Abstract
A system for identifying motion video/audio content by means of comparing a video A to a registered video B so as to determine if they are originally the same as each other, wherein said system at least comprises a fingerprint extractor A for fingerprint A from the video A; a fingerprint database for the registered video B; and a matcher which is adapted to search from the fingerprint database for the registered fingerprint B of the video B by means of comparison of fingerprint A with a shifting window of a possible fingerprint B, so as to determine that the video A is visually identical to the video B if a match is found. According to the present invention, the method for extracting a fingerprint data from video/audio signals facilitates the automatic identification, archiving and search of video content, and can be of archiving without the need for human visual inspections.
