摘要： A method and apparatus is disclosed for incorporating secondary data (528) for transmission as part of or concurrently with network data (532). In one embodiment, the secondary data (528) comprises communication system data for use in controlling or monitoring a communication system. In one example embodiment, the secondary data (528) is utilized to control the transmit timing of the network data (532) to thereby jitter modulate the secondary data (528) into the transmission of the network data (532). By monitoring the timing variation, or jitter, of the received network data signal, the secondary data (528) may be recovered. In one embodiment, the secondary data (528) is encoded to reduce the amount of time variation, i.e. , jitter, that occurs when tranmitting the network data (532). Decoding may occur upon reception of the time adjusted network data signal. In one embodiment, the encoding comprises CDMA type encoding utilizing one or more orthogonal codes.

摘要： Auxiliary data (x(m)) is transported in a primary data signal (s(t)) 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 d(t). 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 (88, 94) or by using subband coding techniques such as fast Fourier transforms (174). A plurality of different auxiliary information streams (280, 290, 300) can be transported on the primary data signal. By adjusting the gain (287, 297, 307, 309) of individual spread spectrum signal carrier(s) and the power (96) of the colored noise, the auxiliary information stream(s) can be rendered at any desired level below or above an interference threshold in the primary data signal.

摘要： Auxiliary data (x(m)) is transported in a conventional audio signal (s(t)) by hiding the data in the form of colored noise (y(t)). The colored noise has a spread spectrum that simulates the spectrum of the primary audio signal. The data to be transported is first converted to a spread spectrum signal (p(n)). The primary audio signal is analyzed to determine its spectral shape (88). The same spectral shape is imparted to the spread spectrum signal (94), which is then combined with the primary audio signal for transmission (100). The spectral shaping can be performed using time domain modeling and synthesis such as linear predictive coding (88) 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 (98), 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.
