发明名称 DEVICE AND METHOD FOR ENCODING/DECODING ARITHMETIC OF MQ-CODER METHOD
摘要 <p><P>PROBLEM TO BE SOLVED: To provide an MQ-CODER for accelerating processing by simplifying the determination of 'A<Qe (I(CX))'. <P>SOLUTION: If an index (I(CS) is any number other than 0, 6, 7, 8, 14, 15, 16, 17 or 46, 'A<Qe (I(CX))' is not determined to be true. If the index (I(CX)) is 0, 6, 7, 8, 14, 15, 16, 17 or 46, 'A≤Qe(I(CS))' is determined with a 14-bit value except an MSB and an LSB. If 'A≤Qe(I(CX))' is true, 'A<Qe(I(CX))' is also determined to be true. Unless 'A≤Qe(I(CX))' is true, 'A<Qe(I(CX))' is not judged to be true. <P>COPYRIGHT: (C)2004,JPO</p>
