EFFICIENT DELIVERY METHOD FOR DELIVERING ONLINE VIDEO WHERE IN-VIDEO IMAGES ARE ALTERED DYNAMICALLY BASED ON INTERNET DATA OF INDIVIDUAL VIEWER

摘要

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.
