Abstract of the Disclosure A television signal which has a motion vector code signal and a prediction error code signal is separated by a demultiplexer into a prediction error code signal and a motion vector code signal. These signals are decoded. A variable delay circuit receives an immediately preceding television signal from a frame memory and produces a prediction signal in response to the decoded motion vector signal. An adder receives the decoded prediction error signal and the prediction signal and produces a decoded television signal. A noise reducer reduces a small interframe variation component of the decoded television signal. This signal is converted by a D/A converter to an analog signal.
