摘要
A method and apparatus for syntax element context-adaptive binary arithmetic coding is provided. A method and apparatus for context-adaptive binary arithmetic coding (CABAC) of syntax elements is disclosed. The binary string corresponding to the syntax element is processed by context-adaptive operational coding with a context of reduced quantity using binary level bypass mode, binary level context sharing, or both. The syntax element belongs to a group including merge_idx, ref_idx_lc / ref_idx_l0 / ref_idx_l1, pred_type, and cu_qp_delta. In one embodiment, the syntax element corresponds to merge_idx and the three binary values of the binary string with binary exponents corresponding to 1, 2 and 3 are coded in binary bypass mode. In another embodiment, the syntax element corresponds to ref_idx_lc / ref_idx_l0 / ref_idx_l1, and one or more binary values of a binary string having a binary index greater than 1 or 2 are encoded in binary bypass mode. .
