Abstract
A method for encoding image data according to the present invention includes the steps of: specifying a type of a picture in a picture sequence including an I-picture, a P-picture and a B-picture; determining a position of at least one slice header in the picture in accordance with the type of the picture; and inserting the at least one slice header at the position determined in the determining step, wherein the position of the slice header is determined so that at least one of the relationships N.sub.i >N.sub.b and N.sub.p >N.sub.b is satisfied, where N.sub.i denotes the number of slices in the I-picture, N.sub.p denotes the number of slices in the P-picture and N.sub.b denotes the number of slices in the B-picture.
