摘要
In a method and apparatus for context-adaptive binary arithmetic coding (CABAC) of a syntax element, the bin string corresponding to the syntax element is processed by context-adaptive arithmetic coding with a reduced number of contexts using the bin-level bypass mode, bin-level context sharing, or both. The syntax element belongs to a group comprising merge_idx, ref_idx_1c/ref_idx_10/ref_idx_11, pred_type, and cu_qp_delta. In one embodiment, the syntax element corresponds to merge_idx and three bins of the bin string with bin indices corresponding to 1, 2 and 3 are coded in the bin by-pass mode. In another embodiment, the syntax element corresponds to ref_idx_1c/ref_idx_10/ref_idx_11 and one or more bins of the bin string with bin indices larger than 1 for larger than 2 are coded in the bin bypass mode.
