1. A method for use in recognizing the content of a media program, said method comprising the steps of: filtering each first frequency domain representation of blocks of said media program using a plurality of filters to develop a respective second frequency domain representation of each of said blocks of said media program, said second frequency domain representation of each of said blocks having a reduced number of frequency coefficients with respect to said first frequency domain representation; grouping frequency coefficients of said second frequency domain representation of said blocks to form segments; and selecting a plurality of said segments.
