Abstract

To monitor audio-visual content which includes captions, caption fingerprints are derived from a length of each word in the caption, without regard to the identity of the character or characters forming the word. Audio-visual content is searched to identify a caption event having a matching fingerprint and missing captions; caption timing errors and caption discrepancies are measured.
