Video compression is a process of reducing the amount of digital data used to represent a sequence of images normally varying in time and intended to portray motion subject to the requirements that the quality of the reconstructed video is sufficient for a certain application and the complexity of the computation involved is appropriate for that application.
Some researchers, for example, Shi and Sun Microsystems (now Oracle) use the term video to refer exclusively to image frames and sequences associated with the visible band of the electromagnetic spectrum while others, for example, Tekalp refer exclusively to sequences.
