DIGITAL SIGNAL CODING APPARATUS, DIGITAL SIGNAL DECODING APPARATUS, DIGITAL SIGNAL ARITHMETIC CODING METHOD AND DIGITAL SIGNAL ARITHMETIC DECODING METHODIn a bit stream syntax containing compressed video slice data for compressed video data of a5 slice structure, a slice header for compressed video slice data has attached thereto a slice start code, a register reset flag indicating whether aregister value, which designates a status of a codeword occurring in an arithmetic coding process,10 should be reset in the next transmission unit, an initial register value which indicates a register value to be used to start arithmetic coding/decoding to build/decompose the nexttransmission unit, only when the register reset15 flag indicates that the register should not be reset.Fig. 3
