Claim 3:
4. The method of claim 3, wherein the one type of the syntax elements is one of:
a first type of syntax elements, denoted by sig_coeff_flag, indicating whether an absolute transform coefficient level of the respective transform coefficient, denoted by absLevel, is zero or larger than zero;
a second type of syntax elements, denoted by par_level_flag, indicating, when the absolute transform coefficient level of the respective transform coefficient is non-zero, a parity of the absolute transform coefficient level of the respective transform coefficient;
a third type of syntax elements, denoted by rem_abs_gt1_flag, indicating, when the absolute transform coefficient level of the respective transform coefficient is non-zero, whether (absLevel-1)>>1 is greater than 0 for the respective transform coefficient; or
a fourth type of syntax elements, denoted by rem_abs_gt2_flag, indicating, when (absLevel-1)>>1 is greater than 0, whether the absolute transform coefficient level of the respective transform coefficient is greater than 4.
