1. A method for segmenting a broadcast data stream comprising:

  • receiving a sample of the broadcast data stream;

    receiving a start time of the sample;

    determining a track identity of the sample;

    determining a relative time offset of the sample from a beginning of the identified track; and

    calculating via a processor an extrapolated start time of the identified track within the broadcast data stream by subtracting the relative time offset from the start time of the sample, wherein the extrapolated start time indicates a boundary between tracks in the broadcast data stream.
