DIGITAL SIGNAL CODING APPARATUS, DIGITAL SIGNAL DECODINGAPPARATUS, DIGITAL SIGNAL ARITHMETIC CODING METHOD ANDDIGITAL SIGNAL ARITHMETIC DECODING METHODIn a bit stream syntax containing compressedvideo slice data for compressed video data of aslice structure, a slice header for compressedvideo slice data has attached thereto a slice startcode, a register reset flag indicating whether aregister value, which designates a status of acodeword occurring in an arithmetic coding process,should be reset in the next transmission unit, aninitial register value which indicates a registervalue to be used to start arithmeticcoding/decoding to build/decompose the nexttransmission unit, only when the register resetflag indicates that the register-should not bereset.Fig. 3
