1118	Inference rule for ph_poc_msb_cycle_present_flag	naeri.park		"According to clause 8.3.1, ph_poc_msb_cycle_present_flag is used on derivation process of POC.
However, since ph_poc_msb_cycle_present_flag is used to derive the MSB of POC (PicOrderCntMsb), even though ph_poc_msb_cycle_present_flag is not present, decoder may derive the value of PicOrderCntMsb incorrectly.

Therefore, the inference rule of ph_poc_msb_cycle_present_flag is required. The possible solution adding editorial change is as follows.

'''ph_poc_msb_cycle_present_flag''' equal to 1 specifies that the syntax element ph_poc_msb_cycle_val is present in the PH '''''and used for deriving the value of PicOrderCntMsb'''''. ph_poc_msb_cycle_present_flag equal to 0 specifies that the syntax element ph_poc_msb_cycle_val is not present in the PH. '''''When not present, ph_poc_msb_cycle_present_flag is inferred to be equal to 0'''''. When vps_independent_layer_flag[ GeneralLayerIdx[ nuh_layer_id ] ] is equal to 0 and there is a picture in the current AU in a reference layer of the current layer, the value of ph_poc_msb_cycle_present_flag shall be equal to 0.
