Claim 8:
9. A data compression method, comprising:
obtaining a plurality of values of a parameter and respective occurrence probabilities of the plurality of values;
comparing the respective occurrence probabilities with a predetermined threshold, to determine, from the plurality of values, a first set of values with the respective occurrence probabilities less than the predetermined threshold and a second set of values with the respective occurrence probabilities greater than or equal to the predetermined threshold;
preprocessing the first set of values; and
encoding the second set of values and the preprocessed first set of values,
wherein the preprocessing the first set of values comprises:
resetting the respective occurrence probabilities of the first set of values so that: a sum of the reset respective occurrence probabilities of the first set of values is no greater than a second minimum value in the second set of values, and the first set of values can form a balanced binary tree.
