description Disclosed is a video decoding method which includes receiving reference picture set (RPS) information for constructing an RPS for a current picture, the RPS information comprising most significant bit (MSB) information for calculating an MSB of a picture order count (POC) of a long-term reference picture (LTRP) for the current picture and flag information indicating whether the MSB information is present; and deriving the RPS using the received MSB information and marking a reference picture when the flag information is 1, the flag information equal to 1 if there is more than one POC in a previous picture POC set comprising POCs relating to a previous picture that has a temporal sub-layer identifier equal to 0 and cannot be discarded without affecting decodability of another picture in the same temporal layer for which the POC modulo MaxPicOrderCntLsb is equal to an LSB of the POC of the LTRP, MaxPicOrderCntLsb is the max least significant bit (LSB) value.
