Patent ID: 7688471

Claim:
A moving picture coding method for generating a coded stream by coding a moving picture signal on a picture-by-picture basis, wherein said moving picture coding method includes coding a current picture to be coded which is i) included in a random access unit having a plurality of pictures starting with an I-picture in a decoding order and a plurality of parameter sets for decoding the plurality of pictures, and ii) located after the I-picture in a coding order, said moving picture coding method comprises: coding a parameter set selected for decoding the current picture to be coded; second coding the current picture to be coded based on content included in the selected parameter set; and generating a coded stream so that the selected and coded parameter set is located before the coded I-picture in the random access unit including the I-picture, the selected and coded parameter set being unnecessary for the I-picture, and said generating includes avoiding locating the selected and coded parameter set immediately before the current picture to be coded.
