Method and apparatus for identifying media content

Abstract

A computing device executing a server receives a media sample, the media sample having been created from a segment of media content, wherein the media content comprises at least a portion of a work, the segment being a portion of the media content that is less than an entirety of the work, and the media sample comprising a digital fingerprint based on perceptual features of the segment. The computing device compares the media sample to a plurality of reference samples from a plurality of known works to identify a known work of the plurality of known works that corresponds to the work. The computing device then transmits content-related data associated with the known work.

 dividing the media sample into a series of overlapping frames, each frame comprising a distinct digital fingerprint and having a size that corresponds to a size of the reference sample; 
 making comparisons between one or more of the overlapping frames and the reference sample for the known work; and 
 for each comparison between a frame of the media sample and the reference sample of the known work, computing a distance value representative of a similarity between the frame and the reference sample, wherein the known work is determined to correspond to the work if a computed distance value between any frame of the media sample and the reference sample of the known work is lower than a threshold; and 
   transmitting, by the computing device, content-related data associated with the known work.
