based on the first change values.
