Abstract
A moving picture coding apparatus and method with improved predictability of a moving picture to be subjected to interframe prediction to obtain an improved quality of a coded picture. In a moving picture coding apparatus for performing interframe motion compensated prediction for applying intraframe coding, interframe forward predictive coding and interframe bidirectional predictive coding to code each frame, by determining a prediction frame interval of frames to be subjected to forward prediction on the basis of interframe predictability, a moving picture is coded while the coder is adaptively changing the prediction frame interval in accordance with the predictability.
