摘要
In one implementation, the CCB counting methods are unified between the transform residual coding process and Transform Skip (TS) residual coding process. In one example, in TS residual coding, the CCB counting excludes the coeff_sign_flag so that syntax used for CCB count is unified for the two residual coding processes. In addition, a separate maximum number of context coded bins can be specified and used for coeff_sign_flag only. In another example, in TS residual coding, the maximum number of CCB count is reduced from TB_size*2 for a TB to TB_ size*1.75, or more generally both the maximum CCB counts of the transform residual coding and TS residual coding are set to an identical value, so that the maximum CCB count is unified for the two residual coding processes.
