<p>A period M of a picture of which picture coding type is I or P in a video input is changed like 2 and 3. CUR_M shows the present number of M. MAX_M, namely, the maximum number of M in a sequence which continues with respect to the time is equal to 3. A frame delay of MAX_M is given to a picture (1B, 2B, or the like) of which picture coding type is B. A frame delay of (MAX_M - CUR_M) is given to a picture (1I, 2I, or the like) of which picture coding type is I. In this manner, a sequence of a coding order is formed and a predictive encoding is performed, thereby forming a bit stream. <IMAGE></p> |
