Claim:
1. An image coding method comprising: a video layer of generating a coded stream by coding an image composed of one or more pictures; and a system layer of generating a system stream for transmitting or storing the coded stream, said video layer comprising said system layer comprising wherein said system layer is compliant with MPEG-2 Systems, said coding includes, in the case where the format of the image is the left-right mixed format, coding the image that includes the base layer and the enhancement layer and that has the left view image area and the right view image area in each picture, to generate the coded stream, said multiplexing includes (i) in the case where said video layer is compliant with a multiview video coding scheme in the MPEG-2 Systems, inserting the identifier in a first descriptor defined for the multiview video coding scheme in the MPEG-2 Systems, and multiplexing the coded stream and the first descriptor that includes the identifier, to generate the system stream, and (ii) in the case where said video layer is compliant with a scalable video coding scheme in the MPEG-2 Systems, inserting the identifier in a second descriptor defined for the scalable video coding scheme in the MPEG-2 Systems, and multiplexing the coded stream and the second descriptor that includes the identifier, to generate the system stream, the first descriptor includes attribute information of the coded stream obtained by coding the image according to the multiview video coding scheme, and the second descriptor includes attribute information of the coded stream obtained by coding the image according to the scalable video coding scheme, and in said multiplexing, (i) in the case where said video layer is compliant with a multiview video coding scheme in the MPEG-2 Systems, the identifier is inserted (a) between maximum_bitrate and view_order_index_min or (b) after no_prefix_nal_unit_present in the first descriptor, and (ii) in the case where said video layer is compliant with a scalable video coding scheme in the MPEG-2 Systems, the identifier is inserted (a) between dependency id and quality_id_start or (b) after no_sei_nal_unit_present in the second descriptor.
