Implementation of JCT3V_H0044
MACRO H0044_POC_LSB_NOT_PRESENT

Constraint checking on the value of poc_reset_idc and poc_lsb_val
When poc_lsb_not_present_flag[ i ] is equal to 1

• When slice_pic_order_cnt_lsb is greater than 0, poc_reset_idc shall not be equal to 2.
• When full_poc_reset_flag is equal to 1, poc_lsb_val shall be equal to 0.
