Abstract
A communication system (500) for transmitting and receiving radio frequency (RF) signals includes a base station (505) for transmitting an RF signal including at least compressed data and a plurality of correction factors, wherein the compressed data includes two-dimensional transformed image data which has been compressed by the base station (505) utilizing a plurality of orthogonal functions. The communication system (500) further includes a data communication receiver (510) coupled to the base station (505) for receiving the RF signal and for generating one-dimensional transformed image data therefrom by performing a one-dimensional transformation of the two-dimensional transformed image data utilizing the plurality of orthogonal functions. The data communication receiver (510) includes a controller (1025) for adding the plurality of correction factors to the one-dimensional transformed image data to generate a plurality of column signals which drive an active-addressed, rms-responding display (100).
