Abstract: PURPOSE:To reduce coding information quantity while suppressing coding distortion due to interpolation to a small value by calculating the coding distortion caused by interleaving and calculating the degree of reduction of generated information quantity so as to control the interleaving depending on the relation of quantity of the both. CONSTITUTION:An animate picture signal fed through a line 1000 is inputted simultaneously to a subtractor 10 and a discrimination circuit 16. A forecast error signal being an output of the subtractor 10 is fed to an interpolation circuit 14 as the 1st local decoding signal via a delay circuit 11, a quantizing circuit 12 and an adder 13. The discrimination circuit 16 uses the reduction in the quantity of code per block due to interleaving and the coded distortion from the input signal and the forecast signal so as to discriminate whether or not the interleaving is applied to the said block, and when the coding distortion is large and the reduction is small, no interleaving is applied and executes the interleaving in other cases by applying an interleaving command signal to the interpolation circuit 14 through a line 1600. The interpolation circuit 14 receives the said command signal to generate the 2nd local decoding signal and a forecast signal is obtained by a forecasting circuit 15.
