1. A backward adaptation apparatus comprising:
a first storage apparatus, comprising:
a first buffer, allocated in the first storage apparatus and arranged to store a first probability table involved in processing of a first frame; and
a second buffer, allocated in the first storage apparatus and arranged to store a second probability table selectable for processing of a second frame following the first frame;
a count table maintenance apparatus, arranged to maintain a count table,
wherein the count table maintenance apparatus comprises at least one count data updating circuit shared for dynamically updating the count table during the processing of the first frame;
a probability table storage apparatus; and
a backward probability update circuit, arranged to refer to information of the count table and information of the first probability table
to calculate the second probability table in the second buffer at an end of the processing of the first frame, and
store the second probability table into the probability table storage apparatus.
