1. A video decoding method performed by a decoding apparatus, the method comprising:
receiving information related to a reference picture, wherein the information related to the reference picture comprises most significant bit (MSB) information related to an MSB of a picture order count (POC) of a long-term reference picture (LTRP) for a current picture, and a flag related to whether the MSB information is present;
deriving the POC of the LTRP for the current picture using the MSB information based on a value of the flag being 1;
deriving a reference picture list for a current block in the current picture based on the POC of the LTRP for the current picture;
performing inter prediction for the current block based on the reference picture list;
generating a reconstructed block for the current block based on a result of the inter prediction; and
applying a deblocking filter to the reconstructed block,
wherein the value of the flag is equal to 1 based on a case that there is more than one POC value, in a previous picture POC set, for which the POC value modulo MaxPicOrderCntLsb is equal to a least significant bit (LSB) of the POC of the LTRP, MaxPicOrderCntLsb is a predetermined max least significant bit value, wherein the previous picture POC set is derived based on a previous picture of the current picture in decoding order,
wherein the previous picture used to derive the previous picture POC set has a temporal identifier equal to 0,
wherein the previous picture POC set includes 1) a POC of each picture that is referred to by the previous picture, and 2) a POC of each picture following the previous picture in decoding order and preceding the current picture in decoding order, and
wherein the flag and the MSB information are received through a slice header.
