First Claim
Patent Images
1. A processor-based method for producing supplemental information for media containing embedded audio codes, wherein the codes are read from an audio portion of the media, the method comprising the steps of:
- receiving the audio codes at an input from a data network, said audio codes being received from a device during a first time period, said audio codes representing a first characteristic of the audio portion;
receiving semantic audio signature data at the input from the data network, said semantic audio signature data being received from the device for the first time period, wherein the semantic audio signature comprises at least one of temporal, spectral, harmonic and rhythmic features relating to a second characteristic of the media content; and
successively associating the semantic audio signature data to the audio codes in a processor for the first time period.

Abstract
System, apparatus and method for determining semantic information from audio, where incoming audio is sampled and processed to extract audio features, including temporal, spectral, harmonic and rhythmic features. The extracted audio features are compared to stored audio templates that include ranges and/or values for certain features and are tagged for specific ranges and/or values. The semantic information may be associated with audio codes to determine changing characteristics of identified media during a time period.
