Abstract
A system encodes an input video signal by subjecting the input video signal to noise reduction to obtain a noise-reduced signal, and encoding a difference between the noise-reduced signal and a prediction signal to produce an encoded signal. The system then decodes the encoded signal to obtain the prediction signal. In the system, the noise-reduction step comprises arithmetically combining the input video signal with the prediction signal.
