Abstract:
1. A multiplexing method for generating bitstreams by coding a moving picture on a basis of a constituent unit of the moving picture, and packet-multiplexing the bitstreams, said multiplexing method comprising: judging whether or not the constituent unit to be coded should be coded as part of a continuous reproduction unit in which bitstreams are structured so as to allow continuous reproduction; determining, for the constituent unit to be coded, a color space that is common within the continuous reproduction unit, when it is judged that the constituent unit to be coded should be coded as part of the continuous reproduction unit; generating bitstreams by coding the constituent unit to be coded according to the determined color space; and packet-multiplexing the bitstreams, wherein in said generating bitstreams, when a color space of the constituent unit to be coded is different from the determined color space, (i) the color space of the constituent unit to be coded is converted into the determined color space, (ii) the constituent unit to be coded that is to be expressed in the converted color space is coded, and (iii) a flag indicating whether or not the color spaces of the bitstreams that have been packet-multiplexed are of only one type is generated.
