Abstract:
1. A coding method for coding a moving picture for allowing switching of moving image streams, the coding method comprising: assigning an exclusive continuous picture number to the current picture, the picture number being assigned to the current picture to identify the current picture, and a value of the picture number being incremented by 1 for a reference picture following the current picture; coding the picture number of the current picture; and judging whether or not (i) the current picture is a picture capable of switching the moving image streams and (ii) all reference picture release information is to be coded, the all reference picture release information instructing a decoder to release all reference pictures stored in a memory of the decoder, wherein, when said judging judges that the current picture is a picture capable of switching the moving image streams and judges that the all reference picture release information is to be coded, the coding method performs: wherein, when said judging judges that the current picture is not a picture capable of switching the moving image streams and judges that the all reference picture release information is not to be coded, the coding method performs: wherein, when the current picture, which is a picture capable of switching moving image streams, is assigned the picture number of “0” and the picture number of the following picture to be coded is “0,” there is no error even though the picture numbers of the current picture and the following picture are not continuous.
