Abstract:
1. A coding device that codes a moving picture on a block basis, said coding device comprising: a header information generating unit configured to receive a moving picture signal and to generate, based on the moving picture signal, a header parameter and a header code value signal corresponding to the header parameter according to a syntax structure signal, the header parameter and the header code value signal being common to a plurality of blocks of moving picture signals; a header information coding unit configured to perform non-arithmetic coding on the header code value signal selectively with either a fixed length code or a variable length code according to the syntax structure signal, so as to generate a header stream; a frame coding unit configured to code, on the block basis, the moving picture signal with reference to the header parameter so as to generate a frame code value signal; an arithmetic coding unit configured to perform only arithmetic coding on the frame code value signal so as to construct a frame stream; and a multiplexer configured to multiplex the header stream and the frame stream so as to construct a picture coded signal, wherein the header information coding unit includes:
