Abstract: A system and method is presented that segregates portions of a video file into distinct sections based on whether the sections contain original content or modified content. For each segment, portion, section or scene with modified content, a compressed file is created which includes at least one instance of a set of frames which includes modified content. For some sections there may be two or more versions of modifications. These alternative versions may be compressed as a single distinct file. This permits efficient edge caching of video files with modified content, for example for selective provision of alternative versions of the video file to various end users in a transmission efficient manner.

Abstract: A method of identifying distinctive objects or images within a digital video comprises the use of one or more pixel (pel) based “pattern” or “feature” recognition protocols.

Abstract: A method of inserting a new image into a dynamic digital video file comprises identifying a target digital video segment into which the new image is to be inserted, projectively transforming the digital video segment from a first state to a second state, the second state being one which defines a substantially undistorted background, primed for new image insertion, and wherein any feature differences as between the first state and the second state are adjustment features; recording segment into data related to the adjustment features; selecting a point of insertion of new image; and blending the new image with the second state of the target digital video segment, weighing the adjustment features against each such that any visual cues which would mark placement of the new images as incongruous are adjusted.
