<p>According to a first aspect of the present invention, there is provided an apparatus for coding a moving picture while coding a part of frames of the moving picture into intra-frames (I-pictures), a part of frames sandwiched between contiguous intra-frames into forward predictive frames (P-pictures), and frames sandwiched between a forward predictive frame and another forward predictive frame or an intra-frame into a bidirectionally predictive frames (B-pictures), comprising: a determining means for determining the number of B-pictures between a P-picture and another P-picture or an I-picture based on an output frame rate and a substantial frame rate which is defined as the number of pictures capable of being processed per unit time by the apparatus provided that only I-pictures and P-pictures are coded; and a coding means for coding the B-pictures by treating the B-pictures as frames with no differential data.</p> |
