The present invention discloses methods and systems for providing broadcast ad identification. Methods include the steps of: providing fingerprint signatures of each frame in a broadcast video; and designating at least two repeat fingerprint signatures upon detecting at least one fingerprint-signature match from the signatures. Preferably, methods further include: prior to the designating, determining whether the fingerprint signatures correspond to a known ad based upon detecting at least one fingerprint-signature match of the fingerprint signatures with pre-indexed fingerprint signatures of pre-indexed ads. Preferably, method further include: creating segments of the fingerprint signatures, ordered according to a timeline temporal proximity of the fingerprint signatures, by grouping at least two fingerprint signatures based on a repeat temporal proximity of at least two repeat fingerprint signatures respective of at least two fingerprint signatures. Preferably, methods further include detecting at least one ad candidate based on an occurrence of at least one repeat segment. |
