Abstract: The present invention recognizes media content using signatures generated by network devices with limited processing power. An audio signal is prepared for application of a discrete Fourier transform (DFT). Outputs from the DFT include real components and imaginary components that are used to calculate output magnitudes associated with frequency bins. The frequency-amplitude pairs include the output magnitudes and the associated frequency bins. A signature of the audio signal is generated by selecting a predetermined number of frequency-amplitude pairs having dominant output magnitudes. The network devices that generate the signatures may transmit the signatures to a server for analysis. The server may trigger actions in response to detecting known content based on the received signatures matching known signatures.

Abstract: The present invention recognizes media content using signatures generated by network devices with limited processing power. A signature comprises a first set of frequency-amplitude pairs associated with a first piece of content. The signature is compared with stored signatures corresponding to known content. Each of the stored signatures comprises a stored set of frequency-amplitude pairs. The first piece of content is identified as being or including known content in response to the first signature matching a stored signature.
