Abstract
A method for subdividing an interval during entropy decoding for a bitstream representing a set of video pictures is provided. A sub-interval value is computed by (i) performing an initial right bit-shifting operation on a probability estimator value to reduce a length in bits of the probability estimator value, (ii) multiplying the right bit-shifted probability estimator value by a range value representing the interval, (iii) performing another right bit-shifting operation on a result of the multiplication, and (iv) adding a constant value to a result of the other right bit-shifting operation, wherein the probability estimator value is associated with a probability of a bin having a particular value. The sub-interval value computed based on the right bit-shifted probability estimator value is used to update the interval.
