摘要： Auxiliary data is transported in a primary data signal by hiding the data in the form of colored noise. The colored noise has a spectrum that simulates the spectrum of the primary data signal. The data to be transported is first converted to a spread spectrum signal. The primary data signal is analyzed to determine its spectral shape. The same spectral shape is imparted to the spread spectrum signal, which is then combined with the primary data signal for transmission. The spectral shaping can be performed using time domain modeling and synthesis such as linear predictive coding or by using subband coding techniques such as fast Fourier transforms. A plurality of different auxiliary information streams can be transported on the primary data signal. By adjusting the gain of individual spread spectrum signal carrier(s) and the power of the colored noise, the auxiliary information stream(s) can be rendered at a desired level at, below or above an interference threshold in the primary data signal.

摘要： Reproduction of a multi-media data signal which is stored on a source media or distributed via a communication network is controlled by inserting master tag data and control tag data into the data signal. A player/recorder inserts an additional generation of control tag information each time a copy of the media is made. If the number of generations of the control tag information is above a threshold value, reproduction of the data signal may be inhibited. For example, if the data signal comprises video data, the player/recorder may only allow playing of the video signal on a display but will not allow recording. The playing and recording of associated signals, such as an audio signal which accompanies a video signal, may also be controlled. The master tag data and control tag data may be provided as spread spectrum signals which are spectrally shaped and power-adjusted according to the data signal to render them imperceptible in the data signal. With encrypted frames of multi-media data, encryption keys may be carried in a key layer with the encrypted data signal or another data signal for use in decryption on a frame by frame basis.

If the number of generations of the control tag information is above a threshold value, reproduction of the data signal may be inhibited.

The playing and recording of associated signals, such as a video signal which accompanies an audio signal, may also be controlled. The master tag data and control tag data may be provided as spread spectrum signals which are spectrally shaped and power-adjusted according to the data signal to render them imperceptible in the data signal. In a graceful degradation scheme, the additional generation of control tag information is provided at a level which is calculated to cumulatively degrade the quality of the data signal according to the number of generations of control tag information.

摘要： Auxiliary data is transported in a conventional audio signal by hiding the data in the form of colored noise. The colored noise has a spectrum that simulates the spectrum of the primary audio signal. The data to be transported is first converted to a spread spectrum signal. The primary audio signal is analyzed to determine its spectral shape. The same spectral shape is imparted to the spread spectrum signal, which is then combined with the primary audio signal for transmission. The spectral shaping can be performed using time domain modeling and synthesis such as linear predictive coding or by using subband coding techniques such as fast Fourier transforms. A plurality of different auxiliary information streams can be transported on the audio signal. By adjusting the gain of individual spread spectrum signal carrier(s) and the power of the colored noise, the auxiliary information stream(s) can be rendered inaudible in the primary audio signal, or at any desired level below or above an audible threshold.

摘要： A system for measuring exposure to a visual display such as a billboard. A transmitter that is proximate to the billboard broadcasts a data signal that carries information relating to the billboard. This information may identify the location of the billboard, the message displayed by the billboard, and time of day. The data signal is provided at a power level that is adapted to reach a pre-defined exposure area in which the billboard can be viewed. A portable receiving device is provided to a defined consumer population to measure the exposure of the consumers to the billboards. The receiving device may be carried or worn by the consumer, or carried in the consumer's vehicle. The receiving device is adapted to recover the data signal and store the information relating to the billboard when the viewer is in the pre-defined exposure area. The time of day and duration of the exposure may also be recorded. The recorded information is subsequently downloading for processing by a central processing facility, e.g., via a telephone line or computer link.

摘要： Broadcast audio is automatically monitored for information of interest. A computer processor has a memory associated therewith for storing a vocabulary of keywords of interest. An audio receiver receives an audio broadcast. A speech recognition system associated with the audio receiver and computer processor detects when one of the keywords appears in a received audio segment. A report generator associated with the computer processor and responsive to the detection of a keyword generates a report detailing the detected keyword and its context. The system is particularly well suited to the verification of commercial messages and to assist in public relations efforts.
