1. 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 comprises the following steps performed when coding a current picture to be coded which is included in a random access unit including: pictures belonging to a group of pictures starting with a first I-picture which is a first random access point and ending with a picture located immediately-before a second I-picture which is a second random access point; and parameter sets for decoding pictures in the random access unit, the current picture being located after the first I-picture in coding order, said moving picture coding method comprising:
a first coding step of coding a parameter set selected for decoding the current picture to be coded;
a second coding step of coding the current picture to be coded based on the contents included in the selected parameter set; and
a coded stream generating step of generating a coded stream so that the selected and coded parameter set is located before the coded first I-picture in the random access unit including the first I-picture, the selected and coded parameter set being unnecessary for the first I-picture.
