Abstract:
1. A moving picture coding apparatus comprising: an obtainment unit operable to obtain N color component pictures that compose one picture, where N is an integer that is 2 or greater; N coding units, each of which is operable to code, in one of intra-picture prediction coding and inter-picture prediction coding, a corresponding one of the N color component pictures, said N coding units being provided so as to correspond to the N color component pictures; and a signal multiplexing unit operable to multiplex N bit streams outputted from said N coding units into one bit stream signal, and to output the bit stream signal, wherein said N coding units are operable to individually use respective prediction modes or commonly use a prediction mode for the intra-picture prediction coding or the inter-picture prediction coding, said signal multiplexing unit is operable to insert, in the bit stream signal, a prediction mode flag indicating correspondence between the N color component pictures and prediction modes to be used for one of the intra-picture prediction coding and the interpicture prediction coding, the prediction mode flag includes information indicating whether or not the N color component pictures have been coded independently, and the prediction mode flag indicates one of: (i) that each of the N color component pictures has been coded in an independent prediction mode; and (ii) that the N color component pictures have been coded in a common prediction mode.
