FIELD OF THE DISCLOSURE

This disclosure relates generally to signatures, and, more particularly, to methods and apparatus to identify media.

BACKGROUND

Media (e.g., sounds, speech, music, video, etc.) can be represented as digital data (e.g., electronic, optical, etc.). Captured media (e.g., via a microphone and/or camera) can be digitized, stored electronically, processed and/or cataloged. One way of cataloging media (e.g., audio information) is by generating a signature (e.g., a fingerprint, watermarks, audio signatures, audio fingerprints, audio watermarks. etc.). Signatures are digital summaries of media created by sampling a portion of the media signal. Signatures have historically been used to identify media and/or verify media authenticity.
