A program delivery system using a compression apparatus capable of compressing incoming video and non-video signals, such as audio and data signals. The system includes a frequency modulator which modulates the incoming audio, data or other non-video signals, unto selected video frequencies. A Fourier transformer generates a set of sinusoidal transform components corresponding to the incoming video, audio, data or other non-video signals, and a selector chooses the most desirable Fourier sinusoidal transforms. A multiplexer multiplexes only the selected Fourier transform components for further processing.
