Abstract

Video is a communications medium that normally brings together moving pictures with a synchronized audio track into a discrete piece or pieces of information. A "piece" of video is variously referred to as a frame, a shot, a scene, a Clip, a program, or an episode; these pieces are distinguished by their length and by their composition. We shall return to the definition of each of these in the section an automatically structuring and indexing digital video. In modern society, Video is commonplace and is usually equated with television, movies, or home Video produced by a Video camera or camcorder. We also accept Video recorded from closed circuit TVs for security and surveillance as part of our daily lives. In short, Video is ubiquitous. Digital Video is, as the name suggests, the creation or capture of Video information in digital format. Most Video produced today, commercial, surveillance, or domestic, is produced in digital form, although the medium of Video predates the development of digital computing by several decades. The essential nature of Video has not changed with the advent of digital computing. It is still moving pictures and synchronized audio. However, the production methods and the end product have gone through significant evolution, in the last decade especially.
