Systems, devices and methods are provided to automatically identify advertisements or other portions of a broadcast television stream before the stream is distributed via a cable, DBS, IPTV or other medium. The television broadcast is received at the data processing system, and audio content of the television broadcast is analyzed to generate an audio fingerprint of a portion of the audio content. The identified audio fingerprint are compared to audio fingerprints stored in a database to thereby identify the portion of the television broadcast based on the generated audio fingerprint. By identifying the contents of an actual broadcast prior to redistribution of the broadcast, additional actions may be taken that are unique to the identified content.
