Abstract

A method and an apparatus are set forth for encoding and decoding video to achieve bandwidth compression. In one form of the disclosure, two video signals (810, 850), representative of different images, can be transmitted using only the bandwidth (880) generally allocated to a single video signal, with little or no perceived degradation of image quality. In another form of the disclosure, motion indicative signals (970) are used in a technique that dynamically modifies the frequency band information to be stored and/or transmitted.
