1. A high-efficiency encoder comprising:

  • means for segmenting a digitized video signal into blocks of a predetermined size, and for encoding them; and

    prediction means for creating an intra-field or an intra-frame in which motion-compensation prediction is not performed, for every n fields or frames (n is an arbitrary integer not less than

         2), and for performing motion-compensation prediction with an intra-field or an intra-frame on each block for the succeeding (n−

    1) fields or (n−

    1) frames.
