A = Qe(S)

Renorm_e

interlinked in a manner which provides probability estimates based on approximate symbol counts derived from the

arithmetic coder renormalization. Some of these sequences are used during the initial "learning" stages of probability

estimation; the rest are used for "steady state" estimation.

Qe value and two Next_Index values. The Next_Index_MPS gives the index to the new probability estimate after an MPS

renormalization; the Next_Index_LPS gives the index to the new probability estimate after an LPS renormalization. Note

that both the index to the estimation state machine and the sense of the MPS are kept for each context-index S. The sense

of the MPS is changed whenever the entry in the Switch_MPS is one.

an MPS sense of zero and a Qe index of zero in Table D.3.
