Abstract:
An image decoding method according to the present invention includes: receiving information on a set of reference pictures for configuring a set of reference pictures of a current picture, wherein the information on the set of reference pictures includes the most significant bit (MSB) information that may calculate the MSB of the picture order count (POC) of a long-term reference picture relative to the current picture, and flag information that represents whether there is MSB information; and eliciting the set of reference pictures by using received MSB information when the flag information is 1, and performing marking on the reference picture, wherein the flag information may be 1 when a temporal sub-layer identifier is 0, and there is at least one POC value for which a remainder obtained by dividing by a maximum value MaxPicOrderCntLsb capable of being represented by the LSB is the same as the least significant bit (LSB) of the POC of the long-term reference picture, in a set of POCs of a previous picture including POC values related to the previous picture that may not be discarded without affecting whether other pictures of the same temporal layer may be decoded.

Claim (Index 11):
A video decoding method, by a decoding apparatus, the method comprising:\n receiving reference picture set (RPS) information, wherein the RPS information comprises flag information indicating whether most significant bit (MSB) information for calculating an MSB of a picture order count (POC) of a long-term reference picture (LTRP) for a current picture is present, and wherein the RPS information further comprises the MSB information when a value of the flag information is equal to 1; deriving the POC of the LTRP based on the MSB information when the value of the flag information is equal to 1, wherein the value of the flag information is equal to 1 when 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, and the previous picture has a temporal sub-layer identifier equal to 0, and wherein the previous picture POC set derived based on the previous picture of the current picture includes 1) a POC of each reference picture in an RPS for the previous picture in decoding order, and 2) a POC of each picture following the previous picture in decoding order and preceding the current picture in decoding order; deriving an RPS for the current picture based on the POC of the LTRP; performing inter prediction for a block in the current picture based on the RPS; and reconstructing the current picture based on the result of the inter prediction, wherein the flag information and the MSB information are configured in a slice header.
