Abstract
Systems and methods for determining the location of advertisements in multimedia assets are disclosed. A method includes obtaining a multimedia asset comprising at least one of video, audio and text, identifying segments of the multimedia asset, and for each segment, determining whether the respective segment represents an advertisement. For each segment that represents an advertisement, the method further includes extracting a predetermined number of fingerprints from the respective segment, submitting, to an advertisement database, the predetermined number of fingerprints, receiving, from the advertisement database, a count of the extracted fingerprints matching fingerprints previously stored in the advertisement database, and determining, based on the count, whether to add an indication that the respective segment is a new advertisement to the advertisement database.
