    Abstract: Example methods, apparatus and articles of manufacture to perform audio watermark decoding are disclosed. A disclosed example method includes receiving an audio signal including an audience measurement code embedded therein using a first plurality of frequency components, sampling the audio signal, transforming the sampled audio signal into a first frequency domain representation, determining whether the code is detectable in the first plurality of frequency components of the first frequency domain representation, and when the code is not detected in the first plurality of frequency components, examining a second plurality of frequency components of a second frequency domain representation to determine whether the code is detected, the second plurality of frequency components being offset from the first plurality of frequency components by a first offset, the first offset corresponding to a sampling frequency mismatch.

    Abstract: Methods, apparatus, systems and articles of manufacture (e.g., physical storage media) to utilize audio watermarking for people monitoring are disclosed. Example people monitoring methods disclosed herein include determining, at a user device, whether a first trigger condition for emitting an audio watermark identifying at least one of the user device or a user of the user device is satisfied. Such example methods also include, in response to determining that the first trigger condition is satisfied, providing a first audio signal including the audio watermark to an audio circuit that is to output an acoustic signal from the user device.

    Abstract: Methods and systems for robust watermark insertion and extraction for digital set-top boxes are disclosed and may include descrambling, detecting watermarking messages in a received video signal utilizing a watermark message parser, and immediately watermarking the descrambled video signal utilizing an embedded CPU. The embedded CPU may utilize code that may be signed by an authorized key, encrypted externally to the chip, decrypted, and stored in memory in a region off-limits to other processors. The video signal may be watermarked in a decompressed domain. The enabling of the watermarking may be verified utilizing a watchdog timer. The descriptors corresponding to the watermarking may be stored in memory that may be inaccessible by the main CPU. The watermark may comprise unique identifier data specific to the chip and a time stamp, and may be encrypted utilizing an on-chip combinatorial function.
