A method for comprehensively representing video information in a manner facilitating indexing of the video information, comprising the step of: segmenting a video stream into a plurality of scenes, each of said scenes comprising at least one video frame; dividing, using intra-scene motion analysis, at least one of said plurality of scenes into at least one scene foreground layer and a scene background layer; representing each scene background layer as a mosaic, said background layer mosaic defining a key frame of a respective scene; and representing each of said at least one video frames forming said scene as a difference between initial video frame imagery and a respective portion of said key frame.
