    摘要: Methods and apparatus for identifying a digital audio signal are described. An example apparatus for identifying a digital audio signal includes an input to receive the digital audio signal, which includes data from a broadcast or a stored digital program signal. The example apparatus also includes a detector to receive the digital audio signal from the input and determine whether the received digital audio signal is uncompressed as received at the input; a decoder to receive the digital audio signal from the detector when the digital audio signal is compressed as received at the input and identify any first program-identifying code in an auxiliary field of the compressed digital audio signal; and a code reader to receive the digital audio signal from the detector when the digital audio signal is uncompressed as received at the input and receive the digital audio signal from a decompressor when the digital audio signal is compressed as received at the input. Additionally, the code reader is to identify any second program-identifying code in a decompressed or uncompressed portion of the digital audio signal when the first program-identifying code is not identified in the auxiliary field or when the digital audio signal is uncompressed as received at the input.

    摘要: Methods and apparatus to monitor reception of programs and content by broadcast receivers are disclosed. An example method disclosed herein to monitor reception of a broadcast program by a broadcast receiver located in a statistically selected site comprises retrieving an audience measurement data packet from the broadcast receiver in order to identify the broadcast program, detecting a code embedded in the broadcast program in order to identify the broadcast program, extracting a signature from the broadcast program in order to identify the broadcast program, identifying the broadcast program through use of a software agent, and selecting at least one of the audience measurement data packet, the embedded code, the extracted signature or the software agent to identify the received program.

    摘要: A communication method and a data collection and transmission system are provided having at least one remotely located monitoring station. A central computer is arranged for bidirectional communication with each of the monitoring stations. Each of the monitoring stations includes a storage and forward unit for communicating with the central computer and at least one sensor unit for monitoring a predetermined geographically proximate variable and for processing and storing predetermined operational data. The storage and forward unit includes a real time clock that is arranged to accurately maintain a real time indicative signal. A local area network connects the storage and forward unit and each of the sensor units. A coded message having a predetermined sequential data format is used for bidirectional communications between the storage and forward unit and the sensor units. A real-time coded message is provided by the storage and forward unit to the sensor units. The storage and forward unit includes a counter for counting at a predefined rate for identifying a delay time period prior to the transmission of the real-time coded message. Each sensor unit includes a counter for counting at the predefined rate to identify a second time delay period responsive to a received real-time coded message from the storage and forward unit. The real-time coded message includes the first identified time delay period that is combined with the second identified time delay period to determine the current time value by the sensor unit.
