Abstract

Systems, methods, and instrumentalities are disclosed for entropy coding of on the border predicted probabilities. A context adaptive binary arithmetic coding (CABAC) probability associated with a bit may be determined. A range of a least probable symbol (LPS) may be determined based on the CABAC probability and a probability prediction threshold. The bit may be entropy decoded or encoded based on the range of the LPS. The range of the LPS may be determined to be a minimum range value based on the CABAC probability being less than or equal to the probability prediction threshold. The probability prediction threshold may be a first probability prediction threshold. A second probability prediction threshold may be determined that is greater than the first probability prediction threshold.
