Claim 5:
6. The method of claim 1, wherein the format rule specifies that a value of a first variable NumWeightsL1 corresponding to weights for the particular RPL is derived as follows:
if(!pps_weighted_bipred_flag∥(pps_wp_info_inph_flag && num_ref_entries[1][RplsIdx[1]==0))
NumWeightsL1=0

else if(pps_wp_info_inph_flag)
NumWeightsL1=num_l1_weights

else
NumWeightsL1=NumRefIdxActive[1],

wherein pps_weighted_bipred_flag is the fifth syntax element, pps_wp_info_inph_flag is the sixth syntax element, num_ref_entries[1][RplsIdx[1] is the third syntax element, num_l1_weights is the fourth syntax element, and NumRefIdxActive[1] is a second variable indicating a number of active reference pictures in the reference picture list 1 that allowed to be used to code at least one slice.
