    摘要: Portable audience measurement architectures and methods for portable audience measurement are disclosed. A disclosed system contains a plurality of portable measurement devices configured to collect audience measurement data from media devices, a plurality of data collection servers configured to collect audience measurement data from the plurality of portable measurement devices, and a central data processing server. A portable measurement device establishes a communication link with a data collection server in a peer-to-peer manner and transfers the collected audience measurement data to the data collection server. Because the portable measurement device is not dedicated to a particular local data collection server, the portable measurement device periodically or a periodically broadcasts a message attempting to find a data collection server with which to establish a communication link.

    摘要: Encoding and decoding methods and apparatus are described to obtain auxiliary information from an audio signal. The auxiliary information uses a plurality of frequency components residing in a plurality of code bands. The audio signal is transformed into a frequency domain representation. Characteristics of frequencies of the frequency domain representation that may contain the auxiliary information are determined. The characteristics of frequencies of the frequency domain representation in a respective one of the code bands that may contain the auxiliary information are normalized across the code band. The normalization is carried out against a characteristic of a frequency in that code band. The normalized characteristics of the frequencies representative of auxiliary information are summed to determine a sum for a frequency representative of auxiliary information. It is determined when the sum is representative of the auxiliary information.
