Abstract
A system and method for hardware agnostic detection of one or more advertisements broadcasted across one or more channels includes extracting a first set of audio fingerprints and a first set of video fingerprints. The method also includes generating a set of digital signature values corresponding to an extracted set of video fingerprints, and normalizing each frame of a pre-determined number of frames of a video. The method also includes scaling each frame of the corresponding pre-determined number of frames of the video clip to a pre-defined scale. Each frame corresponds to the broadcasted media content on the channel. The method also includes trimming a first pre-defined region and a second pre-defined region of each frame by a pre-defined percentage of a frame width, a frame height and a pre-defined number of pixels in each frame.
