Abstract
Progressively scanned specific frames that exist for every predetermined period in a moving picture signal is encoded by infra-frame processing or by uni-directional prediction using other encoded specific frames and by orthogonal transform at the 2 -th (n being an integer) order in the vertical direction, to produce a first bit stream. Frames or fields of the moving picture signal other than the specific frames are predicted by using a preceding reference frame and/or an upcoming reference frame, to produce a predictive error signal for each field. The predictive error signal is encoded by orthogonal transform at the 2 -th order in the vertical direction to produce a second bit stream. The first and second bit streams are alternatively stored in a storage medium. Specific frames that exist for every predetermined period in bit streams are decoded by inverse orthogonal transform at the 2 -th order in the vertical direction and by infra-frame processing or by uni-directional prediction using other encoded specific frames, to reproduce a moving picture signal for each progressively scanned frame. A predictive error signal of frames or fields of the bit streams other than the specific frames is decoded by inverse orthogonal transform at the 2 -th order in the vertical direction. The frames or fields of the moving picture signal other than the specific frames are predicted by using a preceding reference frame and/or an upcoming reference frame, to reproduce a moving picture signal.
