| number of bits that structure short_term_ref_pic_set( num_short_term_ref_pic_sets ) takes in slice segment header when short_term_ref_pic_set_sps_flag equals 0. if short_term_ref_pic_set_sps_flag equals 1, the value should be 0. the bit count is calculated after emulation prevention bytes are removed from bit streams. This variable is used for accelorater to skip parsing the short_term_ref_pic_set( num_short_term_ref_pic_sets ) structure. | |
