In order to locate the identification information of an unknown video, a video signature can be generated by identifying shot changes within the video. A shot change may be defined by a large change in image information between two consecutive frames N and N+1 of video together with a small change in image information between frame N and the previous frame N-1. Information from shot changes can then be used to generate a video signature. This video signature can be easily reproduced on different versions of the same video.

[0010] Such video signatures may be compared to a video signature database that includes video signatures for a library of reference videos and identifying information (eg, ...

Abstract

Video signatures are generated when a small change in video information between consecutive frames N-1 and N is followed by a large change in video information between consecutive frames N and N+1. Information from frames N and / or N+1 is used to form a video signature.

Description

Background technique [0001] Identification information, such as metadata, is often not included with digital video content. Often this results in the viewer being unable to identify the title, year of production, type of content, or any other information he or she might expect for a satisfactory viewing experience.
