    Abstract: An image decoding method 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 MSB that may calculate the MSB of POC of a long-term reference picture relative to the current picture, and flag information that represents whether there is MSB; and eliciting the set of reference pictures by using received MSB 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 is the same as 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.

    Abstract: A deblocking filtering method, a boundary strength (bS) deriving method, and encoding/decoding method and apparatus using the methods are provided. The bS deriving method includes the steps of: deriving a boundary of a deblocking filtering unit block which is a unit block on which deblocking filtering is performed; and setting a bS for each bS setting unit block in the deblocking filtering unit block. Here, the step of setting the bS includes setting a bS value of a target boundary corresponding to the boundary of the deblocking filtering unit block as the bS setting unit block.

    Abstract: The present invention relates to a method for signaling image information and to a decoding method using same. The method for signaling image information according to the present invention comprises: a step of performing inter-prediction for a current picture; and a step of signaling information including the result of said inter-prediction and reference picture information indicating reference pictures usable in said inter prediction, wherein said reference picture information contains pieces of picture order count (POC) information of said usable reference pictures. The POC information of said usable reference pictures in said reference picture information is configured such that POCs for the pictures existing before said current picture in terms of a POC sequence are located at the front, and POCs for the pictures existing after said current picture in terms of a POC sequence are located following the POCs located at the front.

    Abstract: 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.
