Abstract
A method and apparatus for recognizing broadcast information, the method including the steps of receiving a set of broadcast information; converting the set of broadcast information into a frequency representation of the set of broadcast information; dividing the frequency representation into a predetermined number of frequency segments, each frequency segment representing one of the frequency bands associated with the semitones of the music scale; forming an array, wherein the number of elements in the array correspond to the predetermined number of frequency segments, and wherein each frequency segment with a value greater than a threshold value is represented by binary 1 and all other frequency segments are represented by binary 0; comparing the array to a set of reference arrays, each reference array representing a previously identified unit of information; determining, based on the comparison, whether the set of broadcast information is the same as any of the previously identified units of broadcast information.
