The present invention discloses a predistortion modulation system for use in satellite systems. A typical apparatus of the invention includes a predistortion processor for predistorting a digital data source signal to reduce transmission distortion and an adaptive algorithm processor for controlling the predistortion processor according to a received a feedback signal derived from the transmitted data source signal. In further embodiments, the non-linear and linear predistortion is adaptively controlled. The invention is particularly useful in a digital cinema satellite system.
