基于QM算术编码器的CX序列的反推原理及实现
Backstepping principle and implementation of CX sequence based on QM arithmetic encoder
摘要
Abstract
The backstepping principle of CX sequence is obtained by the analysis of the flow chart and test sequence about QM arithmetic encoder in ISO/IEC 10918-1 : 1993 (E). Using D, MPS, Qe, the three columns of data in test sequence, and combining probability estimation state machine of QM arithmetic encoder and the minimization principle, the test sequence of QM arithmetic encoder is supplemented with its lacking CX sequence, meanwhile , initial values of MPS and Index is gotten. Then, the obtained data are entered into QM arithmetic encoder and the correctness of produced CX sequence is verified.关键词
