Abstract

To provide a method, an apparatus, and a non-transitory computer-readable storage medium for video encoding and decoding.SOLUTION: A video decoding method includes a step 2702 of receiving, by a decoder, a Sequence Parameter Set (SPS) rice extension flag indicating whether an extension of rice parameter derivation for binarization of abs_remainder and dec_abs_level is enabled. A second method includes a step of receiving, by the decoder, a Sequence Parameter Set (SPS) rice adaption enabled flag indicating whether rice parameter derivation for binarization of abs_remainder and dec_abs_level is initialized at start of each transform unit (TU) using statistics accumulated from previous TUs.SELECTED DRAWING: Figure 17
